Zhang Qingheng feels very proud and honored that the Olympic fire embraces Beijing again. He also looks forward to this “wonderful, extraordinary and excellent” Winter Olympic event. “Although he can’t go to Beijing to watch the game, he also hopes to do his best to publicize the wonderful sports of the Winter Olympic Games and make more people fall in love with ice and snow sports.” According to Zhang Qingheng, the inspiration of this sand painting comes from the theme slogan promotion song MV “together to the future” of the Beijing Winter Olympics. When he saw this MV, he was very happy and excited, so he had the original idea of creating sand paintings for the Winter Olympic Games.

It is reported that Zhang Qingheng spent a total of five days to complete the sand painting work “burning winter Olympics, about ice and snow”, with a total of nine pictures. Yangzi Evening News reporter saw that Zhang Qingheng showed various ice and snow sports such as short track speed skating and figure skating in his sand paintings.

I believe smart babies can immediately see that this is marine Serre. As a fashion brand “born in the sky” in recent years, for a moment, it seems that all trendsetters wear logo moon patterns to attend various occasions, and the pictures of stars are also emerging one after another.

The founder of such a new fashion house, which is “rising to the top” in the industry, is marine Serre, a 29 year old cutting-edge designer. The story of her rise begins with a lost competition.

A talented girl who became a monk on the way

Marine Serre was born in 1991 in a small village in correse, France. She lives with her family. Regardless of her geographical location or family background, she seems to have nothing to do with fashion.

Since childhood, marine has been very interested in fashion and has a special liking for those durable second-hand clothes. She will re transform and cut the ancient works she has found. This creative habit has also planted the seeds for the birth of the brand of the same name.

Marine Serre’s clothes transformed from second-hand clothes

But at this time, her ambition is only in tennis. Her dream is to become a tennis player, so she has achieved good results. In 2004, marine Serre missed the qualification of the French Open, which made her miss the match at the Roland Garros stadium, and then had to rest at home.

During the rest period, marine began to pay attention to the design and transformation of clothes. Due to her previous sports experience, sports elements have become her unique design language, which is reflected in Marine’s future sports hair band and rhythmic gymnastics spherical bag.

Since then, marine became interested in fashion and went to LA Cambre public school in Belgium. In fact, at that time, she knew nothing about the fashion industry, and her passion for clothing was limited to the ultimate love of clothing materials.

During her five years of study, marine went to Maison Margiela, Balenciaga and other brands that thought she understood her ideas. On the other hand, she also rented a studio with only one bed and table and continued to drum up her own brand series.

She later said in an interview, ‘even if you don’t have contacts in Paris, if you really work hard, you will be rewarded’.

This reward surprised her. She just turned 25 in 2017 and won the LVMH prize award from Rihanna.

You should know that this award plays an important role in designers all over the world. Many fashion elites in the industry, such as Virgil abloh, the current designer of LV, Matthew Williams, the current designer of Givenchy and so on, were shortlisted. In the end, she was the youngest and least known.

What made her win this award was her moon pattern full of exotic religious color, which was also her graduation work - “radical call for love”.

What does the moon represent?

When many people first see the moon of marine Serre, they will ask curiously, “isn’t this moon a beautiful girl warrior?”, Some people will also think of Bao Qingtian, who has a black face.

So what does the moon mean? Let’s listen to the explanation of Founder marine. For the mysterious moon logo, first of all, it is one of the oldest symbols in the world. It can be the symbol of the ancient Greek goddess Selene.

Secondly, it also represents Arab culture. The moon is installed on the top of many mosques because it symbolizes rebirth, auspiciousness and happiness.

Therefore, this symbol can be seen everywhere. It can be embodied as many things. Everyone can define it as what you want according to their own ideas. This also represents the tolerance and Aesthetic identity of the brand itself for everyone. The beauty it expresses will never be framed by rules, but lies in the viewer itself.

The moon pattern of marine Serre is actually a variant version of the old flower, which can be known by comparing with the classic Dior oblique old flower. However, although the moon pattern of marine Serre is also distributed in a paved form, the main carrier is not letters, but patterns.

Moreover, from the moment the brand was born, the style of old flowers has been changing. With the release of the new series, new old flowers with various integration trends have been launched. For example, in marine Serre’s autumn and winter 2019 series, the diversity and richness of moon old flower patterns have been fully displayed, and there are all kinds of color matching styles.

In the 2020 spring and summer women’s wear series, the four leaf petal element was added to the moon old flower pattern of marine Serre for the first time, becoming diversified and younger.

In last year’s autumn and winter series, marine Serre began to appear new old flowers dominated by lizard patterns, reducing the situation that the original moon old flower patterns are independent and king.

It is said that it is a brand that likes to collect “junk”

Nowadays, sustainable clothing popular in the fashion industry uses environmentally friendly materials. However, marine Serre directly uses the way of purchasing “garbage” to make fashion, as if the people who buy their clothes are wronged.

In fact, this is the garment making process that the founder has been trying in recent years. The team buys old clothes and then sells them all

Self set threshold for wine purchase

The reporter of Beijing business daily learned from the official flagship store under the 1919 line that due to the large market demand of 53 degree flying Moutai and its long-term short supply, the external price has risen to 1668 yuan. Buying a bottle of flying Moutai can give a bottle of small blue fish everlasting longing for each other dry white wine worth 369 yuan. Since this year, Maotai has repeatedly made a high-profile voice to strictly control the price, requiring its dealers to stick to the 53 degree flying Maotai national wholesale price of 1199 yuan / bottle and retail price of 1299 yuan / bottle. In 1919, as a strategic partner of Maotai, selling Feitian Maotai at a high price obviously ran counter to the manufacturer’s pricing rules.

In this regard, the reporter of Beijing business daily interviewed the internal staff of 1919. The relevant person in charge denied that the stores under 1919 sold Feitian Maotai at a high price, and pointed out that all stores under 1919 sold Feitian Maotai at the price of 1299 yuan per bottle, and the amount exceeding the manufacturer’s price is the price of wine products. Because Feitian Maotai is out of stock and cannot be supplied freely, consumers can only obtain the qualification of Feitian Maotai on the basis of purchasing other wines.

Later, the reporter of Beijing Business Daily called 1919 customer service as a consumer and learned that there are currently two compulsory tying modes for Feitian Moutai, namely, a bottle of Feitian Moutai with a bottle of French little blue fish everlasting longing for each other dry white wine worth 369 yuan, with a package price of 1668 yuan; A bottle of Feitian Maotai with a bottle of baiyinzhuang Cabernet Sauvignon dry red wine worth 499 yuan, the total price is 1789 yuan. The customer service staff also said that this tying mode has been implemented for some time, and many old customers generally place orders directly.

It is worth mentioning that on November 25, the clerk of the official flagship store under the 1919 line said that the packaging price of Feitian Moutai with small blue fish everlasting longing for each other dry white wine was 1558 yuan. Within less than 10 days, the packaging price of Feitian Moutai in the flagship store had soared by 110 yuan. Insiders pointed out that on the premise that the 1299 yuan of Feitian Maotai remained unchanged, the price of the products sold in 1919 rose rapidly. On the one hand, it can be seen that 1919 is draining other products by taking advantage of the heat of Feitian Maotai, on the other hand, it is suspected of raising the price in disguise. Beijing Business Daily reporter also interviewed Maotai on this matter, but as of press time, the relevant person in charge did not respond.

The proportion of Maotai sales fell

The reporter of Beijing business daily learned that the frequent out of stock phenomenon of Feitian Maotai in the distribution channel has become the norm, which also led to a significant decline in the overall sales proportion of Maotai in 1919, which can not form a good support for the latter in the loss reduction. According to the data, in the first half of 2017, the operating revenue of 1919 was 1.705 billion yuan, an increase of 52.55% over the same period of last year; However, the net profit attributable to the shareholders of the listed company is -15.1708 million yuan, and there is still no small pressure to reduce losses. At the same time, in the financial report of 1919, it was highlighted that the sales proportion of Maotai in 1919 decreased from 22.56% in January this year to 7.21% in June this year in the first half of 2017, mainly due to the shortage of goods in Feitian Maotai, and the proportion is still declining.

In July last year, CEO Yang Lingjiang of 1919 pointed out that the sales volume of 1919 is planned to reach 175 billion yuan in the next three years, and the total value of alcohol commodities with a total value of 138.3 billion yuan will be purchased. Among them, circulating commodities and strategic products are an important part of the sales plan for the next three years in 1919. In its three-year total purchase plan of 138.3 billion yuan, the share of circulating commodities is 94.5 billion yuan, accounting for 68% of the total amount, mainly referring to commodities with high brand awareness and good circulation among various categories of commodities, such as Baijiu Wuliangye (68.030, 2.73, 4.18%), Moutai, etc; The share of strategic commodities is 35 billion yuan, accounting for nearly 30% of the total procurement volume. It refers to commodities independently developed in 1919 in addition to circulating commodities, which are used as a supplement to the cooperation with manufacturers in circulating commodities. However, whether it is circulating goods or strategic single products, cooperation with Maotai and drainage of the platform with the help of Maotai brand effect play an important role in achieving the sales target of 100 billion in 1919.

In 1919, he also showed kindness to Maotai many times. In June this year, 1919 apologized to consumers on its official platform for the serious shortage of goods in Maotai, At the same time, he shouted Maotai: “in 2016, the sales volume of Feitian Maotai on the 1919 platform was close to 700000 bottles, about 300 tons. It can be said that 1919 is the largest single retail channel of Maotai liquor. According to the existing growth rate, it may increase three times in 2017, and the sales volume is close to 1000 tons, which puts great pressure on us. I hope Maotai will give appropriate support to make 1919 more effectively ensure product quality.”

However, Maotai’s direct control distribution channels are generally restricted and out of stock, which is difficult to ensure the smooth supply of goods in 1919. The clerk of a Maotai exclusive store on Xiaoying North Road, Chaoyang District once told the Beijing Business Daily that the delivery deadline of 53 degree flying Maotai liquor sometimes exceeds half a month. At present, physical stores are mainly selling other series of Maotai products.

Caixuefei, a Baijiu marketing expert, pointed out that Feitian Moutai is a typical star traffic product. The serious shortage of goods has a great impact on the liquor vertical e-commerce platform represented by 1919, and will also affect the stickiness of some high-end consumers to the 1919 platform.

Game between vertical e-commerce and wine enterprises

“In fact, the compulsory tie-in sale of Feitian Maotai in 1919 was a disguised price increase. Low price sales and high price

At present, the marine culture and tourism city project in the era of navigation is in the construction stage. In the next few years, a large number of excellent college graduates of various majors are needed to enrich the project construction and operation development. At this time, the two sides signed a cooperation agreement to jointly create a high-quality training curriculum system and explore a new teaching mode, which not only conforms to the development direction of the times and industry, but also meets the practical needs of talent training and students’ career development. I believe that through the joint efforts of both sides, we will accumulate new valuable experience for the development of school enterprise cooperation and the integration of industry and learning.

Maritime culture and tourism city in the era of navigation

Dalian navigation times Tourism Development Co., Ltd., established in 2020, is a Sino foreign joint venture focusing on the integrated development of cultural tourism industry chain, the optimization and integration of cultural tourism resources and the R & D, construction and operation of cultural tourism projects.

In the 60th minute of the game, when he saw the substitution card on the side of the court light up his No. 21, de Jong looked obviously angry and left from the other side of the court. Harvey replaced DeJong with Nico.

Harvey’s replacement of De Jong is naturally justified. It may be due to physical reasons. De Jong has been in a low state in recent games. He has no energy on the court and lacks contribution at both ends of attack and defense. In fact, one of the players Harvey criticized after the loss to Cadiz was de Jong.

At present, Derong is still deeply involved in transfer rumors. It is reported that Barcelona hopes to sell him for 80 million euros to ease the economic tension of the club. He is also one of the few players in Barcelona who can sell and sell at a high price. Manchester United are interested in him and tenhah wants to bring de Jong to Manchester United.

“As” said that although Harvey said publicly that de Jong is very important, at present, de Jong is dissatisfied with the current situation and it is difficult for him to reach the peak in Barcelona, Harvey may also consider the possibility of selling him.

Last month, India launched an investigation into the fire, and the government also set up an expert committee to formulate remedial measures. Okinawa has recalled 3215 electric vehicles this month.

India hopes to make the proportion of electric scooters and electric motorcycles in two wheeled vehicles reach 80% by 2030, and now it is only 2%. Ola claimed to support the electric vehicle safety policy. It made a preliminary diagnosis of an electric scooter and found that the fire accident was an isolated event. The recall was only for preventive reasons.

3、 Eight institutional strategies: extreme tearing of disk trend, where to go for a shares?

Jufeng investment adviser: the bank’s military industry strongly protected the market, and the track stocks showed signs of stabilizing

At present, the main factors that suppress the sentiment of A-share investors have changed. From the situation in Ukraine in the early stage, the Fed’s interest rate increase to the domestic epidemic and the slowdown of economic growth, the steady growth policy will provide support for A-shares. The market has just made a second bottom. From the perspective of market style, blue chips that underestimate low prices still have prominent defensive attributes, while growth stocks that overestimate high prices are still unstable factors in the market.

With the development of the times, the importance of data governance and data security become more and more prominent. On July 10, at the blockchain forum of 2021 world artificial intelligence conference, many experts and scholars emphasized the importance of the integration of blockchain technology with big data, artificial intelligence, privacy computing and other technologies around data.

On site of blockchain forum of 2021 world Artificial Intelligence Conference on “connecting the world’s smart manufacturing new cities”

“It is difficult to meet the development needs of the industry only by relying on a single technology of the blockchain. We should put the value of customers first, innovate and integrate many technologies, solve practical problems in business, and become the mainstream trend of the development of the whole blockchain technology.” Jiang Guofei, vice president of ant group, said.

Combining with big data and AI: solving data credibility and Value Mining

Wang Haifeng, senior researcher of Ouke cloud Chain Research Institute, told surging news that big data technology is an effective capture and collection of data, while the growth of AI technology is inseparable from data-based deep learning, and blockchain technology is an important guarantee for data authenticity and reliability. In this sense, blockchain, big data and artificial intelligence will have a strong complementary and symbiotic relationship in the future.

Wang Yunzhen, CEO of Wanxiang blockchain, said in the forum video, “The combination of blockchain and big data not only solves the problem of data credibility from the source, but also ensures data sovereignty. Finally, under the guarantee of sovereignty and credibility, we can effectively mine the value of big data through knowledge map and artificial intelligence, and establish a reasonable business model of data flow.”

In terms of data value mining, Wang Yunzhen said that blockchain + knowledge map can form richer data flow when the data island is opened up. At the same time, it can efficiently organize data, link massive urban data, support fast and efficient query, predict and analyze through AI technology, and nip in the bud.

Jiang Guofei believes that blockchain and AI can open up the whole link service of IP industry. For example, he said, ant chain launched an IP business platform to connect the IP importer with all small businesses of tmall and pay according to the actual usage of goods. The bottom layer of innovation is the integration of blockchain and AI technology to realize the right confirmation, certificate storage, network wide intelligent infringement detection and infringement confirmation on the copyright chain, which greatly reduces the cost of rights protection and promotes the positive flow of copyright.

Combining with privacy Computing: solving the contradiction between privacy protection and data flow

What is the possibility of the integration of blockchain technology and privacy technology?

Jiang Guofei believes that the combination of blockchain and privacy computing can solve the dilemma of data flow. There is a problem that the triangle cannot be satisfied at the same time: the data owner requires strong privacy, the data user requires ease of use, and the intermediate circulation channel needs a certain degree of liquidity. So today, it is difficult to have a solution that can solve all privacy computing problems.

He said that using blockchain technology, ant combines the different needs of the three parties and provides some ways of privacy computing and data flow protection with different intensities from L1 to L4, which can well solve the contradiction between data sharing and privacy protection and ensure the difficulty of data flow. For example, some scenarios allow clear text data flow, but require full-text authorization, audit and traceability. Some data flow involves very strong data privacy, and the strong privacy of data flow should be guaranteed through multi-party secure computing technology.

Wang Yunzhen also pointed out that the zero knowledge proof of privacy computing (which can prove that he is the legal owner of certain rights and interests without divulging information), dynamic encryption and secure multi-party computing technologies ensure the blockchain + based identity system. Based on blockchain and privacy computing, advanced cryptography knowledge can be used to solve the problems of data unwilling to share and data afraid to share in digital cities, so as to realize the availability and invisibility of data value. At the same time, trusted data circulation also ensures the synergy in the dynamic development of government governance, market economy and digital economy, as well as the vertical and efficient processing mechanism and management mechanism, integrates with horizontal and broader social resources, and concentrates all resources on major events such as technological innovation and digital city construction.

Combine with aiot: solve the problems of asset digitization and value transfer

In addition, Jiang Guofei said that the combination of blockchain and aiot (artificial intelligence plus Internet of things) can solve the problems derived from the physical world to the digital world. Aiot helps solve the problem of trustworthiness of the blockchain source, because no matter how the blockchain flows, it also needs to anchor physical assets into the digital world. At the same time, blockchain also helps aiot solve the problems of asset digitization and value transfer.

For example, he said, ant cooperated with Chery to encrypt and link the vehicle information and battery information, so as to realize the credibility of the source of assets and data, and build a mutually trusted new energy vehicle industry cooperation network based on the trusted data, so as to quickly reduce the cost of cooperation. Through the combination of aiot and blockchain platform, the recycling efficiency of new energy vehicles is significantly improved.

Bao Siyu, deputy general manager of Chery holding group and general manager of Chery commercial vehicle company, also mentioned at the forum that cars are gradually transforming from traditional transportation tools to mobile intelligent terminals, which is the commanding point of some new technologies such as AI, artificial intelligence and big data. The online data breaks the information island and improves the ability of rapid decision-making, but it is faced with the problems of data tamperability and data credibility. Blockchain technology can make its data effectively accessed in the ecosystem, share data and ensure the authenticity and effectiveness of data, solve the problem of trust and greatly reduce the communication cost.

“The integration of blockchain technology is profoundly changing the market relationship of industrial cooperation. The wave of digitalization of industrial cooperation has arrived, which will further stimulate the industrial economy to burst out new vitality and release huge dividends of digitalization of industrial cooperation.” Jiang Guofei said.

Every year before and after the Spring Festival, college holidays, migrant workers returning home and holidays, and COVID-19 prevention and control work, the number of blood donors will be greatly reduced, and blood inventory is facing a huge test. The third people’s Hospital of Yunnan Province, as the only provincial-level class a general hospital integrating medical treatment, teaching, scientific research, health management and occupational disease diagnosis and treatment in Guandu District, Kunming, has always adhered to the purpose of serving the people wholeheartedly for many years. While making every effort to save the dead and heal the wounded and relieve the patients’ pain, it has organized and participated in unpaid blood donation activities and various public welfare projects for many times, More than 1500 medical staff extended their arms and gave love, with a blood donation of 400000 ml.

Especially since the outbreak of COVID-19 in 2020, the hospital has always put the health interests of the people in the heart, shouldered the responsibility for prevention and control of epidemic diseases, carried out the charge in front, fought hard in the front line of epidemic prevention, and firmly built a strong defense line for the health of the people, and made positive contributions in the prevention and control of the epidemic.

“The 12th free blood donation activity of medical staff” is the eighth activity held by our hospital in conjunction with Kunming central blood station. Since 2014, 1436 people have participated in the free blood donation activity of medical staff, with a total blood donation of nearly 400000 (actually 395380) ml. as a noble social public welfare undertaking, free blood donation is a red link to convey the truth of the world, It is an important part of building a harmonious society. Said Hou Jianhong, President of the third people’s Hospital of Yunnan Province.

Recently, metauniverse has become a hot topic in the field of science and technology and capital. In the face of the rising popularity of the meta universe, Shi Ke, member of the CPPCC National Committee, chairman of the Jiangxi Provincial Committee of the agricultural labor party and chairman of the Jiangxi Provincial Association for science and technology, said in an interview with China News Agency reporters on the eve of the two sessions that the meta universe will face three major challenges in the process of landing.

The word “metaverse” comes from the two concepts of “metaverse” and “Avatar” mentioned in the American science fiction avalanche. It now refers to the Internet application and social life form of virtual reality integration formed under the promotion of XR, AI, digital twin, blockchain and other technologies. At this stage, the meta universe is still an evolving and developing concept.

As a scientific and technological worker, Shi Ke believes that the meta universe can be regarded as a high-level upgraded version of virtual reality and a highly interactive and interconnected digital virtual world operated by virtual reality with the support of ultra-high technology.

Under the concept of great heat, many places in China release the signal of ahead layout of the meta universe and bring the meta universe into the future industrial development system; Digital technology giants at home and abroad have also made continuous moves and joined the yuanuniverse track one after another.

At the national two sessions, the application of scientific and technological innovation has always been a topic that Shi Ke has paid attention to and talked about. In his opinion, we should treat the meta universe rationally and dialectically. From a technical point of view, the core technologies involved in metauniverse, such as video games, interaction, artificial intelligence, network and computing, Internet of things, blockchain and so on, are the key supporting technologies of digital economy and need to be developed.

Shi Ke also said that metauniverse has a wide range of application fields, which can be applied to many fields such as social networking, intelligent manufacturing, intelligent medical treatment, film and television entertainment, culture and tourism, security and education, so as to make people’s production and life more intelligent, modern and convenient. “Due to the high degree of virtual and real integration of the meta universe, we should also pay attention to the possible negative impact of life in the virtual world on real life.”

According to public media reports, according to PwC’s prediction, the market scale of metauniverse will reach US $1.5 trillion in 2030.

Although the cosmopolitan industry is still in the “sprouting” stage, it still has a broad prospect.

Shi Ke noted that metauniverse will face three major challenges in the process of industrialization: first, many government officials, entrepreneurs and scholars lack corresponding knowledge and ideas about metauniverse, and their understanding of it is not accurate and comprehensive enough, resulting in unclear what metauniverse is and how to start and develop; Second, China’s existing meta universe core technology can not meet the demand, and there is still a gap between domestic technology and products and foreign countries; Third, at present, a complete meta universe industrial chain has not been formed and economies of scale have not been formed.

In this regard, Shi Ke suggested organizing lectures and training on metauniverse, guiding entrepreneurs, government officials and scholars, and encouraging and helping existing metauniverse enterprises and future metauniverse practitioners to develop real metauniverse technologies and products; Research and develop the core technology of the meta universe to meet the needs of the meta universe industrial chain and the forefront of common science and technology; Gather relevant high-quality resources across the country, introduce foreign yuancosmic leading enterprises and leading technologies, and build a world yuancosmic technology and industrial highland.

In view of the “chaos” of the meta universe, there have been all kinds of chaos of hype and illegal fund-raising under the banner. Shi Ke suggested that in order to achieve the healthy and sustainable development of the meta universe, it is necessary to guide and manage at the levels of industry, technology, law, morality and ethics.
