　　Cctv news(Reporter Zhang Qi): It’s the year of 2008. I have to go home no matter how far I go. Missing turns into a small ticket in hand, which brings us closer to home. Reunion is the biggest belief in the Spring Festival, but some people give up silently. They turn their backs on the train home year after year for the same reason.

　　one

　　Fourteen platforms, eight waiting rooms, two pre-inspection halls, two passages and a square in front of the station are the "battlefields" that Su Hailin has adhered to for six years.

　　At five o’clock in the morning, thick police uniforms can’t stop the cold wind of the twelfth month. Su Hailin’s running figure appeared in the street again, as usual.

　　At the end of 2013, Su Hailin transferred from the 38 th Army to work in the Beijing Railway Station Police Station. For six years, he insisted on getting up early and running to the office, "to keep his body active and always ready to deal with emergencies." Every working day, Su Hailin patrols back and forth in his "battlefield", and he never misses every position of platforms, shops and squares. He has to walk 30 to 40 kilometers and take more than 50,000 steps a day. He wove a net with his own steps, so that criminals could not start.

　　"Spring Festival travel rush and summer vacation are different, so we should observe more and think hard, and be good at summing up laws and experiences." As an expert in anti-pickpocketing, Su Hailin has rich practical experience and is good at learning and thinking, and is a "all-rounder" in the eyes of colleagues. Theft, mobile phone fraud, extortion, criminals commit crimes in a variety of ways, but he can always see the confession and go straight to the point, even the most cunning old thief can only give in easily.

　　In Su Hailin’s eyes, it is a happy thing to let ordinary people get home by car in a down-to-earth manner and smoothly. In order to do this "little thing" well, Su Hailin made great efforts: he put on his hat and glasses, disguised himself as a passenger, spread a mat in a corner of the station and pretended to be asleep, waiting for the criminals to take it down in one fell swoop when they committed crimes in the middle of the night.

　　Su Hailin has his own "thirty-six skills" to catch thieves, but catching thieves has never been Su Hailin’s purpose. What he wants to see most is to achieve "world without thieves" without committing a crime. Vendors stationed in Beijing Railway Station all know that there is a Su police officer who practices martial arts at the police station, carrying nunchakus with him and dancing a few times from time to time. Su Hailin comes from Wen ‘an, Hebei Province, the hometown of martial arts, and has studied Tongbi Boxing, Wing Chun Boxing and Bagua Palm since childhood. Su Hailin said that he punched a few times at the station and practiced nunchakus in order to let those little thieves see him and shock them. "We should not be afraid of criminals, and the police uniform on us reminds us that we can’t retreat."

　　During the period of Spring Festival travel rush, the railway station was crowded with people and things, and Su Hailin’s pace was even more hurried. He started his patrol and handled the police situation at eight o’clock, and it was common that he didn’t have time to have lunch, so he had to drink a glass of water in a hurry during the break. After the last shift, Su Hailin returned to the dormitory at one o’clock in the morning.

　　When asked how to spend the Spring Festival, Su Hailin said calmly: "The Spring Festival is nothing special for us. Nothing is a good thing, but we feel a little guilty about our family." On New Year’s Eve, I was on duty at work and called my family. Su Hailin said that she was used to such a New Year. Near the Spring Festival, on the day of family reunion, Su Hailin’s work is even busier. Looking at her husband, Dai Yue, traveling in the forefront of Spring Festival travel rush, his wife once shed tears. She made a New Year’s wish in a circle of friends: I hope my husband is getting better and better. In the early morning, Su Hailin returned to the dormitory after a day’s work, and also gave his blessing to his wife: I hope her smile often.

　　"Only when a person loves his job can he focus on little things and really do this job well." Sticking to the mission is Su Hailin’s belief. When he was in the army, he told himself: "You are not afraid to go to the battlefield when you wear military uniforms." Now his "battlefield" has changed, but his duty to protect the people has not changed. Always maintaining the standard military posture of "three stands and two harvests", Su Hailin’s pace is forceful.

　　Dressed in olive green and a pair of white gloves, Fu Qiang, an armed police officer on duty, and his comrades stood upright at the Beijing Railway Station, staring at the passing passengers and guarding their way home warmly.

　　Fu Qiang is 26 years old, but he has been on duty for the Spring Festival for seven years in a row, and he hasn’t been home for the Spring Festival for seven years. Lost luggage, sudden illness, lost children, asking for directions … … The problems encountered by passengers are varied, and the armed police should be the "master key" to solve these problems.

　　At dawn, I went to the sentry post, and returned to the camp near midnight. On average, I was on duty for 16 hours every day, including the ticket collection hall, the security checkpoint, the waiting room and the exit. Every sentry post had left the figure of Fu Qiang. Over the years, Fu Qiang has been used to standing on every shift on the day of family reunion and sending off a train home. When the New Year’s bell rings, he can have a video conversation with his family, then take time to rest, and go to the temple fair on duty and maintain order in the early morning of the New Year’s Day. Ditan temple fair, Lama Temple Fair, these lively temple fairs, he has been to, but they have nothing to do with reunion and sightseeing.

　　"Others holiday we pass, find one thousand days to fight for one thousand days. When others need us, they should pay, and it is our responsibility to stick to the front line of duty. " During his seven years in the army, Fu Qiang has changed. He said that the army is a school, and his disciplined and courageous education has made him grow up, learn to be content and understand his responsibilities.

　　In 2014, 19-year-old Fu Qiang joined the army after graduating from high school. This was the first time that he left home and was on duty at Beijing Railway Station. As an adult, he became the guardian of the people. "The scene at that time was vivid. My post was in the waiting room on the second floor, and I changed jobs every two hours." During the two hours of standing guard, Fu Qiang was always nervous, always vigilant, preventing emergencies and ensuring that he could cope with various situations.

　　There will always be gains from paying, and the biggest gain of Fu Qiang is respect. There are often sensible children who run to Fu Qiang’s sentry post to pay him a tribute, and their innocent eyes are full of worship. Travellers will take the initiative to say hello, and this feeling of being trusted is the most valuable to Qiang. "It is my honor to be on duty at Beijing Railway Station", which is the strength that Fu Qiang has adhered to for seven years.

　　Fu Qiang told reporters that in the Armed Police Force, there are many comrades who have not returned home for many years like him. Like Fu Qiang, comrades-in-arms Zhao Chuanhao and Mi Wenxin are "veterans" who have not returned home for the New Year in five or six years. They come from all over the world and stay in the front line all the year round for the common task.

　　In Zhao Chuanhao’s memory, he was happiest when he was a child. He could wear new clothes to join in the fun with adults and taste delicious meals from relatives. Now he doesn’t have any special wishes. He just wants to get together with his relatives and have dinner together when he goes home. Mi Wenxin hopes to eat the vinegar-fried potato shreds made by his mother as soon as possible. Before he came to the army, he always rushed to eat with his sister and dipped all the vegetable juice. Now he is thousands of miles away from home, which has become the taste of home in his mind.

　　What is the year? It’s home, it’s reunion. For those who stick to their posts, year is the responsibility, and family reunion is the peace of mind.

　　CCTV News:In addition to the five social insurances of pension, medical care, work injury, unemployment and maternity, a new social insurance — — Long-term care insurance is being gradually extended in China to provide a guarantee for the disabled elderly to provide decent old-age care.

　　In China, 7% of families have elderly people who need long-term care.

　　The fourth sampling survey on the living conditions of the elderly in urban and rural areas of China shows that there are more than 40 million disabled and semi-disabled elderly people in China, among which severely disabled elderly people account for a considerable proportion. At the same time, relevant research reports show that 7% of families in China have elderly people who need long-term care, and the care they actually receive at present.Most of them are provided by spouses, children or relatives, and the proportion of services provided by third-party institutions is extremely low.

　　Jin Weigang, Dean of China Academy of Labor and Social Security:With the continuous growth of population and the acceleration of aging, the number of disabled, semi-disabled and other people with dementia and mental disorders will further increase, and the social demand for long-term care of such groups is growing. Therefore, it is urgent to establish and improve relevant systems.

　　Facing the objective needs of a large number of disabled people for long-term care, the long-term care insurance system came into being in China. In 2016,Piloting the long-term care insurance system in 15 cities and two key provinces across the country., explore the establishment ofA social insurance system in which funds are raised by mutual social assistance to provide funds or service guarantees for the basic living care of long-term disabled people and medical care closely related to basic life.

　　Zhu Yaoyin, deputy director of the Office of the National Working Committee on Ageing, pointed out that exploring the establishment of a long-term care insurance system is an important strategic measure to actively respond to China’s population aging.

　　The establishment of long-term care insurance system can not only meet the care needs of the disabled and semi-disabled elderly, improve their quality of life, make them obtain the greatest degree of life independence and personal dignity, but also relieve the care pressure of the elderly family members, especially their children.

　　What is long-term care insurance?

　　On April 12, 2017, the General Office of the People’s Government of Shandong Province published the Opinions on the Trial Implementation of the Long-term Care Insurance System for Employees (hereinafter referred to as the Opinions), and decided to establish a comprehensive long-term care insurance system for employees in the province in about three years.

　　Taking Shandong as an example, let’s learn about the coverage, payment methods and treatment payment of long-term care insurance.

　　Insurance coverage

　　Employees and retirees who participate in the basic medical insurance for employees.

　　Payment method

　　Through the employee medical insurance pooling fund, unit supplementary medical insurance funds, individual contributions and financial subsidies, welfare lottery public welfare fund and other channels to solve. Among them, the individual contribution is not less than 30% of the total fund-raising, and the individual contribution can be withheld from the employee’s personal medical insurance account.

　　Municipalities should reasonably determine specific financing methods, financing ratios and financing standards according to the affordability of all aspects and the level of long-term care insurance benefits for employees.

　　Scope of protection

　　Focus on ensuring the daily life care and medical care closely related to basic life of the insured who have been disabled or semi-disabled for a long time.

　　Municipalities can start at a low level according to local security needs and financial affordability, scientifically determine key security groups and specific security projects, and gradually adjust with economic development and financial support capacity improvement.

　　Treatment payment

　　The cost of nursing service is shared by the nursing insurance fund and the individual of the security object in proportion or according to the quota, and appropriate care can be given to the poor.

　　Long-term care insurance benefits can be differentiated according to different forms such as institutional care and home care, different levels of care, and different ways of providing nursing services.In principle, the payment standard of nursing service fees within the prescribed scope is controlled at about 75%..

　　All localities should actively explore ways to properly link the enjoyment of nursing treatment with individual contributions and strengthen personal responsibility.

　　Long-term care insurance has covered about 48 million people

　　Song Fuxing, president of China People’s Health Insurance Co., Ltd., said that after two years of exploration, the long-term care insurance system has been launched in 15 pilot cities such as Qingdao and Shanghai and in non-pilot areas of many provinces and cities such as Beijing and Hebei.Covering about 48 million people., and achieved phased results.

　　By the end of 2017, more than 75,000 people had enjoyed the guaranteed treatment, paying about 570 million yuan for nursing insurance, and the fund paid more than 70%.While effectively reducing the economic burden of disabled people and their families, it has driven the investment in related industries in the pilot areas to about 7 billion yuan, directly stimulating more than 40,000 jobs, and effectively promoting the development of the nursing service market.

　　Qingdao, Shandong

　　In 2012, Qingdao, Shandong Province took the lead in establishing a long-term medical care insurance system in China.

　　Since 2017, Qingdao has included severely demented elderly people in the scope of long-term care.

　　From April 1st this year, Qingdao began to implement the upgraded long-term care insurance system of "whole person and full responsibility". On the basis of the original long-term medical care, basic life care was included in the scope of employee care.

　　Up to now, more than 50,000 people in Qingdao have enjoyed nursing care, and the accumulated expenditure on nursing insurance funds is nearly 1.5 billion yuan, and the number of nursing service institutions has grown to more than 600.

　　Ningbo City, Zhejiang Province

　　In 2017, the "Ningbo Long-term Care Insurance System Pilot Program" was launched. In the pilot stage, the insured persons who participate in the basic medical insurance for employees in the pilot area (excluding those who participate in hospitalization medical insurance) do not need to pay additional fees to participate in long-term care insurance.

　　Among them, insured persons who are disabled due to old age, illness, disability and other reasons, after no less than 180 days of treatment, are assessed to meet the criteria of severe disability, can not take care of themselves at all, and need long-term care, and can enjoy long-term care insurance benefits from the next month after the assessment conclusion is made.

　　Not long ago, the first batch of 574 employees in Ningbo who were assessed as severely disabled began to enjoy long-term care insurance benefits, and the long-term care insurance fund paid 1.33 million yuan.

　　Shortage of nursing talents becomes the biggest shortcoming.

　　The long-term care insurance system has just started. Experts believe that the current system is not suitable for the new trend of rapid population aging and the rapidly growing demand for nursing services for the elderly, and it is urgent to further strengthen the system design and practical exploration.

　　Zhu Yaoyin, Deputy Director of the Office of the National Working Committee on Ageing:The talent problem is an important bottleneck restricting the development of China’s old-age care service at present. There are many problems, such as fewer people, older people, lower education level and lower professional ability.

　　According to estimates, based on 40 million disabled elderly people, according to the 3∶1 nursing service configuration, more than 10 million nursing staff are needed. At present, there is a shortage of nursing service personnel. Less than 10% of nursing staff for the aged hold certificates, and most nursing staff in old-age care institutions are concentrated in 40-mdash; In the 50-year-old age group, most of them have academic qualifications below junior high school, and most of them come from rural areas with extensive services. According to some data, there are only more than 10 colleges and universities in China with nursing specialties for the aged, which is difficult to meet the market demand.

　　CCTV News:According to the news of "Tangshan Provident Fund" WeChat WeChat official account on May 1, Tangshan Housing Provident Fund Management Center has further optimized and adjusted the housing provident fund use policy. Among them, it is proposed that the deposit of the employee’s first suite provident fund loan cancel the balance hook. The policy stipulates that if employees under the age of 45 in Tangshan purchase the first set of self-occupied housing, the cancellation of the loan amount will be linked to the deposit balance of the borrower’s housing provident fund on the premise that they have paid the housing provident fund for more than 6 months (inclusive) continuously and meet the repayment ability and do not exceed the corresponding maximum loan limit.

　　In addition, we will increase policy-oriented housing support to meet the needs of new citizens. Taking the policy-oriented housing of Tangshan Anju Group as a pilot, we will launch a policy of rent-and-purchase of affordable housing, give full play to the mutual protection role of the housing provident fund system, and continue to help the implementation of the rent-and-purchase housing system.

　　The policy stipulates: (1) The cancellation of the loan amount is linked to the deposit balance of the housing provident fund of the borrower on the premise that the paid-in employees who purchase the newly-built policy housing and are the first self-occupied housing have paid the housing provident fund continuously for more than 6 months (inclusive) and meet the repayment ability and do not exceed the corresponding maximum loan amount; (2) For the paid employees who lease the affordable rental housing and talent apartments built, acquired and rebuilt by Tangshan Anju Group, the provident fund will be opened to offset the rent, so as to realize the linkage between the rental management platform of affordable rental housing and talent apartments and the housing provident fund account.

　　This policy will be implemented on June 1, 2023.

　　Xinhua News Agency, Guiyang, May 13th Title: Green, clear, accessible and rich — — "Nirvana" of Wujiang River

　　Xinhua News Agency reporters Li Qianyu and Zheng Minghong

　　Puke Village, Hezhang County, Bijie City, Guizhou Province, is located in the upper reaches of the Wujiang River, with an altitude of more than 2,300 meters, surrounded by mountains and a lush forest of 10,000 mu.

　　At the end of April, Bijie Forestry Bureau issued a forestry carbon ticket for puffin village. "With this forestry carbon ticket, the air purified by the 10,000-mu forest in our village will become a circulating asset in the future, and the people will have another way to increase their income." Wen Junfu, secretary of the Party branch of Haique Village, said.

　　More than 30 years ago, due to the harsh ecological environment in karst mountainous areas, the local area fell into the dilemma of "more reclamation and more reclamation", and the forest coverage rate was less than 5%. Since 1987, puffin village has planted trees on a large scale, and the former "Heshangpo" has now become a forest of 10,000 mu, with a forest coverage rate of 77%.

　　The cargo ship carrying phosphorus ore set off from Luowang River Wharf in Kaiyang Port Area of Guiyang City and sailed downstream along Wujiang Channel (photo taken on November 16, 2021). Xinhua News Agency reporter Tao Liang photo

　　Forestry carbon ticket is the certificate of the income right of forest carbon emission reduction, the "identity card" of forest carbon sequestration increment as asset transaction, and can be used as loan pledge to participate in carbon ticket storage, transaction and financing.

　　This forestry carbon ticket in Haique Village covers an area of 7,346.5 mu of forest land, and the carbon emission reduction monitored from 2016 to 2020 is 34,627.7 tons. According to the average unit price of 30 yuan/ton, which is relatively low in recent years, this carbon ticket is expected to realize carbon trading value of about 1.04 million yuan.

　　The ecological management of puffin village is a microcosm of ecological restoration in Wujiang River Basin.

　　Wujiang River is the mother river of Guizhou and the largest tributary of the south bank of the upper reaches of the Yangtze River. Wujiang river basin bears more than half of the population and economic aggregate of Guizhou province. A few years ago, due to ecological fragility and outstanding environmental protection problems, Wujiang once sounded an ecological alarm. Since the 18th National Congress of the Communist Party of China, Guizhou has grasped the construction of ecological civilization with unprecedented efforts, promoted the ecological restoration of the Wujiang River Basin, and the Wujiang River ushered in nirvana rebirth.

　　Wujiang river basin has a phosphorus chemical production base rich in phosphate rock resources. It is difficult to control phosphorus in Wujiang River.

　　"The river suddenly turned white, and my hands were still greasy." People in wujiang town, Bozhou District, Zunyi City once told reporters that when the pollution was serious, the whole river surface of wujiang town River was dyed "rice soup color" by sewage.

　　Through investigation, it was found that the pollution originated from a karst spring named No.34 Spring Eye in wujiang town. The total phosphorus and fluoride in the vicinity of the spring eye exceeded the standard by hundreds of times, and all the sections in Zunyi downstream of the spring eye were inferior to Grade 5. The source of pollution is phosphogypsum produced by Guizhou Phosphate Group, which is 16 kilometers away from the spring. Phosphorus-containing sewage produced by phosphogypsum leaks underground and flows into Wujiang River from No.34 spring through the underground water system.

　　As the first batch of national ecological civilization experimental zones, Guizhou has overcome difficulties by means of "iron fist pollution control", and the pollution control of No.34 spring is listed as the "No.1 Project" for environmental pollution control in Guizhou Province. Wang Mei, environmental protection director of the Safety and Environmental Protection Department of Guizhou Phosphating Group, said that in order to solve the pollution problem, the enterprise built the third-phase sewage treatment facility at the outlet of the spring, and the whole system was turned on during the flood season, which can realize the collection, treatment and standard discharge of 15,000 cubic meters/hour of spring water, and the enterprise invested 1.1 billion yuan in environmental protection treatment.

　　In order to solve the problem of excessive total phosphorus in Wujiang River, Guizhou adheres to the management idea of "treating both the symptoms and root causes, giving priority to the source and covering the bottom at the end", highlights rigid measures in the regulation of "three phosphorus" in phosphate rock, phosphorus chemical industry and phosphogypsum storage, and fundamentally solves the phosphorus pollution problem in Wujiang River by implementing a package of pollution prevention measures. According to the data released by the Department of Ecology and Environment of Guizhou Province, in 2021, the water quality of the main stream of Wujiang River reached Class II standard, and the overall water quality of the basin was "excellent", and the excellent rate of 45 state-controlled water quality monitoring sections reached 100%.

　　The gratifying changes don’t stop there.

　　Wujiang River has been the main shipping route of Guizhou Unicom since ancient times. After 2003, due to the construction of several cascade hydropower stations and the lack of synchronous navigation facilities, the waterway of Wujiang River was blocked. In order to build a "golden waterway", Guizhou has incorporated the construction of Wujiang waterway into the overall deployment of traffic construction.

　　The navigation project of Goupitan Hydropower Station, which was put into trial operation in June 2021, is regarded as the key to Guizhou’s Tongjiang River reaching the sea. The head difference of Goupitan navigation is 199 meters, and it is operated by a three-stage vertical ship lift. All ships have to take the "water elevator" when passing through the Wujiang Goupitan Hydropower Station, showing the wonder of "water hanging in the air and ships traveling in the sky".

　　In recent years, the large ship lifts of Goupitan, Silin and Shatuo power stations have been put into operation one after another, and the Wujiang waterway has been fully connected. In November, 2021, the Kaiyang Port Area of Guiyang Port made its maiden voyage to the Yangtze River, and 14 cargo ships carried 6,800 tons of phosphate rock, departing from Kaiyang Port Area of Guiyang Port and heading for Fuling, Chongqing. This marks the large-scale resumption of the "Golden Waterway" of Wujiang River, and the 500-ton ship can reach the Yangtze River directly.

　　"We have signed contracts for 200,000 tons of cement transportation and 300,000 tons of ore transportation, and the freight demand is large." Shen Bo, head of Zunyi yuqing county Pilot Shipping Co., Ltd., said that the company bought five 500-ton cargo ships last year and plans to build 10 new ships to meet the demand for transportation capacity.

　　Sinan County in the lower reaches of Wujiang River, Guizhou Sinan Shipyard, which has been depressed for many years, is recovering, and it is a busy scene. Zhang Zhenqiang, the head of the shipyard, told the reporter that after the resumption of navigation in Wujiang last year, the shipyard received a batch of "big orders" for the manufacture of passenger ships and 500-ton cargo ships from Wujiang Shipping Company, and everyone’s confidence doubled and their enthusiasm was full.

　　"The comprehensive recovery of Guizhou’s water transport will be promising." Han Jianbo, deputy director of the Guizhou Provincial Department of Transportation, said that the opening of the "Golden Waterway" in Wujiang not only opened up a new channel for "Guizhou goods coming out of the mountain", but also promoted the development of the shipbuilding industry, which will also promote the prosperity of the industry and provide new employment opportunities for the coastal people.

Social cow disease, what’s so good about it? Original Xiaobei Peking University Publishing House is included in the topic # Social phobia, 1# Internet neologism, 1# Hot Spots, 16.

Recently, many people want to get a "disease"-social arrogance.

What do you mean by "social arrogance"?

Literally, it is not difficult to understand: contrary to "social phobia", I am not timid in social aspects.

Whether you are a semi-acquaintance who has only met a few times or a stranger who has never met before, you can talk with confidence and Kan Kan, and never care about other people’s eyes and ridicule.

For social terrorists who are embarrassed and nervous when they get close to people, they are really envious.

The origin of the disease is beyond examination, but on various social and video platforms, there are legends that patients are getting wild.

"Social cow disease" has become

A hot topic that has been played more than 1.4 billion times on Tik Tok.

It has been found that parents and elders are high-risk groups of social arrogance.

Some like to sing loudly in the park intoxicated, and some can talk to anyone, so there is no one they don’t know well.

Some people have concluded that those who can eat the star bowl of rice have the genes of some social experts.

Sa Beining became the deputy director of the school radio station by "cheeky" self-recommendation; Lareina is an ordinary ice-breaking and hot-field expert; Child star Hu Xianxu has been "popular" since childhood ▼

Not only stars, but also their hospitable cats and dogs, human cubs who are bold and curious about the world, and even the edited Harry Potter have become proud symptom owners ▼

Bilibili praised the video of "Harry Potter’s social arrogance"

By next bam bam jun

There are also some people who boldly let go of themselves and have no psychological burden. Shouting in public, dancing passionately in public … all kinds of "out of line" behaviors are completely out of the question.

The eyes of the crowd are their stimulants.

Some of these behaviors are exaggerated shows, which earn attention and traffic through "wonderful people"; But behind the netizens’ hot discussion about the disease, there is a deeper psychological appeal.

The first one is the desire to "be brave to be yourself".

I believe that many students were educated as children to be "sensible children" and think for others; Actively capture other people’s emotional thoughts, so as to give an appropriate and decent response.

This can easily lead to the situation that in social interaction, people care too much about what others think of them and put their feelings above their own. At the extreme, it will become a "please-type personality":

Don’t dare to refuse the rude request of others; Excessive criticism from others, accept all the orders; I’m wrong and I can, but the word "no" is hard to say.

Compared with living in harsh self-examination all the time, "social arrogance" is very attractive because it ignores the freedom and "licentiousness" of others’ eyes.

People with flattering personality are usually people who are not confident enough. They are afraid that their "true self" is not good enough to be liked, so they are afraid of embarrassment, refutation and rejection.

This kind of "fear" makes them live in a cocoon house built by many "dare not" in public: they dare not attract the attention of others in a high-profile way, dare not recognize and affirm themselves, and even dare not express their thoughts, joys and sorrows in public.

One of the symptoms of social awesome:

Regardless of the eyes of others, boldly let go of your feelings.

This is also why with the growth of age and experience, some people have changed from "social fear" with trepidation to social experts who dare to speak out-

On the one hand, it is the self-confidence brought by the accumulation of social skills and work ability; On the other hand, it is gradually recognized that "other people’s opinions" in social communication are actually not that important; Sometimes it is even fictional and imaginary, and it is the rules and regulations we impose on our words and deeds.

When you watch the video of "social madness", you feel that "it’s so cool not to care about others", you may want to reflect:

How long has it been since you took good care of your needs and made allowance for your feelings?

In addition to hoping to "be brave and shine with confidence", Xiaobei thinks that "social arrogance" is also popular because it represents a kind of high emotional intelligence social skills to some extent.

It’s too difficult to be a man!

However, this society with high speed and information explosion always seems to give more favor and preference to children with high emotional intelligence and ability to be human.

In the workplace, under the same basic conditions, most employees who know how to show their abilities and achievements "mix" better;

In school, it is often the active and cheerful children who are more liked by teachers and classmates. Wherever they go, they are C-places with their own aura and prosperity;

Even in leisure activities, people who can socialize can often make friends or even "take off the bill" as soon as possible …

A netizen in the Douban group posted about his "social cow disease", which aroused everyone’s envy:

See "Douban Goose Group" in the original post.

The comment "How did this disease get infected" received more than 10,000 praises.

The landlord’s powerful examples include:

Get acquainted with colleagues within one week every time you enter a new unit; It is recognized as the "warm field king"; Naturally praise the leadership without affectation and actively report to the leadership; I quickly mingle with people from all walks of life … I get the most evaluation that my emotional intelligence is super high and exquisite.

Interestingly, at the end of the article, the landlord said that he was actually a contradiction:

In fact, my true personality is inferior and introverted.

The comment area has learned a lot: awesome, but how to overcome the inner introversion and inferiority? Others asked: Is this "soaring acting"?

This statement is actually traceable.

Erving goffman, an American sociologist, put forward a famous theory of "parody".

In the theoretical masterpiece "Self-Presentation in Daily Life", he compared society to a theater, compared social members of different genders, classes and occupations (that is, you and me) to actors who play different roles in society, and compared interpersonal communication to acting.

For example, a good boss should be strong and charming, a qualified friend should be patient and enthusiastic, a decent middle class should be proficient in using steak knives and forks, and a female star on TV should be glamorous …

In the social operation, everyone is playing his "role" conscientiously.

Why do we need to "perform"?

Gofman put forward a concept: impression management.

In the process of interaction, people will always consciously or unconsciously "show" themselves to each other, thus shaping others’ impressions of themselves.

When a person appears in front of others, they usually want to know about this person or call up all kinds of information they have about this person.

They will be interested in his general socio-economic status, his self-concept, his attitude towards them, his ability and his trustworthiness.

This is due to some practical reasons: obtaining the information of an individual helps to define the situation, so that others can know in advance what the individual expects of them, and what they may expect of the individual, so as to make appropriate responses.

In the words of Gustav Ichheiser:

An individual will have to take action to expresses himself intentionally or unintentionally, and in turn, others will have to accept the impressed he has made in some way.

In this sense, people who are good at socializing are also good at "performing".

They can convey all kinds of symbols and information through appropriate and accurate words, actions and even expressions in interpersonal communication, so as to guide and even shape others to have a specific impression on themselves.

People who are not very sociable, or lack such awareness, or are ashamed to express themselves, or are not good at adjusting their performances according to different scenes, environments and audiences.

But it is worth noting that people are not actors in the true sense, and they are not always acting. In reality, performances are always performed intentionally or unintentionally, not completely false, disguised and deceptive.

Just like Sa Beining, the representative of "social arrogance" cited by everyone, he dares to laugh at himself, is not afraid to make exaggerated expressions and performances in his interactions with people, is good at taking over stalks, and never lets words fall to the ground; This is absolutely inseparable from deliberate impression management and shaping of people.

But behind his super ability of reaction, logic and language expression, his personality, knowledge and insight-that is, "acting" the real part.

This is why the audience still likes the cuteness and sincerity in his personality.

Gofman also put forward a pair of interesting concepts in Self-Presentation in Daily Life: "foreground" and "backstage".

The front desk is "standard expressive equipment that individuals use intentionally or unintentionally during the performance"; Personal front desk refers to the appearance and behavior of the role played by the individual. The former is used to inform people of the social identity of the performer at this time, while the latter enables others to predict what role the performer will play in the situation.

The backstage is the area after the performer’s "performance", which is separated from the performance stage. It is a place that the audience can’t enter and see, and it is also a place where individuals can relax and rest.

Gofman believes that there is no clear boundary between the foreground and the background, and they are transformed according to the change of the situation faced by the performers.

The distinction between front and back actually explains why many people are introverted, reserved and inarticulate in front of strangers; In front of acquaintances, they will immediately become cheerful, enthusiastic and "lawless."

Whether it is a person’s state or being with close friends and acquaintances, it is our "backstage comfort zone", where we can occasionally put down our burdens, focus on our goals and relax ourselves.

Finally, Xiao Bei thinks that, except for the grandstanding, the qualities of courage, cleverness and humor in "social arrogance" play a positive role in interpersonal communication.

But what can make interpersonal relationships last for a long time must be proper limit and comfort. And the two must be based on mutual understanding and care.

On the one hand, we might as well accept ourselves boldly and try to show ourselves skillfully; On the other hand, loyalty to self is always a precious virtue. After all, life is like a play, and the greatest weapon for an actor who laughs last on stage is sincerity.

Yesterday, Shanghai Petrochemical boarded the hot search, not because of the anniversary, but because of the explosion and fire.

At 4: 28 on June 18th, the Chemical Department of Shanghai Petrochemical Company caught fire, and the fireball went straight into the sky, with explosions in many places. The live video shows that after the fire broke out, the flame spread and the whole factory area was covered with black smoke.

At that time, it was two or three kilometers away from the explosion point. An eyewitness said, "I thought it was thundering at first, and the sky behind it was red." According to its introduction, the explosion was more than one area. "Three explosions, two loud."

Weibo, the official of Sinopec Shanghai Petrochemical Co., Ltd., immediately responded that a fire broke out in the ethylene glycol plant area of the Ministry of Chemical Industry of Shanghai Petrochemical at around 4:00 on June 18th, and the company immediately launched the first-level plan, which is currently under emergency treatment.

At 10: 30 am yesterday, the latest news of "Shanghai Petrochemical Online" in Weibo, after preliminary verification, at present, an employee of Shanghai Petrochemical was slightly bruised on the arm and a driver of a third-party transport vehicle died. The specific reasons are under further investigation.

After the fire broke out, Shanghai 119 Command Center quickly dispatched rescue forces such as Jinshan, Fengxian and Chemical Industry Zone to the scene to fight the fire. Relevant personnel of the fire rescue detachment of Shanghai Chemical Industry Park said that as of 9: 00 on the 18th, the fire was basically controlled, but it was difficult to dispose of, and it is expected that it may still burn protectively for some time.

The area where the fire broke out was an ethylene glycol plant. Ethylene glycol is an important chemical raw material, and its production process is mainly the hydration of ethylene oxide, which is extremely flammable and explosive, so relevant safety rules will be formulated during production, transportation and storage.

And "protective combustion" is a kind of treatment method made by firefighters and rescuers according to the disaster caused by flammable and explosive substances such as ethylene glycol, which is also the usual treatment method for fires in large chemical refining units. The residual materials can be burned out in a controlled way, and then the next rescue work can be carried out. On the one hand, it can reduce the excessive cost of forced fire fighting, and on the other hand, it can prevent more serious secondary explosion.

It is reported that after the fire broke out, Sinopec Shanghai Petrochemical launched an environmental emergency plan at the same time, and continuously monitored the environment at the company’s factory boundary and external areas, and the monitoring of volatile organic compounds was normal. Arrangements have been made to strengthen the sampling and monitoring of rainwater outlets, and no impact has been found on the surrounding water environment.

Just the day before the accident, Shanghai Petrochemical just held the 50th anniversary celebration meeting. At the celebration meeting, the company put forward the goal and prospect of carrying forward the fine tradition of petroleum and petrochemical industry and the "Jinshan spirit" and striding forward towards the goal of building a "domestic leading and world-class" energy, chemical and new materials company. However, a big fire plunged Shanghai Petrochemical into the whirlpool of public opinion.

Shanghai Petrochemical Complex was built on June 18th, 1972. But a shocking fire and explosion happened on the same day 50 years later. Time coincidence aside, the decline in investment in safety may be one of the main causes of the explosion.

According to the social responsibility report disclosed by Shanghai Petrochemical, from 2019 to 2021, the company’s investment in production safety was 234.78 million yuan, 284.72 million yuan and 112.37 million yuan respectively, which was 60% lower than that in 2021. During the seven years from 2015 to 2021, the company’s major fire and explosion accidents and major liability accidents were all zero.

In addition, Shanghai Petrochemical Company just carried out overhaul and reconstruction in May. According to its WeChat official account information, in May, in order to ensure the stable and orderly epidemic prevention of the resident and personnel of the construction unit during the overhaul, the company set up four temporary overhaul contractors in the polyester east area, the polyester west area, the western area of the Ministry of Environmental Protection and Water Affairs and the ethylene glycol area of the Ministry of Chemical Industry.

There have been two explosion accidents in petroleum and petrochemical plants this year. The last explosion accident occurred in Qilu Petrochemical Company on April 24th, 2022. In less than two months, accidents occurred in petrochemical enterprises one after another. As a high-risk and explosive industry, it is particularly important for petroleum and petrochemical related enterprises to do a good job in safety prevention.

(Original title: Operation Review of the Board of Directors of Zhenhua New Materials in 2022)

The operating comments of the Board of Directors of Zhenhua New Materials in 2022 are as follows:

I. Discussion and analysis of business conditions

　　In 2022, China’s new energy vehicles continued to grow explosively. According to the data released by China Automobile Industry Association, in 2022, China’s new energy vehicles sold 6.887 million vehicles, with a year-on-year increase of 93.4%, accounting for 25.6% of domestic automobile sales in the same period (i.e. penetration rate). According to the statistics of EV-Voumes, the global sales of electric vehicles (BEV and PHEV) will be about 10.5 million in 2022, up 61% year-on-year. China has led the growth of global automotive electrification. The development of new energy vehicles is of great significance to enhance the competitiveness of the automotive industry, ensure energy security, improve air quality and cope with climate change. Therefore, the new energy industry still has broad development space in the future.

　　In 2022, the company’s sales revenue from ternary cathode materials was 13.5 billion yuan, accounting for 97% of the total revenue. Thanks to the growth of demand side of new energy vehicles, the company’s sales of ternary cathode materials increased by 34% year-on-year; The sales volume increased, the product structure was optimized, and the price of superimposed raw materials rose. The revenue of ternary cathode materials increased by 158% year-on-year.

　　In terms of product structure, based on the deep technical precipitation in the field of single crystals, during the reporting period, the company:

　　(1) High-nickel 8-series ternary cathode materials were continuously and steadily released, achieving a revenue of 5.075 billion yuan, up 143.3% year-on-year;

　　(2) Ultra-high nickel 9-series ternary cathode materials began to send samples to some customers in 2021, and delivered more than 10 tons in 2022;

　　(3) Medium-high nickel 6 series products have great cost-effective advantages in high-voltage scenarios, and the proportion of their main business income increased from 2.31% in 2021 to 15.85% during the reporting period;

　　(4) The medium nickel 5 series products have been continuously and stably exported for many years, and have been widely recognized by the downstream market by virtue of their stable and reliable technical performance. They are not only used in foreign high-end models, but also used in domestic mainstream models in batches.

　　While the new energy industry is booming, the price of some raw materials for lithium-ion batteries has risen sharply due to the imbalance between supply and demand, which has adversely affected the sustainable and healthy development of the industry. In order to alleviate this situation, from the perspective of battery raw materials, the company is committed to making breakthroughs through technological innovation. Sodium ion batteries have significantly better low-temperature performance than lithium ion batteries, which is very suitable for all-weather and all-regional electric vehicle market demand. The most important thing is that the supply chain of raw materials for sodium ion batteries is stable, which has important strategic significance for the future development of the new energy industry. 2022 is the early stage of sodium electricity industry. During the reporting period, the company’s sodium ion battery cathode materials have reached a comprehensive and in-depth cooperative relationship with domestic head battery customers by virtue of excellent performance and excellent cost performance advantages, with a cumulative shipment of dozens of tons. At the same time, the company has laid out corresponding patents, and the core technology is self-controllable, laying a solid foundation for business development in the next year.

　　

　　II. Description of the company’s main business, business model, industry and R&D during the reporting period.

　　(a) the main business, main products or services.

　　Since its establishment, the company has focused on the research, development, production and sales of cathode materials for lithium-ion batteries, mainly providing cathode materials for lithium-ion batteries used in new energy vehicles and consumer electronics products.

　　During the reporting period, the company made a breakthrough in the research and development and industrialization of cathode materials for sodium ion batteries. During the reporting period, it shipped dozens of tons, and the market application and promotion progressed smoothly, reaching a comprehensive and in-depth cooperative relationship with domestic head battery customers.

　　(II) Main business models

　　1. Purchasing mode

　　The main raw materials purchased by the company include ternary precursors, cobaltosic oxide, lithium carbonate and lithium hydroxide. The company has a materials department, which is responsible for supplier selection and material procurement.

　　2. Production mode

　　The company mainly produces according to orders. If it is judged according to the customer’s annual purchasing plan and market trend that the customer is expected to have a large order demand in the future, in order to reduce the future production pressure and effectively utilize the production capacity, the company will also carry out stocking production.

　　3. Sales model

　　The company mainly adopts the direct selling mode, and the downstream customers are mostly domestic large-scale well-known power battery and energy storage battery manufacturers. After long-term cooperation, a stable cooperative relationship has been formed.

　　The sales process mainly includes obtaining sample demand, technical exchange, sample certification at various stages, signing contracts, delivery, payment back and other links; Sample certification at each stage includes the production, delivery, evaluation, customer certification, improvement, specification/drawing signing and other processes of samples at different levels, such as laboratory level and production line level, so as to ensure that the whole process of products from performance to batch quality stability can meet customer needs. After the certification stage, the company signed a supply contract with customers for mass production, and tracked the delivery of goods and the recovery of payment. If the customer puts forward further requirements for the certified products, the company will directly sign a supply contract with the customer for mass production.

　　(3) the industry situation

　　1. The development stage, basic characteristics and main technical threshold of the industry.

　　(1) Industry development stage

　　The market demand for new energy vehicles continues to grow rapidly, and the power battery industry is booming, which drives the scale of the cathode material industry to increase rapidly. According to the statistics of China Automotive Power Battery Industry Innovation Alliance, the cumulative output of power batteries in China was 545.9GWh in 2022, up 148.5% year-on-year. According to the data of GGII, in 2022, the market shipment of cathode materials for lithium batteries in China was 1.9 million tons, up 68% year-on-year, of which the shipment of ternary materials was 640,000 tons, up 47% year-on-year. Market growth is mainly driven by domestic ternary power battery growth and overseas export demand. From 2017 to 2022, China’s ternary cathode material shipments continued to grow, with a compound growth rate of 43.28%.

　　(2) the basic characteristics of the industry

　　At present, the cathode material industry has the following basic characteristics:

　　① At present, Ferrous lithium phosphate and ternary cathode materials are the main technical routes of power batteries.

　　According to the statistics of China Automotive Power Battery Industry Innovation Alliance, the cumulative loading capacity of power batteries in China reached 294.6GWh in 2022, with a cumulative year-on-year increase of 90.7%. Among them, the cumulative loading capacity of ternary batteries is 110.4GWh, accounting for 37.5% of the total assembly vehicle, with a cumulative year-on-year increase of 48.6%; The cumulative loading capacity of lithium iron phosphate battery was 183.8GWh, accounting for 62.4% of the total vehicle, with a cumulative year-on-year increase of 130.2%.

　　Ternary cathode materials and Ferrous lithium phosphate, as the mainstream technical routes of power batteries at present, will develop vigorously in 2022 in terms of output, sales volume and loading capacity.

　　② The supply chain of raw materials is fragile and the price of raw materials fluctuates greatly.

　　The raw materials of cathode materials for lithium ion batteries are mainly lithium salts and precursors. While the new energy market is booming, the prices of raw materials such as lithium salt fluctuate greatly due to the imbalance between supply and demand. Take the battery-grade lithium carbonate quoted by Shanghai Nonferrous Metals Co., Ltd. as an example, the price including tax was less than 300,000 at the beginning of 2022, and the highest price including tax was close to 600,000 in November 2022. The sharp fluctuation of raw material prices has brought adverse effects to the sustained and healthy development of the whole industry.

　　③ The competition is fierce, and there is little difference in the share of head enterprises.

　　According to the statistical data of Hi-Tech Lithium Battery and Xinyi Lithium Battery, the market share of domestic ternary cathode material industry in 2018-2022 was 48%/50%/52%/55%/61% respectively, with an average annual increase of about 2-3 percentage points. Compared with other lithium battery materials, the competition in ternary cathode material industry is fierce, and the market share of head enterprises is small, which has not opened a big gap. The main reasons are as follows: First, the entry threshold of ternary cathode material industry is high, and there are few new entrants; Second, the head ternary materials enterprises have their own advantages and the market competition is fierce.

　　④ cathode material manufacturers have expanded their production, so they should be alert to the risk of overcapacity.

　　The vigorous development of new energy industry has attracted the attention of all forces and funds to the cathode material industry, and cathode material manufacturers have expanded their production. For the sub-sectors with serious homogenization of products, due to the lower technical threshold, they will face more intense competition.

　　(3) Main technical thresholds

　　(1) industry standard barriers

　　On December 10, 2021, the Ministry of Industry and Information Technology officially issued the Specification Conditions for Lithium-ion Battery Industry (2021 Edition) and the Management Measures for Announcement of Lithium-ion Battery Industry Specification (2021 Edition), which came into effect on December 20, 2021, and set strict requirements on the R&D capability, advanced technology, quality inspection and intelligent manufacturing capability of production enterprises. At the same time, it strengthened corporate social responsibility. Usually, it is difficult for industrial enterprises to meet the requirements of relevant industry norms in a short time through investment.

　　② Barriers to quality certification

　　Because the cathode material is one of the most important raw materials in power batteries, it has a great influence on the core performance and safety performance of power batteries. Considering the stability and safety of products, the certification and testing procedures of cathode materials for car companies and power battery companies are more complicated, which requires not only long-term product performance testing, but also detailed evaluation of the comprehensive supply capacity of manufacturers. The overall certification cycle time is generally about 1-2 years. At present, the domestic power battery market is highly concentrated. Power battery manufacturers have established long-term cooperative relations with cathode material manufacturers, and the cooperation is sticky. Once cathode material manufacturers enter the customer’s supplier system, they will not be easily replaced.

　　③ Technological barriers

　　The technology of ternary cathode materials is complex, the production process is strictly controlled, the research and development is difficult, the cycle is long, and the technology experience is important. All domestic manufacturers have formed their own technology, such as the selection of raw materials, the proportion of various materials, the application of auxiliary materials and the production process, which requires years of technology and experience accumulation. Technological barriers not only refer to higher R&D technical threshold, but also include finer production management and lower cost mass production level.

　　From the technical point of view, ternary cathode materials are mainly divided into primary particle large single crystal technology system and secondary particle aggregate technology system. Manufacturers with different technical routes have differences in sintering times, sintering furnace design, temperature control, doping coating elements and other production processes, and have formed their own technological barriers through long-term experience accumulation.

　　From the perspective of industry development, low-cobalt/cobalt-free NCM ternary materials with cost performance and high-nickel NCM ternary materials with energy density are the development trends of ternary cathode materials industry. In view of the scarcity of cobalt resources, high price and large fluctuation, decarbonization is the current mainstream trend. The development of low-cobalt/cobalt-free materials, including the selection of precursors, sintering process, doping and coating technology, determines the difference in cost performance and comprehensive competitiveness of materials. Compared with conventional ternary materials, the technical barriers to produce high-nickel ternary cathode materials are higher. The production of high-nickel ternary cathode materials not only needs technical modification such as doping and coating, but also needs calcination in oxygen atmosphere, which puts forward more stringent requirements for humidity control of production environment, corrosion resistance of equipment and automation level.

　　(4) production scale and capital barriers

　　Large-scale ternary material production enterprises have scale advantages in raw material procurement and production operation. At the same time, the market concentration of the power battery industry is high, and mainstream power battery manufacturers have higher requirements for the quality, quantity and timeliness of cathode material suppliers, so it is difficult for small enterprises to enter the qualified supplier system of lithium battery enterprises.

　　Ternary materials are capital-intensive industries. Ternary materials have high requirements for production environment and production equipment, and large capital investment is needed to build new production lines. In addition, the cost of purchasing raw materials accounts for a relatively high proportion in the production cost of ternary materials, and a large amount of liquidity is needed for daily business activities. New entrants to the industry face certain scale and financial barriers.

　　2. Analysis of the industry position of the company and its changes.

　　In 2009, the company completed the research, development and production of ternary cathode materials with large primary particles and single crystal of lithium nickel cobalt manganate at home and abroad earlier. After years of research, development and cultivation, the company has realized the industrial production and sales of ternary cathode materials of large single-crystal nickel cobalt lithium manganate covering a full range of medium nickel, medium high nickel, high nickel and ultra-high nickel, and is also a producer of lithium cobalt manganate, composite ternary and other varieties of cathode materials for lithium ion batteries. At present, the company has mastered the synthesis technology of one-step large single crystal Ni-Co-Mn ternary material, one-step large single crystal Ni-Mn binary material with cobalt-free layered structure, one-step high-voltage lithium cobaltate material, one-step polycrystalline Ni-Co-Mn ternary cathode material, one-step spinel composite modified material, one-step anode material doping technology, one-step large single crystal material with medium high nickel and low cobalt content, one-step large single crystal material with high nickel content, and one-step sodium ion battery cathode material.

　　According to the statistics of Xinyi Information, in 2022, the company’s ternary material output ranked seventh in the domestic market, with a market share of 7%; In 2022, the company’s output of large single crystal ternary materials ranked third in the domestic market, accounting for 17% of the corresponding output. In 2022, the company’s market application and promotion of sodium ion battery cathode materials progressed smoothly, and reached a comprehensive and in-depth cooperative relationship with domestic head battery customers, with a cumulative shipment of dozens of tons. With the continuous improvement of the company’s new product development and application in the field of high nickel and ultra-high nickel primary particle large single crystal ternary cathode materials and sodium ion battery cathode materials, the company will maintain strong competitiveness in the industry for a long time.

　　3. Development and future development trend of new technologies, new industries (300832), new formats and new models during the reporting period.

　　1. With policy support, consumer confidence will gradually recover, and the demand for new energy vehicles will be effectively boosted.

　　New energy vehicles are an important driving force for the automobile market and a key industry to stabilize the national industry. Therefore, in order to further expand the promotion scale of new energy vehicles, a series of policies have been issued at the national level to implement the project of strengthening the foundation by leading new energy vehicles. At the same time, the Party’s Report to the 20th CPC National Congress emphasized that it advocates green consumption and promotes the formation of green and low-carbon production methods and lifestyles. The Central Economic Work Conference held at the end of 2022 proposed to support consumption such as housing improvement, new energy vehicles and old-age services. With the effectiveness of various policies and measures, automobile consumption will continue to stabilize and recover, and the power battery market will also usher in a new round of development.

　　2. Determination of high nickel trend of ternary cathode materials

　　Under the background of mileage anxiety and charging anxiety of new energy vehicles, the improvement of battery energy density mainly starts from the upgrading of electrochemical performance and the innovation of physical system structure. According to the data of GGII, in 2022, in the shipping structure of ternary materials in China, the proportion of ternary materials with high nickel content of 8 series and above rose to the first place, accounting for over 40%. In addition, overseas markets mainly use high-nickel materials, and some domestic enterprises increase overseas supply and export, which also drives the shipment of high-nickel materials to increase. The properties of 8-series and above high-nickel ternary materials are fully improved, and at the same time, their preparation technology threshold is high, and the market access threshold is high. In the fierce market competition in the future, the research and development, production and preparation capabilities of 8-series and above high-nickel ternary materials have an important impact on the development of cathode material manufacturers.

　　3. Ternary cathode materials will remain one of the mainstream technical routes in the future.

　　For the downstream market, the cost performance of cathode materials is one of the important factors to measure the technical route selection. Since 2021, the installed capacity of Ferrous lithium phosphate has surpassed that of ternary cathode materials, mainly due to the technical breakthrough of lithium iron phosphate battery and the rising cost of ternary cathode materials due to the rising price of nickel and cobalt. Due to the determination of the high nickel trend of ternary cathode materials and the limited market space of consumer electronics, the demand for cobalt metal is reduced; In terms of nickel, with the continuous release of new production capacity, the supply continues to increase, so it is expected that the price of cobalt and nickel will stabilize, and it is expected that the following ternary materials with 8 series and above high nickel will have significant cost advantages, so ternary cathode materials, especially ternary materials with 8 series and above high nickel, will be one of the mainstream technical routes of power batteries in the future.

　　4. The comprehensive recycling of waste power batteries continues to increase.

　　With the popularization of electric vehicles, it is inevitable to deal with the waste power batteries. After the waste power battery is used step by step, the remaining part can be recycled because it contains precious metals. In the European market where the voice for new energy vehicles has been very high, specific targets and implementation paths have been set for the recovery rate of major metals such as lithium, nickel and cobalt, and the market development has been guided by legislative norms. China’s "Tenth Five-Year Plan for the Development of Circular Economy" puts forward that the development of circular economy is a major strategy in China, and the recycling of used power batteries is one of the key areas of action. Therefore, it is an important trend in the future to develop the recycling industry of waste power batteries, reduce the loss of precious metals and promote the sustainable development of resources and environment.

　　5. The supply chain of raw materials for lithium-ion batteries is fragile, which has a negative impact on the sustainable and healthy development of the new energy industry.

　　While the new energy industry is booming, the price of lithium salt, the main raw material of lithium ion batteries, is prone to violent fluctuations in the short term due to the imbalance between supply and demand, which is not conducive to the marketization and scale of new energy vehicles and energy storage industries. As the largest producer and user of lithium salt in the world, China’s lithium resource supply mainly depends on imports. With the increasing emphasis on the new energy industry in China, especially the huge demand for lithium resources brought by the increasing production, sales and penetration rate of upstream new energy vehicles, although the capital investment in both lithium mines and smelting ends continues to increase, due to the relative shortage of domestic lithium mines, the overall increase in the future is limited, and the fragile supply chain has caused concerns about the future sustainable development of the new energy industry.

　　6. The industrialization process of sodium ion battery is accelerated, and the market application and promotion are progressing smoothly.

　　While the new energy industry is booming, the imbalance between supply and demand of some raw materials for lithium-ion batteries has adversely affected the sustainable and healthy development of the industry. Sodium ion battery is obviously superior to lithium ion battery in low temperature performance, which is very suitable for all-weather and all-regional electric vehicle market demand. Most importantly, compared with lithium, sodium has more abundant reserves and lower price, and the supply chain of sodium ion battery raw materials is stable. On June 1, 2022, the National Development and Reform Commission and the National Energy Administration jointly issued the "Tenth Five-Year Plan for Renewable Energy Development", proposing to strengthen the research and development of high energy density energy storage technologies such as sodium ion batteries. From the industry practice, the head enterprises in the industry, including Contemporary Amperex Technology Co., Limited (300750), are also laying out sodium ion batteries with more advantages in cost and more stable electrochemical performance. Therefore, the sodium ion battery and upstream materials industry are expected to usher in rapid development opportunities.

　　(IV) Core technologies and R&D progress

　　1. Core technologies and their advanced features and changes during the reporting period.

　　Since its establishment, the company has focused on the research and development and production of cathode materials. In 2009, it completed the research and development and production of nickel-cobalt-lithium manganate ternary cathode materials with large single crystal particles at home and abroad earlier. The company has made some contributions to the technical route of domestic power battery industry in the technology of ternary cathode material with large primary particles and single crystal. At present, the global power battery market has formed a tripartite confrontation among China, Japan and South Korea. From the technical route and development direction, China’s power battery has a unique ternary cathode material system with large primary particles and single crystals, which enhances the market competitiveness.

　　The company has successfully developed and formed a series of core technologies with independent intellectual property rights, including the synthesis technology of one-time large single crystal Ni-Co-Mn ternary materials, the synthesis technology of large single crystal Ni-Mn binary materials with cobalt-free layered structure, the synthesis technology of high-voltage lithium cobaltate materials, the synthesis technology of polycrystalline Ni-Co-Mn ternary cathode materials, the synthesis technology of spinel structure composite modified materials, the doping technology of cathode materials, the surface modification technology of cathode materials, and the synthesis technology of sodium ion batteries.

　　In the field of cathode materials for sodium ion batteries, after the accumulation of different projects and continuous running-in with customer product platforms, the company has formed a number of core technologies such as multi-element synergistic doping technology, crystal structure control technology, low pH value and low free sodium control technology, morphology size and particle size control technology, which can effectively improve the structural stability and air stability of cathode materials for sodium ion batteries, and improve the high and low temperature performance, cycle stability and rate performance of sodium ion batteries. For the above-mentioned core technologies, as of the disclosure date of this report, the company has submitted nine patent applications related to cathode materials of sodium ion batteries, forming a preliminary patent layout.

　　Relying on the above-mentioned core technology, the cathode material of sodium ion battery developed by the company has the characteristics of high pressure solid density, high capacity, low pH value and low free sodium. High voltage solid density and high capacity are helpful to improve the energy density of the battery; Low pH value and low free sodium can effectively improve the air stability of materials and the stability of battery slurry, thus improving the overall stability and consistency of the battery and improving the defect of gas generation and bulging of the battery. The related performance indexes of the cathode materials of layered sodium oxide ion batteries produced by the company are better than the market average, among which the specific capacity and first efficiency are higher than the market average, reflecting the higher energy density of the corresponding batteries; The contents of pH value, free sodium and nickel are lower than the market average level, which reflects that the battery produced correspondingly has better integrity and consistency and lower cost. The excellent performance of the company’s products has been recognized by mainstream customers in the downstream.

　　Iii. Analysis of core competitiveness during the reporting period

　　(A) analysis of core competitiveness

　　1. The first-Mover advantage and perfect product layout of NCM cathode material synthesis technology with large single crystal particles.

　　The conventional ternary cathode material of secondary particle aggregate is composed of many small single crystal particles, and the secondary particles are easy to crack and break during the cycle, which shortens the cycle life of the battery. The secondary particles are easy to break in the cold pressing process of the pole piece, which makes the performance of the battery deteriorate. The ternary cathode material with large primary particles and single crystal can avoid the above problems well. After compaction and high temperature cycling, the material can obtain better high temperature cycling stability, structural stability and high temperature resistance, so it has better safety performance. Ternary cathode materials with large primary particles and single crystals are mainly used in the domestic market and are one of the mainstream choices in the domestic power battery industry.

　　In 2009, the company launched the first generation of large single crystal NCM523 products in the whole industry earlier, and it was applied in batches in new energy vehicles in 2014. The company’s medium nickel 5 series single crystal products have been continuously and stably exported for many years, and have been widely recognized in the downstream market by virtue of their stable and reliable technical performance. Besides being mature and applied in foreign high-end models, they are also applied in batches in domestic mainstream models.

　　In 2018, the company successively launched the ternary cathode material of medium-high-nickel and low-cobalt primary particle large single crystal and the ternary cathode material of high-nickel primary particle large single crystal. At present, the medium-high-nickel 6-series single crystal products have a high cost performance advantage in high-voltage scenarios, accounting for an increasing proportion of the main business income, while the high-nickel 8-series single crystal products continue to increase steadily.

　　In terms of ultra-high nickel 9 series single crystal materials, tons of samples were sent to some customers in 2021, and the energy density and high-temperature storage performance of the products were superior to those of competitors of the same type. During the reporting period, more than 10 tons of products were shipped. At present, the company has the mass production capacity of ternary cathode materials with medium nickel, medium high nickel, high nickel and ultra-high nickel, forming a perfect product layout and promoting the long-term sustainable development of the company’s ternary cathode materials business.

　　2. The first-Mover advantage of the cathode material of sodium ion battery and the leading advantage of taking the lead in realizing ten-ton mass production.

　　In 2016, the company began to research and develop products related to the cathode materials of sodium ion batteries. With the rapid increase in the market price of lithium salt since 2021, the problem of the stability of lithium salt supply has become more and more prominent. The cathode materials of sodium ion batteries have gradually attracted market attention due to their rich reserves, high cost performance and safety performance, and the company has correspondingly accelerated the research and development process of the cathode materials of sodium ion batteries.

　　The accumulation of large single crystal technology system in the field of ternary cathode materials is an important guarantee for the rapid development of cathode materials for sodium ion batteries and the recognition of product performance by customers. The cathode material of single crystal sodium ion battery produced by the company through the large single crystal technology system has complete material structure and good processability, and there will be no particle fragmentation in the cycle process, which effectively reduces the situation of new interface caused by particle fragmentation and effectively improves the high-temperature and high-voltage cycle performance of sodium ion battery, especially the high-temperature stability.

　　Up to now, the company has mastered many core technologies such as multi-element synergistic doping, crystal structure control, low pH value and low free sodium control, morphology size and particle size control, and the patent layout guarantee technology is self-controllable; At the same time, combined with the downstream application scenarios, the company targeted the development of cathode materials for sodium ion batteries, and the performance of related products matched the needs of customers. During the reporting period, the market promotion and application progressed smoothly, and the company has achieved sales of tens of tons, fully guaranteeing the company’s leading edge in the positive electrode material market of sodium ion batteries.

　　3. Brand and quality advantages

　　Since its establishment, the company has focused on independent innovation and R&D, and created a brand image. By establishing a strict brand and quality management system and continuous investment in technology R&D, it has gradually established a long-term and stable cooperative relationship with many high-quality battery manufacturers in the industry, and established its own brand position through a number of international and domestic related qualification certifications.

　　On October 26, 2016, the company passed the quality management system standard "ISO/TS16949:2009", and the scope of certification was the design and manufacture of lithium-ion cathode materials. In 2018, it passed the edition change audit of "IATF16949:2016" to ensure that the company’s new product development and product quality can continuously meet the relevant standards of the quality management system and the needs of downstream customers.

　　The company always adheres to the product quality as the core, strictly abides by the quality management procedures such as Product Advance Planning Control Procedure and 5M1E Change Control Procedure, and implements the whole process guarantee for new product development and mass production. Since 2009, the quality and yield of the company’s cathode materials are at a high level, which has been recognized by leading domestic battery manufacturers downstream. During the reporting period, the company won excellent supplier awards from many customers.

　　4. Advantages of high-quality customer resources

　　The company has always adopted the competitive strategy of concentrating limited enterprise resources to cultivate and maintain large customers, which can form scale operation to gain cost advantage, share information in time to promote product technology innovation to meet customer needs, form a stable source of sales orders, produce market radiation effect and increase market share. The long-term recognition of high-quality large customers also enhances the company’s reputation in the industry, and can bring other high-quality new customers to the company while expanding its production capacity and maintain a strong competitive advantage.

　　For a long time, the company has been guided by the needs of downstream and end customers, and continues to independently research and develop cathode materials, and constantly improve the competitiveness of products on the basis of ensuring excellent cycle stability and safety performance of materials.

　　Since 2004, the company has established a good reputation in the industry with its reliable product quality, and has successively entered the supply chain of well-known domestic lithium-ion battery manufacturers, and formed a long-term and stable cooperative relationship. Through long-term close cooperation, the company has become an important supplier of cathode materials for domestic battery manufacturers such as Contemporary Amperex Technology Co., Limited, Funeng Technology, ATL, Polyfluoride (002407), Tianjin Lishen, Zhuhai Guanyu and Weihong Power.

　　6. Advantages of sustainable development

　　As a subsidiary company of central enterprises, the company actively serves the national strategy by operating business, and pays attention to social responsibility while creating economic value. By participating in the company Red Star Electronics, the company laid out the waste lithium-ion battery and material recycling industry, and strengthened the ability to control the cost of raw materials such as ternary precursors. As of the end of the reporting period, the company holds 34% equity of Red Star Electronics. Red Star Electronics uses waste lithium-ion batteries and secondary biomass to extract and recover valuable materials such as usable lithium and cobalt, and converts its production into raw materials used in the production of ternary precursors, lithium carbonate and other companies. The industrial layout of waste lithium-ion batteries and materials recycling is an important way for the company to accelerate the integration of upstream industries, at the same time, it can effectively reduce the loss of precious metals and promote the sustainable development of resources and environment.

　　At the same time, the company continues to promote the integration of sustainable development and daily production and operation. The company has two production bases, which are located in Guiyang City, Guizhou Province and Yilong New District, Southwest Guizhou Province.

The company has made important contributions to rural revitalization and common prosperity through industry guidance, employment assistance and radiation, and was selected as an excellent practice case of rural revitalization of listed companies promulgated by China Association of Listed Companies.

　　(II) Events that have seriously affected the core competitiveness of the company during the reporting period, impact analysis and countermeasures.

　　

　　Fourth, risk factors

　　(A) Not yet profitable risk

　　(2) Risk of sharp decline in performance or loss

　　(C) core competitiveness risks

　　1, the risk of technology update iteration

　　There are many technical routes for cathode materials of lithium-ion batteries. At present, cathode materials of lithium-ion batteries which are widely used in the market include lithium cobaltate, lithium manganate, Ferrous lithium phosphate and ternary cathode materials (including NCM and NCA). With the expansion of the production and sales of new energy vehicles, the demand for cruising range and energy density has increased, and ternary cathode materials have developed rapidly in recent years.

　　Since the second half of 2021, due to the superposition of factors such as declining subsidies, rising energy storage market and rising nickel and cobalt raw materials, the cost-effective advantage of lithium iron phosphate batteries has been highlighted, and the installed capacity of lithium iron phosphate batteries has exceeded ternary batteries for many months. In addition, with the rapid increase in the market price of lithium salt since 2021, sodium ion batteries have gradually attracted market attention because of their low cost, good electrochemical performance and safety.

　　If the mainstream technical route of power batteries for new energy vehicles is updated and iterated in the future, and the installed capacity of ternary cathode materials for power batteries continues to decline, it will no longer become one of the mainstream cathode materials for power batteries, then the market demand for ternary cathode materials may face the risk of substitution. If the company fails to develop and launch new cathode materials that meet the market demand in a timely and effective manner, it will adversely affect the company’s competitive advantage and profitability.

　　2, new technology and new product development risk

　　At present, the company’s main research and development directions include the development and basic research of low-cost ternary precursors, sodium ion battery cathode materials, primary particle large single crystal ternary materials, cobalt-free nickel-manganese binary materials, high-voltage lithium cobaltate and other materials. Due to the technology-intensive nature of the cathode material industry, new technologies and corresponding new products are at risk of R&D failure. The above-mentioned research projects of the company focus on reducing material costs and new cathode materials, and there are risks that the research and development results of new technologies and corresponding new products fail to pass customer certification, fail to meet customer needs, and the relevant performance indicators are not as expected. Once the research and development of new technologies and corresponding new products falls short of expectations, or there is a breakthrough in the core technology of the company’s industry and the company can’t master the relevant technologies in time, it will have a certain adverse impact on the market competitiveness and profitability of the company’s products.

　　At present, the sodium ion battery market as a whole is in the early stage of industrialization. At present, the company’s sodium ion battery cathode materials have achieved sales of dozens of tons. However, if the industrialization verification of sodium ion battery cathode materials fails to meet expectations and customers’ needs, it will have a certain adverse impact on the market competitiveness of the company’s products and the realization of the company’s development planning objectives.

　　3. Risk of loss of key technologies

　　At present, The company has mastered a series of independent knowledge, such as the synthesis technology of one-time large single crystal Ni-Co-Mn ternary material, large single crystal Co-free layered structure Ni-Mn binary material, high-voltage lithium cobaltate material, polycrystalline Ni-Co-Mn ternary cathode material, spinel structure composite modified material, cathode material doping technology, cathode material surface modification technology, medium-high Ni-Low Co one-time large single crystal material, high Ni one-time large single crystal material and sodium ion battery cathode material synthesis technology. The company’s market competitiveness and profitability depend on the above-mentioned long-term accumulated core technologies. In the current increasingly fierce market competition, if there is a loss of key technologies, it may affect the company’s market competitiveness and profitability to a certain extent, thus adversely affecting the company’s future operating performance.

　　(4) Operational risks

　　1. The fluctuation of raw material prices and the risk of fragile lithium salt supply chain.

　　The main raw materials needed for the company’s production and operation include ternary precursors, lithium carbonate, lithium hydroxide and cobaltosic oxide, and the corresponding metal raw materials include lithium, cobalt, nickel and manganese. Affected by the macroeconomic situation, changes in the supply and demand pattern of the industry and unexpected events, the market prices of major metal raw materials such as lithium, cobalt and nickel have fluctuated greatly in recent years. In addition, China is the largest producer and user of lithium salt in the world, and the supply of lithium resources mainly depends on imports. With the increasing emphasis on the new energy industry in China, especially the huge demand for lithium resources brought by the increasing production, sales and penetration rate of upstream new energy vehicles, although the capital investment in both lithium mines and smelting ends continues to increase, due to the relative shortage of domestic lithium mines, the overall increase in the future is limited, and the fragile supply chain has caused concerns about the future sustainable development of the new energy industry.

　　If the market price fluctuation of major raw materials leads to a large deviation between the procurement cost of raw materials and the market price at the time of sales pricing, or the production scale of the company expands rapidly, and the supply of lithium salt is intensified, so that the inventory lithium salt can not meet the production demand and cannot be purchased in time, or the inventory is impaired during the downward period of lithium salt price, which will lead to a large fluctuation in the profitability of the company’s products and affect the stability of the company’s supply chain, thus adversely affecting the company’s production, operation and profitability.

　　2. Risk of fluctuation of sales price

　　According to the industry practice, the company’s main products adopt the cost-plus pricing model of "main raw material cost+processing price". During the reporting period, the market prices of the upstream main raw materials of the company, such as ternary precursor, cobaltosic oxide and lithium carbonate, fluctuated greatly, resulting in the sales prices of the company’s main products also fluctuated greatly.

　　In view of the fact that the purchase time of raw materials in the actual cost of the company is earlier than the product sales pricing time due to the factors such as production cycle, safe inventory and scale benefit of centralized procurement, the average price of raw materials in the actual cost may deviate from the market price at the sales pricing time. If the market price of raw materials falls sharply or fluctuates in a certain period of time, which leads to the deviation between the average price of raw materials in the actual cost and the market price at the time of sales pricing, the company has the risk of being unable to pass on the raw material procurement cost to the downstream, thus having a certain adverse impact on the company’s profitability.

　　3. Risk of idle new production capacity

　　With the continuous production of projects under construction, the overall production capacity of cathode materials has been improved to some extent. If the future market development fails to meet the company’s expectations, the market environment changes significantly, or the company’s market development fails to meet the expectations, the company will not be able to achieve the expected economic benefits according to the established plan, thus facing the risk that the capacity utilization rate will drop after the expansion, the new capacity will not be digested and the related production lines will be impaired.

　　4. Risk of high concentration of downstream customers.

　　The company’s downstream lithium battery industry has a high market concentration. According to the survey data of GGII, from 2018 to 2022, the total market share of the top five power battery companies in China exceeded 80%. Influenced by the high concentration of the downstream market and the company’s strategy of adhering to the core high-quality big customers, in 2022, the company’s sales amount to the top five customers accounted for more than 90% of the current operating income, which was at a high level. There is a risk of high concentration of downstream customers in the company. In the future, if major customers reduce their purchases from the company due to unfavorable operation or adjust the scope of suppliers, or fierce competition leads to the loss of major customers, it will have an impact on the company’s sales scale, repayment speed and gross profit margin, thus adversely affecting the company’s operation.

　　5. Risk of product quality problems

　　The final application direction of ternary cathode materials produced by the company is mainly in the fields of new energy vehicles. New energy vehicles have higher requirements for the safety of power batteries, and all industrial chain enterprises need to ensure that their products continuously meet the relevant standards of quality management system in terms of technical performance, quality reliability and consistency. The quality of cathode materials for lithium-ion batteries is easily affected by the stability of production process, which has the characteristics of high technical difficulty and complex process. The downstream customers of the company are well-known domestic lithium battery manufacturers, and usually have high requirements on product quality. Therefore, strict control of product quality is an important guarantee for the sustainable and healthy development of ternary cathode materials enterprises. If the company has serious product quality problems in the future, which will lead to a large number of returns, it will probably affect the market sales of products and lead to the loss of major customers, thus adversely affecting the company’s operating performance.

　　(V) Financial risks

　　1. The risk that the gross profit margin of product sales fluctuates greatly

　　According to the industry practice, the products of the company are priced by the cost-plus model of "main raw material cost+processing price", in which the "processing price" is basically stable, and the "main raw material cost" is mainly determined by both parties through consultation with reference to the market price of raw materials in the previous month at the point of sale. In view of the fact that the purchasing time of raw materials in the company’s actual cost is influenced by factors such as safety inventory and scale benefit of centralized procurement, which is earlier than the pricing time of products, the matching between the average purchasing price of raw materials in the cost and the market price of raw materials at the point of sales pricing is lagging behind. Affected by the market price fluctuation of main raw materials during the reporting period, the gross profit margin of the company’s main business fluctuated greatly due to the lag in the matching of product unit cost and "main raw material cost" in sales pricing.

　　At the same time, in view of the difference in gross profit margin among different types of ternary cathode materials, the sales structure of ternary materials with high nickel, medium high nickel and medium nickel in different periods will also have an impact on the overall gross profit margin of ternary cathode materials. In this context, if the market price of raw materials falls sharply or fluctuates in a certain period, resulting in a significant deviation between the average price fluctuation trend of raw materials in actual cost and the market price of raw materials in last month, the unit cost of raw materials drops significantly below the unit selling price, or the production and sales volume drop significantly due to the downstream demand shocks, the product structure of the company has not been effectively improved, or the company’s procurement cost of ternary cathode materials is still relatively high due to the direct layout of ternary precursors, then the company has the risk of large fluctuation in gross profit margin.

　　2, the risk of high asset-liability ratio

　　At the end of 2022, the company’s asset-liability ratio was 63.07%, which was at a high level. On the one hand, the high asset-liability ratio makes the company face a certain risk of debt; on the other hand, with the continuous expansion of the company’s production and operation scale, the capital demand continues to increase, which also brings certain pressure to the company’s new debt financing.

　　3. Higher accounts receivable may increase the risk of bad debt losses.

　　At the end of 2022, the balance of the company’s accounts receivable was 1,686,741,800 yuan, accounting for 12.10% of the current operating income, respectively. The company’s accounts receivable amount and the proportion of the current operating income were relatively high. If the company’s accounts receivable amount increases further in the future, and individual customers delay or refuse to pay due to their own factors such as the deterioration of business conditions, the company will face the risks of prolonged accounts receivable age, decreased collection rate, increased bad debt provision, and the need to make provision for bad debts for some customers’ accounts receivable, which will have a certain adverse impact on the company’s profitability.

　　4. Risks such as large inventory amount and falling prices.

　　In 2022, the book value of the company’s inventory was 1,825,297,400 yuan, accounting for 16.49% of the total assets at the end of the period, and the inventory amount was relatively high. Higher inventory takes up a large part of the company’s working capital, which may lead to a certain risk of inventory backlog. At the same time, if the market environment changes adversely, there may be a risk of inventory depreciation in future operations.

　　(VI) Industry risks

　　Downstream industry demand fluctuation risk

　　NCM ternary cathode material, the company’s core product, is currently mainly used in the domestic new energy vehicle power battery market. Policy changes in the new energy automobile industry will affect the changes in the production and sales volume of the new energy automobile industry. As ternary cathode materials account for a relatively large proportion in the total cost of power batteries and are the key components of power batteries, the policy changes in the new energy automobile industry will have an impact on the market demand for ternary materials.

　　In the future, if the global economic situation and downstream industry demand fluctuate significantly or continuously, it will adversely affect the company’s production, operation and profitability.

　　(VII) Macro-environmental risks

　　The development of the ternary cathode material industry in which the company is located is closely related to the development status and development trend of the downstream new energy vehicles, consumer electronics and energy storage industries, and there is still some uncertainty in the current global macroeconomic situation. If the macro-economic environment undergoes major adverse changes, the economy enters a downward cycle, or the market demand factors affecting downstream new energy vehicles, consumer electronics and energy storage industries change significantly, it may adversely affect the company’s operating performance.

　　(8) Risks related to depositary receipts

　　(9) Other major risks.

　　This newspaper (reporter Guo Meihong)"I’m sorry, I’ll reply you later. I just received two cases, both of which are urgent. " Before leaving work, Shang Yanjun, a forensic doctor of Luan County Procuratorate in Hebei Province, sent a text message to the reporter. Fourteen years ago, because of her "super professional identity" with forensic doctors, she "switched careers" halfway to join the professional group of procuratorial forensic doctors.

　　Forensic medicine, a profession dealing with injury and death, is full of mystery to ordinary people.

　　Procuratorial forensic doctors are a special team in the procuratorate. Their battlefields are autopsy room and medical equipment room. In addition to restoring the truth of casualties by meticulous and exquisite professional skills like ordinary forensic doctors, they also undertake a special task-review and supervision, that is, they have to "review and check" the casualty identification in criminal cases; They should be involved in the identification of casualties in detention centers, detention centers and prisons.

　　Some people are released on bail for coronary heart disease by taking atropine, some people suddenly fall to the ground and die when being questioned, some people deliberately identify minor injuries as minor injuries, and write serious injuries as minor injuries … All these require them to hold on to the knife and pencil of justice, expose the false appearance with excellent professional accumulation and professional ethics, and restore the truth.

　　Their paper appraisal often determines the nature of a person’s crime and non-crime, misdemeanor and felony, and involves the future direction of a person or even a family. Therefore, for each appraisal, they are like walking on thin ice, because a slight mistake may lead to unjust, false and wrong cases.

　　"disobedient son" kills father

　　Why only sentenced to three years?

　　A few years ago, a death case occurred in Dongxia Town, Yunxiao County, Fujian Province, in which Zhou injured his father Zhou Moushan. After the case happened, the news media made a lot of reports on the incident of "disobedient son killing father". For a time, public opinion accused his son of "going against the road and annihilating human nature". It seems that it is not enough for the people to be angry if Zhou is not shot. The case was submitted to Zhangzhou City Procuratorate, and forensic doctor Liu Longqing (who was awarded the first class merit by the Supreme People’s Procuratorate and won the title of "Watching Justice-Top Ten Prosecutors Favorite by the Masses") examined the injuries of the deceased, and without saying anything, he and the case handlers drove more than 100 kilometers to the crime scene. Liu Longqing frowned when he learned that the body had been cremated.

　　The original identification was that the deceased died of cerebral hemorrhage, but the autopsy photos could not show where the bleeding point was. Liu Longqing talked with relatives and neighbors of the deceased many times. When he learned from the relatives of the deceased that the deceased had a history of heart disease, he seemed to learn something from it.

　　After carefully reviewing the inspection report and combining the condition of the deceased before his death, Liu Longqing boldly proposed that the injury behavior of his son Zhou was not the direct cause of his father’s death.

　　He further explained that the deceased had a 4cm frustration laceration on the forehead. The original identification thought that the deceased died of severe craniocerebral injury. After examination, it was found that there was no fracture in the skull and skull base, no bleeding in the epidural, subdural and subarachnoid space, and no injury and bleeding in the brain and brain stem. Therefore, it was considered that there was insufficient basis for the death of craniocerebral injury. Combined with Zhou’s severe coronary heart disease before his death, he suggested that he died of a heart attack caused by emotional excitement and forehead trauma (minor injuries) after a fierce quarrel with his son.

　　"Human life, forensic examination of the body, is actually a dialogue between the living and the dead. What the body tells you, the forensic doctor will pass it on to the judicial personnel through the expert opinion. The process of identification is not that the forensic doctor is talking, but that the body is talking. If forensic doctors can’t maintain their independence and scientificity, but succumb to public opinion or agree with empiricism, it is not only an embarrassment to the profession, but also a trampling on judicial justice. " Liu Longqing said.

　　Finally, according to Liu Longqing’s appraisal opinion, the court of first instance sentenced his son Zhou to three years’ imprisonment for intentional injury causing minor injuries. The murder case that caused a lot of noise together was handled impartially because of Liu Longqing’s meticulous review.

　　Sudden death in interrogation room

　　In fact, it is not "complicated"

　　Jin Yankui of the Technical Information Research Center of the Supreme People’s Procuratorate has been a forensic doctor for 18 years. Most of the casualties he intervened in occurred in the supervision places, among which there were many cases of conflicts between prisoners or deaths caused by their own diseases. He said, after all, there are fewer people extorting confessions by torture now, unlike when management was not standardized in earlier years.

　　However, casualties in prisons or detention centers are easy to arouse suspicion from the outside world, so they, as professional forensic doctors in legal supervision departments, will intervene in the appraisal at the first time. "The prison administration said that the prisoner died of illness, but most of the family members did not recognize it, saying that it was healthy when he entered. You said it was illness, I don’t believe it. This requires us to inspect the forensic identification of how to die. "

　　Three years ago, a suspect died in a police detention room in a city in Hebei Province. The party was a female employee of a company, who claimed that she could get the land at a cheap price. Someone gave her more than 200,000 yuan, but after waiting for a long time, she didn’t see her take the land, so she called the police. The public security police suspected that she had committed fraud and took her to the detention room. She was interrogated from 8 pm to 11 pm. I had to take photos at the end of the interrogation, but I didn’t expect her to suddenly fall to the ground (there was a monitoring display).

　　No one hit her, how could she suddenly fall to the ground? What’s the problem? The police were in a hurry and quickly moved her to the soft sofa in the opposite room (but there was no monitoring in this room) and let her lie down for a while. A few minutes later, the suspect died.

　　Sick of death? Was tortured to death? In order to find out the cause of death of the suspect, the local prosecutor later entrusted the forensic identification of the Supreme Inspection Technology Center. Jin Yankui participated in the autopsy all the time, and he concluded that the deceased died of pulmonary embolism. "She is not too old, about 40 years old, but she is very fat and has high blood lipids. Sitting for a long time leads to venous thrombosis in the lower limbs and enters the pulmonary artery, causing blockage."

　　Yan Yankui introduced that once pulmonary embolism occurs, it can cause death in a few minutes. In fact, the police officers who questioned her had already called 120 emergency calls, but it was too late when 120 came. It was particularly difficult to rescue this disease, and the survival rate was about 50%.

　　"Can’t this kind of identification be done by the public security forensic doctor himself?"

　　"Technically, can do it. But in terms of identity, they can’t. Why? As a party, the public security organ makes its own appraisal. How can ordinary people take it? As a legal supervision department, procuratorial organs are also involved in cases. "

　　Jin Yankui said that many sudden deaths in supervision places are related to pulmonary artery thrombosis.

　　A similar case occurred in a prison a few years ago, and Jin Yankui participated in the autopsy. After he and his colleagues dissected the body, they found that all organs of the deceased were not sick, and the conclusion was also pulmonary embolism.

　　Dig up false medical records

　　Technical evidence review is the main work of forensic doctors in the procuratorate, which improves the quality of cases again and again in the process of examining and analyzing doubts. Lv Pin, a forensic doctor of Tangshan Procuratorate, Hebei Province, once encountered a medical record fraud case.

　　Zhang was injured in the head with a beer bottle and bit his left thumb. He went to several hospitals successively, and was mainly diagnosed as an open fracture of the left thumb, a traumatic crown fracture of the second right tooth and a traumatic loss of the third right tooth. The forensic doctor of the local public security organ asked the experts of stomatology and hand surgery for consultation, and issued an appraisal opinion on minor injuries. Ren refused to accept this appraisal, petitioned many times and asked for re-appraisal. An appraisal institute in Beijing issued a minor injury appraisal opinion based on Zhang’s absence of the third right upper tooth, crown fracture of the second right upper tooth and dysfunction of the left thumb. The public security organ accepted this opinion, took compulsory measures of criminal detention against Ren, and requested approval for arrest.

　　After the procuratorate approved the arrest, Ren’s family refused to accept it and kept petitioning. When the case entered the stage of review and prosecution, the Public Prosecution Division entrusted the Tangshan Procuratorate to review the technical evidence of Zhang’s injury and make a composite appraisal if necessary.

　　After accepting the case, Lv Pin carefully examined the outpatient and inpatient medical records and criminal investigation files submitted for trial, and asked the case-handling department to retrieve Zhang’s left hand X-ray film, dental film and injury photos the next day after the injury. The results showed that Zhang’s injury photos showed that Zhang’s upper lip was not damaged, and the third tooth in the upper right was missing, but the alveolar fossa was flat, which was inconsistent with the rehabilitation characteristics of "blood clot in alveolar fossa" recorded in outpatient medical records. Moreover, the dental reading film showed that there was no alveolar fossa in the third tooth in the upper right, and the alveolar bone was absorbed. According to the above situation, the third tooth on Zhang’s upper right should fall off before injury.

　　In order to further find out the truth, Lv Pin, after communicating with the Public Prosecution Section of the local procuratorate, decided to investigate Yang, a stomatologist in a hospital, and recheck the function of Zhang’s left thumb.

　　In the face of Lv Pin’s professional inquiry and a large amount of evidence, doctor Yang admitted that he had forged the outpatient medical records of stomatology after accepting Zhang’s benefits. This made the investigators of the public security organs particularly surprised, because when Ren petitioned, they also conducted many investigations on Yang, all of which were fruitless.

　　Later, Lv Pin examined the function of the victim Zhang’s left thumb, and found that the distal segment of his left thumb healed well, and the movement of his left thumb was OK. Finally, according to Zhang’s injury, Lv Pin issued a minor injury appraisal opinion, and the procuratorate made a decision not to prosecute Ren according to law. The doctor Yang and the victim Zhang were sentenced for perjury and false accusation respectively.

　　medical tangle

　　Can be "clarified" by identification.

　　In recent years, medical disputes are increasing day by day, and the relationship between doctors and patients is becoming increasingly tense. In order to deal with patient complaints and medical disputes, health departments, hospitals and related medical staff have spent a lot of time and energy. However, for a long time, due to the limited identification technology, it was difficult to find out the cause of the accident. In order to resolve the contradiction as soon as possible, the mediation result was often compensated by the hospital. Over time, the embarrassing situation of "making a big fuss and making a small loss" was formed. On the one hand, it increases the economic burden of medical units and the psychological pressure of medical staff, and reduces the reputation and image of medical units and medical staff in society. On the other hand, the mutual compromise between doctors and patients sometimes leads to the failure to effectively protect the interests of patients.

　　How to turn this "confused account" of medical disputes into a clear account? Liu Longqing introduced that the technical center of the Procuratorate of Zhangzhou City, Fujian Province, where he is located, extended its business to the identification of injuries in medical disputes very early.

　　The cause was an "illegal medical practice case". At that time, a lying-in woman fell down because of breast abscess acupuncture, and was taken to the hospital for emergency treatment. Three days later, the lying-in woman died after being rescued. Acupuncture practitioners are investigated for criminal responsibility for illegal medical practice, but is the hospital responsible? The patient is arguing with the hospital. Liu Longqing’s autopsy found that the whole pericardium of the deceased was full of blood, and the heart had a rupture, which was caused by pericardial tamponade. "From the patient’s physical examination data, the hospital should consider that it is caused by pericardial blockage."

　　Based on Liu Longqing’s appraisal conclusion, the hospital compensated the maternal family, and the dispute between the two sides subsided.

　　The handling of the case made Liu Longqing realize that establishing a perfect and smooth medical appraisal system is the key to resolving the contradiction between doctors and patients. The local health bureau decided to invite Liu Longqing to join the medical dispute mediation Committee as an expert. Liu Longqing agreed without hesitation. Of course, he knows that this is a "hot potato". If it is not handled well, he may be involved in contradictions, but he knows better that many people will benefit from rebuilding a harmonious doctor-patient relationship and safeguarding the interests of doctors and patients and the order of medical services.

　　Use evidence and logic to draw conclusions, avoid being interfered by public opinion, prejudice and power, remove false images from complicated appearances and find the truth. This is the direction and goal that prosecutors and forensic doctors all over the country have been striving for.

　　"Forensic work is like a one-man show without applause. At the time of judicial reform, we still cling to procuratorial technology." Fourteen years later, when she mentioned the original "career change", Shang Yanjun said that she still had no regrets.

　　CCTV News:Among medical workers, there is such a special and important group, that is, interventional doctors called "lead-clad people". In the interventional department, almost all operations should be completed under the guidance of X-rays. In order to prevent the damage caused by radiation, they have to wear a set of lead protective clothing weighing more than 20 kilograms during the whole operation. Today we will follow the reporter’s camera and approach this group together.

　　Wu Anle, Director of Interventional Diagnosis and Treatment Center of Ningbo First Hospital, Zhejiang Province:This lead coat weighs about 20 Jin, which used to be heavier. Now it is made of better material and much lighter. This is a lead apron and this is a lead coat. Do a good job of protection.

　　After wearing lead clothes and cleaning hands, Wu Anle walked into the operating room at two o’clock in the afternoon. A patient with liver cancer needs interventional therapy.

　　Wu Anle told reporters that he had about 40 surgeries every month, and his hands and arms were exposed to high-intensity X-rays for a long time, so he left many scars.

　　Wu Anle, Director of Interventional Diagnosis and Treatment Center of Ningbo First Hospital:We sometimes put liver drainage on patients, and our hands are under radiation, and our own hands can see them, just like mine. If you wear lead gloves, your hand sensitivity will be affected.

　　In the operating room of interventional radiology department in xuanwu hospital, Capital Medical University, Jiao Liqun, director of radiology department, and his assistants are performing carotid stenting for patients. During the operation, Jiao Liqun needs to go in and out of the operating room several times for internal and external linkage and observation to ensure the best effect of interventional therapy. At the moment, the outdoor temperature is close to 40 degrees. Although there is enough air conditioning in the operating room, the surgical gown under the lead suit is already soaked.

　　Jiao Liqun, Director of Interventional Radiology Department of xuanwu hospital, Capital Medical University:It’s really tiring to carry a lead suit weighing dozens of pounds for several hours, and now with the development of interventional technology and materials, more and more diseases begin to tend to be interventional surgery, and the proportion of operations has decreased, so the workload of interventional doctors is greater and the intensity is greater.
