Shanghai Port Yangshan Port Pilot Pilot Autopilot Heavy Truck Efficient Service Port Collection and Distribution

In November 2019, Yangshan Port Area of Shanghai Port launched the "5G+L4" smart heavy truck demonstration operation project (referred to as the demonstration project); In December 2021, Yangshan Port Area of Shanghai Port automatically drove heavy trucks to complete the transportation task of 40,000 TEUs in that year; In September, 2022, the pilot application of automatic driving for container horizontal transportation and port collection and distribution in Shanghai Port Area was approved, and the first batch of intelligent transportation pilot application projects (referred to as pilot projects) were approved by the Ministry of Transport …

Recently, the three-year development results of the demonstration project released by Shanghai show that up to now, the self-driving heavy trucks in Yangshan Port Area of Shanghai Port have completed more than 4 million kilometers of test operation and transported more than 140,000 TEUs. Among them, the vehicle travels autonomously (without the intervention of the security officer) for more than 2000 kilometers. With the maturity of automatic driving technology, the promotion and application of automatic driving heavy trucks in Yangshan Port Area of Shanghai Port are accelerating, and the port collection and transportation are continuously and efficiently served.

Improve operational efficiency and invest more than 60 vehicles by the end of next year.

According to the requirements of the pilot project, how will the self-driving heavy truck serve the collection and distribution of Yangshan Port in Shanghai Port? The relevant person in charge of Shanghai International Port (Group) Co., Ltd., the lead unit of the pilot project, told the reporter that in 2021, the container throughput of Shanghai Port exceeded 47 million TEUs, of which the container throughput of Yangshan Phase IV automated terminal exceeded 5.7 million TEUs, up 35.7% year-on-year. According to the planning of the pilot project, by the end of 2023, Shanghai will invest no less than 60 self-driving heavy trucks in Yangshan Port-Donghai Bridge-Lingang Park, and the accumulated container collection and distribution volume will be no less than 300,000 TEUs.

"Promoting the application of self-driving heavy trucks will greatly improve the operational efficiency of Yangshan Port Area of Shanghai Port." Wang Rui, CEO of Shanghai Youdao Zhitu Technology Co., Ltd. (referred to as Youdao Zhitu), an important participant in the pilot project, said that in Yangshan Port Area of Shanghai Port, it takes 90 seconds for a skilled truck driver to drive a heavy truck into the operation area, while it only takes 70 seconds to drive a heavy truck automatically. Based on 5G and V2X technologies, the automatic driving heavy truck in this port area has achieved centimeter-level positioning and accurate parking, and the success rate of warehousing has reached 100%. From parking and warehousing to loading and unloading trucks, to entering and leaving Donghai Bridge, automatic driving of heavy trucks has improved the working efficiency of the port area in many aspects.

Donghai Bridge is the only land passage in Yangshan Port Area, and its traffic efficiency is very important for the port development. "On the Donghai Bridge, Youdao Zhitu has realized the automatic driving of heavy trucks, with a speed of up to 80 kilometers per hour and a minimum distance of 15 meters, which effectively improves the transportation efficiency of the fleet, thus helping to alleviate traffic congestion." Wang Rui said.

Speed up the reduction of staff and test the vehicle’s "vision" to perceive objects 1 km away.

In July this year, the Traffic Police Corps of Shanghai Public Security Bureau issued a notice to implement the management of autonomous driving test lanes in Donghai Bridge. The relevant person in charge of the Shanghai Municipal Transportation Commission believes that it is difficult to achieve economic benefits if the number of safety personnel cannot be reduced. The test lane provides the necessary guarantee for the attrition test, which is of great significance for the popularization and application of automatic driving heavy trucks.

According to Wang Rui, according to the requirements of the pilot project, Yangshan Port Area of Shanghai Port will speed up the attrition test of the self-driving heavy truck queue and reduce the number of security officers equipped in some vehicles. By the end of this year, Youdao Zhitu will realize the formation of five self-driving heavy trucks on Donghai Bridge, among which only one safety officer is required for the first and second vehicles.

The reporter learned from the Shanghai Municipal Transportation Commission that the pilot project of reducing the number of employees of self-driving heavy trucks in Donghai Bridge will form a number of standards for communication, operation and management of self-driving heavy trucks, and accumulate valuable experience for formulating and implementing relevant laws and regulations.

There is no security officer in the car to take over at any time. How can the automatic driving system ensure the "zero mistakes" in the safe driving of the vehicle?

"As a manufacturer of self-driving heavy trucks in Yangshan Port Area of Shanghai Port, SAIC Hongyan Heavy Truck is based on advanced equipment such as visual perception system, laser radar system, millimeter-wave radar system, satellite and inertial navigation independently developed by Youdao Zhitu, with multi-dimensional and 360-degree perception. It can accurately perceive traffic participants within the range of 250 meters from front to back and 80 meters from left to right, and accurately identify and avoid pedestrians, vehicles and other obstacles." The relevant person in charge of SAIC Hongyan said.

The reporter learned that SAIC Hongyan and Youdao Zhitu belong to SAIC Group. Combined with the actual operation in Yangshan Port Area of Shanghai Port, the two parties have jointly sorted out 11 categories and 1216 failure modes of autopilot systems, and formed 758 fail-safe protection schemes, which have completed simulation and real vehicle testing. At present, the self-driving heavy truck in Yangshan Port Area of Shanghai Port can "see clearly" objects 1 km away, and accurately identify 200-meter cones and 10-centimeter tiny objects.

Collecting and using the full stack of data to solve the bottleneck problem

Both demonstration projects and pilot projects are doing technical accumulation for the commercial operation of self-driving heavy trucks, thus promoting the solution of various bottleneck problems. There are complex weather conditions such as high temperature, typhoon, rain and fog in Yangshan Port Area of Shanghai Port, and the Donghai Bridge has a large traffic flow and many models, which bring certain challenges to the popularization and application of self-driving heavy trucks.

According to the division of labor of the pilot project, Youdao Zhitu will focus on solving the complex scenes composed of weather, roads, traffic participants and other factors, resulting in problems such as difficult perception, difficult decision-making and difficult control of automatic driving heavy trucks.

Collecting data is the first step. According to reports, at present, Youdao Zhitu has 40 self-driving heavy trucks tested in Donghai Bridge every day, of which 20 are tested all day. Through large-scale testing, Youdao Zhitu has accumulated massive operational data and further used the data to promote the upgrade of autonomous driving technology. Taking the Honghu platform as an example, Youdao Zhitu has used its operational data to upgrade its system for more than 90 times.

On the basis of accumulating and making full use of data, Youdao Zhitu and SAIC Hongyan will jointly promote the full-stack self-research of self-driving heavy trucks, and integrate the "soul" (technology) and "body" (vehicle) of self-driving.

"Full-stack self-research is an inevitable way determined by the data-driven model. Only by integrating data into vehicle design can we solve the long tail problem of automatic driving." Wang Rui believes that the full-stack self-research by heavy truck manufacturers and autonomous driving solution providers can better combine the perception, decision-making, control and implementation of autonomous driving technology.

At present, the pilot project is connecting information in series to form an information flow by opening up every related system in Yangshan Port Area of Shanghai Port, thus promoting the upgrading of autonomous driving technology and accelerating the commercialization of autonomous driving heavy trucks.

Blind roads in cities are very busy. Blind people: There are too many "traps" on blind roads, which are unsafe.

The blind road in the city is very busy. The blind man tells us that there are too many "traps" on the blind road, which is unsafe.

Dahe News (Reporter Li Shuai) Core Tip | "My eyes are intact, but why can’t I see them." In an interview the other day, a Zhengzhou citizen asked our reporter a question: Why did they walk to and from work for three years, but they didn’t see a blind friend? Where did they all go?

According to the data released by the World Health Organization in 2010, there are 8.248 million blind people and 67.274 million people with low vision in China. There are many blind people, but why do we seldom see them in our daily life?

doubt

Why can’t I see a blind man after walking the blind road for three years?

At 7 o’clock on the morning of December 19, on Dongming Road in Zhengzhou City, 25-year-old Xiao Zhou just walked to the sidewalk on the side of the road, so he couldn’t help but take out his mobile phone from his pocket and slowly turned to the blind road. Along the way, except crossing the intersection, he hardly looked up; Even when waiting for the traffic lights, he looked down at his mobile phone from time to time. On the way, he almost ran into an electric car parked on the blind road twice, which made the reporters who followed him feel a cold sweat. Afterwards, when he found the reporter following, he also argued that he was experiencing the feeling of blind people traveling.

Xiao Zhou is a chef. Every day when he goes to work, he walks from the rented house to the hotel where he works, with a distance of more than 2,000 meters. On this section of the road, most of the time he will watch his mobile phone while walking in the blind road, and observe the road conditions on the blind road with the corner of his eyes. In his words, the blind road can guide his walking route, and his feet have been "exercised" very sharply. The straight line under his feet is straight, and when he meets a raised dot, he turns.

In addition, he also observes whether there are blind people on the blind road from time to time, but he has never seen a blind person on his way to and from work for three years.

"I am also puzzled. On the sidewalk, I may not notice the blind people around me, but why have I been walking on the blind road and never seen the blind people?" Xiao Zhou said that he is now used to walking on the blind road and observing whether there are blind people on the blind road. "I also want to help the blind friends I met, but why can’t I see them with my intact eyes. Did I go out at the wrong time? Or blind friends don’t go out? "

inner voice

It’s not that they don’t want to go out, but they are afraid to go out.

At 11 o’clock on the morning of December 20, the reporter met several blind friends in the blind massage service center of Sunshine House, Zhengzhou University Road. At this time, some of them are doing massage for the citizens, while others are cooking in the kitchen. Chen Qiang, 52, is one of the blind masseurs in this massage shop. When he was two years old, his cornea was burned by a high fever, and the medical conditions at that time limited him, so that he was blind since he was two years old. Now, the blind stick in his hand is his eyes when he goes out.

Why do you seldom see blind people in your daily life? When the reporter asked Chen Qiang about this question, Chen Qiang said with a sigh that it was not that they didn’t want to go out, but that they were afraid to go out. Although there are blind roads on the road for blind people to travel, there are too many "traps" on the blind road, which is unsafe. Before, when he was in Kaifeng, his hometown, he almost fell into a manhole without a manhole cover on the blind road. "At that time, one of my feet was already empty and I was about to fall in. Fortunately, a good-hearted person grabbed me in time."

Hearing this, another blind masseur next to me, Jin Guoquan, couldn’t help but say, "Last year, I broke my bone on the blind road in huanghe road, Zhengzhou, and I lost two thousand yuan after a year of litigation. Now I basically don’t dare to go out."

Not only Jin Guoquan was injured in the blind road, but even Zhao Wanfu, a blind masseur who was cooking, suffered losses in the blind road. According to Zhao Wanfu, half a month ago, when he went out to buy steamed buns, he was hung around his neck by a cable pole on the blind road. Although it was not very serious, his neck was burning for several days. "We also want to go out and go to the small park to bask in the sun, but there are too many unsafe factors on the road, so we can stay indoors."

In addition, Chen Qiang also told reporters that once, when he went out to buy things, he knocked and walked with a blind cane, and he accidentally knocked on a car on the blind road. The owner began to swear after getting off the bus. If other citizens had not stood up for him, he really didn’t know what to do at that time. Although it has been a long time since this incident, and he himself said that he can’t remember how ugly the words were at that time, it made him sad for a long time, and he was very grateful to the citizen who helped him speak.

In this regard, Tian Chao, vice chairman of China Blind Association and chairman of Henan Blind Association, said that according to their latest blind census, there are currently 76,400 blind people in Zhengzhou. Inconvenient travel and transportation are the reasons why many blind friends are reluctant to go out.

site

Line poles, isolation piles … There are many "traps" in street blind roads.

On the streets of Zhengzhou, there are blind roads on the sidewalks of almost every road, but these blind roads are either blocked by motor vehicles and non-motor vehicles, or occupied by telephone poles and isolation piles, or seriously worn, or even "broken" roads. During the interview, many blind friends interviewed said that there are too many "traps" on the blind road, so it is better not to leave.

During the visit, the reporter also saw many chaos on the blind road on the streets of Zhengzhou. For example, in the sections of Kangfuqian Street and Zhengqi Street in Zhengzhou City, telephone poles are directly erected on the blind road; On the South Yellow River Road, there are isolation piles directly on the blind road; On many roads such as Dongming Road and Hongzhuan Road, blind roads are cut off and blocked by motor vehicles and non-motor vehicles; Even the street merchants in some sections regard the blind road as an isolation line, and put dirty trash cans on the side of the blind road …

Imagine what would happen if we lost the light and walked on such a blind road? If you stand on a busy street, or stand at a bus stop and wait for a bus, close your eyes and experience the feeling of blindness, you will find that it seems that the whole world has become extremely unsafe, surrounded by noisy voices and unknown uneasiness. Even before you close your eyes, you already know that the road ahead is very flat, or you know how to get on the bus, but you will still be timid and afraid to move forward.

suggestion

I hope the blind road can really play its role and add more voice reminders.

During the interview, blind friends all expressed the hope that the blind road can really play a role, and that there will be fewer "traps" on the blind road and the design will be more reasonable. Especially at some small intersections where blind roads are broken, some voice reminders can be added so that blind people can pass safely. Among them, Master Zhang, a blind friend interviewed, asked whether it is possible to set up blind roads on the zebra crossing at the intersection so that the blind roads on both sides of the intersection can be connected together, so that the blind can continue to walk on the blind road after passing the intersection.

In addition, Chen Qiang, a blind friend interviewed, also asked whether it is possible to set up a voice reminder at the intersection of traffic lights, so that the blind can cross the road safely, instead of running the red light with the people next to them when they hear them walking forward.

In addition, Tian Chao, vice chairman of China Blind Association and chairman of Henan Blind Association, also said that blind people mainly rely on public transportation. If we can set up a voice reminder of blind people crossing the road at the intersection of urban traffic lights and install a bus guide system as soon as possible, it will not only ensure the safety of blind people’s travel, but also make it more convenient for blind people to travel.

fill

According to the regulations on the practical assessment standard for the disabled in China (for Trial Implementation), the disability of visually impaired people is divided into four grades, namely, first-degree blindness (first-degree visual disability), second-degree blindness (second-degree visual disability), first-degree low vision (third-degree visual disability) and second-degree low vision (fourth-degree visual disability). For the convenience of description, blindness and low vision are expressed as "blind" in the report.

Digital audio solution will open the era of QQ paid music.

  An IPhone +QQ music player+digital audio standing wave processor+world cable box, with a simple and unexpected combination scheme, won the attention of countless media, industry insiders and experienced fans at the 2017 Shanghai International HI-FI Audio Exhibition (SIAV), and stood out from the noisy exhibition with its shocking playing conclusion.

  Genesis (Singapore) Technology Co., Ltd. and Xuran Group, following the discovery trip in Hai Yin, Guangzhou on April 16th, once again took advantage of the Shanghai International HIFI Exhibition to release the new digital recording and broadcasting method of "Discovery, New Sound Machine"-"Digital Audio Solution". Under the witness of more than 60 media, nearly 3,000 people in the industry and experienced friends, Xuran Group demonstrated to the media and the public how digital audio solutions can solve the pain points in the audio industry from the root and promote a great leap in sound quality.

  Only IPhone +QQ music player +KEF speaker, such a simple digital audio playback scheme, after loading the digital audio solution, that is, the world cable box and digital audio standing wave processor, the sound quality can reach HI-END level. At the event site, we showed: IPhone +QQ music player +KEF speaker, and the comparison between the loading and unloading of the world cable box and the digital audio standing wave processor. The participants at the scene were deeply shocked by the conclusion of playing QQ music after loading the digital audio solution. Some people in the industry even felt that this would rewrite the history of the audio industry and was definitely a subversive innovation. The veteran enthusiasts at the scene even bluntly said that they "don’t have to buy any vinyl or CDs anymore", and even felt that their playing conclusion far exceeded the effect of CD playing, and they were willing to pay for such a conclusion. There is no doubt that the digital audio solution can greatly improve the sound quality of QQ music playback because of the empirical comparison on the spot and the reaction of the participants.

  Does this mean that the emergence of digital audio solutions will activate the new commercial profit model of streaming media operation?

  On-the-spot analysts pointed out that QQ music keeps up with the trend of the mobile digital era. It has invested heavily in software development and copyright purchase, but it has been in a downturn in the paid music market, mainly due to the bottleneck of the hardware of digital audio playback carrier in audio technology. The release of digital audio solution has solved this problem. The actual playing conclusion on the spot has confirmed that after the technical solution is loaded on Apple mobile phone, the playing conclusion of QQ music makes senior fans and insiders willing to pay for it.

  Xuran Group is committed to the technical application and promotion of "Digital Audio Solution" in all fields of audio. This conference has invested more than 30 million application products to provide free experience, hoping to jointly explore and extend the commercial practice mode of this technology in the audio field through the experiences and ideas of relevant people in various fields. At the same time, a dedicated team tracks the experience feedback and provides an open platform and technical guidance scheme. In view of the mobile digital products such as mobile phones with the greatest consumption demand at present, the corresponding experience scheme of digital products is opened.

  In addition, on May 20th, Xuran Group will hold an extended application release of "Digital Audio Solution" with the theme of "Opening the Gate of Digital Audio and Establishing a New Digital Audio Standard" in Rongchao Yinglong Building, Longgang District, Shenzhen, and we will continue to pay attention to it.

After being swallowed by natural enemies, this animal can retrograde in its stomach! It’s too bad

What will happen if an animal is swallowed raw?
The seal said that this question is not funny.
In late September, in the waters near Ana cortese, Washington, a whale-watching naturalist took an unusual photo: a humpback whale was swallowing fish, and a bewildered seal was mixed in its mouth.

picture

Fortunately, seals are not a big problem, because whales can’t swallow a seal. Large whales like humpback whales, despite their huge mouths, can "eat".(lunge feeding)Intake a lot of small fish and water at one time,But their throats are only the size of grapefruit, which is far from enough to swallow prey much bigger than small fish.
The reason for being swallowed by mistake is very simple. When whales open their mouths to prey on small fish or krill, seals often feed in the same water area. If the seals get too close at this time, they may be caught in the whale’s mouth by mistake. As a result, because the whales can’t swallow, they can only spit out the seals from their mouths by repeatedly opening and closing their mouths.
The fate of seals is good. Those who are really swallowed want to live, so they have to find another way out, such as being bitten by Odontobutis.(Odontobutis potamophila)Swallowed Japanese eel(Anguilla japonica).

The "Meeting" between Odontobutis sinensis and Anguilla japonica

Japanese eels have a complex life cycle, their eggs hatch in the ocean, and their larvae are called willow eels.(leptocephali)The shape is slender and almost transparent. These larvae drift westward through the northern equatorial current, and then reach the coastal areas of East Asia by the Kuroshio current. This process lasts about 110 to 160 days, and then the larvae will become glass eels.(glass eels), gradually into the estuary and fresh water.

When the glass eel enters the river, it will stay in fresh water for 5 to 10 years. When it enters the yellow eel stage, it gradually grows and adapts to different habitats, mainly feeding on shrimp, insects and small fish. With the change of river environment, eels will migrate to different areas, such as estuaries, lakes or the upper reaches of rivers; When eels mature, they will begin to migrate to the deep Pacific Ocean in autumn to complete the breeding task.

Eels enter the ocean in the larval stage (glass eel and yellow eel stage). During this long journey, they will face survival challenges brought by various predators. One of them is Odontobutis sinensis, an East Asian freshwater fish.The prey is swallowed into the stomach together with the surrounding water mainly by fast sucking, which is especially effective for smaller organisms (such as Japanese eel larvae).
picture
Odontobutis sinensis Image source: Wikipedia
This seems to be an end moment. For most prey, entering the predator’s stomach means inevitable death. However, this time, the story did not end as expected.

The survival rate of small eels is as high as 69%

In order to observe how small eels escape from the stomach of predators, and how eels can survive tenaciously and try to escape after being swallowed by Odontobutis sinensis, Japanese eel larvae raised in the laboratory were used in the experiment. The average length of these eels was 68.1 6.0 mm (n = 104), and that of Odontobutis sinensis, a predator, was 145.4 15.6 mm (n =
The research team willBarium sulfate injectionThe Japanese eel larvae raised in the laboratory can be clearly captured by X-rays, and then the eel is put into the experimental water tank together with the "predator" Shatangyu, and the story begins.
Under X-ray, scientists found that the swallowed eels did not wait for death. They began to act in reverse, trying to swim back from the predator’s esophagus and looking for an exit. And at this time,Eels show their unique ability to escape: they can pass through the esophagus, put their tails into the gills of predators and gradually withdraw from the gills.
picture
The swallowed eel has a tail in the white circle and a head in the black circle. Image source: references[1]
In the experiment, 32 eels were swallowed by predators, among which 13 eels successfully put their tails out of the gills, and 9 eels completed the whole escape process. This process is full of thrills and struggles, like an ultimate life-and-death competition.For those eels that successfully stick their tails out of their gills, their survival rate is as high as 69%.
picture
The gills of Odontobutis sinensis were drilled from the tail of eel. Image source: references[1]
Scientists marvel at the complexity of this anti-predation strategy. They found that some eels move in a circle along the stomach wall after completely entering the stomach of predators, as if they were looking for potential escape paths everywhere.The secret of escape may lie in the body structure and swallowing order of eels.Snakeheads usually swallow their prey head forward, and eels’ tails are often left near the esophagus, which gives them a chance to escape first.

X-ray images and schematic diagrams. Figure B: The eel tail has been inserted into the predator’s esophagus, and the X-ray image clearly shows the position of the eel in the predator’s digestive tract. C: The eel tail begins to pass through the gill slits of predators, which is very important. Figure D: The eel pulls its head out of the predator’s gill, which indicates that the escape process is about to be completed. E: Eels swim around the stomach, showing an "exploratory" behavior, looking for possible escape paths. Image source: references[1]

Not only that,The experiment also revealed that eels need to respond as soon as possible in acidic and anoxic stomach environment.Once an eel enters a predator’s stomach, it can only live for about 211.9 seconds on average. Time is running out, and the boundary between life and death can often be decided in a few minutes.


picture

Eels still have to struggle to find a way out, and for "fart bugs", being eaten by toads only needs to fart.

Yefart beetle "spits fire" in the stomach.

Similar to the above experiment (without X-ray), the object of this experiment is the beetle.(Pheropsophus kimaniae)。Once the beetle is swallowed by the toad, it won’t wait for its fate quietly, but it will launch a wonderful self-rescue operation:Yefart beetleIt will release a high-temperature chemical spray, which can not only protect itself, but also make toad feel severe discomfort.

picture

Yeah, it’s a fart. Image source: Wikipedia

With a faint explosion, toad realized that he had made a mistake. In the next few minutes, toad tried to endure the stimulation of his stomach and had to make a shocking choice-vomiting.

The success rate of the "fart bug" escape from life and death is not completely random. The study found that,The bigger the beetle is, the more chemicals it releases, and the higher the chance of escape.For toads, the smaller they are, the lower their chemical tolerance, so they are more likely to spit out beetles.

It can be said that this is a contest between "big" and "small": the little toad can’t bear the chemical counterattack of the beetle, while the big beetle has a greater chance to escape calmly. Finally, if you are eaten, don’t panic, there will always be a way out, provided that you are completely swallowed raw …

Original Cai Xukun attended the event, and the appearance of the life picture is very heavy. Recently, the rumors turned out to be true.

Cai Xukun hadn’t appeared in front of everyone for a long time. It seemed that he had been busy preparing a new album recently, so he hadn’t been seen at many events. However, recently, Cai Xukun’s high-end luxury brand held an event, so he was invited to participate.

Cai Xukun’s appearance of life pictures has attracted heated discussion

It can be seen that at the event held by the brand, Cai Xukun was wearing a black suit, and his hair was dyed black and cut a lot shorter. There was no makeup on his face, and he looked in good condition. As a spokesperson, he should be the focus of the audience, but many netizens found that Cai Xukun’s temperament was different from before.

You can see this picture, it should be the reason for the short hair. Cai Xukun’s head looks a little big, which shows that this hairstyle is not suitable for him. Being black all over is already a very thin way to wear, but I don’t know why I feel that Cai Xukun’s figure is a little fat.

The face was originally a small pointed face, but from this angle, Cai Xukun’s face became much wider. I don’t know if it was widened by the camera. Although the chin is still very pointed, overall, it is less delicate than before.

And you can see that Cai Xukun’s side face is a little strange at this angle. Although his chin was also very pointed in the past, it would not be at this kind of deformation angle. Although his jaw line is very beautiful, it is a 90-degree right angle.

But there were also many people who suspected that Cai Xukun had moved his face during the time he disappeared. And from the side, although Cai Xukun’s nose was as tall as before, his nose was very small in the past, and the nose in this picture would look bulky.

It seems true that Cai Xukun’s appearance has declined, but compared with his appearance, his body maintenance does not seem to be too high. Is it because he is busy with albums every day and rarely keeps exercising? Cai Xukun is really fatter than before, but

He could see that the figure on his side was also in a state of a tiger’s back and a bear’s waist. It was also much different from the previous bamboo pole figure. Originally, he thought that Cai Xukun was really not fat, but it turned out that the male star was also an ordinary person.

It seems that the rumors surrounding Cai Xukun recently are true, because some netizens said that Cai Xukun has gained a lot of weight recently, and they also sent photos of him gaining weight. Originally, fans said it was a matter of angle.

But I didn’t expect that the latest event pictures also show signs of gaining weight. But there should be nothing to worry about, because it is impossible for celebrities to be in good condition 24 hours a day. But Cai Xukunming knew that he wanted to attend the event, but he couldn’t maintain his best state. This is everyone’s fault.

Cai Xukun generally feels like an "aunt"

Cai Xukun was also photographed by the media that day. Cai Xukun is over 180, but from this picture, you can see that Cai Xukun’s height seems to be bent a lot

He was only a little taller than the guest next to him, and Cai Xukun’s comic figure had also become much stronger. Many people felt that Cai Xukun’s temperament was a bit of an aunt.

There is also this one that makes people feel more like "aunt". Although Cai Xukun doesn’t look fat in this photo, he always has a very strange temperament on his body, and his upper body has a feeling of lateral development.

And his face looked swollen a lot under the light, and if he bowed his head, he might really have a double chin.

Previously, although Cai Xukun walked in a coquettish style, he gave people a very unique man, but I don’t know why Cai Xukun wore such a high-end and decent dress that day, but it doesn’t give people a feeling of elegance. It may really have a lot to do with the appearance of the figure. I hope Cai Xukun can return to his original figure as soon as possible. After all, the new album will come out soon, so it is still necessary to operate in the best state!

Do you think Cai Xukun is a little fatter than before? Welcome to the comment area to leave a message, and don’t forget to give the editor a like and attention, thank you all!

Peng Yuyan’s "Tropical Past" was raised to 6.12, and the skinny characters became a mystery


1905 movie network news Directed and produced by a rookie director, Peng plays Wang Xueming, whose otherwise uneventful life is transformed by a steamy summer night when the entire city loses power. Wang Xueming’s erratic choices embroil himself in a complex case that alters the fates of everyone in the story. In the exposed trailer, Peng Yuyan was ruthless without a word. The thinner image, dim eyes, and collapsed eye sockets all made the audience question "Is this Peng Yuyan?", and the raised vertebrae were completely eye-catching, which also made the audience suspicious. For this reason, Peng Yuyan said, "This scene took off a layer of skin."

 

Acting in a dehydrated state, Peng Yuyan can’t sleep at night due to self-depression  

    

Peng Yuyan plays Wang Xueming in the film, who is depressed, gloomy, and inarticulate. He always keeps his hat down and hides in the crowd, like a hidden person who has no sense of existence. Director Wen Shipei compares him to a black fish, while Peng Yuyan himself is an extremely positive optimist. Whether in life or on the screen, he is familiar with the image of positive energy, and his reason for taking the role is always related to this – "I hope it can infect or inspire people who watch movies." This time, to play a role that is very different from his own personality, Peng Yuyan needs to maintain a depressed state during the two-month shooting period. He has cut off many ways to make himself happy and immersed himself in the character’s state through physical training, dietary restrictions, and emotional control.

"Wang Xueming is not a happy person. I want to be ready when I shoot every day, so I often jog in advance, consume myself to a certain extent, and act in a dehydrated state, which is more like." Peng Yuyan revealed that during the two months of filming, he often suffered from insomnia, which coincided with the character. "Wang Xueming often suffered from insomnia, so his state was not very good, and I myself could not sleep during that time. I think this is a signal of my self-control in physical, diet and psychological, which in turn helps me to get closer to the character."

 

Revealing the original intention of the play: I hope to find the courage to face myself squarely

 

Peng Yuyan said that his original intention for taking on the role of "Once Upon a Time in the Tropics" was that he wanted to seek a kind of courage to face setbacks, and this is exactly what Wang Xueming’s role can give him. "The first time I saw the script, the most intuitive feeling was that it was very powerful. I hope this role can give everyone and myself a kind of strength. When encountering difficulties or mistakes that I dare not face, I can have the courage to look directly and bear it, and then I can grow. This is my original intention for taking this role."  

"The attraction of Wang Xueming’s character to me is that he is looking for redemption through this event. Everyone will live in the past, and some people dare not face it. Xueming wants to forget the past, but he has to face it." Peng Yuyan said that making the movie "Once Upon a Time in the Tropics" has made him grow a lot. "When you look directly at your fears and the past, you can face the sun. This is a story of character growth."

At the end of the video is lending, and Aauto Quicker won a payment license to lay out the financial industry.

  Reporter Levin Fu reports from Beijing.

  Recently, the equity of a small loan company has changed.

  On March 21st, Guangzhou Local Financial Management Bureau agreed that Guangzhou Huaduo Network Technology Co., Ltd. would transfer 100% equity of Guangzhou Huanju Microfinance Co., Ltd. (hereinafter referred to as "Huanju Microfinance") to Beijing Yunsuo Technology Co., Ltd..

  This also means that the online small loan license was pocketed by Aauto Quicker.

  In addition, on March 27th, Guangzhou Local Financial Management Bureau agreed to approve the change of senior managers of Huanju Small Loan.

  On April 2 nd, Su Xiaorui, a senior researcher at Suxi Zhiyan, toldThe reporter said that after obtaining the small loan license, Aauto Quicker is expected to enter the consumer finance business, and refer to the existing paths of Internet traffic giants, package it as loan products such as Aauto Quicker installment or credit payment products such as Aauto Quicker monthly payment, so as to seek greater scale growth in the financial field.

  Quietly buy

  According to the announcement, Guangzhou Huaduo Network Technology Co., Ltd. will transfer 100% equity of Huanju Small Loan to Beijing Yunzha Technology Co., Ltd. After the transfer, Beijing Yunsuo Technology Co., Ltd. holds 100% equity of Huanju Small Loan and becomes the main sponsor of Huanju Small Loan.

  In this transaction, Guangzhou Huaduo Network Technology Co., Ltd. is the parent company of Huanju Times, which was listed on NASDAQ in November 2012. Its business covers live broadcast, short video, games and other fields, and its core product is the interactive live broadcast brand "YY Live".

  Enterprise investigation shows that Huanju Small Loan was established in January 2016, and its registered capital reached 1 billion yuan in 2018, which was reduced to 500 million yuan in February last year. Huanju Small Loan used to be the main operator of YY Credit, which is a consumer finance platform, providing YY credit, loan, anchor loan, consumption installment and other products for users in various scenarios of YY.

  Through equity penetration, the ultimate controller of Beijing Yunzha Technology Co., Ltd. is Aauto Quicker Technology.

  It can be said that Aauto Quicker indirectly obtained a network small loan license.

  The reporter found that the platform of Aauto Quicker APP "My Wallet", a loan product, has made diversion for the piggy bank and other institutions. For example, clicking "Apply Now" shows that the piggy bank can borrow up to 200,000 yuan, with an annualized interest rate of 7.2% and interest-free for a limited period of up to 30 days.

  Aauto Quicker’s borrowing business does not directly involve risk control and loan issuance, but adopts diversion mode. Aauto Quicker displays the loan products of third-party institutions on its platform, and guides users in need to apply for loans from institutions. Users submit mobile phone numbers, supplementary information, etc., and the cooperative institutions are responsible for credit evaluation, approval and lending.

  As a short video platform, Aauto Quicker has a huge traffic base. With the license of online small loan, Aauto Quicker may be involved in risk control and direct lending, and conduct consumer loan business in compliance through self-support, joint loan and loan assistance.

  When the reporter bought the goods in the "Aauto Quicker Store", he found that the payment methods include skip WeChat payment, bank card payment, Alipay payment and credit card installment, and there are no products such as first enjoy and then pay.

  According to Aauto Quicker’s recruitment of official website, Aauto Quicker recently launched the positions of product operation manager (financial industry) and financial industry sales in financial-related fields, and the online time was April 3 and March 27 respectively. Among them, the job requirements of product operation manager include "exploring the growth point of customer consumption according to different customer acquisition modes of financial credit products" and "planning and promoting the commercial operation of advertising around the financial industry".

  Total revenue increased by 20.5% year-on-year.

  According to the data of 2023 financial report, the total revenue of Aauto Quicker in 2023 reached 113.47 billion yuan, up by 20.5% year-on-year, and the adjusted net profit was 10.3 billion yuan.

  With the "short video+live broadcast mode", Aauto Quicker has formed a distinctive "old iron economy", which combines content with e-commerce through private domain traffic operation.

  According to the financial report, the GMV of e-commerce business in Aauto Quicker increased by 29.3% year-on-year in the fourth quarter of 2023, reaching 403.9 billion yuan, and the average monthly paying users of e-commerce reached a new high, exceeding 130 million, with the annual GMV reaching 1.18 trillion yuan.

  According to many media reports, Aauto Quicker executives publicly disclosed in 2023 that the number of users watching financial-related content on Aauto Quicker APP reached 160 million times per week, and the conversion rate of financial advertisements was 19 times that of ordinary users.

  As a short video platform, Aauto Quicker has a strong traffic advantage and content monetization ability, and its recommendation algorithm can match users’ interests more accurately, making the content easier to reach the target audience and improving the conversion rate.

  "Aauto Quicker’s users are large in scale and high in stickiness, and it has a certain foundation for its own diversion business. Traffic is its advantage. " Wang Pengbo, Chief Analyst of Broadcom Consulting,The reporter said that the advantage of the loan-helping business is that it has accumulated over the years and has a better understanding of the industry gameplay. The scene platform has users and funds, and it is easier to grow bigger.

  In the competition of consumer credit market, consumer credit platforms that enter the market early often have the first-Mover advantage, and build barriers by accumulating users and establishing user loyalty. When users get enough quota, the motivation to switch to other platforms will be less. Because there is an upper limit on users’ credit, once users get consumer credit on multiple platforms, it may lead to "co-debt problem".

  Su Xiaorui believes that as a short video giant, Aauto Quicker’s traffic advantage is second only to platforms such as Tik Tok, and B-side businesses such as Aauto Quicker Xiaodian have become increasingly mature. From the customer base type, the customer base in Aauto Quicker is relatively sinking, and this group of people is just the long tail customer base corresponding to small loans in the financial field, which has potential in customer base positioning and customer base demand mining.

  With the scarcity of high-quality investment targets in the industry, Aauto Quicker has potential in developing financial business because of its huge user base and traffic advantages. However, the so-called "platform users’ qualification is relatively low" means that the user groups in Aauto Quicker may include more users with low income and low credit rating or white households with credit information, and this group may have a higher risk of financial default. Therefore, risk control and asset quality management in Aauto Quicker may become challenges when developing small loan business.

  "Aauto Quicker-based financial genes are relatively lacking, and it is suggested that it should be based on compliance, and fully learn from other traffic giants in the financial field and other clues to avoid repeating the same mistakes." Su Xiaorui said.
