　　Everyone can create their own map! Autonavi recently launched a new feature of DIY map, which allows users to mark multiple locations, customize self-driving travel routes, and support multiple people to build and share with friends. DIY map is a re-interpretation of Autonavi’s new brand value proposition "Autonavi map, familiar everywhere", which further meets the personalized map needs of sub-groups and specific scenes.

　　Focusing on map services for 19 years, Autonavi has now built a map covering the national road network information and a large number of POI points of interest. But in many scenarios, what people need may not be a standardized map, but some specific places that carry their interests, work needs or precious memories. For example, honeymoon trips, self-driving tours, motorcycle runs, photography spots that can produce photos, drone release points, driver toilet maps, takeaway rider food delivery maps, etc.

　　"Using Autonavi’s proven mapping technology capabilities to provide a tool that allows everyone to easily mark places or routes and create a unique map, that’s what we designed DIY maps for," said Autonavi’s head of mapping related products.

　　Now, users can use the latest version of Autonavi map and click on the "Messages" tab below to see the "My DIY Map" entrance. Click "Mark Location" to add any location in the map, and you can also fill in personalized names, descriptions, pictures and mark colors. Users who like self-driving tours click "Make Directions", and they can easily customize the tour route according to the guidance. After submitting, this information will be visually presented in the DIY map.

　　"Before, every time I organized a self-driving car, I was very tired. I always had to explain the route to friends who had never been there, and the communication cost was very high. Now that I have the Autonavi DIY map, I will send the planned route to the group in advance. Friends can directly see the route itinerary, route points, scenery photos and other information, which is very convenient."

　　Mr. Pang is a delivery stationmaster of a takeaway platform, and he has encountered some difficulties in managing new riders. "In the early days of the station, new riders always encounter the problem of not being able to find the building number, and many times they get bad reviews because of this. Later, I learned that you can use the Autonavi DIY map to mark the uncommon building number, so I took the rider to make a delivery map near Wangjing. There is a building number, and it will also mark the entrance and exit of the community and the repair point. Now our newcomers are no longer afraid of being unable to find a place for food delivery!"

　　Maps and location are one of the most frequently used internet services. With the popularization and deepening of digital life, people’s needs continue to expand. To this end, Autonavi Maps has continued to strengthen product technology innovation in recent years. It is the first company in the world to launch lane-level navigation services on mobile phones. It is the only company that supports both AR driving navigation and AR walking navigation. It has innovatively launched traffic live and DIY maps, which continue to enhance the professionalism of map services and the breadth of people covered.

1905 movie network news "Listen to me, buy it!"

　

Hu Ge and Lei Jiayin, the lead actors of He, were guests in the live stream of Internet celebrities to promote the movie and sell tickets.

Rejiasound sumTang WeiBring "The Whistleblower" to interact with netizens live

　

"The Wild Goose Lake" sold as many as 255,000 movie tickets online, courtesy of "Lipstick One" Li Jiaqi.

The Wild Goose Lake crew sells tickets online

In addition to the online roadshow mode of live streaming and selling movie tickets, these two new films are also "the same family" in terms of creation.

　

Needless to say, the stories are all crime themes, and Xiao Dianjun also saw a deeper doorway between them.

After the debut of "The Wild Goose Lake" in Cannes in May this year, many foreign media gave high praise:

　

"This is a vibrant, poetic and unique Chinese film noir"; "Classic film noirs like’You Only Live Once ‘and’Escape at Night’ can’t help but come to mind"; "Suddenly it feels like China is the best place in the world for film noir"…

　

After its domestic release, many viewers, like foreign media, also used a word – "film noir" when evaluating it. And "The Whistleblower" also has a vague "film noir" flavor.

　Douban netizens evaluation

What exactly is "film noir"? Is it black and white? Black humor? Or is the whole story very "dark"?

　

In fact, "film noir" that took root in Hollywood is growing savagely on the Chinese mainland, combining with various different genres to form a new look. How to say it? Xiao Dianjun will popularize it for everyone.

What is "film noir"?　

The term "film noir" was coined by the French in 1946, and French critics noticed a worldwide concentration of films with similar styles and patterns beginning in the early 1940s.

　

These films are often adapted from detective novels, and most of them depict dangerous crime stories in cities, full of gloom, anxiety, despair, horror, and a sense of compassion and destiny.

"Daybreak."andThe Maltese Falcon

　

The French say that Marcel Carney’s "Daybreak" was the first film noir, while Hollywood considers "The Maltese Falcon" to be their first film.

　

But in any case, the well-known emergence of film noir has created a dynamic and explosive golden age in the history of Hollywood cinema.

　

Similarly, in the field of European film, there have also been a series of film noir masterpieces such as this one.

Classic film noir The Third Man

　

So why are these movies called film noir?

　

The screenwriter Paul Schrader has listed seven common features of film noir for everyone, which are also their common techniques:

　

Most of the scenes are set by night.

(Photographic composition) preferring diagonal and vertical lines to horizontal lines;

Provide equal lighting intensity for actors and sets.

The tension of the composition takes precedence over the physical movements of the actors.

An almost Freudian attachment to water;

A preference for romantic narratives.

Frequently use complex chronological sequences to enhance feelings of hopelessness and the passage of time.

　

So much so that, in short, the first five are about visual style, while the last two focus on narrative characteristics.

The shot in "Beauty"

　

Film noir is first and foremost a very intense and highly stylized visual system.

　

In layman’s terms, most of the scenes take place in the city’s empty streets at night or secret meeting places such as stations and docks, and are often accompanied by special weather such as rain and fog.

　

The protagonist often hides in dark shadows, usually strengthening one side of his face with side light, while the other side is always obscured by the shadows of doors, windows, pillars, railings, and other objects.

　

The shooting angle is often tilted and unbalanced, creating a sense of mystery and alluding to the protagonist’s sense of both good and evil and his inner unease.

The year of birth.

　

Before "The Wild Goose Lake", there were a few domestic films that used these iconic visual elements of film noir, including director Xie Fei’s "Birthday Year", Zhang Yibai’s, Ning Hao’s, and Diao Yinan’s.

Director Diao Yinan has always insisted on transplanting Western noir films to China. Although he currently has only four directorial works, the visual temperament of noir films is stronger than ever.

In "Fireworks by Day", the northeastern towns are under continuous rain and snow, and the streets are dim, with contrasting lighting, forming a very cold and oppressive atmosphere.

The Wild Goose Lake is the culmination of his film noir style.

　

It is understood that the film has a total of 106 scenes, 71 of which are night scenes, accounting for 80% of the entire film.

　

During the humid rainy season in Wuhan, Zhou Zenong, played by Hu Ge, ran from the station to the narrow alley and fled all the way, flashing with rain.

Movies also use shadows to make a big fuss.

The camera will take pictures of the body reflections of Hu Ge and Gui Lunmei on the wall.

From time to time, their faces would be obscured by shadows, flickering.

When they were in the showroom, the multi-faceted mirrors seemed to be inspired by film noir.

Hu Ge and Gui Lunmei around the mirror

"Miss Shanghai" classic scene

According to these visual standards, "The Wild Goose Lake" can really be called the first typical film noir style in the Chinese mainland.

Can’t live without "femme fatale"!

　

If there were no "femme fatale", it would not be a film noir.

　

The female protagonists in the film noir are both beautiful and intelligent, but also as active and strong as men. They are mysterious and always fascinate the male protagonist and follow them around.

　

They will quietly emerge from the shadows in gorgeous evening gowns, revealing their thighs; they will carry out secret operations with guns and cigarette packs. Their faces and guns are enough to "kill".

Classic film noir"Beyond the Vortex"

　

Simply put, they are "scheming" people.

　

If you are not familiar with the film noir of the last century, you must have seen this scene of Rebecca Ferguson there. This is also a film full of retro vibes of film noir.

Mission Impossible 5

　

The women in film noir are usually at the heart of a conspiracy.

　

They only care about themselves and will obtain money and benefits through improper means, often at the cost of death or submission.

　

The male protagonists are mostly tough detectives or policemen, and they will have some obsessive-compulsive disorder. Under the temptation of "femme fatale", they are deeply involved in an unsolvable case, fighting for one thing to the end, and may not understand what happened until the end.

"Chinatown."

　

Film scholar Jan D’Amico once summarized the emotional relationship and plot development of the male and female protagonists in film noir:

　

"Whether a man is destined to act by chance, or because he is employed by a man to deal with a woman, their life experiences fill them with blood and pain at times. When he meets this woman who is not innocent and has the same outlook on life, he is sexually attracted to her, and he is doomed…"

　

So, aren’t "The Wild Goose Lake" and "The Whistleblower" just like that?

　

The characters and fates of the male and female protagonists all conform to the above-mentioned film noir narrative routines, which are simply the same.

Zhou Zenong’s wild and vicissitudes of life, and his taciturn chivalrous temperament is like coming from Melville’s film noir. In the film, he is destined to have only one cause or ultimate purpose – to leave a bounty to his wife while fleeing.

　

But in the process, he meets Liu Aiai, the "swimming girl" played by Gui Lunmei. Liu Aiai is both his helper, attracting him, and "betraying" him, which brings him to the end.

"Femme Fatale" is also often the target of male investigators in film noir, becoming the key to solving crimes. This is the relationship between Liao Fan and Gui Lunmei in the film.

In "The Whistleblower", Lei Jiayin plays Ma Ke, who was originally a winner with a successful career and a happy family. When he met his ex-girlfriend Tang Wei, he began to get confused and suffer a bad luck.

Tang Wei brought him from Australia to Africa, causing him not only to be hunted down by killers, but also to face the situation of his wife being separated.

Even though she was so confused that she didn’t know the truth of the case, Lei Jiayin still followed her to the end of the world like a "big silly boy".

On the way, Tang Wei ruthlessly betrayed Lei Jiayin for his life-saving money, and the "selfishness" of "femme fatale" was on full display.

　

Although "The Whistleblower" is unlike "The Wild Goose Lake", it does not have any shadow of film noir in terms of screen styling, but the overall characterization and plot mode are written in full accordance with the template of film noir.

The two male protagonists played by Hu Ge and Lei Jiayin also have something in common. They both have the moral ambiguity of male characters in film noir, but they have a sense of justice.

Zhou Zenong is the small leader of the theft gang, and Ma Ke is the "scum" who cheated on his ex, but in the end, they all became "heroes" in a sense:

　

Zhou Zenong goes to great lengths for the happiness of his wife in the second half of her life and pays for love; Ma Ke bravely reports the trade conspiracy and corruption of overseas companies, becoming an unsung hero who saves a city.

　

"Film noir" is growing savagely in the mainland

　

Film noir was born during World War II and the Cold War, a time when the American dream was falling apart and society was rife with insecurity.

　

After that, from "Chinatown" to the emergence of new film noir, it has given more new connotations and new styles, but the essence remains the same.

Neon color

　

When film noir arrived in China from the Western world, many changes took place.

　

From "Fireworks in the Day" to "The Wild Goose Lake", especially the latter, there are a large number of street scenes, squares, archways, motorcycles that are unique to China…. The neon lights of the city at night are combined with the special scenery on the edge of China’s urban and rural areas to form a unique and beautiful heterotopian world, full of charm.

Traditional film noir often has a "misogynistic" stance, and the image of "femme fatale" is very rigid and symbolic, but in "Southern Station" and "The Whistleblower", both Gui Lunmei and Tang Wei have atypical female images of film noir.

Guilun magnesium has a tan, freckles on her face, and her body is completely shriveled and weak.

Tang Wei’s overall style is simple and capable, and most of the time it is not sexy on the screen. Only when he meets Lei Jiayin for the first time and escapes for the first time, it shows a bit of beauty.

　

In addition to their appearance, these female characters are also brighter and warmer. They all complete their self-redemption by reversing at the end of the credits.

The visual and narrative elements of film noir are also gradually merging with domestic genre films to create new forms.

　

In "Southern Railway Station," Hu Ge’s characters and action scenes are designed along the lines of martial arts films, and the larger narrative theme of "The Whistleblower" is the mainstream melody with Chinese characteristics.

"Crazy Stone"

　

Ning Hao’s "Crazy" series introduces black texture into local humorous comedies, and also pays more attention to the little people at the bottom; Guan Hu uses absurd fables to express black themes; Cao Baoping creates a black suspense spirit in the context of social reality.

"The Sun Is Burning Heart"　

"I have always been interested in the changing human nature of film noir," said Mr. Diao, who believes that film noir allows directors to think about society and humanity, and that China’s development has provided a natural soil for the creation of film noir.

　

Using the mode of film noir, we can produce works that are both interesting and expressed by the author. This genre is also broadening the development space for domestic art films.

There is a cloud made of rain in the wind.

　

"Fireworks in the Day" earned over 100 million at the box office that year, breaking the curse of the dismal box office of the literary film theater chain and becoming the highest-grossing literary film at that time. With the help of film noir and a cast of stars, Lou Ye successively shot "Clouds Made of Rain in the Wind" and entered the public eye.

The Lyceum.

　

As the aesthetics of domestic audiences become more diverse, the overall market and film industry become more mature, and film noir also provides a stage for new directors to enter the commercial mainstream.

"Violent Silence" is everywhere. Among them, the story of "Earth" is a typological framework of the detective and the "femme fatale" falling in love, which Bi Gan also described as a romantic "black fairy tale".

No matter what the outcome of this film is, it is precisely because the story of film noir is inherently commercial, and with the help of the late "New Year’s Eve" marketing promotion, it can quickly ferment at that time and directly attract the general public to the cinema.

"The Last Night on Earth"

　

Film noir stimulates the imagination of film and creates infinite possibilities. It is both genre and art; both commercial and author; both mainstream and independent, which can open up the "two veins" of film creation.

　

As Shen Qian, the producer of "The Wild Goose Lake", observed and judged: film noir may be the trend of Chinese film in the next few years, not only because of the industry ecology, but also because this type of film happens to be an effective bridge between the author’s expression and the market.

　　　 On the 22nd, the legendary war of ancient costumes that brought together Cecilia Cheung, Ren Xianqi, Zheng Peipei, and Liu Xiaoqing released the single-person version of the promotional poster starring Cecilia Cheung Ren Xianqi, and at the same time exposed a group of Mu Guiying (Cecilia Cheung) and Yang Zongbao (Ren Xianqi). It is reported that these two sets of military costumes show the changes in the identities of the two before and after marriage. Different styles and types of military costumes carefully analyze the emotional experiences of the two, adding a lot of warm pictures to the film.

Cecilia Cheung and Ren Xianqi Posters Exposed

　　　 As the male and female No. 1 in the film, the film specially designed the single-person promotional posters of Mu Guiying and Yang Zongbao. Similar to the style of the posters of the previously announced series of characters, they all use cool-colored backgrounds. Cecilia Cheung and Ren Xianqi went into battle in military uniforms. Ren Xianqi held a long spear in the poster, full of heroism; Zhang Cecilia galloped on her horse, looking anxious.

　　　 In an interview, the director, Chen Chengqi, revealed that he had deliberately increased the love scene between Mu Guiying and Yang Zongbao in the script, and cleverly combined the theme of "the righteousness of the family and the country" with the theme of the two. The movie’s promotional song "Raising Eyebrows" sung by Zhao Qianyu also fits this love theme and was selected. Therefore, when the film is released, Cecilia Cheung and Ren Xianqi "kiss goodbye" will definitely make many female audiences cry.

Cecilia Cheung and Ren Xianqi are deeply in love, lighting up the literary and opera part

　　　 The film is based on the well-known legend of the "Yang family general". Cecilia Cheung and Ren Xianqi play the classic legendary couple Mu Guiying and Yang Zongbao in the film. Although the main plot of the film is to focus on the interpretation of Yang Zongbao, played by Ren Xianqi, after all the men of the Yang family died in the battlefield, She Taijun led the female general of the Yang family to carry the flag of the Yang family and hold on to the battlefield in the case that the reinforcements could not arrive in time; Mu Guiying, played by Cecilia Cheung, led the battlefield many times to rescue everyone in difficult times. However, in order not to let the audience keep indulging in the tragic emotions of the war, the director revealed that he specially increased the love scene of the Mu and Yang, revealing a little warmth.

　　　 It is reported that in the film, Yang Zongbao leads the Song army to encircle Mu Kechang and meets Mu Guiying. From meeting and knowing each other to staying together, Mu Guiying and Yang Zongbao can be regarded as "happy enemies". The romantic emotional drama is integrated with the point of firmness and toughness, which is interspersed throughout the film, making people see the warmth of the war drama. Director Chen Chengqi also said that "Jackie Chan was also moved by the literary drama after watching the first cut of the film."

Husband and wife photos are exposed to reveal emotional experiences

　　　 In order to show the different stages of the film "Women General Yang", Yang Zongbao and Mu Guiying have two military costumes to match, showing the state of each stage.

　　　 Unlike the earlier photos of military uniforms, this time’s military uniforms divide the storyline in a simple and clear chronological order. The film returns the time to the scene where Yang Zongbao and Mu Guiying first met by flashback montage, and then constantly flashes the sweet and bitter moments they experienced together. The director said that "this scene cannot be regarded as the core of the film, but it is very similar to the relationship of some young people in real life. In fact, it is a very heart-wrenching relationship, and everyone will naturally understand when they see the film."

　　　 Regarding the difference between the two sets of armor, Director Chen also introduced, "When Mu Kezhai and the Great Breaking of the Tianmen Formation, both of them were very young and had not yet married, so Mu Guiying’s armor was brighter in color, embellished with bright yellow and red, and Yang Zongbao’s armor had a white decorative pattern with water patterns. When the two came of age and fought in the Western Xia Dynasty, the metallic color of the armor was heavy, Mu Guiying’s pattern was similar to that of Liu Xiaoqing and other female generals, and Yang Zongbao’s armor used many tiger head patterns to show their mature identities."

　　A few days ago, Guangxi University of Foreign Languages issued the "Notice on Not Allowing Disposable Tableware and Lunch Boxes to Enter the Campus", which caused a heated discussion on the Internet. The notice said that starting from November this year, in order to strengthen the food safety management of students, the school will ban takeaway, disposable lunch boxes and plastic bags from entering the dormitory.

　　As soon as the notice was released, it immediately triggered a heated discussion on the Internet, and there were many different voices on campus. Some students believed that the school cafeteria had problems such as crowded space and long waiting time for meals, which could not meet normal dining needs. Prohibiting takeout and packing boxes into the dormitory would bring inconvenience to study and life. Some students said that everyone was used to ordering takeout, and it was difficult for the school to control it.

　　The school said in a statement released later that the move was mainly due to considerations such as environmental protection, food safety and school teaching order. The food safety of takeaway food is not under the supervision of the school, and some food that does not meet the hygiene standards flows into the school with takeaway food, posing a threat to the health of students. At the same time, small vendors carry takeaway food in and out of the campus at any time, which not only affects the teaching order of the school, but also is not conducive to the establishment of a good school ethos.

　　It is understood that in recent years, campus food delivery has developed rapidly, and various conveniences and preferential conditions have attracted a large number of students. At the same time, there are also many hidden dangers in the delivery of food into the campus. School administrators are very troubled by the news that students have food poisoning after eating food delivery and the theft of food delivery staff.

　　In fact, before Guangxi Institute of Foreign Languages issued the notice, some institutions such as Jiangxi Nanchang Institute of Technology had already issued relevant regulations on the management of takeaway food, and everyone had mixed opinions on this move. How to standardize the management of takeaway food into the campus and balance the interests of all parties still needs to be explored.

　　■ Collision

　　Blindly prohibiting will be more "blocking"

　　I have been ordering takeout for lunch and dinner since I was an undergraduate. At that time, the takeout industry was highly competitive and there were many discounts, which could satisfy our demand for delicious food at lower prices. Now suddenly banning takeout from campus is "adding to the blockage" of students. What’s more, as long as the convenience that takeout brings to students still exists, it is difficult to ban it. If it is violently stopped, the merchant may continue to operate in a covert way, so the potential hidden dangers are still difficult to eliminate, but it increases the difficulty of management.

　　2017 graduate student of Guangxi University of Arts, Wang Hengyu

　　Campus ban on takeout is legally binding

　　From a legal point of view, universities and some private communities have the right to establish some rules and regulations to prohibit outsiders and food from entering their management scope, which does not restrict the freedom of students and residents. Especially when it comes to food safety, environmental protection and other matters related to personal and property safety, relevant schools and communities have the right to take necessary measures to protect them. Schools have the responsibility to ensure the safety of their personal and property for students in school. If they agree to food safety items entering the campus, and students have accidents on campus, then the school will be legally responsible for certain mismanagement. Therefore, there is a certain reason why the school does not allow takeaway into the campus.

　　Pang Caiyou, Director of Beijing Shangheng (Nanning) Law Firm

　　The takeout chaos should have been controlled long ago

　　As a parent, I support the school’s regulation of takeaway food. Parents are worried not only about safety, but also about the health of their children. Many takeaway foods are not guaranteed to be healthy even if they are safe. Due to cost considerations, the quality of the ingredients selected by some merchants cannot be guaranteed, which will affect physical health. Moreover, children’s studies are not so stressful that they don’t have time to eat. Most of them want to be lazy. From a certain perspective, takeaway helps children develop bad habits. The takeaway chaos should have been controlled long ago!

　　Ms. Wang, Parent of University of Science and Technology of China Class of 2017

　　The school should not ban it

　　I have seen a lot of "complain" about college cafeterias on the Internet, and I have experienced it myself, such as the food is unpalatable, expensive, and unhygienic. In my opinion, it is inappropriate and unacceptable for schools to adopt a "one-size-fits-all" management method to ban takeout from entering campuses. If schools really start from the perspective of students, solving the campus safety problems caused by takeout should start from two aspects: improving the quality of cafeterias and standardizing the management of takeout personnel entering campuses.

　　Wang Jian, a citizen of Changsha, Hunan

　　Campus ban on takeout is understandable

　　From the perspective of campus management, it is understandable to ban takeout and packaging boxes from entering the campus. Some institutions have formulated this regulation to strengthen food safety management. At the same time, from the perspective of campus-wide environmental hygiene management, it is necessary to ban takeout. Schools, as the responsible person for the safety of students’ lives and property, are responsible for the personal safety of students during school. It is understandable to take measures to eliminate hidden dangers before finding more effective management methods.

Beijing Central Broadcasting Network reported on September 17 that if revenue performance and conversion rate are the superstructure of a catering enterprise, then the catering supply chain is the foundation for the development of a catering enterprise.

In recent years, restaurant chain has become the mainstream trend of the development of the catering industry. Correspondingly, the catering supply chain enterprises have also undergone profound changes, and are changing from a single, traditional to a comprehensive and intelligent direction.

While a number of catering supply chain enterprises have risen rapidly, major catering enterprises have also begun to strengthen their supply chain construction and seek new development breakthroughs.

(Picture provided by the enterprise, issued by the Central Broadcasting Network)

JD.com Catering partners with Maxim to deeply empower the development of the catering supply chain

It is reported that on September 14, JD.com Catering and Maxim signed a strategic cooperation agreement. The relevant person in charge of Maxim said that this signing is a milestone for both parties.

As one of the largest catering groups, Maxim’s has been in the industry for 65 years. So far, it has expanded nearly 80 catering brands and operated more than 1,800 high-quality baking and catering stores in China and South East Asia. To support such a huge catering group, it needs a strong supply chain to back it up. To this end, Maxim is actively building its own supply chain system while also seeking a better third-party cooperation platform.

Meixin and JD.com Catering signed a strategic cooperation agreement (photo provided by the enterprise, issued by China Central Broadcasting Network)

In this cooperation with JD.com Catering, Meixin can rely on the JD.com Catering platform to create integrated supply chain solutions from food supply, warehousing and logistics to procurement digital operation management, and explore a better supply chain development model for the catering industry.

JD.com Catering, as the catering business of JD.com Retail Group, has been committed to providing customized services and one-stop supply chain solutions for large and medium-sized brand catering, social group meals, hotels, canteens of enterprises and institutions, and other channels.

The cooperation with Meixin is also of great significance for JD.com Catering to enhance its brand effect, and also serves as a model for its subsequent undertaking of more national chains.

One is a well-known catering group, and the other is the leading digital catering supply chain platform. Their combination will surely bring long-term positive development to the catering industry.

With so many supply chain platforms, why did Meixin choose JD.com Catering?

According to the "2021 China Catering Supply Chain Research Report", in recent years, both listed and non-listed companies have been actively financing their supply chain layout, improving operational efficiency and optimizing industrial processes.

For medium and large chain catering brands, with the increase of volume and influence, the requirements for raw materials are getting higher and higher. At this time, whoever has a strong supply chain is likely to be invincible. However, building a supply chain by yourself is not an easy task. In addition to requiring huge capital investment, how to get through the warehousing, logistics and other links of the supply chain is also a major problem.

Therefore, due to factors such as cost reduction and quality improvement, most medium and large chain restaurants will choose to cooperate with mature supply chain enterprises in order to focus more time and energy on enterprise operation management and Product Research & Development.

(Picture provided by the enterprise, issued by the Central Broadcasting Network)

The person in charge of Meixin said that the reason why Meixin chose to cooperate with JD.com Catering is that in addition to JD.com Catering’s high reputation and recognition in the catering industry, the most important point is that JD.com Catering can not only help Meixin solve operational pain points through the digital catering supply chain, but also meet its personalized needs and provide a one-stop supply chain solution in line with its development.

1. Logistics

Zhang Haizhen, head of Maxim’s supply chain in China, said, "Maxim’s 14 food and beverage brands in the Chinese mainland, with nearly 260 stores in 15 cities across the country, and nearly 5,000 SKUs in operation, such a business layout in the existing supply chain system is a very big challenge."

JD.com Catering can use its own advantages to meet the logistics needs of all Maxim’s supply chains in one stop, helping it optimize inventory management, reduce operating costs, and efficiently allocate internal resources.

Logistics and warehousing of JD.com catering (picture provided by the enterprise, issued by China Central Broadcasting Network)

It is understood that JD.com Catering and JD.com Group Cold Chain Logistics pioneered the "Catering Business Self-operated Cold Chain B2B Warehouse Distribution System", set up 7 warehouses in 7 regions, and passed the "BRCGSS & D Global Standard System Certification", covering 24 third-tier cities across the country, which can meet the requirements of JD.com Retail Group’s self-operated cold chain 2B business.

2. Raw materials

For large catering companies like Maxim’s, its multi-brand operation covers a wide range of catering categories, involving a wide variety of ingredients and seasonings of different origins and qualities. This leads to large differences in the procurement prices of raw materials in different regions, and the dispersion of origins has caused difficulties in integration. In addition, the long chain chain of the industrial chain requires multi-level sales, and there may be problems such as distribution loss and insufficient weight in the traditional procurement process, which virtually increases the production cost and operating cost of the enterprise.

In addition, it is impossible to accurately grasp the freshness of the ingredients and the stability of the supply.

With JD.com Catering, Meixin can provide the underlying basic capability guarantee for Meixin’s core procurement link to improve efficiency through JD.com Group’s million-level commodity pool and other underlying capabilities, and can further optimize user experience and build a precise reach system.

In addition, in terms of food safety traceability, JD.com Catering will record the important data of each link in the whole life cycle of food from raw material procurement to user’s table throughout the process. Through the Internet of Things and blockchain technology, a scientific and technological mutual trust mechanism is established to ensure the immutability and privacy protection of data, which can realize the whole process of traceability and escort the whole circulation process of goods.

3. Finance

The catering industry with heavy asset operation has never been an easy business to do. Expenditures such as raw materials, labor, rent and promotion and marketing are all pain points faced by catering people. In the past two years, due to the impact of the pandemic, many catering companies have generally faced pressure such as declining revenue and reduced gross profit. Some catering companies ultimately regretted exiting the market due to a break in cash flow.

As a full stack professional catering supply chain platform, JD.com Catering can provide customers with financial services for a variety of account period solutions, including credit purchase, account period management and other modules, which can meet the business needs of catering enterprises for unified payment of multiple stores, and provide customers with the convenient experience of "advanced goods, post-payment" to assist catering enterprises in solving problems such as financial constraints in the process of rapid growth of stores.

Step 4 Retailability

The "2020 China Catering Brand Power White Paper" proposes that retailing is the "second curve" of catering brands. Many leading catering brands are involved in the retail field, and the future catering sales channels are no longer limited to offline catering stores; the combination of online and offline models, standardized and retail catering product sales is the general trend.

Under the trend, as a 65-year-old established catering group, Meixin needs to actively embrace the retail field, reshape the catering model with new retail thinking, and transform products or ingredients into retail forms to enter the market based on brand precipitation and own traffic. Through the blessing of online channels, users can achieve secondary value transformation and brand cross-channel extension, fully and directly reach a large number of consumers, and provide online sales channels with the opportunity to convert huge sales traffic. This is also the most important point of Meixin.

Next, through the collaboration with JD.com Catering, Maxim will gain more solutions in the areas of retailing and integrated marketing.

Digging deeper into the supply chain, JD.com Catering offers more possibilities for the development of catering enterprises

From the current situation of the development of chain catering, compared with foreign countries, the chain catering industry in our country is still in the preliminary stage, the concept of social division of labor of medium and large chain catering enterprises is weak, and large-scale professional catering supply chain service enterprises are very scarce.

"hanging wire for pulse diagnosis" of satellites in orbit

■ Lu Binghong Zhang Mi Liberation Army Daily reporter Wang Lingshuo

On the eve of the Spring Festival this year, Xi ‘an Satellite TT&C Center successfully completed the health status assessment of 52 Beidou navigation satellites. Through the "physical examination" of the Beidou navigation satellites in orbit, the scientific and technical personnel ensure that the key technical indicators of these satellites meet the requirements of providing various services normally and continue to maintain good working conditions in orbit.

The reason for the "physical examination" of satellites is that satellites in the past days will sometimes have "minor ailments and pains" or even "incurable diseases", which will affect business applications and lead to the failure of the whole satellite. China’s space science and technology workers are deeply involved in the on-orbit diagnosis and maintenance technology of spacecraft to realize early detection, prevention, diagnosis and treatment of satellite faults.

Satellites in orbit are so delicate.

When it comes to space flight, people often think of the rocket launch that attracts people’s attention and rises in flames. In fact, this is only the prelude to the space mission, and the work really begins when the satellite enters the scheduled orbit and is put into business application in space.

Satellites are the largest number of spacecraft launched by human beings, accounting for more than 90% of the total number of spacecraft launched, and have considerable uses in meteorological monitoring, communication and navigation, disaster prevention and mitigation and other fields. As a complex system composed of thousands of components, satellite has more and more functions and greater value with the continuous development of technology. The times of detection, diagnosis, calculation and treatment, control and disposal, and the telemetry parameters that need to be downloaded and monitored are also increasing. This puts forward higher requirements for the accuracy and stability of the ground control system. However, satellite technology is complex and dense, and it is in a complex space environment, so the probability of failure exists objectively and there are various types.

In 2018, shortly after the latest model of meteorological satellite GOES-17 in the United States was put into orbit, the cooling system failed, which made the imaging system of this satellite unable to provide satellite images in near infrared and infrared channels. Satellites can’t get infrared cloud pictures taken at night in time and effectively, and they become "blind" at night.

Coincidentally. In July, 2019, the European Galileo satellite navigation system lost all 24 satellites due to the timing error of the precise timing facilities located in Italy, and the whole system was once paralyzed. It was not until a week later that the system fully resumed service.

At the same time, satellites operate in a vacuum, weightlessness, ultra-low temperature, strong radiation and full of unknown factors for a long time, and space junk and solar activities will bring trouble and even fatal damage to satellites. Therefore, it is inevitable that there will be some technical problems during the life of the satellite.

What’s more, the cost of modern satellites is high, and with the launch cost, the cost of a satellite is often calculated in hundreds of millions of yuan. If the technical failure of the satellite is not eliminated in time or cannot be eliminated, huge economic losses will be inevitable. Therefore, once the running satellite fails, all countries will spare no effort to rescue the satellite and minimize the loss.

Troubleshooting with "Hanging Wire Pulse Diagnosis"

When there is a problem with the machine on the ground, people can locate and eliminate the fault through various methods. For satellites in orbit, it is the only way for technicians to master the attitude and working state of satellites by means of electromagnetic wave transmission.

The so-called satellite fault diagnosis and maintenance means that when the satellite fails, in order to avoid the paralysis or functional failure of the whole system caused by the failure of some components, the state detection, fault diagnosis, health assessment and other work are carried out quickly through telemetry data, the current state and future "illness" trend of the satellite are analyzed, the satellite fault level is defined, the fault location and cause are determined, and the treatment is carried out in time. This is just like the plot of "hanging the wire to feel the pulse" in Chinese classical novels and traditional operas. With this core technology, ground measurement and control personnel can detect tiny faults hidden inside the satellite as soon as possible, and after fault identification and fault isolation, take corresponding maintenance support or fault degradation treatment, so as to avoid catastrophic failures of the satellite and ensure the safe operation of the satellite.

The diagnosis and maintenance technology of spacecraft is developed with the realistic requirements of spacecraft mission expansion, control accuracy improvement and working life extension. The traditional space powers, represented by the United States and Russia, started earlier and have done a lot of research and practice in this field.

In the 1960s, with mankind gradually entering the space age, the spacecraft diagnosis and maintenance technology was also launched. Due to the limitation of technical conditions, component quality and design level at that time, people can only rely on simple instruments to monitor some key parameters of the satellite with single signal threshold state in this period to judge whether there is a fault. This method provides a certain guarantee for the on-orbit operation of early human spacecraft. At this stage, the average life of spacecraft is generally short. In manned space mission, the safety guarantee system of the system is composed of state monitoring, ground expert consultation and astronauts’ direct participation, and the autonomy, real-time and reliability of the spacecraft fault detection system are also poor.

Since 1970s, with the development of technology and the improvement of component quality, design level and process level, the diagnosis and maintenance technology based on hardware redundancy has been widely used in the field of spacecraft. The diagnosis method has also developed from simple threshold judgment to making full use of various dynamic testing technologies, monitoring technologies and information processing technologies, which has greatly extended the average life of spacecraft.

During the Apollo mission to the moon, the United States first established a flight anomaly analysis and evaluation system. The system includes flight fault monitoring and processing, flight state evaluation, flight data standardization, fault ground simulation, etc., and all emergency life-saving parameters are equipped with triple repetitive sensors and dominant voting logic circuits, which obviously enhances the autonomy and reliability of the spacecraft fault detection system.

In the 1980s, artificial intelligence research flourished, and knowledge-based diagnosis and maintenance technology, especially expert system technology, began to be widely used in the aerospace field. Among them, several intelligent fault diagnosis technologies based on expert system and testability model data-driven are the most representative. At the same time, the appearance of highly complex and reusable spacecraft such as the space shuttle makes the fault diagnosis and maintenance system not only have the distribution of modular functions, but also have the integrity of coordination. With the gradual construction and on-orbit operation of the International Space Station, its fault diagnosis and maintenance system has further greater variability, better adaptability and stronger robustness, and gradually develops in the direction of self-management, so that the failed space station can continue to complete its scheduled tasks without affecting its performance.

"Star Shepherd" guards "China Star"

The management level of long-term in-orbit satellites largely determines the realization of satellite efficiency. Since China launched the first artificial earth satellite in 1970s, the spacecraft on-orbit management and control technology has made great progress through the unremitting efforts of several generations of scientific and technological personnel.

As early as 2007, relying on Xi ‘an Satellite Monitoring and Control Center, China began to build a national-level "satellite general hospital"-spacecraft on-orbit diagnosis and maintenance center, and immediately carried out major scientific research projects in the field of spacecraft on-orbit fault diagnosis and maintenance.

With the increasing number of satellites in orbit, China urgently needs to further improve its on-orbit diagnosis and maintenance capabilities. In 2014, Xi ‘an Satellite TT&C Center established China’s first on-orbit fault diagnosis and maintenance laboratory. Through the research on early identification and location technology, on-orbit fault simulation and maintenance technology, on-orbit reliability growth and life extension technology, the independent innovation ability of on-orbit fault diagnosis and maintenance of spacecraft in China was further improved, which promoted the sustainable development of China’s aerospace engineering and became a solid foundation support for the continuous increase of the number of on-orbit satellites in China.

By collecting and sorting out thousands of fault cases at home and abroad and summarizing nearly one million pieces of diagnosis knowledge, the center independently developed an expert system for spacecraft fault diagnosis, which effectively solved the problems of late discovery, slow analysis and difficult positioning of spacecraft micro-faults.

In addition, starting from Beidou satellite, they independently developed a satellite health assessment system, established a relatively complete three-level health assessment index system of "sub-system, key single machine and key performance", put forward a meta-knowledge construction method of health assessment for single satellite in orbit, and built a detailed "physical examination file" for each satellite. The evaluation conclusions of the satellite system put forward targeted countermeasures and suggestions for the follow-up satellite on-orbit management from the aspects of key components’ operation state, abnormal prevention and response, space environment change and load efficiency guarantee, which effectively ensured the safe and stable operation of Beidou system in orbit.

As the largest long-term management center of spacecraft in China, Xi ‘an Satellite TT&C Center has been managing China’s satellites in orbit for a long time, taking on the on-orbit management tasks such as daily telemetry monitoring, orbit control, fault diagnosis and maintenance, and it is a veritable "big housekeeper" of China satellites. Although the "China Stars" are in space, they are not alone, but are always under the care of the "Star Shepherd".

In the future, Xi ‘an Satellite TT&C Center will also deeply and extensively apply artificial intelligence technology, comprehensively improve the level of diagnostic and maintenance capabilities, and lay a solid technical foundation for the on-orbit management of the "giant constellation" in the future.

　　Li Laijin is on his way to deliver takeout.

　　This summer, the number of takeaway orders in Beijing at night has increased by 60% compared with last year. According to data, Changping Huojiaying and Fengtai Minute Temple ranked first and second in the ranking of the most active business districts at night. In addition, in Yanqing District and Huairou District, the number of late-night barbecue orders increased by more than 4 times year-on-year. Behind the surge in the number of orders is every "on-time delivery" of the takeaway brothers. From 9:00 pm to 12:00 pm is the peak period of night takeaway orders. They shuttle through the streets and alleys, adding "dynamic beauty" to the night Beijing.

　　Delivery riders haunt at night "with additional subsidies and no one grabs orders"

　　"Ding Ding", at 10:59 pm, Li Laijin, who was born in 1996, received a new order.

　　From the "7-11" convenience store on Xierqi West Road to the "Contemporary City Home" community about 1.2 kilometers away, the system recommends that riders be delivered within 28 minutes.

　　"Hello sir, sorry for the long wait." After 20 minutes, Li Laijin completed the delivery, which was 8 minutes faster than the time suggested by the system. He just pressed the button to confirm "delivery completed", and the "ding ding" sounded, and the new order came again. Between 9:00 and 12:00 that night, Li Laijin sent out a total of 6 orders.

　　According to data from a takeaway platform, the number of late-night takeout riders born in the 1990s has increased by more than 60% compared with last year. Li Laijin is one of them. The site where Li Laijin works is located in Zhongguancun Software Park. During the day, orders are mostly concentrated in Internet companies, and most of the night orders come from residential areas near Huilongguan.

　　Gu Xiaofang, a 32-year-old female rider at the Wangjing shopping district, also likes to work at night. Gu Xiaofang’s site is divided into three groups. Her group has more than 30 people, and there are six or seven people who work night shifts every day.

　　"There are subsidies, there are few riders, and no one grabs orders at night." This is the main reason why Li Laijin and Gu Xiaofang like to work at night. According to Li Laijin, at the software park distribution station, the courier earns 10 yuan for delivering an order during the day, and there is a subsidy of 2 yuan for each order at night. At Wangjing Station, where Gu Xiaofang is located, in addition to the subsidy for each order, he can get an additional 20 yuan per night. In Gu Xiaofang’s view, the evening is the third time with higher income after the two dining peaks at noon and evening.

　　Mr. Jia, a 31-year-old father of two, runs more night shifts than other riders at the station. "If you run a dozen or so, you can earn 20 yuan more," Mr. Jia said. "I take the initiative to work the night shift until 12 o’clock every day."

　　According to reports, this year, Jia Shaoke has completed a total of 7,923 orders, with an average of 34 orders per day. The rider level has reached Gold 1, and the next promotion level is the most advanced king.

　　Order remarks are varied "Delivery of takeout and handwritten sweet words"

　　Many people like to write notes when ordering. Statistics from a takeaway platform show that from the beginning of 2019 to August 5, among late-night orders between 9 pm and 5 am, riders received more than 560,000 notes asking to buy cigarettes on their behalf. The request to throw garbage on their behalf ranked second, with 9,397; the third order note was somewhat unexpected, asking riders to "draw a picture". In addition, the number of messages asking riders to play games, dance, and tell jokes followed closely, with 4,595, 966, and 722, respectively.

　　Among the orders received by Li Laijin and Gu Xiaofang, buying cigarettes and snacks on behalf of others is the most common. Li Laijin said that he once visited five convenience stores to help customers buy "Yoyo Mei". He also added WeChat with customers to determine the brand type through video communication.

　　What impressed Li Laijin the most was that he once copied more than 100 words of "sweet words" for a customer and sent it with the takeaway. As for the customer’s note request, Gu Xiaofang said, "The company does not have a clear rule that must be met, but we can help with everything we can, and it is easy to do."

　　There is no shortcut to more work and more "I want to be the webmaster of the takeaway station in the future"

　　When it comes to the difficulty of delivering food, it has to be said that traveling in bad weather, about which the riders "love and hate".

　　Delivered in bad weather at night, an order can earn about 13 yuan, which is 30% higher than the usual day. And when it comes to windy and rainy weather, takeaway orders also increase.

　　Li Laijin recalled that there was a drizzle that night on August 20, and he delivered 11 orders within two and a half hours, nearly double the number of orders from the previous day.

　　After the early morning, the order interval was relatively long, and the riders began to gather together to chat. Whether the new number of kilometers ran broke the record, and whoever rose to a new high on the rider’s single king list could make them chat in full swing.

　　Due to the long-term exposure to the sun, Li Laijin’s skin was dark, in sharp contrast to his original skin tone. "The wind and the sun are a little old, but I’m still young." Li Laijin quipped.

　　Li Laijin became a delivery rider two years ago. In his opinion, this industry is more work and more money. You can earn as much money as you run as many orders, and there are no other shortcuts. "You can get as much as you do in this industry." He likes this. "As long as I have orders, I can work harder and harder, and I am not afraid to stay up late." Li Laijin said he will continue to work in this industry. "I want to be a delivery station manager in the future."

　　As soon as Li Laijin finished speaking, a "ding ding ding" prompted him: "You have a new takeaway order, please deal with it in time". Then, he quickly got on the electric car and drove into the night. Text/This reporter, Zhu Jianyong, trainee reporter, Han Qian, intern, Zhang Yujie, Zhu Yadi

　　Xinhua News Agency, Beijing, November 5th: The third step of Beidou, when the world is shocked – the secret of Beidou-3 global networking satellite

　　Xinhua News Agency reporters Hu Zhe, Bai Guolong, Yu Xiaojie

　　The third step of Beidou is to surprise the world!

　　On November 5, the Beidou-3 satellite, which has attracted worldwide attention and people’s expectations, opened the prelude to global networking. According to the goal of "completing the launch of 18 satellites around 2018, taking the lead in providing basic services to countries along the’Belt and Road Initiative ‘; achieving a global network of 35 Beidou satellites in 2020, with the ability to serve the world", China’s Beidou is making great strides to the world.

　　How will Beidou-3 achieve the "triple jump" from domestic to regional to global satellite navigation? Where is the technological lead? What surprises will it bring to people and the world?

　　Domestic, Regional, Worldwide: Beidou Navigation Achieves Historic "Triple Jump"

　　As one of the three major satellite navigation systems in the world, the Beidou satellite navigation system that travels in the earth’s orbit, from Beidou-1 to Beidou-2 to provide regional services, and then to Beidou-3 global network, continuously providing accurate and high-quality services for the majority of users.

　　"You want me to have, you want me to be excellent, serve human society and benefit the general public." Since December 27, 2012, the Beidou regional navigation system officially provided regional services, and the Beidou system has received more and more attention from countries.

　　In January 2017, the Beidou-2 satellite project won the special prize of the National Science and Technology Progress Award. Yang Hui, chief engineer of the Beidou-2 project satellite system of the Aerospace Science and Technology Group, said that the Beidou-2 satellite project took eight years of development and construction, got rid of dependence on foreign satellite navigation systems, and achieved a historic "triple jump".

　　"China’s Beidou, the world’s Beidou." It is turning from a blueprint into a reality. Xie Jun, deputy chief designer of the Beidou No. 3 project and chief chief satellite designer of the Fifth Academy of Aerospace Science and Technology Group, introduced that long before Beidou-2 officially provided regional navigation and positioning services, our country began the demonstration and development of the Beidou-3 global navigation system, and determined the development goal of building an independent, open, compatible, technologically advanced, stable and reliable global satellite navigation system.

　　Xie Jun said that compared with the Beidou-2 regional system, the Beidou-3 service area will be expanded to the world, and at the same time, key technological breakthroughs such as downlink navigation signal upgrade and transformation have been achieved, achieving a smooth transition with the Beidou-2 downlink navigation signal. On this basis, new navigation signals have been added to provide users with better services.

　　It is reported that the construction of high-performance, high-reliability Beidou global satellite navigation system is one of the 16 national science and technology major special projects in the medium and long-term development plan of our country’s science and technology field.

　　High Precision, High Reliability, High Insurance: Beidou-3 Technological Breakthrough

　　Chi Jun, commander-in-chief of the Beidou-3 satellite of the Fifth Academy of Aerospace Science and Technology Corporation, told reporters that just as water and power outages affect urban life, once the satellite navigation service fails, not only the country’s economic operation will be greatly affected, but also people’s lives will be greatly affected. This also puts forward demanding requirements for the reliability of the satellite navigation system. Overall, Beidou-3 has the characteristics of high precision, high reliability, high insurance, and multi-functionality.

　　- High accuracy. On the basis of the performance of Beidou-2, Beidou-3 was designed with the goal of the third-generation GPS navigation satellites that had not yet been launched and the design indicators of the European Galileo navigation system.

　　The positioning accuracy of the Beidou-3 global navigation system will be greatly improved, reaching the level of 2.5 meters to 5 meters. After completion, the Beidou global navigation system will provide civilian users with free positioning services with an accuracy of about 10 meters, 0.2 meters per second speed measurement service, and will provide paid users with a higher accuracy level of services. The satellite design life is more than 10 years. With the Beidou ground-based enhancement system providing initial services, it can provide meter-level, sub-meter-level, decimeter-level, and even centimeter-level services. By then, China’s Beidou accuracy will be comparable to that of the US GPS.

　　- High reliability. Beidou is a system engineering. Every time a user enjoys the service of the Beidou system, it must ensure that there are at least four satellites to provide services; Beidou is a global coverage system, and at least more than 20 satellites need to provide stable services at the same time. This feature determines that the Beidou system requires higher quality reliability than a single star, and more stringent requirements for product reliability. Beidou is also a system whose inherent properties require continuous operation. The signal cannot be interrupted, and the system must be continuous, stable, intact and reliable.

　　- High insurance. According to Wang Ping, chief designer of the Beidou-3 satellite of the Fifth Academy of Aerospace Science and Technology Corporation, the Beidou satellite global navigation system, as a large-scale system project, adopts multiple reliability "reinforcement" measures to maximize the insurance factor of the system.

　　For example, after the system is completed, the number of operating satellites is greater than the number of satellites necessary for service; at the same time, the Beidou-3 satellite also adopts a number of measures such as software redundancy, fault self-diagnosis, and fault self-repair to ensure system reliability and greatly enhance the user experience.

　　- Multi-function. In addition to features such as short messages, China’s Beidou can also send users’ location information, so that others can know the user’s situation, and better solve the problem of who, what, and where. Combining text messages with navigation is a major feature of the Beidou satellite navigation system. One end point can have both navigation and communication.

　　Far away? Close at hand! Beidou service is everywhere

　　Ofo’s small yellow cart and Beidou Navigation jointly launched the Beidou smart lock; the small blue bicycle used the Beidou foundation enhancement system to achieve meter-level positioning, even in the shade of the tree, there will be no "drift"… In order to report "where I am" more accurately, shared bicycles have been connected to the Beidou high-precision time and space positioning service one after another.

　　Shared bicycles are just one of the applications that Beidou has in the near future to serve people’s livelihood. From emergency rescue and disaster relief to precision agriculture, from fishery broadcasting to smart housing management… In recent years, various high-precision location-based service products of Beidou satellite navigation have been widely used in all aspects of the national economy and people’s livelihood under the new model of "Beidou + Internet + Other Industries".

　　The recently released White Paper on the Development of China’s Satellite Navigation and location-based service industry (2016) shows that the total output value of our country’s satellite navigation and location-based service industry reached 211.80 billion yuan in 2016, an increase of about 22.06% over 2015. Beidou’s contribution rate to the core output value of the industry reached 70%, and our country’s satellite navigation and location-based service industry has broad prospects.

　　"At present, Beidou applications in our country have entered a stage of rapid development. With the combination of satellite navigation technology with the Internet of Things, big data, cloud computing and other technologies and fields, satellite navigation and location-based services have become important strategic emerging industries in our country," said Min Yiren, deputy director of the National Bureau of Surveying, Mapping and Geographic Information.

　　In Hainan Wenchang Qinglan Port, the Beidou navigation end point is the standard for fishermen to go to sea: the operation can be monitored in real time, the fishing boat can be alerted at any time when it is in danger, and the weather forecast and early warning notification can be listened to at sea. Beidou has become the "clairvoyant", "downwind ear" and "amulet" in the mouth of fishermen…

　　Yu Xiancheng, president of the China Satellite Navigation and Positioning Association, said that Beidou technology has jumped out of the category of single navigation technology. Under the urgent needs of various industries such as urban gas, urban heating, power grid, water supply and drainage, the National Beidou Precision Service Network has provided Beidou precision services for various industry applications in more than 400 cities across the country, effectively promoting the optimization and improvement of smart city infrastructure.

The "2024 China Beverage Industry Trends and Outlook" report released by Nielsen IQ shows that with the development of social economy, the beverage industry as a whole continues to lead the fast-moving consumer goods market. Entering 2024, the consumption scene, consumer demand, and sales channels of China’s beverage market are becoming increasingly diverse, and the future beverage market will also have the potential to "cycle through". At the same time, "quality-price ratio" replacing "cost performance" is becoming a new consumption concept recognized and pursued by a considerable number of consumers. Faced with such an obvious consumption trend, how can brands seize the opportunity and seize the market?

Under the trend of quality-to-price consumption, Big Kiln Beverages continues to gain the favor of the market and consumers by relying on an efficient and high-quality process that guides product design with demand insights.

The representative "big soda" product line of Dayao Drinks has three flavors: classic guest flavor, lychee flavor, and orange flavor. Recently, 520mL of pineapple flavor and PET series of lime flavor, pineapple flavor, and frozen pear flavor have been added, which are widely welcomed with outstanding taste. For example, Dayao frozen pear, the taste not only retains the freshness and sweetness of the frozen pear itself, but also combines the carbonated bubbles to make the taste more refreshing and rich. Return to Erbin’s Frozen, and continue to harvest a good mood.

In addition, in 2024, the big kiln beverage soda product will be upgraded to the juice version, integrating the original classic taste with the juice demand, and continuously upping the ante juice soda category on the basis of retaining the core characteristics of "refreshing atmosphere" to meet the diversified needs of consumers.

Product performance is outstanding, and quality requires strength to escort. Dayao Beverage has always attached great importance to product quality, and strictly checked from raw material procurement to production process. In terms of production, Dayao Beverage has opened up a full-link digital journey from channels, commodities, marketing, orders, payment to delivery with the help of digital technology, driving cost reduction and efficiency through digitalization. In March this year, Dayao Beverage organized various factories to hold a production mobilization meeting, and conducted a full range of process, operation, quality and other training for production front-line employees to improve the quality control awareness of operators, and ensure product quality while increasing production. Each factory carried out process standard implementation investigation and error prevention landing investigation, improved 41 control measures, strictly grasped the implementation of standards, and carefully guarded product quality.

While ensuring product quality, Dayao Beverage also reduces costs and increases efficiency, improving the competitiveness of enterprises. Since 2014, Dayao Beverage has continued to build production bases in Hohhot, Shenyang, Liaoning, Siping, Jilin, Shizuishan, Ningxia, Baoji, Shaanxi, Tai’an, Anhui, and Fuyang, covering North China, Northeast China, Northwest China, Central China, East China, and South China, narrowing the distance between the production end and the consumption end. Under the condition of ensuring product quality, it reduces transportation costs and channel distribution costs, and provides consumers with higher quality and cost-effective products, such as 520mL of large glass soda, which is comparable in price to about 330mL of conventional soda on the market. Many consumers say that Dayao soda is very enjoyable to drink when serving meals, and the price is also very reasonable.

In this way, Dayao Beverage adheres to market-oriented, consumer demand-oriented, steady innovation, and is committed to bringing consumers higher-quality products, leading the national soda into a new era of quality.

In recent years, Shandong Telecom has implemented the China Telecom Group’s "cloud transformation and digital transformation" strategy according to local conditions, firmly grasping the opportunity of digitalization, networking and intelligent integration development, empowering thousands of industries with digital transformation, and effectively promoting high-quality economic and social development.

Cloud computing bases deeply empower the digital economy

As a core resource in the digital age, computing power is the main productive force supporting the development of the digital economy. It is estimated that from 2016 to 2020, every 1 percentage point increase in the scale of computing power in our country will drive the growth of the digital economy by 0.4 percentage points and the GDP by 0.2 percentage points.

Railways or highways are the cornerstones of the power era, and cloud-network integration infrastructure is the foundation of the computing power era. "Cloud computing that provides computing power" and "network that provides connection and transmission capacity" are accelerating their integration, and computing-network integration has become an important direction for the development of computing power. On the one hand, in the digital economy era, computing power is required on a large scale, which is reflected in cloud computing at the infrastructure level; on the other hand, it is necessary to connect computing power in different locations through the network, and dynamically dispatch computing power to meet the needs of different groups of people and different enterprises. Therefore, in the computing power era, it is necessary to integrate cloud and network to form a foundation for promoting economic development.

China Telecom is providing rich computing power solutions, allowing large and medium-sized enterprises to enter the "computing power era" more and more deeply.

Smart classroom builds urban and rural teaching community

During the Warring States Period, the Jixia Academy, located in Linzi, the capital of Qi State (now Linzi District, Zibo, Shandong Province), became a major innovation in the history of Chinese education development. It was the earliest government-run institution of higher learning in the world, as well as the earliest Academy of Social Sciences and government think tanks in China. As the center of academic contention at that time, it contributed to the formation of academic contention.

Today, more than 2,000 years later, Zibo has once again witnessed the technological innovation in the history of education. In a rural middle school 25 kilometers away from Huantai County, Zibo, students can listen to the famous teachers of the county middle school through an interactive online teaching system. This "real person face-to-face" online teaching method is more realistic than traditional distance teaching. Various demonstration images and model props are more three-dimensional and fresh, bringing teachers and students a refreshing immersive classroom experience.

Under the guidance of the Zibo Education Bureau, Shandong Telecom has joined hands with Huashi Cloud Technology to jointly create an AI synchronous classroom teaching system, which has benefited 447 schools in Zibo. The first phase of the project covers 1720 classrooms through the 5G ?? education special network, and the online teaching client side covers 30,000 teachers, serving the teachers and students of primary and secondary schools in the city. 5G ?? VR classroom, which can realize the learning of science experiments and other courses, students can learn knowledge in the virtual reality world and enjoy an immersive learning experience; 5G ?? Remote live broadcast, breaking geographical restrictions and realizing the sharing of educational resources; 5G ?? MR multi-person collaborative teaching, achieving the learning effect across virtual and real space…

In response to the problems of uneven, insufficient and poor opening of courses in rural schools, Zibo uses this online smart classroom teaching system to carry out pairing assistance and personalized customization, promote the regular normalization of urban and rural network dual-teacher classrooms, and carry out curriculum research in urban and rural areas. Research on learning conditions, technology and curriculum integration and application research, urban and rural lecturers and teaching assistants work closely together to achieve the effect of 1 > 1 > 2, benefiting 200,000 teachers and students. Gaoqing County, as the only county along the Yellow District of Zibo City, still has a big gap in the allocation of teachers in rural primary schools along the Yellow compared with county schools. The county makes full use of the smart classroom teaching system, the number of online students per week reaches more than 12,000, the learning effect is significantly improved, and the student praise is 97%.

Smart Classroom introduces high-quality teaching resources into rural schools, turning the classroom into a visual, scene-based, immersive, and interactive "wisdom feast", accurately solving the current problems of large teacher demand gaps and insufficient supply of educational resources, and further translating the dream of balanced education into reality.

Connect upstream and downstream to promote industrial ecological prosperity

In the huge petrochemical plant area, there are many pipelines and towers. On the large screen of the intelligent monitoring center, you can see the green logo representing the safety status constantly appearing above the pipelines and towers. Infrared thermal imaging and gas detector split-screen can sense and monitor temperature exceeding standards and gas leakage… These scenes full of technology are launched after integrating a series of 5G-related vertical applications.

In the aspects of equipment monitoring, data collection, data transmission, and equipment inspection, oilfield refining and chemical enterprises have strict requirements for the use of wireless networks, which provides opportunities for new technologies such as 5G and visual recognition.

Sinopec Shengli Oilfield Branch and Shandong Telecom have established a comprehensive strategic partnership in the fields of smart oilfields, oil and gas production and industrial Internet information services, and jointly explore the deep integration of 5G communication, IPv6, industrial Internet of Things platform, cloud, big data, artificial intelligence, blockchain, data information services, data disaster recovery and disaster preparedness, cyber security and other technologies with the industry.

Shandong Telecom Dongying Branch and the second-level units of Shengli Oilfield have successively cooperated in the field of 5G customized network, jointly deployed 5G edge private network in Shengli Oilfield Luming Qingnan Oil and Gas Development Co., Ltd., realized the commercial landing of 5G super uplink service and edge UPF, promoted and implemented the 5G customized network of the adjacent mode, and created an integrated customized fusion service through the five-in-one customized network of "network edge cloud service" to achieve "cloud network integration, on-demand customization". The implementation of "5G Edge UPF" in the Luyuan Management Area of Shengli Oilfield Lusheng Oil and Gas Development Co., Ltd. helps to build a 5G smart oilfield management area, which can meet the personalized needs of the smart oilfield management area for high-resolution video return, massive machine communication and ultra-reliable low-latency communication. At the same time, combined with the application of new generation technologies such as artificial intelligence and big data, it presses the acceleration button for the construction of the smart management area of Shengli Oilfield.

Smart port, establishing a "China sample"

Rizhao, which has the reputation of "two ports connect the four seas, and the first line connects Asia and Europe", is the eastern bridgehead of the New Eurasian Continental Bridge Economic Corridor, the main node city of the New Eurasian Continental Bridge Economic Corridor, and the strategic fulcrum of the "Belt and Road Initiative" maritime cooperation. Rizhao Port’s throughput ranks sixth in the country’s coastal ports and is the ninth largest port in the world.

However, the container operation volume of Rizhao Port has grown rapidly, the risk factor of human operation in bad weather is high, and the port trucks work multiple shifts and labor costs are high. These pain points urgently need to accelerate the implementation of intelligent applications such as driverless driving. In order to help Rizhao Port break through the development bottleneck and build a fully automated container terminal, Shandong Telecom Rizhao Branch and Rizhao Port have formed a close cooperation relationship and continue to empower the 5G customized network driverless project.

The unmanned truck self-driving project gives full play to China Telecom’s strong cloud-network integration strength, and based on 5G technology, it has built the world’s first shoreside open fully automated container terminal, providing global ports with a "Chinese sample" of the transformation of traditional terminals into fully automated container terminals. It is of great demonstration significance for leading the construction of fully automated container terminals with "low cost, short cycle and fast effect".

The project has planned three business scenarios that fit the port business, including the remote control of port machinery, the remote driving of the truck, the precise positioning of the shore bridge and the container, and realized the precise driving route of the heavy truck (the wheel and the driving line maintain a distance of 20cm) and the precise parking and the precise positioning and transportation of the container by the crane, which greatly saved the cost of the terminal transformation. At the same time, due to the closed automated terminal design with controllable whole process, the stacking density is higher, and the land utilization rate of the port is higher. For the seventh time, Rizhao Port broke the record of the world’s first automated terminal loading and unloading efficiency maintained by itself.

The 5G "ultra-long-distance" remote intelligent driving technology in Rizhao Port has good handling and safety. It can return 7-way 1080p high-resolution video in real time, covering the driving perspective of the vehicle and the blind spot of the vehicle. It includes an automatic protection mechanism under abnormal network conditions, ensuring the safety of operations and making remote intelligent driving possible. This application accelerates the automation and intelligent process of Rizhao Port, improves the efficiency of terminal operations, and contributes telecommunications power to accelerate the construction of a world-class marine port.

As a national key basic network operator and the main force in the construction of digital China, Shandong Telecom will make full use of 5G, Internet of Things, artificial intelligence and other new generation Information Communication Technologies in the "computing power era", focusing on industry, education, medical care, energy, finance, government affairs, agriculture, small and medium-sized enterprises and other fields to strengthen scientific and technological empowerment support, and paint a brilliant picture of the development of digital economy in Qilu.
