　　Zhongxin. com, Yanyuan, September 29th (patriotic struggler) by Yan Yimeng.

　　"Far away, Hanshan stone path is oblique, and there are people in the depths of white clouds. Stop and sit in the maple forest late, and the frost leaves are red in February. " On the morning of the 29th, Lang Lang’s reading sound came from Dazu Primary School in Dazu Village, Luguhu Town, Liangshan Prefecture, Sichuan Province. The reporter sought the sound and went to the Mufang classroom with Mosuo traditional residential style. I saw the third-grade students staring at the textbooks intently and reading aloud.

　　Dazu Primary School is a private and complete primary school, with 72 students in seven grades, 80% of whom are Naxi, Mosuo and Yi students. In 2000, due to the shortage of education funds, the school was removed and merged, and in 2004, the whole village was rebuilt under the initiative of Li Nanyang, an old man in Taiwan Province. Today, 15 years later, the classrooms, playgrounds, dormitories, infirmary, library and computer room of Dazu Primary School all witnessed its transformation again and again.

　　Now, talking about the original intention of rebuilding the school again, You Jingfen, a Taiwan Province friend of Li Nanyang and a teacher who has been in charge of Dazu primary school resource integration for 15 years, has a calm and natural tone. She introduced that in 2004, Li Nanyang wanted to come to Lugu Lake to develop eco-agriculture, but unexpectedly saw that so many children could not afford to go to school. "I think that I still have some resources, and these children also have this need, so I feel that I should help them." You Jingfen said that because it coincided with Li Nanyang’s idea, she began to raise funds and work with the villagers to rebuild Dazu Primary School.

　　Wang Muliang, the principal of Dazu Primary School, was one of the villagers who contributed to the reconstruction of the primary school. He recalled that at the beginning of the school’s reconstruction, there were only preschool classes and first grade, and then one grade was added year by year. It was not until 2010 that a complete primary school was built. "At the beginning, we only had two classrooms. Now there is a classroom in each grade, and the area of the school has increased from the initial three or four acres to eight acres." Wang Muliang listed the changes in the school. He said that today the school also offers 11 courses, including English, Dongba and information technology, which broke the previous single curriculum arrangement.

　　"Today, Dazu Primary School is inseparable from the support and help of the government and caring people from all walks of life." Wang Muliang felt that since the school was completed in 2005, thousands of teachers have come to Dazu Primary School for long-term or short-term teaching. At present, there are 13 post-80s and post-90s teachers from all over China.

　　Cui Ning, a 21-year-old girl from Henan, is the youngest teacher in Dazu Primary School. Cui Ning said, "I don’t have much ambition. I am attracted by the local customs here to teach." In Cui Ning’s view, he may not be able to teach children too much knowledge, but it is meaningful to give them some small guidance and care in art, music and other classes.

　　It is understood that Li Nanyang, who initiated the reconstruction of Dazu Primary School, died in 2007. Over the years, teachers who inherited the legacy of the old gentleman have built Dazu Primary School into a campus nourished by culture and love. Wang Muliang, who has worked in Dazu Primary School for 15 years, said that "persistence" is a mission to the development and rejuvenation of villages. You Jingfen, who only goes back to Taiwan Province two or three times a year now, believes that many years of rural education will leave warm "seedlings" in the hearts of students.

　　When the bell rang, 9-year-old Mosuo king of the children ran to the teacher’s office with a textbook. "Xiao Xiao Wu leaves send a cold sound, and the autumn wind on the river moves the guests." Wang Erche Naomar is carrying a small hand, facing the teacher and reciting sentence by sentence what he learned the day before. She said that Chinese is one of her favorite subjects. "My teachers are very gentle and teach books well. When I grow up, I also want to be a Chinese teacher in Dazu Village, so that more people can learn knowledge." (End)

　　Hotspot dialogue

　　During the two sessions of the National People’s Congress, Beijing Youth Daily reporter interviewed Chen Hongbin, deputy to the National People’s Congress and director of the Supervision Office of Yancheng No.1 Primary School.

　　Classroom efficiency has been improved after "double reduction"

　　Beiqing Daily: How many years have you worked in Yancheng No.1 Primary School?

　　Chen Hongbin: I was assigned to work in Yancheng No.1 Primary School in 2001. Since 2009, I have served as the director of the comprehensive department of Yancheng Experimental Primary School, the director of the information center of Yancheng No.1 Primary School Education Group, and now I am the director of the supervision office of Yancheng No.1 Primary School.

　　Beiqing Daily: It has been more than a year since the "double reduction" policy was introduced. What is the current academic status of primary school students?

　　Chen Hongbin: It is definitely different from the situation before the "double reduction".

　　First of all, the burden of off-campus training for students is basically gone. Take Yancheng, where I live, as an example. Through the strict control and governance of our education authorities, there are no cultural extracurricular tutoring institutions now. For children, it really lightens the burden. Secondly, the children’s homework burden is also reduced, and the classroom efficiency is higher.

　　It is suggested that social professionals participate.

　　Beiqing Daily: The "double reduction" policy has achieved the goal of reducing the burden and improving the quality. What are the difficulties at present?

　　Chen Hongbin: After the "double reduction", the workload of teachers has increased, and they may spend up to 10 hours in school every day, which reduces the time for teachers to participate in scientific research, teaching and research activities. Why do teachers spend more time at school? Because of the after-school delay service.

　　In order to better meet the diverse after-school service needs of students, the Ministry of Education has made special arrangements for further improving the after-school service of compulsory education for many times, and promoted the after-school service to be further detailed and practical.

　　Our school is also trying to create such an environment. However, after all, there are still insufficient professional personnel, because there are so many teachers who teach music, physical education, beauty, science and technology. So this time I have a suggestion — — Establishing a long-term and effective guarantee mechanism for social professionals to participate in after-school delay service can enrich the content of students’ after-school delay service, and on the other hand, it can reduce the time burden brought by "double reduction" to teachers to some extent.

　　Beiqing Daily: How did your school solve the above problems?

　　Chen Hongbin: On the one hand, we seek some professionals to enter the campus to participate in after-school delayed service through resources from parents and society. However, this is often a feeling, and the liquidity is relatively large, which brings difficulties to the quality assurance of delayed service.

　　Our school is also strengthening teaching and research activities, especially the teaching and research of homework. For example, we have developed some long-distance homework, and the content of homework is not only around grades, but also to increase children’s practical experience, such as adding small experiments in science and technology, which has expanded students’ practical ability.

　　Delayed service after class needs financial support.

　　Beiqing Daily: How do you think to establish a long-term and effective guarantee mechanism?

　　Chen Hongbin: I think it is necessary to establish a financial guarantee mechanism. If the relevant social workers are allowed to participate in the after-school delayed service for a long time, they need financial resources as a guarantee. According to their workload, it is both recognition and respect for them to pay appropriate labor remuneration.

　　In addition, the human security mechanism should also keep up. At present, most university teachers and professionals participate in the delayed service in their personal capacity, and the original unit has no corresponding support mechanism. In order to let them participate in the after-school delay service in primary and secondary schools for a long time, it is necessary for these units, preferably the higher authorities, to introduce relevant systems, recognize and support their work, and include them in the assessment category, so as to establish a long-term guarantee mechanism.

　　According to the China Seismological Network, at 13: 54 on November 17, an earthquake of magnitude 5.0 occurred in the sea area of Dafeng District, Yancheng City, Jiangsu Province, with a focal depth of 17 kilometers and a epicenter about 45 kilometers away from the coastline.

　　The official WeChat account of Jianjun Road Primary School in Yancheng revealed that the floor was slightly shaken when the earthquake occurred, and all the teachers in the class responded quickly and issued instructions. It took only 3 minutes and 09 seconds for more than 1,600 teachers and students to get from the classroom to the playground.

　　Xu Hongfei, the headmaster, told The Paper (www.thepaper.cn) that he was in his office when the earthquake happened, and all classes were preparing for the first class in the afternoon. After feeling the floor shaking, Xu Hong flew out of the office. "I found that each class was evacuated in an orderly manner under the guidance of the teacher for the first time. It took a little more than 3 minutes, and more than 1,600 teachers and students had been evacuated to the playground." He said.

　　After the evacuation was completed, Xu Hongfei made a few simple remarks to appease the students’ emotions. After a class, teachers and students return to the classroom.

　　According to Xu Hongfei, in recent years, the school has organized an emergency evacuation drill with the participation of all teachers and students every month. The time is not fixed, and it is arranged according to the course situation. The drills mainly simulate emergencies such as earthquakes and fires. For example, in an earthquake, teachers and students are required to hold their heads and evacuate, while in a fire, they should bend over and cover their noses and mouths.

　　Xu Hongfei said that the school had asked the fire department for guidance, and then spontaneously organized evacuation drills and trained teachers, such as how to guide students to evacuate in an orderly manner in case of emergencies.

　　According to the news on the afternoon of 17th of WeChat published by Yancheng Municipal Party Committee Propaganda Department, after preliminary verification, no casualties and property losses caused by the earthquake have been found in coastal towns, parks, enterprises, offshore wind power facilities and fishing boats.

CCTV News:On the 8th local time, US President Trump announced that the United States ranked the Iranian Islamic Revolutionary Guard as a "terrorist organization". This is the first time that the United States has listed a country’s national armed forces as a terrorist organization.

About an hour after the United States announced that Iran’s Islamic Revolutionary Guards were listed as "terrorist organizations", Iran’s Supreme National Security Council announced that the US Central Command and its related military forces were listed as terrorist organizations.

In a statement issued that night, Iran’s Supreme National Security Council strongly condemned the US action, which it considered as "illegal and dangerous". The statement said that the United States and its allies support "extremist and terrorist organizations" in West Asia, and the Iranian Islamic Revolutionary Guard Corps has always been in the front line of "fighting terrorism and extremism" in this region. The United States’ actions are "groundless", flagrantly violating international law and the Charter of the United Nations and threatening regional and even world peace and security. The United States should bear all the responsibilities for "all dangerous consequences" caused by this behavior.

Iranian foreign minister

Before Iran’s Supreme National Security Council issued a formal statement, Iranian Foreign Minister Zarif sent a letter to Iranian President Rouhani, urging Iran to take revenge. Subsequently, Zarif also said on social media that the US action was "a gift to Israeli Prime Minister Benjamin Netanyahu on the eve of the election" and "another dangerous wrong move in this region".

American troops in the Middle East will be regarded as terrorists by Iran.

Iranian Deputy Foreign Minister Alagh Qi stressed in an interview with Iranian state television: From now on, Iran will no longer regard American troops in the Middle East as normal soldiers, but as terrorists, and American military bases will also be regarded as terrorist base camps.

Islamic Revolutionary Guard Corps will face more sanctions.

The United States declared the Iranian Islamic Revolutionary Guard Corps a "terrorist organization", which is the first time that the United States listed the national armed forces of a country as a terrorist organization. According to relevant US procedures, the State Council informed Congress of the decision, and if Congress has no objection within 7 days, the decision will come into effect. According to the relevant regulations of the United States, American financial institutions will freeze the assets of the Iranian Islamic Revolutionary Guard Corps in the United States; Any individual in the United States will be prohibited from providing support to the Iranian Islamic Revolutionary Guard Corps; The United States also banned the entry of Iranian Islamic Revolutionary Guards.

The Wall Street Journal and other mainstream American media quoted people familiar with the White House as saying that there are actually different opinions on this decision within the US government. Pompeo, Secretary of State, and Bolton, National Security Adviser, insisted that the Iranian Islamic Revolutionary Guard Corps should be designated as a terrorist organization, but the military, including the Pentagon, and some security departments were worried that Iran might take revenge.

On September 10th, Extreme Yue 07 was officially launched. Extreme Yue Automobile was jointly built by Geely Group and Baidu Group. Extreme Yue 07 is the second model of the brand, and it is also a medium and large pure electric car. There are three versions of the new car, with a price range of 209.9-299.9 thousand yuan and a limited cash discount of 10,000 yuan.

Mr. Xia’s joke "Extreme Yue 07 is Model 5 that Tesla didn’t make" is just a joke, but it does make it easier for users to understand the positioning of this product. It is a new generation product with larger size and more advanced technology, which pays attention to driving experience and adopts visual intelligent driving scheme.

Extreme Yue 07 canceled the design of the door handle, the radar round hole and wiper were designed in a hidden way, and at the same time, it was equipped with an automatic lifting electric tail, which matched with the diffuser surrounded by blackened bottom, giving a full sense of movement, and at the same time, the wind resistance was 0.198Cd lower, which was at the leading level in the industry.

　　Just after the summer vacation, dozens of parents in a kindergarten in Jiangyin, Jiangsu Province are worried about one thing about their children. According to several parents told The Paper, a teacher in the park was diagnosed with tuberculosis during the summer vacation, and then 28 children and 4 faculty members in the park were found to be infected with tuberculosis, and 5 of them were diagnosed with tuberculosis.

　　Jiangyin City Center for Disease Control and Prevention (hereinafter referred to as CDC) confirmed the above statement to The Paper. Five children diagnosed with tuberculosis are currently out of school and taking therapeutic medication, and 23 children infected with mycobacterium tuberculosis are taking preventive medication.

　　According to Jiangyin’s official introduction, after the relevant epidemic situation was monitored in early July, the functional departments and territories did a lot of work, and experts from provincial and municipal CDC participated in the whole process of support, and repeatedly made face-to-face explanations to parents, accompanying parents to invite the most famous experts in China to consult in Shanghai, and the epidemic situation was handled as quickly, legally and effectively as possible.

　　At present, the kindergarten has screened more than 270 teachers and students in the whole kindergarten. At present, there are no new cases of tuberculosis and the disease has not spread further.

　　28 children were infected, the first mass incident of tuberculosis in kindergarten in Jiangyin.

　　The incident kindergarten is the experimental kindergarten in Zhouzhuang Town, Jiangyin City (Nijiaxiang Branch).

　　According to the director of the park named Sun, The Paper was told that in May and June this year, a teacher in the park, Li Qing (a pseudonym), suffered from throat discomfort and other symptoms. After that, the teacher went to Jiangyin People’s Hospital and Jiangyin Chinese Medicine Hospital for examination on May 26th and June 2nd respectively.

　　"The results of the examination at that time were allergic rhinitis and allergic cough, and no tuberculosis was detected." Sun Yuanchang said.

　　However, the condition is still not good. After the summer vacation this year, the teacher went to Wuxi Second People’s Hospital for examination on July 8 and learned that he had tuberculosis. "The symptoms at that time were serious and hemoptysis." Sun said.

　　Parents know that the above happened on July 15th (Sunday). On the morning of the same day, the class news informed more than 30 teachers and students in the teacher’s class to conduct T-SPOT screening for tuberculosis on July 17th (Tuesday)..

　　Chen Xianwen, director of Jiangyin CDC, told The Paper that in this round of screening, among more than 30 teachers and students in this class, 17 (including 13 students and 4 faculty members) had strong positive results, that is, they had obvious tuberculosis infection, which made them more likely to get sick.

　　On July 20, the CDC organized the 17 people to go to Jiangyin People’s Hospital for further chest X-ray examination. Chen Xianwen said that one child’s chest X-ray was abnormal, that is to say, there was a suspected tuberculosis patient.

　　But parents are not at ease with Jiangyin’s test results. Finally, under the coordination of many parties, on July 26, Jiangyin CDC, Health Planning Commission, Education Bureau and other departments organized the students to go to the Public Health Clinical Center affiliated to Fudan University in Shanghai for inspection. The final conclusion is that among the 17 people, 5 children were diagnosed with tuberculosis.

　　"As soon as we found many cases, we expanded the scope of screening in mid-August and screened more than 270 teachers and students in the kindergarten." Chen Xianwen said that in the end, 15 strong positive cases were found, and there were no new cases of tuberculosis.

　　Now,The 28 infected students are all taking medication. Among them, five students diagnosed with tuberculosis have dropped out of school at home.. Yan Haidong, deputy director of Jiangyin Health Planning Commission, told The Paper,One of the five children is the child of the sick teacher Li Qing..

　　Chen Xianwen said that after investigation, there was an epidemiological correlation between 32 infected people and the initial illness of the sick teacher, that is, the former was infected and the latter spread after the illness.

　　"This is the first tuberculosis group incident in Jiangyin that I have learned about in the past ten years." Chen Xianwen said that no new cases have been found.

　　According to Yan Haidong, the kindergartens involved organize teachers to have a physical examination every year. After passing the physical examination, they will issue a health certificate to the teachers. They checked Li Qing’s medical examination record in August 2017, and "the chest radiograph is normal".

　　Two major questions of parents

　　Although the child has been treated at present, parents still have two big questions.

　　First, they hope that the garden and the Education Bureau will explain why the teacher was not found to be suffering from tuberculosis in time and stop his class in time to prevent the disease from spreading further. Parents believe that the garden and the education department have dereliction of duty in supervision.

　　It is understood that teacher Li Qing is a nursing teacher in the kindergarten, and she usually takes care of the children’s lives most of the time.

　　"Our child coughed one day and the teacher told him to go home and rest, saying that he was afraid of affecting (infecting) other children. Why did the sick teacher cough for several months and wear a mask to attend class, and the garden still let her continue to attend class?" A student’s parents said to The Paper.

　　Xu Qianfeng, director of Jiangyin Education Bureau, told The Paper, "The key is that the teacher’s first two visits were not tuberculosis. Since it is not an infectious disease, there is no reason not to let her attend class. It is normal for a teacher to cough and have an uncomfortable voice in class. "

　　The sick teacher Li Qing (pseudonym) told The Paper that before the diagnosis, she didn’t know that she was suffering from tuberculosis. "What a great experience it is to know that I have an infectious disease and go to work. I also have children." Li Qing said that after the diagnosis in July, she told the kindergarten leaders that she was tuberculosis. Before that, kindergarten leaders sometimes asked her why "cough has been bad" and whether she had seen a doctor.

　　"Teachers and schools don’t know in advance that it is tuberculosis. How can they be held responsible? Punish teachers? Teachers are also victims. " Wang Jian, deputy director of Jiangyin Education Bureau, told The Paper.

　　Parents’ second question is why before going to Shanghai for examination, the screening result organized by Jiangyin CDC was "only one suspected tuberculosis patient", while the result in Shanghai was five cases.

　　After screening in Jiangyin, Jiangyin CDC suggested that students infected with germs can start preventive medication for patients with strong positive, which is different from therapeutic medication for patients diagnosed with tuberculosis. "If you didn’t go to Shanghai for diagnosis, didn’t the five confirmed patients delay the treatment opportunity?" Student’s parents B said to The Paper.

　　In this regard, Chen Xianwen said that the difference in diagnosis results between the two places may come from two reasons. First, "Shanghai is a CT diagnosis, and we take a chest film. There is a difference in the clarity between chest film and CT"; On the other hand, "the two diagnoses are six days apart, and the development of tuberculosis is dynamic, which may also affect the diagnosis results."

　　"We handled it according to the" Code for Prevention and Control of Tuberculosis in Schools (2017 Edition) ",and the above requirement is to take a chest X-ray. However, Shanghai’s medical technology and concept are more advanced. They use more accurate and advanced CT. We have reported the inconsistent diagnosis results caused by the two diagnostic methods to the (Jiangsu) Provincial Health Planning Commission. " Yan Haidong, deputy director of Jiangyin Health Planning Commission, told The Paper.

　　CDC: Tuberculosis is treatable.

　　Parents reported that at present, the children’s medical expenses are paid in advance by parents and later reimbursed by the government.

　　In addition to asking kindergartens to take responsibility, another issue that parents are concerned about is whether children can be cured and whether it will affect their future study and work.

　　Chen Xianwen said that after years of medical development, tuberculosis is currently preventable, controllable and treatable. For patients with strong positive, the incubation period of bacteria is generally six months. As long as they are properly treated and recuperated during this period, they can recover slowly. For patients diagnosed with tuberculosis, the general treatment period also takes half a year. "From the tuberculosis cases we have contacted before, the recovery rate is over 90%." Chen Xianwen said.He also said that cure does not mean never recurrence, and not paying attention to physical maintenance will increase the chance of tuberculosis recurrence.

　　Chen Xianwen also said that the impact of tuberculosis on studies and work is limited to the period of illness. "If you just had tuberculosis, the employer won’t refuse to hire you. If you are suffering from tuberculosis at the time of applying, it will not work. " Chen Xianwen said that people are afraid of tuberculosis because they are afraid of infection, but if it is cured, it will not have an impact.

　　What’s more, "statistics show that at present, 40% of Chinese people are infected with mycobacterium tuberculosis, but some of them are hidden and have not yet developed." Chen Xianwen said to The Paper.

　　However, parents’ concerns remain. It is reported that after the tuberculosis group incident, the enrollment rate of the kindergarten in the new semester was greatly affected. Wang Jian, deputy director of Jiangyin Education Bureau, saw from the data on September 5 that,At present, there are only more than 100 students enrolled in the park, which is nearly half of the number compared with last semester. Many parents transfer their children to other kindergartens..

　　Even, "a teacher transferred to another school and was boycotted by the parents of that school." Parents of students said to The Paper.

　　At the same time, some parents reported that Li Qing’s illness may have been infected by previous tuberculosis cases in her village and town. "It seems that (the patient) lives opposite Li Qing’s house."

　　In this regard, Li Qing told The Paper that she was unclear. "The doctor just told me that I didn’t know where I was infected before, and then my body’s resistance dropped, and I often got sick after staying up late and not resting enough."

　　Yan Haidong, deputy director of Jiangyin Health Planning Commission, said that the tuberculosis patient from Li Qing’s hometown was diagnosed with tuberculosis in January this year, but there is not enough evidence to verify whether there is a correlation between the two diseases. "It is understood that this person is not a close contact of Li Qing". "Because tuberculosis is mostly transmitted through the respiratory tract, Li Qing has a wide range of activities and many contacts, so it is temporarily impossible to verify where she was infected."

　　Cao, deputy director of Jiangyin CDC, told The Paper that at present, there is a unified online monitoring system for tuberculosis in China, and the CDC has special personnel to check the detection system every day. As long as a case of tuberculosis is found, it will begin to follow up its medical treatment.

　　The system especially focuses on monitoring key places such as schools. "If there are cases in schools, the system will automatically send relevant messages to the mobile phones of disease control personnel." Cao said.

　　Take Li Qing’s illness as an example."After she was treated in Wuxi on July 8, the doctor entered this case into the monitoring system. However, she did not indicate that she was a teacher at that time, so she was treated as an ordinary tuberculosis case." Yan Haidong said.

　　succedentOn July 12, Li Qing went to Jiangyin People’s Hospital to get medicine. "When the hospital medical staff asked about the illness, they asked about their occupation. After knowing that she was a teacher, they updated this information to the monitoring system and reported it to the competent department., our CDC staff also found in the monitoring system, and then organized school screening. "Cao said to The Paper.

　　"Now the country is very strict in the prevention and control of infectious diseases. If there are cases that are missed, the punishment is very severe." Cao said. (The Paper reporter Chen Ke intern Wan Xiaotian)

　　On October 27, 2017, the International Agency for Research on Cancer under the World Health Organization compiled and published a list of four types of carcinogens according to their relevance to cancer. Class 1 is a definite carcinogen for human beings; Type 2 is limited evidence of carcinogenicity to humans; Category 3 is suspicious of human carcinogenicity; Category 4 is substances that may not be carcinogenic to human body.

　　There are 120 kinds of class 1 carcinogens, including alcoholic beverages, Chinese salted fish, processed meat, air pollution, solar radiation and smoking, which are closely related to people’s daily life. Chief reporter Lin Bibo

　　China news agency, Beijing, October 4 (Reporter Ruan Yulin) Li Ganjie, Minister of Environmental Protection of China, stressed during his investigation in Beijing, Tianjin and Hebei and surrounding areas during the 11th National Day that since the beginning of this year, the air quality in some places has fluctuated, and the improvement rate of air quality has obviously slowed down or even rebounded, making it very difficult to complete the set goals and tasks for the whole year. It is necessary to strengthen environmental law enforcement supervision and promote the effectiveness of various measures to prevent and control air pollution.

　　The Ministry of Environmental Protection announced on the 4th that Li Ganjie led a team to Hebei, Shanxi, Shandong, Henan and other places for investigation from October 1st to 3rd. Bulk coal combustion has become an important factor affecting the quality of atmospheric environment in northern China in winter, and it is also a weak area in the current air pollution control in China.

　　Li Ganjie pointed out that it is urgent to solve the problem of bulk coal heating. We must adhere to the principle of replacing coal with gas, replacing coal with electricity and replacing high-quality coal simultaneously, and continue to promote it according to the principle of adapting measures to local conditions, implementing it step by step and taking multiple measures simultaneously.

　　To promote Beijing-Tianjin-Hebei and surrounding areas in 2017— In the comprehensive control of air pollution in autumn and winter of 2018, Li Ganjie proposed to maintain a high-pressure situation and strengthen environmental law enforcement and supervision. Since the beginning of this year, the air quality situation in some places has fluctuated, and the improvement of air quality has slowed down obviously, or even rebounded. It is very difficult to complete the set goals and tasks for the whole year. It is necessary to strengthen environmental law enforcement and supervision, urge all localities to increase environmental governance, and promote the effectiveness of various measures to prevent and control air pollution.

　　At the same time, it is necessary to strictly quantify the assessment accountability and promote the pressure transmission in place. Conscientiously implement the "five-step method" of supervision, assignment, inspection, interview and special inspection, fully complete all the objectives and tasks of "Atmosphere Ten", and resolutely fight the blue sky defense.
