The thirty-sixth rectification item specified in the "Rectification Plan for Implementing the Second Round of Central Ecological Environmental Protection Inspector’s Report in Jiangsu Province" has been rectified. According to the "Measures for the Rectification of Ecological Environmental Protection Inspectors in Jiangsu Province" and other documents, the completion of the rectification of this problem is now publicized as follows:

I. Rectification matters

The water quality decreased obviously in flood season. In Huai ‘an, a large amount of sewage and garbage accumulate in the upstream of drainage pumping stations and culverts, and flow into the river with rainwater in flood season, which seriously affects the water quality in the downstream of the basin. In the flood season of 2020 and 2021, the water quality of six important rivers and lakes such as Zhangfuhe, Tangxianghe and Baima Lake decreased significantly. In July 2021, the proportion of excellent water quality sections in the 11 national examination sections in the city was only 27.3%, down 9.1 percentage points year-on-year, and the water quality of four rivers, including Nanliutang River, fell to worse than Grade V..

Second, the responsible unit

Huai ‘an Municipal Party Committee and Municipal Government.

Third, the acceptance unit

The Provincial Department of Ecology and Environment takes the lead, and the Provincial Department of Housing and Urban-Rural Development, the Provincial Department of Water Resources and the Provincial Department of Agriculture and Rural Affairs cooperate.

Fourth, the goal of rectification

The annual average water quality of six rivers and lakes, such as Zhangfuhe, Tangxianghe and Baima Lake, reached the standard; The water quality of Shensanwei of Nanliutang River, the lake entrance sluice of Zhaogong River, Wangmupai Bridge of Wangmupai River and the north Hongsuzui of the drainage channel increased year-on-year, and the average water quality in flood season was eliminated.

V. Time limit for rectification

Before the end of December 2022.

VI. Rectification measures

(a) to carry out the flood season, the water quality is easy to decline in the upper reaches of the national and provincial examination sections, drainage pumping stations and culverts to intercept and store sewage. Organize comprehensive investigation and water quality monitoring of pumping stations and culverts in key areas to form a list of drainage pumping stations and culverts; Organize and carry out rectification with the focus on Class V and inferior Class V water bodies, promptly assign existing problems and urge rectification; During the special drought period in flood season, priority should be given to ensuring agricultural and domestic water; In the case of difficult ecological water supply, we will organize special supervision and assistance for water quality assurance in flood season sections, effectively prevent large fluctuations in water quality in flood season according to local conditions, and ensure water quality in key sections in flood season.

(2) Strengthening agricultural pollution control. Focus on doing a good job of straw leaving the field in key areas, and increase the storage and utilization of straw leaving the field in water-sensitive areas such as Hongjin, Shensanwei, Yubing River and Beihong, the seawater inlet; Carry out the consolidation and promotion of livestock and poultry manure resource utilization, and promote the supporting construction of manure treatment facilities in large-scale farms; Combined with the construction of high-standard farmland projects, we will carry out pilot projects for ecological transformation of farmland irrigation and drainage systems in agriculture-related counties.

(5) Strengthen encrypted monitoring and emergency response in flood season. Pay close attention to the rain and flood, and carry out encrypted monitoring of water quality in key sections. Strengthen the early warning of water quality, so as to find, dispose and eliminate problems early, and effectively prevent the decline of water environment quality. Strengthen the emergency duty of key rivers and sections such as Zhaogong River and Yubing River, which are prone to decline in water quality in flood season, find environmental hazards that may lead to a sharp decline in water quality in sections, start the response at the first time, and take effective measures to properly dispose of them.

VII. Completion of rectification

At present, various rectification measures have been put in place and the rectification objectives have been completed. In the month of July 2022, 11 national examination sections reached or were better than Class III sections, accounting for 45.5%, up 18.2 percentage points year-on-year; 57 countries and provinces accounted for 75.4% of the test sections reaching or better than Class III sections, up 15.8 percentage points year-on-year, ranking first in five cities in northern Jiangsu. During the flood season (June-September), the average water quality of the four sections of Nanliutang River, Shensanwei, Zhaogonghe Lake Entrance Sluice, Wangmupai River Wangmupai Bridge, and North Hongsuzui Drainage Channel were Class III, Class IV, Class III and Class III, respectively. In the same period of 2021, the water quality of the sections was Class IV, Class V, Class IV and Class IV, respectively, and the water quality of the sections was higher than that of 2021. The water quality of six sections, including Shunhe Bridge in Zhangfu River, Houying Bridge in Tangxiang River, Hongjin in Baima Lake, Tangcao in Xunhe River, Shensanwei in Nanliutang River and Wangmupai Bridge in Wangmupai River, all reached the standard. The details are as follows:

(a) the water quality is easy to decline in flood season, and the development of the special action for the upstream drainage pumping station and culvert to intercept and store sewage in the national and provincial examination section. Formulate and implement a special action plan for the renovation of drainage pumping stations and culverts in the city. Before the end of May when the flood season (June-September) comes, the water quality of pumping stations and culverts included in the renovation scope will be completely eliminated. Formulate and issue the city’s water environment protection work plan in flood season, promote the improvement of water environment quality in flood season, and give consideration to ecological water protection while fully protecting urban and rural residents’ life and industrial and agricultural production water. Carry out special supervision and assistance for water quality assurance of key sections in flood season to ensure water quality of key sections in flood season.

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.

(Editor Liu Xiaoyan Han Jingfeng)

　　"Yellow croaker wants it?"

　　"What’s the price?"

　　"There are three big 120 yuan and one extra-large 80 yuan."

　　On the afternoon of May 6th, at the export commodities fair in the B2 central hall of the global port in Putuo District, Shanghai, an old couple who were just about to go to the "Pearl of the Sea" cinema upstairs passed by and didn’t miss it. They directly paid for three large yellow croakers, and told the boss that they hoped to keep them for them, and they would come back after watching the movie at six o’clock in the afternoon.

　　"No problem, we will give you a good ticket. I will pick it up by ticket later. " Yao Mei, general manager of Shanghai Guoxin Aquatic Products Sales Department, wrapped the three fish selected by the old couple in a thermal insulation bag and put them in the freezer. According to Yao Mei, this large yellow croaker was not for retail before, but only for hotels and exports. Because the United States wants to impose tariffs on global trading partners, the company simply moved the large yellow croaker to the exhibition. "It’s a work announcement, and I feel that consumers are willing to pay for these goods!" .

　　From the Ibera women’s shoes in Qingpu to the thermos cups of Shimizu Daily Products Co., Ltd., anyway, this fair has accelerated the work of the relevant staff-it originally ended in mid-May, but since May 13, it has been transferred from the B2 Central Hall to the South Square of the shopping mall. The reason is that the statistics of Global Harbor show that more than 100,000 orders were sold in the B2 floor trade fair area in 21 days, and the momentum of the transaction has not weakened, but there is still a tendency to enlarge.

　　From April 18th, the "Shanghai E-commerce Matchmaking Meeting to Help Foreign Trade Expand Domestic Sales" to April 28th, the "Shanghai Shopping Mall Excellent Foreign Trade Matchmaking Activity" was held, with one meeting and one activity, which promoted the "face-to-face" communication between key shopping malls and supermarkets in Shanghai and nearly 80 foreign trade enterprises, and connected many domestic demand channels. Looking around the big picture, the internal and external environment is still changing. On May 10th and 11th, local time, China and the United States held high-level economic and trade talks in Geneva, Switzerland, and reached a series of important consensuses. On May 12, China and the United States issued a joint statement on the Geneva economic and trade talks, jointly revised or cancelled relevant tariffs, and established a mechanism to continue consultations on economic and trade relations. How to adapt to the environment at the fastest speed? The reporter observed that some foreign trade enterprises, including Shanghai, seized the "window period" and entered the "catch-up mode", and simultaneously deepened the expansion of non-American markets and accelerated the global layout with the strategy of "multi-line advancement".

　　In an interview with Xinmin Weekly, Chen Zilei, a professor at the School of International Business and Economics of Shanghai University of International Business and Economics, analyzed: "In the face of changes in the external environment, China’s trade needs to pay attention to two points. First, it is necessary to "open up", for example, through the "Belt and Road Initiative" to realize the diversification of exports, open up markets around the world, including the global South, emerging economies, or developing countries, and increase the trade share in this area; Second, to integrate domestic and foreign trade, it is necessary to build a unified national market, improve the mobility of factors and break the domestic market barriers. That is to say, the policy of expanding domestic demand is well implemented. In this way, we can transform some high-quality products that were originally exported into our expansion of domestic demand. "

Which hot items to turn back to?

　　During the May Day holiday, there were more than 20 foreign trade enterprises participating in the exhibition in B2 Central Hall of Global Harbor, covering some shoes, hats, bags and aquatic products. By May 13th, when the Global Harbor Export Commodities Fair was moved to the south square of the shopping mall, not only the number of exhibitors increased to more than 50, but also products such as home appliances were added. As far as food is concerned, there are some that continue to sell well, and some that are newly added and sell well.

　　Pseudosciaena crocea is a "star" that continues to sell well. Yao Mei said that in the 21 days in B2 Central Hall, more than 5 tons of yellow croaker were sold, which was 20% higher than the company’s annual export in 2024! After the trade fair was moved to Global Gangnan Plaza, consumers still wanted to buy large yellow croaker. However, due to the hot weather, in the semi-open environment, how to supply consumers with well-preserved goods after freezing has slightly tested the docking ability between Guoxin Aquatic Products Sales Department and Global Port. Fortunately, the storage, pick-up and transfer of these goods are all minor problems. All parties can join hands to supplement the freezer, which can completely ensure the good quality when they reach the consumer terminal. Some citizens said: "I bought honey, yellow croaker, coffee beans and slippers, totaling more than 1,000 yuan to support domestic products." Some citizens also said: "The price is more affordable and the quality of foreign trade is more assured."

On May 10th, the "Global Port Export Commodities Fair" was held on the B2 floor of Global Port.

　　Business is really good. "On May 13th, the first day of the transfer to South Square, less than 10 o’clock in the morning, many citizens gathered at the entrance of the trade fair to wait for admission. At 11 o’clock in the morning, some foreign trade commodity counters in the venue have been sold out. " Maidan, assistant general manager of Shanghai Global Port, said. The reporter passed by the global port fair several times and found that the main consumers were middle-aged and elderly customers. According to these aunts and uncles, because people have retired, they have leisure to pick up goods during the day on the working day in the middle of the week, and in the impression, the quality of China’s export commodities is guaranteed anyway. "When Lao Diji heard that there was an export to domestic sales, he knew,’ Don’t be too embarrassed’, just buy it!" Some aunts said so.

　　In Yong ‘an Department Store on Nanjing East Road, there is a slightly different scene from the global port. On May 6, in the corner of the third floor of Yongan Department Store, a customer stopped in front of a jeans booth that had not appeared here before. A friend said that he "had never heard of this brand before". Another friend said that when he went to the United States a few years ago, he saw this brand in a large outlet store in New Jersey, and it sold well in the local market. The salesperson also confirmed: "This is a brand originally exported to the United States, and the quality is very good." The English logo of the American brand was made into a KT board, and it was also marked "Export to Domestic Sales". A Shanghai aunt stepped forward and pinched her jeans. "Well, it feels good!" She said to the man accompanying her, ready to try it on in the fitting room. From this aunt’s body, it is obvious that since she was young, she naturally has a sense of smell for fashion and trends, and quickly captures them. And this brand, which just came into the market in Yongan Company in the name of "export to domestic market", although it only sells women’s jeans for the time being, has withstood the eye test of some Shanghai women with rich life experience, and has a good sales volume-more than 20 pieces were sold in one morning, even if the absolute value is not high, but it has reached a brand-new "two-way trip". After all, a few years ago, if you wanted to buy this brand of jeans, you had to find someone to buy them in the United States-a pair of pants made in China but not sold in China. The buyer of this pair of trousers is in China.However, the trousers have to travel across the ocean to the United States-even to the outlets on the east coast of the United States, and then they are packed into bags and returned to China by plane with the purchasers. Even so, at that time, the price was cheaper than domestic similar goods, and the quality was better than domestic similar goods. Nowadays, from the factory to the fans in China, this pair of jeans no longer needs to fly back and forth in the Pacific Ocean, and the price also makes consumers feel comfortable.

On the first floor of the first food store on Nanjing Road Pedestrian Street, there are nearly 30 kinds of foreign trade goods exported to domestic market on the newly renovated "Silede" counter.

　　In such a situation of "export to domestic sales", merchants certainly actively cooperate. Chen Hui, manager of tenant management department of Yongan Department Store, said, "Under normal circumstances, it takes at least one month for a new brand to go online. If the brand is settled in according to our joint marketing model, it should be decorated by itself, and everything should be prepared by itself, but this time we will do it for you, the hangers are supported by various counters, and even the salespersons are rotated by employees in various positions in the mall. " According to the on-site salesperson, "extraordinary operation" and "green channel" make the newly imported goods transferred to Yong ‘an Department Store be sold on the counter at a faster speed.

　　As the reporter saw in the pedestrian street of Nanjing East Road, some export-oriented counters have to face the competition of online commodity sales. On May 6th, a coffee pot with a price of 288 yuan attracted the interest of an old man in front of the counter of the export brand "Silede" on the first floor of a food store. After playing with it for a while, he asked the selling price of this coffee pot in the American market. The shop assistant politely replied, "Uncle, I don’t know." A young man at the scene immediately compared the online selling price and told the old man that "during the May 5th Shopping Festival, he can get another discount from 200 yuan to 20 yuan", which seems quite cost-effective. The old man felt tempted.

　　In Chen Zilei’s view, the export of some consumer goods to domestic sales can bring certain benefits to the development of domestic economy and people’s livelihood. "Export to domestic sales can serve to expand domestic demand." Chen Zilei told reporters, "In the future, if there are more products that can improve consumers’ quality of life on the domestic market, this is not a bad thing. Can contribute to meeting the people’s growing needs for a better life. I think, at the same time, we have to increase imports to enhance the overall consumption vitality. "

Build a complete domestic demand system

　　Some media observed: "The transformation of’ export to domestic sales’ jointly promoted by policies, enterprises and consumers is not only a self-help of foreign trade enterprises, but also an upgrading experiment related to the quality of life of every ordinary person. The shift of export products to domestic sales has brought new pressure. The original domestic products must compete with the low-cost export-grade inventory on the same shelf. " However, some people think that this kind of friction will definitely force the original domestic products: from "OEM" to "quality awakening", and stimulate the domestic retail industry to become more efficient, diversified and competitive. This is an opportunity to turn pressure into motivation, and it is a subversion.

　　Zhang Juan, deputy director and researcher of Shanghai Open Strategy Research Center (Shanghai WTO Affairs Consulting Center), said that there is a set of data that can’t be ignored: according to the export volume and domestic commodity sales of foreign-funded enterprises, the domestic sales scale of foreign-funded enterprises in China is about twice that of their exports in China. This data is even higher for foreign-funded enterprises in Shanghai. "Since China joined the World Trade Organization (WTO), foreign-funded enterprises have always been the mainstay of China’s foreign trade." Zhang Juan analyzed, "The proportion of goods exports of foreign-funded enterprises in Shanghai’s total exports reached a historical peak in 2010, about 70%; It fell to about 48% in 2024. In 2003, the domestic commodity sales of foreign-funded enterprises in Shanghai were only 0.46 times of the foreign-funded enterprises’ exports. In 2009, the domestic commodity sales of foreign-funded enterprises in Shanghai exceeded their exports for the first time, and in 2023, it was 6.8 times of the exports. This shows that foreign-funded enterprises are increasingly considering China’s ultra-large-scale market advantages when investing in China. "

　　In the early 1970s, at the beginning of Sino-US contact, the United States was in the midst of an oil crisis, and the Bretton Woods system, that is, the international monetary system centered on the US dollar, disintegrated. How does the United States rescue? From Kissinger’s secret visit to President Nixon’s visit to China: Politically, the United States naturally has the intention of wooing China to jointly fight against the Soviet Union; Considering the economy, the international trade system and even the financial field, to a great extent, the United States at that time also hoped to explore China, a country with a vast territory and a large population. Although China’s productivity was not high at that time, it already had a relatively complete national economic system. Shortly after the reform and opening up, the success of many Sino-foreign joint ventures, Sino-foreign cooperation and wholly foreign-owned enterprises proved that China’s relatively complete national economic system and good basic education can provide a highly competitive labor force. While making "foreign-funded enterprises" make full profits, it also makes the China market develop gradually. In the 1980s and 1990s, and at the beginning of this century, with the changes of the world trade pattern and the ups and downs of the market, China also experienced several climaxes of "export to domestic sales". It was also a beautiful thing for consumers to buy domestic products with export quality. Zhang Juan believes that at least since Trump took office for the first time, the pattern of international trade has gradually changed. "During the first term of the Trump administration, the trade pattern began to accelerate to localization, inshore and friendship. However, China’s domestic market cannot be ignored. This time, the United States imposed "reciprocal tariffs" on global trading partners, regardless of the outcome afterwards.Or how the modality evolves, in short, it will prompt more and more foreign-funded enterprises to change from "‘in China for world’" (from China to the world) to "‘in China for China’" (from China to China) and pay more attention to the contribution of China market to enterprise growth. "

　　Zhang Juan believes that, from a deeper level, the export of foreign-funded enterprises to domestic sales is not only the internal transfer of the consumer market, but also the internal transfer of the production supply chain, that is, not only to sell more end products in the China market, but also to comply with the supporting requirements of the supply chain developed by local enterprises in China, and to participate in China’s domestic supply chain system, from parts import to localized production.

May 12: The Sino-US joint tariff statement boosted market sentiment, and the Nasdaq closed up 4.35%.

　　Professor school of economics and management of Tongji University and Chen Qiang, executive director of Shanghai Industrial Innovation Ecosystem Research Center, told reporters that in recent years, some people in the United States and the West have been urging and drumming up, which has intensified the "decoupling and breaking the chain", making the global competition in science and technology and industry increasingly severe. "If a country’s innovation system and industrial system can be deeply integrated into the world and closely interact with the supply side and demand side of the high-level global market, then there will be opportunities to obtain elements and energy supplies from the outside and release energy to the outside, thus continuously improving the overall efficiency of the system." Chen Qiang said, "However, the situation has changed due to’ decoupling and chain breaking’. How should we deal with it? On the one hand, we should promote the construction of modern industrial system through scientific and technological innovation and industrial innovation, so as to further enhance the technological content, cost advantage and brand value of "Made in China" and form a stronger international market competitiveness. On the other hand, we should also take precautions, make ideological preparations and work preparations to deal with the uncertainty of the external environment, give full play to Socialism with Chinese characteristics’s institutional advantages and the advantages of huge domestic demand market capacity and rich levels, enhance the resilience of the domestic demand system, and absorb the various shocks brought about by changes in international political and economic patterns. "

　　After the Sino-American meeting in Geneva, the tariffs were adjusted, which seems to be a relief. However, recently, many shopping malls in Shanghai and even many cities across the country have successively opened up foreign trade excellent products zones, and some media reports have called them "stopgap measures to long-term strategies". But we also have to see that for a large part of exporters, the way forward will need to find new markets or turn to domestic sales. The commodities involved are mainly consumer-oriented household goods, clothing and electronic products, rather than industrial parts. In the short term, this is not a supply chain problem, but a sales system problem. Chen Qiang once pointed out that "building a new development pattern with the domestic big cycle as the main body and the domestic and international double cycles promoting each other is a strategic choice made by the CPC Central Committee according to the changes in the domestic and international situation. To speed up the construction of a complete domestic demand system, it is necessary to promote scientific and technological innovation and other aspects of innovation." From this perspective, export and domestic sales are also components of "building a complete domestic demand system".

Reshape the world trade pattern

　　In the short term, it seems that some products that were originally exported are currently put into the domestic market. With the slight achievements in the relevant tariff negotiations between China and the United States, some enterprises have accelerated their export production; In the medium term, changes in tariff negotiations between China and the United States, as well as between China and the world’s major economies, can lead to changes in the production objectives of enterprises; In the long run, will the United States impose so-called "reciprocal tariffs" on all its trading partners, forcing countries to take various actions and eventually reshape the world trade pattern?

　　As the vice president of the National Japan Economic Association and the president of the Shanghai Japan Society, Chen Zilei has specially studied the past of Japan-US trade friction and its long-term impact on the Japanese economy. "After the trade friction between Japan and the United States, Japan had to promote economic operation through two links. First, export control; Second, increase imports. However, Japan’s self-regulation of exports to the United States, in particular, actually inhibited the production vitality of Japanese enterprises. Looking back, it is not conducive to industrial upgrading, to ensuring employment, and to the development of enterprises. " Chen Zilei analyzed, "Japan is not doing well in expanding imports to the United States. On the one hand, there were great differences between American goods and Japanese market demand at that time. This problem has never been well solved. " In Chen Zilei’s view, the only bright spot of what Japan did in those years was to transfer the industrial chain overseas through production transfer, open up the trade chain through the third-party market, enter the American market, and even move the factory to the United States, where it is now produced and sold. In this respect, there is no lack of learning from others.

　　Professor Chen Qiang observed that in recent years, the technological capability of China’s manufacturing industry has been continuously enhanced, the industrial foundation has been continuously consolidated, the management level has been rapidly improved, and the characteristics of high-tech content and high added value of export products have become more and more obvious. According to the data released by the General Administration of Customs, in 2024, the export volume of automobiles in China reached 6.41 million, a year-on-year increase of 23%. Exports also increased significantly, reaching $117.4 billion. "In addition, China’s product competitiveness in the fields of network communication, new energy, high-speed rail, nuclear power and construction machinery has gradually increased, and tangible progress has been made in quantum technology and artificial intelligence." Chen Qiang analyzed, "In the new export pattern, different countries and regions have different demands for China products, with different scales, structures and levels. From this point of view, the connotation of "export to domestic sales" is different, and developed countries have higher requirements for the quality and technical content of products. The significance of China’s increasing exports lies in maintaining interaction with the higher-level demand side, and taking this opportunity to continuously enhance the technology and management capabilities of China manufacturing. If it is sold domestically, it can also meet the higher-level needs of the domestic market. Developing countries are more sensitive to the cost performance of their products. China Manufacturing should increase its exports to them by virtue of its technological advantages and cost control ability, and exchange technology for the market. Even if the situation changes, the market space for domestic sales is relatively large. " In essence, due to the huge economic volume of China, it is not just a few large yellow croakers, but the reshaping of the international trade pattern that will eventually be instigated by the "export to domestic sales".

　　China news agency, Beijing, February 9 (Reporter Ruan Yulin) The Ministry of Environmental Protection of China informed the media on the evening of the 9th that a systematic dusty weather process occurred in China, which affected Inner Mongolia, Gansu, Ningxia, Shaanxi, Shanxi, Hebei and other places, and the hourly concentration of inhalable particulate matter (PM10) rose sharply, with the hourly concentration of PM10 in Zhangye City, Gansu Province exceeding 3,600 micrograms per cubic meter.

　　Influenced by the gale weather, a systematic sandstorm weather process occurred from north to south in China from noon on February 8. The sand was mainly located in southern Mongolia, central and western Inner Mongolia, China and western Gansu.

　　In the first five months, the total retail sales of social consumer goods reached 13.87 trillion yuan, and the decline narrowed. In May, the sales of heavy and light trucks both reached record highs in the same period. From January to May, the total planned investment of new projects increased by 7.9%… … A series of figures show that China’s domestic demand is accelerating.

　　At present, a series of policies and measures around "six stabilities" and "six guarantees" are gradually taking effect, and the resumption of business and markets in various places is accelerating, especially under the impetus of multiple measures such as expanding domestic demand and promoting investment and consumption, the investment and consumer markets are accelerating. Many experts said that the supply-side structural reform will continue to deepen in the second half of the year, relevant policies and measures will be accelerated, and the huge potential of the domestic demand market will continue to be released, which will further highlight its supporting role for the economy.

　　A number of indicators are improving, releasing the signal of domestic demand recovery.

　　In June, the manufacturing PMI was 50.9%, rising from the previous month and standing in threshold for four consecutive months. The leading indicators released positive signals. Haitong Securities analysts Chen Xing and Ying Jiaxian pointed out in the analysis report that the new order index rose from 50.9% in May to 51.4% in June, rising for two consecutive months and hitting the second highest point in the year, exceeding the level of the same period last year, and the import index also rose from 45.3% in May to 47%, indicating that domestic demand continued to pick up.

　　Investment demand is also picking up. The latest investment data shows that the growth rate of investment in high-tech industries and social fields has turned from negative to positive.

　　Ding Yong, chief statistician of the Investment Department of the National Bureau of Statistics, said that with the steady investment policy taking effect, the investment in new projects continued to show a good trend. The planned total investment of new projects increased by 7.9% from January to May, which was 6.8 percentage points faster than that from January to April.

The sales volume of both types of vehicles reached a new high in the same period. According to industry insiders, like construction machinery products, the sharp jump in sales of commercial vehicles such as trucks is a strong proof that investment is picking up rapidly.

　　Behind a series of good data, structural reforms on the supply side are deepening and a series of policies are gradually becoming effective. The reporter of the Economic Information Daily learned that in the next step, China will issue opinions to support the steady growth, transformation and upgrading of private manufacturing enterprises, study and issue guiding opinions to promote the intelligent transformation of manufacturing industries, carry out pilot demonstrations on the cultivation of advanced manufacturing clusters, and formulate national hydrogen energy industry development strategic plans.

　　In addition, a number of heavy policy arrangements will be implemented, including the addition of two "1 trillion yuan" by the central government, the implementation of larger-scale tax reduction and fee reduction, efforts to stabilize and expand employment by all means, and greater macro-policy efforts to hedge the impact of the epidemic.

　　Promote consumption benefit to show the market and accelerate the replenishment

　　At present, the consumer market shows a trend of accelerating compensation. From the national situation, from January to May, the total retail sales of social consumer goods nationwide reached 13.87 trillion yuan, down 13.5% year-on-year, and the decline rate was 5.5 percentage points narrower than that in the first quarter. It decreased by 2.8% in May, and the cumulative decline for three consecutive months narrowed by 17.7 percentage points. At the local level, Zhejiang, Fujian, Hainan, Henan, Shanghai and other places have achieved a decline in consumption growth.

　　Li Danghui, deputy director of the Consumption Promotion Department of the Ministry of Commerce, pointed out that China’s consumer market has overcome the impact of the epidemic and achieved a monthly recovery. The consumption of basic living goods has continued to grow, upgraded goods are more active, and the retail sales of housing and transportation goods have improved. "This shows that under the normalization of epidemic prevention and control, the people’s demand and pursuit for a better life are still growing, reflecting the great development potential and strong resilience of China’s consumer market."

　　It is worth noting that many departments are still intensively introducing multiple consumption promotion policies to accelerate the release of domestic demand market potential. The reporter learned that in the field of commodity consumption, relevant departments are promoting the construction of new infrastructure and supporting green and intelligent consumption, among which the replacement and recycling of household appliances, automobiles and other bulk commodities will become the focus. In addition, the comprehensive promotion of foreign trade products to domestic sales has also injected new kinetic energy into the consumer market. On June 22nd, the General Office of the State Council issued the "Implementation Opinions on Supporting Export Products to Domestic Sales" to encourage foreign trade enterprises to expand sales channels and promote domestic consumption upgrading.

　　In the field of service consumption, the Ministry of Commerce, the National Development and Reform Commission, the Ministry of Culture and Tourism and other departments will continue to promote the orderly resumption of production in catering, shopping malls, culture, tourism, housekeeping and other industries, and adapt to new demands and trends, promote innovation in supply methods, develop new formats and new models, and stimulate market vitality with supply-side reform.

　　Guan Lixin, deputy director of the Institute of Circulation and Consumption of the Ministry of Commerce, said in an interview with the Economic Information Daily that despite the impact of the epidemic, the fundamentals of China’s long-term economic improvement have not changed, and the expectations of residents for a better life have not changed. From the central government to the local government, from the government to enterprises, a series of policies and measures to support commercial enterprises to resume production and promote residents’ consumption have been introduced one after another, which have boosted consumer confidence, enlivened the consumer market, enriched consumer supply and effectively promoted the accelerated release of China’s huge domestic demand market potential.

　　Sustained release of domestic demand potential and prominent economic resilience

　　Looking forward to the second half of the year, the huge potential of the domestic demand market will continue to be released, and its supporting role for the economy will be further highlighted.

　　Taking the export-to-domestic market as an example, Yang Guoliang, deputy director of the Foreign Trade Department of the Ministry of Commerce, pointed out that the accelerated release of domestic market demand has provided a domestic market for export industries such as electronic appliances, light industry, textiles and clothing, and agricultural products. From the perspective of investment, the promotion of new infrastructure, new urbanization and major projects in various places has brought new opportunities to export industries such as machinery and equipment, electrical and mechanical equipment and precision instruments. From the perspective of consumption upgrading, some foreign trade enterprises are shifting from traditional mass production to personalized customization, which can better meet the needs of domestic consumption upgrading. The rapid development of new consumption modes such as online sales and live broadcast with goods has also opened up sales channels for foreign trade enterprises directly facing consumer groups.

　　The analysis points out that the pulling effect of domestic demand market on foreign trade is only a microcosm of China’s economic resilience, and in other fields, this virtuous circle of economic development is also being opened. In Guan Lixin’s view, China is taking meeting domestic demand as the starting point and the end result of development, and making efforts to open up all links of production, distribution, circulation and consumption.

　　Guan Lixin pointed out that it is necessary to start with expanding the scale of consumption and promoting the upgrading of consumption physique, constantly create an effective supply that meets the new demand, introduce more goods and services that meet the needs of domestic consumers, increase investment around the supply-side structural reform, and strengthen the construction of infrastructure such as education, medical care and community services, give full play to the basic role of consumption and the key role of investment, consolidate the foundation of domestic large-scale circulation based on serving people’s livelihood, and form a domestic and international double-cycle pattern led by domestic consumption.

　　Meng Wei, spokesperson of the National Development and Reform Commission, said that in the future, we will vigorously tap the potential of releasing domestic demand, and the next step will focus on adapting, leading and creating new demand with high-quality supply, actively promoting the replacement and recycling of household appliances and automobiles, and accelerating the development and improvement of new consumption formats to take advantage of the trend, giving full play to the role of investment in the central budget, special bonds of local governments and special anti-epidemic bonds, and accelerating the construction of short-board areas.
