Home is a harbor that carries people’s dreams and happiness. No matter how technology develops, in the final analysis, she should be a better and more quality synonym for the appearance of home.

With the main consumers in the market changing from the post-80s to the more personalized post-90s and post-00s,Household productsField,consuming behaviorWith the change, the consumer groups are also accelerating the refinement, from once focusing on the use of men, women, children, adults, etc., to today’s maternal and child series, secondary series and many other sub-fields, especially the high-intensity life pressure brought by the acceleration of the industry, users are paying more attention to whether products and services can be improved.quality of life. In other words, people pay more attention to the value thinking of internal needs. And this kind ofMarket consumption patternThe change also determines that enterprises can only adapt to the changes in consumer behavior if they seek innovation and change.

In fact, people’s requirements for household appliances, including washing machines and refrigerators, have changed from meeting basic needs in the past to improving the quality of life today, including the comprehensive upgrade of basic performance, aesthetic pleasure, convenient use, healthy life and happiness index, which makes people’s homes more fashionable and warm.

Let the service have more digital application of "temperature"

In the era of digital and intelligent popularization, people basically spend more than half of their time dealing with digitalization every day, which makes life more convenient and faster and becomes an indispensable existence. For example, after the digitalization of home appliances, users can perceive the real effect of the whole scene in advance, and then buy when they feel satisfied after the experience, and enterprises can also accurately understand the preferences of users, so as to better link the needs of sellers and buyers.

Undoubtedly, digitalization can make life more warm. In the era of users’ home, enterprises need consumer consumption, so they must cater to the market, carry out digital transformation, and seek innovation and change. Haier Zhijia has grasped the bull’s nose of digital development many years ago and implemented a comprehensive digital transformation.

It is the central logic of Haier Zhijia’s digital transformation to improve users’ ideal experience. As Xu Meng, vice president of Haier Zhijia and general manager of China District, said, within Haier Zhijia, a chain group organization was built around users, and at the same time, with the support of business model, the reform of the whole system was realized, that is to say, the whole link of users was opened, and the whole process links such as contact, interaction, transaction, delivery and word-of-mouth were made visible on the platform. Of course, after the digital transformation of Haier Zhijia, it has well met the real-time needs of users, made Haier’s service more temperature, and won competitiveness for its own development.

On the road of digital transformation, Haier Zhijia focuses on efficiency first. Through the four digital reconstructions of objectives, organizations, mechanisms and processes, the whole process of all employees focuses on the transformation from "enterprise digitalization" to "digital enterprise". For example, in terms of business, they upgrade their business model from offline to online mainly through digitalization of six platforms: customers, users, products, services, marketing and logistics, which improves the user experience and repurchase rate.

Of course, in addition to the digital upgrade at the front-end client, Haier Zhijia mainly puts the supply chain, logistics, production and materials on one platform to quickly respond to market demand. At present, all nodes have improved their efficiency through the digital lean manufacturing platform, and the accuracy of time series planning has increased to 85%, the hourly output has increased by 9.3% year-on-year, and the logistics loading efficiency of order delivery has increased by 30%. At the same time, all designers and R&D personnel understand the needs of users, the market’s views on current products and future trends on the platform, and then develop a new SKU (inventory unit) which is more accurate and efficient.

It can be seen that, driven by the changes of the times and the transformation of consumption, the systematic logic of Haier Zhijia’s entire commercial circulation forces the enterprise’s business model to make subversive changes for users, from the previous business logic of ToB to all ecological and cooperative partners and channel providers to build a complete link of ideal whole-process experience around the needs of users. Haier Zhijia has accelerated into the user era.

Let a home realize a "differentiated" new experience around users.

For the home furnishing industry, how to seek change and innovation? In fact, the focus still needs to fall on the core factor of "users", so that users can feel the warmth of home and have a new sense of experience.

Nowadays, users have become the market leader, but there is a phenomenon: users don’t know exactly what they want or need, and many of their needs, such as the additional functions of household appliances in addition to their own basic functions, are actually created by the market.

From this point of view, the iterative upgrade of products should be ahead of consumers. That is to say, in the process of product research and development, enterprises need to pay more attention to the improvement of quality of life brought by products, rather than low-end products, under the premise of combining national policies and matching corresponding resources, and finally create differentiated products that users are willing to pay for. These products must be able to bring users life feelings and enjoyment that they did not have in the past.

For example, Haier Zhijia will show a casarte flat-embedded refrigerator on AWE this year, which can be beautifully embedded in the cupboard, beautiful and atmospheric, and also effectively saves the kitchen space. It really realizes the integration of home appliances and home improvement through the front of home appliances, which realizes the experience and feeling that the refrigerator did not bring in the past.

On the other hand, the consumer groups have become more personalized after 90 s and 00 s, and they have changed from the differences in the use of people who once paid attention to it to many sub-sectors such as maternal and child series and secondary series today, so the market needs to be re-laid.

For example, Haier Zhijia’s three-level brand strategy of "high-end brand, scene brand and ecological brand" has opened up a new track from products, scenes to ecology. It can be said that the strategic landing of Haier Zhijia’s third-class brand conforms to the trend of contemporary users’ consumption concept of "thousands of people". Xu Meng said that by arranging the brand matrix of super-high-end Fisher & Paykel, high-end casarte, Volkswagen Haier and Young leader, we can find suitable product solutions for different groups, better meet the consumption behavior of different groups and better adapt to the current consumption stratification.

After meeting the needs of different users, Haier Zhijia also has a deep insight into the new consumption concept of the Z generation youth in the family field. Compared with the former consumption concept of "I will buy whatever the enterprise produces", contemporary young people pay more attention to the phenomenon of solutions and lifestyles. It is often difficult to make their consumption land only by using products. At the same time, their consumption concept is just one stop at a time, and time is more important than money. Therefore, through the landing of the smart home scene brand, Haier Zhijia provides a new life with higher quality, convenience and wisdom, which is no longer a commodity, but a solution covering home improvement, home, home appliances and home life.

In addition to satisfying users and reassuring them, the distance between enterprises and users is also an important success or failure point in today’s market. However, Haier Zhijia has changed people looking for goods in the past into people looking for goods today. For example, offline casarte is entering the shopping mall in an all-round way, and it is not a traditional household appliance, but a scene experience of a high-end lifestyle jointly built with the ecological side, and such a "differentiated" smart life experience is constantly entering the families of millions of users.

When night falls, the lights are dim, and the sleep mode of smart home is quietly started. Curtains are automatically closed, the ambient temperature is automatically adjusted, the mattress senses the body posture, and the height and hardness of the pillow are automatically adjusted, so that the human body can get ideal comfort and support. The speaker on the bedside table will play soft music, which will make people fall asleep gradually. When the human body enters deep sleep, it automatically adjusts the volume to keep a quiet sleeping environment … This has been the daily life of Haier Zhijia users.

The effective implementation of Haier Zhijia’s "three-level brand strategy" has met the practical needs of users’ consumption behavior changes to a certain extent, which is a gospel for users. From this aspect, Haier Zhijia has always been guided by the needs of users, that is, "user-centered" strategic layout, promoting enterprise reform and improving the quality of users’ consumption every time.

Today, people’s home life is moving towards wisdom; What will it be like tomorrow? Perhaps, as Xu Meng said, it is to provide users with clothing, food, shelter, entertainment and smart life scenes, and feel the happiness of thousands of people!

In the era of smart life, how can innovative technology empower space? How can user needs be realized? How does the smart lifestyle continue to evolve? Haier Zhijia follows the needs of users with innovation, accurately grasps the industry trend and has insight into the next decade. At 18: 30 on April 27th, Haier Zhijia once again joined hands with AWE to start a smart life and look to the future-Haier Zhijia X36 "See 2033" joint theme live broadcast, inviting thousands of users to enter Haier Smart Life Experience Field together, so stay tuned!

Consumer price index (Consumer price index (CPI) is a relative number that measures the price level of consumer goods and services over time, and reflects the changing trend and degree of the price level of goods and services purchased by residents. Its annual change rate is usually used to reflect the degree of inflation or austerity; CPI and its sub-indices are also important reference for calculating the real value of GDP, assets, liabilities, consumption and income.

　

The compilation method of CPI is to select representative specifications from many measurement objects, collect their price data, calculate the average price and individual price index of these representative specifications, then calculate the basic classification price index by geometric average, and then calculate the small, medium and large price indexes step by step by weighted average method until the total price index. According to the interpretation of CPI indicators by the National Bureau of Statistics, the calculation process is as follows:

　

First of all, the National Bureau of Statistics and local statistical departments determine the classification for calculation.CPI’s goods and services and survey outlets. According to the sampling survey data of household consumption expenditure of urban and rural residents in China, the National Bureau of Statistics uniformly determines the categories of goods and services, including: food, tobacco and alcohol, clothing, housing, daily necessities and services, transportation and communication, education, culture and entertainment, medical care, and other supplies and services, which basically cover all consumption contents of urban and rural residents. About 500 cities and counties were selected nationwide, and there were 63,000 survey outlets to determine the collection price, including grocery stores, department stores, supermarkets, convenience stores, professional markets, specialty stores, shopping centers, farmers’ markets and service consumption units.

　

Second, according toIn the way of "fixed person, fixed point and fixed time", the statistical department sends investigators to the survey outlets to collect prices on the spot. At present, there are about 4,000 price investigators in 500 cities and counties in 31 provinces (autonomous regions and municipalities). The frequency of price collection varies from commodity to commodity. For the food in CPI, such as grain, pork, beef, mutton and vegetables, which are closely related to residents’ lives and have relatively frequent price changes, the price is investigated once every five days; For most industrial products such as clothing, shoes and hats, durable consumer goods, transportation and communication tools, the price is investigated 2-3 times a month; For water, electricity and other government pricing projects, the prices are investigated and verified once a month.

　

Finally, according to the original price data after the audit, calculate a single commodity or service item andPrice indices of 268 basic categories. Then calculate the category price index and CPI according to the corresponding weights of each category.

　

our countryThe weight in CPI is mainly determined according to the detailed proportion of consumption expenditure of various commodities and services of urban and rural households in China. CPI summary calculation method adopts chain pull formula to compile month-on-month ratio, month-on-month ratio and fixed base price index.

　

CPI is equal to 100, indicating that the comprehensive price has not changed during the reporting period compared with the base period; The consumer price index is greater than 100, which means that the comprehensive price rises in the reporting period compared with the base period. The higher the price index, the more the price rises. The consumer price index is less than 100, which shows that the comprehensive price in the reporting period is lower than that in the base period.

　　CCTV News:Recently, the National Development and Reform Commission, the Ministry of Civil Affairs, the Ministry of Veterans Affairs, and the China Disabled Persons’ Federation jointly issued the Implementation Plan for the Bottom Line Project of Social Service Facilities during the Tenth Five-Year Plan period. The "Implementation Plan" proposes that by 2025, with the joint efforts of relevant central departments and governments at all levels, the conditions of social welfare, retired military personnel and disabled service facilities will be further improved, the professional, standardized and intelligent level of management services will be continuously improved, the staffing will be further strengthened, and the reform of institutional mechanisms such as funeral and special care services for retired military personnel will take new steps.

　　The "Implementation Plan" clarifies that during the "14th Five-Year Plan" period, the investment in the central budget will focus on supporting three types of projects, among which there are service facilities for veterans, mainly including martyrs memorial facilities, military cemeteries, glorious homes, etc., and support each province to build at least one regional special care hospital serving the whole province. Compared with the "Thirteenth Five-Year Plan" period, martyrs memorial facilities and military cemeteries have added new support content for investment in the central budget.

According to the "Beijing Release" WeChat WeChat official account news, the Beijing Center for Disease Control and Prevention issued a health reminder:Covid-19 can effectively prevent Covid-19 infection through close contact and respiratory droplets transmission. Personal protection such as wearing a mask, washing hands frequently, regular ventilation and keeping a safe social distance can effectively prevent infection. In order to better protect the health of themselves and their families, please ask the general public and friends to participate in, understand, support and cooperate with various epidemic prevention and control measures, earnestly fulfill their personal epidemic prevention responsibilities, scientifically prevent epidemics, and be the first responsible person for their own health.

One is to wear a mask. Wear masks in indoor and outdoor crowded places, when taking elevators or public transport; When fever, dry cough, fatigue, sore throat and other symptoms appear, it is recommended to wear a medical surgical mask or above when seeking medical treatment in the hospital; Masks should be replaced in time, and the cumulative wearing time of each mask should not exceed 8 hours.

The second is to wash your hands frequently. When going out and returning home, caring for the elderly, children and patients, touching the mouth, eyes, nose, coughing or sneezing, cleaning up garbage, touching public facilities such as express delivery, elevator buttons, door handles, etc., you should wash your hands or disinfect your hands in time.

The third is constant ventilation. Open the window for ventilation at proper time, 2 ~ 3 times a day for 20 ~ 30 minutes each time; When there are many people at home, patients or visitors, it is recommended to open the window for ventilation; When there are isolated people at home, the room where they are located should close the door and open the window separately for ventilation.

The fourth is to gather less. Try not to go to crowded places with poor air circulation, stay away from people with fever or cough symptoms, reduce gathering activities and maintain a safe social distance.

The fifth is to maintain environmental sanitation. Daily household cleaning is the main task, and preventive disinfection is carried out when necessary; Kitchen utensils, countertops, tableware, etc. should be cleaned and disinfected in time; Regularly clean and disinfect the sanitary ware and floor in the toilet. When the surface is dirty or moldy, it should be cleaned and disinfected in time; Cover the toilet before flushing and keep the trap water sealed.

Sixth, actively vaccinate COVID-19 vaccine. The whole population in Covid-19 is susceptible, and the elderly are the most vulnerable group, with a high proportion of basic diseases. They are the high-risk group that will cause severe illness after being infected with Covid-19. Vaccination with COVID-19 vaccine is always one of the most effective preventive measures. It is suggested that the elderly who meet the vaccination conditions should be vaccinated as soon as possible, and the booster immunization should be completed as soon as possible after three months of complete vaccination.

Seventh, develop a healthy lifestyle. Strengthen physical exercise, adhere to the law of work and rest, ensure adequate sleep, maintain a healthy mentality, eat healthily, quit smoking and limit alcohol, maintain a healthy mentality, and do not believe in rumors or spread rumors.

Eighth, do a good job in health monitoring. Make good use of nucleic acid detection and antigen self-test. If you have symptoms such as fever and dry cough, don’t go to work or school with illness, don’t take part in social activities, don’t take public transportation, wear a mask, and go to the hospital fever clinic for investigation in time to reduce the risk of family transmission and cooperate with the implementation of various prevention and control measures.

　　[car home industry]　　In the movie "shaolin soccer", A Xing, omega supreme’s leg, played by Stephen Chow, looked up and muttered "I feel that they are all back" when he saw your other disciples find their state and kill the quartet. At the beginning of this month, when some car companies announced the sales volume in April first, the reaction of the outside world was the same as A Xing’s. They thought that all car companies had recovered their status and the China auto market had returned to that era full of growth.

　　However, contrary to expectations, the beauty of the past is only suitable for recollection, and it is difficult to find it back.

　　According to car home’s incomplete statistics, 24 car companies have released April sales data, of which 11 companies still cannot achieve positive sales growth year-on-year; From the perspective of cumulative sales in 2020, only one company, FAW Hongqi, can achieve positive year-on-year sales growth from January to April, and the cumulative sales of "head car companies" such as SAIC Volkswagen, SAIC GM and SAIC-GM-Wuling have dropped by as much as 50.4%, 47.7% and 46.7% respectively.

　　Next, let’s comment on the sales performance of car companies in April.

Joint venture car companies: What about good retaliatory consumption?

　　Looking at the sales performance of joint venture car companies in April, it is not difficult to find that the legendary "retaliatory consumption" has not arrived. Among the 11 joint venture car companies, only 5 can achieve positive growth in April. Unfortunately, SAIC Volkswagen and SAIC-GM, the former sales overlords, are not among them.

　　As a resident player of Top 3 in China passenger car market, SAIC-GM achieved 110,002 vehicles in April, down 12.4% year-on-year, and its sales volume was lower than that of SAIC-Volkswagen, SAIC-GM Wuling and Changan Automobile. Before FAW-Volkswagen announced its sales volume, SAIC-GM had already lost the top three.

"Pioneer"

　　According to Shi Hong, deputy general manager of SAIC-GM and general manager of SAIC-GM Sales Company, from February to March in 2020, SAIC-GM devoted all its energy to supporting dealers, and began to officially rush sales in April. Like other car companies, SAIC-GM also regards product offensive as the biggest magic weapon to rush sales. According to statistics, in April alone, the company launched seven new cars through "cloud listing", including many heavy models such as Pioneer and Cadillac CT4.

　　In fact, for SAIC-GM, the biggest change in 2020 is not the product offensive or the organizational structure, but that this enterprise has finally abandoned the radical "all-in-one three-cylinder strategy". In April, the new Yinglang, the new Ke Lu Ze and other previous "all-in-one three-cylinder" models all launched four-cylinder engine versions. Giving up "persuasion" and catering to China consumers is the hope of SAIC-GM in 2020.

　　For Changan Ford, which has been trying to revive, it is not easy to sell 20,465 new cars in April and achieve a positive growth of 38.3% year-on-year. We should know that according to the statistical caliber of Changan Automobile, Changan Ford achieved positive sales growth in only one month (December) in 2019, but after entering 2020, the company has achieved positive growth twice in January and April, which has given Changan Ford a shot in the arm.

　　Since October 2018, in order to reverse the unfavorable situation in China, Ford Motor Co., Ltd. has not started to improve its position in the China market, and has listed the China market and the North American market as the company’s two core markets. Ford China directly reports to the global headquarters; Since then, Chen Anning, a veteran, has been appointed as Vice President of Ford Motor Company Group and President and CEO of Ford Motor Company China.

『(|)』

　　In September, 2019, Ford Motor Company set up a research institute for Changan Ford to enhance its R&D capability, accelerate product upgrading and intelligent manufacturing level, and launch a revival offensive with products that are more in line with China consumers’ aesthetic and usage preferences. In the "acceleration plan" announced at that time, Changan Ford will launch more than 18 new products in the middle of 2019 -2021, including 5 new energy vehicles.

　　From the perspective of sales in April 2020, Changan Ford’s self-help did work. Ruiji, which was just launched by this company at the end of 2019, surpassed Fox and Forex in April and became the "new thigh" of Changan Ford’s sales. The first model launched in the "acceleration plan" has achieved such results. After the sixth generation of explorers went on the market in June and the product offensive was officially rolled out, Changan Ford is very hopeful to turn around the crisis in 2020.

Mazda CX-30

　　Changan Mazda sold 11,761 vehicles in April, a year-on-year increase of 36.8%. Unlike Mazda’s overseas painting style of "not pushing a new car for two years", Changan Mazda’s heavy product Mazda CX-30 has now started pre-sale and will be listed on May 28th. For Changan Mazda, whose product line is relatively thin and new products are launched slowly, the sales performance of Mazda CX-30 will directly determine the future development pattern of this enterprise.

China car companies: the red flag won glory this time.

　　As of press time, a total of nine China auto companies announced their sales results in April, among which five companies’ sales increased year-on-year, and the overall situation was still optimistic.

　　In April, SAIC-GM-Wuling won the second place in China passenger car market, only selling 200 cars less than SAIC-Volkswagen. Strangely enough, while other companies were growing month-on-month, the sales volume of SAIC-GM-Wuling declined month-on-month. From this point of view, this company may have got rid of the impact of the epidemic.

　　Although the sales volume has achieved continuous positive year-on-year growth, SAIC-GM-Wuling has also made a lot of "blood" for this. It is reported that in order to stimulate automobile consumption, SAIC-GM-Wuling launched a total of 2 billion yuan in car purchase subsidies twice in February-April, covering all its models such as commercial vehicles, special vehicles, passenger cars and new energy vehicles; During the "May 1" period, this enterprise issued another 1.5 billion yuan travel coupons. When many enterprises reduced their costs by means of "salary reduction and layoffs", SAIC-GM-Wuling’s "retrograde" was full of enthusiasm.

　　In order to further increase sales, SAIC-GM-Wuling also planned a product offensive. It is understood that the company will launch 10 new cars in 2020, of which 6 are brand-new models and 4 are new models; Wuling brand will also launch a brand-new brand strategic plan during the year. Perhaps the end of 2020 is the most fair and objective time to evaluate the sales performance of SAIC-GM-Wuling.

　　BYD achieved sales of 31,809 vehicles in April, a year-on-year decrease of 15.9%; From January to April, the cumulative sales volume was 93,082 vehicles, a year-on-year decrease of 40.1%. Although the sales target for 2020 has not yet been announced, it is not easy for BYD to maintain the year-on-year sales even in terms of current sales results.

"Han"

　　In terms of sales structure, BYD sold 18,814 fuel vehicles in April, a year-on-year increase of 36%; 12,995 new energy vehicles were sold, down 45.9% compared with the same period last year. For BYD, the biggest attraction in 2020 is the upcoming listing in June, equipped with self-developed Ferrous lithium phosphate blade battery technology, BYD DiPilot intelligent driver assistance system and DiLink 3.0 intelligent network connection system.

　　For this car, BYD executives are very confident. Zhao Changjiang, general manager of BYD Auto Sales Co., Ltd. even publicly published on social media such remarks as "Tesla’s card is finished, it’s our turn to play" and "Han has surpassed Tesla in acceleration, battery life and charging speed, and in addition, the assisted driving is at the same level". However, under the introduction of the new subsidy policy and the price drop of Model 3, Han, who has not yet been listed, is indeed facing no small challenge. Whether this car can finally break through the interception of Model 3 and lead BYD to find its state remains to be tested by the market.

　　For an old brand with a new face, FAW Hongqi’s recent sales performance is excellent. In April, the company’s sales reached 14,500 vehicles, a year-on-year increase of 168%; From January to April, the cumulative sales volume exceeded 39,500 vehicles, and it was the only company (as of press time) that achieved positive growth in cumulative sales volume from January to April. In this regard, Hongqi did win glory for China brand.

Red Flag H9

　　However, it must be admitted that the reason why the cumulative sales volume increased year-on-year was also caused by the low sales base of FAW Hongqi. In addition, despite the rapid sales growth of this company, it has only completed one-fifth of its sales target of 200,000 vehicles so far, and 2020 is still full of pressure for FAW Hongqi.

　　In terms of products, the main action of FAW Hongqi in 2020 is to bring the medium and large-sized red flag H9 designed by former Rolls-Royce design director Giles Taylor and China designer Ding Yangfeng to the market, and release the pure electric SUV red flag E115. However, considering the positioning of these two products, their prices will certainly not be too close to the people, and it is not known how much they can contribute to Hongqi’s sales target.

Luxury brand: "overlord" translocation

　　Before 2019, Cadillac was the most detached existence among second-tier luxury brands, but when Lexus continued to heat up, Cadillac’s dominance of second-tier luxury brands was constantly threatened. After entering 2020, the competition in the second-tier luxury brand market suddenly escalated. Lexus officially defeated Cadillac with a total of 51,167 vehicles and became the new "overlord" in this field.

Cadillac CT4』

　　Since the second half of 2019, Cadillac began to switch between new and old products. The original sales models Cadillac ATS-L and Cadillac XTS were discontinued one after another. The brand once faced the dilemma of no car to sell. However, with the launch of Cadillac CT5 and Cadillac CT4, the company’s "3+3" product layout has been formed, officially bidding farewell to the most difficult period.

　　Compared with Cadillac, which is about to switch products, Lexus, which is currently on the "throne", is not easy. In terms of production capacity, Toyota has decided to cut the production capacity of Japanese factories by 50% in May and 40% in June. As a result, Lexus, which has not achieved domestic production, will encounter a bottleneck in production capacity supply, and this is also the best time for Cadillac to overtake.

"lexus es"

　　Although it is impossible to compete with Cadillac and Lexus for the time being, compared with itself, Volvo’s report card in April is quite excellent, with a sales volume of 14,698 vehicles and a year-on-year increase of 21%, setting a new record for the company’s sales in China in April. The monthly sales of its main model Volvo XC60 increased by 22% year-on-year, which also set the highest monthly sales record of Volvo Cars in China market.

　　Editor’s summary:More than half of the 24 car companies achieved positive sales growth in April. Although this report card is not bad, it obviously falls short of the expectation of "retaliatory consumption" from the outside world. Although compared with the first quarter, the sales performance of car companies rebounded significantly in April, it was still not enough to make up for the trauma caused by the previous decline in sales.

　　However, compared with before the epidemic, the "skills" of car companies are obviously richer. They have learned how to better market and sell cars online, and also learned how to achieve win-win results and mutual benefit with dealers. As long as the car companies can continue to carry forward these "skills", it is only a matter of time before they can find their normal state and achieve further sales growth.

Author: Shen Chunlei

Ten academic papers (9 SCI and 1 new journal with high starting point) were published in 4 years, including 6 first authors and 4 co-authors. The total impact factor of SCI papers was about 93.

Liu Ying, a Ph.D. student at University of Science and Technology Beijing, has recently attracted a lot of attention due to this brilliant academic achievement.

At present, Liu Ying is studying in the Italian Institute of Technology, following Professor Liberato Manna, a big bull in chemistry and deputy editor of the internationally renowned journal Nano Letter. Liberato was ranked 24th in the ranking list of the top 100 cited chemists in the world published by Thomson Reuters from 2000 to 2010.

In March this year, Liu Ying will return to China and take part in the defense of doctoral thesis. Now he has received an offer from a key university in central China to directly hire a researcher. It can be said that Liu Ying has been ahead of her peers in the starting link of scientific research, so how did she do it?

Liu Ying is in Europe (Norway)

I would rather reread than change my major.

In September 2012, Liu Ying became a freshman at University of Science and Technology Beijing, majoring in industrial design.

When she first entered school, Liu Ying’s major courses were sketching and color, but she found that she didn’t like drawing very much. So, she came up with the idea of changing her major and put it into practice. In the first half of the freshman year, Liu Ying submitted an application to the school to transfer to the major of materials science and engineering, and finally passed the interview.

In September 2013, Liu Ying became a freshman again, majoring in materials science and engineering. Because of the great difference between the two subjects, she can only accept the price of changing her major-demotion.

However, Liu Ying is satisfied with his new major. Later facts also proved that she did the right thing in this multiple-choice question. During the undergraduate course, Liu Ying achieved excellent results and won many honors such as "People’s Scholarship" and "Three Good Students". In 2017, she obtained the qualification of insurance research in our school.

After changing majors, Liu Ying’s study is like a duck to water. In the first year of master’s degree, she applied for the qualification of master’s degree and doctoral degree.

Formal scientific research work has just begun. Liu Ying studied under Xia Zhiguo, a professor from the Department of Materials Physics and Chemistry, University of Science and Technology Beijing, mainly engaged in the synthesis and luminescent properties of inorganic perovskite nanocrystals.

She was shocked when she first saw with the naked eye that the synthesized nanocrystals showed bright green light. "The luminous efficiency of general materials is not so high."

Later, as the research on perovskite continued to heat up, Liu Ying began to carry out research on related luminescence fields around perovskite materials. In 2018, as co-first author, Liu Ying published an article entitled "Synergistic Preparation of High Stability/High Efficiency Perovskite Nanocrystals by Water Post-treatment Strategy" in Chemistry of Materials.

This is the first research paper related to perovskite published by Liu Ying. In 2018, Liu Ying published two papers as the first author and one as a co-author.

Two articles a year, writing quickly and correcting slowly is the trick.

From 2019 to 2021, Liu Ying published two papers every year.

Among them, Liu Ying’s most satisfactory paper was published in Angewante Chemie International Edition in 2020, which proposed a design idea of rare earth-doped lead-free perovskite nanocrystals, expanding its luminescent application.

Write quickly and change slowly, which is the paper writing skill summarized by Liu Ying. This article took about two weeks from the beginning of writing to the completion of the first draft, and it took about three to four weeks for the tutor to guide the revision of the paper. From the preliminary preparation to the final publication, it took about a year.

Liu Ying is very grateful to his tutor Xia Zhiguo and his research group. The tutor is very strict about the progress of scientific research, and the members of the research group need to submit weekly reports to the tutor to report their own experiments and work progress. The tutor asked the students to be good at finding and summarizing problems while ensuring the experimental time.

"A large number of experiments have accumulated to build a reasonable scientific framework for the paper, and then select appropriate journals to contribute according to the research field." In Liu Ying’s eyes, it is not difficult to send papers. Her tutor has always stressed that don’t send papers for the sake of sending papers, do more experiments, think and summarize more. In such an atmosphere, the quality and quantity of papers will not be bad.

"We are studying luminescent materials, and there are many scientific problems to be further discussed." Xia Zhiguo believes that publishing a paper is like selling your own research results, and only good results can get big sales.

He also asked students to go out more, participate in academic exchanges and integrate into the academic community as soon as possible. For example, Liu Ying’s article "Preparation of Perovskite Nanocrystals with High Stability/High Efficiency by Water Post-treatment Strategy" mentioned above was presented as an excellent poster paper at the Seventh National Academic Conference on Luminescence Properties of Doped Nanomaterials.

So, why did Liu Ying choose to study in Italy? It turns out that Liu Ying had previously cooperated with Liberato, and the research of Liberato’s research group is in line with her research on lead-free perovskite nanocrystals in China. So, she contacted Liberato, received an invitation letter, and later applied for a scholarship from the China government.

In February, 2021, Liu Ying officially went to Italy and began his one-year study and life.

I won’t stay in Beijing after graduation, but I will continue to do scientific research.

In China, Liu Ying will arrive at the laboratory before 8 am on weekdays, start work and leave the laboratory at 22 pm; In Italy, according to the working schedule of the research group, Liu Ying’s daily working hours were shortened by four hours. In her words, "When in Rome, do as the Romans do. If it is too early or too late, there will be no bus."

Compared with the pace of work and life in China, Liu Ying obviously felt much slower in this year. In a strange country and a brand-new environment, there will be some problems and many maladjustments. In the experiment, from synthesis to testing and calculation, the progress of each stage is very slow. What Liu Ying can do is to learn how to make rational use of time and plan his study life while slowly adapting.

Liu Ying is doing experiments in an Italian laboratory.

Talking about work and experiments, Liu Ying can always explain; When it comes to achievements and life, Liu Ying is a little shy.

Although Liu Ying rushed very hard in the initial stage of scientific research, she ran on the next way, hoping to advance at a constant speed. "I shouldn’t stay in Beijing after graduation. The work and life here are a little stressful for me." Liu Ying, who is about to return to China, is ready for her graduation. "I will settle in a second-tier city and continue my research in colleges and universities."

"I respect and firmly believe that my students’ choices are correct." As the tutor Xia Zhiguo said, "I hope students can continue to do scientific research and do what they like."

The 12-inch MacBook was an unexpected surprise at Apple’s spring conference. Many people are already eager to move, and they can’t wait to get rid of the MacBook Air at hand. Let’s first follow the foreign media to see how the new 12-inch MacBook performs.

The overall body of the 12-inch MacBook still adopts the classic wedge design on the Air, but the transition of the body is smoother. The thickest part is 13.1 mm and the weight is only 920 grams. From the data alone, it is difficult for us to intuitively feel how thin this product will be. The Verge reporter said after getting started that the 12-inch MacBook is much thinner than you think, and after the screen is turned on, the overall body will feel lighter.

In order to match the size of the whole machine, Apple redesigned the motherboard. The onboard memory jumped from 8GB, and the hard disk space was 256GB and 512GB. The workmanship of the whole machine is apple’s consistent standard, with a solid body and a solid feel.

However, there are two obvious changes in appearance besides thinness. One is that the Apple logo on the top of the fuselage is no longer the previous hollow light-transmitting design, but adopts a design similar to that on the iPhone and iPad. The second is that the 12-inch MacBook uses the same three colors as the iPhone, namely silver, gold and deep gray.

The redesigned keyboard adopts butterfly structure, the area of key cap is increased, the key spacing is shortened, but the key stroke is also shorter:

When typing on this keyboard, you will wonder if you are really typing. The overall input experience is similar to typing on a touch screen.

However, ArsTechnica’s evaluation of the keyboard is more conservative, thinking that as a writer who often deals with the keyboard, he has a strong subjective judgment on the keyboard. However, from the design point of view, the keyboard of the 12-inch MacBook seems to have a certain gap with the previous Mac products, but it does not rule out that after several days of use, the newly designed keyboard may change many people’s preconceived judgments.

For Apple’s newly designed Force Touch function, ArsTechnica said after getting started:

After pressing the touchpad, the built-in pressure feedback device will give a slight vibration. At the same time, the strength and sensitivity of feedback can be set in the system. This makes it very close to the traditional touch pad, and the only difference is that Force Touch can simulate the touch of pressing at any position on the touch pad.

In addition to the 3.5mm headphone jack on the right side of the fuselage, the USB-C interface on the left side has almost become the only outlet for data transmission inside and outside the 12-inch MacBook, which supports HDMI, VGA and Mini DisplayPort video output, and even shoulders the power supply for the notebook itself.

Paranoia, like Apple, will be so radical to adopt a single interface design. As mentioned in the previous 12-inch MacBook review article, such an advanced design requires a keen sense of smell and sufficient courage for new technologies, which is also in line with Apple’s consistent style. Previously, it was the first in the industry to abandon floppy drives, optical drives and mechanical hard disks.

Considering the need of fuselage expansion, Apple officially provided a multi-purpose adapter with a price of $79, which supports HDMI, standard USB and USB-C, and USB-C connects standard USB wires. What is certain is that in the future, Apple or third-party peripheral manufacturers will provide more types of patch cords.

Core M processors have appeared in many PC products. The 12-inch MacBook is also equipped with a 14nm Broadwell architecture Core M processor, which has two models, namely 1.1GHz (2.4GHz Turbo) Core M-5Y31 and 1.2GHz (2.9GHz Turbo) Core M-5Y71. According to ArsTechnica’s calculation, the performance of Core M is equivalent to that of Core i5 and i7 installed on MacBook Air in 2012. The biggest advantage of Core M lies in its excellent power control, with the highest power consumption of only 5W.

The 12-inch MacBook is equipped with a display screen with a resolution of 2304×1440, which is about 226ppi. Many people may have concerns about Core M driving such a high-resolution screen. ArsTechnica gives a comparison:

The GPU driving the first generation of 13-inch Retina MacBook Pro is the HD 4000 built in Ivy Bridge, while the HD 5300 graphics card is used on the 12-inch MacBook. It is not a problem to drive the screen with 2304×1440 resolution with its performance. There was no delay in the on-site demo, and the system animation effect of OS X was also very smooth.

Engadget also talked about the possible performance problems of the 12-inch MacBook when he started this new product, and thought that there were many good choices for Windows products at similar price points, such as the latest Dell XPS 13. The starting price of the 12-inch MacBook is 9288 RMB. Apple China official website has not given a clear delivery time yet, and the global delivery time is April 10th.

The comedy sci-fi movie Crazy Alien, directed by Ning Hao and starring super comedies Cass Bo Huang and Shen Teng, was officially released today. As the third part of the "Crazy Series" directed by Ning Hao, the film tells a cosmic absurd comedy story that happened in China. Shen Teng, Bo Huang, is pleasantly surprised, playing wits with the alien "Chica" skillfully, and the "grassroots counterattack" between the mysterious alien visitors and the ordinary people is expected. After the preview of the film was released, many netizens said, "I actually missed this immortal combination before", "Bo Huang and Shen Tengguang stood there and I wanted to laugh" and "I can’t see this lineup in the Spring Festival Evening now, but Bo Huang and Shen Teng must see it". Today, the film will return to the big screen to meet the audience, and an absurd and crazy journey of joy is about to appear. Let’s taste this "cosmic" hilarious story again and laugh together!

Bo Huang and Shen Teng join hands with aliens to go on a crazy trip. The "Circus" style poster is mysterious and eye-catching

The film surprises a poster released today, which depicts the crazy life of Bo Huang Shen Teng in a lively and grotesque circus style. Three striking colors, red, yellow and blue, are selected to collide in the color matching of the poster, which highlights the joyful and interesting overall style of the film. However, the two protagonists, Bo Huang and Shen Teng, sit side by side with scars on their faces and bandages on their heads. The seemingly stable mental state hides the "cry" that is about to break out, and the striking words on the poster are "2024 is tired, destroy it!" Echoing each other, we can’t help wondering what kind of crazy journey this pair of he is my brother has gone through. In addition, an alien’s hand is stretched out in the upper left corner of the poster, and the index finger seems to want to touch something, which seems to imply that the experiences of the two protagonists are related to the control of aliens. Many details revealed in the cheerful and contrasting poster attract the audience to go into the cinema to find out.

The film, starring Bo Huang and Shen Teng, can be called the "ceiling" of the "cosmic" comedy Cass. The "chemical reaction" produced by the combination of he is my brother played by the two people in the film makes netizens sigh that "I want to laugh when I stand there". In addition, the film also has a group of comedy comedians to join in the surprise, and Xú Zhēng specially starred in the foreign object "Chica" in the film; The appearance of Yu Hewei, Lei Jiayin and other national familiar actors makes people shine at the moment. The film was released in the Spring Festival in 2019, and became the mainland box office champion of comedy movies in 2019 with a box office of 2.213 billion. With the approach of 2025, the re-release of the film brings a happy atmosphere of "celebrating the New Year in advance" to the audience. After the release of the movie’s release, the audience sighed on social platforms, such as "I am looking forward to the release, and I feel that I will celebrate the New Year ahead of schedule when I see Bo Huang Shen Teng", "I missed the previous release, so I must make up this movie ticket this time" and "I want to brush it again", hoping to enter the theater again to witness the surprise combination of the two comedy masters. "Cosmic-level" super-card companies gathered together to stage a "Cosmic-level" joke suitable for decompression at the end of the year and open a comedy feast suitable for the whole family to watch movies!

Local elements and sci-fi themes surprise and collide, and the mental state is leading, making a year-end declaration for the current audience.

2024 is a special year. Looking back at the end of the year, it seems that history has come back once again. Many netizens exclaimed on social platforms that "I think it’s terrible, I seem to have traveled back to 2019" and "all this is too similar to 2019". The various details in the film are in one-to-one correspondence with the current reality. Shen Teng’s classic line "Destroy, Hurry, Tired" has once become a "high-frequency vocabulary" in recent years, and many viewers lamented that "the mental state of this film is really advanced, directly five years ahead of me" and "the original real prophet has already appeared". The film was released again at the end of 2024, and the advanced mental state of Bo Huang and Shen Teng, the two brothers, was also in line with the life creed that young people dare to say and go crazy, and became the "strongest excuse" for the declaration of contemporary young people at the end of the year.

As the third work of "Crazy Series" directed by Ning Hao, the film tells a hilarious sci-fi story with China local temperament. Geng Hao (Bo Huang) and Dafei (Shen Teng), brothers of "Niu Ma", who are struggling for their lives, accidentally meet Chica, a higher creature in the Milky Way, and encounter a series of incredible "mysterious forces", and stage a ridiculous journey. Geng Hao, played by Bo Huang, lives hard and insists on inheriting the intangible monkey drama, but it is despised. Dafei, played by Shen Teng, dreams of making a fortune, but has repeatedly fallen into the investment trap. The film also incorporates many traditional folk elements in China: intangible monkey drama, Chinese medicine massage, traditional opera, etc., which makes people feel strong Chinese local characteristics. Through the comedy expression of grounding gas, the film starts from the life of the little characters and blends into the unique Chinese fireworks. Under the surprise collision between the local and sci-fi, I hope to bring the audience a new experience of watching sci-fi movies.

The film Crazy Alien is directed by Ning Hao, starring Bo Huang and Shen Teng, and produced by Huanxi Media Group Co., Ltd., Bad Monkey Film and Beijing Light Film Co., Ltd. The film was released today, and an absurd and crazy hilarious journey was staged. Meet the audience and bid farewell to this year happily!

　　At 18: 00 on March 16, the Central Meteorological Observatory continued to issue blue rainstorm warning and strong convection warning, and issued blue blizzard warning, prompting the affected areas to continue to pay attention to early warning information, prevent disasters that may be caused by local heavy rainfall and strong convection, and do a good job of prevention.

　　The blue rainstorm warning shows that it is expected that there will be heavy rain in southern Henan, central and eastern Hubei, most of Anhui, most of Jiangsu, northwestern Zhejiang, northern and central Shanghai, northwestern Jiangxi, northern and southern Hunan, northeastern Yunnan and other places from 20: 00 on March 16th to 20: 00 on March 17th. Among them, there will be heavy rain in parts of southeastern Henan, central and southern Anhui and central and southern Jiangsu, and there will be heavy rain in southern Anhui (100-120 mm).

　　National forecast map of heavy rainfall area

　　Micro-science of meteorological disaster prevention

　　The blue warning of strong convection shows that from 20: 00 on March 16 to 20: 00 on March 17, there will be 8-10 thunderstorms or hail weather in parts of central and southern Anhui, central Jiangsu, eastern and southern Hubei, central and northern Hunan, northwestern Jiangxi, southern Sichuan, central and southern Guizhou, eastern Yunnan and northeastern Guangxi. There will be short-term heavy rainfall in parts of southern Henan, central and southern Anhui, central and southern Jiangsu, northern and eastern Hubei, Hunan, Jiangxi, western Zhejiang, western and northern Fujian, southeastern Sichuan Basin, southeastern and central Guizhou, northeastern Yunnan and northeastern Guangxi, with an hourly rainfall of 20-50 mm and a local area of more than 60 mm. It is estimated that the main impact period of strong convection is the night of 16th.

　　National forecast map of thunderstorm, gale or hail falling area

　What should I do if a strong convection comes?

　　The blue warning of blizzard showed that there was heavy snow (10 ~ 18 mm) in parts of south-central Inner Mongolia, northwestern Shanxi, northwestern Hebei and mountainous areas in northwestern Beijing from 20: 00 on March 16th to 20: 00 on March 17th. The depth of newly added snow in the above areas is 3 ~ 8 cm, and the local area can exceed 15 cm.

　　One of popular science reading:

　　How is the meteorological early warning information released?

　　Practice shows that early warning before disasters occur is the key to build the first line of defense for disaster prevention and mitigation. Early warning is not issued at will, it has experienced a life "four-part" of gestation, birth, spread and dissolution.

　　Pregnancy: data collection and analysis "brainstorming"

　　In order to find weather phenomena that may lead to disasters earlier, meteorologists monitor wind (wind, direction), temperature (air temperature, ground temperature, sea temperature), air pressure, humidity, visibility, rainfall (snow), lightning, clouds and many other meteorological elements around the clock.

　　All kinds of meteorological observation data collected are transmitted to the weather forecaster’s work platform and "fed" to the supercomputer. After calculation, a numerical value about the possibility of a meteorological disaster is obtained; According to the calculation results and all-round stereoscopic observation data, the weatherman analyzes weather charts and numerical forecast products at home and abroad, studies various types of weather charts, analyzes and judges the data obtained by various means such as meteorological satellites and radar detection data, and diagnoses the weather evolution; Compare the predicted value with the standard critical value of early warning level set in advance through research, and start issuing the corresponding type and level of meteorological warning when it meets the conditions.

　　At present, there are 14 kinds of meteorological disaster early warning in China, which correspond to blue, yellow, orange and red warning levels according to the development trend, urgency and harm degree of meteorological disasters.

　　Taking rainstorm as an example, issuing a blue rainstorm warning means that the precipitation will reach more than 50 mm in the next 12 hours, or it has reached more than 50 mm and the rainfall may continue; Issuing a red rainstorm warning means that the precipitation will reach more than 100 mm in the next three hours, or it has reached more than 100 mm and the rainfall may continue.

　　It should be noted that due to different regions, the impact of rainstorm warning at the same level will be different. For example, if 100 mm of rain falls in the rainy coastal areas of South China within 12 hours, the impact will of course be different compared with that in the less rainy northwest. Early warning signals shall be subject to those issued by the local meteorological department.　　

　　What do you think of rainstorm warning

　　Birth: the first authoritative voice

　　Every meteorological early warning information "released" must take a "only way", that is, the national early warning information release system.

　　As a part of the national emergency command platform system, the national emergency early warning information release system has set up four levels of early warning information release centers at the national, provincial, municipal and county levels. The public coverage of early warning has reached 87.3%, and the time limit for early warning release has reached 3 to 8 minutes. It can be targeted and sent to the disaster prevention responsible persons in the affected areas within 1 minute, and emergency response can be carried out quickly, making early warning signals truly the first line of defense for meteorological disaster prevention and mitigation.

　　Communication: Multi-channel timely response release

　　In order to improve the coverage of early warning information release as much as possible and realize rapid and accurate early warning information release, meteorological offices and stations affiliated to competent meteorological departments at all levels need to release early warning signals through various channels in time, indicate the areas for early warning of meteorological disasters, and notify the people’s governments at the corresponding levels, their relevant departments and disaster prevention and mitigation institutions.

　　Local people’s governments at all levels and their relevant departments should make a good connection plan after receiving the early warning signals provided by local meteorological stations, such as how the public security traffic police department manages road traffic and how the subway can prevent and deal with stagnant water. In addition, it should be widely disseminated to the public in a timely manner, and early warning signals should be disseminated in a timely manner through television, websites, mobile phones and other media, and the names of meteorological stations and stations that issued early warning signals and the release time should be marked.

　　From the "release" of meteorological early warning information to the affected people, the time left for people to take disaster prevention and avoidance measures is often only a few hours or even dozens of minutes. In this limited and precious time, whether the "last mile" of meteorological early warning information goes smoothly is directly related to the effectiveness of disaster prevention and mitigation.　　　

　　Release: Return to the Whole Chain Management of Disaster Prevention and Mitigation

　　After the release of meteorological early warning information, the weatherman should pay close attention to the development of disastrous weather, continuously observe the data that affect the early warning, and adjust the level of early warning in time. A blue warning may be upgraded to orange or red warning with the passage of time and the change of magnitude. When the disastrous weather process is over, the early warning cancellation message will be released, and the mission of early warning will be completed.

　　The second part of popular science reading:

　　What do you think of "blue, yellow, orange and red"?

　　In our daily life, we can often see meteorological disaster warning signals with different colors on our mobile phones and TV, and everyone is familiar with them. But when you think about it carefully, it doesn’t seem clear about the level of meteorological disasters, the impact and its defense methods represented by each color. Then, what should people do when they see the warning signal issued by the meteorological department?

　　look

　　At present, China has popularized a set of comprehensive methods for the release and dissemination of meteorological disaster warning signals, which consists of names, icons, standards and defense guidelines, and is divided into typhoon, rainstorm, blizzard, cold wave, gale, dust, high temperature, drought, lightning, hail, frost, fog, haze, road icing and so on. Warning signals of different colors indicate different levels. Generally speaking, there are four colors: blue, yellow, orange and red, which respectively correspond to the degree of harm, urgency and development trend that meteorological disasters may cause, and are Grade IV (general), Grade III (heavier), Grade II (serious) and Grade I (particularly serious).

　　Dichotomy

　　From blue, yellow to orange and red, the same kind of meteorological disaster warning signal has different levels, and the corresponding defense measures are also different. When the meteorological disaster warning signal is issued, the public should pay attention to the weather changes in time and make reasonable arrangements for travel. It should be noted that the categories and levels of meteorological disaster warning signals vary from place to place. For example, some areas will be affected by typhoons, while others will not. Some of the same categories are three-level "yellow orange red" and some are four-level "blue yellow orange red". This is because China’s geographical scope is vast, and the types and ranges affected by meteorological disasters vary from place to place. According to the characteristics of local meteorological disasters, provinces (autonomous regions and municipalities directly under the Central Government) can choose or add specified types of early warning signals and set different signal standards. But the same thing is that the higher the warning signal level of meteorological disasters, the more attention the public should pay.

　　Three actions

　　Generally speaking, we should pay attention to travel arrangements when we see the lowest warning signal. For example, when the blue rainstorm warning signal of the lowest level is issued, people should carefully consider the plans of traveling, going out for an outing or going to low-lying areas, and pay attention to the weather changes at any time. With the improvement of meteorological disaster warning signal level, people should make corresponding precautions, and must not "turn a blind eye" or "listen without hearing".

　　At the same time, we can refer to the Measures for the Release and Dissemination of Meteorological Disaster Early Warning Signals to further understand the meteorological disaster early warning signals and related preventive measures, and understand the meteorological disaster early warning signals through the official website of China Meteorological Bureau, Central Meteorological Observatory Network, China Weather Network and other channels. Schools, airports, ports, stations, highways, tourist attractions and other public places will also set up or use electronic display screens and other facilities to spread meteorological disaster warning signals.

　　In normal times, as long as we pay more attention to the weather and understand the meaning behind the warning signals of meteorological disasters, and don’t "underestimate the enemy" at critical moments, our awareness of prevention will be improved accordingly, and the effect of meteorological disaster prevention and mitigation will be greatly improved.

　　CCTV News:As of today (December 28th), the West-to-East Gas Pipeline Project, with a total investment of more than 400 billion yuan and continuous construction for 20 years, has become one of the largest natural gas pipeline systems in the world. Let’s review the development history of engineering in this century.

　　In February, 2000, the country started the West-to-East Gas Transmission Project, which was regarded as a landmark project for the development of western China.

　　On July 4, 2002, the West-to-East Gas Pipeline Project started. On December 30, 2004, the first line of west-to-east gas transmission was put into commercial operation. The first line of west-to-east gas transmission takes Tarim gas field in Xinjiang as the main gas source and the Yangtze River Delta as the main target market.

　　With the increasing demand for natural gas clean energy in the downstream market, the west-to-east gas transmission project was started in March 2005, and the gas transmission capacity was increased by more than 40%. In 2007, the Second West-to-East Gas Pipeline Project was officially launched, and it was put into operation in 2011, transporting natural gas from the Central Asian natural gas pipeline to the central and southern parts of China and the Pearl River Delta region.

　　Since the 18th National Congress of the Communist Party of China, the construction of the West-East Gas Pipeline has been further accelerated. In 2012, the Third West-East Gas Pipeline Project started construction, and fully realized the autonomy of engineering technology and the localization of technical equipment. After completion, it was connected with the original first and second lines, realizing the leap-forward development from pipeline gas transmission to pipeline network gas transmission.

　　This year, the middle section of the third line of west-to-east gas transmission started construction. The annual gas transmission capacity of the west-to-east gas pipeline system has exceeded 100 billion cubic meters, a record high. China has formed a new pattern of "one national network" of natural gas that spans east and west, runs through north and south, and connects overseas.
