Mystery under the steering wheel (1): Interpretation of power steering system

  [Technology] Cars have become an indispensable part of our lives. The combination of steering wheel+shift lever+pedal seems to have become a natural way to control cars, but their respective mechanisms are rarely understood. Take the steering wheel in our hands as an example, the majority of riders are still vague about the common concepts of various steering systems, such as "the difference with hydraulic power" and "what is the variable power", and so on. Below, we will systematically introduce various common steering systems, answer these questions, and discuss the mysteries and mysteries of various steering systems with you.

 Home of the car

  Because of the long space, this paper introduces our most common system now, interprets "where does the power come from" and introduces the classification of power steering system.

  Power steering, as its name implies, is to resist steering resistance by increasing external force, so that drivers can complete steering with less force. It is also called power steering. It was originally designed to make some large vehicles with heavy weight operate more easily, but now it has become very popular. It makes driving easier and easier, and makes vehicles more agile and improves safety to some extent. Power steering can be divided into two categories according to the different sources of power-hydraulic power and electric power.

  The origin of hydraulic power steering can be traced back to February, 1902. Frederick W. Lanchester of Britain invented "Cause the steering mechanism to be actuated by hydraulic power", that is, the hydraulic driving steering mechanism. After that, inventors in the United States and Canada successively registered patents for similar inventions. In automobile production, the commercial production of hydraulic power steering system was first realized, and it was named Hydraguide hydraulic steering system, and it was installed on Chrysler’s sixth generation Imperial in 1951. With the development of technology, the steering system with electronic pump instead of mechanical pump appears, so the current hydraulic power is mainly divided into mechanical hydraulic power and electronic hydraulic power. In addition, the electronic servo hydraulic power steering system is derived from the mechanical hydraulic power.

  Let’s look at the main principle of mechanical hydraulic power steering, which is based on mechanical rack-and-pinion steering mechanism, and adds a whole set of hydraulic system, including liquid storage tank, hydraulic booster pump, mechanical valve connected with steering column, hydraulic cylinder on steering mechanism and the one that can push steering rod, etc.

  The hydraulic pump provided by mechanical power steering is driven by a belt, which means that the steering pump can only run when the engine is running, which is why the steering wheel power disappears after the engine is turned off. On the steering machine, there is a mechanical valve that can rotate with the steering column. When the steering wheel does not rotate left and right, the pressure in the chambers on both sides of the piston is consistent and in a balanced state. When the steering wheel rotates, the mechanical valve connected to the steering column will be opened or closed accordingly, and the oil on one side will return directly to the oil storage tank without passing through the hydraulic cylinder, and the oil on the other side will continue to be injected into the hydraulic cylinder, so that the pressure difference between the two sides of the piston will be pushed under the action of hydraulic force, and then the auxiliary force will be generated to push the steering rod to steer the wheels, which greatly reduces the force required for us to turn the steering wheel.

Home of the car

  Another advantage of hydraulic power steering system is to improve comfort and safety. When the wheels jump violently and the tires turn involuntarily when encountering potholes, the vibration can be well buffered and absorbed by the action of hydraulic pressure on the piston, which greatly reduces the vibration transmitted to the steering wheel. At the same time, this structure also improves the safety. For example, when a vehicle using the traditional rack-and-pinion mechanism turns, the tire suddenly changes direction when it encounters a pothole, and the rack will drive the gear to reverse the steering wheel, resulting in the situation of "beater", which is easy to hurt the driver’s hand, so there will be no such problem in a hydraulically assisted vehicle.

  Mechanical hydraulic booster features:The whole system is a mechanical structure, from the mechanical hydraulic pump driven by the belt to the hydraulic mechanical valve body on the steering column, without any electronic system, with mature and stable technology, high reliability and wide application range. Even if the hydraulic system of the vehicle fails and loses power, it can still rely on the traditional rack and pinion mechanism for steering. Disadvantages are complex structure, large space occupation and high manufacturing cost, which also makes the maintenance difficult and costly. And because the hydraulic pump is driven by the engine belt, it will consume part of the power of the engine, which will affect the fuel economy and the power of the vehicle, especially for small-displacement vehicles with relatively weak power. In addition, the strength of the mechanical hydraulic power-assisted system is not adjustable, so it is difficult to take into account the different requirements for pointing accuracy when driving at low speed and high speed.

● Electro-hydraulic booster

  The so-called Electro-hydraulic power steering (EHPS for short) has exactly the same principle as mechanical hydraulic power steering, but the biggest difference from mechanical hydraulic power steering is that instead of using a hydraulic pump driven by an engine through a belt, it is replaced by an electric pump.

Home of the car

  The advantages of electro-hydraulic power assist are firstly reflected in energy consumption. First, the electronic pump driven by electric energy uses the electric energy output by the generator and the battery, and no longer consumes the power of the engine itself. The start and stop of the electronic pump are all controlled by the electronic system. When it is not steering, the electronic pump is turned off, unlike the mechanical hydraulic power assist pump, which is always linked with the engine, further reducing energy consumption.

  Secondly, the electronic control unit of the electro-hydraulic power steering system can change the power of steering assistance by processing the information of sensors such as speed sensor, lateral acceleration sensor and steering angle sensor, and changing the flow rate of the electronic pump in real time, that is, the function of variable power assistance with speed. Of course, it is not only the electro-hydraulic power assist that can realize the variable power assist with speed. We will introduce various "variable" power assist steering systems in detail in later articles.

  Electro-hydraulic power assist has been gradually popularized since the late 1990s, and brands such as,,,,, and have models using electro-hydraulic power assist system. We are familiar with, and other models use such a system.

Citroen Dongfeng Citroen Triumphal 2006 2.0L Automatic Elite

"Triumph, old models and other models use electro-hydraulic power."

Ford Changan Ford Focus 2011 sedan 2.0AT luxury model

  Why can’t electro-hydraulic assist replace mechanical hydraulic assist?

  No matter from the aspects of technology, function or economy, electro-hydraulic power assistance has more advantages than mechanical hydraulic power assistance. However, at present, electro-hydraulic power assistance has not been able to replace mechanical hydraulic power assistance for the following reasons:

  1. The cost of electro-hydraulic booster is higher. Compared with the mechanical hydraulic power-assisted system, after adding the electronic control system and replacing it with the electronic pump, the manufacturing cost of electronic hydraulic power-assisted system is higher, the technology is more complicated, and the difficulty and cost of maintenance are also increased.

  2. The reliability is not as good as that of mechanical hydraulic booster. In addition to the failure of steering mechanism and hydraulic mechanism, electro-hydraulic power assist also increases the possibility of electrical system failure, so its reliability is not as good as that of traditional hydraulic power assist system.

  3. The assistance is limited. Although the use of electronic pump has obvious advantages, it needs to be driven by the electric energy of the generator, and the vehicle-mounted generator itself and the maximum current it can provide are limited, so the power of the electronic pump is also limited, and the load it can carry is also limited. Therefore, at present, most of the models that use electro-hydraulic power are medium-sized vehicles. For vehicles that need greater assistance, the electro-hydraulic assistance system is beyond the reach.

  4. Evolved mechanical hydraulic booster system. With the development of technology, the variable speed function of electro-hydraulic power-assisted system has been realized on the evolved mechanical hydraulic power-assisted system (using solenoid valve body technology), and even a variable speed ratio system has been derived from the mechanical hydraulic power-assisted steering system, so the mechanical hydraulic power-assisted system with higher reliability and load-bearing capacity is still welcomed by manufacturers.

How to screen breast cancer? The screening standard suitable for Chinese is coming.

Recently, the China Breast Cancer Screening Standard (T/CPMA 014-2020) proposed by China National Cancer Center was published online in chinese journal of cancer prevention and treatment. The correspondent is Professor He Jie, director of National Cancer Center and academician of China Academy of Sciences.

As a common cancer, according to the latest global cancer burden data released by the International Agency for Research on Cancer (IARC) of the World Health Organization in 2020, there were 2.26 million new breast cancer cases in the world in 2020, surpassing lung cancer (2.21 million cases) for the first time, becoming the largest cancer in the world, accounting for 11.7% of new cancer cases. Among the newly diagnosed cancer patients, one in every eight is a breast cancer patient. China is a big country with breast cancer. In 2020, there will be about 420,000 new cases of breast cancer and nearly 120,000 deaths.

Screening, improving the detection rate of early breast cancer and precancerous lesions, and timely and effective treatment are important measures to improve the prognosis of breast cancer and reduce the risk of death. The standards put forward suggestions on the population, measures, results and management of breast cancer screening in China. We have sorted out the relevant contents, hoping to help you better understand the knowledge of breast cancer screening.

Who should have breast cancer screening?

The standard suggests that people at high risk of breast cancer should be screened from the age of 40; The general risk population (all school-age women except the high-risk population) should be screened for breast cancer between 45 and 70 years old.

High-risk population

Women who meet any of the following conditions 1, 2 and 3 are at high risk of breast cancer.

1. Women with genetic family history, that is, women with any of the following: 1) First-degree relatives (mothers, daughters and sisters) have a history of breast cancer or ovarian cancer; 2) Among the second-degree relatives (aunts, grandmothers and grandmothers), two or more people suffered from breast cancer before the age of 50; 3) Among the second-degree relatives, 2 or more have ovarian cancer before the age of 50; 4) At least one first-degree relative carries a known pathogenic genetic mutation of BRCA1/2 gene, or carries a pathogenic genetic mutation of BRCA1/2 gene himself.

2. Have any of the following: 1) Age of menarche ≤12 years old; 2) menopausal age ≥55 years old; 3) Have a history of breast biopsy or surgery for benign breast diseases, or a history of atypical hyperplasia of breast (lobules or ducts) confirmed by pathology; 4) Use hormone replacement therapy of "estrogen and progesterone combination" for not less than half a year; 5) X-ray examination of breast after 45 years old suggests that the type of breast parenchyma (or breast density) is uneven compactness or compactness.

Note: Breast parenchyma types can be divided into fat type, scattered fibrous gland type, heterogeneous dense type (which may cover small masses) and dense type (which reduces the sensitivity of breast cancer detection).

3. Those who have any of the following two items: 1) No breast-feeding history or breast-feeding time less than 4 months; 2) No history of live birth (including never giving birth, abortion or stillbirth) or the age of first live birth ≥30 years old; 3) hormone replacement therapy using only "estrogen" for not less than half a year; 4) Abortion (including natural abortion and induced abortion) shall not be less than 2 times.

How to screen?

General risk population: breast ultrasound examination should be performed every 1-2 years; If you do not have the conditions for breast ultrasound examination, you should use mammography.

High-risk population: breast ultrasound combined with mammography is performed once a year.

How to understand the screening results?

Classification of diagnostic results of mammography

The diagnostic results of mammography are usually classified by the Breast Imaging Reporting and Data System (BI-RADS), which is formulated by American Radiological Society (ACR) and widely used internationally.

1. BI-RADS 0: The existing image failed to complete the evaluation, and other image examinations need to be added.

2. BI-RADS 1: normal, no abnormality was found in mammography. The possibility of malignancy is 0%.

3. BI-RADS 2: Benign findings, with definite benign changes and no malignant signs. The possibility of malignancy is 0%.

4. BI-RADS 3: Benign lesions that may be large. 0% < malignant possibility ≤2%.

5. BI-RADS 4: Suspected malignant lesions, but without typical malignant signs. 2% < malignant possibility < 95%.

6. BI-RADS 4A: low-grade suspected malignancy. 2% < malignant possibility ≤10%.

7. BI-RADS 4B: moderately suspected malignant. 10% < malignant possibility ≤50%.

8. BI-RADS 4C: highly suspected malignant. 50% < malignant possibility < 95%.

9. BI-RADS 5: Highly suggestive of malignant lesions with typical imaging features of breast cancer. Malignant possibility ≥95%.

The classification of ultrasound evaluation refers to the screening of National Comprehensive Cancer Network (NCCN) and the BI-RADS classification standard proposed by American Radiological Society.

1. BI-RADS 0: The diagnostic information obtained by ultrasound is incomplete and cannot be evaluated, and it needs to be evaluated after other imaging examinations.

2. BI-RADS 1: negative, no abnormality was found by ultrasound. The possibility of malignancy is 0%.

3. BI-RADS 2: Benign lesions, with definite benign changes and no malignant signs. The possibility of malignancy is 0%.

4. BI-RADS 3: Benign lesions that may be large. 0% < malignant possibility ≤2%.

5. BI-RADS 4: Suspected malignant lesions, but without typical malignant signs. 2% < malignant possibility < 95%.

6. BI-RADS 4A: low-grade suspected malignancy. 2% < malignant possibility ≤10%.

7. BI-RADS 4B: moderately suspected malignant. 10% < malignant possibility ≤50%.

8. BI-RADS 4C: highly suspected malignant. 50% < malignant possibility < 95%.

9. BI-RADS 5: Highly suggestive of malignant lesions with typical imaging features of breast cancer. Malignant possibility ≥95%.

Screening result management

1. BI-RADS 1 and BI-RADS 2 need no special treatment.

2. BI-RADS 3:

The evaluation of mammography is BI-RADS 3, so it is advisable to reexamine the breast on the lesion side at the next 6 months, and reexamine the breast on both sides at the 12th and 24th months.

If the lesion remains stable, it can continue to be reexamined, and if it has not changed for 2-3 years, it can be reduced to BI-RADS 2. If the lesion disappears or shrinks during the reexamination, it can be directly evaluated as BI-RADS 2 or BI-RADS 1. Biopsy should be considered if suspicious findings are found in the lesions during the reexamination.

The breast ultrasound evaluation is BI-RADS 3, so it is advisable to have breast ultrasound reexamination in 3-6 months, and it can be reduced to BI-RADS 2 if there is no change after 2 years of follow-up.

3. BI-RADS 4A: Further imaging examination and biopsy are needed.

4. BI-RADS 4B: Further imaging examination is needed, and biopsy is appropriate.

5. BI-RADS 4C and BI-RADS 5: Biopsy should be performed.

According to the standard, the breast physiological characteristics and breast cancer epidemic characteristics of women in China are quite different from those in western countries, so we can’t copy foreign experience. Establishing breast cancer screening standards suitable for women in China will play an important role in improving the scientificity, feasibility and practicability of breast cancer screening and reducing the incidence and mortality of breast cancer.

Highlight the word "research" and make better use of teaching materials.

  Authors: Yang Haojie (Ph.D., Institute of Curriculum Textbooks, Ministry of Education) and He Chenggang (Researcher, Institute of Curriculum Textbooks, Ministry of Education)

  Recently, Publicity Department of the Communist Party of China, together with the Ministry of Education, has published an Introduction to Socialism with Chinese characteristics Thought of the Supreme Leader in the New Era (hereinafter referred to as "Introduction"), which is a key measure to further promote the introduction of Socialism with Chinese characteristics Thought of the Supreme Leader in the New Era into teaching materials, into the classroom and into the mind, to better implement the fundamental task of educating people, and to meet the people’s needs for high-quality teaching materials. The publication of Introduction is an important event in the political life of the party and the country, an important event in the teaching work of teachers and a happy event in the study of hundreds of millions of young students. It is necessary to fully understand the great significance of the textbook Introduction in cultivating people with the innovative theory of the party, guiding young students to establish a correct world outlook, outlook on life and values, and striving to become a new person of the times who is responsible for national rejuvenation, highlighting the word "research" and further using the textbook well.

  Adhere to the "three bases" and study the teaching materials in depth.

  Introduction consists of three parts: introduction, 17 chapters and conclusion, which comprehensively reflects the latest achievements of the modernization of Marxism in China, great practice and great changes in the new era, and is a consensus research achievement in academic circles, with authority. The vast number of front-line teachers at all levels and schools in China should study textbooks, not only by reading one step first, but also by studying one level in depth, and even more by understanding one level in detail, so as to get into their minds and hearts.

  First of all, based on the history of the party’s unity and leading the people for more than a hundred years, we should study the teaching materials comprehensively.Grasp the theme, main line and main content of the textbook "Introduction" as a whole, grasp the theoretical panorama of the latest achievements in the modernization of Marxism in China, and make sure that you really learn, believe and use it.

  Secondly, based on the great practice and great changes in the new era in the past ten years, we should study the teaching materials in depth.Summarize and clarify the basic context of the textbook "Introduction", strengthen the thinking of historical logic in great practice, realistic logic in great change and theoretical logic in great achievements, so that history, reality and theory can "complement each other" in the textbook.

  Thirdly, based on the overall situation of the great rejuvenation strategy of the Chinese nation and the unprecedented changes in the world for a hundred years, systematically study the teaching materials.Under the guidance of the Supreme Leader’s Socialism with Chinese characteristics Thought in the new era, we will study and analyze the complex international situation and great risks and challenges we are facing with a developmental vision and a comparative attitude, deepen our understanding of the great struggle, great project, great cause and great dream of the Party leading the people in the new era, constantly enhance our road, theory, system and cultural identity, and strengthen our "four self-confidences".

  Adhere to the "three unifications" and study textbooks on special topics.

  The textbook "Introduction" adheres to the educational law, highlights the teaching orientation, pays attention to being close to the cognitive characteristics of young students, and adapts to the acceptance habits of young people. It is an essential book and core textbook for cultivating young students to become builders and successors of Socialism with Chinese characteristics, and has applicability. As the first unified textbook that comprehensively and systematically expounds the Supreme Leader’s Socialism with Chinese characteristics Thought in the new era, colleges and universities across the country should adhere to the "three unifications" to organize special research textbooks, and generally explain the background and actual needs of the unified compilation of textbooks, the framework and theoretical innovation of textbook compilation, so as to provide scientific methodological guidance for teaching courses and using textbooks well.

  First, we must adhere to the unity of politics and academic rationality.Deal with the dialectical relationship between firm ideals and beliefs and firm truth and beliefs. Believing in truth is the basis and premise of firm ideals and beliefs. Studying textbooks is to profoundly understand the truth power and practical power of Socialism with Chinese characteristics Thought of the Supreme Leader in the new era, strengthen Marxist beliefs, the lofty ideals of communism and the common ideals of Socialism with Chinese characteristics, and further strengthen ideals and beliefs.

  Second, we must adhere to the unity of value and knowledge.Deal with the dialectical relationship between the principle of reading the original text and learning the course materials. Studying the course materials should be combined with learning the basic principles of Marxism, the principle of reading the original text and learning the "five histories". We should not only learn the main contents of the teaching materials, but also grasp the ideological science system and understand the theoretical philosophy of truth contained in the Supreme Leader’s Socialism with Chinese characteristics Thought in the new era.

  Third, we must adhere to the unity of theory and practice.Dealing with the dialectical relationship between theoretical guidance and practical development, the purpose of learning is to apply it, and to talk about the theoretical value of Socialism with Chinese characteristics Thought, the supreme leader in the new era, guiding practical development to achieve historic changes and achievements in detail, so as to enhance the sense of practical acquisition, ability improvement and motivation of young people in the new era.

  Adhere to the "three focuses" and organize research teaching materials

  Introduction is an important achievement in promoting the construction of the teaching material system of philosophy and social sciences with China characteristics, which reflects the requirements for the integrated education of ideological and political courses in universities, primary and secondary schools, and provides a model for strengthening the construction and management of teaching materials in the new era. The professional research platform of national curriculum textbooks, the key research bases of textbook construction and the textbook research institutions in colleges and universities should gather capable forces to study the textbook Introduction, focus on the major theoretical and practical problems of textbook construction, sort out and summarize mature experiences, summarize and refine basic laws, and promote the construction of a high-quality textbook system to serve and support the high-quality development of education.

  First, focus on the innovation of teaching material construction mechanism,Carefully sort out all the links in the whole process of management research for editing and reviewing the textbook Introduction, and study the innovative practices and effective experiences in the mechanism of the textbook Introduction from the aspects of writing needs, implementation plan, team formation, discussion and review, publication and use tracking, so as to create an era model for the construction and management of the textbook.

  Second, focus on the realization of teaching materials to educate people.Accurately grasp the functional orientation of the textbook "Introduction" to cultivate new people in the era, and study the core leading role of the textbook "Introduction" in curriculum integration, teaching integration, evaluation integration and goal integration according to the requirements of ideological and political courses integration in universities, primary and secondary schools, so as to lay the foundation for the realization of all-round education, whole-process education and all-round education.

  Third, focus on the construction of teaching material discourse system,Fully understand the theoretical value of "Introduction" as an important achievement in the construction of teaching material system of philosophy and social sciences with China characteristics, accelerate the strategic goal of building a discourse system of philosophy and social sciences with China characteristics by benchmarking, study the active exploration of teaching materials in the construction of Marxist discourse system with China characteristics and times, and gradually highlight the China characteristics, China style and China style in the construction of teaching material discourse system.

Fine design of epidemic prevention health code

COVID-19 is still spreading around the world, and prevention and control will become the norm. How to prevent and control it efficiently and finely, and minimize the impact on people, maybe we can make a fuss about health codes.

Now the function and significance of various health codes is actually mainly to provide data by big data statistics. But not fine enough. There are mainly the following problems:

  • How to ensure the authenticity of information
  • People in high-risk areas are not necessarily high-risk, so high-risk areas should not be divided, but high-risk people should be defined.
  • Only people who are in close contact with the confirmed patients are high-risk people. It is most important to inform these people in time and check them out.
  • The core of prevention and treatment of infectious diseases is early detection and early isolation. How to find it and isolate it as soon as possible is the most important thing.

Universal testing, screening out all patients, and then centralized treatment, this is the most ideal method. However, based on the actual situation, it is more difficult to realize this. Then set up more detection links, such as the temperature detection of residential buildings, which is this role. When the abnormality is detected, further nucleic acid detection will be conducted. If the diagnosis is confirmed, all close contacts will be screened again to find the car infected person. This should be done quickly and accurately. You can realize all accounts receivable, and you should check everything.

National epidemic prevention requires a national epidemic prevention system. Everyone and each unit play different roles in the whole system. These categories are probably needed in this system:

  • Brain center cloud computing platform:Such a large amount of data and responsible data storage certainly need a powerful data storage and technical platform, and China, which has experienced the test of Spring Festival travel rush and the Double Eleven, is not lacking in this ability.
  • All-round primary inspection:This requires our Zu Guoqiang’s strong organizational ability to do a good job of detection at every small, building subway and other personnel flow nodes. The main function is to find people with fever and abnormal health codes, and send them for inspection in time if abnormal conditions are found. Do early detection and early isolation.
  • Nucleic acid detection:Rapid and convenient detection can expand the detection range. In South Korea, PCR nucleic acid detection method was adopted on January 31st, and the diagnosis result can be obtained in 6 hours. The "drive-through" detection station can detect about 380 people every day. This practice can quickly deal with a large number of testers and effectively reduce the contact between medical staff and high-risk groups. It used to take 30 minutes for each person to test, but now it only takes 10 minutes to complete. This may be used for reference.

Face recognition real name login:Nowadays, whether it is the card opening of financial banks or the real-name authentication of the three major operators, remote face recognition verification has been realized, and the uniqueness of the national ID cards provides a data basis for face recognition. Relying on the camera of smart phone, face recognition login is completed. Thereby ensuring the correctness of the information. Face recognition login+mobile phone verification code. Don’t enter complicated information such as the place of entry, the place of household registration, and the place of residence.

Close contacts real-time storage:Fine epidemic prevention is to accurately find infected people and close contacts with confirmed patients. Now the way to find close contacts is too rude. One person is diagnosed, the whole building belongs to close contacts, and someone in a train is diagnosed and needs close contacts to check the relevant trains themselves. This greatly misses these potential threat groups. Or accidentally injure someone who is not really close to you. Using the Bluetooth technology of mobile phone, you can search for additional Bluetooth devices in real time and upload them for filing. Bluetooth can search for devices within 10-20 meters, and record the contact time of storage devices and the MAC address of devices. Within 10-20 meters, those who have been in contact for more than 60 seconds are close contacts in the true sense.

Real-time location information:The record of real-time location information of mobile phone can tell you where you have been in contact with close contacts when pushing information, and provide information judgment for self-infection rate through self-judgment of personal protective measures at that time.
Real-time push of abnormal information: when someone in close contact with an individual is diagnosed on the 14th, the mobile phone will automatically push the message. The message template involves the following information: time, place, number of contacts, contact duration, and the nearest nucleic acid detection point.

For example:

Hello; At 3:50 p.m. on April 6, 2020, a confirmed patient met with you for about 10 meters for 300 seconds near Chaoyangmen subway in Chaoyang District, Beijing.

Now the nearest nucleic acid detection point is the outpatient department of Chaoyang Hospital. It is recommended that you do a good job of protection and see a doctor immediately.

There are only two states of health code, no abnormality and abnormal. Face recognition login shows the status, which will be invalid after 1 minute. You need to log in again. All residential buildings only need to check the health code, and if there is any abnormal state, they will not pass, and urge them to do nucleic acid testing. If the testing is negative, the hospital data will be restored to no abnormal state after synchronization.

Exception definition:Within 14 days, if there is a confirmed case in the Bluetooth information record, it will be displayed as abnormal.

Eliminate anomalies:Go to the hospital for nucleic acid detection. If it is negative, the hospital data will be uploaded and the abnormal state will be automatically lifted. If it is positive, the system will automatically inform the user to contact the confirmed user, and then inform the contacted user to do nucleic acid testing.

At present, the health code is too rough, and the overall structure is centralized. From top to bottom, it lacks a dimension, that is, information communication between groups. Adding this dimension can realize timely tracking and timely push, and the whole process is more automated, reducing a lot of manual intervention.

To prepare for a protracted war, make full use of existing technical means, give full play to data intelligence, and fine epidemic prevention means to minimize the impact on personnel activities on the premise of accurate positioning. I didn’t mention the issue of data security in the whole article because we can’t give up eating because of choking at this stage. The whole design is still described by big lines. If you have any shortcomings, please brainstorm and comment.

Cross-border e-commerce: bringing China closer to the world.

The "Several Policies and Measures on Promoting the Stable Growth of Foreign Trade" issued by the Ministry of Commerce recently proposed to promote the development of cross-border e-commerce. The status and importance of cross-border e-commerce does not stop there. At present, it has been included as a new clause in some newly signed and escalating bilateral free trade agreements.

In recent years, new foreign trade formats and new modes have emerged in China, especially cross-border e-commerce, which has become a "new engine" to stimulate foreign trade growth with its rapid development. Relying on strong supply capacity, faster customs clearance efficiency and more cost-effective customized services, cross-border e-commerce is promoting more China products to link to the global market. Cross-border packages smoothly shuttle between more countries and regions, bringing China closer to the world.

"New clause" of FTA

Data show that in the first three quarters of this year, the import and export of cross-border e-commerce in China increased by 11.5% year-on-year, accounting for nearly 6% of China’s foreign trade. As a new format and model in the field of foreign trade, the rapid development of cross-border e-commerce is a pragmatic achievement of China’s continuous expansion of high-level opening-up and promotion of bilateral and multilateral economic and trade cooperation.

On November 14th, China and Peru signed a protocol to upgrade the FTA, adding five chapters to the original FTA, including e-commerce. On August 22nd, the joint communique between China and the Belarusian government pointed out that the two sides will strengthen cooperation in the field of e-commerce and encourage Belarusian enterprises to enter the major e-commerce platforms in China … Recently, the newly signed bilateral free trade agreement or the upgraded free trade agreement has included cross-border e-commerce as a new clause, which has injected momentum into the development of cross-border e-commerce between China and its free trade partners.

"The inclusion of cross-border e-commerce as a new clause in the bilateral free trade agreement has released a new signal that China attaches great importance to the role of cross-border e-commerce in international trade and regards it as an important tool to promote trade liberalization and facilitation." Hong Yong, a think tank expert of China Digital and Real Integration 50 Forum, told the International Business Daily reporter.

"This is a very positive signal." Wang Chunming, executive director and general manager of Harbin Fuhuo International Supply Chain Co., Ltd., told the International Business Daily that the inclusion of cross-border e-commerce in the terms of the bilateral free trade agreement not only simplifies the trade process of enterprises, reduces the barriers to cross-border transactions of enterprises, but also deepens the cooperation between enterprises and other countries in e-commerce. "On the other hand, this move also shows that while promoting the high-quality development of foreign trade, China has taken the digital economy and cross-border e-commerce as a key link in its future development, which is bound to promote more enterprises to participate in the international market."

In Hong Yong’s view, this move also reflects China’s determination to play a more active role in global digital economic governance and trade rule-making. "China has always been committed to jointly formulating rules through international cooperation to promote the healthy and orderly development of cross-border e-commerce."

Cross-border e-commerce "acceleration"

"Our e-commerce sales have nearly tripled year-on-year, and the logistics speed has been shortened from more than 40 days to about 25 days now." Wang Chunming said that the company’s latest batch of orders were delivered from Belarus to Erenhot, and the goods were distributed to all parts of the country after unloading. "Five cars were delivered this morning, and four cars will be’ taken’ later."

There are many foreign trade enterprises like Wang Chunming that enjoy the dividend of cross-border e-commerce development. In Guangzhou and Baiyun Airport Comprehensive Bonded Zone, batches of small packages imported directly by cross-border e-commerce such as beauty and skin care products and clothing accessories were sorted and sent to all parts of the country. In Sichuan, in eight provincial-level cross-border e-commerce industrial parks, 400 cross-border e-commerce source factories operate efficiently, and batches of products with Bashu characteristics go overseas from here.

Since 2014, cross-border e-commerce has been written into the government work report for 11 consecutive years. From 1.06 trillion yuan in 2018 to 2.38 trillion yuan in 2023, the import and export of cross-border e-commerce in China increased by 1.2 times in five years.

Hong Yong believes that the rapid development of cross-border e-commerce in China is mainly due to its ability to effectively reduce transaction costs, shorten transaction chains, improve transaction efficiency, and meet the personalized and diversified needs of consumers.

According to customs statistics, in the first eight months of this year, there were 630,000 foreign trade business entities with import and export performance in China, up 8.8% year-on-year. According to preliminary statistics, the number of cross-border e-commerce entities in China has exceeded 120,000, and the number of cross-border e-commerce industrial parks has exceeded 1,000. Relying on 165 cross-border e-commerce comprehensive test zones in China, cross-border e-commerce has driven more enterprises from various industrial belts to participate in international trade.

Wang Chunming said that these data reflect the great changes in global consumption and trade patterns. "In the past, international trade mainly relied on traditional channels and logistics models. Nowadays, consumers can purchase global goods more conveniently through e-commerce platforms, and enterprises can also use e-commerce platforms to break geographical restrictions and enter the international market."

However, the industry has also noticed that the development of cross-border e-commerce still faces some challenges, such as the inconvenience of cross-border exchange, the need to improve cross-border e-commerce service capabilities, and differences in laws and regulations. In the next step, how to promote the "new engine" with high quality is the key to the industry’s stability and far-reaching.

In this regard, Wang Chunming suggested: First, strengthen policy coordination with other countries, increase the promotion of overseas markets, and promote more cross-border e-commerce enterprises to enter the international market. The second is to promote the combination of cross-border e-commerce platforms and localized services to help domestic enterprises better adapt to the international market, especially to provide more support in product compliance and payment security. "Only when policy, technology and market work together can we provide a better ecological environment for cross-border e-commerce and further promote its healthy and sustainable development."

Hong Yong suggested that the first is to strengthen infrastructure construction, such as improving domestic and international logistics networks and improving the security and convenience of cross-border payment systems. The second is to optimize the policy environment and reduce the operating costs of cross-border e-commerce enterprises through measures such as decentralization and reduction of examination and approval links. The third is to strengthen personnel training and technical support, establish a training mechanism for cross-border e-commerce professionals, and promote the application of technological innovation. Fourth, strengthen international cooperation, actively participate in the formulation of international rules, and create a fairer and more transparent external environment for cross-border e-commerce enterprises.

Buying a house and a car when you are in love, what should I do after breaking up?

Illustration Wang Chen Jun

  Transfer money during love, do you need to return it after breaking up? Buying a wedding room and registering your girlfriend’s name is a gift or a joint house purchase? Buying a car before marriage is a bride price or a gift. Can I ask for a return after breaking up? Recently, Haidian court tried many such cases, and the judge explained them in detail and gave a prompt.

  Case:

  Forced by his girlfriend to write an iou? If "coercion" is not proved, it will be returned.

  Xiao Na said that during her love with Xiaolei, Xiaolei borrowed 600,000 yuan from her on the grounds of revolving business, and then repaid 30,000 yuan. In July 2015, Xiaolei issued a debit note to her, promising to repay it at maturity, but failed to fulfill the repayment promise after the expiration. She repeatedly urged for no results, so she sued Xiaolei for repaying the loan principal of 570,000 yuan and paying interest.

  During the trial, Xiao Na submitted the IOUs and transfer records to the court. The content of the loan shows: "Xiaolei borrowed 600,000 yuan from Xiaona today, and has already paid back 30,000 yuan, leaving 570,000 yuan to be paid off before October 2015. On July 30, 2015, the borrower Xiao Lei. " According to the personal account statement of Xiao Na Bank, Xiao Na transferred RMB 600,000 to Xiaolei from 2014 to 2015 by mobile phone.

  Xiaolei recognized the transfer record, but said that he and Xiao Na were originally in love, and they often transferred money to each other during their love. He did not borrow money from Xiaona. The two parties originally planned to hold a wedding in August 2015, but a few days before the wedding, Xiao Na and several people forced him to write this IOU.

  The court held that according to the evidence submitted by Xiao Na, it can be concluded that there is a private loan relationship between her and Xiaolei, and Xiaolei should fulfill the repayment obligation, but the failure to repay all the loans so far has constituted a breach of contract. Xiaolei claimed that the IOU was issued under the coercion of Xiao Na, but no evidence was provided, so the court refused to accept it. Finally, the court ordered Xiaolei to repay Xiao Na’s loan of 570,000 yuan and pay corresponding interest.

  The judge suggested that the lender should keep the payment voucher.

  Hu Meiqing of Haidian Court said that it is very common for lovers to transfer money to each other. After the relationship ends, it is not uncommon for one party to advocate "transferring money to borrow money" and sue. Because many lovers write IOUs to each other for emotional reasons, but no loans actually occur, it is more complicated to identify such loan relationships.

  Is it a loan relationship to transfer money during the relationship? The judge believes that the party who advocates the establishment of the loan relationship generally bears the burden of proof on whether the loan relationship is true and the actual delivery of the loan. Therefore, it is particularly important for lenders to keep relevant payment vouchers. Borrowing between lovers, it is best to leave traces by means of transfer, etc., and at the same time pay attention to keeping the bank’s running water and transaction records. If you need to pay a large amount of cash, you should keep the bank’s withdrawal records, and if necessary, you should ask the other party to issue an iou or sign a loan agreement.

  Case:

  Before marriage, the court awarded 50% of the property rights under the name of one registered person.

  Another pair of lovers, Zhou Yang and Li Ting, have been dating since they were in college, and they broke up in 2015. In October 2012, the two parties jointly invested to buy a house in Haidian District, Beijing. Because Zhou Yang was not qualified to buy a house at that time, they negotiated and signed a sales contract with the real estate company in the name of Li Ting. After that, Zhou Yang paid the down payment of 1,588,519 yuan, the purchase price of 160,000 yuan, and Li Ting paid the remaining house price of 440,000 yuan. The house was registered in the name of Li Ting. On June 30, 2016, after obtaining the qualification to buy a house, Zhou Yang contacted Li Ting to handle the house transfer, but Li Ting ignored it. Zhou Yang found out that she planned to sell the house through an intermediary company.

  In this regard, Zhou Yang believes that the joint purchase of a house by both parties and Li Ting’s unauthorized sale have seriously infringed on their legitimate rights and interests, so he sued his ex-girlfriend and demanded that the house be divided according to law, with himself and Li Ting accounting for 78.3% and 21.7% respectively.

  However, Li Ting said that the house was registered in her personal name and belonged to personal property, and Zhou Yang had no right to divide it; Moreover, the purchase price paid by Zhou Yang is a gift to her, and there is no common property between the two parties.

  During the trial, both of them said that they intended to buy a house as a wedding room, but later they broke up due to emotional reasons, and the house has been occupied by Li Ting. The court held that it was an act of jointly purchasing property with marriage intention to jointly invest and buy a house in the name of Li during their love. Now the two sides have failed to get married and end their love relationship, and the purpose of buying a house has been impossible to achieve. Although the property right is registered in the name of the woman, it should still be recognized as common property. In the end, the court ruled that the house was jointly owned by two people, with each party holding 50% of the property rights, and Li Ting assisted Zhou Yang in the registration of the property rights.

  The judge suggested that buying a house together during love is regarded as common property.

  It is more and more common to buy a house jointly before marriage. Hu Meiqing believes that houses, cars and furniture jointly invested by both parties during the period of love should be regarded as common property. At the termination of the joint ownership relationship, the division of the joint property shall be handled according to the agreement if there is an agreement, and if there is no agreement, the factors such as the contribution of the co-owners, the contribution to the joint property and the actual needs of the co-owners in production and life shall be considered. In order to avoid disputes in the future, we should be cautious in buying a house together during the period of love. We can sign a capital contribution agreement in advance to stipulate their respective shares, and at the same time, we should keep relevant evidence such as bank transfer records and payment vouchers.

  Case:

  Buying a car, registering in the name of the prospective mother-in-law, breaking up, and the court awarded the refund of the car.

  A couple decided to get married. Li Wen said that he spent 226,856.9 yuan to buy an SUV as a wedding gift at the request of his girlfriend Zhang Xia. Because they were not qualified to buy a car in Beijing, they registered the car in the name of Zhang Xia’s mother Wang. However, the two sides broke up soon due to personality and other reasons. Li Wen’s request for Zhang Xia to return the car purchase fee was rejected, so he sued Zhang Xia’s mother and daughter for returning the engagement price of more than 230,000 yuan.

  During the trial, Zhang Xia’s mother and daughter argued that there was no engagement between Li Wen and Zhang Xia, and the vehicle involved in the case that Li Wen invested and registered under Wang’s name was not an engagement bride price. Because of their long relationship, Li Wen mentioned breaking up many times. Before buying a car, Li Wen broke up with Zhang Xia again. This time, he proposed to buy a car for Zhang Xia to make up for his feelings. Moreover, when buying a car, the old car under Wang’s name is discounted to 8000 yuan, so the newly bought car also has Wang’s rights and interests, which should be divided before disposal. The used car has been depreciated and should not be returned at the new car price.

  The court held that the car purchase money should belong to Li Wen’s expenditure for the purpose of marriage and has the nature of bride price. Although Zhang Xia’s mother and daughter claimed that Li Wen’s contribution was a gift, they did not provide sufficient evidence and the court did not support it. In view of their failure to get married, Li Wen has the right to demand that the other party return the corresponding expenses incurred for marriage. Regarding the amount of money to be refunded, it should be judged according to Li Wen’s actual expenses for purchasing the car. Finally, the court ruled that Zhang Xia’s mother and daughter returned Li Wen’s car purchase price of 232,983.79 yuan.

  Judge’s tip: unmarried people ask for the support of the bride price court.

  Hu Meiqing said that the phenomenon of paying bride price before marriage is a custom, which is popular in many parts of China.

  The recently updated "School Profile" of the school website (the data deadline is June 10th, 2023) states, "Hebei University of Traditional Chinese Medicine was founded in 1956, originally named as Hebei College of Traditional Chinese Medicine, with its location in Baoding City, Hebei Province. In 1957, it began to recruit undergraduates majoring in traditional Chinese medicine, and in 1958 it was named Hebei College of Traditional Chinese Medicine. In 1962, it merged with Tianjin College of Traditional Chinese Medicine, which was affiliated to Hebei Province. In 1969, Tianjin College of Traditional Chinese Medicine was moved to Shijiazhuang and merged with Hebei Medical College to form Hebei New Medical University. In 1983, the independent setting was resumed and enrollment began. In 1995, it merged with Hebei Medical College and Shijiazhuang Medical College to form Hebei Medical University. In 2013, the establishment of Hebei College of Traditional Chinese Medicine was resumed. On June 6, 2023, it was renamed Hebei University of Traditional Chinese Medicine with the approval of the Ministry of Education. "

  Previously, in May this year, the Development Planning Department of the Ministry of Education passed the "Announcement on Approving the Establishment of Undergraduate Colleges and Universities" issued by official website, the Ministry of Education, saying that according to the People’s Republic of China (PRC) Higher Education Law, the Provisional Regulations on the Establishment of Ordinary Colleges and Universities, the Provisional Regulations on the Establishment of Ordinary Undergraduate Schools, and the Standards for the Establishment of Vocational Schools at the Undergraduate Level (Trial), it is proposed to agree to establish seven schools, including Chongqing College of Chinese Medicine, after being inspected and evaluated by experts of the Eighth National College Establishment Evaluation Committee and deliberated by the party group meeting of the Ministry of Education. The publicity time is from May 22 to May 26, 2023.

  Among the seven schools announced this time, the Ministry of Education intends to agree that Hebei College of Traditional Chinese Medicine should be renamed Hebei University of Traditional Chinese Medicine, and the declared province is Hebei Province, and the nature of running a school is public.

  In recent years, Hebei College of Traditional Chinese Medicine and Hebei Province have been actively promoting the renaming of schools.

  In December 2021, the Education Department of Hebei Province mentioned in response to a netizen’s inquiry, "At present, under the strong leadership of the provincial party committee and the provincial government, our province is relying on Hebei College of Traditional Chinese Medicine to build Hebei University of Traditional Chinese Medicine, providing all-round support and guidance in construction funds, talent introduction, education and teaching, and has achieved remarkable results. In the next step, we will continue to take effective measures to increase the promotion and strive to build Hebei University of Traditional Chinese Medicine as soon as possible. "

  Subsequently, in August 2022, the Hebei Provincial Department of Education replied to the netizen’s inquiry that "Hebei College of Traditional Chinese Medicine was renamed Hebei University of Traditional Chinese Medicine", saying, "After performing the provincial evaluation procedure, our province has submitted the application materials for renaming to the Ministry of Education. At present, related work is progressing in an orderly manner in accordance with the procedures for setting up institutions of higher learning. "

Abnormal cycle of Chinese herbal medicine? Maori downward pharmaceutical companies face the choice of price increase.

  "Up for three years, down for three years, flat for three years,The cycle of material price change is generally ten years. Based on this cyclical feature, people in the timber industry expected at the end of 2023 that "the price of timber has been rising for three years and should fall back." However, in the first half of this year, the price of Chinese herbal medicines continued to rise after a short-term adjustment at a high level.

  After a whole year’s inventory digestion of raw materials of traditional Chinese medicine, the gross profit margin of some listed Chinese medicine enterprises changed greatly in the first quarter of this year, and the pressure of raw material cost began to appear.

  Manager Li, a staff member of the original purchasing department of a listed pharmaceutical company, told the Cailian reporter: "Last year, some enterprises did predict the price increase of Chinese medicine raw materials and reserved raw materials, but generally speaking, the raw materials reserved by a company are usually one year, at most two years."

  Since the beginning of this year, the index of Kangmei Chinese herbal medicine has risen from 1810.99 points to 2248.52 points, with an increase of 24.16%. The prices of some varieties such as Atractylodes macrocephala, Cortex Moutan and Radix Paeoniae Alba have increased several times. The prices of Chinese herbal medicines continued to rise overall on the basis of last year’s high prices, while pharmaceutical companies turned to buy high-priced medicinal materials in the market after their own low-priced raw material stocks were exhausted, which may continue to push up the production costs of enterprises. The impact of this year’s price increase on listed Chinese pharmaceutical companies may be deepened.

  The gross profit margin of some Chinese medicine pharmaceutical companies has dropped significantly.

  As can be seen from the financial report data of Chinese medicine listed companies in the first quarter of this year, the gross profit margin of some companies showed a clear downward trend.

  The gross profit margin of the above-mentioned companies in Q1 2024 decreased by an average of 7.65pct compared with the same period of last year, and the gross profit margin of many listed companies decreased by more than 10pct.

  In this regard, Cailian reporters called some listed companies as investors, and some listed companies said that the rising price of Chinese herbal medicines caused cost pressure on the company’s products.(300519.SZ) A company official said: "The price of Chinese herbal medicines doubled from last year to this year."

The price index of Chinese herbal medicines reached a new high this year.

  (002603.SZ) said at the performance briefing that Chinese herbal medicines haveAttribute, there is a certain periodicity. Among the Chinese herbal medicines used in the company’s exclusive products, the prices of some Chinese herbal medicines rose significantly compared with last year, which affected the gross profit margin of some products to some extent. The company will take measures to reduce costs and increase efficiency to maintain relatively stable gross profit margin. In addition, the company will further strengthen the construction of Chinese herbal medicine breeding bases, which can not only guarantee the quality of Chinese herbal medicines from the source, but also alleviate the price pressure of some Chinese herbal medicines to some extent.

  The reporter of Cailian found that the prices of raw materials for the main products of several listed companies with obvious decline in gross profit margin have indeed risen sharply. such as(002728.SZ), the price of raw materials for washing Aster rose from 45 yuan/kg at the end of 2022 to 90 yuan/kg at present, while that of Radix Platycodi rose from 37 yuan/kg to 43 yuan/kg, that of Radix Peucedani rose from 45 yuan/kg to 85 yuan/kg, and that of Radix Glycyrrhizae rose from 22 yuan/kg to 31 yuan/kg. Only Fructus Aurantii decreased slightly from 23 yuan/kg.

  However, it should also be noted that not all companies’ gross profit margin decreases are caused by changes in the cost of medicinal materials, and changes in the company’s product structure and the results of medical insurance negotiations will have a greater impact on the company’s gross profit margin.

  However, for most Chinese medicine pharmaceutical companies, the overall price of Chinese medicine is still on the rise this year, and the gross profit margin of enterprises is affected by the change of raw material cost or more obvious than last year. This year, the prices of some commonly used Chinese herbal medicines, such as Atractylodes macrocephala, Radix Paeoniae Alba and Radix Aucklandiae, have risen sharply, and the market sentiment continues to rise. However, the prices of Chinese herbal medicines, such as Angelica sinensis, Codonopsis pilosula and Glycyrrhiza uralensis, which fell back in the second half of last year due to excessive increase, also showed signs of stabilization.

  After investigating and interviewing the distribution market of Chinese herbal medicines and some listed companies, the reporter of Cailian found that for enterprises with Chinese herbal medicine planting bases, the stability of product supply can be basically guaranteed when the price of Chinese herbal medicines rises, but because most of the medicinal materials in most enterprises are mainly planted in a cooperative way, the purchase price of raw materials is purchased at a protective price that goes with the market, which will not greatly benefit when the price of the medicinal materials rises.

  Manager Li told Cailian reporter: "The raw material reserves of most large Chinese medicine pharmaceutical companies generally analyze the price when purchasing medicinal materials. If the current price of a medicinal material is significantly higher than normal, enterprises generally will not make a large number of purchases, but will only use it as needed."

  If the current pharmaceutical companies start to use the purchasing strategy of low-inventory raw materials, under normal circumstances, the price of high-priced raw materials will slowly decrease due to weak demand, but if the price of this raw material continues to rise, pharmaceutical companies can only passively purchase.

  Enterprises raise prices? Break the contract? Or involution?

  Faced with the rising prices of Chinese herbal medicines, various companies have made different countermeasures for different products and markets.

  Some listed companies have chosen to raise prices, the earliest is(600436.SH) issued the Announcement on Price Adjustment of Leading Products in May 2023, and the company indicated that the retail price of Pien Tze Huang tablets, the leading product, in the domestic market will be raised from 590 yuan to 760 yuan from May 6, 2023, with an increase rate of 28.8%.

  For this price increase, the company said that it was mainly due to the rising cost of raw materials. The reporter of Cailian learned from the staff of Bozhou Drug Merchants Network that the price of bezoar, the main raw material needed by Pien Tze Huang, has increased significantly in the past two years. The price of natural bezoar per kilogram has risen from 500,000 yuan to a maximum of 1.8 million yuan, and now it has dropped slightly to around 1.5 million yuan.

  However, Pien Tze Huang did not raise the price of Angong Niuhuang Pill, another product with bezoar as the main raw material. Earlier, a staff member of another Angong Niuhuang Pill manufacturer told the Cailian reporter that although the price of bezoar has increased greatly, the company’s price increase needs to take into account the situation of competitors of the same product. If the price increase is rushed, it may affect the product sales.

  Except Pien Tze Huang,(002644.SZ) also announced in March this year that it will adjust the ex-factory price of its main proprietary Chinese medicine products due to rising raw materials and production costs, with an average price increase of 9%. Judging from the company’s first quarterly report, the gross profit margin of sales was 31.1%, which was indeed higher than that of 26.66% in the same period of last year. However, since the company raised the price in March, the boosting effect of the price increase on the gross profit margin has not yet fully appeared in the first quarterly report.

  From the product structure of the company, its main products include compound Huangqi Jianpi oral liquid, concentrated Danggui pill, Xiaoyao pill, Angong Niuhuang pill and Liuwei Dihuang pill, most of which are OTC products.The public selling price of e-commerce platforms such as Taobao shows that the price of the company’s products is relatively low compared with similar products of other brands, and the gross profit margin is relatively low.

  In addition, Cailian reporters learned from pharmacies and some listed companies that the prices of main products of listed companies have also been adjusted. among(600993.SH) A company official said that the price of hemorrhoid cream under the company increased slightly. There are also staff members of a medical institution in Shijiazhuang City who reported to the Cailian reporter.The price of quick-acting jiuxin pills has increased recently.

  Under the pressure of rising prices of Chinese herbal medicines, some enterprises chose to breach the contract. Last month, Shandong Province announced two batches of "Announcement on Medical Price and Credit Evaluation Results of Illegal Enterprises in Joint Procurement of Chinese Herbal Pieces by Sanming Purchasing Alliance Inter-provincial Purchasing Alliance". Many enterprises refused to fulfill their commitments and refused to fulfill their purchase, sale or distribution contracts without justifiable reasons.(600085.SH)、The subsidiaries of (600518.SH) and Zhendong Pharmaceutical (300158.SZ) are all on the list of general dishonesty/serious dishonesty.

  The list mainly involves varieties such as Paeonia lactiflora, earthworm, Atractylodes macrocephala, Cortex Moutan, Angelica sinensis, Codonopsis pilosula, etc., which have increased greatly in the second half of last year or this year. Taking Atractylodes macrocephala as an example, the unified price of goods in Bozhou and anguo city markets rose from the lowest 28 yuan per kilogram last year to the highest 170 yuan per kilogram this year.

  Some insiders told Cailian reporter that because the centralized collection of Chinese herbal medicines in Shandong was not forced by the government, but made by micro-doctors, the risk of default was low. Therefore, some pharmaceutical companies chose to take the initiative to default because the cost of some drinks increased too much, if they continued to supply, they would cause serious losses.

  In addition to price increase and default, enterprises have a slightly helpless third choice. Some people in listed companies said that the price increase may face an unfavorable situation of competition with the same products, and now they can only support it, but the company will try its best to reduce various expenses.

  Faced with the rising prices of medicinal materials, some experts in the medicinal materials industry, such as Bozhou and Anguo, have also begun to revise their judgments on the rising cycle of Chinese medicinal materials-"There is a constant inflow of funds, and it may rise." However, some old drug dealers believe that the actual demand growth of medicinal materials is not so great. The price increase of many medicinal materials is not driven by demand, but by funds. Medicinal materials are hoarded in cold storage to form inventory, and the risk of price decline in the market is increasing.
