It’s been a week since June 18, and when the June 18 war resumed, Juhua, which was fully restarted in March this year, became the biggest dark horse that suddenly emerged. The data shows that during the Tmall 618 period, the cost-effective year-on-year transaction growth reached 86.5%, and the year-on-year order growth was 106%.

　　According to Alibaba, poly-cost-effective led to one-third of Tmall 618 transactions. According to the special report released by the authoritative Internet information service provider Analysys International on June 20th, Tmall’s market share during the promotion period was more than twice that of JD.COM and Pinduoduo combined, and one company accounted for nearly two-thirds of the total market share.

　　The above picture shows the GMV comparison among different platforms very intuitively. The GMV of Taobao Tmall is 100, while that of JD.COM and Pinduoduo is 32.7 and 9.9 respectively. Poly-cost-effective leads to one-third of the transactions, which means that its index of leading transactions reaches 33, which is higher than that of JD.COM and Pinduoduo. More directly, a single gathering is cost-effective, and the turnover during Tmall 618 exceeded three Pinduoduo. In this year’s 618 War, the pattern of the sinking market has been rewritten. As an amoy department, Juhua rushed into the sinking market and gained a lot of advantages in the sinking market.

　　On June 25th, Alibaba "officially announced" the overall growth of Tmall 618. Jiang Fan, president of Tmall, revealed at the launch conference of Tmall flagship store version 2.0 that the physical GMV of Tmall 618 increased by 38.5% year-on-year, and the DAU (daily active user) of mobile phone Taobao also increased by 29% year-on-year during Tmall 618.

　　Caption: Jiang Fan, president of Tmall, was at the launch of version 2.0 of Tmall flagship store.

　　JD.COM did not disclose GMV figures, but the so-called "order amount". According to the figures published by JD.COM, the year-on-year growth of the order amount is only 26.5%, which is 12 percentage points lower than that of Tmall. As the largest e-commerce platform in the whole network, the growth rate of Tmall is also significantly ahead of competitors such as JD.COM. The ultra-high-speed growth of poly-cost-effective has further consolidated the dominant position of Amoy in the whole market.

　　The cost-effective "revival" has also injected important traffic growth into mobile phone Taobao. The year-on-year growth rate of DAU of Hand Amoy is 29%, which is the highest since 2017. It also shows that it is cost-effective to tap the incremental population mainly based on the following heavy market users. Data from traffic monitoring third-party organizations such as Aurora Big Data and Questmobile all show that during the period of 618, the number of DAU (Daily Active Users) of mobile phone Taobao was in an absolute leading position, far exceeding other competitors.

　　Win the sinking market

　　A prominent feature of 618 this year is that "sinking market" has become a battleground for military strategists. In March this year, the comprehensive and cost-effective restart profoundly changed the war situation of 618 this year. Jiang Fan revealed a figure that 49% of Tmall 618′ s purchase users came from the 4 th, 5 th and 6 th tier cities.

　　The research of Aurora Big Data shows that although the penetration rate of mobile phone Taobao in third-tier and below cities is slightly lower than that in first-and second-tier cities, it is still as high as 54.8%, which is significantly higher than that in Pinduoduo (39.5%) and JD.COM (22.3%). It is the only mainstream e-commerce software with a penetration rate of over 50% in third-tier and below cities. The DAU index of Taobao’s sinking market in the third line and below is more than twice that of Pinduoduo.

　　In fact, before the start of Tmall 618, Alibaba began to deploy troops to strengthen the cost-effectiveness. Although Juhua was once an independent business unit of Amoy Department, it was merged into Tmall at the end of 2016. At the beginning of this year, Juhua became independent from Tmall and became a unified marketing platform for Taobao and Tmall, namely the marketing platform business unit. It is also known as Daju Cost-effective business unit.

　　The new big gathering cost-effective covers the core marketing tools of Taobao, such as gathering cost-effective, rushing to buy, selling every day, etc. These business lines occupy almost half of the "half of the country" in the new edition of the hand-scouring six squares.

　　Amoy is one of the most important goals of this year’s 618 strategy, which is to maximize the enthusiasm of users in the sinking market. Alibaba’s "618" this year is "the biggest investment in history" comparable to double 11’s, and the breakthrough has chosen to gather cost-effectiveness. The biggest game of "Ten Million Explosive Groups" is to maximize the marketing explosive power of the poly-cost-effective sale model.

　　According to Alibaba, during Tmall 618, there were more than 180 million transactions and explosions, more than 4,700 million transactions and more than 4,200 items with sales exceeding 10,000 pieces, making it easy to achieve the small goal of "10 million explosion groups and 100 million explosion groups every day". The "Ten Million Explosive Groups" directly promoted the high growth of poly-cost-effective transaction volume. During the period of 618, the growth rate of poly-cost-effective transaction volume reached 89% year-on-year, and the number of users and purchases in third-and fifth-tier cities both increased by more than 100% year-on-year.

　　Jiang Fan said at yesterday’s press conference: "The reason why Juhua can make such progress in just a few months is because it has returned to the original intention of ten years ago, that is, helping consumers find the best-priced goods in the whole network and helping businesses get customers with the most efficient marketing."

　　The best tool for brand customers.

　　Poly cost-effective comprehensive restart, and further become the brand’s best customer acquisition tool. Before Tmall 618, Juhua clearly put forward the goal of "bringing 300 million new customers to the brand", which was finally successfully achieved.

　　This year, 128 brands of Tmall 618 were among the "Billion Club". More than 100 brands such as CPB, L ‘Oré al, Watsons, Dr. Chengye, Telunsu and Peak surpassed double 11 last year, and the sales performance of some brands reached 40 times that of double 11 last year. In this promotion, almost all the brands that became the "Billion Club" participated in the cost-effective activities.

　　As the "biggest investment in history", 618 strives to convey "affordable" mind to consumers. The original price of Dyson hair dryer is nearly 3000 yuan, and 88VIP discount is added to the poly-cost-effective subsidy coupon, and the hand is as low as 1854 yuan. The brand with the original price of 1499 is bigger than an air conditioner, and it will be subsidized after the direct drop, and the hand price is 859 yuan. On June 18 th, Juhua launched the iPhone XR 618 yuan spike, which was less than 10% off the original price, causing the whole network to snap up. The investment of real money has undoubtedly greatly strengthened the influence of poly-cost-effectiveness on the consumer side.

　　Tmall is the brand’s favorite new product release platform. During this year’s Tmall 618, 80% of the core brands released new products on Tmall. With Tmall’s powerful data and operational capabilities, brands can also aggregate consumer information, understand consumer preferences, conduct new product research and development, and create "explosive models".

　　How to make "explosive models" sell better? Tmall has a set of marketing methodology. In Jia Luo’s view, the sale model is a means to help brands reach new customers as quickly as possible. In fact, there is also a very strong demand for branded goods in the sinking market. Brand goods with high cost performance can also "suck powder" quickly once they reach the sinking market. The long-term accumulated ability of Juhua has played a role in this respect. Before Juhua regained its independence from Tmall, it brought considerable business opportunities to the Tmall brand. In 2018, 80% of the brands that participated in Juhua came from new buyers, and the ability of Juhua to "pull new" can be seen. After the further restart, it was cost-effective, and the killer weapon of "Laxin" was used to the extreme. On June 25, the average growth rate of 400 brands participating in the launch of Tmall flagship store was as high as 47% during Tmall 618.

　　Empowering industrial belt to create new supply

　　The data shows that Handamoy has always been the largest shopping APP with the highest penetration rate in China, with more than 700 million consumers on this platform, with rich and diverse needs. How to meet their more and more diverse preferences, Amoy needs to work hard on the supply side.

　　The breakthrough of Tao department selection is still a good deal. In addition to bringing new customers to traditional head brands, Juhua has set its sights on small and medium-sized businesses on the platform. Through their digital transformation, they can provide more high-quality and affordable products, which can meet the diverse needs of consumers and create more business growth for middle-aged businesses.

　　Poly-cost-effective phase of the industry with businesses. In this year’s Tmall 618, a large number of small and medium-sized brands have entered people’s sight through Taobao, such as Yage electric mosquito swatter, Miaoyou children’s socks, Yi Enbei wet wipes, plant protection paper products, Fupai electric toothbrush, and Caramella socks. Although they don’t have the star aura of international brands, they are favored by consumers with high quality and low price. The reason behind it is also very simple. They have entered a cost-effective industrial belt support plan.

　　As a big manufacturing country, China manufacturers have strong production capacity, forming various types of industrial belts such as digital accessories, electric toothbrushes, socks and paper towels. Many industrial belt manufacturers have long been OEM for well-known brands, but they lack their own brands. The daily sale of Juhua’s products fills the shortcomings of industrial belt merchants in operation, technology and brand ability, which can not only help them upgrade their products by digital means, but also solve the sales channels of their goods.

　　On the other hand, when these industries bring merchants to the front desk, many categories of consumption upgrades have successfully reached the sinking market for the first time. For example, the electric toothbrush, a typical "consumption upgrade" commodity, was sold in the sinking market during Tmall 618. Fupai, an electric toothbrush brand in Taizhou, Zhejiang Province, sold 14,051 pieces in one minute after the opening of 618, and sold 400,000 pieces in 16 hours. Juhua cost-effectively pushed the industrial belt merchants and successfully awakened the upgrading needs of consumers in the sinking market. The industrial belt merchants also successfully won 466 million orders during the period of 618.

　　Observing this year’s 618, the strong rise of poly-cost-effective is the most noteworthy phenomenon. To some extent, the battle of sinking market has been rewritten. Juhua Cost-effective, by its own efforts, has driven more transactions than the whole platform in JD.COM and Pinduoduo, which means that it has become the natural choice for users in the sinking market.

　　For consumers, the "cost-effective" mentality has been established, and strong consumer insight and price competitiveness have greatly enhanced the user stickiness of the cost-effective platform. On the other hand, poly-cost-effectiveness has also become the integration of "Alibaba’s commercial operating system", which can effectively empower different types of businesses. The top brands can get more new customers through poly-cost-effectiveness, and the middle-waist businesses can also realize their own product evolution and brand upgrade through poly-cost-effectiveness.

　　The key for Amoy Department to maintain its own competitiveness lies in creating new supply for consumers so as to meet their new demands. And poly-cost-effectiveness is the key link, and it has withstood the test in the 618 War.

　　In the first week of May 2025, 13,478 sets of "Bank" certification statistics were reported. Due to holidays, the number of reports this week decreased by about 12% compared with last week. Among them, 12,087 vehicles (accounting for about 90%, a decrease of about 8% compared with last week) were tested according to national standards, and 7,851 vehicles (accounting for about 58%, a decrease of 12% compared with last week) met the league standard, an increase of about 6% compared with the same period in 2024, and the overall vehicle condition and quality improved.

　　From the uploaded mileage data of vehicle sources, the proportion of "quasi-new car" data of 10,000-30,000 kilometers increased by 1% compared with last week, and the "relatively new car" data of 30,000-50,000 kilometers decreased by 1% compared with last week. The "cost-effective" vehicle source data of 50,000-100,000 kilometers and the "old" vehicle source data of more than 100,000 kilometers were the same as last week, and the quality of data reported this week was improved.

　　Regionally, affected by holidays, except for Shandong, Anhui, Hunan and other places, there was a significant increase compared with last week, and the rest areas all dropped significantly compared with last week.

　　What is bank authentication? "Hang" certification is a certified second-hand car quality information traceability management system introduced by china automobile dealers association based on the national standard "Technical Specification for Appraisal and Evaluation of Used Cars" and the group standard "Technical Specification for Appraisal and Evaluation of Passenger Cars" for all business entities in the field of second-hand car circulation throughout the country. By establishing a unified industry standard vehicle condition traceability mechanism and dispute review mechanism, it helps to build a bridge of trust between second-hand car business enterprises and consumers and effectively protect the legitimate rights and interests of all parties in the second-hand car consumption.

　　BEIJING, Beijing, Feb. 15 (Reporter Kan Feng) It is another school season, and the "school-starting economy" of college students in China is once again hot. In recent years, online consumption, campus express delivery, campus loan and other college students’ consumption phenomena and behaviors have been continuously concerned by the society. So, what is the average consumption level and financial management means of college students? Recently, MyCOS Research Institute released a survey report on the consumption behavior of college students in China.

　　How much can college students spend every month?

　　— — The average monthly consumption is 1212 yuan, boys love socializing and girls love food.

　　The survey, named "College Students’ Views on Consumption and Financial Management", was completed by means of online survey. The survey target was only college students, and a total of 1,289 valid answers were collected from college students in 2016.

　　The survey shows that the average monthly expenditure of college students is 1212 yuan (excluding tuition and round-trip transportation between home and school). Family is the main source of students’ living expenses. 94% of students’ living expenses are provided by their parents or relatives, followed by part-time jobs.

　　Where do college students spend their living expenses? According to this survey, the main consumption chosen by the surveyed boys is social and entertainment, other foods besides basic meals and image consumption, and the main consumption chosen by the surveyed boys is other foods besides basic meals, image consumption and social and entertainment consumption.

　　The proportion of boys spending money on communication/Internet surfing fees (31%) and digital electronic products (16%) is 7 and 11 percentage points higher than that of girls, while the proportion of boys spending money on image consumption (38%) is 24 percentage points lower than that of girls.

　　What do college students mainly look at when shopping?

　　— — Shopping mainly depends on price and quality.

　　It is found that the most important factor for students to consider in shopping is "price", and the second and third places are "quality" and "personal preference".

　　According to the analysis of the report, as a college student class who has not formally entered the society, the source of living expenses is limited, and students pay more attention to price and quality than the brand, grade and advertising of goods when shopping, which shows that most students can spend rationally.

　　With the living expenses in hand, will college students give up their money to "Qian Shengqian"? According to the survey, 57% students have managed their finances in different forms. Among the college students surveyed, 42% chose products such as Yu ‘ebao, Zhaocaibao and Licaitong, 24% chose traditional bank time deposits, and only 3% and 2% bought stocks and invested in P2P online loans. Most students choose a low-risk, robust financial management method.

　　Is the living expenses of college students enough?

　　— — Over 30% of the respondents sigh beyond their means.

　　The survey results show that among the students surveyed, 41% of college students’ living expenses can meet their daily needs and have a balance. More than 30% of college students have made ends meet. According to the survey, 24% of the students’ living expenses are insufficient occasionally, and 8% are often insufficient.

　　According to the analysis of the report, students’ living expenses are not enough. On the one hand, it may be due to factors such as the economic situation of individual families, and on the other hand, it may be due to students’ lack of planning for the use of living expenses.

　　The survey shows that 40% of college students will not plan and arrange the use of living expenses. When the living expenses can’t meet the expenses, 43% of college students choose to give up consumption, while others will choose to ask their parents for help (40%), spend first and then pay (20%) and borrow money from friends (15%) to meet their consumption needs.

　　The survey also showed that 39% of the students surveyed reported that someone around them had used campus loans. The report suggests that colleges and universities should pay more attention to students’ lives, guide students with financial difficulties to seek help and give them help, strengthen risk prevention education, and guide college students to spend rationally and plan their consumption.

　　Time flies, and 2017 is about to close in a blink of an eye. This year, the supervision of the Civil Aviation Administration of China increased, and efforts were made to enhance passengers’ sense of gain; At the same time, technology has empowered the aviation industry, and aviation manufacturing has shown a thriving situation.

　　Looking back on 2017, what major events happened in China’s aviation industry, and what unforgettable moments? Let’s use eight key words together to string together this doomed extraordinary year.

　　Keywords: 1: Big plane

　　The Three Musketeers of the Big Aircraft will gather in the blue sky: C919 will fly into the sky, and the first flight of AG600 will be around the corner.

　　In China aviation industry, domestic passenger plane C919, amphibious plane AG600 and large transport plane Yun -20 are called "Three Musketeers". Each of them embodies the painstaking efforts of Chinese people and carries the dreams and expectations of Chinese people. And 2017 is undoubtedly a bumper year for domestic large aircraft.

　　On May 5th, the domestic C919 large passenger plane made its first successful flight at Shanghai Pudong Airport, which attracted worldwide attention. On November 10th, the C919 aircraft moved to Yanliang, Xi ‘an, and began to enter the next research and development flight test and airworthiness forensics.

　　On December 5th, the AG600 large-scale fire fighting/water rescue amphibious aircraft completed the high-speed taxiing test in zhuhai jinwan airport, and the first flight entered the countdown.

　　Expert comment: C919 is China’s first truly large civil aircraft, a key battle to upgrade China’s manufacturing industry and a landmark project to build an innovative country. China, a large aircraft project, has completely independent intellectual property rights, which not only breaks the monopoly of international aviation giants, but also reflects China’s progress in the field of high-tech innovation.

　　Keyword 2: "Black Flying"

　　UAV "Black Flying" Disturbs Flight Civil Aviation Administration orders real-name registration.

　　With the gradual rise of consumer-grade UAV industry, UAVs have rapidly changed from the original characteristics of "high threshold, strong professionalism and single use" to "low threshold, popularization, multi-function and daily use". According to the statistics of relevant departments, the number of UAVs in China has reached more than 600,000, and it is expected to rise to more than 4 million by 2020.

　　However, due to the increase in the number of drone brands and players, the phenomenon of "black flying" has become more and more serious. Since the beginning of this year, many airports, such as Kunming Airport, Shenzhen Airport, Mianyang Airport, Hangzhou Airport, Chengdu Airport and so on, have been disturbed by drones, resulting in the cancellation or delay of several flights, which has aroused social concern.

　　On May 16th, the Civil Aviation Administration of China issued the Regulations on the Registration Management of Civil Unmanned Aerial Vehicles in real-name registration system, requiring that the owners of civil unmanned aerial vehicles must register their real names from June 1st, 2017. After August 31, unmanned aerial vehicles that are not registered in the system are considered illegal.

　　Expert comment: With the rapid development of civil UAV technology, UAV interferes with civil aviation flight events from time to time. Increasingly strict supervision will promote a virtuous circle of the industry. real-name registration system has opened the prelude to the standardized operation of Chinese drones, and at the same time accelerated the reshuffle of the industry.

　　Keywords: 3: mixed reform

　　The mixed reform of central enterprises continues to accelerate: the three major state-owned airlines have released big moves

　　On the evening of March 27th, China Southern Airlines announced that it had signed a Share Subscription Agreement with American Airlines, and American Airlines would subscribe for 270 million H shares issued by China Southern Airlines with HK$ 1.553 billion.

　　On April 21st, Air China of China announced that it had received a notice from its controlling shareholder, China Aviation Group Corporation, and the National Development and Reform Commission replied that it agreed to reform the mixed ownership of air freight logistics of AVIC. AVIC will start the reform of mixed ownership of air cargo logistics. Air China and some of its subsidiaries are engaged in air cargo logistics business, and the specific implementation of mixed ownership reform may involve the company and its subsidiaries.

　　On June 19th, the mixed reform plan of China Eastern Airlines Logistics Co., Ltd., a subsidiary of China Eastern Airlines Group, ushered in a substantial start. China Eastern Airlines Logistics has diversified its shares. China Eastern Airlines Group, Legend Holdings Co., Ltd., Prologis Investment (Shanghai) Co., Ltd., Debon Logistics Co., Ltd., Greenland Financial Investment Holding Group Co., Ltd. and the core employees of China Eastern Airlines Logistics hold 45%, 25%, 10%, 5%, 5% and 10% of the shares of China Eastern Airlines Logistics respectively.

　　Expert’s comment: In recent years, the freight volume of China civil aviation has increased a lot, but the freight rate has dropped a lot, and the three major airlines have almost no profit margin. In contrast, private express companies such as SF Express, Yuantong and Shentong have set up their own cargo airlines. The global aviation logistics industry is transforming from the traditional air freight with low added value to the door-to-door integrated logistics service provider and the overall supply chain service provider with high added value of "big data+air freight+ground transportation". Through the reform of mixed ownership, the productivity of air freight can be liberated, it can be operated sustainably, and it can be bigger and stronger.

　　Keyword 4: Air WiFi

　　Civil Aviation Administration lifts the ban on aircraft using electronic equipment. Spring is coming in the air.

　　On September 18th, the Ministry of Transport deliberated and adopted the fifth revised Rules for the Examination and Approval of Operation Qualification of Large Aircraft Public Air Transport Carriers. Zhu Tao, deputy director of the Flight Standards Department of the Civil Aviation Administration, said at the press conference that from October, airlines can decide what kind of portable electronic equipment to use on the plane according to the evaluation results.

　　The regulations of the Civil Aviation Administration have triggered a heated discussion on WiFi in the air on the Internet. At present, China Eastern Airlines, Air China, China Southern Airlines, Hainan Airlines and other companies have started to test the on-board WiFi service. For example, China Eastern Airlines has realized the on-board Internet service on 70 wide-body passenger planes.

　　On the morning of October 18th, the MU5103 passenger plane of China Eastern Airlines conducted a live broadcast of the opening ceremony of the 19th National Congress of the Communist Party of China at an altitude of 10,000 meters, and passengers could listen to the speech of the Supreme Leader General Secretary by using WiFi in the air.

　　Expert’s comment: It is a great happy event that the policy completely bans the use of portable electronic devices such as mobile phones on airplanes. However, the release of the policy does not mean that the ban will be lifted immediately. It will take time for the specific implementation, and passengers should not challenge the current regulations of "turning off mobile phones during the whole flight". After the airlines released the restrictions after the safety assessment, passengers could watch movies and listen to music on the "flight mode" mobile phone during the cruise.

　　Keyword 5: Flight punctuality rate

　　The punctuality rate of flights fell into a trough, and the Civil Aviation Administration issued a "ruthless move"

　　As a reflection of the overall transportation quality of civil aviation, the punctuality rate of flights has always been the focus of public attention. Data show that from January to August this year, the average punctuality rate of civil aviation flights nationwide was 66.22%, down 9.27% year-on-year, and the average delay time was 30 minutes, up 11 minutes year-on-year.

　　On the evening of September 21st, the Civil Aviation Administration of China issued "Several Policies and Measures on Controlling the Total Operating Amount and Adjusting the Flight Structure to Improve the punctuality of flights". Starting from this winter and spring season, the total operating amount and flight structure of flight schedules will be controlled to ensure safe operation and fully improve the punctuality of flights. Among them, the Capital Airport and Pudong Airport were punished for failing to meet the standard for many times. The Civil Aviation Administration requires it to reduce the number of departure flights according to the goal of 75% of the airport capacity standard.

　　In October, the normal flight rate in China reached 83.29%, a year-on-year increase of 2.39%. This is the highest normal rate for 101 consecutive months since May 2009.

　　Expert comment: China’s flights maintain double-digit growth every year, but the average annual increase of route mileage is only about 3%, which also makes the flight operation pressure more and more serious. In order to ensure the flight safety of civil aviation and improve the normal flight rate, the Civil Aviation Administration issued the "most stringent" flight control regulations in history to strictly control flight growth. The New Deal officially landed at the end of October, and we expect our flights to be more and more punctual.

　　"Thank the motherland"! Civil aviation chartered flights twice to help stranded passengers return home

　　On September 30th, China tourists trapped by the hurricane excitedly waved the national flag, ready to board a charter flight and return to the motherland. People’s Network Wang Chushe

　　"Thank the motherland for remembering us and taking us home!" This may be the most frequently said sentence by China tourists stranded overseas for some reason this year …

　　On September 18th, category 5 hurricane "Irma" ravaged the Caribbean, and the island country Dominica was hit hard. Nearly 400 Chinese personnel were forced to move to neighboring Antigua and Barbuda to wait for rescue. On the evening of September 29th, China Eastern Airlines dispatched two chartered planes to fly over the airspace of 19 countries to Vere, Antigua and Barbuda, according to the mission requirements of the Civil Aviation Administration of China to send Ming Chuan telegrams. At Bird Airport, the Chinese personnel transferred from Dominica were urgently transported back to China, with a round-trip flight distance of 34,000 kilometers.

　　On November 27th, due to the eruption of Agung volcano, the Indonesian Bali Wulalai International Airport was temporarily closed, leaving 17,000 China tourists stranded there. From 14: 28 on November 29th to 14: 00 on December 4th, the Civil Aviation Administration, the Ministry of Foreign Affairs, the Consulate General of China in Denpasar and other relevant departments coordinated the flights of China Eastern Airlines, Xiamen Airlines and China Southern Airlines to Bali, "coming empty, leaving full" to help China tourists return home.

　　Expert comment: In 2017, Wolf Warriors 2 was popular all over the country, and the scene of Jason Wu holding the national flag through the war zone made countless people excited. In fact, real scenes are more burning than movies. When the storms and waves of nature raze everything to the ground and individuals become so small, the welcome of the motherland is precious and exciting. As the words in the passport at the end of Wolf Warriors 2: "People’s Republic of China (PRC) citizens: When you are in danger overseas, don’t give up! Please remember that behind you, there is a strong motherland! "

　　Keyword 7: Tonnage UAV

　　The world’s first tonnage cargo drone was born. Online shopping or airdrop will come home in the future.

　　On October 26th, AT200, a large cargo drone, completed its first flight at Neifu Airport in Pucheng, Shaanxi Province, and the whole flight lasted for 26 minutes. This marks the birth of the world’s first tonnage cargo drone, and online shopping may be airdropped home in the future.

　　With a total length of 11.84 meters, a wingspan of 12.8 meters, a height of 4.04 meters and a maximum takeoff weight of 3.4 tons, AT200 is the "big guy" in the field of civil UAVs at home and abroad. Its warehouse has a volume of 10 cubic meters and a payload of 1.5 tons.

　　According to the R&D team of the Institute of Engineering Thermophysics of Chinese Academy of Sciences, AT200 is equipped with advanced flight control system and command system, which completely gets rid of the dependence on pilots and realizes the "one-button autonomous take-off and landing" of aircraft in the accusation center. The UAV flight controller only needs to monitor the on-board state, and can change the flight state by simple operation when necessary, which greatly reduces the freight cost and operation difficulty.

　　Expert comment: The AT200′ s short-distance take-off and landing capability has solved the take-off and landing problem of the island’s large-tonnage UAV. By adding the set-point delivery capability later, the aircraft that further improves the delivery accuracy will have broad application prospects in Southeast Asian countries along the Belt and Road Initiative. The shortage of captains has always been one of the main factors restricting the development of China’s civil aviation industry. In order to attract mature captains, some companies even offered a "transfer fee" of 5 million. The first flight of a large cargo UAV will open up new opportunities for the development of China’s civil aviation, especially air cargo.

　　Keyword 8: High-speed rail "forced stop" flight

　　"Air-ground competition" fiery high-speed rail frequently "forced to stop" direct flights

　　On the morning of December 6th, at Chengdu East Railway Station, a CRH3A bullet train stopped at the platform, and a touch of local gold eye shadow was particularly eye-catching. It was the first train D4252 of Xicheng High-speed Railway.

　　In recent years, the competition between high-speed rail and aviation has been fierce, and many routes within 800 kilometers have seen a double drop in attendance and fares, and even been forced to stop. In 2017, "open space competition" was staged again.

　　On April 16th, Zhengzhou-Beijing Sanyi Station went directly to the high-speed railway, and the attendance rate of passengers on the first day reached 80%. The high-speed rail passenger flow between the two places is hot. In contrast, the civil aviation market has shrunk to only one flight.

　　At the end of October, many passengers in Chengdu and Xi ‘an found that the previous direct flights between the two places were basically cancelled. It originally took only one and a half hours, and it took at least six hours after the transfer. Many people in the civil aviation system explained that the Xicheng high-speed railway was opened in October, and the airlines canceled all the direct flights when they made the winter and spring flight plans. Only after the cancellation did they know that the high-speed railway would be delayed.

　　Expert comment: In 2010, China Southern Airlines implemented the "Express Line" strategy to compete with the high-speed rail, which ended in failure. In the future, civil aviation and high-speed rail should compete in a wrong position and win-win cooperation. High-speed rail focuses on the short-and medium-distance passenger transport market, while civil aviation mainly invests in the operation of medium-and long-distance international cross-sea routes. The two sides can also carry out in-depth intermodal cooperation to jointly provide passengers with comfortable and fast travel services.

　　Diaphragm materials are common in our life, such as explosion-proof film on automobile glass and protective film on mobile phone panel. What many people don’t know is that there is also a diaphragm in our mobile phone battery, which is used to prevent the battery from short circuit and transmit ions at the same time. After years of research, researchers of China University of Science and Technology designed a new type of ion conducting membrane. This ionic membrane is expected to be widely used in energy conversion, large-scale energy storage and distributed power generation. The research results were published in the international academic journal Nature on April 26th, Beijing time.

△ Researchers show the new domestic ionic membrane.

　　Ion-exchange membrane is the key component of electrochemical devices or equipment such as flow battery and fuel cell. It should not only prevent short circuit, but also ensure the efficient passage of ions during charging and discharging, and reduce the loss. However, traditional ion-exchange membrane is prone to swelling and deformation after absorbing water, and its structure is loose, especially after being used for a long time, which may lead to structural aging and performance degradation. This kind of new ionic membrane developed by researchers of China University of Science and Technology has solved the problem that ions can’t have both conductivity and selectivity in materials, and the ion transmission is faster, and the near frictionless conduction is realized in the membrane. The charging and discharging current density of the flow battery assembled with this membrane can reach 500 mA per square centimeter, which is stronger than the traditional ionic membrane, less prone to aging, and will not swell due to water absorption.

△ China University of Science and Technology domestic ionic membrane researchers

　　It is understood that for many years, efficient storage and utilization of new energy sources such as solar energy and wind energy has been an important research and development topic for Chinese researchers. The advent of this domestic ionic membrane will break the technical monopoly of similar products abroad for many years, greatly improve the efficiency of energy storage equipment such as flow batteries, and is expected to be widely used in the energy storage field of new energy sources such as solar energy and wind energy in China. At present, researchers are stepping up the mass production of this type of ionic membrane.

　　Professor Xu Tongwen of China University of Science and Technology introduced that we can combine this new flow battery energy storage technology with our power grid for household electricity and industrial production. We can also store the electricity generated by solar energy and solar panels and build a power station to charge cars. In this way, we can save energy and protect the environment, and promote our country to achieve the goal of "double carbon". (CCTV reporter Chu Erjia Wang Shuai)

The tank brand officially released the "off-road+new energy" technical route and the off-road super hybrid architecture. At the same time, two production hybrid models, the tank 300 HEV and the tank 500 PHEV, were unveiled. According to reports, the next tank 700 and 800 models will also launch hybrid models. In the niche hard-core SUV sequence in the era of high oil prices, tanks once again took the lead.

Tank brand This year’s Chengdu Auto Show released the technical route of "off-road+new energy" and the off-road super hybrid architecture, and promoted the new energy off-road as an emerging niche category to enter the public eye. As Liu Yanzhao, CEO of tank brand, said at the press conference, "New energy off-road has become a prairie fire. The new energy utilization of off-road vehicles needs to be based on off-road, and the application of electricity is auxiliary, rather than putting the cart before the horse. "

Therefore, the fundamental of tanks is off-road capability. At this point, the team of the tank brand is deeply aware of where the trigger point of the technical route is. From fuel and hybrid to "electric tank", the tank brand is "one key and three connections".

The off-road super hybrid architecture integrates the core advantages of engine and motor parallel dual direct drive, TOD+ differential lock top mechanical four-wheel drive system, intelligent SOC energy management, etc. It is compatible with outdoor off-road and urban travel, and realizes the full scene coverage of low, medium and heavy off-road.

Based on the off-road super hybrid architecture, the tank unveiled two production hybrid models-the tank 300 HEV and the tank 500 PHEV.

The 300 HEV version of the tank is equipped with a 2.0T Miller cycle engine and a 9HAT transmission, with a maximum power of 224kW and a maximum torque of 640Nm. When driving in the city, the motor is directly involved, and the acceleration of 100 kilometers is within 9s; In the process of crossing driving, the motor can also provide extra power and longer battery life. At the same time, the fuel consumption in the congestion process is greatly reduced by the addition of the motor. In terms of energy saving, the comprehensive fuel consumption per 100 kilometers is as low as 10L under WLTC working conditions, and the fuel consumption can be as low as 9L under urban working conditions combined with an efficient energy recovery system.

The 500 PHEV plug-in hybrid version of the tank is equipped with a battery with an electric capacity of 19.94kWh. With the 2.0T+9HAT powertrain, the maximum comprehensive power is 300kW, the maximum comprehensive torque is 750Nm, and the acceleration time of 0-100km/h is only 6.6 seconds. It can be powered by oil and electricity, and it is strong, quiet and smooth.

The high-efficiency hybrid system can achieve the comprehensive fuel consumption of WLTC of 4.4L/100km and the comprehensive endurance of 736km at full charge. At the same time, the battery system supports 0.5-hour fast charge and 3-hour slow charge, and has 3.3kW external discharge power.

This year, two models, the tank 300 HEV and the tank 500 PHEV plug-in hybrid version, will be pre-sold globally. In the future, 3.0T V6 PHEV products will also be installed on high-end models such as Tank 700 and Tank 800, and will be introduced to the market one after another.

Three drivers’ views:

The data shows that as of July this year, the total sales volume of tank models has exceeded 150,000, and the market share of the hard-core off-road market has reached 56%. As of August this year, the distribution of tank brand channels has covered more than 100 networks nationwide, relying on experience centers, supermarkets, city exhibition halls and delivery centers. It took less than a year for a tank to jump from a model to a brand, and it entered the market with the attribute of online celebrity, but now it needs strong systematic ability to remain competitive.

From 1931 to 1934, Henan University spent three years and more than 210,000 yuan to build a palace-style auditorium.

In the process of construction, builders not only fully consider its safety and firmness, but also take into account its applicability and beauty. Members of the Architectural Committee of the Auditorium and accountants are all "unpaid". With hard work and selfless dedication, they left a permanent public building and an eternal spiritual wealth.

Early Henan University Auditorium

In 1912, on the former site of Henan Gongyuan, Henan Preparatory School for Studying in Europe and America was established. At the beginning, most of the school buildings used in the school were old houses in Gongyuan. In 1919, when Li Jingzhai was the principal, the school built Building 6. The building has a large area, so a lecture hall, the so-called auditorium, can accommodate three or four hundred people. Any assembly will be held here.

Building 6 has long been used as a lecture hall.

In March 1923, the pre-school was renamed Zhongzhou University, "the site of the headquarters is near Caomen in the south, the iron tower in the north, the city wall in the east and the Huiji River in the west." With the support of President Zhang Honglie, Li Jingzhai, director of school affairs, made an overall plan for the campus. From pre-school to university, the number of students has gradually increased, and although the lecture hall is crowded, it can barely be used. In August 1925, Li Dazhao gave a speech here entitled "The History of British Imperialism’s Invasion of China".

Zhongzhou University Planning Map

In 1927, Zhongzhou University was renamed as Henan Sun Yat-sen University after it merged with Henan Public Law School and Henan Provincial Agricultural College. As an auditorium, the lecture hall is still an important place for teachers and students to gather. In the winter of 1929, Fu Sinian gave a lecture in the lecture hall, talking about the development of archaeology and the excavation of Yin ruins. However, the number of students has increased to more than 900, and the lecture hall in Building 6 can no longer accommodate them.

It is extremely necessary to build an auditorium for teachers and students to gather, but it is difficult to raise funds for the construction.

As early as August 1922, under the impetus of Feng Yuxiang and Governor Zhang Fengtai, Henan Province formed a system of using deed tax as education funds and using it independently, and set up a special agency to distribute the education funds in the province. However, wars are frequent, the provincial fiscal revenue is uncertain, and the school allocation quota is difficult to guarantee. For example, in 1927, the fabricated budget was 300,000 yuan, and the school actually received 129,700 yuan; In 1928, the fabricated budget was 255,000 yuan, and the actual income was 227,000 yuan.

It is not easy to maintain school expenses, let alone build an auditorium. The school applied to the provincial government for funds to build the auditorium, but failed to do so. In desperation, the school built a shed as an auditorium and meeting place, which was not only unsightly in appearance, but also could not be used often in winter and summer because of the weather.

The school magazine of Henan University published on September 21st, 1933.

In 1930, the Central Plains War broke out. After defeating Feng Yuxiang, Chiang Kai-shek appointed his lineal Liu Zhi as the chairman of Henan Province. In September, Henan Sun Yat-sen University was renamed as the provincial Henan University. When President Zhang Zhonglu announced the five-year development plan to teachers and students, he was still in the school shed. Soon, Zhang Zhonglu announced his resignation. Zhao Xinwu acted as the principal for only two months, and Li Jingzhai, the provincial director of education, served as the principal for only four months. Principals change frequently, and their tenure is not long, so they have no time to take care of the construction of the auditorium.

Time and cost of building the auditorium

In May 1931, the provincial government appointed Xu Xinwu as the principal, and the construction of the auditorium ushered in a turning point.

President Xu Xinwu

Xu Xinwu studied in the United States in his early years and obtained a master’s degree in hydraulic engineering. After taking office, together with Li Jingzhai, he made adjustments and supplements to the campus planning of Heda University, and put forward suggestions for building the auditorium. At the same time, under the planning of President Xu Xinwu and Dean of Science College Zhao Xinwu, the school added a department of civil engineering, which was approved by the provincial government in June.

At that time, the Department of Civil Engineering was affiliated to the Faculty of Science, with Qu Wenlin as the dean. Qu Wenlin graduated from the Department of Civil Engineering of National Beiyang University (now Tianjin University) in 1921, was appointed as a teacher of Henan Institute of Surveying and Mapping of Water Conservancy Engineering, and took a part-time course in the School of Science of Henan University. The establishment of the Department of Civil Engineering not only expanded the disciplines and specialties of the school, but also provided technical support and talent guarantee for the building auditorium.

The construction of the auditorium was supported by teachers and students, and also by the provincial government. Although Liu Zhi was born in the military, he attached great importance to the revitalization of education during his administration in Henan, especially supported the construction of the auditorium. Later, in My Memories, he wrote: "To raise funds, build the auditorium of Henan University, expand and repair the school buildings of primary and secondary schools, and build the magnificent North China Stadium, in order to seek the initial measures for the development of education in Henan and arouse the joint efforts of local people."

In order to ensure the smooth progress of the project, the school hired Zhang Boying (namely zhangfang, then director of the provincial construction department), Li Jingzhai (then director of the provincial education department), Du Xiu monk (namely Joe Doo, then director of the education fund and production management department) and Qu Wenlin to form the Auditorium Construction Committee, among which Li Jingzhai, Du Xiu monk and Qu Wenlin served as the standing Committee members, who were responsible for design, economy and engineering. At the same time, Yan Shaozhang was hired to be responsible for drawing and project management. Yan Shaozhang participated in the topographic survey of North China Stadium, and was then an engineering professor at Henan University. (See "General Report of the 16th North China Games" published by Shanghai Dadong Bookstore in 1932, p. 101.) As for the positions such as accounting and general affairs, some school staff are concurrently employed.

Profile of auditorium

After intense and detailed planning, on November 20, 1931, the auditorium broke ground. On April 10, 1932, the school held a groundbreaking ceremony. The original construction period was one and a half years, but the project lasted until the winter of 1934. Due to weather changes, uneven materials and other reasons, the project has been shut down for 11 months, so the actual construction period is two years. In more than 750 days, the members and part-time staff of the Construction Committee were "not given jobs", which not only ensured the construction progress and project quality, but also saved a lot of expenses.

Before construction, the construction cost budget is about 140,000 yuan, and the equipment cost budget is about 30,000 yuan. With the consent of Liu Zhi, the Finance Department allocated 150,000 yuan for construction and 24,296 yuan for equipment. In addition, Zhongyuan Company donated 10,000 yuan. These payments, together with the interest generated one after another, total 185,143.18 yuan.

The expenditure on the construction of the auditorium consists of two parts: construction cost and equipment cost. The construction cost is more than 190,000 yuan, and it costs 145,998.817 yuan to buy wood, bricks, limestone, steel and miscellaneous parts. The total number of employees is 73,520, including 21,920 carpenters, 22,600 masons, 25,500 coolies and 3,490 handymen, with a total cost of 45,250.573 yuan. The expenses including steel chairs, electric lights, heating and other materials are called equipment expenses. When the auditorium was completed, only steel chairs were installed, and other equipment was not added, including 12,894.8 yuan for steel chairs, 5,827.8 yuan for transportation and 109.22 yuan for travel remittance. After adding up the construction cost and equipment cost, the actual expenditure reached 210,081.21 yuan.

Qu Wenlin made a detailed analysis of the construction time and expenses in the report. In his view, the reinforcement of foundation engineering, the purchase of steel frames from Britain, the change from wooden floors to reinforced concrete floors, the reinforcement of walls with steel bars and concrete, and the extension of construction period are the main reasons for exceeding the original budget.

The auditorium is sturdy and applicable, beautiful and cheap.

The engineering design of the auditorium is based on the safest standard. In order to ensure the safety of buildings, all materials used are assumed to have the largest external force and the smallest resistance. Although the cost of materials has increased, as a permanent public building, the safety and firmness of the auditorium have been greatly improved. For example, when building the foundation, the designer thought that the terrain of the auditorium was similar to that of Building No.7, but when he dug six feet, he found quicksand and serious water seepage. Designers and constructors use concrete as the lower foundation, and then arrange bricks closely, add mortar, and the foundation brick soil is made of lime, and the size is relaxed, and the load per square foot is calculated according to the worst foundation to ensure safety.

For another example, the auditorium was originally planned to use wooden floors, but for the sake of fire safety, all of them were replaced with steel bars and concrete. The south wall of the venue cannot be thickened due to the bearing capacity of the foundation. In order to ensure the safety, a reinforced concrete beam is added, extending from the east end to the west end and along the east wall to the north, with a total length of 160 feet to support the floor pressure, and 8 reinforced concrete columns are added to support the steel beam.

The interior window area of the auditorium accounts for one-fifth of the venue area, so the light is sufficient. The air capacity in the venue is 400,000 cubic feet, with an average of 160 cubic feet per person. The air is very smooth. In addition, the echo in the auditorium is very small, so you can hear it clearly at the end. Upstairs and downstairs, more than 2600 people can sit in the middle space. The podium, 60 feet wide and 40 feet deep, can hold meetings and plays, and can accommodate more than 200 people. In addition, there are 8 rooms upstairs and downstairs, which can be used as lounge, office, storage room and classroom, each holding 60 people. There are walkways around the venue, upstairs and downstairs for easy access.

Overlooking the auditorium

As the main building of the school at that time, the exterior of the auditorium was in the form of palace architecture, with upper plates in the corners, covered tiles and painted colors similar to those of the palace, while the interior was in the form of modern architectural techniques, with a view to being applicable. From all angles, the auditorium is magnificent and magnificent. Considering the construction cost, the auditorium can be regarded as inexpensive. Qu Wenlin said: "The cost of the Auditorium of Nanjing Central University and the Auditorium of Tsinghua University is nearly 200,000. Although the design of materials and materials are different, our auditoriums are quite unique in terms of beautiful area and solid capacity."

It is reported that Kangzhou Medicine was established in Jiangning High-tech Zone in October 2017. The intimate rent and decoration subsidies in the park, as well as the policy of scientific and technological talents, helped enterprises to save a lot of expenses in the growth stage and attracted biomedical talents with international standards to settle in. At that time, China’s MAH (drug listing permit holder) system had just been piloted for more than a year, and Kangzhou Medicine became the first "listing permit holder under the MAH system" enterprise in the province.

It is understood that before the implementation of the MAH system, only pharmaceutical companies with production capacity are eligible to apply for drug marketing licenses. After implementation, R&D institutions can also apply for drug marketing licenses, and hold their own drug numbers and entrust relevant pharmaceutical companies to produce and sell.

With the help and support of Jiangning High-tech Zone, in 2018, taking advantage of the "east wind" of the policy, three products, namely, Kangzhou Pharmaceutical Atosiban Acetate Injection, Terlipressin for Injection and Carbetocin Injection, were initiated for project research. Among them, Atosiban Acetate Injection, which is used to protect the fetus, advanced the fastest, and was first approved for listing in March 2021. In February and April 2023, it was used to treat complications of liver cirrhosis, respectively.

Ganarik acetate injection listed by Kangzhou Medicine this time is a generic drug of four categories, and it is the second domestic one approved for listing, which is regarded as having passed the consistency evaluation. The drug is a down-regulating drug in the field of assisted reproduction, belonging to gonadotropin-releasing hormone antagonist. It is used in women receiving controlled ovarian stimulation scheme of assisted reproduction technology to prevent premature luteinizing hormone peak. Kangzhou Pharmaceutical Ganarik Acetate Injection is prepared by a new process, which can replace imported products, provide patients with a higher choice of quality and price ratio, and reduce the economic burden. At present, Kangzhou Medicine has established a product line consisting of dozens of products, covering reproduction, digestion, metabolism and other fields, and many products are to be declared.

In the field of biomedicine, Jiangning has more than 1,300 enterprises of various types, covering key areas such as research and development and production of innovative drugs, cell and gene therapy, CRO/CDMO and new medical devices, and has built an industrial innovation system for biomedicine and new medical devices. Biomedical characteristic industrial base was rated as the characteristic industrial base of national torch plan.

At present, Jiangning District is accelerating the establishment and improvement of the "R&D+Clinical+Production+Application" bio-pharmaceutical industry life-cycle ecosystem, and constantly cultivating a number of new enterprises and new products in innovative drugs, high-end medical devices, immune drugs and other sub-areas, and striving to make the scale of bio-pharmaceutical industry account for more than 1/4 in the city.
