　　Xinhuanet reporter Zhang Wei

　　On the eve of the Spring Festival, General Secretary of the Supreme Leader made an investigation in Tianjin and visited the grassroots cadres and masses. This is the third time that General Secretary of the Supreme Leader has visited Tianjin for investigation and research since the 18th National Congress of the Communist Party of China.

Exploring domestic large aircraft： from Yun -10 to C919, realize the blue sky dream step by step.

　　On May 5, 2017, people with big plane dreams came to a small slope outside the fourth runway of Shanghai Pudong International Airport early, waiting for the exciting moment. On this day, it was the first flight day of C919, a large jet passenger plane independently developed by China, and the small earth slope outside the runway was affectionately called "Wangjiupo".

　　With the roar of the engine, the first C919 large passenger plane, piloted by captain Cai Jun and co-pilot Wu Xin, took off from the fourth runway of Pudong International Airport at 14: 00, rushed into the sky, and landed successfully 79 minutes later. After nine years of scientific research, numerous tests and technical debugging, there is once again the shadow of domestic large aircraft in the blue sky, which indicates that China has entered the ranks of a few countries with the ability to develop large passenger aircraft.

　　Now, more than two years have passed. What’s the progress of airworthiness certification of C919 passenger plane? When can Chinese get on a large domestic plane? Recently, the reporter came to China Commercial Aircraft Co., Ltd. for a field visit.

　　Yun -10: Leaving an innovative gene is an attempt to commercialize domestic aircraft.

　　Arriving at the Pudong base of China Comac Shanghai Aircraft Manufacturing Co., Ltd., I saw a large plane with a white fuselage and several blue and white stripes sleeping peacefully on the lawn of the industrial park, with a bright red flag on its tail. This unique large passenger plane in the world soared in the blue sky of China more than 30 years ago, and its name was Yun -10.

　　Boarding the Yun -10 plane, the reporter was shocked by the industrial level at that time. The throttle lever, pedals, various instrument panels and indicator lights in the cockpit are reasonably arranged and fully functional. In addition to the seats for the main driver, the co-pilot and the pilot, there is also a seat for the mechanic. When the aircraft breaks down in flight, the mechanic can go down to the inside of the aircraft from the passage next to the seat for maintenance. When you come to the cockpit, the passenger seat is no different from the common big plane now, except that the distance between the front and back of the seat is larger, the ride experience is more comfortable, and there is an ashtray on the armrest.

　　In August 1970, with the approval of Comrade Zhou Enlai, the state agreed that the report on trial production of transport aircraft in Shanghai should be centralized by the Ministry of Aviation Industry. The mission name is "Project 708" and the aircraft code is "Yun -10". According to statistics, at that time, more than 300 factories, research institutes and universities in 21 provinces, autonomous regions and municipalities participated in the development of Yun -10 aircraft.

　　On September 26th, 1980, Yun -10 successfully made its first flight in Shanghai. Subsequently, Yun 10 flew all over the country, reaching 10 cities, including Beijing, Harbin, Urumqi, Guangzhou, Kunming, Chengdu, Hefei and Zhengzhou. The longest time for a single flight was 4 hours and 39 minutes, and it completed a scientific test flight that flew over 3,600 kilometers in 3 hours and 42 minutes. Its performance and use characteristics fully met the design requirements. Yun -10 also flew over the Himalayas to Tibet seven times, transporting more than 40 tons of urgently needed materials for Xizang Autonomous Region.

　　Although the Yun -10 aircraft project was not officially put into commercial use for various reasons, the Yun-10 spirit of "independence, strong cooperation, selfless dedication and continuous innovation" has been passed down from generation to generation by large aircraft people.

　　Next to the lawn where Yun -10 plane docked, there stands a sculpture engraved with the four characters "Never give up", which is a solemn promise from the heart of the big plane people and the earnest expectation of hundreds of millions of people for the early commercialization of domestic big planes.

　　Time has entered the new century. In February 2000, the state decided to support the production of domestic civil aircraft and accelerate the development of regional air transport. In June, 2002, the State Development Planning Commission issued a document officially approving the establishment of the new regional aircraft project. The result is a new turbofan regional plane that has soared in the blue sky of China today — — Arj21 (advanced regional jet for 21st century) means advanced jet regional aircraft in the 21st century. ARJ21-700 is its basic model, and it is the first time that China has developed and produced regional aircraft in strict accordance with the internationally accepted regulations on aviation airworthiness management.

　　ARJ21: Delivered the 21st aircraft, accumulating valuable experience for the civil aircraft industry.

　　Not long ago, on November 29th, Comac China delivered the 21st ARJ21-700 aircraft to its customers. Talking about the differences between civil airliners and other aircraft, Ye Chao, deputy director of ARJ21 Division of China Comac Shanghai Aircraft Manufacturing Co., Ltd., has a lot to say: "The independent development of a jet regional aircraft needs to go through the processes of design, trial production, test flight, evidence collection, production, etc. This is not all. To make the aircraft truly commercialized, it must be tested by the market. If the requirements of airlines cannot be met, the cost performance ratio is low, and the experience of drivers, flight attendants and passengers is poor, the mission of the aircraft will not be truly completed. "

　　In the process of design and development, the ARJ21-700 aircraft has fully considered the number of seats, comfort and the needs of the aviation market in western China. Compared with similar aircraft, the cabin of ARJ21-700 aircraft has a higher and wider cabin, the cabin height is more than 2 meters, reaching the same cabin comfort as that of narrow-body aircraft, and the cabin height is close to 1 meter, which can provide more luggage space for passengers. The economy of the aircraft is also more prominent, and the engine fuel consumption is low. In order to adapt to the complex geographical environment in the west of China, the ARJ21-700 aircraft pays attention to take-off and climb performance in design, and can take off and land in a short distance, which has a strong advantage in the adaptability of western routes and western airports.

　　Although customers’ needs were fully considered in the design and manufacture, when facing the customer representatives seriously, Comac found that there were many details to be perfected. Because, from "product" to "commodity", the difference is not just one word, but also thousands of times of self-improvement and continuous collision with customers.

　　In Ye Chao’s view, there were three "self-revolutions" on the sales road of ARJ21-700. "When we sold the plane to Chengdu Airlines for the first time, it was the first time that we delivered the plane to our customers. During the continuous running-in, we found that some problems that we had never thought of were exactly the concerns of our customers. The second time ‘ Self-revolution ’ When the plane was delivered to Tianjiao Airlines. We have changed from serving one customer to serving two customers, which requires us to be more refined in technology and operation specifications. Now we are facing the third time ‘ Self-revolution ’ New customers such as Air China, China Eastern Airlines and China Southern Airlines will put forward more new requirements for our products. In the future, we should look at production from the perspective of creating handicrafts. "

　　Since the commercial operation of the ARJ21-700 in June 2016, the optimization and improvement of the aircraft production process has been carried out almost every day. "For example, the pilot’s operation has been greatly modified to reduce the pilot’s workload; In order to reduce the noise in the engine room, the conventional sound insulation cotton material is replaced by metal damping layer and rubber sound insulation material; In order to reduce the airflow noise at the air outlet of the air conditioner, silencers are installed, and there are various optimizations for flight attendants and aircraft maintenance personnel. " Ye Chao said.

　　With more and more orders, the mass production capacity of ARJ21 has gradually improved. In 2017, it will produce 4 aircraft, in 2018, 11 aircraft, and strive to produce more than 20 aircraft in 2019. Behind the digital beat is the continuous improvement of the overall efficiency of the workstation and the efficiency of skilled workers. Comac China has continuously promoted the innovation of production management in terms of process technology, on-site management, production operation control and so on. From January to September this year, the batch production rate of ARJ21 aircraft increased by 76.9% compared with the same period in 2018.

　　The development of ARJ21 regional jet has accumulated valuable experience for the development of China civil aircraft industry. After the whole process of jet regional aircraft design, trial production, test flight, evidence collection, production, delivery and operation, China has the development capability and airworthiness certification capability of jet regional aircraft, and people have more confidence in the future of large passenger aircraft projects.

　　C919: All tests are carried out in parallel, and the test will be prepared for "evidence collection".

　　In the avionics system comprehensive laboratory of Comac Shanghai Aircraft Design and Research Institute, researchers are busy, and the indicator lights are flashing on the rows of computers. On the monitors one by one, the program codes pass by in turn, and the C919 aircraft is being tested and verified here.

　　Walking into the iron bird test-bed of C919 aircraft, the test-bed in front of us looks like an "iron bird", except that it can’t fly, and its shape and internal structure are basically the same as the real C919 aircraft, so it can be called a simulation aircraft. The integration tests of flight control, landing gear, hydraulic system, etc. are all completed here. After the command is issued from the console, Iron Bird completes the relevant specified actions, confirms and verifies that the system design meets the requirements of product development, and ensures flight safety. The international mainstream aircraft manufacturers have completed the technical verification and technical improvement of related models through the Iron Bird test bed. "In addition, it has another function: when the flight test of the C919 aircraft fails, we can simulate it through the iron bird test bed and find a solution to the failure." Li Tao, director of the construction of the State Key Laboratory of Civil Aircraft Simulation Flight of Shanghai Aircraft Design and Research Institute, said, "At present, we are intensively carrying out the airworthiness verification test of the laboratory."

　　Isn’t the C919 plane already empty? What are the researchers still busy with?

　　"We are working on the airworthiness certification of the C919 passenger plane, that is, ‘ Textual research ’ . At present, laboratory tests are being carried out here, in addition to on-board ground tests, flight tests, simulator tests and supplier product identification tests. After the success of the R&D test flight of the C919 passenger plane in 2017, it still needs several stages of test flight and airworthiness evidence collection before it can be delivered to the airlines. " Li Tao said.

　　In order to ensure the efficient ground test and flight test on board, "in October this year, 105 aircraft completed the first test flight, and the number of aircraft used for flight test will reach 6 in the future, and related flight test work is being carried out in parallel." Nan Guopeng, captain of 105 aircraft of C919, introduced.

　　Simulator tests are also being carried out in an orderly manner in Shanghai Aircraft Design and Research Institute. Boarding the C919 passenger aircraft engineering simulator, this equipment looks like a big ball, and its interior is almost the same as the real aircraft cab. Li Tao introduced: "The simulator can undertake the test tasks such as aircraft control law evaluation, cockpit evaluation and safety evaluation. At the same time, it can also undertake the training and training of test flight crews to help pilots understand aircraft performance as soon as possible. "

　　It is understood that before the C919 large aircraft is delivered for use, it is necessary to obtain three certificates, namely: type certificate (TC), indicating that the aircraft design is safe and seaworthy; Production license (PC), which indicates that the aircraft manufacturing system meets the requirements and can be produced on a large scale; Single Airworthiness Certificate (AC) proves that a single aircraft is in a safe and available state, which is equivalent to the "driving license" of a car. These work plans will take two to three years to complete. If they go well, Chinese will be able to take a large domestic plane designed and manufactured by himself in the near future.

　　In addition to the joy and pride of flying in a large domestic plane, the development of C919 has a long-term strategic significance. It is not a simple product, nor is it an ordinary commodity. The manufacture of large passenger aircraft is known as the "crown of modern industry", which plays a very significant role in driving the civil aviation industry and modern industry.

　　From the perspective of aviation industry, with Shanghai as the leader, more than 200 enterprises and nearly 200,000 people from 22 provinces and cities including Shaanxi, Sichuan, Jiangxi, Liaoning and Jiangsu participated in the development and production of large passenger aircraft projects. The China civil aviation industrial chain, value chain and innovation chain driven by the C919 large passenger aircraft have great energy, and at the same time, it has promoted the establishment of 16 joint ventures in airborne systems such as avionics, flight control, power supply, fuel and landing gear, which has promoted the civil aircraft industry in China.

　　From the perspective of upgrading the modern industrial level, a commercial aircraft consists of 3 million to 5 million parts. These parts need to be produced by thousands of suppliers, which can promote the group breakthrough of key technologies in the fields of new materials, modern manufacturing, advanced power, electronic information, automatic control, computer and many other basic disciplines. "There are many domestic suppliers involved in the parts of the C919 passenger plane, and the fuel tanks, valves and landing gear equipment of the hydraulic system are all produced in China. Through the C919 project, we have grown together with our suppliers. " Li Tao said.

　　At dusk, when leaving Shanghai Aircraft Design and Research Institute, the research building was still brightly lit. In order for the C919 to be delivered as soon as possible and soar in the sky, another night for technicians began … …

　　Interview notes

　　It takes only 4 hours and 18 minutes to get from Beijing to Shanghai by high-speed train, but it is not necessarily faster than the high-speed train, not counting the waiting time for the flight to take off and queue up. However, this reporter still chose to fly because he had a question in his heart — — When can we get on the big plane made by Chinese himself?

　　Not long ago, I was chatting with a friend. When he heard that all the large passenger planes we are taking now are foreign products, his face showed a very surprised look: "What? However, our fighter plane, the National Day military parade is so beautiful, and manned space flight has already sent astronauts out of the earth. How can we buy a foreign plane? " The reporter told him: "It won’t take long. I will definitely bring you back the latest progress when I go to Comac for an interview this time. "

　　The plane rushed into the sky and entered the stratosphere. The reporter took out the "Safety Tips" from the front seat pocket and saw that the plane on flight CA1855 was Boeing 787. Thinking of a news I just saw recently, the order for C919 large aircraft has exceeded 1,000. Maybe a few years later, the reporter will watch Safety Tips again, and the models on it will be different.

　　With countless questions, I came to Pudong base of Shanghai Aircraft Manufacturing Co., Ltd. and Shanghai Aircraft Design and Research Institute. The reporter finally knew why civil aircraft manufacturing was so difficult. What is carried on it is not goods, nor one or two people, but dozens and hundreds of lives, and there is no room for any safety problems. In addition, the performance requirements of civil aviation aircraft are also very high. During the service period, an aircraft generally has to go through 60,000 flight cycles (take-off and landing) and 90,000 flight hours, with a service life of 30 years or more. Even some seemingly unremarkable parts on the plane must be used stably and safely for decades. In order to compete with the world aviation market, the large aircraft we build must be safer, more comfortable, more environmentally friendly and more economical than others, so as to have a broad market.

　　The big plane people are working hard for all this.

　　In an interview, the reporter really felt their busyness and dedication. The interview was interrupted several times by phone calls, and the interviewee repeatedly pressed the phone for fear of influencing reporters to ask questions. When a reporter asked a researcher at Shanghai Academy of Aeronautics and Astronautics, "Are there any touching stories in your work?" He smiled and said, "It’s nothing. Everyone usually completes the test task seriously." The colleague sitting on the side couldn’t help it. She grabbed the conversation and said to the reporter, "Our researchers are really selfless. Many technical backbones are in their thirties and forties, old and young. In order to complete the airworthiness forensics work as soon as possible, they basically work overtime every day. You will know when it gets dark." Hearing this, the former researcher who said there was no story was somewhat silent. He said, "Last Friday, I got home after 10 o’clock in the evening and found that my wife didn’t let the children sleep. When I thought about it, I went out early and returned late. The child has not talked to me for a week. " These little details permeate all aspects of the interview, which is moving.

　　When leaving the interview, the reporter remembered the 16 Chinese characters hanging on the wall of the C919 assembly workshop — — Long-term struggle, long-term research, long-term hardship and long-term dedication, after the delivery of more than 20 ARJ21, the C919 will also be delivered in the next two or three years, and the CR929 wide-body passenger aircraft jointly operated by China and Russia will also start construction in the next few years.

　　Let’s look forward to it. In the blue sky, there are more and more domestic passenger planes.

Does COVID-19 vaccine contain aluminum adjuvant to damage brain？ That’s outrageous!

　　With the increasing number of people vaccinated in COVID-19, the rumors that vaccines are harmful to health are constantly changing. No, there are rumors that aluminum adjuvant nanoparticles in COVID-19 vaccine can cross the blood-brain barrier and damage the brain. A string of terms seems to be "professional", but in fact it is purely alarmist. The latest issue of the "Science" gossip list is released, which focuses on refuting several recent widespread health pseudo-knowledge. Come and see if you are successful.

　　The monthly "scientific" gossip list is guided by Beijing Science and Technology Association, Beijing Municipal Committee Network Information Office, Capital Internet Association, and jointly released by Beijing Science and Technology Journalists Editors Association and Beijing regional website joint rumor platform.

　　Rumor has it that the aluminum adjuvant contained in COVID-19 vaccine hurts the brain

　　Truth There are rumors that COVID-19 vaccine can’t be used, because aluminum adjuvant nanoparticles (AAN) in the vaccine can’t be digested by macrophage (MF) enzyme, and will be transmitted to the brain through the blood-brain barrier (BBB) to cause damage and affect human health. Is it true?/You don’t say.

　　Professional terms such as "nanoparticles" and "MF digestive enzyme" with English abbreviations at first glance seem to be scientific interpretations issued by professional institutions. However, some of the most basic concepts are wildly wrong.

　　First of all, the diameter of aluminum hydroxide (or aluminum phosphate) particles used in vaccines is generally 1-10μ M is far from the level of "nanoparticles", so there is no such risk in itself. Secondly, it is impossible for aluminum hydroxide to cross the blood-brain barrier, because the upper limit of molecular diameter allowed by the pore size of the blood-brain barrier is usually only 1nm(1μ M=1000nm), aluminum hydroxide particles don’t say in the past, stuck.

　　In addition, after vaccination, because the adjuvant plays the role of adsorbing antigens, only a very small amount will enter the blood circulation, but that aluminum is far below the concentration that may cause risks, even worse than the daily intake from vegetables and fruits.

　　Aluminum adjuvant has been used for decades, and scientists have been paying close attention to the "theoretical" risks, but so far it has not been found that aluminum adjuvant can cause substantial damage to people (even newborn babies), so just vaccinate with peace of mind.

　　It is rumored that the human body will "lose temperature" in extremely cold environment.

　　Truth Some people think that only in extremely cold environment can the human body lose its temperature. Actually, not really. The core temperature of the human body is fixed. The surface temperature can fluctuate sometimes, but the core temperature will be kept as stable as possible from 37℃ to 37.5℃. When it is hot, it dissipates heat, and when it is cold, it generates heat to keep the heat.

　　Compared with sweating, the heat generation and maintenance are passive and the adjustment is limited, so passive clothing and shelter from the outside are very needed to help them resist the low temperature. This is also the reason why human beings gradually expanded from tropical to cold zone in the process of evolution. Only when they have certain heat preservation ability can they live in cold regions.

　　When we lack the protection of clothing and shelter and accidentally appear in a cold environment, we can’t maintain the core temperature, and temperature loss may occur, even in a very cold environment. Generally speaking, the lower the outside temperature, the stronger the wind and the higher the environmental humidity, the easier it is to lose temperature. Temperature loss is not very serious at the beginning, and the human body will stubbornly fight against this hypothermia through compensation mechanism, so after exposure to low temperature environment, it will gradually lose temperature from light to heavy.

　　It is very important to find and identify temperature loss in time and take measures quickly. The treatment of rewarming should follow the principle of gradual and gentle grading, and unprofessional rescue may aggravate the harm to the body. For example, don’t try to heat the limbs or drink hot water for people with moderate or severe hypothermia. The hypotension and further temperature drop caused by a large amount of hypothermic blood returning to circulation will increase the risk of resuscitation failure.

　　It is rumored that hanging fitness can treat cervical spondylosis.

　　In some areas, there are fitness people who treat cervical spondylosis by hanging their heads and swinging with the rope. "Hanging neck fitness" exercise is similar to "cervical traction" in clinic. Middle-aged and elderly people who are keen on "hanging neck fitness" think that it is good for cervical spine to let the neck be pulled, but the answer is no.

　　Like this improper "neck-hanging fitness", the traction force is far greater than the need of clinical treatment, which may damage nerve tissue, muscles, tendons and ligaments, and even cause paraplegia and life-threatening if the condition gets worse.

　　To do traction therapy, we need to follow two principles, namely, symptomatic principle and moderate principle. Clinically, there are two kinds of cervical spondylosis suitable for traction: one is chronic neck and shoulder pain, which can relax tense muscles and effectively relieve pain symptoms through moderate traction. Secondly, cervical spondylotic radiculopathy, which is often manifested as radiation pain or numbness of upper limbs, heavy feeling and decreased grip strength, can be treated with appropriate traction, but it is definitely not advisable to exercise with excessive intensity and too long time, like the above-mentioned "neck hanging" exercise.

　　In addition, it should be noted that traction treatment is prohibited for patients clinically diagnosed as "cervical spondylotic myelopathy, cervical spondylosis with vertigo symptoms and unstable cervical spondylosis" because high-intensity "neck-hanging" traction may destroy the already unstable intervertebral disc nucleus structure, further compress the nerves, aggravate the symptoms of pain and numbness, and may even cause adverse consequences such as paralysis and death.

　　Therefore, before traction treatment, you must go to a regular hospital to improve the relevant examination, and after being evaluated by a professional doctor, traction treatment should be carried out under the guidance of a doctor.

　　It is rumored that shaking and waking up in sleep is a signal of "sudden death"

　　Truth Have you ever had such an experience? When you were about to fall asleep in a daze, your whole body suddenly shook violently. There are rumors that this is a signal of "sudden death", indicating that there is a big problem in the body. In fact, this phenomenon is called "sleep shock", also known as "sleep twitch" or "myoclonus before sleep"

　　The brain is the general commander of various organs and tissues of the human body, and sleep is the process of brain rest. When people just fall asleep, part of their brains are already asleep, but some of them are still not completely asleep. With the deepening of sleep, the brain relaxes its control over the limbs. When the brain is stimulated by some information inside and outside the body, local muscles of the body may suddenly twitch, which is called sleep shock.

　　If we understand the causes of sleep startle, we will know that it is incorrect to say that the sudden whole body shaking during sleep is caused by the brain’s "strike" to remind us that our lives are in danger, and this is not a signal of "sudden death". It is reported that about 60% to 70% people have had this kind of personal experience.

　　It should be noted that sleep startle is mostly a physiological manifestation, which is often accidental, not more than three times a night, and the movement range is not too great. If limb twitches occur frequently (more than five times a night) or sleep is disturbed by frequent attacks and repeated awakenings, you need to be vigilant. It is necessary to go to the neurology department or sleep specialist clinic to improve polysomnography.

　　This examination is helpful to distinguish between sleep fright and other causes of limb movement during sleep. At the same time, other examinations such as blood examination and imaging examination can also be improved to determine whether there are other causes.

　　It is rumored that eating less staple food can cure diabetes.

　　Can the truth really cure diabetes by giving up starchy food, eating less fruits with high fructose content, not drinking drinks and refusing to process food? There are many ways to treat diabetes. In most cases, the improvement of the disease is the result of a variety of methods, such as diet, exercise, drugs, etc., which cannot be used as an excuse to exaggerate the efficacy of a particular method.

　　At the end of the 18th century, Dr. John Rollo in Britain took the lead in noticing the therapeutic value of low-carbon water diet for diabetes. The "low-carbohydrate diet, high-fat and high-protein diet mode" advocated by him has far-reaching influence, which makes people realize the adverse effects of high-carbon water diet on diabetes, but it is also the ideological source of many dietary misunderstandings at present, such as "diabetics can’t eat fruits" and "it doesn’t matter if they eat vegetables casually".

　　If the staple food is excessively restricted, and carbohydrates are not eaten for a long time or rarely, fat will have to provide excessive calories, which will adversely affect the metabolism of brain and myocardium, which is mainly powered by glucose. At the same time, excessive intake of high fat and high protein will aggravate the metabolic load of liver and kidney, and the incidence of cardiovascular and cerebrovascular complications may also increase.

　　The scientific diabetes diet model is not absolute and single, but should aim at everyone’s different tastes, preferences, etc. Under the guidance of professionals, choose a personalized diet that suits them, and continue to enjoy their favorite foods to the maximum extent in a healthy way, instead of blindly pursuing a certain dietary "special effect".

　　Gossip mosquito repellent paste has better protection effect.

　　Truth Compared with other traditional mosquito-repellent products, mosquito-repellent stickers can provide "personal protection". Is the effect really better? Not necessarily. Some plant-derived mosquito repellent drugs such as citronella and eucalyptus citriodora leaf oil are put in new products such as mosquito repellent stickers and mosquito repellent bracelets. The principle is to achieve mosquito repellent effect through odor emission, but its range of action is relatively small, which cannot provide full-body protection and is not as effective as local mosquito repellent.

　　In 2018, Beijing Consumers Association conducted a comparative test on pure plant mosquito repellent products, involving 50 kinds of domestic and partially imported mosquito repellent products such as mosquito repellent stickers, mosquito repellent bracelets and mosquito repellent buckles. Results The mosquito repellent effect of all 50 samples was not satisfactory, which was suspected of false propaganda.

　　These products are mainly sold to special groups such as children and pregnant women, but there is no uniform production standard. Although most of them claim to be plant formulas, there is no clear scientific evaluation of the safety of these formulas at this stage, and some countries do not recommend the use of such plant formula mosquito repellent products for infants and young children at present. For example, lemon eucalyptus oil may cause lung discomfort and allergic reactions, and the US Centers for Disease Control and Prevention recommends that children under 3 years old should not use it; Canada does not recommend it for infants under 12 months.

　　In a word, compared with other mosquito repellents, these new mosquito repellent products have the advantages of short use time and no scientific experimental research. Therefore, the safety has not been verified, and it is not recommended for younger children.

Du Shanxue, the ＂wise man＂： Ask the ＂master＂ for the driving route.

Du Shanxue inspected the public security forces in 2008. 　

　　　　 On June 19, the website of the Supervision Department of the Central Commission for Discipline Inspection announced the news of the fall of two provincial and ministerial officials in Shanxi almost at the same time.

　　　　　　　　Surprisingly, Du Shanxue, the former member of the Standing Committee of Shanxi Provincial Committee and vice governor, was robbed of all the limelight by the then vice chairman of Shanxi Provincial Political Consultative Conference, and almost no one paid attention to this native Shanxi leader.

　　　　　　　　Du Shanxue, 58, is from Linyi County, Yuncheng City, Shanxi Province. He has been an official for more than 30 years, and at every stage, he has been promoted step by step by grasping the policy direction and keeping the pulse of the times, and gradually got the evaluation of "smart people".

　　　　　　　　In the process of promotion, he used "article road" to clear the way, "image card" as a foothold, and "Zhouyi Gua" as an escort, and then acted step by step.

　　　　　　　　Until the fall of the horse, Du Shanxue was still diligent in writing political articles and making intensive public appearances. It was noticed that the tail end of his unique broom eyebrow had turned white.

　　　　　　　　After the fall of the horse, many people familiar with him reflected on his ups and downs. Du Shanxue calculated the beginning and process, but he didn’t guess his own result.

Win favor with an article

　　　　　　　　Du Shanxue’s official career began with an article.

　　　　　　　　In the late 1970s and early 1980s, at the beginning of reform and opening up, all walks of life in China were in urgent need of talents. In the spring of 1982, Du Shanxue, who graduated from the Accounting Department of Shanxi University of Finance and Economics, joined the Shanxi Provincial Finance and Trade Committee as the first batch of graduates after resuming the college entrance examination.

　　　　　　　　"’Xiao Du’ is very clever and has a good business." A colleague of Du Shanxue recalled that the young man from Yuncheng wore a pair of glasses, and he was always smiling and good at talking. He read books and newspapers when he had nothing to do.

　　　　　　　　Du Shanxue, then 26, was also trying to show his "good business".

　　　　　　　　In September, 1982, the Twelfth National Congress of the Communist Party of China was held, which put forward the financial concept of "a game of chess in the whole country", and suggested that the proportion of central and local fiscal revenues and the proportion of corporate profits should be appropriately adjusted according to the actual situation of industries in different regions. Based on the situation in Shanxi Province, Du Shanxue wrote the article "Discussion on Management of Extra-budgetary Funds" and published it in the first journal of Shanxi University of Finance and Economics in 1983.

　　　　　　　　Three months after the article was published, Du Shanxue was transferred to the third office of the General Office of Shanxi Provincial People’s Government. A veteran cadre who has been immersed in Shanxi officialdom for many years recalled that at that time, young people who could write and do things were very popular. Du Shanxue, who worked in the provincial government, is still popular because of his "agility".

　　　　　　　　Since then, the habit of "writing articles" has run through Du Shanxue’s entire political career.

　　　　　　　　According to the statistics of public information, Du Shanxue served as the deputy director of Shanxi Provincial Department of Finance for 10 years, and published more than 10 articles in 7 periodicals such as Shanxi Finance and Economics, Finance and Market, and led a team to study the topic of "Enlightenment of Shanxi Banks on Modern Financial Risk Prevention".

　　　　　　　　Since then, Du Shanxue has published three works in five years in Changzhi municipal government, seven works in three years in Changzhi city, three works in one year in Lvliang Municipal Committee, and six works in three years after becoming a member of the Standing Committee of Shanxi Provincial Committee.

　　　　　　　　"His articles always follow the political trend." A Shanxi official who knows him well said that from the 12th National Congress to the 18th National Congress, it has been a compulsory course for Du Shanxue to find the "wind direction" from policies and documents for more than 30 years.

　　　　　　　　Du Shanxue’s "topical articles on current politics" will lead the implementation time of specific policies from time to time, and most of his administrative methods are in line with the political mainstream.

　　　　　　　　In 2000, when financial departments all over the country took the implementation of government procurement system as a way to deepen the reform of fiscal expenditure management, Du Shanxue’s article "Government Procurement and Building a Clean Government" had been published for more than a year.

　　　　　　　　After "Scientific Outlook on Development" was put forward, Du Shanxue also promoted "green development" in Changzhi, trying to make Changzhi a rare city with fine features in Shanxi, a big coal province.

Smell the wind to plant trees.

　　　　　　　　According to a person familiar with Shanxi officialdom, Shanxi is a big province with coal resources, and there are few cities with "fine features". We have worked hard on the image of the city and achieved quick results in political achievements.

　　　　　　　　After Du Shanxue was in charge of Changzhi, he gradually explored this "road of political achievements". This has also become the focus of his administration during his administration of Changzhi and Lvliang.

　　　　　　　　In February 2003, Du Shanxue came to Changzhi, served as deputy secretary of the municipal party committee, and became mayor of Changzhi a month later.

　　　　　　　　At the beginning of 2003, Changzhi just sent away Lv Rizhou, a former party secretary with personal heroism. During Lv Rizhou’s three years in Changzhi, he created a unique way of governance, such as the Changzhi Daily criticized officials by name, the government did not set up a fence, and rode to the countryside. For a time, Changzhi and Lv Rizhou became an inseparable whole.

　　　　　　　　Du Shanxue, who first arrived in Changzhi, was looking for a breakthrough for himself in the post-Lv Rizhou era.

　　　　　　　　Yang Lin (not his real name), an official of Changzhi City, said that in Shanxi, Changzhi did not have the advantage of playing the economic card and eating energy meals, and Du Shanxue also made such an attempt.

　　　　　　　　Yang Lin said that Du Shanxue didn’t smoke or drink at that time, and he was preoccupied with political achievements. After the Third Plenary Session of the 16th CPC Central Committee, "Scientific Outlook on Development" came into public view. Therefore, in October 2004, Du Shanxue’s book Promoting the All-round Development of Government Work with Scientific Outlook on Development was published.

　　　　　　　　Yang Lin said that at that time, Du Shanxue only grasped the key policy points and put forward the slogan of "Green Changzhi", which was after 2005.

　　　　　　　　In 2005, Du Shanxue’s article "Harmony and Development of Building a Charming City with Strength" was published. In the article, based on the national strategic background of "the rise of central China" and the development direction of "circular economy", he proposed to inject "circular economy" into industrial development, and made predictions for the development of Changzhi according to the plans of Bohai Economic Belt, Longhai Economic Belt and the Central Plains Economic Development Circle that was not yet formed at that time.

　　　　　　　　Du Shanxue’s political sense of smell was praised again. Since then, the slogan of "Green Changzhi" has made Changzhi begin to attract attention.

　　　　　　　　"Look at so many trees in Changzhi, all of which were transplanted by Lao Du at that time." Yang Lin said that in 2006, the Changzhi Municipal Party Committee and Municipal Government issued the document "Building a First-class Forestry Ecological City in the Province". By the end of 2008, "100,000 Trees" began to enter the city vigorously.

　　　　　　　　Shanxi Evening News once reported that Changzhi invested 50 million yuan to transplant 100,000 trees into the urban area. The main tree species were Sophora japonica, willow and fatong, and their DBH was above 10 cm.

　　　　　　　　Many Changzhi citizens recalled that there were suddenly many trees in Changzhi, which made it inconvenient for them to drive. For example, because there were many trees, it was inconvenient for cars to enter and exit. Finally, these trees that occupied the place were removed.

　　　　　　　　Du Shanxue wrote a special article in 2010 to summarize the Changzhi greening project represented by "trees entering the city".

　　　　　　　　In the article, he wrote that since 2006, the Changzhi Municipal Party Committee and Municipal Government has raised 1.87 billion yuan for greening, mainly from government investment and environmental restoration and governance deposits of coal enterprises. Among them, the financial investment at the city and county levels is 1.66 billion yuan.

　　　　　　　　These investments have brought Changzhi the titles of national garden city and national forest city.

Based on "image card"

　　　　　　　　Du Shanxue, who was encouraged by the "image card", continued to maintain and expand this style, just as he got the opportunity from "making a fuss".

　　　　　　　　In June 2008, the whole country was preparing for the Olympic security, and Changzhi was no exception.

　　　　　　　　On the morning of June 5th of that year, Du Shanxue, then secretary of Changzhi Municipal Party Committee, stood on an open-top military vehicle with his feet, and slowly passed by the main road in front of Bayi Square in Changzhi City, inspecting the police and armed police teams standing on the side of the street. In his own way, he recorded the "Changzhi-style Olympic security drill".

　　　　　　　　Deng Xin (not his real name), a politician from Changzhi, who is close to Du Shanxue, said that on June 5, 2008, in order to match the national Olympic spirit, Changzhi held an Olympic security swearing-in meeting. The leaders of the municipal party committee and the municipal public security system conducted a comprehensive review of the police, fire fighting and armed police teams in Changzhi, and each team also performed their skills in anti-terrorism, riot prevention, fire fighting and traffic command.

　　　　 Now, on the website of Changzhi municipal government, you can also find graphic records about this "swearing-in meeting". In the published picture, the military vehicle where Du Shanxue stood was labeled as "Reading Police Car". After the vehicle where he was standing, Bo Li, then director of Changzhi Public Security Bureau, stood in the reading police car and accompanied him with a military salute.

　　　　　　　　Later, Deng Xin looked up the information about the Olympic security drills conducted all over the country on the eve of the 2008 Olympic Games. At that time, the "Olympic security drills" held in Chongqing, Jinan, Shenyang and other places were all conducted in a relatively closed space, such as anti-terrorism and security drills. Unlike Changzhi City, the city leaders were not allowed to inspect dozens of square teams.

　　　　　　　　"Lao Du has a good face and likes to use’ form’ to express his work." Deng Xin said that Changzhi and Lvliang’s "Sweeping the City Movement" can best reflect his characteristics.

　　　　　　　　In order to enhance the image of the city, the doorways of street shops in Changzhi City should be changed into "white boxes with red (blue, yellow) background and white characters", and government units should divide regional contracting tasks and be responsible for the doorways replacement of merchants in their respective regions. Merchants only need to pay the money to the responsible person designated by the government, and the price ranges from 4000 to 7000 yuan.

　　　　　　　　Merchants specializing in this kind of billboards in Changzhi said that the billboards that the government requested to be replaced have a frame and a bottom, which belongs to the high cost of advertising doorplates. It would be more economical to find a doorplate vendor for this kind of billboards. The merchant said that the merchant who changed the house number at that time was not local to Changzhi.

　　　　　　　　Changzhi City, which pays attention to image, was rated as "National Civilized City" in 2011. It was also in this year that Du Shanxue was transferred to the post of Secretary of the Municipal Party Committee of Lvliang.

　　　　　　　　"My previous leaders of the municipal party committee have developed the economy very well, so my job is to improve the living environment for the people of Lvliang." This is what Du Shanxue said to the media when Lvliang took office.

　　　　　　　　Finding his feeling from the "image card", he launched a massive "three rectification" campaign in Lvliang, namely, environmental sanitation, street decoration and traffic order.

　　　　　　　　"Being neat and beautiful is the requirement of’ Lao Du’." A citizen of Lvliang said that at that time, doors were being torn down, plaques were being changed and walls were being painted everywhere in Lvliang Avenue.

　　　　　　　　This citizen has witnessed the discoloration of a wall several times: at first, it was painted white, then it turned gray, then it was pink, then it was ugly and changed to white, and finally it was painted gray.

　　　　　　　　An insider close to the Lvliang Municipal Government said that the "three rectifications" also emphasized accountability and publicity.

　　　　　　　　At that time, the main leaders of the urban areas and counties in Lvliang signed a written pledge to fulfill a military order, and all units took the lead in the environmental remediation activities in the contracted areas. Due to the ineffective actions of the "three remediation", Lvliang City also punished many county-level cadres, and Du Shanxue was called the "sweeping iron hand" secretary locally.

　　　　　　　　In July, 2011, Lvliang also held a live observation meeting on "Three Remedies" in Shanxi Province, inviting the media to visit.

　　　　　　　　According to a media person who participated in the report at that time, Du Shanxue attached great importance to the media propaganda of "three rectifications" in Lvliang. When having dinner with reporters, he specially got up and toasted one by one, encouraging reporters to "write Lvliang skillfully".

　　　　　　　　However, in view of the "three rectifications" activities in Lvliang, some people in the legal profession have publicly questioned in the "Democracy and Legal Times" that in the process of "three rectifications", the rule of man is greater than the rule of law, which is inconsistent with the Administrative Law and the Property Law. Therefore, the legal profession believes that Du Shanxue is too eager for quick success and instant benefit.

An uncertain ending

　　　　　　　　Ten months later, Du Shanxue, who "swept" a city, became a member of the Standing Committee of Shanxi Provincial Committee in the midst of controversy, and three months later, Du Shanxue became the Secretary General of Shanxi Provincial Committee.

　　　　　　　　Du Shanxue, who walked through the "article road" and played the "image card", finally ushered in the peak of his career.

　　　　　　　　During this period, a person who once worked with Du Shanxue said that Du Shanxue, a member of the Standing Committee of the Provincial Party Committee and Secretary-General, was not as good-tempered as he used to be in Changzhi and Lvliang, and often openly criticized his subordinates, leaving many jobs in a passive situation. "He was restless every day and believed in Zhouyi."

　　　　　　　　The Paper learned that Du Shanxue was interested in Zhouyi as early as during his administration of Changzhi. According to an insider, Du Shanxue pays special attention to "how to walk" besides paying attention to the placement of tables and chairs and the orientation of flowers and plants.

　　　　　　　　The insider said that Du Shanxue believed in a "master" from Henan, and he would ask the master to help him figure out the driving route. Sometimes he felt unlucky on the conventional walking route, so he would take a divination or ask the "master" which way to take.

　　　　　　　　A Changzhi official who had followed Du Shanxue to the countryside for investigation revealed to The Paper that Du Shanxue sometimes changed its route and it was very puzzling.

　　　　　　　　At 6 o’clock in the morning of November 14th, 2005, on the Fen (Yang)-Tun (Liu) Highway in Guodao Town, Qinyuan County, Changzhi City, many teachers and students of a class in Qinyuan No.2 Middle School were crushed to death by a large truck that came at a gallop during morning exercise.

　　　　　　　　At that time, Du Shanxue, the mayor of Changzhi, went to inspect the situation. "They started from Changzhi at 8: 00 a.m. and drove to the scene of the accident for one hour at most, but the motorcade led by Du Shanxue made a detour and went to a nearby village for investigation, and arrived at the scene of the accident near 11: 00 noon."

　　　　　　　　The Changzhi official recalled, "At that time, everyone thought that it was estimated that the mayor was afraid that the scene was too miserable to watch."

　　　　　　　　"Du Shanxue has always been cautious. Over the years, he has indeed formed his own politics." Another person close to the Shanxi provincial government said that with the extension of his official term, Du Shanxue could no longer find a sense of security by "analyzing policies" in his early years, and he had to rely on the culture and experience he believed in.

　　　　　　　　The culture that Du Shanxue believes in is Zhouyi, and the accumulated experience over the years is "making achievements and showing more".

　　　　　　　　Du Shanxue, who returned to work as a member of the Standing Committee of Shanxi Provincial Party Committee, still kept writing. In less than two years, he wrote six articles, covering issues such as "maintaining the purity of the party" and "doing a good job in letters and visits".

　　　　　　　　In February 2014, under the background of "practical education of the Party’s mass line", Du Shanxue published the article "Make good use of the bottom line thinking" to discuss how to serve the people pragmatically and honestly.

　　　　　　　　Thirty-one years ago in the spring, Du Shanxue was transferred to the general office of the provincial government three months after he published the article "Discussion on Budget Funds Outside Management".

　　　　　　　　Thirty-one years later, it was still spring. As a member of the Standing Committee of Shanxi Provincial Party Committee and deputy governor, three months after he published this article "Make Good Use of Bottom Line Thinking", the Central Commission for Discipline Inspection announced the news of his fall.

　　　　　　　　This time, he has been working hard in the officialdom for more than 30 years, and his sense of smell is still sensitive, but his accuracy is reduced.

　　　　　　　　The above-mentioned people close to the Shanxi provincial government said that at one time, when Du Shanxue met people outside the officialdom, he strictly demanded one-on-one, and some people noticed in public reports that his broom-shaped eyebrows began to turn white.

　　　　　　　　After Du Shanxue was taken away, some retired veteran cadres who were familiar with him said, "This smart man, after 30 years, is not bad in the front and middle, but he has no pulse of’ anti-corruption’."

Diversified ＂ice and snow+＂mode helps cultural tourism to warm up ＂cold＂ resources and ＂hot＂

CCTV News:2023— The competition of Chongli Station of the 2024 International Snow Federation freestyle skiing and snowboarding U-track World Cup kicked off yesterday (December 6) in Genting Ski Park, Chongli District, Zhangjiakou City, Hebei Province, which is also one of the highest-level ice and snow events held in China after the Beijing Winter Olympics.

After the Beijing Winter Olympics, this Winter Olympics Road has once again taken on a new look. Competition organization, event guarantee, etc. followed the Zhangjiakou operation team during the Beijing Winter Olympics, and more than 100 top skiers from all over the world, including three Winter Olympics champions, gathered together. All the players and officials are very excited to be able to hold this high-level competition in a brand-new venue.

According to the competition plan, the qualifying competition will be held from 6th to 7th, and the final competition will be held from 8th to 9th. China freestyle skiing and snowboarding national training team sent 25 players to participate in this home game, including Winter Olympics champion Gu Ailing, four-time Winter Olympics veterans Liu Jiayu and Cai Xuetong. While striving for good results, we should temper the team’s skills and competitive strength with the goal of Milan Winter Olympics.

Large-scale events continue to drain ice and snow, and the heat of sports continues to rise.

At the Beijing Winter Olympics, freestyle skiing and snowboarding won three heavy gold medals for the China team. However, with the related events gradually entering the public’s field of vision, people’s enthusiasm for participating in ice and snow sports has been continuously pushed up. The freestyle skiing and snowboarding U-track World Cup attracted skiers from all over the country to watch the competition.

In the Genting Ski Park in Zhangjiakou, the U-shaped venue for the World Cup is adjacent to the Volkswagen Snow Road. Even the people who didn’t buy tickets to watch the race can stop on the snowy road to watch the wonderful performances of the athletes, many of whom came from other places to watch the race.

According to Genting Ski Park, the organizer of the event, the booking volume of the ski resort increased by nearly 200% this weekend, and most of the tickets and hotel rooms have been sold out. At the same time, superimposed with cultural and recreational activities such as electronic syllables of snow-capped mountains held on weekends, it is expected that the passenger flow will rise sharply this weekend.

In December, Beijing and Zhangjiakou held many international high-level events with the help of the Winter Olympics venues. This weekend, in addition to Genting World Cup, Shougang Short Track Speed Skating World Cup and National Gymnasium Figure Skating Grand Prix Finals will be staged at the same time. Driven by the top ice and snow events, Beijing’s winter Olympic legacy and extensive ice and snow sports are constantly giving new vitality.

Revitalize the winter Olympic heritage and promote the in-depth development of ice and snow sports

The Beijing Winter Olympics ignited everyone’s enthusiasm for participating in ice and snow sports, and also left a rich Olympic legacy. After the Beijing Winter Olympics, Beijing and Zhangjiakou vigorously promoted the spirit of Beijing Winter Olympics, made good use of Beijing Winter Olympics heritage, and promoted the in-depth development of ice and snow sports.

During Genting World Cup, the "One Card Sliding" of Zhangjiakou Ski Resort in Beijing was officially unveiled. For the first time, the "Beijing-Zhangtong Skating Card" has realized cross-regional skiing in China. With a snow ticket, skiers can skate in 11 large ski resorts in Beijing and Zhangping, such as Wanlong, Genting, Taiwu, Huaibei and National Alpine Ski Center.

Winter Olympic venues and facilities are high-quality resources for the post-Olympic economy. Taking the Winter Olympics as an opportunity to achieve high-quality development, it is necessary to make the Winter Olympic venues and facilities "busy". In Beijing, the National Speed Skating Pavilion "Ice Ribbon" has received more than 500,000 visitors since it was officially opened to the public in July 2022, realizing a seamless switch from "the fastest ice" to "the public’s ice".

In Zhangjiakou, the just-concluded "National Youth Four Seasons Ski Challenge" attracted nearly 300 young athletes from all over the country. It is worth mentioning that this event, sponsored by Beijing Ski Association, has been carried out by using Zhangjiakou’s rich ice and snow resources all the year round, and has become a new model of complementary resource advantages and coordinated regional development between Beijing and Zhangjiakou.

It is understood that nearly 20 international events were held this year with the help of Beijing Winter Olympics venues or facilities. At the same time, in late December this year, the State Sports General Administration will also launch the 10th National Popular Ice and Snow Season. This year’s national mass ice and snow season will make good use of the Beijing Winter Olympics heritage, implement the "Ice and Snow Benefiting the People Plan" and the "Ice and Snow Plus" strategy, build an ice and snow economic system, promote the transformation of the ice and snow sports industry, and effectively promote the "event economy" and the high-quality development of the ice and snow sports industry.

Create a clear cyberspace and build a good network ecology

　　On December 20, 2019, the National Internet Information Office issued the No.5 Regulation on Ecological Governance of Network Information Content (hereinafter referred to as the Regulation), which will take effect on March 1, 2020. This is an important legislation in the management of network information content in China, which systematically responds to the problems faced by the current network information content service market, and comprehensively stipulates the management requirements that the network information content producers, network information content service platforms, network information content service users and network industry organizations should abide by. The "Regulations" provide important guidance for promoting the healthy and orderly development of online information content, and provide a strong guarantee for protecting the legitimate rights and interests of citizens, legal persons and other organizations and safeguarding national security and public interests.

　　First, the needs of the times to promote the modernization of the national governance system and governance capacity

　　The Third Plenary Session of the 18th CPC Central Committee put forward the major proposition of "promoting the modernization of national governance system and governance capacity" for the first time, and set "perfecting and developing Socialism with Chinese characteristics system and promoting the modernization of national governance system and governance capacity" as the overall goal of comprehensively deepening reform. The Fourth Plenary Session of the 19th CPC Central Committee adopted "the Central Committee of the Communist Party of China’s Decision on Several Major Issues Concerning Upholding and Perfecting the Socialism with Chinese characteristics System and Promoting the Modernization of the National Governance System and Governance Capacity", which pointed out the direction for upholding and perfecting the Socialism with Chinese characteristics system and promoting the modernization of the national governance system and governance capacity.

　　Only by implementing the spirit of the Fourth Plenary Session of the 19th CPC Central Committee and building a good network information content ecology under the background of accelerating the modernization of the national governance system and governance capacity can we grasp the fundamental direction of promoting the modernization of the national governance system and governance capacity. The development of network technology has broken through the time and space limitation of information dissemination, expanded the scope of information dissemination, innovated the means of information dissemination, and triggered a fundamental change in the pattern of information dissemination. Cyberspace has become a new channel for people to obtain information, learn and communicate, and a new carrier of cultural communication. Cyberspace is completely changing people’s production and life style and profoundly affecting the historical development process of human society. Therefore, the governance of network information content ecology plays an increasingly prominent role in promoting the modernization of national governance system and governance capacity. It is necessary to build a good network order according to law and protect the orderly and free flow of cyberspace information according to law. To create a good network ecology, we should follow Socialism with Chinese characteristics’s core value system and core values, vigorously cultivate and carry forward the socialist core value system and core values, and accelerate the construction of a value system that fully reflects China’s characteristics, national characteristics and characteristics of the times.

　　Second, the objective need to create a good network ecology

　　In recent years, with the rapid development of the Internet, many network information service providers have enjoyed the technology dividend, which has realized the rapid development of enterprises. The technical ability and service level of network information service providers have been greatly improved, and the types and types of services have been increasing. Correspondingly, the traditional platform management responsibilities are still insufficient, and the mismatch between responsibilities and capabilities is prominent.

　　With the advent of the information explosion era, netizens have an increasingly urgent need for serious information and objective reports. Many network information service providers strictly abide by professional ethics, adapt to the characteristics of the network era, and deliver a large number of quality and in-depth network information. However, some network information service providers intend to get the maximum push volume and the highest click rate, which makes illegal and bad information flood the user interface and seriously affects the ecological order of network information content. Some spread politically harmful information, maliciously tamper with the history of the party and the country, vilify heroes and discredit the image of the country; Some create rumors, spread false information, and act as a "title party" to profit from rumors and attract attention from fakes, disrupting normal social order; Some wantonly spread vulgar pornographic information, violate public order and good customs, challenge the moral bottom line, and damage the healthy growth of young people; Some use a large number of self-media accounts in their hands to maliciously market, engage in "black public relations", extort money, infringe on the legitimate rights and interests of normal enterprises or individuals, and challenge the legal bottom line; Some arbitrarily plagiarize infringement, wantonly wash manuscripts and powder, build false traffic, and undermine the normal communication order. If these chaos can’t be effectively cured, it can’t meet the people’s reasonable demand for serious information and objective reports, and it will also affect the dignity of laws and regulations, damage the interests of the broad masses of the people, and destroy the good network ecology.

　　General Secretary of the Supreme Leader pointed out that the cyberspace is clear and the ecology is good, which is in the interests of the people. Cyberspace is smoky and ecological deterioration, which is not in the interests of the people. Standardizing and managing illegal information on the platform according to law and preventing and resisting the spread of bad information are social and legal responsibilities that network information service providers must bear.

　　Three, the overall network information content management legal system needs to be ruled by law

　　At the first meeting of the Central Leading Group for Cybersecurity and Informatization, General Secretary of the Supreme Leader pointed out that it is necessary to promptly formulate legislative plans, improve laws and regulations such as Internet information content management and key information infrastructure protection, govern cyberspace according to law, and safeguard citizens’ legitimate rights and interests.

　　Since 2016, in order to cope with the new features and challenges of network information services, based on the Network Security Law and the Measures for the Administration of Internet Information Services, China’s network information content management system has been continuously enriched and improved, and gradually formed Internet news, user account names, Internet search services, mobile Internet applications, Internet live broadcasts, Internet forum communities, Internet groups, Internet users’ public accounts, microblogs, blockchains, and online audio and video. These regulations have basically determined the management requirements of real-name registration system, personnel management, daily inspection, emergency response, rumor dispelling mechanism, reporting complaints and so on. In the past, through publicity and implementation, special actions and centralized law enforcement, various management measures have been deeply rooted in the hearts of the people and have been recognized and supported by the majority of netizens. Network information service providers actively implement various system requirements, standardize their own service behavior, and improve service quality according to laws and regulations.

　　The promulgation of the "Regulations" is a summary and sublimation of the past management experience, reaffirming the established management systems from the height of ecological governance, centralizing and coordinating the various systems of network information content management in the form of departmental regulations, and further implementing the requirements of legalization of network information content management. The "Regulations" have important phased significance for standardizing and leading all kinds of network information service providers to spread positive energy and carry forward the main theme, while curbing and preventing illegal information and bad information. The "Regulations" make government supervision, industry self-discipline and social autonomy all run on the basic track of rule of law, provide a basis and standard for measuring, standardizing and guiding interpersonal behavior and relationships in cyberspace, and can promote the healthy and orderly development of cyberspace.

　　Core tips

　　The report of the 19th National Congress of the Communist Party of China put forward: implementing the strategy of rural revitalization. By paying attention to the construction of modern agricultural industrial system, production system and management system, we can realize the organic connection between small farmers and modern agricultural development, thus vigorously promoting agricultural modernization production.

　　The "three systems" of modern agricultural industrial system, production system and management system are the key tasks and grasping hands of modern agricultural construction in China in the new period. How will our city effectively promote the construction of "three systems"? Around this theme, relevant municipal units and grassroots cadres expressed their views.

　　Comprehensively promote the construction of the three major systems

　　"The three systems put forward in the report of the 19th National Congress of the Communist Party of China have pointed out the direction for how to realize modern agriculture." Huang Junyi, director of the Economic Management Department of the Municipal Agriculture Committee, said that how to promote modern agriculture is the key to building a modern agricultural industrial system, production system and management system.

　　Huang Junyi said that agriculture is the foundation of building a well-off society in an all-round way and realizing modernization, and it is a strategic industry. Realizing agricultural modernization is an important goal of China’s agricultural development. To realize agricultural modernization, we must closely focus on the construction of modern agricultural industrial system, production system and management system.

　　In the next step, in promoting the three major systems of modern agriculture, our city will align itself with the requirements of the central authorities, combine the spirit of the 19th Party Congress with the reality of Chongqing, do a good job in characteristic benefit agriculture, popularize advanced agricultural technology, build a new type of agricultural business entity, and work hard to realize the precise implementation of the spirit of the 19th Party Congress under the background of implementing the rural revitalization strategy.

　　Prosperous industries and rich farmers

　　"Industry is the carrier and support of agricultural development. Industry is prosperous, rural areas are prosperous, and farmers are rich." Hong Guowei, director of the Economic Work Department of the Municipal Agriculture Committee, said.

　　In the next step, on the basis of promoting modern agricultural industrial system, production system and management system, our city will actively develop regional brands by strengthening brand building and effectively enhance the added value of agricultural products; By encouraging scientific researchers to develop new varieties adapted to Chongqing’s local natural conditions and advanced agricultural technologies adapted to large-scale production and commercial production, the effective combination of production system and industrial system can be realized; Management system is the key to the construction of modern agricultural system, so it is necessary to further promote the construction of agricultural system and give the industrial system a strong impetus.

　　Let "thoroughbred+good law" enter thousands of households

　　"Improved varieties and good methods are the direct embodiment of agricultural science and technology content, which has a great role in promoting farmers’ income." Li Jie, secretary of the Municipal Agricultural Technology Station, said: "The report of the 19th National Congress of the Communist Party of China regards the production system as one of the three major systems for building modern agriculture, and puts forward higher requirements for agricultural technicians."

　　As the main department responsible for the technical popularization and technical service of planting industry in our city, the Municipal Agricultural Technology Station will further introduce new varieties of planting industry and cultivate varieties that meet the local natural conditions and market demand in Chongqing. Introduce and test new technologies, so that the technology of increasing production and increasing efficiency can adapt to Chongqing’s three-dimensional mountain conditions; Through the protection of basic farmland and the construction of cultivated land fertility, strengthen the monitoring of soil fertilizer and farmland water to ensure the clean environment of agricultural production; Strengthen the monitoring of fertilizer quality and residue, product identification and registration management, etc., to achieve safe production from farmland to table.

　　Actively develop new business entities

　　"The development of industry and the adoption of improved varieties and good laws ultimately need to be implemented in human practice, so what kind of new business entities are adopted is the key to promote the all-round development of the three systems." Huang Junyi said.

　　How to adapt the management system to the development of modern agriculture when the second round of land contract is extended for another 30 years? Huang Junyi said that the city will focus on building a modern management system, actively develop new business entities such as family farms and professional cooperative organizations, improve agricultural production efficiency through moderate scale operation, and at the same time let producers get more profits; Under the background of extending the contract period for another 30 years, by vigorously promoting socialized services, the production of rural single-family households will be brought into the system of socialized large-scale production, so that farmers’ production can effectively meet the market demand and adapt to modern agricultural production methods.

Children, it’s labor class! —— Focus on several concerns of the new edition of labor classes in primary and secondary schools.

　　Xinhua News Agency, Beijing, May 11thQuestion: children, have a labor class! — — Focus on several concerns of the new edition of labor class in primary and secondary schools

　　Xinhua News Agency "Xinhua Viewpoint" reporter

　　Primary and middle school students should learn to cook and stew soup, grow vegetables and raise birds, and repair household appliances … … The Ministry of Education recently issued "Compulsory Education Labor Curriculum Standards (2022 Edition)". From the fall semester of 2022, a variety of labor skills will be included in the curriculum, which has aroused great concern in society.

　　A survey by Xinhua Viewpoint reporter found that the society generally agrees that primary and secondary school students should learn labor skills, but there are different views on how to teach, how to evaluate and how to keep labor classes from becoming a mere formality.

　　The relevant person in charge of the Ministry of Education said that it is a major change in the new compulsory education curriculum plan to separate the class hours occupied by labor from the comprehensive practical activity curriculum. The content and form of the new labor course are more advanced with the times, rich and diverse.

　　What to study: cooking and cleaning, planting and breeding, public welfare work, etc.

　　In fact, many people are no strangers to labor classes. Picking up food after 1960s, sweeping the playground after 1970s, and doing manual work after 1980s and 1990s are unique memories of many students.

　　From studying engineering and agriculture to incorporating labor education into the teaching plan, and then making it clear that labor class is a compulsory course, although the form and name have changed, labor class has always existed in the curriculum system of primary and secondary schools in China.

　　It is understood that the new labor curriculum standard is aimed at education "emphasizing learning and neglecting labor" for some time; Emphasis on achievements and light hands-on. The relevant person in charge of the Ministry of Education said that this time, the labor class was separated from the original comprehensive practical activity class in order to better implement labor education. Through the important way of labor class, we can cultivate students’ correct labor values, good labor habits and quality, and make them become new people who understand, know and love labor.

　　According to the new curriculum standard, the course has ten task groups, which are divided into three categories: daily life labor, productive labor and service labor.

　　Among them, daily life labor includes four task groups: cleaning and sanitation, sorting and storage, cooking and nutrition, and use and maintenance of household appliances. Productive labor includes four task groups: agricultural productive labor, traditional craft production, industrial productive labor and new technology experience and application. Service labor includes modern service labor, public welfare labor and voluntary service.

　　Yao Yijie, deputy director of the Basic Education Research Office of Guangdong Education Research Institute, believes that this new curriculum standard is very comprehensive, covering not only all kinds of life scenes, but also labor practices such as agriculture, industry and service industry.

　　Chu Zhaohui, a researcher at the Chinese Academy of Educational Sciences, said that the labor class in the new curriculum standard combines skills, skills and scientific and technological practice activities, and the concept of labor is more complete.

　　The reporter looked up the labor curriculum standards and found that the curriculum arrangement is gradual. With the promotion of the study period, the difficulty of the project gradually increases and the skills are gradually improved. For example, the first and second grades should be able to choose and wash vegetables, the third and fourth grades should boil eggs and cook jiaozi, the fifth and sixth grades should fry eggs and stew soup, and the junior middle school should design three-meal recipes.

　　How to attend classes: the content is not uniform, and a diversified education platform and practice base are built.

　　"It can be satisfied to raise a goldfish at home. How to raise poultry buildings such as chickens and ducks?" "Who will teach? How to teach? Does the school have conditions and venues? " "It is a good thing for children to learn labor skills, but can it be done at school? Don’t take it home and let parents take care of it and shoot videos?" ……

　　After the release of the new curriculum standard, many parents left messages on social platforms, expressing their support for their children to learn and master labor skills, but they still have questions about how to attend the class.

　　Gu Jianjun, head of the labor curriculum standard group of compulsory education in the Ministry of Education, said that as a course, the school plays a leading role, the family plays a basic role, and the school, family and society work together to promote it.

　　Regarding the heated discussion on planting vegetables and raising poultry, Gu Jianjun said that the selection and determination of projects, curriculum resources and venue construction should be tailored to local conditions and not across the board. Conditional schools can build safe and reliable labor fields and places that meet the educational requirements, and at the same time make full use of all social forces to build diversified educational platforms and practice bases.

　　In fact, primary and secondary schools in many places have carried out the exploration of labor courses with their own characteristics.

　　Xinghu School, Liangjiang New District, Chongqing opened the roof of a teaching building of more than 6,000 square meters as a plantation, planted more than 10,000 sunflowers, and the students weeding, watering and harvesting by themselves. In rural primary and secondary schools in tan tang, Guigang, Guangxi, "schools have bases and classes have plots of land", and labor education counselors such as agricultural professionals and experts in planting and breeding are very popular among students.

　　On January 18th, 2022, students picked vegetables at the "Roof Farm" of Wangcheng School in Nan Zhou, Changsha. Xinhua News Agency reporter Chen Zeguo photo

　　"Labor class can’t simply preach, otherwise it will become a mere formality and become ‘ Swing ’ Labor education. " Cheng Dean, a member of the Chongqing Municipal Political Consultative Conference, said that schools in big cities and rural schools, schools in the south and schools in the north, have different natural environments and conditions, so they should adapt to local conditions, make the courses operable and provide students with real labor opportunities.

　　Who will attend the labor class? In particular, how to solve some course teachers who need professional skills? Many school teachers interviewed by the reporter are very concerned about this.

　　The Ministry of Education previously requested that colleges and universities should strengthen the training of labor education teachers, and qualified colleges and universities should offer labor education-related majors; Carry out labor education teacher training.

　　Xiong Bingqi, president of the 21st Century Institute of Education, suggested that all localities should ensure the investment in school labor education and strengthen the construction of full-time teachers in labor classes. Strengthen cooperation and linkage with vocational schools and social institutions, revitalize resources inside and outside the school, and hire outstanding craftsmen from different industries, inheritors of intangible cultural heritage, experienced farmers and skilled workers as instructors.

　　How to evaluate: the evaluation of labor literacy that is not included in the examination items is used as a reference for admission to a higher level school.

　　After the announcement of the new curriculum standard, many parents asked: "How to mark the labor class?" "Will there be an exam in the labor class?" "Will the labor class be linked to further studies?"

　　In 2020, the Central Committee of the Communist Party of China and the State Council issued "Opinions on Comprehensively Strengthening Labor Education in Colleges, Middle Schools and Primary Schools in the New Era", which proposed that the evaluation results of labor literacy should be regarded as an important content to measure students’ all-round development, as an important reference and graduation basis for appraising excellent students, and as an important reference or basis for admission to higher-level schools.

　　Chu Zhaohui said that the current curriculum standards and policy requirements did not include labor education in the senior high school entrance examination.

　　"As a process-based comprehensive quality evaluation, labor education focuses on examining the process and performance of students’ labor practice, and cannot be simply evaluated by exams like Chinese and mathematics." Fan Yongfeng, a professor in the Education Department of Southwest University, believes that attention should be paid to the acquisition and growth of each student, such as the improvement of labor skills and the formation of labor habits.

　　On November 10, 2021, students from Class 1, Grade 3 of Chengguan No.3 Primary School in Pingli County, Shaanxi Province learned to fold clothes in the school housekeeping room. Xinhua News Agency reporter Shao Ruishe

　　In Qiaoshaxu No.2 Primary School, Panyu District, Guangzhou, which has implemented labor education, the school adopts multiple evaluation methods consisting of students’ self-evaluation, mutual evaluation, teachers’ evaluation and parents’ evaluation to select "Top Ten Small Experts in Planting", "Labor Class Activists", "Small Farmland Activists" and "Small Experts in Household Work" on campus. Li Minning, the principal, said that multi-party participation in the joint evaluation not only recognized students’ labor achievements, but also promoted students’ labor enthusiasm.

　　"Labor education also needs the cooperation of parents." Gu Jianjun believes that parents need to change their concepts, attach importance to the value of labor and life skills for the growth of minors, and integrate labor into daily life. "For example, children learn to scramble eggs with tomatoes at school. After returning home, parents should give students the opportunity to practice as much as possible. In order for children to learn at school and go home to do it, parents need to let their children do what they can. "

　　"Can form a school teaching — — Practice at home — — The cycle of school evaluation really allows students to develop working habits. " Huang Lifang, principal of Guangzhou Wende Road Primary School, said. (Reporter Song Jia, Ke Gaoyang, Zheng Tianhong, Hu Hao)

Canada said that the discovery of China’s ＂spy network＂ was refuted by the Ministry of Foreign Affairs of China

　　　　On March 30th, Canadian researchers claimed to have discovered the "spy ghost network" in China, but the Chinese side refuted it. Qin Gang, spokesman of China’s Foreign Ministry, said on March 31st that some people abroad are always keen to fabricate rumors of so-called cyber espionage in China, which are totally groundless.

　　　　Qin Gang pointed out that there is a kind of "ghost" called "cold war" and a virus called "China threat theory" abroad, and people possessed by "cold war ghost" carry the virus of "China threat theory" and attack from time to time. These people’s attempts to discredit China through rumors will never succeed.

　　　　The Citizen Lab of moncton International Studies Center of the University of Toronto and SecDev Group in Ottawa released the report "China’s cyber spies invaded 1295 computers in 103 countries", and the response was low-key. When the reporter of Global Times tried to interview, Ronald, the spokesman of the report, said that he refused to be interviewed by the media, and stressed that the report they published did not accuse any organization, including the China government, of being responsible for this "ghost network". Ronald also said that "the presence of the server in China does not necessarily mean that it is related to the China government" and "I hope the outside world will read and understand the contents of the report carefully".

　　　　Despite China’s stated position and the low-key response of the researchers who submitted the report, some western scholars and media are still clamoring for "China’s espionage theory". On March 31st, CTV, a private Canadian television station, recalled the words of Canadian Public Security Minister Van Luoan, linking the China government with the "ghost spy network". When attending an international conference on cyber security in Washington, Fan Luoan called "network infiltration from abroad" the biggest hidden danger threatening Canadian national security, but did not mention China. However, some Canadian media and intelligence experts took the opportunity to involve China, linking this "ghost spy network" with China.

　　　　In France, a so-called "China intelligence expert" named Faligot claimed in an interview with AFP on March 30th that although there was no evidence in the Canadian report, his sources allowed him to judge that it was "obvious" that this cyber attack was related to "China agents", and "it can be said that there was irrefutable evidence". However, the "expert" did not submit what he called "hard evidence", but only repeated the words in the report. In 2008, this person published a book entitled "From Mao Age to Olympics: China’s Secret Activities".

German media said that the CIA or concocted a "ghost spy network" to plant China.

　　　　A few days ago, a report released by the University of Toronto claimed that there was a huge "ghost network" in China, and "China cyber spies invaded 1,295 computers in 103 countries in two years". All kinds of remarks have been heated by western media, which once again ignited the so-called "China Hacking Theory". In response to various rumors, many western experts said in an interview with the media that the China government’s participation in the "ghost network" was groundless, and some network experts also found that some anti-China organizations were behind the scenes. > > detailed
