Once Upon a Time in Hollywood exposure stills margot robbie retro dress debut

1905 movie network news Recently, quentin tarantino’s new film exposed a stills of sharon tate played by margot robbie. In the stills, Margot·Robbie has shoulder-length blond hair, wearing a high-necked black sweater, a short white skirt and white boots. The overall shape is retro and natural, which is very pleasing to the eye.


Sharon tate was a famous actress in Hollywood in 1960s, who was famous for her beauty and moving. Judging from the newly exposed stills, sharon tate played by margot robbie seems a little conservative. Once Upon a Time in Hollywood told a famous murder case. From August 9 to 10, 1969, Polish director roman polanski was pregnant with actress wife Sharon, who was eight months pregnant.·Kitty, her four friends and the gardener’s son died tragically in a mansion in Beverly Hills. Sharon Tate, a gorgeous Hollywood star; Husband Roman Polanski, a famous Hollywood director, is eight months pregnant because her husband is filming in Europe. Sharon invited four friends to spend the weekend in her mansion in Beverly Hills. It should have been a happy weekend. However, it was their fame that got them killed. On August 9, 1969, Tate’s eight-month-old fetus was strangled alive with her mother. Four friends who spent the weekend at her home were also doomed. What is even more cruel is that they all died bloody and unrecognizable.


In the film, Xiao Li plays Rick Dalton, the neighbor of Polanski and his wife, a former western TV star, and Peter is the star’s long-time friend and body double Cliff Booth, both of whom strive to get ahead in Hollywood. Pacino is Marvin Shwarz, the agent of Little Plum, and this is his first collaboration with Quentin. Margot robbie plays Tate himself, Dakota Fanning plays Lynette Fromme, the notorious follower of Manson’s murder family, and burt reynolds plays George Spahn, who rented the farm to Manson’s family. In order to let Spahn allow them to live on this land, Charles Manson requires all female followers in the family to have sex with the 80-year-old man who is half blind at that time, including Lynette played by Fan Ning. Damian Lewis plays the famous Hollywood movie star steve mcqueen, emil Hesky plays the hairdresser Jay Sebring who was killed in the Tate case, Clifton Collins Jr. plays the Mexican cowboy Ernesto, and Nicholas Hammond plays the Hollywood actor sam wanamaker (). Kurt Russell, TimRoss and michael madsen will also appear in the film, and the roles they play are still unclear.


According to the plan, the film will be made into an R-rated film and will be released on August 9, 2019.

National Development and Reform Commission： CPI rose by 1.7% in the first half of the year, and prices continued to operate within a reasonable range.

Cctv newsOn July 14th, the National Development and Reform Commission held a media briefing on the economic situation in the first half of the year. Wan Jinsong, director of the price department of the National Development and Reform Commission, said at the meeting that since the beginning of this year, international energy and food prices have risen sharply, and inflation in major economies such as the United States and Europe has remained high. In recent months, the consumer price index (CPI) has risen by more than 8%, a record high in the past 40 years or on record. Last night, the CPI in June released by the United States rose as high as 9.1%. However, China’s prices continued to operate in a reasonable range. In the first half of the year, CPI rose by an average of 1.7%, which was significantly lower than that of other major economies, in sharp contrast to the high international inflation.

Wan Jinsong said that the CPC Central Committee and the State Council attached great importance to stabilizing prices. Since the beginning of this year, the National Development and Reform Commission has thoroughly implemented the decision-making arrangements of the CPC Central Committee and the State Council, continuously strengthened the construction of the production, supply, storage and marketing system of important commodities such as grain and coal, and responded to the uncertainty of the external environment with the certainty of domestic supply and stable prices, effectively ensuring the basic stability of prices. In terms of important livelihood commodities such as grain, we will make every effort to stabilize grain production, strengthen regulation and control to stabilize pig production capacity, strengthen the connection between vegetable production and marketing, and do everything possible to ensure the supply and price stability of important livelihood commodities. Since the Ukrainian crisis, China’s food prices have risen by about 1.4% on average, far lower than the increase of 7.5%-9.5% in the United States and Europe. In terms of energy, China has continuously increased coal production and supply, improved the coal market price formation mechanism, guided coal prices to operate in a reasonable range, stabilized electricity prices and energy costs by stabilizing coal prices, and the prices of electricity and gas for residents have always remained basically stable. However, the electricity and gas prices of residents in major economies such as the United States and Europe have risen sharply. For example, in May, the electricity price in the euro zone rose by about 30% year-on-year, and the gas price rose by about 50% year-on-year.

Ministry of Industry and Information Technology： The series of national standards for conductive charging connection devices for electric vehicles were officially released.

　　Cctv newsOn September 7, 2023, two recommended national standards, GB/T 20234.1-2023 Connecting Devices for Conductive Charging of Electric Vehicles Part 1: General Requirements and GB/T 20234.3-2023 Connecting Devices for Conductive Charging of Electric Vehicles Part 3: DC Charging Interface, were officially released.

　　Charging standard is the basis to ensure the interconnection between electric vehicles and charging facilities and the safe and reliable charging. In recent years, with the increase of driving range of electric vehicles and the increase of charging rate of power batteries, consumers’ demand for rapid replenishment of electric energy for vehicles has become increasingly strong. New technologies, new formats and new demands, such as "high-power DC charging", are constantly emerging, and it has become a general consensus in the industry to speed up the revision and improvement of the relevant standards of the original charging interface. According to the development of electric vehicle charging technology and the demand for quick charging, the Ministry of Industry and Information Technology organized the National Automobile Standardization Technical Committee to complete the revision of two recommended national standards, and realized the brand-new upgrade of the original 2015 national standard scheme (commonly known as "2015+" standard). The new standard follows the current technical scheme of DC charging interface in China, ensures the universal compatibility of new and old charging interfaces, increases the maximum charging current from 250 amps to 800 amps and charging power to 800 kW, increases relevant technical requirements such as active cooling and temperature monitoring, and optimizes and perfects test methods such as mechanical performance, locking device and service life, which is conducive to further improving the environmental adaptability, safety and reliability of conductive charging connection devices, and at the same time meets the requirements of low-power and high-power DC charging.

　　In the next step, the Ministry of Industry and Information Technology will organize relevant units to do a good job in the promotion and implementation of the two national standards, promote the popularization and application of technologies such as high-power DC charging, and create a good environment for the high-quality development of the new energy automobile industry and the charging facility industry.

Meteorological bureau： 5 measures to ensure the forecast of increasing pollen concentration in Olympic meteorological service


　　Yu Xinwen, spokesperson and office director of China Meteorological Bureau (photo: Yang Jia/China Net)


　　This afternoon, a press conference on Olympic weather forecast was held in Beijing International Press Center. Yu Xinwen, spokesperson and office director of China Meteorological Bureau, Chen Zhenlin, spokesperson and deputy director of the Department of Prediction and Disaster Reduction of China Meteorological Bureau, Wang Jianjie, spokesperson and deputy director of Beijing Meteorological Bureau, and Qiao Linte, chief forecaster of the National Meteorological Center of China Meteorological Bureau introduced the weather in Beijing during the Olympic Games.


　　Yu Xinwen said that in the past seven years, China Meteorological Bureau has focused on the purpose of "Green Olympics, High-tech Olympics and People’s Olympics" and aimed at achieving "high-quality, high-level" Olympic meteorological services. It has made great efforts to strengthen the capacity building of meteorological observation, continuously improve the forecasting ability and meteorological service level, and made great efforts to make preparations for the Olympic meteorological services. At present, it is progressing smoothly and ready.


　　Yu Xinwen said that the meteorological service guarantee for the Beijing Olympic Games is all ready. We know that meteorological services play an important role in the Olympic Games, and we have mainly done the following work:


　　First, a three-dimensional observation system has been established, forming a relatively strong monitoring capability.


　　After several years’ efforts, the comprehensive meteorological observation system, which consists of four in-orbit meteorological satellites, multiple radars and encrypted automatic weather stations, will be able to capture more subtle weather changes with wide coverage and high temporal and spatial resolution. At present, Fengyun-1 star D, Fengyun-2 star C, Fengyun-3 star D and Fengyun-3 star 01 launched this year will all provide services for the Olympic Games, and satellite cloud pictures can be obtained every 15 minutes. There are 7 weather Doppler radars in and around Beijing, and 3 weather Doppler radars in and around Qingdao, all of which have been built and put into use. The detection data will be obtained every 6 minutes, and two mobile weather radars will provide more comprehensive information. A new generation of weather Doppler radar is built in each co-host city. There are 186 automatic weather stations in Beijing and 167 automatic weather stations in Qingdao, which make the density of automatic stations in the main co-host cities reach about every 5 kilometers in urban areas and every 10 kilometers in suburban areas, and the observation data can be updated in real time every 5 minutes. In addition, an encrypted automatic weather observation station was added near the venue as required.


　　Second, refined forecasting and targeted services.


　　During the Olympic Games, Beijing Olympic Meteorological Service Center will make a daily rolling update of the fine forecast of meteorological elements of Olympic venues for 0 ~ 72 hours and 3 hours. Make a 3-hour forecast of meteorological elements of competition venues for 0-72 hours several times a day. This kind of long-term forecasting service also exceeds the meteorological service requirement of 0 ~ 48 hours in previous Olympic Games. According to the demand of individual events, the meteorological department will also provide hourly forecast service for the next 24 hours, that is, the meteorological department will provide multi-factor forecast every day, which is equivalent to 40 times the workload of the previous meteorological department. In case of major turning weather, such as thunderstorms, tornadoes, hail and other weather that may affect the competition, a 0-2 hour approaching weather forecast will be made and updated approaching forecast information will be released in time. In addition, for Qingdao Olympic Sailing Competition, a refined hourly wind forecast method was specially developed to provide hourly wind speed and direction forecast for four buoy stations.


　　The third is to gather national strength and form an elite team.


　　With comprehensive and rich weather monitoring data and advanced application mode, people have become a key factor. Efficient and powerful command system, practical work experience of forecasting experts and comprehensive analysis and judgment ability will all play an important role. China Meteorological Bureau has set up an Olympic meteorological service leading group headed by the director to direct and coordinate the national Olympic meteorological service. According to the requirements of "Beijing 2008 Olympic Games Urban Operation Outline", a series of meteorological service guarantee schemes, such as "Beijing 2008 Olympic Games Meteorological Service Action Plan", "Beijing 2008 Olympic Games and Paralympic Games Meteorological Service Implementation Plan" and "Olympic Torch Relay Meteorological Service Implementation Plan", were compiled, and the contents, service methods, operation mechanism, service team and emergency meteorological service guarantee measures of Olympic meteorological services were defined. Relying on the Beijing Meteorological Bureau, the Beijing Olympic Meteorological Service Center was established, with the joint participation of the National Meteorological Center, the National Climate Center and the co-host cities, and the National Meteorological Information Center and meteorological departments at all levels provided full support. Elite meteorological service teams were set up from meteorological departments all over the country, and 36 high-level forecasting technicians from meteorological departments all over the country formed a front-line team directly serving the Beijing Olympic Games. The Beijing Olympic Meteorological Service Center also hired 24 well-known domestic meteorological experts from the Central Meteorological Observatory, the National Climate Center, the China Meteorological Research Institute, the General Staff Meteorological Bureau, and the Aviation Meteorological Bureau to assist the Beijing Olympic Meteorological Service Center in providing Olympic meteorological services on-site or remotely. During the Olympic Games,These experts will act separately to provide timely meteorological information services for competitions in various venues. In Qingdao, 10 experts from the National Meteorological Information Center and the meteorological bureaus of Shandong, Beijing, Shanghai, Anhui and other provinces and cities will jointly provide meteorological services for the Olympic Sailing Competition with Qingdao meteorological experts.


　　Fourth, a variety of service means to meet individual needs.


　　In addition to providing meteorological services for various stadiums and competitions, we also actively cooperated with public security, transportation and other relevant departments to provide various meteorological services for urban operation, people’s travel, tourism, etc., and participated in comprehensive support drills. In particular, the emergency meteorological support service for public emergencies has been strengthened. In sudden, turning weather and disastrous weather, we will provide decision-making meteorological services to government decision-making departments in time, providing reference for government departments to arrange various large-scale activities. We have also strengthened the Olympic meteorological service for the public, and timely released early warning information to the public through television, radio stations, websites, electronic display screens in public places (there are more than 8,000 bus display screens), meteorological early warning towers (8), automatic answering platform for meteorological information, SMS (more than 1.3 million users), community broadcasting, community display screens (more than 50) and meteorological information service stations, so as to watch the games and travel for the public. In addition, a weather service hotline 12121 was set up, and the newspaper Olympic Weather Information was distributed to hotels, airports and other public places free of charge. China Meteorological Bureau Network (http://www.cma.gov.cn/), China Weather Network (http://www.weather.com.cn/) and Beijing Olympic Meteorological Service Network (http://www.bjweather.cn, http://www.weather2008.cn) all published English weather forecast information.It is more convenient for foreign friends and athletes to know the latest meteorological service information at any time.


　　Fifth, practice actual combat tests and be fully prepared.


　　Since 2006, China Meteorological Bureau has organized several drills on Olympic meteorological services. Combined with the "Good Luck Beijing" series of sports events in 2007 and 2008, the Qingdao International Regatta in 2006 and 2007, and the Qingdao International Regatta for the Disabled in 2008, we will constantly test the Olympic meteorological service system, train the Olympic meteorological service team, investigate possible problems, and solve the shortcomings exposed in drills and actual combat. In May this year, it provided meteorological support services for the success of the Olympic torch relay on Mount Everest, which was fully affirmed by the Chinese Olympic Committee and the State Sports General Administration.


　　Yu Xinwen said: "At present, all preparations for the Olympic meteorological service are fully prepared. The Olympic meteorological service has entered the state of Games-time service since July 20th, and the China Meteorological Bureau has entered the state of Olympic special work since August 1st. Beijing Olympic Meteorological Service Center provides all kinds of meteorological service products for sports events, large-scale activities, urban operation and public travel according to the requirements of the Games. For sports events, during the 2008 Olympic Games, we will focus on providing Beijing Olympic Games with highly refined venue weather forecast, short-term forecast of sudden weather and early warning information of meteorological disasters. For large-scale events such as the opening and closing ceremonies, we will do our best to provide meteorological services for Olympic decision-making, and provide meteorological monitoring, forecasting and early warning services related to major Olympic events for Olympic organizers, governments and departments in a timely manner; Provide emergency meteorological services for urban operations, especially emergencies; Provide regular weather forecasting services to the public, tourists from all over the world and contestants, as well as "humanized" characteristic forecasting service products such as pollen concentration, ultraviolet intensity and air quality.

Looking at consumption before the holiday ｜ Yuxi, Yunnan： The warm sunshine and savory fragrance in winter start here.

CCTV News:In winter, almost every household in Huaning County, Yuxi City, Yunnan Province will start to make preserved meat. The local favorites are traditional spiced bacon and spicy sausage.

Li Huiqiong, who has made Huaning traditional bacon for more than 20 years, said that the first step to make a good bacon is to choose pork belly with fat and thin and soft taste. Cut the best pork belly into strips, pour a small amount of white wine for disinfection, and then add a proper amount of salt, pepper powder and star anise powder to wipe evenly.

After smearing the pork belly evenly, it needs to be marinated in the container for 2 days. While marinating the bacon, Li Huiqiong began to make sausages. Sausages should be made of hind leg meat, front leg meat or waist plate meat with a little more lean meat and more chewy. According to the ratio of fat meat to lean meat of 3: 7, it is divided into blocks, cut, and then marinated with seasoning. Then prepare the clean casing and pour the meat into the filling machine. In a few seconds, a sausage is quickly filled, tied with a string, and then gently inserted with a fine needle in several places to release excess gas. After more than 10 days, the naturally dried bacon sausage can be ready to serve. As long as it is fried with oil, the bacon is soft and tender, and the sausage is full of chewiness, which makes people memorable.

Laser solid-state synthesis of monoatomic catalyst

Written by | Liu Zhu (University of Manchester, UK)

Description | This article is contributed by the author (research group).

laserIt has always been considered as a very powerful tool for preparing nanoparticles, which can largely replace the traditional hydrothermal or solvothermal methods. In recent years, noble metal nanoparticles prepared by this method have played an increasingly important role in the field of catalysis because of their characteristics of no surfactant and single size.

In order to reduce the use of noble metal catalysts, more and more research has begun to improve the utilization rate of active sites of noble metal catalysts in various electrocatalytic reactions. When the size of nanoparticles is reduced to sub-nanometer or even atomic scale, almost 100% active sites can be fully utilized. However, it is very challenging to synthesize single atoms with the size less than two nanometers by laser liquid phase ablation, because it is difficult to effectively limit the nucleation and crystallization of metal atoms in liquid phase.

Previously, the research group of Professor Liu Zhu from the University of Manchester in the United Kingdom, with Yudong Peng as the main research and development member, has successfully synthesized platinum nanoparticles with a diameter of 2nm on graphene oxide carriers and achieved high-performance electrocatalytic applications. The relevant experimental results have been published in (Advanced Functional Materials, 30, 2001756, 2020）。 In order to further reduce the particle size and achieve the ultimate goal of preparing monoatomic catalysts. Recently, Professor Liu Zhu’s research group reported for the first time the study of laser solid-state synthesis of monoatomic catalysts. In this study, the metal precursor and graphene oxide were simultaneously reduced by laser one-step treatment. The prepared platinum monoatomic catalyst showed ten times higher mass activity than commercial catalyst in hydrogen evolution reaction.

This article uses　Laser solid-phase synthesis of single-atom catalysts　Published for the title in　Light: Science & Applications. The first author of this article is Peng Yudong and the correspondent Liu Zhu.

In this study, they first obtained the graphene oxide film with chloroplatinic acid precursor salt dispersed evenly on the graphene oxide sheet by suction filtration and freeze-drying, and then realized the simultaneous reduction of graphene oxide and chloroplatinic acid by laser irradiation in one step.

Fig. 1 Process diagram of synthesizing graphene supported monoatomic catalyst by laser irradiation.

In order to realize the synthesis of monoatomic catalysts, researchers have studied several influencing factors in the process. Graphene oxide has excellent hydrophilicity, which can make the metal precursor penetrate through the graphene sheet in the process of suction filtration and realize full wetting. The selection of metal precursors is also very important for the synthesis of monoatomic catalysts. In this work, researchers used HP TCL and PtCl? to pretreat graphene oxide respectively. The experimental results show that HP TCL can realize the uniform distribution of precursors on graphene oxide, while PtCl? is easy to aggregate on the carrier. The experimental results show that the electronegativity of metal precursors or their hydrolysates has an important influence on their binding on graphene oxide.

Subsequently, in order to limit the local concentration increase of metal precursors during drying, researchers used freeze-drying to dry graphene oxide pretreated by metal salts.

In order to verify the actual performance of laser irradiation for the synthesis of monoatomic catalysts, the researchers of this research group used 1064 nm nanosecond pulse laser and 355 nm picosecond pulse laser to irradiate the pretreated graphene oxide films at different energy densities.

For the traditional thermal cracking metal precursors and thermal reduction graphene oxide, the reduced metal precursors are easy to migrate and agglomerate on the carrier materials because of the slow process of heating and cooling. However, the high-speed movement of nanosecond and picosecond laser sources can achieve ultra-fast temperature rise and drop and significant photothermal effect. Under this technical characteristic, the movement of reduced metal atoms on the carrier is effectively restricted, and the reduction and graphitization of graphene thin films are effectively realized by laser with 1064nm wavelength. However, the 355nm wavelength laser is difficult to ensure the uniform reduction of graphene oxide films because of its shallow treatment depth and low stripping threshold for carbon materials.

Fig. 2 HAADF-STEM transmission electron microscope image shows isolated platinum atoms dispersed on graphene.

The prepared catalyst showed a low overpotential of 42.3mV when the current density was 10 mAcm in the hydrogen precipitation reaction, and its mass activity was ten times higher than that of the commercial platinum-carbon catalyst.

Fig. 3 The hydrogen evolution catalytic performance of laser synthesized platinum monoatomic catalyst and its comparison with commercial platinum carbon catalyst and similar platinum monoatomic catalyst produced by other methods reported in the literature.

Liu Jiaoshou said that in the process of combating climate change and achieving global carbon neutrality, catalysts are very critical and will play an irreplaceable role in some energy conversion and carbon neutrality reactions. In the field of laser synthesis of new materials, people have been trying to break the size limit of synthetic materials. The fast and universal laser solid-state synthesis method proposed by us at present has created a new record of laser preparation of monoatomic catalysts. It is hoped that this study will provide new ideas for the preparation of monoatomic catalysts and lay some foundations for the realization of roll-to-roll industrialization technologies. We will continue to explore more possibilities of laser technology in the preparation and application of monoatomic catalysts.

JD.COM replaced Xu Lei.

On April 7th, JD.COM issued an important announcement on coaching change. Xu Lei, President of JD.COM Group, succeeded Liu Qiangdong as CEO of JD.COM Group, and will be responsible for daily operation and management, reporting to Liu Qiangdong, Chairman of the Board of Directors of JD.COM Group.

Meanwhile, Xu Lei will join the board of directors of JD.COM Group as an executive director. All appointments take effect immediately.

The founder retired behind the scenes, and the second master took the "No.1 position" on the tooling, which is not a new drama in the Internet circle. Ma Yun, Liu Qiangdong and Huang Zheng, the core founders and leaders of the e-commerce Jianghu "Cat and Dog Fight (Ali, JD.COM and Pinduoduo)", all "retired behind the scenes".

However, JD.COM insiders said that Liu Qiangdong’s resignation does not mean that he is far away from JD.COM’s business, and Xu Lei still reports to Liu Qiangdong. Ma Yun and Huang Zheng, as the founders of the company, also firmly grasp the fate of the company. The "post-wave era" may not have really arrived, but Xu Lei’s internal and external exams have arrived.

Rock Youth at the helm JD.COM: Leading Design 618, taking over the core work of JD.COM began three years ago.

On the morning of April 7th, the news that Liu Qiangdong stepped down as CEO of JD.COM Group rushed to the hot search.

Not surprisingly, Xu Lei, the second-in-command in JD.COM, became the CEO. Xu Lei joined JD.COM Group for more than 10 years. In the eyes of colleagues, he is always less "businessman" and more "rock". It is well known that JD.COM, the "second master" in the Internet circle, likes rock and roll.

According to the observation of the Beijing News Shell Finance reporter, in many public meetings, Xu Lei rarely wears formal clothes. He likes to wear hooded sweaters, "Goro’s" necklaces and "strings", and his social media profile is not business to outsiders. "I never walk in the rain without an umbrella; I have my own sky, and it never rains.

During his tenure as President of JD.COM Group, Xu Lei was mainly responsible for the daily operation and coordinated development of various business segments. Previously, Xu Lei served as CEO of JD.COM Retail, Chief Marketing Officer of JD.COM Group, Head of Wireless Business Department and Head of Marketing Department of JD.COM Mall.

According to the JD.COM Group’s public information combed by the Beijing News Shell Finance reporter, Xu Lei grew up in the military compound and worked for Lenovo Group from 2000 to 2002, responsible for the network promotion of Lenovo Group brands and products; From 2002 to 2007, he worked for Haoye Advertising Network, the largest professional online marketing service provider in China. In 2007, he worked as a marketing consultant for JD.COM Mall, and was responsible for establishing the marketing public relations department of JD.COM Mall; From 2009 to 2010, he served as the vice president of marketing of JD.COM Mall, and was fully responsible for public relations promotion, brand building and government public relations of JD.COM Mall.

In February, 2013, Xu Lei returned to JD.COM Mall as Senior Vice President, fully responsible for marketing. In mid-2016, he served as senior vice president of JD.COM Group, and started to promote the closed-loop integration of front-end businesses and teams such as APP, PC and WeChat in JD.COM Mall, and established the mall marketing platform system.

In April 2017, he officially served as CMO of JD.COM Group, reporting to Liu Qiangdong, Chairman and CEO of JD.COM Group. On July 16th, 2018, JD.COM Mall announced the implementation of the rotating CEO system, with Xu Lei, CMO of JD.COM Group, as the first rotating CEO of JD.COM Mall. On February 1, 2019, JD.COM Mall was upgraded to JD.COM Retail Group, with Xu Lei as CEO.

According to the internal information of JD.COM Group, Xu Lei led the establishment of JD.COM’s marketing and public relations system and platform operation system, which promoted JD.COM’s strategic transformation to mobility. He also led the design of JD.COM 618 marketing activities, and took the lead in opening up JD.COM’s supply chain capabilities. Xu Lei also serves as the director of Dada Group and Everything New Life Group.

Xu Lei’s appointment is not unexpected. On September 6th, 2021, JD.COM Group made an important personnel adjustment. It was announced that Xu Lei was appointed as the president of JD.COM Group, Xin Lijun was appointed as the CEO of JD.COM Retail and Jin Enlin was appointed as the CEO of JD Health Co., Ltd., with immediate effect.

At that time, the Group disclosed that Liu Qiangdong, Chairman and CEO of JD.COM Group, would devote more time to long-term strategic design, young talent training and rural revitalization.

In fact, Liu Qiangdong’s retreat from the background can be traced back to November 2019. After jingdong cloud Computing Company stepped down as a manager, by November 2019, Liu Qiangdong stepped down as an executive of dozens of companies. Xu Lei took over as the legal representative, executive director and general manager as early as 2020, which is the main operator of JD.COM Mall, which is responsible for more than 90% of JD.COM Group’s revenue.

Xu Lei joined JD.COM Group in 2009 and served as CEO of JD.COM Retail, responsible for the development, operation and strategy of JD.COM Group’s retail business. As the most important activity in JD.COM every year, 618, formerly known as the "Black Moon and High Wind" promotion activity in JD.COM, was designed by Xu Lei, and now it has become one of the landmark events in the e-commerce industry every year.

One of the important events that made him lay a solid foundation in JD.COM was that Xu Lei became the CEO of JD.COM Retail in July 2018, established the business philosophy of "value creation based on trust and customer-centered" and led JD.COM Retail to achieve growth for three consecutive years. In November 2019, the financial report of JD.COM in the third quarter of 2019 showed that under the leadership of Xu Lei, the profit rate of retail operation in JD.COM increased to 3.3%, the highest since its initial listing.

Since 2019, Xu Lei has attended many important events in JD.COM, including JD.COM’s secondary listing in Hong Kong and the listing of JD Health and Jingdong Logistics. Xu Lei has replaced Liu Qiang East Station in an important position.

At present, Liu Qiangdong will continue to serve as the chairman of the board of directors, and devote himself to the company’s long-term strategic design, major strategic decision-making, young leading talents training and rural revitalization.

The core management realizes the adjustment of "rank system"

In addition to the latest CEO change of JD.COM Group, Xu Lei was appointed as the president of JD.COM Group in September 2021, the latest major personnel adjustment of JD.COM.

Xu Lei, a former CEO of JD.COM Retail, took the post of group president, Xin Lijun, a former CEO of JD Health, took the post of CEO of JD.COM Retail, the core business, while Jin Enlin, a former general manager of JD Health Pharmaceutical Department, successfully took the post of CEO of JD Health. JD.COM’s core management has realized the personnel adjustment of "ranking system".

However, no matter how other senior management positions change, JD.COM is still under the control of Liu Qiangdong. Insiders in JD.COM said that Liu Qiangdong’s resignation this time does not mean that he is far away from JD.COM’s business, and Xu Lei still reports to Liu Qiangdong.

In the Internet age, the founders of the company have a close relationship with the company. When it comes to Alibaba, Tencent, JD.COM and other people, they will naturally contact the "No.1 position", Ma Yun, Ma Huateng and Liu Qiangdong. In the public psychology, the words and deeds of these bosses have long been linked to the company image.

A management person in JD.COM told the Shell Finance reporter of the Beijing News that in recent years, Liu Qiangdong is still "resolute" and basically participates in the company’s routine executive breakfast meeting at 8 am every day. This breakfast meeting requires all senior executives to participate and has been implemented for more than ten years.

On February 3rd, JD.COM announced that Liu Qiangdong, the chairman of the board of directors of the company, would donate 62,376,643 shares of Class B common stock to a third-party foundation for charitable purposes, and has submitted relevant documents to the US Securities and Exchange Commission. According to JD.COM’s closing price of $73.2 per share on February 2, the donation is worth nearly 15 billion yuan.

However, after this donation, Liu Qiangdong still has control over JD.COM. In April, 2021, JD.COM’s documents submitted on the Hong Kong Stock Exchange showed the latest equity situation of JD.COM. Among them, Liu Qiangdong holds 434.5 million ordinary shares, accounting for 13.9% of the shares and 76.9% of the total voting rights.

Other JD.COM executives Xu Lei, Xu Ran and Zhang Wei hold less than 1% of the common tradable shares. After this donation, Liu Qiangdong’s shares have been reduced to 360 million shares, which is still higher than Wal-Mart’s, and the voting rights are still dominant. Moreover, JD.COM’s internal letter, staff letter and other important information are still issued by Liu Qiangdong.

Can the "New No.1 Position" lead JD.COM through the storm?

Last year, in 618, which is of great significance to JD.COM, Liu Qiangdong issued a shareholder’s letter, saying that in the next decade, JD.COM will devote itself to building a new generation of infrastructure-JD.COM Digital Intelligence Society Supply Chain. The overall development planning and direction of JD.COM Group is still controlled by Liu Qiangdong.

According to JD.COM’s financial report, in 2021, the total revenue of JD.COM Group was 951.6 billion yuan, an increase of 27.6% compared with 2020. Among them, the commodity income was 815.654 billion yuan, an increase of 25.1% compared with the whole year of 2020, and the service income was 135.937 billion yuan, an increase of 44.7% compared with the whole year of 2020.

In fiscal year 2021, JD.COM’s performance turned from profit to loss. Affected by losses for two consecutive quarters, JD.COM’s net loss attributable to common stock in 2021 was 3.6 billion yuan, and its net profit for the whole year in 2020 was 49.4 billion yuan. Xu Lei said at the performance meeting that JD.COM did not pursue the rapid growth of a single indicator, but paid attention to the health and sustainability of the overall business growth.

According to the data of the National Bureau of Statistics, the national online retail sales in 2021 was about 13.09 trillion yuan, a year-on-year increase of 14.1%. Affected by the big environment, the financial report of the e-commerce industry is generally not bright enough. The three sectors that support JD.COM Group’s revenue are retail business, logistics business and new business, among which retail business is still the most important source of revenue, accounting for 91% of the revenue.

The financial report shows that the operating profit of logistics business and new business has turned from profit to loss. The loss of logistics business mainly comes from the first half of the year, because of the strategic investment layout of core resources such as logistics infrastructure, technology and personnel. The new business mainly includes JD.COM production and development, Jingxi, overseas business and technological innovation, and it is also a money-burning business that people in the industry agree. Since the comprehensive transformation to technology in early 2017, JD.COM has invested nearly 80 billion yuan in technology.

However, the sinking market business including Jingxi business has brought a large number of active market users to JD.COM. As of December 31, 2021, the number of active purchase users in the past 12 months was about 570 million, a net increase of nearly 100 million a year, and 70% of the new users came from the sinking market.

In terms of logistics, in 2021, the total revenue of Jingdong Logistics reached 104.7 billion yuan, up 42.7% year-on-year, of which the revenue from external customers reached 59.1 billion yuan, up 72.7% year-on-year, accounting for 56.5% of the total revenue. Jingdong Logistics overfulfilled the strategic goal of "five-year revenue exceeding 100 billion and external customer revenue accounting for more than half" formulated at the time of formal independence in 2017.

In 2021, the customer income of Jingdong logistics integrated supply chain reached 71.1 billion yuan. Revenue growth comes from the increasing number of customers in the integrated supply chain and the improvement of the average income of single customers. In 2021, the number of customers in the external integrated supply chain of Jingdong Logistics increased by 41.7% year-on-year, and the average income of single customers exceeded 340,000 yuan.

Xu Lei repeatedly mentioned at the performance meeting that JD.COM’s logic is to maintain sustainable and quality growth, pay more attention to the quality and refined operation of user growth, and will continue to actively adjust the user strategy. At the same time, he thinks that the ceiling of user growth in JD.COM is still very high, and users will maintain a healthy growth in the next few years, which is very confident.

In the past three years, JD.COM has clearly defined the strategic positioning of "technology and service enterprise based on supply chain". In terms of organizational mechanism, after three years of operation, it has formed a strategic executive committee (SEC) composed of heads of various business sectors and functional systems and a strategic decision-making committee (SDC) composed of dozens of heads of front-line business departments of the Group to make collective decisions and respond quickly.

Obviously, JD.COM is not someone’s JD.COM, but as the president and CEO of the group, Xu Lei will be faced with the reality that the growth of mobile Internet has peaked and how to lead JD.COM’s "brothers" out of the low-profit operation stage and new business difficulties. Not only that, Xu Lei’s internal and external exams have come, and the post-wave drama in the electric business circle is still being staged. While consolidating their own cities, you "post-waves" need to face the rising of external emerging e-commerce places such as Tik Tok and Aauto Quicker.
