After the epidemic, how to change the disease control reform?

After every major epidemic, there will always be a lot of reflection, which is the reason for the continuous progress of mankind, also known as learning from a pit. After SARS in 2003, China’s disease prevention and control system was given an opportunity to upgrade: a nationwide unified network direct reporting system for infectious diseases was established, and a case of "unexplained" pneumonia was specially designed in order to avoid the failure of reporting some diseases that have not been clearly defined for the time being; Established the Emergency Regulations for Public Health Emergencies, which stipulated a four-level emergency response mechanism; In many places, the health and epidemic prevention stations were renamed as centers for disease prevention and control, which clarified the establishment standards and improved the administrative level of the units … However, at the end of last year, the sudden COVID-19 epidemic gave us a real test of the achievements of the disease control system construction in the past 17 years, and the results were not satisfactory, exposing many problems.   

What are the main problems?   

(1) The direct reporting system of epidemic situation, which has been built with huge investment, is not running smoothly. 

(B) In the cry of strengthening the construction of disease control system, the number of disease control professionals has decreased compared with 2003. According to the Statistical Bulletin on the Development of Health Care in China in 2019, there are 188,000 people in the Center for Disease Control and Prevention, including 140,000 health technicians, which are 20,000 and 19,000 fewer than in 2003 respectively. 

(C) CDC system, people floating, brain drain accelerated. In June, 2019, at a seminar held in the State Council Development Research Center, Ceng Guang, chief epidemiologist of China Center for Disease Control and Prevention, said: Due to various problems accumulated for a long time and the further decline in income due to recent policy reasons, people in the disease control system are floating and the brain drain is accelerating. In the past three years, there have been as many as 100 young and middle-aged backbones lost from the National Center for Disease Control and Prevention alone, and the brain drain from disease control institutions in some places may be more serious. 

(4) The number of disease control institutions has decreased, and some places have even merged disease control institutions in the name of reform. In 2003, there were 3,584 national centers for disease control and prevention (epidemic prevention stations), and by the end of 2019, there were only 3,403 centers, a decrease of 181. In July 2018, Liaoning Province issued the red-headed document "Optimization and Integration Plan of Provincial Public Welfare Institutions", which reorganized and integrated the provincial and municipal disease control and health supervision departments. After the integration, only provincial disease control remained, and disease control and health supervision institutions below the provincial level were integrated and will no longer exist. 

(5) The county-level CDC is beset with "diseases" and its business development is stagnant and retrogressive. Professional and technical personnel are in short supply, and there is a serious shortage of staff; Aging infrastructure and insufficient investment; The channel of working funds is single; Lack of incentive and restraint performance appraisal system, lack of enthusiasm for disease control cadres.    

Reform is imperative! How to change it?   

Gao Fu suggested.   

According to the report of China Youth Daily on May 27th, Gao Fu, director of China Center for Disease Control and Prevention, who attended the third session of the 13th Chinese People’s Political Consultative Conference, called for speeding up the reform of the disease control system. He proposed to strengthen the core competence of disease control institutions and improve their "professional voice".   

He said that the new pneumonia epidemic has exposed the shortcomings of China’s major epidemic prevention and control system and public health system construction. As the main force of epidemic prevention and control, CDC has not fully played its role in early warning and monitoring, epidemiological investigation, and the proposal and implementation of prevention and control measures, and is faced with problems such as insufficient capacity, professional voice can not meet the requirements of modern disease prevention and control management and the increasingly diverse needs of the masses. The existing problems include: the CDC’s "unequal power and responsibility", the responsibility to put forward prevention and control strategies, the lack of decision-making power and discourse power to deal with the epidemic, and the "disconnection between administrative decision-making and technical strategies", and the CDC experts can only exercise the right of suggestion and cannot participate in decision-making; There is only a relationship of guidance and guidance between the superior and the subordinate disease control institutions, which makes it difficult to form an effective joint force in dealing with the epidemic situation. The division of labor and cooperation mechanism between disease prevention and control institutions and medical institutions is not perfect.

The administrative functions of disease prevention and control are decentralized. The disease prevention, control and emergency functions of the national health administrative department are scattered in many departments, such as disease prevention and control bureau, medical management and emergency office. There is a lot of interference in the details of prevention and control, and there is no comprehensive coordination. According to Gao Fu, from 2010 to 2018, the total number of CDC staff at all levels in China decreased by 3.9%, among which the number of professional technicians mainly practicing doctors decreased by 10.8%.

In terms of funds, the share of medical and health expenditure of CDC decreased from 2.9% to 2.4%. He stressed that the key to the reform of the disease prevention and control system "is not whether it has administrative power, but that the technical work is not subject to administrative intervention and maintains its independent technology and authority." To this end, he suggested clarifying the responsibilities of the administrative department and the technical department.

According to the law, CDC has the right to formulate and publish prevention and control strategies and technical plans, and is responsible for monitoring, investigating, handling, early warning and evaluating the epidemic situation. He suggested, "Give the CDC decision-making power in the field of professional affairs and reduce the micro-management and direct management of the CDC by the health administrative department. Explore the establishment of a mechanism for reporting public health work and major issues directly to the leaders in charge of the government, and directly release epidemic information with the authorization of the government. " In addition, he suggested strengthening the awareness and ability of coordination, strengthening the management of higher-level disease control institutions to lower-level disease control institutions, implementing vertical business management of major public health service projects under the jurisdiction of the central government, and strengthening the national disease control system. On the afternoon of June 2nd, General Secretary of the Supreme Leader presided over a symposium of experts and scholars and delivered an important speech. He emphasized that the disease prevention and control system is an important guarantee for protecting people’s health, ensuring public health safety and maintaining economic and social stability. We should base ourselves on more accurate and effective prevention, and intensify reform in rationalizing the system and mechanism, clarifying the functional orientation, and improving professional ability.

It is necessary to establish a stable investment mechanism for public health undertakings, improve the basic conditions for disease prevention and control, and improve public health services.

It is necessary to optimize and improve the function setting of disease prevention and control institutions and establish a division of labor and cooperation mechanism linked up and down.

It is necessary to strengthen the capacity building of national disease prevention and control institutions and strengthen their technology, ability and talent reserve. It is necessary to improve the linkage mechanism between disease control institutions and urban and rural communities, strengthen the disease prevention responsibilities of township hospitals and community health service centers, and consolidate the grassroots foundation of joint prevention and control.

It is necessary to innovate the coordination mechanism of medical care and prevention, and establish a mechanism of mutual restriction between personnel communication, information communication, resources communication and supervision and supervision.

It is necessary to strengthen the construction of disease control talent team, establish a talent training and use mechanism that adapts to the modern disease control system, and stabilize the grassroots disease control team.

It is necessary to build a number of high-level public health colleges and focus on cultivating talents who can solve practical problems such as pathogen identification, epidemic situation research and transmission law research, on-site epidemiological investigation and laboratory testing.

It is imperative to strengthen the ability of early monitoring and early warning, improve the monitoring system of infectious diseases and public health emergencies, improve the monitoring mechanism of unexplained diseases and abnormal health events, improve the sensitivity and accuracy of evaluation and monitoring, establish a multi-point trigger mechanism of intelligent early warning, improve the multi-channel monitoring and early warning mechanism, and improve the ability of real-time analysis and centralized judgment.

It is necessary to strengthen the construction of laboratory testing network and improve the ability of infectious disease detection. It is necessary to establish a collaborative monitoring mechanism between public health institutions and medical institutions, give play to the role of grass-roots sentinel, and achieve early detection, early reporting and early disposal.

It is necessary to improve the response plan system for public health emergencies, set up health emergency teams by classification, and cover the fields of situation judgment, epidemiological investigation, medical treatment, laboratory testing, community guidance, and material deployment. It is necessary to strengthen the knowledge reserve and training exercises of grassroots health personnel and enhance the ability of pre-disposal. It is necessary to carry out in-depth publicity and education on health emergency knowledge, and improve the people’s awareness of public health emergencies and their ability to prevent self-help and mutual aid.

Party committees and governments at all levels should establish regular research and deployment of health and health work mechanisms such as prevention and control of major epidemics, so as to ensure clear instructions, orderly systems, smooth implementation.

Hubei exploration   

On June 10th, the Seventh Plenary Session of the 11th CPC Hubei Provincial Committee was held in Wuhan. The meeting discussed the Opinions of Hubei Provincial People’s Government on Promoting the Reform of Disease Prevention and Control System and Public Health System, and decided to take the lead in domestic exploration, plan the reform of medical and health system as a whole, systematically reshape the public health system, and improve the system and mechanism of major epidemic prevention and control. Ying Yong, secretary of Hubei Provincial Party Committee, attended the meeting and delivered a speech. He pointed out that the prevention and control of the epidemic situation reflected the problems of imperfect network, unclear functions and separation of medical care and prevention in our province.

It is necessary to reform the disease control system in accordance with the unified arrangements of the CPC Central Committee. Straighten out the system and mechanism, clarify the functional orientation, and enhance the professional ability. Strengthen the administrative functions of disease control institutions, implement the responsibility of supervision and supervision, and the main person in charge of disease control institutions is also a member of the health department at the same level. 

Explore and promote the "first-class security and second-class management", implement the "two permits" in detail, allow disease control institutions to break through the current wage control level of public institutions, allow medical and health technical services to be provided on the basis of completing approved tasks, and further stimulate the endogenous motivation of disease control institutions. Strengthen the construction of disease control talents. Disease control institutions should strengthen monitoring and early warning functions, and effectively strengthen the construction of hardware facilities and infectious disease detection capabilities. The coordination of medical care and prevention should be the top priority.

Try out the system of "chief public health officer" in the health department. Formulate a list of public health responsibilities, improve public health service projects, and innovate the coordination mechanism between disease control institutions and medical institutions around the establishment of a mechanism of mutual restraint between personnel communication, information communication, resources communication and supervision and supervision. It is imperative to enhance early monitoring and early warning capabilities. The premise of epidemic monitoring and early warning is that the sources of epidemic information are unblocked and data are shared openly. It is necessary to improve the monitoring system of infectious diseases and public health emergencies, and establish a multi-point trigger mechanism of intelligent early warning to achieve early detection, early reporting and early disposal. 

Lao Xu suggested.   

(a) the implementation of epidemic reporting according to law, reduce human intervention, give full play to the state invested heavily in the establishment of the network is said to be relatively advanced epidemic reporting system. (two) strengthen the training of disease prevention and control professionals. First of all, we should plan the disease prevention and control system and the construction of talent team from the strategic height of national long-term stability. Huang Qifan once suggested that the training of public health and epidemic prevention talents must be expanded in scale and improved in quality, and double-class universities should be encouraged to set up high-quality public health colleges, rather than only medical colleges to set up this major; Build a national key university of public health and epidemic prevention, such as "China University of Public Health", pay equal attention to teaching and scientific research, cultivate high-end public health and epidemic prevention talents for the country, and concentrate on establishing a research system and laboratory system of public health and epidemic prevention, gather high-end scientific and technological talents from all over the world, and undertake cutting-edge research work in the field of public health in China and even the world. 

(3) In deepening the reform of the medical and health system, we should make overall plans for the reform of the disease control system. In particular, it should be noted that the disease control system can only be strengthened, not weakened; The talent team can only be steadily strengthened, and it cannot be floating and brain drain; The reform of disease control can only take a more professional road, establish the authority of disease control because of its specialty, and increase the right to speak in decision-making, instead of taking an administrative road. Disease prevention and control should be incorporated into the national security strategy, and an elite team that is professional, authoritative and trusted by all parties should be established, rather than an administrative grease. 

(four) pay close attention to the capacity building of grassroots disease control institutions. Create the first line of defense for disease prevention and control.  

The construction site became a "nightmare" for unmanned vehicles, and Google Waymo stumbled so much that he was interviewed.

Robotaxi, fire and theft prevention "construction site". Waymo fell.

The North American regulatory authorities have just opened an investigation into Waymo unmanned vehicles, because they received a series of related accident reports.

Some hit parked cars on the side of the road, some hit static obstacles, blocked traffic … and an unusual high-frequency scene:construction site.

In about three months, Waymo accumulated and reported 22 accidents, which attracted the attention of the National Highway Traffic Safety Administration.

According to NHTSA documents, these accidents include collisions between Waymo unmanned vehicles and static and semi-static objects (such as doors), collisions with parked vehicles and violations of traffic safety control devices.

Among them, the official special explanation of "violation of traffic safety control devices" is a key investigation direction, and a typical scene isAbility of automatic driving system to detect and identify traffic cones/ice cream cones.

This point is rare. Because many of the 22 accidents reported this time involve the same scene- construction site.

For example, last month,Waymo Robotaxi with 6 vehicles in formation.After work, I went back to the parking lot. As a result, I encountered temporary traffic control at the construction site and was directly stuck in the temporary traffic area surrounded by ice cream cones, causing traffic congestion for about half an hour.

Netizens with local life experience immediately recognized that this is the ramp at No.101 Potrero Avenue in San Francisco, where the Waymo unmanned vehicle was stuck, which happened to be the high-speed entrance.

Finally, it was the driver’s brother on the road who directly got off the driver to move the ice cream cone, and the team behind him bypassed several "paralyzed" unmanned vehicles in turn.

Waymo made a simple statement to the effect that people were sent to the scene to move the car within 30 minutes, without causing any casualties or property losses, and will cooperate with the investigation later.

But in the construction site of Phoenix, it is not so lucky.

The same Waymo unmanned vehicle ignored the construction area surrounded by the ice cream cone and rushed directly into the construction site.

Fortunately, the speed was not fast enough to hit people, but the vehicle itself and the construction site suffered losses to varying degrees.

There are many accidents like this. Every time an unmanned vehicle "rushes into the construction site", it will go viral on the Internet.

The netizen summed it up vividly:The traffic cone is Robotaxi’s kryptonite.Now, the miraculous automatic driving will be finished if it meets the traffic cone on the closed road.

Huh? It doesn’t seem to be the same as the video officially shown by Waymo.

Waymo The fifth generation autopilot system bypasses the construction area.It has been specifically analyzed as a technical highlight.

In the official Demo, the scene faced by unmanned vehicles is more complicated, except for traffic cones, irregular areas and workers walking back and forth.

Of course, the Waymo unmanned vehicle completed a series of evasive and detour actions effortlessly and successfully passed the construction area:

What is amazing here is that the Waymo unmanned vehicle seems to be able to understand the body language of human traffic command, let it stop and let it go, not just based on road conditions.

How did you do that? Maya Kabkab, the engineer in charge of the prediction algorithm of Waymo, briefly explained to the effect that in the fifth generation technology, Waymo strengthened the ability to understand different objects and targets and the ability to identify passable areas, which enabled the system to plan the passable route better.

The core is to replace CNN with a new model, VectorNet, to extract sensor and high-precision map information.

To put it simply, high-precision maps and sensor input information are represented as points, polygons or curves, while VectorNet represents all road features and trajectories of other objects as corresponding vectors. Based on this simplified view, VectorNet can extract the information of each vector and learn the relationship between different vectors.

The advantage is that VectorNet takes up less computing resources than CNN, produces results faster, and theoretically can extract key scene information more clearly.

But VectorNet still has no core to solve the "construction site" problem-

The "construction site" itself is an exception to high-precision maps.It is impossible to update synchronously, and it can only be sensed by sensors in real time.

However, the data of sensors are transmitted among different sub-models in turn, so it is difficult to completely avoid information loss.

Robotaxi is frequently stuck in the construction site, and the direct reason is the false detection of traffic cones and alien objects.

The underlying reason is thatThe upper limit and ceiling of the existing capacity of the traditional autonomous driving technology paradigmIt is difficult to cover all corner case on the road.

Therefore, whether the construction site can be avoided smoothly has become a probabilistic event: the official Demo has been carefully tested and repeated, which is no problem; If you only measure it on the road, you can only eat according to the weather.

"Never decide quantum mechanics when something happens" is a ridicule.

However, in the field of autonomous driving, if something is undecided, it is indeed possible to "end-to-end".

The so-called "end-to-end" is aimed at the traditional technology paradigm, in which the perception, decision-making, regulation and control of autonomous driving are independent of each other. The data collected by the sensor needs to pass through this series of different algorithm modules before it can finally become an operation instruction.

The information between each independent module is transmitted step by step. In this process, there will inevitably be information loss and errors, and the errors of the previous module will affect the next one, and the information errors between multiple modules will continue to accumulate, thus affecting the overall effect of the automatic driving scheme.

Whether it is pure visual perception or fusion perception, the root of "false detection and missed detection" is here.

Of course, there is also a corresponding solution, that is, through the rules of human handwriting, try to patch it to improve the reliability of perceptual recognition. For example, you can recognize cars and people, but you can’t recognize "people standing in front of cars". That’s easy. Why don’t you just build a separate data set for such targets and use it to train the model?

This is the so-called perceptual "white list" mechanism.

But the problem is that it is difficult to enumerate all kinds of traffic targets and scenes. This time, the problem of "people in front of the car" has been solved, but what if the car changes from a passenger car to a big truck? Or does a person become an adult and take care of children?

The same is true for Robotaxi’s construction site problem. The construction site may appear temporarily and refresh randomly, and it will not limit the area and time, and the construction and construction roadblocks of each construction site are different …

Therefore, a new algorithm paradigm-end-to-end algorithm model is needed to realize the lossless transmission of information from the beginning of perception and make the system truly understand the environment.

The two terminals refer to the data input terminal and the instruction output terminal respectively, and the middle is no longer divided into several independent modules.

The end-to-end model can transfer and generalize its learned abilities and skills to other scenes through a completely data-driven mode, independently and efficiently solve all kinds of new long tail problems in the berthing scene, have faster iterative efficiency and effectively reduce the cost of opening a city.

In layman’s terms, it is to let AI Division learn the mature driving behavior of human beings, see a scene and make corresponding countermeasures. In fact, "end-to-end" has touched the threshold of AGI.

In 2016, the end-to-end model was first proposed by NVIDIA. But the real mass production practice began in these two years. At present, only Tesla’s FSD and China’s AI players’ CVPR 2023 best papers-UniAD.

The Smart Car Reference also asked the opinions of the two domestic self-driving head players about the construction site problems encountered by Waymo.

Horizon from the perspective of engineering practice, think:

AutopilotSite problems and end-to-end technology paradigms are not bound.. Theoretically speaking, the problem can also be solved if the perception ability is strong enough and the perception white list is rich enough.

But obviously, end-to-end autonomous learning ability and humanoid thinking will solve this problem on a larger scale and more efficiently.

And Shang Tang’s view is more from the "first principle", and the relevant technical experts of Jueying Zhijia think:

Do not evaluate specific case. However, the perception of the traditional rule-based intelligent driving scheme still artificially defines the elements and abstracts the perceived information, which will lead to the loss and omission of the information transmission process and make it difficult for the perceptual decision-making module to make correct decisions. End-to-end is a neural network, which can input and transmit the information of the external environment without loss, understand the external traffic environment more accurately and completely, and make plans and decisions.

The rule scheme can solve a scenario by adding rules and patches. But there is not only one such scene, it is infinite. With enough data for learning and training, the end-to-end solution can think and drive like a human and solve more similar corner case by itself.

To sum up, Horizon and Shang Tang have different expressions, but the core is the same, and they all agree.End-to-end is the most effective way to solve Robotaxi site problems.. At the same time, it is the most efficient way to solve all kinds of long tail problems of autonomous driving.

By the way, I put forward UniAD’s CVPR 2023 best paper, which was written by scholars from Horizon and Shang Tang.

End-to-end innovation of traditional technology paradigm has given all players new opportunities: better intelligent driving experience, lower maintenance and generalization costs, and more competitive cost of autonomous driving scheme.

However, the price is the modular and rule-driven technical system in the past, which must be overthrown and reconstructed.

Waymo, the absolute leader of autonomous driving in the past, is now caught in the dilemma of "construction site", which further proves that the track of autonomous driving is "water is impermanent and soldiers are unpredictable":

Old stars may have their advantages reset to zero, and "latecomers" will also gain the lead.

Shi Yunyu, an 80-year-old academician of the Chinese Academy of Sciences and a professor at the School of Life Sciences of the Chinese University of Science and Technology —— Pursuing the mystery of b

  Character business card

  Shi Yunyu: Academician of China Academy of Sciences, biophysicist and structural biologist, professor and doctoral supervisor of China University of Science and Technology. Born in Chongqing in April 1942, she was admitted to the Department of Biophysics of the Chinese University of Science and Technology in 1960. Since then, she has formed an indissoluble bond with life science. Over the years, Shi Yunyu has been sticking to the front line of scientific research, using structural biology methods to study the molecular mechanism of gene expression regulation and cell fate determination, and has made many innovative achievements, making contributions to China’s biological nuclear magnetic resonance research in the world.

  Dressed in a cloth and with silver hair, Shi Yunyu clicked the mouse neatly in the office, and the three-dimensional structure of protein jumped into his eyes: "The world of biomacromolecules is full of unknowns. We have encountered many difficulties and challenges in the research process, but we must not give up lightly." Shi Yunxi said.

  My father’s words and deeds, what he saw and heard on his way to school, let the seeds of scientific research serve the country take root.

  Shi Yunyu has always had a scientific research dream! Whether she leaned against her father when she was young, listened to him describe the colorful physical world, or came into contact with the frontier of life science on the long way to school, the idea of serving the country through scientific research always lingered in her mind … …

  Shi Yunyu was born in the era of war. The experience of being displaced as a child made her realize that personal destiny is always closely linked with the destiny of the country and the nation. Father Shih-Yuan Sze is a doctor of physics under the guidance of Madame Curie. After graduation, Shih-Yuan Sze, then 25, returned to China to teach and became one of the pioneers of nuclear physics research and higher education in China. In Shi Yunyu’s view, the spirit of serving the country through scientific research is vividly displayed in his father; His words and deeds also inspired Shi Yunyu’s enthusiasm for scientific research.

  With a passion for natural science, Shi Yunyu was admitted to China University of Science and Technology in 1960. At that time, biophysics was a new discipline and the education system was not yet mature. "Academician Bei Shizhang, then head of the biophysics department of the Chinese University of Science and Technology, believed that the curriculum should be ‘ Four unlike ’ Let students lay a good foundation in mathematics, physics, chemistry and biology. " Shi Yunyu said that it is the solid basic course study that lays a solid foundation for his future scientific research work.

  In the classroom, the days when scholars such as Qian Xuesen, Hua Luogeng and Yan Jici gave lectures to everyone made her remember vividly … … Shi Yunyu said: "How fortunate to be able to feel the deep patriotic feelings of the older generation of scientists at close range!" In the auditorium, everyone gathered around a black-and-white TV set and rejoiced at the China athletes winning the world table tennis championship. She still can’t forget it: "When I was young, everyone’s enterprising state always inspired me and made me determined to contribute to the construction of the motherland with my own scientific research results."

  After graduating from college, Shi Yunyu was first assigned to work in the former Institute of Traditional Chinese Medicine of the Ministry of Health; In 1970, she returned to China University of Science and Technology to teach, and before long, she moved south from Beijing to Hefei, Anhui.

  Shi Yunyu undertook the task of relocating instruments and equipment to the south. Together with her colleagues, she moved boxes full of equipment from the teaching building to the station in Beijing, and then moved them from the station to the teaching building … …

  Engaged in computer molecular dynamics simulation of biological macromolecules earlier; Leading the establishment of the key laboratory of structural biology of Chinese Academy of Sciences

  The southward migration of China University of Science and Technology has gone through hardships, with the loss of scientific research equipment and weak teaching strength … … "Fortunately, the school later took a series of new measures and gradually got on the right track." Shi Yunyu said that the school provided opportunities for young teachers to go abroad for further study, and she became the first young teacher in the Biology Department of the Chinese University of Science and Technology to pass the examination of the Ministry of Education. She went abroad twice for further study, engaged in computational biology research and biological nuclear magnetic resonance spectroscopy research, and learned the theoretical and experimental methods of studying the structure and function of biological macromolecules with molecular dynamics and two-dimensional nuclear magnetic resonance spectroscopy. Shi Yunyu said: "The experience of studying abroad has broadened my scientific research horizons and urged me to work harder to acquire knowledge."

  In the 1970s, Shi Yunyu and his colleagues were eager to keep up with the pace of international academic circles and carry out cutting-edge research on biomacromolecules in the University of Science and Technology of China, but they lacked funds and instruments. In order to promote the project quickly, Shi Yunyu and his colleagues went all over the library in Shanghai, searched for literature and materials, and racked their brains for two weeks before finishing the application for the National High-tech Research and Development Plan.

  At that time, there were three subjects selected by the Biology Department of the Chinese University of Science and Technology, and the "New Technology Research of Molecular Design in protein" which Shi Yunyu was in charge of was one of them. Since then, she began to engage in computer molecular dynamics simulation of biological macromolecules and became one of the pioneers in this field in China. The project "Computer Simulation of Biomolecular Structure and Dynamics" led by Shi Yunyu won the second prize of the Natural Science Award of China Academy of Sciences in 1996 and the third prize of the National Natural Science Award in 1999.

  In the early 1990s, Shi Yunyu’s laboratory was supported by the Chinese Academy of Sciences and bought the first 500 MHz nuclear magnetic resonance spectrometer, which can be used for the solution structure of biological macromolecules. However, when the experiment was really carried out, there were still many difficulties … … Her attitude is firm: "scientific research should be devoted, able to withstand loneliness and twists and turns." The research group led by Shi Yunyu analyzed the solution structures of a series of important protein, and revealed the protein interaction and its functional significance. She also led the establishment of the Key Laboratory of Structural Biology of Chinese Academy of Sciences, and later became an important part of Hefei National Research Center for Microscale Material Science.

  Do popular science for primary and secondary school students, teach basic courses for undergraduates, and train more young scientific research talents.

  Shouxian County, Anhui Province, No.1 Middle School. On the stage, Shi Yunyu held a microphone and explained his own experience and knowledge of life science. Under the stage, the students were absorbed and deeply attracted by the biomacromolecule world she described. From the stimulation of scientific interest to the choice of scientific research direction, from laying a solid foundation to the enthusiasm of serving the country, in an hour and a half, Shi Yunyu planted the seeds of science in the hearts of children … …

  Although he is 80 years old, Shi Yunyu still walks into primary and secondary schools many times to give lectures on popular science to students. "Being exposed to scientific knowledge since childhood has aroused my curiosity and embarked on the road of scientific research; I also want to pass this enthusiasm on to the children. " Shi Yunyu hopes to open a window of science for children.

  Shi Yunyu remembers: In 2019, at Huangtugang Town Central Primary School in Macheng, Hubei Province, she gave a popular science class on "Hemoglobin and Hemoglobin Diseases" to children in Dabie Mountains. Her classmates’ eyes are full of thirst for scientific knowledge, which deeply touched her, so she likes to go out of campus and go to the mountains … …

  In the College of Life Sciences of the Chinese University of Science and Technology, in order to strengthen the basic education of undergraduates, Shi Yunyu insisted on giving general biology classes to freshmen for many years. Shi Yunyu said that for interdisciplinary subjects, basic courses are very important. "Teaching is the bounden duty of teachers, and I want to train more talents for science." As the first dean of the School of Life Sciences of the Chinese University of Science and Technology, together with her colleagues, she took the lead in establishing a complete teaching system of structural biology and computational biology in the Chinese University of Science and Technology, and specially invited experts from the Institute of Biophysics of the Chinese Academy of Sciences to teach students and trained a group of young academic leaders working in interdisciplinary fields such as computational biology and structural biology.

  Today, with her silver hair, she still rushes to work in the laboratory every day. In school, when she meets Shi Yunyu, the students always call her "Grandma Shi" in a friendly way. At present, "Grandma Shi" has begun to study the structure of protein related to aging and degenerative diseases and the molecular and cellular mechanism of diseases. In addition, she is actively promoting the research of artificial intelligence and biomedicine. She believes that every new field has a lot of knowledge to learn, and the happiness of mountaineering is not only the moment when you reach the top of the mountain, but also in the process of continuous climbing.

  ■ Reporter’s Notes

  Research never stops, only lifelong learning.

  During the interview, Shi Yunyu was full of interest when he mentioned the frontier development in the field of life sciences … … At the age of 80, she is willing to study with young people while cultivating scientific research talents. In Shi Yunyu’s view, being able to explore the mysteries of the biomacromolecule world with students is both happy and fulfilling. Young people always learn new things faster, and they can experience the taste of being a student when they meet something she doesn’t quite understand.

  Life science is closely related to population health, medicine and ecology, and the life world is full of many unsolved scientific problems. For Shi Yunyu, research never stops, only lifelong learning. It is countless scientists, like her, who keep their enthusiasm for learning and keep climbing up, which makes scientific research full of vitality … …

Report on the Development Trend of Agriculture and Rural Areas in China in 2022-Ensuring Priority Development of Agriculture and Rural Areas (11th Edition of Economic Daily on January 21st)

  Under the background of stable macroeconomic operation, China’s agricultural and rural reform and development have achieved remarkable results, and the role of agriculture as a ballast stone for economic and social development has become increasingly significant. This report reviews the development of China’s agriculture and rural areas in 2021, analyzes the important opportunities and challenges faced in 2022, and predicts its development trend. On this basis, it puts forward relevant countermeasures and suggestions based on the hot issues that need attention in the process of agricultural and rural economic and social development.

  Agriculture grew steadily and grain reached a new high.

  2021 is the first year of the "14th Five-Year Plan". China has overcome the adverse effects of the COVID-19 epidemic and the complicated international economic situation, the overall economy has recovered, agriculture has continued to maintain high-quality and steady development, farmers’ living standards have been continuously improved, and the rural landscape has been further improved.

  The agricultural economy grew steadily and the grain output reached a new high. In 2021, the added value of the primary industry increased by 7.1% over the previous year, reaching 8,308.6 billion yuan, accounting for 7.26% of the GDP, which was lower than that in 2020. In the first three quarters, the total output value of agriculture, forestry, animal husbandry and fishery reached 9,286.34 billion yuan. Among them, the total output value of agriculture is 4,667.11 billion yuan, the total output value of forestry is 384.13 billion yuan, the total output value of animal husbandry is 2,832.90 billion yuan, and the total output value of fishery is 912.96 billion yuan.

  The comprehensive agricultural production capacity has been continuously improved, and the production of important agricultural products such as grain has made steady progress. In 2021, 100 million mu of high-standard farmland was built nationwide, and the mechanization rate of crop cultivation and harvest exceeded 72%, of which the comprehensive mechanization rate of wheat cultivation and harvest reached over 95%. The national total grain output reached a new high, reaching 1,365.7 billion Jin, an increase of 26.7 billion Jin over the previous year and a year-on-year increase of 2%. It remained above 1.3 trillion Jin for seven consecutive years, achieving "18 consecutive years of prosperity". The national grain planting area was 1.764 billion mu, an increase of 12.95 million mu over the previous year, with a year-on-year increase of 0.7%, which maintained the growth trend for two consecutive years.

  The agricultural product market operated smoothly, and the producer price dropped slightly. Basic self-sufficiency of grain and absolute safety of rations are the general pattern of grain supply and demand. Judging from the market situation of major cereals, the supply and demand of wheat and rice are basically stable, and the domestic supply of corn presents a certain gap. With the increasing demand for meat, eggs, milk and other products, the demand for feed grain represented by corn is also increasing. In addition, corn is still in the critical period of agricultural production structure adjustment. To some extent, China still needs to increase the import of corn and feed grain to meet the demand. Generally speaking, China’s annual rice imports account for about 2% of domestic production, wheat imports account for about 6% of domestic production, and corn imports account for about 10% of domestic production. Grain imports mainly play a role in meeting differentiated needs.

  In terms of livestock products, the production capacity of live pigs has fully recovered, and the supply of pork market is relatively sufficient in 2021. Especially since last October, the orderly development of the second round of central and local reserve meat storage has played an important role in ensuring the stability of the pork market and the interests of aquaculture enterprises.

  In 2021, the producer price of agricultural products fell by 2.2%. The overall price of grain increased greatly, reaching 13.8%, among which wheat and rice increased slightly, 6.6% and 1.9% respectively, while corn increased by 25.5%. The overall price of livestock products decreased by 17.9% year-on-year, mainly due to the decline in the price of live pigs, which decreased by 35.1%; However, the prices of cattle, sheep and eggs have increased in different proportions, among which the price of eggs has increased by 15.5%, which is higher than that of cattle and sheep.

  Farmers’ income and consumption increased rapidly.

  Farmers’ income grew steadily, and consumption increased steadily. In 2021, the per capita disposable income of rural residents was 18,931 yuan, a real increase of 9.7% after deducting the price factor, which was 2.6 percentage points faster than that of urban residents. From the perspective of income composition, farmers’ income mainly includes wage income, net operating income, net transfer income and net property income. In the first three quarters of 2021, the four types of income all increased. Among them, wage income is the largest source of farmers’ income, which is 6325 yuan, with a nominal increase of 15.3%, accounting for 46.1% of farmers’ disposable income; The net operating income is 4042 yuan, with a nominal increase of 6.7%, accounting for 29.4%, which is the second largest source of farmers’ income; The net transfer income reached 3002 yuan, a nominal increase of 11%, accounting for 21.9%; The net income of property was 357 yuan, with a nominal increase of 10.7%, accounting for 2.6%.

  In the first three quarters of 2021, the per capita consumption of rural residents was 4.7 percentage points higher than that of urban residents, and there was still a gap between the consumption level of rural residents and urban residents. In the expenditure structure of rural residents, the consumption of basic necessities such as food, clothing, housing and so on has grown steadily, among which the per capita expenditure on food, alcohol and tobacco accounts for 32% and the per capita expenditure on housing accounts for 21%. Due to the scientific coordination of epidemic prevention and control and economic and social development in various regions and departments, the impact of the epidemic has been basically overcome. Consumer spending on services and other supplies has shown a rapid growth trend throughout the year, but it has not yet recovered to the same level in 2019.

  The level of rural informatization has improved rapidly, and agricultural production has started to be digitized. The COVID-19 epidemic has made the role of rural e-commerce more prominent. According to the statistics of the Ministry of Agriculture and Rural Affairs, at present, the coverage rate of administrative villages of e-commerce service stations in China is about 80%, and the online retail sales of agricultural products in counties exceed 300 billion yuan, which is growing rapidly. Relevant research shows that the number of Taobao villages has exceeded 7000 in 2021. The overall promotion of rural revitalization will accelerate the popularization and sinking of digital technology and accelerate the digitalization of rural industries. In the field of smart agriculture, the digitalization of agricultural production is in the ascendant, and the construction of the whole industrial chain of single product big data, such as oil, natural rubber, cotton, soybeans and other products, has started, and the application fields of big data systems have been continuously expanded.

  The reform of rural collective property rights has completed the phased task, and the collective economy has become a new growth point. The task of rural collective property rights reform has been basically completed nationwide, and rural asset resources have been greatly revitalized through measures such as clearing assets, defining members, quantifying operating assets and establishing economic (stock economy) cooperatives. According to the statistics of the Ministry of Agriculture and Rural Affairs, by 2021, nearly 900,000 collective economic organizations at the township, village and group levels have been established in China, and the collective book assets have been checked and verified to be 7.7 trillion yuan (excluding resource assets such as land), including 3.5 trillion yuan of operating assets. The endogenous kinetic energy of rural development has been significantly improved, and the collective economy has become a new growth point, laying a solid foundation for achieving the goal of common prosperity.

  The pressure of farmland protection has increased.

  During the "14th Five-Year Plan" period, the key and difficult points of China’s economic and social development are still "agriculture, rural areas and farmers", and the potential stamina is also "agriculture, rural areas and farmers". In the face of the unprecedented changes in the world in the past century, China’s agricultural and rural development is facing new opportunities.

  The steady macroeconomic recovery has provided a good environment for China’s agricultural economic development. The World Bank and the International Monetary Fund estimate that the growth rate of China in 2022 will exceed the world average and developed economies. Domestic consumption is also gradually recovering. If the epidemic can be completely ended in 2022, domestic consumption will be revived and the economic growth rate is expected to return to the pre-epidemic level.

  The further deepening of international cooperation provides an opportunity for the development of international trade in agricultural products. The "Belt and Road Initiative" has brought great impetus to China’s agricultural international cooperation. In the first half of 2021, the trade volume of goods between China and countries along the Belt and Road reached 5.35 trillion yuan, a year-on-year increase of 27.5%, which was higher than the overall growth rate of China’s foreign trade, accounting for 29.6% of the total foreign trade. Among them, agricultural trade accounts for about a quarter of the total trade. RCEP (Agreement on Regional Comprehensive Economic Partnership), which came into effect on January 1st, 2022, will undoubtedly provide new opportunities for China to expand international cooperation in agricultural economy and trade.

  With the promotion of rural revitalization strategy, the pattern of giving priority to agricultural and rural development has gradually taken shape. Infrastructure construction is speeding up again, and government investment and social capital will be invested more in agriculture and rural areas for land, water conservancy, seeds, digitalization, logistics facilities, especially cold chain construction.

  Agricultural and rural development also faces several challenges.

  Ensuring the quantity and quality of cultivated land is still a great challenge for China’s economic development at present. At present, the cultivated land in China is about 1.92 billion mu, which is 113 million mu less than the 2.03 billion mu cultivated land in the second national land survey 10 years ago. In addition, China’s urbanization continues, the ecological environment pressure has not been fundamentally alleviated, and the pressure on cultivated land protection is increasing. To ensure food security, while keeping the red line of cultivated land firmly and ensuring the area of cultivated land, more effective measures should be taken to resolutely stop the "non-agricultural" and prevent the "non-grain" of cultivated land.

  The overall cost of agricultural products is increasing, but the price of agricultural products is weak or fluctuates greatly. Since the new century, China’s agriculture has gradually entered a high-cost stage. From the perspective of planting industry, the cost of agricultural input and labor input is increasing, which has seriously affected farmers’ enthusiasm for growing grain. Land rents are also rising. According to the survey of major grain producing areas, the land rent in Northeast China ranges from 500 yuan/mu to 600 yuan/mu, while in central provinces it ranges from 400 yuan/mu to 600 yuan/mu, while in some eastern coastal provinces the average land rent reaches about 1000 yuan/mu, which further squeezes the profit space of transferring land management rights to grow grain.

  The relationship between supply and demand of important agricultural products is in a tight balance. Soybean still needs to rely on imports to meet the demand. In 2021, soybean imports will account for nearly 60% of the total grain imports, but the rations are absolutely safe.

  It is worth noting that there is still great uncertainty in the international environment, and the protectionist policies of developed countries are on the rise repeatedly, which poses certain challenges to China’s food security and sustainable agricultural development.

  It should also be noted that China’s urbanization is still continuing, and the population is accelerating to gather in major developed areas. At present, the resident population in cities and towns has exceeded 900 million. The resident population in rural areas continues to decrease, and the aging trend is still intensifying, which will be an important problem that must be solved in rural revitalization in the future. In recent years, the income gap between urban and rural areas in China has been narrowing, but the per capita disposable income of rural residents still lags behind that of urban residents. In 2021, the income ratio between urban and rural residents was 2.50, which was lower than the previous year, but the absolute value of the income gap between urban and rural areas was still 28,481 yuan. The reality that the income gap in rural areas has not been significantly alleviated will also affect the realization of the goal of common prosperity.

  The momentum of sustained and rapid development in 2022

  Combined with the employment population and social fixed assets investment in agriculture, industry, agricultural products processing and service industries in the last 10 years from 2011 to 2020, a prediction model was established according to the latest input-output table of 135 departments in China, and the report results were simply averaged by setting different simulation schemes, so as to judge the development trend of agriculture and rural areas in China in 2022 as follows.

  It is expected that the economy will continue to grow. In 2021, China actively responded to the impact of the epidemic, and GDP growth exceeded the pre-epidemic level, from recovery to high-quality growth. It is estimated that the contribution of primary industry, secondary industry and tertiary industry to GDP will reach 0.4%, 1.9% and 2.8% respectively when the economic growth rate exceeds 5.0% in 2022.

  It is estimated that the growth rate of agricultural added value will be 5.67%, maintaining a rapid and stable growth rate. The proportion of agricultural added value has increased, which may reach about 8%. The added value of processing industries (grain grinding products, feed processed products, vegetable oil processed products, sugar materials and sugar products, meat processed products, aquatic products processed products, vegetables and fruits processed products, dairy products and tea) with main agricultural products as raw materials will continue to grow, with the growth rate reaching about 3.0%, accounting for about 1.6% of GDP.

  It is estimated that the trade volume of agricultural products will reach US$ 350 billion, of which the export volume of agricultural products will reach US$ 80.7 billion and the trade deficit of agricultural products will reach US$ 188.6 billion, up nearly 40% year-on-year. Imports of edible oil seeds, edible vegetable oils and livestock products account for about 50% of domestic agricultural products imports.

  It is estimated that per capita disposable income will exceed 40,000 yuan, including 20,300 yuan in rural per capita disposable income, which is estimated to increase by 8% year-on-year, 2 percentage points higher than that of urban residents. It is estimated that the per capita consumption expenditure of residents will be 24,000 yuan in 2022, an increase of 5.3% over 2021; The average consumption expenditure of rural residents is about 15,000 yuan, an increase of 6.8% over 2021 and 2.4 percentage points higher than that of urban residents.

  On the whole, it is predicted that the development of agriculture and rural areas in China will be faster than other departments in 2022, the strategy of giving priority to the development of agriculture and rural areas will continue to advance steadily, and the gap between urban and rural areas will be further narrowed. However, while maintaining optimism, we should also have psychological preparation and coping strategies for two situations. First, the COVID-19 epidemic has not been eliminated, especially the global spread is still continuing; Second, the long-term slowdown in economic growth has become a subject that must be faced after the new normal of the economy.

  Hold the bottom line and achieve the set goals

  In the next few years, the development policy of China’s agriculture and rural areas will still be to maintain stability and strive for progress. In 2022, the bottom line that agricultural and rural work must keep is to stabilize grain, increase oil and protect cultivated land, and there will be no large-scale return to poverty. In order to actively respond to the challenges faced in the development process and achieve the established goals, the following layout can be made in a targeted manner.

  First, strengthen the construction of high-standard farmland and continuously improve the level of improved agricultural varieties. It is necessary to fulfill the task of ensuring the supply of primary products proposed by the Central Economic Work Conference and ensure that Chinese’s rice bowl is firmly in its own hands at all times.

  First, we must accelerate the pace of high-standard farmland construction and stick to the bottom line of grain production. In recent years, remarkable achievements have been made in the construction of high-standard farmland in China. It is estimated that 1 billion mu of high-standard farmland will be built by 2022, so as to achieve a stable guarantee of grain production capacity of more than 1 trillion Jin. At the central level, the subsidy funds for farmland construction should gradually tilt to the main grain producing areas, and the grain production in various places should be taken as an important reference for the allocation of funds, so as to ensure stable and high yield in the main grain producing areas with high-standard farmland; In the process of implementation in various places, we can flexibly adopt a variety of subsidies and incentives to guide the investment of financial, social capital and new agricultural business entities, and at the same time establish and improve the participation mechanism of farmers to mobilize their enthusiasm for farmland construction and protection.

  Second, we must constantly improve the level of improved agricultural varieties. By the beginning of 2021, China has 520,000 germplasm resources, making it the second largest country in the world. At present, the planting area of self-bred varieties accounts for more than 95%, and the two major grain crops, rice and wheat, are completely self-sufficient, so that China has achieved China varieties for grain, and the safety of agricultural varieties in China is generally guaranteed. On the one hand, we should continue to promote the cooperation among scientific research institutions, seed enterprises and agricultural management entities, and accelerate the cultivation and marketing of improved varieties. On the other hand, we should continue to increase support for seed production counties and regional seed breeding bases, support local governments to create modern agricultural industrial parks focusing on seed industry, improve the modernization level of the industrial chain of the base, and increase seed production capacity.

  The third is to guide the increase of soybean and oil crops. It is necessary to guide and encourage farmers to increase production of soybeans and oil crops in light of the current domestic demand for agricultural products. In the main producing areas of soybean and oil crops, subsidies are given to agricultural production links and credit insurance and other services are provided in combination with local financial conditions.

  Second, develop and expand the new rural collective economy to increase farmers’ income. As an important support for rural modernization and common prosperity, the new rural collective economy helps to attract young and middle-aged laborers to return, improve the property income of rural residents, and then narrow the income gap and promote the development of rural industries.

  First, we should base ourselves on our own advantages and revitalize idle resources. Villages in all regions should make full use of local superior resources, adopt independent management, leasing, shareholding, etc., take advantage of location, and develop cultural services, management services, logistics economy and other services to revitalize idle construction land, homesteads, farmhouses and old office buildings. At the same time, take agricultural industrialization as the core and promote the development of characteristic industries. Promote the integration of rural primary, secondary and tertiary industries, let farmers participate more in the development of industrial chains, and leave more value-added benefits to farmers. The second is to let grassroots party organizations be "leading geese". To fulfill the requirements of the main tasks of the Party’s rural work in the new era, we should give full play to the role of grass-roots party branches. Mobilize the masses, develop rural industries, and effectively link the interests of village collectives and farmers by leading and running cooperatives.

  Third, continue to expand the main body of new agricultural management and promote the organic connection between small farmers and modern agricultural development. In 2021, the number of family farms and farmers’ cooperatives reached 3.9 million and 2.2 million respectively. In the future, we should continue to support the cultivation of new agricultural business entities such as family farms and farmers’ professional cooperatives, improve the financial and monetary policy system, provide financial and tax support, technical guidance and risk control for the development and growth of new agricultural business entities, and make them play an exemplary role in stabilizing production and ensuring supply. Through policy incentives, a number of productive service organizations covering the agricultural industrial chain, with high degree of specialization and standardized behavior will be formed to promote the standardized cultivation of agricultural products in China and achieve the development goals of reducing agricultural costs, increasing production and improving quality.

  We should speed up the construction of a productive socialized service system for small farmers. At present, there are 955,000 socialized agricultural production service organizations in China, covering an area of 1.67 billion mu, driving more than 78 million small farmers. Agricultural productive socialization service is an important way to realize the scale of modern agricultural technology and equipment operation under the background of a large number of small farmers, which is suitable for the subjective and objective requirements of small farmers’ integration into modern agricultural development at present, and more effective policy measures should be taken to promote their healthy development.

  Fourth, speed up the optimization of trade structure to ensure the supply of major agricultural products with double circulation. We should make full use of domestic and international markets and resources, actively promote the coordinated development of domestic demand and external demand, import and export, and effectively use the international market to meet domestic food demand. In the past 10 years, China’s grain imports have generally shown an upward trend, and the grain imports have more than doubled. China’s rising grain output has not reduced its dependence on grain imports.

  During the "Fourteenth Five-Year Plan" period, it is necessary to actively promote the diversification of China’s grain import sources and expand import channels. First, we must strengthen in-depth cooperation with countries along the Belt and Road Initiative; Second, we should actively broaden the overseas agricultural industrial chain, increase cooperation with relevant overseas grain enterprises, provide agricultural production services for local growers, especially investment in warehousing and logistics, and realize the control of the whole industrial chain. Especially with the entry into force of RCEP, the threshold of cross-border agricultural investment cooperation has been significantly reduced, and it is necessary to actively carry out regional agricultural industrial chain value chain cooperation.

  However, we need to be alert that the epidemic situation in COVID-19 continues on a global scale, and we should effectively deal with its possible negative impact on grain trade, especially to avoid the excessive dependence of major imported agricultural products on a single country and prevent the grain supply chain from breaking.

  Fifth, promote agricultural insurance and improve the market regulation and reserve system. In recent years, the market of agricultural products has fluctuated greatly, which has affected the healthy development of agricultural industry. It is necessary to vigorously promote agricultural insurance, establish a complete risk dispersion system, improve the market regulation and reserve system, and enhance the anti-risk ability of producers and operators of important agricultural products. First, we should improve the agricultural reinsurance system to effectively balance the regional risk differences. Use agricultural reinsurance business to eliminate the fluctuation of direct insurance business, and steadily promote subsidies for high-risk business of direct insurance business, so that insurance companies can focus on service capacity building and continuously improve the level of agricultural insurance protection. The second is to promote agricultural catastrophe insurance. On the one hand, it is necessary to expand the pilot scope of agricultural catastrophe insurance and cover major crops and important agricultural production activities as much as possible. On the other hand, it is necessary to establish a multi-channel agricultural insurance catastrophe risk fund, combine reinsurance to innovate financial instruments, and use diversified risk diversification tools to securitize agricultural catastrophe risks.

  Promote the reform and improvement of the grain reserve system. In addition to natural risks, agricultural producers and operators have to deal with market risks. In recent years, the price fluctuation of major grain crops has intensified, and it is necessary to further strengthen the macro-control ability of the market. First, we should promote the reform and improvement of China’s grain reserve system in a timely manner and establish a special grain reserve for market regulation in line with the central grain reserve. Second, it is necessary to reform the existing grain purchasing and storage mechanism, and change the temporary "skimming surplus" purchasing and storage to the domestic and foreign markets.

  Sixth, improve the logistics conditions in rural areas and promote the circulation of agricultural products and the consumption of rural residents. In order to promote the circulation of agricultural products and boost the consumption of rural residents, it is imperative to further improve the logistics conditions in rural areas in addition to ensuring the continuous growth of rural residents’ income. Logistics conditions belong to "hardware facilities", so it is necessary to speed up the improvement of the three-level logistics system in counties and villages and smooth the two-way circulation between urban and rural areas. By means of "express delivery into the village", farmers can efficiently connect with the market, which not only allows the means of production and consumer goods to enter, but also allows agricultural products to come out and realize the smooth flow of things.

  Seventh, continue to consolidate the achievements of tackling poverty and prevent large-scale return to poverty. Promote the promotion of characteristic industries in poverty-stricken areas, and continue to tilt financial funds to poverty-stricken areas to support the development of local industries; Use microfinance, agricultural insurance and other means to support poverty-stricken households to develop industries; Promote the stable employment and income increase of the people out of poverty, increase on-the-job training, and actively carry out labor cooperation.

Although the official has not announced the sales proportion of Sylphy Classic, it is certain that the more cost-effective Sylphy Classic model must have made great contributions. Now a new generation of Sylphy is about to go on the market, and Sylphy currently on sale has officially become a new Sylphy classic. In fact, this form of old and new generations selling together exists in many brands, and the sales volume proves that this method is very easy to use.

  CCTV News (Reporter He Chuan Kong Hua) The Yangtze River flows through the territory of Anhui Province, which is called Wanjiang River. The 800-mile Wanjiang River once gave birth to famous Huizhou merchants at home and abroad. Today, in the Yangtze River Economic Belt, Huizhou merchants are still shining.

  On July 1st, an interview group of reporters dancing in the Yangtze River Economic Belt walked into Hefei, the capital of Anhui Province. CCTV reporter learned from Hefei Export Processing Zone that one-eighth of the world’s computer sales come from here.

  In Lianbao (Hefei) Industrial Base in Hefei Export Processing Zone, the uniform factory buildings are endless, laptops are filed out at the end of the production line, and thousands of busy front-line industrial workers gather into a landscape.

  According to the person in charge of relevant departments of Lianbao (Hefei) Base, Lenovo Group and Taiwan Province Compal Group jointly set up this production base in Hefei Export Processing Zone, which was officially put into production on December 27th, 2012. By 2016, Lianbao (Hefei) Base has become the world’s largest PC manufacturer and Lenovo’s largest production base with an annual output of 30 million units.

  The person in charge said: "Lianbao (Hefei) base is the largest industrial enterprise in Hefei and the largest import and export enterprise in Anhui. Products are sold to 5 regions, 13 sub-regions and 126 countries around the world. For every 8 computers sold in the world, one is made by Hefei Lianbao. "

  Lianbao (Hefei) base is growing day by day, attracting upstream and downstream supporting enterprises like a magnetic field.

  It is understood that in Hefei Export Processing Zone, an electronic information industry cluster led by Lianbao has quietly formed. With the help of the marriage with Lianbao, Hefei Export Processing Zone quickly became the first phalanx of export processing zones in China.

  "In 2016, Hefei Export Processing Zone achieved an industrial output value of 43.04 billion yuan above designated size, a total import and export value of 3.62 billion US dollars, and paid various taxes of about 1.7 billion yuan. Among them, the total import and export accounted for 8.1% and 19.2% of the total import and export of the province and the city respectively, ranking sixth in the national export processing zone and second in the central and western regions for three consecutive years, writing a miracle of the development of inland export processing zones.

Five details to enhance the sense of fashion, half of women can do it without showing soil.

Modern women seem to have higher and higher requirements for their own image. With the general awakening of aesthetic consciousness, dressing well can only be said to be normal. Under this premise, fashionable people who are at the forefront of aesthetics are still pursuing outstanding dressing. Among all the qualities, advanced aura and fashion sense are the extra points that every woman is eager for.

This is not because women are naturally melodramatic, giving up leisure and laziness, just to deliberately pick and dress. On the contrary, women who have a sense of fashion are precisely those smart women who are clear-headed and know how to add points to themselves with external factors.

Fast-paced life polishes people’s patience, and even the most interesting soul wants to collide, it must start from the first impression. An image with a sense of fashion, in the external language, is almost equivalent to a sophisticated life and a discerning taste, so it is easier to make people feel good.

There are many sources of fashion sense, and you don’t need exaggerated clothes to do it. What I want to share with you in this issue is the specific details of avoiding rusticity and rusticity in daily life. In fact, every detail is not difficult to do, and women who seriously implement it can benefit from it more or less. Five details to enhance the sense of fashion, half of women can do it without showing soil, let’s take a look ~

Women who don’t love beauty and are not self-motivated will not take the initiative to read this article, so we can rule out the rule that they look rustic because they don’t dress up. The "rustic" problem that everyone usually encounters is probably caused by "overdressed".

Although the results of search engines are not accurate, they can also reflect more general results, and when I use search engines to search for the term "rustic", guess which star I found? I’m sorry, it’s Xuan Yi.

Before, she had a hot search because of her rustic style, and even some netizens commented that she always wore big names out of the feeling of selling goods on the ground.

To be fair, Xuan Yi’s appearance is definitely not rustic, and her small facial features are very delicate. However, her private service style always makes people want to vomit, because of her.The element is too full, let a person can’t find the line of sight, so dazzling.

Without the choice of collocation ideas, all the elements that can become bright spots will become fuzzy background boards, which can not play a positive role in decorating the trend elements.

It is possible that Xuan Yi chose this style because of her sweet and lively style, but the female stars with this style are not only her, like Nana Ou-yang, but also belong to the delicate and charming girl type, but Nana Ou-yang’s style appears more as a positive demonstration.

Nana Ou-yang, who is also a cool fashion brand, doesn’t have the feeling of being covered with elements. First of all, she knows how to use dark colors to suppress the agitation of large-scale printing. Secondly, there are only one or two highlights in her styling, so there will be no feeling of being too noisy.

Since we want to avoid the delicate rustic feeling, it is natural for some people to think, why not just wear a little plain clothes? There is no problem with the overall direction, but it is not enough to be simple and clean.

If the outline of clothing is messy, no matter how well it is done in other places and how expensive it is, it will still give people a rough feeling of untidiness.

suchThe messy feeling is not caused by overlapping.. We can see that many fashion bloggers clearly wear a lot of single items, but they still feel very capable and refreshing. This is because their clothing contours are well maintained, and there are no obvious wrinkles and indentations. In addition, the color system is unified, and it is easy to create an overall harmonious atmosphere.

Solid color items help to keep the contour clean.But too many decorative elements will also break this sense of conciseness. For example, some girls like to wear the palace style very much, and they are used to adding elements such as mesh, lace and doll collar when wearing coats, which not only makes the elements look noisy, but also destroys the cleanliness of the outline, so the upper body effect naturally does not have the ideal gorgeous texture.

In wearing, accessories may be the best detail to start changing. Sometimes we can meet some women who look very delicate in the street, but after careful study, we will find that their clothes are nothing unique, all basic models, and the only difference may be that their accessories are very attentive, so they look more fashionable than the people around them.

Miki, a very popular blogger, is proficient in accessories and likes to use hats and bags to enhance the atmosphere of dressing.

A simpler approach is actually to add a textured watch. Because compared with other accessories, wristwatches can not only serve as the focus, but also imply internal qualities such as punctuality, efficiency and stress on life, which can invisibly enhance a person’s temperament.

The content shared in front is all about dressing, and for human beings who look at faces, facial details can’t be ignored, and the distance between eyebrows and eyes is the key.

Why is the eyebrow eye important? This is a summary of life experience. You can recall whether most people who may have rustic problems around them have the problem of too narrow eyebrow-eye distance.

There are also many ready-made examples in the stars. Look at Zhao Liying with a steamed stuffed bun face and star eyes. In the comparison of her two styles, whoever is rustic and fashionable can be identified immediately.

The credit for erasing the rustic feeling mainly lies in the eyebrow shape. In fact, the outline of her eyebrows has not changed much, but the key lies in the change of thickness and the distance between the eyebrows and eyes, which makes her facial features more delicate at the same time.

Of course, if the eyebrow-eye distance is too wide or too narrow, it is easy to lower the face value. However, in real life, there are more people who look rustic because the eyebrow-eye distance is too narrow than those who look dull because the eyebrow-eye distance is too wide, so it is more noteworthy.

And those senior faces you see, such as NiNi and Liu Wen, have a wide eyebrow-eye distance, which can reflect a stretched state, and the calm aura created can also help to enhance the sense of fashion.

This last point has always been easily overlooked, but it is no less important than the previous four items:Stretching tall and straight posture is closely related to a person’s sense of fashion..

About posture training, we may hear more about raising our heads, holding our chests out and sinking our shoulders, so as to make ourselves tall and straight. However, this kind of training is carried out in private, not in front of people.

This view may run counter to common sense, but it is not difficult to understand if you think about it carefully. Because if there is no muscle memory after long-term training, this posturing is easy to make people look stiff.

Yang Mi, the queen of fashion, had this problem in her early days. Every inch of her skin seems to be exerting strength, but it gives people a very tight feeling, not to mention the fashion atmosphere.

The influence of posture on fashion sense should be understood from the spiritual core of fashion.Fashion is an attitude rather than a trend..

Whether you admit it or not, the fact is that those who are more confident and stretched will look more fashionable even if they wear the same clothes as others. And if the body is tight, even if it is full of trendy brands and high standards, it is still inevitable to be said to be rustic. Zhao Liying suffered a lot because he was nervous.

There are also positive cases, such as the carpet-fixing needle of the red carpet, Elaine Zhong. Looking at the photos of her 13-year attendance at the event, the dress at that time may not be fashionable enough today, but this does not prevent us from feeling that she is full of gas and is not inferior to her now.

Her aura comes from the right sense of relaxation in every part. For example, her waist often has a certain inclination, which makes her body show an S-shape, and her arms are also stretched out, and she rarely makes unconfident movements such as inserting her waist.

If you are convinced that your dressing style is appropriate and appropriate, then as long as you show your confidence loosely, many people will be impressed by your manners.

Ok, five details about improving fashion sense in this issue are shared here, and fashionistas can check how many they have done. See you next time ~Eli
