　　When presiding over the sixth collective study in the Political Bureau of the Communist Party of China (CPC) Central Committee, General Secretary of the Supreme Leader emphasized that "we should pay attention to drawing theoretical innovation wisdom from the creation of the masses". If a society wants to be prosperous and full of vigor and vitality, it must constantly carry out theoretical innovation. People’s nature is the essential attribute of Marxism. The Party’s theory comes from the people, for the people and for the benefit of the people. The people’s creative practice is an inexhaustible source of theoretical innovation. The important exposition of the Supreme Leader General Secretary adheres to the Marxist historical materialism and the standpoint of people first, which clarifies the source of the party’s theoretical innovation and provides a fundamental follow-up for constantly writing a new chapter in the modernization of Marxism in China.

　　The people are the creators of history.

　　Marx and Engels systematically thought about the relationship between man and history, holding that the primary premise of human history is "the existence of living individuals", and pointed out that history is the history of living people in material form, not the history of spirit or will. Social existence determines social consciousness and mode of production determines social development, which is the basic viewpoint of Marxist historical materialism. Material production activities are the basic conditions of all history, and all social life is practical in essence. Marx clearly pointed out in the Manuscript of Economics and Philosophy in 1844 that history "is nothing more than a process in which people are born through human labor, and it is a process in which nature generates for people". Man creates history through his own practical activities, and social history is composed of his practical activities, and man is the real subject of social history.

　　The people are the creators of material wealth and spiritual wealth. Marxist historical materialism holds that people’s practical activities not only create an objective material world, but also create a rich spiritual world. The people are the creators of material wealth. Material production is the premise of all history. Without certain material production, there can be no human history. The material materials needed for human survival and development are produced by the broad masses of the people. As the main body of material production activities, the people constantly accumulate production experience in practice, innovate and create production technologies, and promote the development of productive forces and the growth of social material wealth. The people are also creators of spiritual wealth. Social existence determines social consciousness, which is a reflection of social existence. The production practice of the people provides a material basis for the creation of spiritual wealth, and all spiritual wealth is rooted in the practical activities of the people.

　　General Secretary of the Supreme Leader pointed out: "The people are the driving force to create history, and we communist party people should never forget this most basic truth of historical materialism." Productivity is the fundamental driving force for the development of human society. The contradictory movement between productivity and production relations promotes the continuous development of human society, and the people are the most active factors for the transformation of productivity. The people’s subjective practical activities constitute the foundation of social life, and all social changes are based on this foundation. While creating material wealth and spiritual wealth, the people also create and transform social relations of production. Any social change cannot be separated from the people’s active participation and the people’s enthusiasm and initiative. Marx and Engels pointed out that "historical activities are the activities of the masses, and with the deepening of historical activities, it will certainly expand the ranks of the masses." Although heroes also play an important role in historical development and change, social change ultimately depends on the will, wishes and interests of the broad masses of the people. From the perspective of historical materialism, only the people are the real creators of history and the fundamental driving force for social change and social reform and development.

　　2. People’s creative practice is an inexhaustible source of theoretical innovation.

　　Great times need great theories. The Central Committee of the Communist Party of China’s Resolution on the Great Achievements and Historical Experience of the Party’s Centennial Struggle takes "persisting in theoretical innovation" as one of the historical experiences of the Communist Party of China (CPC)’s Centennial Struggle, and points out: "As long as we are brave enough to combine new practices and constantly promote theoretical innovation and be good at guiding new practices with new theories, we will certainly be able to show Marxism a stronger and more convincing truth force on the land of China." The reason why our party can make great achievements in various historical periods lies in mastering Marxist scientific theory and constantly promoting theoretical innovation in combination with new realities. We should constantly deepen our understanding of the regularity of the party’s theoretical innovation and achieve more fruitful theoretical innovation results in the new era and new journey.

　　Marxist historical materialism points out that theory is a rational social consciousness, and theoretical innovation is the need of the unity of social existence and social consciousness, which cannot be divorced from the objective law that social existence determines social consciousness and social consciousness reacts on social existence. On the basis of material production and spiritual production, people’s understanding of truth is refined and summed up in the cycle from sensibility to rationality to practice. Theoretical innovation must be based on social practice, and the main body of practice is the people. Marxism defines the people’s dominant position in social production practice and points out the "creative" nature of the people in the process of complex social practice. Marxism is a theory that stands for the people and speaks for them. It was founded to change people’s destiny and enriched and developed in people’s practice of seeking liberation. the Communist Party of China (CPC) is a political party guided by Marxism. To promote the party’s theoretical innovation, it must be closely combined with people’s creative practice, which is an inexhaustible source of Marxist theoretical innovation.

　　Looking back on the history of the Party’s struggle for a hundred years, we can see that the reason why our Party has made great achievements in various historical periods of revolution, construction and reform, and has been able to lead the people to accomplish arduous tasks that other political forces in China can’t, lies in mastering Marxist scientific theory and constantly promoting theoretical innovation in light of new realities. He has made great theoretical achievements such as Mao Zedong Thought, Deng Xiaoping Theory, Theory of Three Represents, Scientific Outlook on Development and Socialism with Chinese characteristics Thought of the Supreme Leader in the New Era, and has always adhered to emancipating the mind, seeking truth from facts, advancing with the times, seeking truth and being pragmatic, which has made Marxism glow with great vitality in China and enabled the Party to master a powerful force of truth. The party’s theoretical innovation results all come from people’s wisdom, people’s exploration and people’s creation. Adhering to the people’s supremacy is a profound summary of the Communist Party of China (CPC)’s valuable experience in the past 100 years and an unswerving pursuit of value, which is an important embodiment of Marxist people’s view. History has created the Communist Party of China (CPC) in the people’s exploration and struggle, and the Communist Party of China (CPC) led the people to create new historical glory. During the period of new-democratic revolution, socialist revolution and construction, the Communist Party of China (CPC) people, with Comrade Mao Zedong as the main representative, combined the basic principles of Marxism with China’s concrete reality, insisted on integrating theory with practice and keeping close contact with the masses, and with the strong support and sincere support of the broad masses of the people, absorbed the wisdom of the masses and relied on the strength of the people, and founded Mao Zedong Thought through hard exploration. Comrade Mao Zedong pointed out, "As long as we rely on the people,Firmly believe that the creativity of the people is endless, so trust the people and become one with them, and then any difficulties can be overcome. " In the new era of reform, opening up and socialist modernization, the Communist Party of China (CPC) people continue to rely on the creative practice of the people and lead the cause development with theoretical innovation. At the end of 1970s, the practice of "all-in-one contract" from Xiaogang Village, Fengyang, Anhui Province directly started the rural reform in China. The party’s major theoretical innovations all come from the people’s creative practice, which shows the people’s creative wisdom. Since the 18th National Congress of the Communist Party of China, the people of the Communist Party of China (CPC), with the Supreme Leader as the main representative, have persisted in combining the basic principles of Marxism with the concrete reality of China and the excellent traditional Chinese culture, scientifically answered the major issues of the times such as what kind of Socialism with Chinese characteristics and how to uphold and develop Socialism with Chinese characteristics in the new era, and created the Socialism with Chinese characteristics Thought of the Supreme Leader in the new era. The Supreme Leader’s Socialism with Chinese characteristics Thought in the New Era is contemporary China Marxism and 21st century Marxism, and it is the essence of Chinese culture and China spirit, which has achieved a new leap in the modernization of Marxism in China.

　　3. To promote the theoretical innovation of the Party, we must follow the mass line.

　　To promote the party’s theoretical innovation, we must go deep into the people and do a good job of investigation and research. The people are the creators of history and the decisive force to promote social development and change. Investigation and research is the heirloom of our party, the foundation of seeking things and the way to achieve things. Investigation is the source of insight. Since the 18th National Congress of the Communist Party of China, the CPC Central Committee with the Supreme Leader as the core has attached great importance to investigation and research. The General Secretary of the Supreme Leader took the lead in setting an example and went deep into the people. The footprints of investigation and research spread all over the country, setting a shining example for the whole party to do a good job in investigation and research. Going deep into the people to do a good job in investigation and research is the basis of continuously promoting the theoretical innovation of the Party, and it is also the practical need to keep sober and firm in solving the unique problems of the big party and answer the "six how to always". To promote the party’s theoretical innovation, we must not build a car behind closed doors, sit and talk about the road, and become a pipe dream. The General Secretary of the Supreme Leader stressed, "We should worship the people as teachers, learn from the people, put down our airs, throw ourselves down, be grounded, understand the situation, conduct in-depth investigation and study, dissect sparrows, find typical examples, truly find out the problems faced by the masses, reflect their opinions and sum up the experience created by the masses." The social practice of the masses is not only the object of our investigation and study, but also the inexhaustible source of our correct understanding. The masses not only know the actual situation best, but also contain the wisdom and strength to solve problems. Only by doing a good job of investigation and study can we continuously promote the party’s theoretical innovation.

　　Promoting the Party’s theoretical innovation must respect the people’s initiative. General Secretary of the Supreme Leader emphasized that "we should respect the people’s initiative, pay attention to summing up fresh experiences from the people’s creative practice, upgrade to rational understanding and refine new theoretical achievements". Respecting the people’s initiative is determined by the nature and purpose of our party, which embodies the Marxist historical values. The development of society is always based on giving full play to people’s subjective initiative and respecting people’s initiative. The will, desire, requirement and practice of the people reflect the trend of social development and embody the law of social development. At present, the changes of the world, times and history are unfolding in an unprecedented way. The "two overall situations" are accelerating and interacting deeply. China’s development has entered a period in which strategic opportunities and risk challenges coexist and uncertainties and unpredictable factors increase. It is even more necessary for us to persist in taking the people as the center, respect the people’s initiative, fully stimulate the creative power contained in the people, pay attention to the unity of top-level design and consultation with the people, and constantly gain new understanding from summing up the people’s creative practice.

　　Let the party’s innovative theory penetrate into the hearts of hundreds of millions of people. Report to the 20th CPC National Congress pointed out that it is necessary to "build a socialist ideology with strong cohesion and leading power" and "improve the system of arming the whole party, educating the people and guiding practice with the Party’s innovative theory". If great thoughts want generate’s great strength, they must be transformed into concrete social practice, rely on the people as the main body of social practice, and make the innovation theory consciously recognized and sincerely supported by the people, making it a powerful ideological weapon to guide the people to understand and transform the world. General Secretary of the Supreme Leader stressed, "Insist on inner-party education to guide and drive the learning of the whole society, and let the party’s innovative theory ‘ Fly into the homes of ordinary people ’ " . Socialism with Chinese characteristics Thought of the Supreme Leader in the New Era is contemporary China Marxism and 21st century Marxism, and it is the essence of Chinese culture and China spirit. We should persist in casting our souls with Socialism with Chinese characteristics Thought of the Supreme Leader in the new era, carry out in-depth study, publicity and interpretation in the whole party and society, guide the broad masses of party member, cadres and the masses to deeply understand the decisive significance of the "two establishment", strengthen the "four consciousnesses", strengthen the "four self-confidences" and achieve the "two maintenance".Consciously maintain a high degree of unity with the CPC Central Committee with the Supreme Leader as the core in ideological and political actions, and unite and struggle for building a socialist modern country in an all-round way and promoting the great rejuvenation of the Chinese nation in an all-round way. It is necessary to establish a people-centered work orientation, combine serving the people with guiding them to learn the Party’s innovative theory, grasp the theoretical concerns of the people, constantly innovate theoretical propaganda methods, and strive to make the Party’s innovative theory penetrate into the hearts of hundreds of millions of people and become a theory that is grounded, gathers people’s wisdom, conforms to the will of the people, and wins the hearts of the people, bringing together the majestic forces for building a socialist modern country and comprehensively promoting the great rejuvenation of the Chinese nation.

　　Recently, mycoplasma infection and mycoplasma pneumonia have become high-frequency words in mom circle. Three years after the epidemic in COVID-19, before the arrival of mycoplasma infection, children have experienced several rounds of infectious diseases, which are influenza, syncytial virus infection, infectious diarrhea, herpetic angina and so on. From the beginning of school in March this year to the present, "one disease per month" children account for a considerable proportion.

　　The epidemic time of mycoplasma was advanced, and it spread widely.

　　During the epidemic in COVID-19, because everyone wears masks, washes hands frequently, keeps social distance, increases ventilation and disinfects more surfaces, children’s contact with other pathogens is reduced, and the incidence of virus and bacterial infections is reduced. However, everything has two sides. The decrease of infection makes the immune stimulation of pathogens insufficient, the susceptible population increases and the group immunity decreases. After reducing the intensity and scale of group protection in many countries, the incidence of respiratory syncytial virus and other pathogens increased significantly. In this context, experts put forward the concept of immune debt during COVID-19 (the above content was quoted from the No.1 issue of journal of applied clinical pediatrics Journal of China, Volume 38, January 2023, "Immune debt and its influence during the epidemic of children in novel coronavirus").

　　To put it simply, COVID-19’s three-year-old children may get one disease at a time. The flu hit first, and now it’s mycoplasma’s turn.

　　Mycoplasma is a prokaryotic microorganism similar to bacteria but without cell wall, which is between bacteria and viruses, smaller than bacteria and larger than viruses, and is the main pathogenic microorganism of respiratory tract infection. Most common mycoplasma epidemics occur in November and December every year, and this year is advanced to August and September, which affects a wider range of people. The children’s condition is biased and the course of disease is long.

　　Mycoplasma pneumonia has typical characteristics, and children should be vigilant in the following situations.

　　1. Severe irritating dry cough: Severe cough is a prominent symptom of this disease. At the beginning, it is a dry cough, and the cough is stubborn and severe. The child can’t stop coughing and even affect the activities during the day and sleep at night. Late sputum, cough is still severe.

　　2. Fever: high fever is common. If not treated, the fever will persist. There are also people with low body temperature or even no fever, which are relatively few.

　　3. Auscultation often does not hear rales: general doctors with lung infections can hear wet rales, but most of mycoplasma pneumonia can’t hear rales. The auscultation of the lung is very inconsistent with the clinical manifestations such as severe cough and high fever, which has become one of the characteristics of this disease. Therefore, the diagnosis of mycoplasma pneumonia often needs chest radiography to assist the diagnosis.

　　4. Chest X-ray: Typical mycoplasma pneumonia often shows large shadows in the lungs.

　　5. Routine blood test: Routine blood test of mycoplasma has no characteristics, unlike typical bacterial infection, where the total number of white blood cells, neutrophils and CRP are all increased, and unlike virus infection, which is basically normal, white blood cells are often normal or high, or one of them is high.

　　6. Mycoplasma pneumoniae antibody test: Mycoplasma antibody test positive can help diagnosis, but negative can not be excluded. And mycoplasma antibodies are often not detected at the early stage of the disease, which is not helpful for early diagnosis.

　　These are the characteristics of typical mycoplasma pneumonia, but actually not all mycoplasma pneumonia show these characteristics. Clinically, some children only have a high fever and their cough is not obvious. In the clinic, I once met a child who had a fever for 5 days, accompanied by a mild cough for 2 days, and a film was also pneumonia. Some children have no obvious fever, only moderate to low fever, and even have no fever but cough is very severe, and filming is also pneumonia.

　　About mycoplasma infection, these problems should be clear.

　　Will children get pneumonia if they are infected with mycoplasma? Mycoplasma pneumonia is very difficult, okay? Will there be sequelae? Parents have too many questions to answer.

　　First of all, it should be noted that infection with mycoplasma (mycoplasma pneumoniae) does not necessarily lead to pneumonia. Mycoplasma (mycoplasma pneumoniae) can not only cause pneumonia, but also cause upper respiratory tract infection (common cold symptoms) and tracheitis.

　　Which children are susceptible to mycoplasma (mycoplasma pneumoniae) infection? Mycoplasma pneumoniae mainly infects children aged 5-9, that is, school-age children. Recently, this wave of mycoplasma infection has spread to a wider age group, and infants also have severe mycoplasma pneumonia.

　　How to treat mycoplasma pneumonia? Once mycoplasma pneumonia is diagnosed, macrolide drugs such as erythromycin and azithromycin are given for treatment. Mycoplasma infection is not sensitive to penicillins and cephalosporins.

　　Why do children still progress to pneumonia after taking azithromycin? Is it delayed? Azithromycin is a specific drug for treating mycoplasma infection. Some children took azithromycin orally in the early stage of fever, but their condition was still getting worse and more serious pneumonia appeared. Parents often don’t quite understand why they developed pneumonia after taking azithromycin at the early stage of taking their children to see a doctor. The reason for this is complicated, which may be related to the variation or drug resistance of mycoplasma. It may also be related to the child’s poor rest after illness, or to the child’s physique.

　　Mycoplasma pneumonia is very difficult, okay? Will there be sequelae? Mycoplasma pneumonia has a good prognosis after regular treatment. However, there are also serious mycoplasma pneumonia, and the effect of antibiotic treatment is not ideal, so special drugs such as hormones are needed, and some need bronchoscopy to assist diagnosis and treatment.

　　If mycoplasma pneumonia is diagnosed, the child should be treated completely according to the doctor’s requirements, and hospitalization is needed if necessary. Have a good rest during and after the treatment, and don’t take classes with illness. After the treatment, you need a rest period.

　　How to prevent mycoplasma pneumonia? When the child is at school, the class should actively open the window for ventilation; Children should carry out appropriate physical activities to increase immunity; Don’t arrange extracurricular classes and physical classes too full, but step by step, so that children can have an adaptation process; Drink plenty of water, don’t eat too much, and ensure daily defecation. Daily ventilation should be ensured in the family. If children have mycoplasma infection, isolation should be implemented as much as possible to reduce cross-infection in the family.

　　Cctv newsAt present, the domestic epidemic situation is scattered at many points, and the number of imported cases continues to increase, which further increases the risk of imported epidemic situations outside Beijing and outside Beijing. Some close contacts, on the way back to Beijing by train, plane and other public transport, are close to or overlap with the seats of the confirmed cases, because they wear N95 masks regularly, don’t eat, walk less and talk less, and do personal protection all the time, and finally they are not infected. Protect yourself and protect your family.

　　The Beijing Center for Disease Control and Prevention reminded people returning to Beijing to raise their awareness of prevention and control and do a good job of personal protection on their way back to Beijing..

　　Before returning to Beijing

　　★　Personnel entering and returning to Beijing should strictly implement the epidemic prevention policy.Plan your trip in advance., minimize transit.

　　★　　Prepare enough protective materials such as masks and hand-washing-free disinfectants.

　　★　　It is not recommended to travel for people who feel unwell, especially those who have respiratory symptoms such as fever and cough. Especially for the elderly, pregnant women and special people with chronic diseases, it is recommended to ask professional doctors to evaluate their health before deciding whether to travel.

　　On the way back to Beijing

　　★　　Personal protection throughout the process.. Adhere to scientific and standardized measures to prevent and control the normalized epidemic situation, such as wearing masks, washing hands frequently, often ventilating, and keeping a safe social distance.

　　★　Cooperate with transportation departments such as railways, civil aviation, passenger transport, and road checkpoints, and strictly implement various prevention and control measures such as temperature measurement and code inspection and inspection of nucleic acid certificates in accordance with relevant regulations.

　　★　When waiting for a bus, try to wait in a well-ventilated space, and do not stay in a crowded, closed place with dirty air for a long time. Do a good job of personal protection.

　　★　　Pay attention to hand hygiene after using public facilities such as toilets and elevators.

　　★　　When taking airplanes, trains and other means of transportation,It is necessary to wear masks in a standardized way throughout the journey, minimize walking, reduce contact with others, and reduce the frequency of meals., reduce the risk of infection.

　　★　　When dining out, you should pay attention to eating at the wrong peak and choose a ventilated place to sit. Try to sit down at intervals or eat on the same side. When two or more people eat together, they should use public chopsticks and spoons.

　　After returning to Beijing

　　★　Those who enter and return to Beijing need to hold the negative nucleic acid certificate within 48 hours and the green code of "Beijing Health Treasure" to strictly abide by various epidemic prevention regulations.

　　★　Personnel returning to Beijing in risk areas should take the initiative to report to communities, units, hotels and other departments in a timely manner and cooperate with various epidemic prevention measures such as isolation observation, health monitoring and nucleic acid detection.

　　★　Carry out 3 days and 2 inspections.That is, one nucleic acid test is completed within 24 hours after arrival in Beijing, and the second nucleic acid test is completed within 72 hours after the interval of 24 hours.No dinner, no party or going to crowded places within 7 days.Do not visit relatives and friends, recommend online shopping, reduce going out before the negative result of nucleic acid test, and do personal protection when going out.

　　★　Pay close attention to the health of yourself and your family.Once you have symptoms such as fever, dry cough, fatigue, sore throat, decreased sense of smell, diarrhea, etc., don’t buy medicine by yourself, don’t take public transportation, and seek medical treatment in time according to regulations.

[ITBEAR] Recently, the state’s support for the new energy automobile industry has continued to increase, and a series of policies and measures aimed at promoting the development of electrification, intelligence, networking and sharing (referred to as "new four modernizations") have been introduced one after another, injecting strong impetus into the market. Among them, the subsidy policy of automobile trade-in has become the focus of consumers’ attention, and its market effect is remarkable.

The positive signal recently released by the National Development and Reform Commission is even more exciting for consumers, and the national subsidy policy is expected to continue to be implemented in the future, which undoubtedly provides more expectations for consumers who are interested in buying cars. According to the relevant person in charge of the National Development and Reform Commission, the support for the "two new" policies will be further increased in the future, and a new round of large-scale equipment renewal and trade-in of consumer goods will be promoted, and the subsidy policy for trade-in in the automobile field will play an important role.

Major car companies actively responded to the call of the state and introduced preferential policies for car purchase in succession, in order to get a share of the dividend of the state subsidy policy. From the replacement subsidy policies introduced by Cadillac, Star Road Star Era and Volvo at Guangzhou Auto Show to the active participation of brands such as Wuling Automobile, the market competition has become increasingly fierce. Car companies attract consumers’ attention by increasing subsidy amount, optimizing car purchase process and improving service quality, and strive to stand out in the fierce market competition.

However, while enjoying the policy dividend, consumers also need to pay attention to the specific implementation details of relevant policies. Although the National Development and Reform Commission has clearly stated that the state subsidy policy will continue, the specific subsidy standards and rules have not yet been finalized. When consumers apply for subsidies, they also need to prepare car purchase invoices, driving licenses and other relevant supporting documents to ensure the smooth receipt of subsidies.

For consumers who have not yet bought a car, the continuation of the national subsidy policy is undoubtedly good news. They can pay close attention to the policy trends, understand the preferential activities of car companies, and plan the car purchase plan in advance, so as to buy a car at the right time and enjoy the benefits brought by the policy.

On March 7 th, the progress of Tesla FSD (fully autonomous driving) has always been a point of great concern to the outside world. Now, more news about the landing of FSD Beta has been revealed. According to related news, Tesla FSD will land in the European market in 2025, and it is also advancing rapidly in China, and it is expected to be released this summer.

It is pointed out that the European Union adopted relevant new regulations at the just-held World Vehicle Regulations Coordination Forum, and according to this new regulation, it is confirmed that Tesla FSD European version will land in the European market in 2025, and in October this year, Tesla FSD Beta test will start testing in the European Union.

In China, the China version of Tesla FSD Beta is also advancing rapidly. It is reported that the goal is to be officially released this summer. In November last year, four ministries and commissions jointly issued a notice to deploy and carry out the pilot work of intelligent networked vehicle access and road traffic. At that time, Tesla FSD was considered to have entered the countdown stage.

Earlier, in May last year, Chen Kele, deputy director of the Intelligent Manufacturing Promotion Department of Shanghai Economic and Information Committee, said: In the next stage, Shanghai will further deepen its cooperation with Tesla, promote the layout of functional sectors such as autonomous driving and robots in Shanghai, and jointly build a technology industry cluster with core technological advantages and facing the global market. This also makes us believe that the landing of Tesla FSD in China is indeed just around the corner.

Tesla FSD, the full name of which is Full Self-Drive, means fully automatic driving. At present, Tesla has launched three assisted driving products, namely AP, EAP, and FSD, among which AP is the most basic and EAP is to enhance assisted driving, which can provide intelligent calling, automatic parking, NOA and other functions. These two functions can be used in China at present.

As Tesla’s highest-level assisted driving ability, FSD can provide navigation-assisted driving, automatic lane change, automatic parking, intelligent calling, traffic signal recognition and other functions. Up to now, only the Beta version has been provided in North America. But in fact, these capabilities are already possessed by major domestic new energy brands and have been used on the road. In this respect, Tesla is indeed a little behind. I believe that Tesla is also actively responding to ensure the early landing of FSD in China, which will also bring new revenue to it. We will continue to pay attention to this.

Adhering to the people-centered principle is one of the basic strategies for upholding and developing Socialism with Chinese characteristics in the new era. Community is the most basic living place for people, and the starting point of community planning and construction is the vital interests of the grassroots. In August, 2020, 13 departments, including the Ministry of Housing and Urban-Rural Development, jointly issued the Opinions on Carrying out the Short-board Action of Urban Residential Community Construction, and at the same time issued the Standard for the Construction of Complete Residential Community (Trial), which clearly stated that the goal is to build a safe, healthy, well-equipped and well-managed complete residential community, and the supporting facilities of residential community should be improved as the focus, and the short-board action of residential community construction should be vigorously carried out. Residential community is the basic unit of urban residents’ life and urban governance, bearing the people’s hopes for a better life. It is of great significance to comprehensively improve the quality and service level of infrastructure construction in residential communities to enhance people’s sense of acquisition, happiness and security.

Foundation first, improve people’s basic needs for a better life

Infrastructure such as water, electricity, gas, heat and communication is an important guarantee for the normal life of community residents. Due to the early construction, the problems such as the erection of wires from a distance and the aging of pipelines have not only brought serious troubles to the lives of some residents in old communities, but also caused a huge waste of resources and energy. In July 2020, the General Office of the State Council issued the Guiding Opinions on Comprehensively Promoting the Renovation of Old Urban Residential Areas (hereinafter referred to as "Guiding Opinions"), which clearly stated that starting from the most direct and realistic interests that the people are most concerned about, the residents’ opinions should be solicited and the renovation contents should be reasonably determined, and the supporting facilities of residential areas and municipal infrastructure should be improved. In the process of community transformation, we should adhere to the principle of "underground first, then above ground", give priority to the transformation of underground pipelines such as water supply, rainwater, sewage, gas, electricity and communication, and upgrade public infrastructure such as roads, fire protection, charging, lighting and domestic waste sorting. Implement the concept of sponge city, protect and restore the community ecosystem, build a sponge community, effectively combine natural channels with manual measures, comprehensively adopt the measures of "infiltration, stagnation, storage, purification, use and discharge", and carry out roof greening, rainwater storage and collection and utilization, and micro-topography construction according to local conditions through combined design, so as to scientifically and orderly promote the transformation of rainwater and sewage diversion and mixed connection in the community with separate system, and maximize the realization of rainwater in the residential community. Actively promote the classification of domestic waste, improve the facilities for classified delivery, classified collection and classified transportation, and at the same time strengthen publicity to make the awareness of garbage classification deeply rooted in the hearts of the people.

The Guiding Opinions pointed out that by the end of the Tenth Five-Year Plan period, we should strive to basically complete the task of rebuilding old urban communities that need to be rebuilt before the end of 2000 in light of local conditions. As far as the current situation is concerned, the task of transformation is arduous. On the one hand, it is necessary to ensure capital investment and establish a long-term mechanism. The government, residents and social forces should share the burden reasonably and improve the long-term management mechanism of the community. On the other hand, community residents and professional and technical personnel should participate extensively, encourage planners and engineers to enter the community, improve the renovation design and refined governance level of old residential areas, promote the construction and renovation of community human settlements in a simple, moderate, green and low-carbon way, and strive to improve the functional quality of the community.

Overall coordination to ensure the healthy circulation of urban water system

Urban water system is a comprehensive system based on water cycle, water flux as the medium, water facilities as the carrier, water safety as the goal and water management as the means. Residential community is the spatial carrier of domestic water and sewage discharge of the broad masses of people, an important place for the conversion of material flow and energy flow, and a key node of urban water system. At present, the overall efficiency of urban water system in China needs to be improved. According to the Statistical Yearbook of Urban Construction in 2020 published by the Ministry of Housing and Urban-Rural Development, the leakage of urban public water supply network in China is about 7.85 billion cubic meters, accounting for about 13% of the total urban public water supply, which is still far from the goal that the leakage rate of water supply network is less than 10% in the Outline of Industry Development Plan for Urban Water Affairs in 2035. The concentration of influent biochemical oxygen demand (BOD) in some sewage treatment plants in China is less than 100 mg per liter. It is urgent to systematically investigate the reasons for the low influent concentration around the pipe network in the service area and steadily improve the efficiency of sewage collection and treatment facilities. Due to the influence of extreme climate and the imperfect drainage and waterlogging prevention engineering system, urban waterlogging incidents occur from time to time, and the urban drainage and waterlogging prevention engineering system of "source emission reduction, pipe network discharge, simultaneous storage and drainage, and emergency exceeding the standard" needs to be improved urgently.

The upgrading and transformation of community infrastructure should not only meet the basic service needs of community residents, but also organically combine with the overall improvement of municipal facilities system functions, and implement the overall layout and policy requirements of the state on improving the quality and efficiency of each subsystem of urban water system. In terms of urban water supply, the General Office of the Ministry of Housing and Urban-Rural Development issued the "Guidelines for the Measurement and Management of Urban Water Supply Pipe Network by District-Construction of Water Supply Pipe Network Leakage Control System" (for Trial Implementation) in 2017, guiding local governments to take the measurement and management of urban water supply pipe network as the starting point, strengthen the leakage control of urban water supply pipe network with systematic ideas, improve the level of refined and information management of water supply pipe network, and enhance the ability of water supply security. In practice, we should combine the construction of complete community, the renovation of old residential areas, the renovation of shanty towns and the renovation of secondary water supply facilities, formulate the implementation plan of metering management in different areas of the pipe network according to local conditions, design and implement it synchronously with the construction and renovation of the pipe network, coordinate water metering and water pressure control, water quality safety and facilities management, pipe network operation and business charge management, and build a pipe network leakage control system. In terms of urban sewage treatment, the National Development and Reform Commission and the Ministry of Housing and Urban-Rural Development in 2020 issued the "Implementation Plan for Supplementing Shortboards and Strengths of Urban Domestic Sewage Treatment Facilities", which clearly proposed to combine the renovation of old residential areas and municipal roads, promote the connection construction of branch pipe networks and outdoor pipes, supplement "capillaries", and implement mixed connection, missed connection, and renovation of old and damaged pipe networks to improve the efficiency of sewage collection. In terms of urban waterlogging control, the General Office of the State Council issued the Implementation Opinions on Strengthening Urban Waterlogging Control in 2021.It is clearly put forward that priority should be given to solving the problems of waterlogging in residential communities, mixed connection of rainwater and sewage pipe networks, etc. By disconnecting the rainwater pipes of buildings, optimizing the vertical design, and strengthening the elevation connection of buildings, roads, green spaces, landscape water bodies, etc., rainwater overflow can be discharged into drainage pipe networks, natural water bodies or recycled after collection.

Green and low carbon help the city achieve the goal of "double carbon" as scheduled.

Realizing peak carbon dioxide emissions and carbon neutrality is an important strategic decision made by the CPC Central Committee with the Supreme Leader as the core, an inevitable choice to solve the outstanding problems of resource and environment constraints, realize the sustainable development of the Chinese nation, and a solemn commitment to build a community of human destiny. In October, 2021, the State Council issued "peak carbon dioxide emissions Action Plan before 2030", which clearly stated that the green production lifestyle was widely implemented during the Tenth Five-Year Plan period. Building green towns and communities. From the international experience, the improvement of residents’ quality of life will push up the per capita carbon emission level, and the essence of community renewal and transformation is to improve residents’ quality of life, and to actively intervene in green technology and green lifestyle to prevent the future increase of community carbon emissions. At the community level, the primary goal is to realize people’s high-quality life, and at the same time, we should popularize green lifestyles such as water saving, garbage sorting and food saving, enhance residents’ acceptance of green lifestyles, and ensure the smooth implementation of the national "double carbon" strategy. In the process of community infrastructure renovation, franchise units should seize the important opportunity of community renovation and old residential area renovation, speed up the renovation of underground pipe network, adopt new sewage collection and rainwater utilization technologies, comprehensively improve the efficiency of infrastructure operation system, and reduce the background energy consumption and carbon emission level of infrastructure operation in the community. Promote green technologies such as the integration of plants, networks and rivers, the utilization of reclaimed water and the management of non-profitable water, strengthen the construction of smart water, and realize the systematic carbon emission reduction of urban water system from the source to the end of the community. Code for Design of Outdoor Drainage(GB50014-2021) clearly requires that when sewage collection and centralized treatment facilities have been built in cities and towns, septic tanks should not be set in the separate drainage system. Septic tanks will not only intercept COD (carbon source) and affect the influent concentration of sewage treatment plants, but also anaerobically convert the intercepted COD into greenhouse gases such as methane. At present, the urban sewage treatment rate in China has reached 97.53%. In the process of community sewage facilities renovation, canceling the septic tank construction according to local conditions can not only reduce the renovation cost and urban greenhouse gas emissions, but also increase the influent concentration of sewage treatment plants and improve the operation efficiency of sewage treatment plants.

Scientific evaluation and building the bottom line of residential community safety

At present, China’s urban construction has entered a new stage of stock-based and high-quality development. Problems such as aging stock infrastructure, overloaded operation and untimely operation and maintenance may cause disasters and accidents. In 2021, the National Development and Reform Commission and the Ministry of Housing and Urban-Rural Development issued the "Notice on Strengthening the Construction of Supporting Facilities for the Renovation of Old Urban Residential Areas", clearly requiring the organization of relevant professional business units to jointly investigate the possible safety hazards of supporting infrastructure such as gas, electricity, drainage and heating, and public spaces. Safety is no small matter, and responsibility is greater than heaven. Community infrastructure construction should be based on security, expand the connotation of resilience, and integrate the concepts of intensive, green, intelligent and collaborative to build an infrastructure security system to help the high-quality development of the city. Safety awareness should run through the whole process of building a complete community and transforming old communities. In the process of compiling the community renewal and transformation plan, facilities such as gas, electricity, drainage and heating with potential safety hazards should be given priority as key contents. Involving gas, electricity, drainage, heating and other security risks, we should ensure that the security review does not leak items. Professional business units should implement safety responsibilities, strengthen the protection of construction and operation and maintenance forces, and eliminate potential safety hazards. Make full use of the Internet, big data, artificial intelligence and other information technologies, promote the construction of community intelligent disaster prevention and mitigation system, promote the sharing and application of data related to disasters and accidents, and accelerate the construction of community disaster comprehensive monitoring and early warning perception network and terminal equipment.

The report of the 19th National Congress of the Communist Party of China proposed to promote green development and carry out actions to create green communities. Green community is an inevitable choice for the development of modern cities and an important part of building beautiful China. The construction of green community should combine urban renewal and upgrading of existing housing, implement the concept of sponge city, integrate resilience elements and wisdom elements, realize the greening of community infrastructure, promote the improvement and sustainable development of municipal infrastructure system, and build urban ecological infrastructure system, so as to continuously improve people’s sense of acquisition, happiness and security.

　　A few days ago, the newspaper "Don’t let students play" soft ball "aroused the concern of the society about students’ physical health. Yesterday, after interviewing some schools, the reporter found that many PE teachers were afraid to take part in sports for fear of accidental injuries to students. Traditional sports such as "jumping goats" and single parallel bars are quietly withdrawing from primary and secondary schools in physical education class.

　　Afraid of students being injured, they dare not go to the project.

　　A physical education teacher in the city told the reporter that his school has not participated in the jumping box project for many years. On the surface, it is more troublesome to prepare before class, and the mat is also a box, but the more important reason is that students are afraid of injury. "Especially primary school students can’t stand it, and they can fall out with a wrong eye."

　　The teacher’s "jumping box" is commonly known as "jumping goat", and most people over 30 years old have practiced it on the physical education class in their student days. This project is mainly to train students’ ability to overcome obstacles, and also to test students’ psychological quality. Under normal circumstances, senior primary school students should learn "goat prancing with split legs", junior high school students and senior high school girls should learn "horizontal box prancing with split legs" and "horizontal box prancing with bent legs", while senior high school boys should learn "vertical box prancing with split legs" and "vertical box prancing with bent legs". However, up to now, few schools offer this program.

　　The events with the same fate as "Bouncing Box" include the single parallel bars. A physical education teacher with more than 20 years’ teaching experience said that he had never started this project since he entered the profession. At first, the school didn’t have the venue conditions, but later he dared not take it, for fear that students would be injured. "Today’s children can’t really talk. They didn’t last for a few seconds, either their arms were twisted or their shoulders were twisted, and wrist fracture’s children couldn’t attend class … …” The teacher repeatedly expressed his feelings.

　　Change the content to avoid disputes.

　　Physical education teachers are afraid to take part in the project, fearing the disputes that may be caused by students’ exercise injuries.

　　A physical education teacher told the reporter about his experience. Once, he gave a class to a fifth-grade student. A student fell down while running 50 meters. At that time, he asked if the child was injured. The child said that he was fine, but his arm was red and swollen after returning to work. The class teacher called the parents. Later, parents were adamant. First, they complained that the teacher didn’t send their children to the hospital at the first time. Later, they said that their children were made for the air force, and injuries would affect their future service as soldiers. The physical education teacher had no choice but to make amends at home every three days until his parents cooled down.

　　It is understood that schools encounter such disputes in different ways. Some schools will pay children’s medical expenses, but some schools will let PE teachers bear the consequences themselves, which will bring pressure to PE teachers invisibly.

　　In order to avoid disputes, many PE teachers have to reduce their own risks without violating the syllabus. For example, there are gymnastics teaching contents in the syllabus, but the teachers no longer take the single and parallel bars, but only use relatively simple movements such as forward roll, back roll, horizontal fork and vertical fork instead. Even the most common winter long-distance running events, many schools have to issue a "parents’ notice" before the start of the race, so that parents can confirm whether their children can participate in this sport, so as to avoid being "accounted for" after the accident.

　　New monitoring and evaluation standards are brewing.

　　I am afraid that my child will be injured and dare not go to the project. Is this for the sake of my child or for the sake of my child?

　　In this regard, Li Xiangru, a professor at Capital Institute of Physical Education, believes that the decline of primary and secondary school students’ physical fitness and ability to adapt to society is related to the lack of challenging events in physical education class. We should not regard physical education class as a simple physical education class, but link physical education class with the all-round development of teenagers.

　　In his view, the physical education curriculum in primary and secondary schools should be reformed around "what kind of teenagers should be trained". In this process, it is necessary for young people to enhance their ability to resist blows, setbacks and injuries in physical exercise. From a certain point of view, failing to get on the "dangerous project" tests the responsibility of primary and secondary school principals and physical education teachers.

　　As for the fear of students’ injuries, he feels that among all disciplines, physical education class is a high-risk course, and minor injuries are inevitable in sports. As long as physical education teachers are not negligent, they should not be held accountable to physical education teachers. "Students’ injuries should be viewed objectively, not necessarily the problems of schools and teachers."

　　In addition, the reporter learned from relevant departments that the Municipal Education Commission, the Municipal Sports Bureau and the Municipal Center for Disease Control and Prevention are preparing the "Evaluation Standard for physical education class Exercise Load of Primary and Secondary School Students in Beijing", with a view to monitoring and evaluating the quality of physical education class in primary and secondary schools by issuing local standards. If it goes well, the standard is expected to be officially introduced next year.

　　When I saw Chen Shuguo, he was standing on the coast, guiding the students around him and testing the drone.

　　"Our job is to serve the ocean ‘ Have a physical examination ’ 。” Hand over the remote control of the drone to the students. The young associate professor said, "If you want to develop, utilize and study the ocean, you must first know it and understand everything ‘ Physical examination index ’ . China’s offshore marine atmospheric environment is very complicated. Although China’s autonomous ocean color satellite remote sensing technology has developed rapidly in recent years, how to process the data can be more accurate, and how to determine the error and correct it are all problems we are committed to solving. "

　　Chen Shuguo, 37, is an associate professor and doctoral supervisor at Sanya Institute of Oceanography, China Ocean University, and a part-time researcher at the National Satellite Ocean Application Center. He has been studying marine optical remote sensing for more than ten years, and the on-orbit alternative calibration algorithm of marine optical satellites developed by his team is serving the operational calibration system of China’s independent marine color satellites Haiyang-1 C and Haiyang-1 D. In recent years, Chen Shuguo is in charge of the project "Technical Development of Synchronous Observation System for Marine Water and Atmosphere", which has realized long-term, continuous and stable observation of optical parameters of water and atmosphere, and will be applied to the inspection of marine remote sensing products of Haiyang-1 series satellites and a new generation of water color observation satellites.

　　Calibration of marine optical satellites to make data more comprehensive and accurate.

　　Chen Shuguo became attached to marine optical remote sensing in 2009. That year, he was admitted to China Ocean University as a postgraduate majoring in marine information detection and processing, and saw the sea for the first time.

　　"I am determined to engage in academics." Chen Shuguo’s academic enthusiasm has never wavered since he first entered school. After graduating from Ph.D., he continued to stay at his alma mater to study the basic theory and innovative application of marine optics.

　　"When the sun shines on the water, some of it is reflected, some of it enters the water and is absorbed, and some of it will be scattered. Remote sensing of ocean water color is to analyze the spectral characteristics by receiving these scattered energy and deduce the optical composition of water body. " Chen Shuguo explained, "These detection data play an important role in China’s maritime rights and interests maintenance, marine resources development, marine environmental monitoring and marine disaster prediction."

　　The most efficient and effective way to observe the ocean by remote sensing is to launch ocean satellites. Since the launch of the first ocean color test satellite, Ocean No.1 A, in 2002, China’s ocean satellites have developed for 20 years, and China’s autonomous ocean satellite optical remote sensor is also moving towards the "last mile" of full autonomy.

　　Calibration refers to the process of converting satellite observation data into real radiation. "If satellite observation is a pole ‘ Scale ’ , then calibration is to add ‘ Sight ’ The process can make satellite data more accurate. " Chen Shuguo said, however, for a long time, we have to improve the calibration algorithm and lack the necessary calibration infrastructure.

　　In order to solve this problem, Chen Shuguo settled down and studied hard. Reading literature, publishing papers, leading teams to conduct on-the-spot observation and experiments … … "We have conducted more than 20 voyages of marine optical comprehensive experiments on different types of water atmospheric environment." Chen Shuguo said that a large number of first-hand data have laid a solid foundation for follow-up research.

　　While doing theoretical deduction and finding the best algorithm, the site selection of calibration field is determined through comprehensive analysis of a large number of data. One month before the launch of Haiyang-1 C satellite, Chen Shuguo led a team to develop an on-orbit alternative calibration algorithm for China autonomous ocean color satellite.

　　After years of field observation, the swaying deck is the second laboratory.

　　Ocean optics and water color remote sensing are disciplines based on field measurement. In order to obtain comprehensive field observation data of ocean optics, Chen Shuguo has worked in the observation line for many years, taking the swaying deck as the second laboratory and writing papers on the ocean.

　　For Chen Shuguo, the sea is an unpredictable "old friend". Although he has been dealing with it for more than 10 years and knows it better than others, Chen Shuguo is still looking forward to and uneasy every time he puts the observation instrument into the water for measurement. "Ocean observation not only has bad sea conditions, but also is accompanied by various unknown factors underwater. Changing all the time is the essence of the ocean. "

　　Observation at sea, a voyage is about 20 days. Due to the heavy scientific research tasks, Chen Shuguo once slept less than 4 hours a day on several voyages. Up to now, Chen Shuguo has been at sea for more than 300 days, of which the longest time has been 74 days in the western Pacific Ocean. "Which marine is not ready to bear hardships?" Chen Shuguo said.

　　Love is dedicated to the sea, and the sea is also fruitful. In 2020, Chen Shuguo began to be responsible for the project "Technical Development of Synchronous Observation System for Marine Water and Atmosphere" of National Satellite Ocean Application Center. This project will set up eight inspection systems with long-term continuous monitoring capability of optical properties of marine water and atmosphere along the coastline of China, which can realize long-term, continuous and stable observation of optical parameters of water and atmosphere under unattended conditions.

　　From the calibration algorithm of China autonomous ocean color satellite to the construction of synchronous observation system of ocean water and atmosphere, Chen Shuguo’s dream of deep blue has never stopped.

　　Down-to-earth, really do some original work.

　　In the winter of 2019, Sanya Ocean Research Institute of China Ocean University held an unveiling ceremony and officially settled in Yazhouwan Science and Technology City, Sanya. In May 2020, Chen Shuguo came to the South China Sea from the Yellow Sea.

　　"We want to build a calibration field for marine water color satellites. The seawater in the South China Sea is cleaner, and the complexity of the coastal water atmosphere is not so high." After joining Sanya Oceanographic Research Institute, Chen Shuguo took the lead in building a remote sensing calibration laboratory for ocean color, which can not only effectively support the maintenance of China’s independent ocean color satellite system to replace the calibration field, but also serve the calibration of marine optical instruments in universities and research institutes and ensure the accuracy of measured data.

　　Today, Chen Shuguo’s students are located in Qingdao and Sanya, and some senior students are internship at the National Satellite Ocean Application Center in Beijing. "Every time we have an online group meeting ‘ Longitudinal span ’ In the north and south, some people are attending classes at school, some are studying in the laboratory, and some are internship in the center. " Chen Shuguo said with a smile, "Learning while thinking and practicing, Industry-University-Research is integrated."

　　The ocean is a huge treasure house of resources, and building a maritime power is a major strategic task to realize the great rejuvenation of the Chinese nation. More than 20 years ago, China didn’t have its own ocean satellite, so it was necessary to buy data from abroad to understand the atmospheric situation of China’s offshore water bodies. Nowadays, groups of scientists are working together to promote the high-level self-reliance and self-improvement of marine science and technology. China marine satellites have entered the era of networked observation, which has not only formed the continuous high-frequency observation coverage of global sea areas, but also the data has the same accuracy as international advanced products. "Doing your job seriously is the greatest contribution to the country." Chen Shuguo said.

　　Jinan, Oct. 10 (Reporter Zhang Xiaoyan Wang Huang) There are many tourists who choose to come to Jinan during the 11th holiday, and Baotu Spring is one of the must-see attractions when coming to Jinan. On October 4th, a netizen posted that Weibo saw a water pump and a transformer box near Baotu Spring in Jinan, questioning the gushing of Baotu Spring in Jinan. By 7: 00 pm on the 10th, the Weibo content had been forwarded for 308 times with 334 comments. On the 10th, the staff of Baotu Spring Scenic Area said that Baotu Spring spewing was a natural phenomenon.

　　On October 4th, a netizen named "Lang Qibo" in Weibo posted a list of people taking photos of tourists by Baotu Spring in Weibo. The spring eyes rumbled outward, and I heard the sound of a water pump from all directions. I found the distribution box by following the sound. Listening to this sound, the quality of the water pump is still good. I don’t know if it is an imported pump or a domestic pump. " It is equipped with three pictures, one of which is a distribution box in the scenic spot.

　　"I live near Baotu Spring, which is a real spring. Don’t mislead tourists and netizens." Weibo published by Lang Qibo quickly attracted comments from many netizens, and everyone left messages on his Weibo to show the authenticity of Baotu Spring in Jinan. However, many netizens’ messages did not dispel "Lang Qibo’s doubts about the gushing of Baotu Spring in Jinan. @ Sincerely and diligently, Jinan’s abundant rainfall and water volume have naturally increased greatly this year. You don’t know that the daily TV news will report the situation of staff monitoring water volume in real time, and you probably haven’t heard of the words "saving water and protecting springs"! @ Livefa _0′ s spring farm message, Jinan has a lot of rain this year, and the groundwater supply is very sufficient. Not only Baotu Spring, but also 72 springs around it have a lot of water inflow.

　　Below the Weibo, "Lang Qibo" is still full of doubts about the reply words of many netizens, and asks for evidence to prove the authenticity, and says that the water pump in the park can be turned off to prove it.

　　"The water pump is mainly used to water the green plants in the scenic spot, and the substation box is mainly used for power supply in the scenic spot." A staff member of the scenic spot said that they also paid attention to the contents of the Weibo, and the water pump that made the netizens doubt was mainly used for watering. In addition, the power distribution room mentioned was the scenic spot substation box, which had nothing to do with the water pump. "The spring eye of Baotu Spring is a natural phenomenon and cannot be moved. Our job is to protect it."

　　Now Jinan, online celebrity is well known by more and more people. Walking around the moat, Black Tiger Spring and other scenic spots, you will find transformer boxes in hidden and safe areas at regular intervals. With the arrival of "Quancheng Night Banquet" in Jinan, these transformer boxes are very useful and add a lot of color to Jinan night scene.
