　　Nowadays, fitness has become a fashion, but many people are busy with work and have no time, which leads to the delay of courses. Can I return my fitness card after I get it? In the past few days, the reporter learned that the biggest headache for consumers is that once they want to return their cards halfway, they will often be rejected by merchants for various reasons. In this regard, a number of gymnasiums replied that gymnasiums have regulations that fitness cards cannot be returned. If citizens have special circumstances, they can transfer their cards to others, but they need to charge a certain handling fee.

　　The public reported that the coach who changed frequently in private classes wanted to return the fitness card but was rejected.

　　Ms. Zhang, a citizen, told the reporter that in October 2017, she met the coach of a fitness club near Nanning Zoo through purchasing, and agreed to buy private lessons at the price of 300 yuan/Festival. Subsequently, she transferred 2,000 yuan as a course deposit through WeChat. After that, because Ms. Zhang’s company started her initial business, she was very busy at work and never had time to go to the gym. In April 2019, the coach told her that if she didn’t make up the final payment, the previous deposit would be invalid according to the company’s regulations. At the end of April, she went to the gym to make up the final payment. According to the coach, she bought 12 private lessons for a period.

　　After Ms. Zhang attended the first class, the coach said that her leg muscles were tense and she needed to buy stretching courses to train better. To this end, Ms. Zhang purchased five more stretching courses. Unexpectedly, just halfway through the first stretching class, the coach said something was wrong and asked another female coach to continue the class. After four stretching classes, the female coach was informed that there was a change in her work, so she could not continue to teach Ms. Zhang and was docked with another coach to teach her.

　　At the end of June, before the private education course was finished, the coach said that the course was offered a discount. At the suggestion of the coach, Ms. Zhang bought 15 private lessons at a price of 4050 yuan.

　　After that, because of the company’s many things, Ms. Zhang has not been able to insist on finishing the private teaching class. During the National Day holiday, the coach informed Ms. Zhang that she still had nine classes, and if she didn’t go to class at the end of the month, the courses would expire. Therefore, Ms. Zhang found time to attend classes in the fitness club. As a result, she only had a class. The coach also said that she could not continue to serve Ms. Zhang because of job changes.

　　"I changed six coaches in a row, which greatly affected the fitness experience. Other coaches simply don’t know my training progress and adaptation intensity, and the effect of temporary classes can be imagined. " In addition, it is suspected that the fitness club has the behavior of inducing consumption, so that Ms. Zhang insists on returning the card. On October 12th, Manager Qin of the fitness club told Ms. Zhang that the results could only be given after consulting the company. Two days later, manager Qin replied that according to the company’s regulations, the fitness card could not be returned and the gym continued to serve her.

　　The gym said: the fitness card will be invalid when it expires, and there will be a fee for returning the card and transferring it.

　　If the consumer fails to finish the private teaching course for some reason, the course will expire and become invalid? Manager Qin of the fitness club said that according to the company’s system, exercisers can take two months off for a one-year card, which means an extension of two months, and a two-year card can take four months off.

　　"After members purchase the course, they begin to follow the process. The coach should make a fitness plan according to the members’ physical condition and personal needs, and make preliminary, medium and late arrangements." Manager Qin said that if the company wants to operate normally, it also needs rules and regulations to regulate it. At that time, Ms. Zhang bought regular classes to reduce fat, gain muscle and shape. Once the contract was signed, it was agreed according to the contract, and the fitness card could not be returned. If you can’t continue to exercise for personal reasons, the club can apply to the company for Ms. Zhang to transfer her card to her relatives and friends, but a certain handling fee is required to transfer the card, and both parties have to go to the fitness club to issue a certificate and an agreement to transfer classes. Or they apply to the company to transfer Ms. Zhang to other stores in the company to facilitate Ms. Zhang’s fitness.

　　Regarding Ms. Zhang’s reflection on the frequent change of coaches in private lessons, Manager Qin said that Ms. Zhang bought the private lessons of the company, not the courses of the coaches who docked with her at the beginning. "There is really no way about the turnover of people. The turnover of people in the fitness industry is relatively frequent, and we can’t stop the coaches from leaving."

　　Then, what is the agreement of this fitness club on the membership card in other gymnasiums? Is it a general rule in the industry? During the visit, Xiao Zou, a staff member of a fitness center in Changchun Road, told the reporter that fitness is not compulsory consumption. If citizens do not pay the final payment for a long time after paying the deposit, they will basically not cancel the subscription after the expiration. After the card is issued, there will be a card opening time. Whether you go to the gym or not, it will be expired after it expires.

　　Coach Zhang of a fitness center in Ming Xiu East Road said that after ordinary citizens buy annual cards, the number of times they exercise is not limited, but it will be automatically invalidated as soon as the time comes.

　　The reporter visited and found that many gymnasiums have the regulation that fitness cards are "once sold, they will not be returned". When a gym signs a contract with a consumer, it will indicate in the contract that if it wants to transfer or return the card, it needs to pay a certain fee. For example, buying a 2-year fitness card costs 2,000 yuan, while returning or transferring the card costs 300 yuan or even more. The shorter the card is, the higher the fee charged for card return and card transfer. In this regard, many gym staff said it was the company’s regulations, because the fitness card was issued by real-name registration system, and if you want to transfer the card, you need to re-do the system.

　　Impulse consumption: many people spend money on cards and have no perseverance to keep fit.

　　During the visit, many citizens said that it was a temporary fever to run a fitness card. Maybe I feel fat, or I am envious when I read a chicken soup article about fitness and see someone else’s vest line. I got a fitness card on the spur of the moment without a fitness plan and I am not sure whether I can stick to it.

　　After getting a fitness card, many people can’t stick to fitness. For example, Ms. Wei, a citizen, heard that a gym in Taoyuan Road had preferential activities, and the two-year card was only 1380 yuan, so she went to get a card. She thought that fitness was nothing more than running, lifting iron and push-ups, but when she came to the gym, she looked at the equipment and didn’t know its name, so she was a little at a loss. Moreover, she didn’t know how to exercise and what kind of training plan she was suitable for, and with no one to accompany her to exercise, Miss Wei gave up. Two years later, in order to motivate herself to fall in love with sports, she got a card in another newly opened gym. Then, due to tight working hours, going to the movies, eating delicious food and other reasons, the fitness went away, and the membership card for two years only went several times.

　　Mr. Luo, a citizen, said that because he was too fat and disliked by people around him, he made up his mind to develop abdominal muscles. So, he held a private education class in a gym on Hengyang Road. According to the agreement, Mr. Luo should buy private lessons at every stage of fitness. In the meantime, because he couldn’t bear the intensity of exercise, he gave up fitness after only a few classes.

　　Consumer reminder

　　Pay attention to restrictive regulations when handling cards.

　　Don’t rush to spend money and get a large card.

　　Can citizens return their cards if they don’t go to the gym for a long time after getting them? Is it reasonable to pay a handling fee to the gym for card transfer? In this regard, Zhao Mingtang, a lawyer of Guangxi Guanghe Law Firm, said that the gym refused to return the card, which is a market behavior. In terms of contract disputes, gyms and consumers are equal subjects. Whether the card can be returned mainly depends on whether there is inducement or fraud when the gym handles the card for consumers. If there is such behavior, consumers can ask the gym to return their cards; Otherwise, we must abide by the provisions of the contract agreement.

　　Sign a written agreement

　　Lawyer Zhao Mingtang reminds everyone that when applying for the annual fitness card, it is best to sign a written agreement with the merchant on whether to charge for returning or transferring the card, and learn more about the contents of the agreement.

　　The staff of 12315 suggested that consumers should pay attention to the fitness card, and must sign a written agreement with the merchants, especially pay attention to the restrictive provisions, and don’t be confused by the preferential conditions of the operators. In the complaints about the consumption of fitness prepaid cards accepted by the market supervision bureau, most merchants do not sign any form of contracts, but only verbally agree. Once disputes arise, consumers’ rights and interests cannot be guaranteed. Therefore, before signing a written contract, consumers should read all the terms carefully and be aware of them. At the same time, the other party is required to stamp the official seal and ask the operator for invoices or receipts in case of consumer disputes.

　　It should also be noted that there is not much difference in the probability of problems with fitness cards between chain stores and non-chain stores. Consumers should not easily believe that chain stores are more reliable. If a chain store claims that it can be used in multiple chain stores when handling the card, consumers can check with other chain stores on the spot and write the commitment into the supplementary agreement.

　　Try to avoid handling large fitness cards.

　　To apply for a fitness card, you should fully consider your own actual situation, such as your physical condition, hobbies, fitness time, etc., and don’t believe in the promotion of the fitness shop for a while and blindly consume. (Reporter Wei Wei)

　　Yesterday, the 2019 Beijing College Entrance Examination Marking Media Open Day was held. Beijing Youth Daily reporter learned from the scene that in 2019, Beijing will continue to implement online marking for all subjects of the college entrance examination. There are 6 marking points for the college entrance examination in the city, and a total of 1,173 teachers will take part in marking this year’s college entrance examination, and a total of about 200,000 papers will be required. According to the work arrangement, marking began on June 9th, and it is expected to end on 22nd. Candidates’ college entrance examination results will be released at 12 o’clock on 23rd, and the lowest scores of college entrance examination batches (types) and statistics of scores of college entrance examination results will also be announced to the public on the same day.

　　From 8: 00 on June 25 to 20: 00 on June 29, the candidates for the unified examination will fill in the undergraduate pre-approval volunteers, special types of enrollment volunteers, and undergraduate general approval volunteers, while the candidates for the single examination will fill in the vocational education teacher class and the single examination volunteers for higher vocational education. Candidates must log on to the website of Beijing Education Examinations Institute (www.bjeea.edu.cn; Www.bjeea.cn) volunteered to fill in the report, and completed the information submission before the deadline for filling in the report, and will not make up the report after the deadline. Once the time for volunteering is closed, no one may change it.

　　Go through the "Sandao Pass" when entering the marking point.

　　"Back-to-back double evaluation" of all test papers

　　On the afternoon of June 14th, the reporter of Beiqing Daily saw at the marking site of Tsinghua University college entrance examination mathematics subjects that at least the "Sandao Pass" was required to enter the marking point: first, security personnel were responsible for the inspection at the entrance, and irrelevant personnel were not allowed to enter; Secondly, to enter the marking point, you need to provide valid documents, hand in your backpack and electronic communication equipment such as mobile phones; Thirdly, there is also a "double security check" measure at the marking point. In and out, not only the security check door, but also the staff holding the security check instrument for secondary inspection.

　　According to reports, this year’s marking sites will continue to be closed. At the same time, the network connection is physically separated from the external network in the form of local area network to prevent virus infection and hacker intrusion; In addition, the server storing the data information of the answer sheet is placed in a special computer room, and the key marking places are equipped with video monitoring and recording equipment, and the video monitoring is all-round and there is no dead angle; Backup management and remote storage of marking database. Report the illegal papers, identical papers or abnormal situations with political problems found in the marking process in a timely manner. Questions with different scores shall be discussed collectively by the subject working group, and the treatment scheme shall be determined after reaching an agreement. All subjects are subject to "back-to-back double evaluation", and if the double evaluation exceeds the threshold, three or four evaluations will be conducted.

　　There are more than twenty hurdles to get full marks in mathematics.

　　The most difficult finale question has been given full marks.

　　According to Yu Xiaoxiao, director of the Admissions Office of Tsinghua University, there are about 280 marking teachers in this year’s math marking point, 60.7% of whom are from Tsinghua University, and the rest are teaching and research personnel from various districts and backbone teachers in middle schools. Except for 40 multiple-choice questions, which are graded by the machine, the remaining 110 points are graded at the math marking point.

　　According to the quality expert group, the mathematics examination questions in Beijing are more open this year. For example, the content of the 17th question is probability statistics, and the answer is not unique. Candidates can score as long as they cover the knowledge points of the examination, which is rare in the past. For many parents and candidates who are worried about "whether the process is right but the result is wrong", the quality expert group explained that if the process is right but the calculation is wrong, not only can you score, but you can lose a few points and get most points.

　　Yu Xiaoxiao introduced that in addition to the final comprehensive spot check, the mathematics marking of the college entrance examination will also be spot-checked during the marking process, such as the papers with 0 points or full marks for each topic, the papers with too high or too low scores, and the papers with large double scores. Group leaders, group leaders and expert groups must all check 100%. Judging from the current marking situation, some students have got full marks for the most difficult grand finale, but the marking is not over yet, and the scores of all topics have not been added up, so the full marks are still unclear.

　　However, Yu Xiaoxiao said that from the procedural point of view, in order to get full marks in mathematics, in addition to getting full marks in 40 multiple-choice questions, the solution questions must pass at least 20 passes: first, each question of the solution questions must be randomly "back to back" at least through "double evaluation" and the score meets the requirements; After that, the test paper leader with perfect score for each topic should be 100% rechecked; In addition, all the papers with a total of 110 points will be reviewed by the expert group.

　　At present, there has been a perfect composition in Chinese.

　　The ratio of candidates writing argumentative essays and narratives is 7:1.

　　Song Yayun, deputy director of the Chinese Department of Peking University, said that there were 330 reviewers of Beijing Chinese volumes this year, 10 more than last year. The whole set of Chinese test questions embodies the implementation of moral education, examination of Chinese literacy, emphasis on subject situation design, highlighting the examination of candidates’ thinking ability, further paying attention to learning process and methods, guiding candidates to observe life, think positively and pay attention to application. At the same time, the structure of this year’s Chinese test paper in Beijing College Entrance Examination is the same as before, the types of questions are basically stable, and there are some new changes. The length of the test paper is reduced, the number of words is slightly reduced, and the number of questions is reduced, which reflects the "burden reduction in taking the exam".

　　Song Yayun introduced that in this year’s college entrance examination, the big composition of Beijing Chinese volume was either argumentative essay "the resilience of civilization" or narrative essay "the color of 2019", and the proportion of candidates who chose argumentative essay and narrative essay was about 7:1. At present, the big composition has been given full marks. "Today is the third day of positive evaluation," Song Yayun introduced. The full marks of the composition are accurate in topic review, accurate in structure, full in argumentation, beautiful in language, etc. Both narrative and argumentative essays have full marks. At the same time, he also mentioned that failing to answer the composition will be regarded as a zero-point composition.

In the real estate market, blank houses attract many buyers with their unique charm. It gives buyers more independent space to build their ideal homes, but it is not easy to buy a blank house that meets their own needs, and the purchase decision will be affected by many factors.

First of all, being clear about your own needs is the key. In terms of housing demand, if the family population is large, it is necessary to consider large-sized units to ensure that every family member has enough living space; For singles or newlyweds, a small apartment may be more suitable, which can not only meet the living needs, but also reduce the cost of buying a house. The purchase budget also plays a decisive role, which directly limits the range of available houses. If the budget is limited, we need to pay attention to some areas or buildings with relatively low prices; If the budget is sufficient, there can be more high-quality houses to choose from.

Location and supporting facilities are also factors that cannot be ignored. A rough house with a good location often has higher appreciation potential and living convenience. The convenience of surrounding traffic is very important. Being close to subway stations, bus stations or main roads can greatly shorten commuting time. Commercial facilities also affect the convenience of daily life. There are large shopping malls, supermarkets and vegetable markets nearby, which can meet various life needs such as shopping and catering. Educational resources are also the focus of many property buyers, especially families with children. Quality schools can provide a good educational environment for children. Medical support is equally important, so that you can get medical treatment in time when you are sick.

The quality of real estate and the reputation of developers also have great influence on the purchase decision. Housing quality is the foundation of living, and high-quality building quality can ensure the safety and comfort of living. You can understand the quality of the house by looking at the building materials, construction technology and word-of-mouth of past projects. The reputation of developers is also very critical. Developers with good reputation usually pay more attention to project quality and after-sales service, which can make buyers feel more at ease.

In order to compare the influence of different factors on the purchase decision more clearly, the following is a simple table:

Market conditions, policies and regulations will also affect the purchase decision. When the real estate market is on the rise, it may be necessary to make a purchase decision as soon as possible to prevent the house price from continuing to rise; In the downturn of the market, you can have more time and choice space. Changes in policies and regulations will also have a major impact on the purchase of houses, such as restrictions on purchases and loans, which will directly affect the purchase qualifications and loan quotas of buyers.

When buying a blank house, you need to conduct a field trip. Check the apartment structure of the house on the spot, understand the lighting and ventilation of each room, and feel whether the spatial layout of the house is reasonable. At the same time, it is necessary to check the quality of the house to see whether the wall is flat, whether there are cracks, and whether the ground is level.

Buying a blank house that meets the demand requires comprehensive consideration of many factors. Property buyers should be clear about their own needs, pay attention to lots and facilities, attach importance to the quality of real estate and the reputation of developers, understand market conditions, policies and regulations, and conduct on-the-spot investigations, so as to make wise purchase decisions.

△ Sunbathing, planting plants and reading books are the most comfortable life for Gou Jun.

At night, sleeping on the sleepers of the old railway, listening to the rumble of the small train but not noisy, making a cup of tea and telling stories in Chongqing. This is the dream life of many people, but in an old house hidden in the city in the triangle road of Huangjueping, all these may come true.

Gou Jun, an old Chongqing enthusiast, has traveled all over the world and collected more than 5,000 maps in the past 30 years, and then spent two months to build a "Xanadu" for himself-Junge Bookstore, where you can read local chronicles from all walks of life and enjoy Chongqing in different periods on maps. With luck, I can meet a group of old Chongqing fans at the courtyard dam in front of the door and listen to their stories about old Chongqing.

On the 25th, the upstream journalist came to the Junge Bookstore located in the triangle road of the fourth village of Huangjueping Railway, bringing you Gou Jun and his "old Chongqing" world.

△ Gou Jun sorted out the map that he just found.

Old map attached to tourism

Speaking of the fate with maps and local chronicles, Gou Jun was obsessed with reading Geography Knowledge magazine (the predecessor of chinese national geography magazine) when he was a child, but he really started to collect books, but it was a journey at the age of 21.

In 1988, Gou Jun was already a "donkey friend". At that time, he rode a bike from Chongqing to Leshan, and the local customs and geographical beauty along the way made him linger.

"I just want to do something to keep this memory." So Gou Jun bought a "Leshan Tourism Traffic Map", "not only can you find tourism information, but you can also keep it as a commemorative collection, which has both practical value and collection value."

Originally, Gou Jun had been collecting stamps and magnetic cards, but after that, he fell in love with collecting maps. When he first started, he just bought some tourist maps, and then gradually began to buy administrative maps.

With the passage of time, the administrative map can’t satisfy Gou Jun’s hobby of collecting. He found that many old maps with the flavor of the times were drawn by hand and with a brush, which is not only artistic, but also more detailed. "When you touch these old maps, you can feel the taste of the years. Time brings us temperature and memory, and every old map is a work of art."

△ Gou Jun spends a lot of time reading books every day.

More than 5,000 maps and 5,000 books in 30 years

"This is the Atlas of Fengdu County, this is the book Sleepless on the North Shore, and this is the Collection of Studies on the Inheritance of National Culture …" In Junge Bookstore, Gou Jun showed his books to upstream journalists one by one, but the books and maps placed in the bookstore are just the tip of the iceberg. His home is the "golden house". Most of the books and maps collected from all over the country in the past 30 years are.

"Look! If you buy more than one book, you can pile it up! " Looking at a room full of books and maps, Gou Jun’s parents often complain that there are more than 5,000 maps and nearly 5,000 books in a room, and the walls, floors, tables and chairs are all piled up or not. He will only sleep on the sofa if he frees up his bed to pile up books. "I don’t feel annoyed when I sleep in this kind of book, but I sleep more soundly."

Gou Jun told the upstream journalists that in the past five years, he spent nearly 100,000 yuan on books every year, and spent 10,000 yuan every month when he was more. When he was less, he had to "remove" more than 7,000 books and maps.

△ There are various maps hanging on the wall in the bookstore.

Rebuild the old house by hand in two months to build the old Chongqing cultural living room.

Because there are more and more books and maps in the collection, it is inconvenient for friends to visit, and even it is inconvenient to take their feet after entering the house, so Gou Jun wants to find an independent space to store his "baby".

At the end of 2017, a friend subletted an old bungalow in the triangle road of the four villages of Huangjueping Railway to Gou Jun. As soon as he saw this blue brick house at the junction of the railway, he fell in love with it-the house has a big courtyard dam, and a few meters in front of the door is the intersection of the three railways, hence the name "triangle road". Every night after ten o’clock, there will be a small train rumbling past the house, which is very charming but not noisy. From time to time, nearby residents will pass by carrying the vegetables they just bought, or the smell of fried bacon from next door will waft in. "This kind of life picture is in line with my memory of’ old Chongqing’, and this is the independent space I have been preparing for a long time."

△ The postcard designed by Gou Jun is created with the scene behind him.

Gou Jun found an art friend, and the two of them took over the old and messy old house and started the road of design. Friends are responsible for design, while Gou Jun walks around the streets, collecting unwanted and unusual old objects and furniture and decorating the bookstore.

At the beginning of March, it took Gou Jun only two months to complete the renovation of his old house. The signboard of "Junge Bookstore" was carved by him, the bookshelf was designed by himself, and every decoration was randomly placed according to his hobbies. Gou Jun brought some books and maps at home to the bookstore, where fans can read books and buy whatever they like.

If you are lucky, choose a sunny afternoon to come to Junge Bookstore. You can also see the old streets in Chongqing and cultural lovers sitting on the courtyard dam at the entrance of the bookstore, each holding an old teacup to talk about the land and telling stories about Chongqing.

△ The signs in the bookstore are all made by Gou Jun.

His feelings of selling books: the national book lovers are paying more and more attention to Chongqing.

"In 10 years, Chongqing has developed and changed rapidly, and loving the motherland begins with loving your hometown." In the past, Gou Jun paid little attention to books and maps in Chongqing, but in the past 10 years, he has paid more and more attention to the collection of local chronicles and maps in his hometown, and he wants to be a witness to the development of Chongqing.

Gou Jun also has his own shop on Confucius Old Books Network, selling surplus old books and old maps. He has an intuitive feeling: "I personally feel that in recent years, book lovers all over the country have paid more and more attention to books related to Chongqing, which reflects the growing charm of Chongqing, and more and more people are willing to pay attention to Chongqing and understand Chongqing culture."

In the future, the "Junge Bookstore" will be officially opened to tourists and enthusiasts. Gou Jun wants to gradually build the bookstore into an old Chongqing cultural living room, so that every friend who loves old Chongqing and likes reading books can feel a sense of belonging here, can talk and laugh, and can find his connection with the city in the book. "Drinking tea and selling books, Chongqing Salon, I hope that the future’ Junge Bookstore’ will be more free and energetic."

　　Our reporter Guo Wei Weasion Wei

　　August is the hottest season of the year in Fujian, and the "ozone prevention and control" being carried out throughout the province is also very hot.

　　Take the lead in issuing ozone prevention and control guidelines, promote 120 provincial key emission reduction projects, and consolidate the foundation of pollution control and emission reduction … … Fujian started with the top-level design, played a combination boxing, treated the ozone with the right medicine, and made the blue sky defense war develop in a scientific and refined direction.

　　Strengthening the top-level design and paying attention to both the symptoms and the root causes

　　Fujian’s air quality has been excellent for a long time, ranking in the forefront of the country, and the overall ozone concentration has remained excellent, which is better than the national average. Why should we keep an eye on ozone? "You can’t take it lightly, or be lucky. You must plan ahead, make precise policies, and grasp ozone prevention and control like smog control." The relevant person in charge of the Fujian Provincial Environmental Protection Department said frankly.

　　The person in charge’s worries are not excessive. From 2014 to 2016, the average specific percentile concentrations of ozone in Fujian Province were 115&mu respectively; g/m3、111μ g/m3、115μ G/m3, which is generally excellent, is better than the national average. However, in 2017, under the effective control of PM2.5, due to adverse meteorological conditions and other factors, the ozone concentration in Fujian Province increased significantly, especially from April to November, which was a high-value period of ozone concentration in Fujian Province and became a prominent factor dragging down air quality.

　　Fujian Province is soberly aware that at present, ozone pollution control in various places is not strong enough, measures are not in place, the level of waste gas collection and treatment of VOCs-related enterprises is still low, and unorganized emissions are serious. At the same time, there are a certain number of "scattered pollution" enterprises in various places, with backward production technology and simple pollution control facilities, which are also important factors causing atmospheric environmental pollution.

　　The "Guidelines for the Prevention and Control of Ozone Pollution in Fujian Province (Trial)" was first issued in China. According to the characteristics of climate, topography and industrial structure in various places, it emphasized local conditions and the right medicine, and put forward the requirements of refined management in the whole process from source prevention, process control to terminal treatment.

　　Twelve departments, including Fujian Provincial Environmental Protection Department, National Development and Reform Commission, and Economic and Information Committee, jointly issued the Work Plan for Ozone Pollution Prevention and Control in Fujian Province, establishing and improving the working mechanism of ozone pollution prevention and control with clear responsibilities, division of labor and joint management, and proposing to establish and improve the ozone pollution prevention and control management system with improving ambient air quality as the core by 2020, and strive to reduce the total emission of VOCs by more than 10%.

　　In order to fill the shortcomings of the emission standards for volatile organic compounds (VOCs) of ozone precursors, Fujian Province has formulated three mandatory local standards for VOCs emission standards for printing industry, industrial painting process and industrial enterprises, which have been agreed by the provincial government and will be issued and implemented in the near future.

　　At the same time, Fujian Province has also listed ozone remediation as the focus of the "three-in-one" inspectors, namely, the feedback from the central environmental protection inspectors, the feedback from the provincial environmental protection inspectors and the inspection and notification of the responsibility book of the party and government leaders for ecological environmental protection. The problems of poor promotion, serious lag in the progress of rectification, superficial rectification, pretend rectification and perfunctory rectification are held accountable according to laws and regulations, and the responsibility of local party committees and governments for ozone pollution prevention and control is consolidated.

　　Implement 120 key emission reduction projects to promote precise governance.

　　Enterprises with large VOCs emissions such as petroleum, chemical industry, painting and shoemaking in Fujian Province, and enterprises with large NOx emissions such as thermal power (including thermal power and self-provided power stations), steel and flat glass are mainly concentrated in coastal areas, which is also an area with serious ozone pollution in Fujian Province.

　　Targeted prevention and treatment, the right medicine. All parts of Fujian Province cooperate to control VOCs and NOx for key pollution sources, focus on key industries and key enterprises, and promote ozone prevention and control to be precise, accurate and practical.

　　"Up to now, 50 precision management projects have been completed, and the emission reduction ratio has been 38%." Pointing to the schedule of atmospheric environmental precise control and emission reduction projects, the person in charge of the Atmospheric Department of Fujian Provincial Environmental Protection Department said that on the basis of reports from various places, the Provincial Environmental Protection Department screened out 120 provincial-level key precise control and emission reduction projects, and implemented regular scheduling, notification, early warning, supervision, interviews and other systems. According to preliminary statistics, these key projects can reduce VOCs emissions by nearly 10,000 tons and NOx emissions by more than 3,000 tons annually.

　　Fujian Province has also carried out intensive supervision of key areas in the province, strengthened law enforcement inspection of waste gas emission enterprises in key areas such as Zhangzhou City, Quanzhou City and Putian City, and created a strong offensive and high-pressure situation of law enforcement supervision. More than 2,000 enterprises involved in VOCs emission were inspected, and corporate environmental violations were severely investigated according to laws and regulations.

　　All localities closely follow the actual situation and implement rectification of key industries.

　　Fuzhou has optimized its industrial layout and prohibited the introduction of projects with serious pollution. Comprehensive treatment of VOCs in chemical, pharmaceutical, synthetic leather and other industries in Jiangyin Industrial Zone of Fuqing and Minhou Automobile City; Deepen the rectification of the iron and steel industry around Luoyuan Bay and reduce NOx emissions.

　　Xiamen has implemented rectification in stages by industry, and has started the third stage of rectification of four industries: shipbuilding and maintenance, rubber products, shoemaking and handicrafts.

　　Quanzhou has strict access to new reconstruction and expansion projects, and VOCs emissions are replaced by the same amount or times. At the same time, it will promote the treatment of VOCs in key industries such as petrochemical industry, industrial painting, packaging and printing, shoemaking, textile printing and dyeing, further improve the LDAR (LDAR) level of Quangang and Quanhui Petrochemical Park, and promote the environmental protection upgrading and transformation of industrial pot kilns.

　　Putian deepens the VOCs management of key industries such as shoe-making, packaging and printing, coatings, rubber, chemical fiber and furniture in urban areas; Promote environmental protection upgrades such as industrial boilers and kilns, and reduce NOx emissions.

　　Since mid-July, Zhangzhou has taken the standardized management of VOCs-related furniture enterprises as a breakthrough, enforced the law with an iron fist, promoted the closed operation of VOCs-related workshops of furniture enterprises to realize the complete collection and treatment of organic waste gas, regularly replaced waste activated carbon, and strictly implemented the standardized temporary storage and disposal of waste paint barrels, waste paint residue, waste activated carbon and other hazardous wastes.

　　Ningde focuses on prevention and control in Zhangwan area, and strengthens VOCs treatment in key industries such as battery manufacturing, industrial painting, packaging and printing in Zhangwan Industrial Zone to ensure the stable operation of treatment facilities; Promote waste incineration power generation, steel environmental protection upgrading, and reduce VOCs and NOx emissions.

On May 15th, 2021, the Tianwen-1 lander landed in the southern part of the Utopia Plain of Mars. "Steady!" Jiang Mingjing, who stood in front of the TV, saw the news and stood up from his chair excitedly, holding his fist and cheering.

This report three months ago gave the reporter the idea of interviewing Professor Jiang Mingjing from the School of Architecture and Engineering of Tianjin University. During these three months, the reporter contacted him many times. As a result, Professor Jiang was either on a business trip or on his way. The background of several calls was the voice of the plane broadcast urging him to turn off his mobile phone. Professor Jiang’s busyness made reporters both surprised and helpless, and even had the idea of giving up the interview. Finally, these days, Professor Jiang returned to Tianjin to tutor graduate students, and the reporter seized this "hard-won" opportunity.

According to the report, in order to make Tianwen-1 land smoothly, Jiang Mingjing and his team spent two years simulating the construction of a Mars surface in Huailai County, Hebei Province. Mars, which is tens of millions of kilometers away from the earth, is an unknown field that needs to be explored urgently. It sounds impossible to "move" it to the earth, but Jiang Mingjing succeeded.

"My major is studying’ soil’, and all kinds of’ difficult soil’, such as Mars’ soil, are actually only a small part of my research content." Jiang Mingjing, a native of Jiangsu Province, speaks an authentic "soft language of Wu Nong". It never occurred to him that the tenderness and delicacy of the water towns in the south of the Yangtze River cultivated such a "hard-core" professor who was willing to deal with clods and stones.

"I studied undergraduate in 1982 and have been engaged in geotechnical research for more than 30 years." Looking at Jiang Mingjing’s resume alone, there are nearly one page: Professor, Doctoral Supervisor, Department of Civil Engineering, School of Architecture and Engineering, Tianjin University; bachelor’s degree and master’s degree in engineering from Hohai University in 1986 and 1993, and doctor’s degree in engineering from nanjing hydraulic research institute in 1996. In 1998, he was a special researcher at Osaka Institute of Soil Testing (now Japan Institute of Regional Site Environment); in 1998-2000, he was a special researcher at Kyoto University in Japan; in 2000-2003, he was a postdoctoral fellow at Lavalle University; in 2003-2004, he was a postdoctoral fellow at the University of Nottingham in the United Kingdom; in 2004-2006, he was a professor at Tongji University School of Civil Engineering. Since 2018, he has been a professor and vice president of the School of Civil Engineering of Tianjin University. Since 2010, he has served as the vice chairman of TC105 Committee of the International Association of Soil Mechanics and Geotechnical Engineering (reelected), won the National Natural Science Outstanding Youth Fund in 2009, and was selected into the National Million Talents Project in 2014. The 22nd Huang Wenxi Lecturer, a highly cited scholar in China published by Elsevier (2019 and 2020), and a top 2% scientist in the world published by Stanford University (2020). Experts from the Advisory Committee of the Ministry of Industry and Materials of the National Natural Science Foundation, experts from the Water Conservancy Association, experts from the National Natural Science Award, and young and middle-aged experts who have made outstanding contributions to the country.Enjoy the special post of the State Council government …

There is no need to say anything about the difficulty and gold content of a doctor more than 30 years ago. "At that time, the scientific research conditions were really bad, but the overall academic atmosphere was very positive. Everyone was engaged in research and everything was for scientific research." Jiang Mingjing said that he was lucky to meet a group of good teachers, which not only pointed out the direction for him, but also paved the way for his future scientific research. "When I was studying for a master’s degree, my teacher applied for an exam-free PhD and advanced placement for me, which was unprecedented. At that time, it was the only one in our school." During Jiang Mingjing’s Ph.D. study, the personal research funds totaled only 6,000 yuan in three years. "Although the price was low at that time, it was still far from enough. The teacher took out his funds from the National Natural Science Foundation and made a special application for me. A total of 45,000 yuan was spent on my research projects."

Shoulder the heavy responsibility and live up to expectations. It used to be a worldwide problem to simulate large voids in structural soil. Through analysis, Jiang Mingjing thinks that adding ice particles into soil materials at low temperature can artificially form large voids, and finally the structural soil can be artificially prepared. For this reason, he made a detailed experimental design, which was quickly recognized by the teacher. Although the idea is good, where can we find such a low temperature environment? Until Jiang Mingjing saw the cold storage in the school canteen. "I told the teacher that I have found a way to do the experiment, but I have to trouble you to say hello to the school logistics department."

I heard that Dr. Jiang was going to do the experiment, and the logistics readily "gave the green light". Nanjing in midsummer is as hot as fire, just like Jiang Mingjing’s mood of looking forward to the experiment. "In order to do a good job in the experiment, we made all kinds of preparations as comprehensively as possible, such as equipment, cotton trousers, cotton-padded jacket … that day, we were all very excited, but we were dumbfounded as soon as we entered." The young student was ready for the experiment, but forgot to be mentally prepared-the cold storage belongs to the canteen, and all kinds of "animals" are completely frozen inside. "It’s funny to think of it now, but at that time, several classmates and I were scared to have nightmares at night."

The cold storage experiment was successful, and Jiang Mingjing pursued the victory. "As long as I am engaged in scientific research, I will always be full of combat effectiveness." In order to get the data as soon as possible, he kept his hands on the experimental equipment. The air compressor was used in the experiment, which was very loud, especially in the dead of night. "I am used to it myself, that is, I suffered the residents nearby. At first, some people reported to the director. Later, when everyone knew that they were doing the experiment, they all expressed their support and understanding. I am very moved by it in retrospect."

Thick accumulation can make thin hair. Jiang Mingjing’s research achievements have attracted wide attention in the world. He has not yet graduated from a doctor, and many world-renowned universities have sent him warm invitations. At the beginning of 1998, he went abroad and worked as a postdoctoral researcher in Osaka Soil Experimental Institute, Kyoto University, Lavalle University, Manchester University and Nottingham University. In 2006, with the belief of serving the motherland, he resolutely returned to Tongji University to teach.

During the interview, the reporter always had a feeling that scientific research was not a career for Jiang Mingjing, but a belief, a belief engraved in his bones and willing to follow him all his life. Like, love, obsession … These are not enough to describe his persistence in scientific research. "When I first returned to China, the salary I got a month was only 1,500 yuan, and the rent was 1,850 yuan. For a long time, I was supplemented by my previous savings."

The firm belief has brought Jiang Mingjing to this day step by step, and time has proved it best. In recent years, with the continuous strengthening of China’s comprehensive strength, the scientific and technological strength is also making rapid progress. Aerospace, deep-sea exploration … These sophisticated fields have left more and more China and China footprints. During this period, Jiang Mingjing and his team also undertook project research in many related fields. "In addition to the Martian soil just mentioned, the deep-sea soil is also the focus of our research in recent years. Recently, we are preparing to carry out exploration, development and environmental protection of combustible ice and other resources in Hainan. "

Adhere to the problem-oriented and face the major needs of the country. As an expert and scholar in the field, Jiang Mingjing is well aware of our current shortcomings and weaknesses. "Some key technologies, important equipment, new energy technologies and other fields that are related to the urgent needs and long-term needs of the country must be in our own hands, so we must speed up the pace and work hard in this direction."

From Jiang Mingjing’s words, the reporter can strongly feel his urgent and expectant mood. From a grain of sand to a piece of soil, from a mountain to a star, Jiang Mingjing has always closely linked scientific research with actual needs. Knowing the heavy responsibilities, but having the courage not to be afraid of failure; I also know that the road is far, and I still have the enthusiasm to concentrate on research.

At the end of the interview, the reporter asked Professor Jiang if he expected to visit space in the future. The professor smiled and said, "Of course! Space travel has been realized, which is not far from us. " Only after the hardships of being down-to-earth can we have the courage to look up at the stars. Similarly, we also expect Professor Jiang Mingjing to lead us to see a higher and further world with his scientific research achievements.

Reporter: Can you briefly introduce your research field?

Jiang Mingjing: My research field is soil mechanics, which is an applied discipline to study the stress-strain or stress-strain-time relationship and strength of soil under the action of force. It is a branch of engineering mechanics. The research object of soil mechanics is soil and soil closely related to human activities, including artificial soil and natural soil, and groundwater closely related to the mechanical properties of soil. Soil mechanics is widely used in the design of foundations, retaining walls, geotechnical structures and dams, and is an important branch of engineering disciplines such as civil engineering, geotechnical engineering, engineering geology and energy engineering.

The development of soil mechanics should be initiated by Coulomb, which can be roughly divided into three historical stages: germination period (1773-1923), classical period (1923-1963) and modern soil mechanics (1963-present). Modern soil mechanics is a system based on macroscopic test results, continuum mechanics method and macroscopic constitutive theory of soil, and numerical analysis methods such as finite element and finite difference are used as tools, which plays an important role in geotechnical engineering practice.

At present, with the continuous expansion of geotechnical engineering in space, especially the promotion of deep, deep-sea and deep-space engineering ("three-deep engineering"), researchers and engineers need to face more complex environmental conditions (high geostress, high/low temperature, high water pressure, high vacuum, low gravity, strengthening chemical action, etc.) and difficult geotechnical materials, such as structural soil (temperature, pressure and force coupling, T-

Reporter: After successfully completing the Mars exploration project, what is your current research focus?

Jiang Mingjing: Recently, I am mainly engaged in deep-sea engineering projects. With the rapid development of China’s coastal economy, the proposal of the "Belt and Road Initiative" and the promulgation of the "Thirteenth Five-Year Plan" for the development of the national marine economy, offshore engineering projects such as offshore wind power, cross-sea bridges, submarine tunnels, offshore oil drilling platforms, seawater power generation, submarine pipeline laying, land reclamation and marine nuclear energy are constantly increasing, and offshore engineering projects are constantly growing and enriching. Ocean engineering has changed from traditional engineering projects to new engineering projects, and gradually developed from offshore and shallow sea to far sea and deep sea. The scale of the projects is also expanding, which puts forward higher requirements for the sensitivity, safety and durability of ocean engineering. A series of marine resources development is accompanied by many engineering and technical problems that need to be solved urgently, such as the safety of mining platforms and submarine optical cables, and the early warning and mitigation of natural disasters such as submarine earthquakes and seabed landslides are also the core issues of global concern.

Taking the exploitation of deep-sea natural gas hydrate resources as an example, the decomposition of hydrate will inevitably lead to the deterioration of the mechanical properties of the seabed, and improper exploitation methods may induce large-scale disasters (such as landslides) or the collapse of pile foundation platforms. How to choose a safe mining mode and area to reduce the impact of mining activities on the marine environment has become the primary problem in the actual hydrate mining process. It is very difficult to conduct on-the-spot investigation and research on the seabed, and it is expensive to simulate the deep-sea environment by laboratory tests. Therefore, we need to strengthen scientific research and comprehensively analyze the promotion of marine engineering to ensure its safety and feasibility.

Reporter: After listening to your introduction, we probably know the practical application of soil mechanics. What are your professional opinions on the future development opportunities in this field?

Jiang Mingjing: A new key field of soil mechanics has emerged-macro-micro soil mechanics. In the past 40 years, macro-micro soil mechanics has experienced germination, embryonic form and growth period, so it can be said that it is now welcoming the stage of accelerated development. I think the development opportunities of macro and micro soil mechanics in the future mainly include the following four aspects.

The first is to establish an efficient calculation method suitable for various geotechnical engineering problems. The research in this field may involve the physical and mechanical mechanism on the molecular or nanometer scale, and it also needs efficient coupling calculation methods. Because hundreds of millions or even trillions of particles need to be calculated, this will require high computing power. With the rapid development of computer technology, this contradiction will gradually weaken.

Secondly, according to the real working environment, the model of the difficult rock and soil mass of the "Three Deep Projects" and the relationship between the structural evolution and the macro-characteristics are established. The research in this field not only needs the micro-and micro-scale experimental technology to simulate extreme environments such as high/low temperature, high water pressure, high vacuum and chemistry, but also needs to solve the contradiction between the scale effect of representative units and the limitation of experimental testing accuracy, and also needs to develop the extraction, processing and analysis technology of micro-and micro-structural information in three-dimensional soil. However, with the development of multifunctional, high-precision and large-range X-ray CT, these problems are expected to be solved step by step.

The third is to establish a practical theoretical model, and solve all kinds of complex and difficult core problems in geotechnical mechanics and engineering of "three deep projects" to help improve the engineering design level. In different geotechnical engineering problems, the stress path experienced by soil is different, so it is difficult to accurately obtain the stress path and mechanical properties of undisturbed soil in the field by current geotechnical testing technology. Therefore, it is a research idea to establish a practical constitutive model by using appropriate methods for simulation and corresponding indoor experimental research.

Fourth, the four branches of macro-micro soil mechanics and modern soil mechanics and the cross-development of other disciplines. Macro-micro soil mechanics can not only cross theoretical soil mechanics, computational soil mechanics, experimental soil mechanics and applied soil mechanics in this discipline, but also cross other disciplines, such as rock mechanics and near-field dynamics in mechanics disciplines. This will not only contribute to the self-development of macro-micro soil mechanics, improve modern soil mechanics, but also promote the rapid development of other disciplines.

In a word, macro-micro soil mechanics has become one of the most dynamic research directions, and its accelerated development period is coming soon. To this end, we need the participation of many young scholars with solid foundation and prime of life, as well as the care and support of senior researchers who have been fighting in the front line of scientific research for a long time and have a deep understanding of difficult and key problems in geotechnical engineering.
