　　International Online auto channel News: A country’s prosperity and development can’t be separated from people who work hard for it. Since the reform and opening up, China has gradually realized the rise of a great country and the rejuvenation of the nation. Behind it are generations of enterprising strugglers who have gathered their strength and influenced and changed our times. On New Year’s Day, 2022, China Star, a high-end series of Geely brand CMA, joined forces with The Paper to launch a video short film of time portrait character recording — — "Dare to act, be the China star of the times", spread the voice of the times, and let the public better perceive and convey the spirit of "Dare to act".

　　"Dare to act" is the epitome of China’s courage to challenge and surpass itself. Under the background of great powers in the new era of dreaming, China needs more spirit of "dare to be a man" and "dare to act" to constantly challenge and break through. On the occasion of New Year’s Day in 2022, the film invited five "dare to be pioneers" in different fields — — Media person Yang Lan, China team male gymnast Xing Aowei, "Top Ten Most Beautiful Paramedics" Yu Yifei, legless warrior Xia Boyu who successfully climbed Mount Everest, and post-80s car boss Gan Jiayue have interpreted the spirit of "daring to act" in many dimensions through their oral statements and deeds, giving every ordinary person the power of the times: daring to act and being the China star of the times. At the same time, this is also the first time that Geely China Star released its "Dare to Do" value proposition during the 11th period of 2021, and once again took "Dare to Do" as the key word of the 2022 New Year, responding to the call of the spirit of the times and playing the strongest voice of the times.

　　In the name of "dare to act", the China stars of the times shine.

　　Every era has its heroes, and every era has its "China Star" that shines on it. Today’s China has a prosperous culture, flourishing science and technology, and prosperous city. Behind the development of the times, there are countless "China stars" emerging from all walks of life. These people dare to challenge, explore, innovate, take the lead in the world and constantly lead the times.

　　The five "dare to be pioneers" in this film, whether athletes, mountaineers, doctors, media people and autobots, have all made contributions in their respective fields and played a leading role in social stability, economic development and a better life with the spirit of "dare to act" such as persistence, responsibility, struggle, exploration, breakthrough and innovation. The film tells the life stories of these five China stars and their understanding of "dare to act", and interprets the "dare to act" spirit of the times with the "dare to act" spirit of the characters.

　　At the end of the film, Geely Automobile’s first post-80s CEO— — Gan Jia read a monologue from a representative of the national automobile, telling the enterprising spirit of Geely Automobile and explaining the persistence and innovation of the national automobile industry. Finally, Gan Jiayu, together with other big coffees from all walks of life, deepened the spirit of "daring" of the times, and said in the film, "The most beautiful scenery in China is the 1.4 billion enterprising people in China, and the most powerful force of the Chinese dream is the gathering of thousands of strugglers in Qian Qian".

　　Geely Automobile’s "Dare to Do" Road, Fighting for the Value of China Automobile.

　　At present, China has become the most important arena in the global automobile industry, hunting at home, with China as the leading force. As the global leader of China automobile, looking back on Geely’s 25-year car-making process, we will find that Geely has been breaking through and constantly innovating, which will eventually become impossible. Now, the dual export of power products and technologies to overseas high-end brands is realized. Geely Automobile has gone from weak to strong, from small mountain villages to the world, relying on the "dare to act" spirit of all Geely people. In mastering the core technology, we will spare no expense to invest heavily. In the decade of 2021, Geely will invest more than 140 billion in R&D, and research and develop whatever is not working. After five years’ development, Raytheon Intelligent Engine Hybrid has completely surpassed Japanese Hybrid in key technologies such as thermal efficiency and fuel saving rate, breaking the long-term monopoly position of Japanese Hybrid, and will realize "China Power Supply to the World" for the first time.

　　In addition, Geely is the only car company in China with four world-class modular architectures: CMA, BMA, SPA and Vast. Building a car with this architecture will ensure that Geely’s products always remain the world leader. The "China Star" series, which was born in CMA architecture, assembled all the best technologies of Geely at present, completely surpassed the strong joint venture brand products, and made the popularization of high-end products a reality.

Geely xingrui

　　"China Star" is a high-end series of Geely brand CMA released by Geely Automobile in 2021. At present, it includes China Star flagship SUV Xingyue L, China Star high-performance SUV Xingyue S and China Star flagship sedan Geely Xingrui. With the listing of Xingyue in 2019, it broke the inherent cognition of users’ distrust of the three major pieces of China cars; By 2020, Geely Xingrui will go public, breaking the long-standing China family car standard dominated by foreign brands; In 2021, Xingyue L went public and redefined the new standard of SUV. In the past three years, China Star’s three high-end series products built by CMA framework have formed the strongest flagship lineup in China.

Xingyue l

　　The mission of "China Star" is to bravely challenge the world’s mainstream cars on behalf of the China brand with the spirit of the times, fight for the value of China cars, and make China cars bigger and stronger. "China Star" series broke the habit of traditional independent brands and took "high cost performance" as the strategy, but really competed with other competitors with "high value". Since its release, "China Star" has won praise from the market and consumers by virtue of its product strength and high value far exceeding the joint venture brand. At present, the total sales volume of China Star has exceeded 200,000 vehicles. More than 60% of the users of China Star choose high-end vehicles, 52% of the sales volume of China Star comes from the demand for replacement, and more than 40% of the users have joint venture experience.

Xingyue s

　　Therefore, "dare to act" is not only the pioneering spirit of the pioneers who broke through the shackles and struggled forward, but also the important spiritual core of Geely Automobile’s development from a little-known private car company to a big country brand. In the film, Gan Jiayu said confidently that it is the responsibility and mission of China Autobots to fight for the value of China cars and let China cars travel all over the world. Now it is at the critical point from making cars to creating cars, which is the only way for China to become a powerful country from a big automobile manufacturing country. This road is difficult to walk, but it is precisely because it is difficult to walk that we have to walk, and more people who dare to think and dare to walk together.

Geely automobile

　　Everything in the past is a preface. When the bell rings in 2022, in the face of the changes of the times and the rapid changes in the world, only by daring can we climb higher mountains and achieve more brilliant achievements. As Gan Jiayu said at the end of the film, "In an era of courage, when everyone is thinking and working hard, no matter how difficult the mountain is, you can climb it and enjoy the beautiful scenery." Looking forward to the future, I hope that everyone in China can be bold and work together to promote the development of the new era. In 2022, together with 1.4 billion China people, we will dare to be the China star of the times. (Source: Geely Automobile)

　

　

　

Start, speed up, park…

Lu Zhaoming, an associate professor at Beijing University of Posts and Telecommunications, was sitting in a test vehicle in a parking lot 12 meters underground in the Xiongan New Area. He kept an eye on the position cursor on his mobile phone.

The test vehicle uses "5G + Beidou" positioning and navigation technology.At present, this technology has been demonstrated in Xiongan underground for more than 500,000 square meters, with a positioning accuracy of 2 meters, and the construction cost is only half of the traditional underground navigation technology.

Inspired to channel signals from the sky into the ground

Today, ever-advancing navigation technology makes people’s lives more and more convenient. But many people also have the experience that once they enter a building below the ground, the reinforced concrete will block the navigation signals such as Beidou "clean".

At the beginning of the planning of Xiongan New Area, it was proposed to build "an underground city".This includes about 380 kilometers of underground integrated pipe corridors and over 22 million square meters of underground parking. The precise management of the "underground city" requires high-precision positioning and navigation, and requires new technology and low cost, which can provide replicable samples for other urban construction.

"We compared all kinds of existing technical solutions, and the investment cost became an insurmountable’roadblock ‘," Zhang Qiang, secretary general of the Xiongan New Area Smart City Innovation Federation (hereinafter referred to as the "Innovation Federation"), told the Science and Technology Daily reporter. At the beginning of research and development, as the lead organizational unit for the research and development of underground navigation technology, the Innovation Federation tried almost all mature technical means –

Deploying Bluetooth point beacons in the basement has high construction costs and high operation and maintenance costs;

The addition of Beidou navigation base station indoors cannot afford the high cost of equipment.

Using WiFi positioning requires not only deploying WiFi access points, but also investing in a new network…

Is there a low-cost and effective technical route? Zhang Qiang and the project team members sat around and kept "brainstorming". Proposals, discussions, collisions… More than a week has passed, and there is still no solution.

One evening, the three members of the project team who had discussed nothing stood on the side of the road unhappily. Suddenly, an idea came to Zhang Qiang’s mind: Why can’t we "use local materials" and borrow existing communication facilities – 5G indoor distribution system?

The indoor distribution system is not mysterious, it is a small antenna that looks like a "small mushroom head" that people often see in the corridor or at the door of the house. In 2020, the Ministry of Industry and Information Technology made it clear that 5G indoor signals should be jointly built and shared. Telecom operators uniformly "mix" various signals into the key equipment – the combiner, and the standard 5G indoor signal is then distributed to each "small mushroom head" by the combiner. However, these "small mushroom heads" can only provide communication protection, not positioning and navigation.

"By the way, receive the Beidou signal and forward it with the help of the’little mushroom head ‘!"

This idea made everyone suddenly enlightened. Lu Zhaoming, who was invited to participate in the project team, recalled that in the past, everyone just made a fuss about communication, and no one thought of it.The combination of Beidou signal and 5G indoor distribution system has opened a new door for underground high-precision positioning and navigation.

"That night, I looked at the night sky, and the shadowy Big Dipper was particularly charming." Zhang Qiang said.

Breakthrough algorithms to achieve accurate underground positioning

Walking into the corridor on the sixth floor of the third teaching building of Beijing University of Posts and Telecommunications, Lu Zhaoming pointed to the line above his head and told reporters: "The experimental demonstration of ‘5G + Beidou ‘is carried out here."

The idea of fusing Beidou signals into a 5G indoor distribution system sounds simple, but the implementation process is full of challenges.

The first challenge is how to introduce the Beidou signal underground.In the 5G indoor distribution system, the three telecom operators’ respective 3G/4G/5G and other multi-channel communication signals are transmitted. If a Beidou signal is added, the original communication signal may be interfered, causing the mobile phone to be unable to talk and surf the Internet normally.

"At the beginning, there was nothing I could do. I could only start by analyzing the intermodulation interference model of the two signals and find the fusion algorithm of the signals." Lu Zhaoming said,Communication and Beidou are two types of signals, but they are not mutually incompatible "enemies".The team members calculated the filtering and power parameters required for the Beidou signal to be imported into the 5G indoor distribution system, and then successfully introduced the Beidou signal into the underground through the shared link transmission of broadband multi-channel signals.

The problem of Beidou signal introduction is solved, and the problem of navigation and positioning accuracy emerges.The accuracy of using Beidou signals for positioning outdoors is about 10 meters, but this accuracy is far from enough in the underground environment. Because the distance between two adjacent intersections in the underground parking lot is often less than 10 meters, if the accuracy is not improved, the positioning and navigation will inevitably be wrong.

"This problem has puzzled us for more than a year. During that time, we tried more than 100 different types of algorithms, but the positioning accuracy was not ideal." Lu Zhaoming said that one day, during testing, he accidentally discovered that the wireless reflection environment of Beidou signals in space has static characteristics, which can be used to build data models and provide more location observation sources.

Although the single information of each end point in the parking lot is not accurate, the multi-party information is collected together, and the positioning results will become more and more accurate through the continuous collaborative calibration of the data model.The positioning and navigation strategy was upgraded from "individual combat" to "multi-end point cooperative combat", and a set of positioning algorithms with independent intellectual property rights was born.

In June 2022, in the underground parking lot of Xiongan New District, when Lu Zhaoming saw the positioning cursor move step by step on his mobile phone screen for the first time, he jumped up excitedly.

"This proves that our positioning algorithm and scheme works in actual scenarios!" Lu Zhaoming said.

Pioneering equipment, twisting the "bull’s nose" of independent innovation

In Xiongan New Area, the reporter took a car through a downhill "entrance" and "plunged" into the underground parking lot of Xingqiuyuan in Rongdong District. The navigation map on the mobile phone switched instantaneously, and the arrow guided the vehicle to find the parking space accurately.

In the parking lot, there was neither intricate wiring nor communication equipment crawling all over the wall. There was only a computer room less than 10 square meters at the corner of the passage, and a large amount of equipment was "hidden" here.

"We are’underground workers’," Chu Xinghe, a postdoctoral fellow at Beijing University of Posts and Telecommunications and a member of the project team, told reporters with a smile. Since the experimental verification, the R & D team has spent more than a year debugging and improving equipment underground.

"Here, you must not’judge things by their appearance ‘." Chu Xinghe introduced,Although only a few small boxes are placed on the wall of the computer room, they are like the "heart" of the underground navigation system.The combiner, 5G indoor distribution unit, and Beidou indoor distribution unit rely on these core devices to successfully import Beidou signals and send out positioning signals.

Among these devices, the Beidou indoor distribution unit is the first in the world.The Beidou satellite signal comes to the ground from an altitude of more than 20,000 kilometers, and the signal strength is extremely weak. If it is introduced into the underground computer room, the signal strength will be further attenuated. The project team innovatively developed the receiving module of the Beidou indoor distribution unit, which can amplify the Beidou signal, support feeder transmission up to 1 kilometer, and introduce high-quality signals into the ground.

"The core components in the unit have completely independent intellectual property rights. It can filter the complex signals received layer by layer, remove useless signals, enhance useful signals, and block malicious attack signals to ensure navigation safety." Chu Xinghe said.

In May this year, the Supreme Leader General Secretary pointed out during his inspection of Xiongan New Area that efforts should be made to build a three-dimensional comprehensive transportation network, make full use of underground space, and strive to create a future city without "urban diseases", and truly turn a high-standard urban planning blueprint into a high-quality urban development reality picture.

"In 2025, the ‘5G + Beidou ‘navigation will cover all the built underground parking lots in Xiongan New Area, truly realizing the navigation of’an underground city’."Looking to the future, Lu Zhaoming was full of expectations, "We hope that this technology will be applied to more scenarios such as mining areas, transportation hubs, terminals, etc., and play a greater role in making full use of underground space!"

Hua Qiangu Yaoshen Makeup is stunning – she is not the only beauty whose style has changed

　　The heroines of costume dramas are mostly ill-fated and have experienced many storms. So, how does the same actor want to show the ups and downs of the heroine’s fate, or even interpret the character’s life by one person? The answer is – "makeup".

　　Hua Qiangu – Young Girl to Dementor

　　In costume dramas, the role of the female protagonist’s makeup is more prominent than in modern dramas. Take today’s "Hua Qiangu", which has received a lot of attention, as an example. Xiaogu has gone from an ignorant girl to a long-term study, from respecting the first apprentice to exile in the wilderness, and now to the birth of the demon god. In this ups and downs of the plot, she has to rely on different makeup to express the characteristics of each stage.

Ignorant girl at the beginning of the world

　　Ignorant girl at the beginning of the world

　　Hua Qiangu, who had just grown up, was brutally ostracized by the villagers, but she still maintained a kind heart. At a young age, she had hardly applied Fendai, but her eyebrows had been modified. It was the most popular horizontal eyebrow so far this year, and it was also to show her stubborn and unyielding character.

Long-term learning and artistic love are just beginning

　　Long-term learning and artistic love are just beginning

　　When she arrived at Changliu to learn art, Hua Qiangu practiced hard in order to become an apprentice of His Majesty. Because she had a goal to strive for and knew her admiration for Baizi’s paintings, she always had a crimson color on her cheeks at this stage. Eye makeup was also matched with it, and the eyeshadow was mostly light pink, like a girl who was just beginning to fall in love.

Become the first disciple and become domineering

　　Become the first disciple and become domineering

　　Becoming the first disciple of Baizi’s painting, Hua Qiangu was satisfied, and with the improvement of her cultivation, she gradually showed a hint of domineering. Although the makeup style was not significantly different from when she first entered the long stay, looking at her calm expression stroking the Liuguangqin revealed firmness and determination.

In order to save the master, he risked his life

　　In order to save the master, he risked his life

　　For Hua Qiangu, Bai Zihua was poisoned by the incomprehensible Bu Yuanding. As for Xiao Gu, who forcibly collected 10 divine artifacts to save his master, he was accused by the Immortal Realm and was seriously injured. Hua Qiangu’s face was pale and his lips were completely bloodless, looking very weak.

Cast the Great Cross Exile into the Wild

　　Cast the Great Cross Exile into the Wild

　　Little Bone made a big mistake by stealing the artifact without authorization, and was found to be in love with her master by the pool of unfeeling water, and suffered disfigurement. At this time, Little Bone was physically and mentally exhausted, mistakenly thinking that Bai Zihua had ordered her to be exiled to the wilderness. With pain all over her body, as well as pain in her heart, Hua Qiangu struggled to survive in the wilderness. At this time, in addition to a large scar on her face, the makeup artist also used dark makeup to create a dark yellow complexion without any trace of blood. And in terms of eye makeup, the dark purple with pearlescent effect made her look swollen and lifeless.

The charm of the demon god is unstoppable

　　The charm of the demon god is unstoppable

　　Little Bone broke through the seal and finally became a demon god. At this time, her style changed, and from the beginning of the young girl, she became charismatic and unstoppable. Her eyebrows were elongated and raised diagonally, and her aura was bursting. Thick black eyeliner with blue eyeshadow gradually changed, looking extremely cold. The red lip makeup is sexy and coquettish, echoing the red demon god mark on the forehead, there is a kind of invincible domineering without anger and arrogance.

Zhen Huan – Young girl to powerful Empress Dowager

　　Zhen Huan – Young girl to powerful Empress Dowager

　　In "Empresses in the palace", Zhen Huan entered the palace at the age of 17 and eventually became the empress dowager. After decades, Zhen Huan’s makeup also evolved from pure and elegant at the beginning to vicious and sharp at the end. The change of makeup is also like Zhen Huan’s heart, from innocent with no dispute with the world to cold with revenge.

Entering the palace for the first time – delicate and elegant

　　The first time you enter the palace, you are delicate and elegant

　　After entering the palace for the first time, Zhen Huan’s makeup was elegant and pink, and the curved light-colored eyebrow makeup was soft and simple. The fine upper eyeliner outlined the eyes of God, and the curled eyelashes were modified to make the eyes more sweet. The pink eyeshadow was tender and pleasant, indicating the arrival of peach blossom luck. The pink lip makeup was also indifferent, and Qi Liu Hai’er correspondingly showed Zhen Huan’s simple girlish heart, as cute and pure as peach blossoms.

Revenge Stage – Cold and Shrewd

　　Revenge stage is cold and shrewd

　　After being framed and exploited by intrigue, Zhen Huan at this stage had become a scheming woman and began to fight back coldly. Her fair base makeup made her still beautiful, and the rouge under her cheeks outlined a serious face. The eyeliner raised at the end of her eyes and the sharp eyebrows raised to the sides showed vengeance. The peach lipstick outlined beautiful lips like a danger warning, with a sharp and charming beauty.

Power and government – ruthless

　　The government is ruthless and ruthless

　　The revenge was successful, the queen was taken down, and Zhen Huan’s makeup, which had already mastered everything, also turned completely cold. The slender and sharp eyebrows, echoed by the raised eyeliner, gave the overall eye makeup a severe and fierce feeling, and the dark burgundy lip makeup showed the determination and ruthlessness of a strong woman. The orange blush lost its femininity, replaced by the courage of a powerful woman, which made people shudder.

Wu Meiniang – Soft and charming girl to domineering queen

　　Wu Meiniang – Soft and charming girl to domineering queen

　　Similar to Zhen Huan, Wu Meiniang’s life also went from ignorance to viciousness, and finally reached the peak of power. From the shyness and pure beauty of entering the palace at the beginning, to the beauty and allure of being favored, to the meanness and firmness of the palm of power at the end, the makeup also went from soft to sharp, from pink to dark red, showing Meiniang’s life trajectory step by step.

The girl enters the palace – soft and shy

　　The girl enters the palace soft and shy

　　The skin was so tender that it could pinch out water. Fan Ye easily interpreted a teenage girl entering the palace for the first time. Her elegant flat eyebrows, delicate and cute, and the upper eyeliner was simple and soft, outlining the simple eyes of the shy girl.

Being awarded Zhaoyi – Beautiful

　　Being awarded Zhaoyi is stunningly beautiful

　　The scene of Mei Niang being sealed Zhaoyi is a classic clip in "The Legend of Wu Mei Niang", and this look is called "too beautiful to be human" by netizens. Indeed, Mei Niang, who was favored by Li Zhi, once again stood firm and showed off her brilliance. The bright red lipstick matched the gorgeous clothes, which was beautiful and charming. The slender and elegant eyeliner was charming and alluring, and the red mark on the forehead showed a strong aura.

The pinnacle of power – gorgeous and domineering

　　The pinnacle of power is gorgeous and domineering

　　Meiniang, who had reached the peak of her full strength, was gorgeous and domineering, her slightly raised thick eyebrows were dignified and firm, and the large-area smudged eye makeup at the end of her eyes showed a strong aura and depth. The bright red lips and sharp lips were cold and attractive.

　

Do you know? In 1885, when the prototype of the car was just formed, the lighting system came into being. Perhaps you can’t imagine that the earliest lights were actually a pair of fuel lamps! At that time, cars and horses were expensive and letters were slow. But it was precisely from this era when even lighting the night road could not be satisfied that car headlights began their advanced path.

In the following century, acetylene lamps and incandescent lamps emerged one after another, and in the 21st century, automotive headlamps have made significant progress.

It is also because of the complexity of the traffic environment and the expansion of the urban development process, including people’s travel needs in bad weather. Better lighting effects such as xenon headlights and LED headlights have been transplanted to more and more models, becoming the main theme of automotive lighting.

Do you think this is the end of the development of car headlights? Shallow, what we want to talk about here is no longer limited to the progress of materials, but to rise to the level of technology lighting experience. What should the lighting experience look like in the era of intelligence?

When the headlights have been automatically turned on and automatically switched to near and far light, what else can it do?! It can also help you with high-beam keying, and can also help you show a wide-light blanket. It can also help you open a concert and watch a movie at a campsite. When the headlights have interactive functions, you will have the illusion that your understanding of the lights is too narrow? In the latest version of the M9 OTA push, the ritual-filled Kunpeng welcome and projection headlights outdoor Karaoke have been realized.

People-oriented technology will always make people feel warm in the details, and technology-leading brands tend to integrate more user-friendly functions in a linked way. When you approach a Q Jie M9 with your key, the distinguished welcome halo slowly lights up, and the headlights play out your preset pattern. Get in the car, adjust the headlights adaptively, and immediately enter the working state, because the next series of operations will allow you to immerse yourself and enjoy driving the Q Jie M9 freely through the streets and alleys.

Megapixel headlights high-precision ADB unique display, envy everyone

Take Beijing as an example, the number of motor vehicles has exceeded the 8 million mark, which is a very large group. Above the night sky, in addition to the illuminated night sky, there is also the surging traffic on the ring road. You are very disgusted with the harsh high beam shooting towards the lane, or the big cutie behind your car who has been driving high beam. Light is wasted or used in the opposite of the original lighting, hindering night travel safety (according to incomplete statistics, more than 40% of night traffic accidents are caused by glare).

No matter whether it is the person who drives the high beam or the person who is illuminated by the high beam, everyone does not benefit. Even the matrix headlights of some high-end models are clearly equipped with ADB (Adaptive High Beam) function, but the internal composition and the number of modules of the matrix headlights are not enough to support such a detailed cutout, and the shielding is too large for the area of passing cars/pedestrians, which often causes a large blind spot of vision and is prone to risk.

However! M9’s megapixel smart projection headlights use a megapixel module, and the dual lights can reach 2.60 million pixels. The shielding size of each pixel is only 0.02m, which is a hundred times higher than the industry’s 84 pixels. It can truly achieve lane-level precision control. Coupled with Huawei’s combination of intelligent driving perception and algorithms with headlights, the lights really become another pair of bright eyes for the driver and the car.

As a result, everything from a large car to a small person can be precisely reserved. Drivers can see the front clearly, other traffic participants will not blink, and the high beams will no longer disturb people! Therefore, black technology is not a solution. Whether it is used or not is the most direct way to show sincerity.

My headlights are a ruler! Easy in a narrow environment

Cars are not always speeding on city expressways, there are country roads at the end of the street and even to the camping site, you will see such a scene, only narrow aisles are left for parking, and there are limited-width concrete piers along the river embankment. You are about to pass carefully at night. If you are still driving a big guy, it is inevitable that the co-pilot will get out of the car to watch. The large screen of the M9 has such a button. After turning on the width indicator light blanket of the headlights, the light band of the pavement is slightly wider than the body. When you see that the light band does not shine on the obstacle, you can easily pass.

Summon Kunpeng? Awaken the instant ritual feeling full

Interesting people have their own halos, and so do interesting cars.

Imagine, as the owner of the car, you slowly walk towards the M9, and Kunpeng directly swims to the ground. Passers-by are attracted by your operation. The shape of Kunpeng’s wings also illuminates the surroundings of the door. Isn’t it a noble and intimate feeling? The well-known meteor shower effect can only be regarded as unremarkable in front of You Kun, especially when you summon Kunpeng through your mobile phone or watch, it will incarnate into the C position of the audience in minutes and attract much attention.

In the latest version, the tail lights of the M9 have also become richer. The previous red double, love and lantern shapes are just a small test, but they also add a touch of vitality to the cookie-cutter lights and boring car water Ma Long. Now, the addition of milk bottles, red flags, cakes, fireworks and other lights adds a new seasoning of technological fun to the mundane daily life, and also gives M9 owners more personalized emotional expression.

Summer night KTV, outdoor party? Projection headlights arranged for you!

The continuous explosion of self-media short videos has given ordinary people a side that they want to express themselves, but if I tell you that the distinguished Wenjie M9 can come with its own sky-breaking traffic, would you believe it?! As night falls, a curtain or a white wall can start to display. Turn on the megapixel headlights of the Wenjie M9 and directly project the lyrics. The effect is high-quality imitation of the mass-selling box. As soon as the verbatim lyrics leave, plus the opera house version of the audio playback, an open-air concert is immediately completed. With the microphone in hand, you are the master of this set!

In the era of smart cars, headlights have also been given more black technology, making the lighting system more visible. Intelligent lighting can help drivers get a safer and more convenient driving experience, and the realization of interactive and projection functions has become the icing on the cake, creating a richer social life and entertainment scene.

Compared to the almost demanding requirements of laser headlights, the practical significance of pixel headlights is more valuable, and the scene is also richer. For the future life, it may be the goal of the next OTA of the M9. What else do you want headlights to do? You might as well type it out in the comment area.

Wu Mengda

　　Looking back on the decades of Wu Mengda’s film career, there are almost no works in which he starred, which are typical supporting roles. However, compared with other full-time supporting actors, Wu Mengda is one of the few actors who have become popular in the Chinese area by acting in supporting roles. Many of his films have starred other movie stars, such as Jacky Cheung and Andy Lau, but most fans’ impression of Wu Mengda is still Chow’s films. Since 1990, Wu Mengda has been very successful by cooperating with Chow Xingchi, and has participated in dozens of Chow’s films, including 、、、、、、、、、 and so on. Among them, "Gambling on the Sage" in 1990 received more than 40 million Hong Kong dollars at the box office, breaking the box office record of a Hong Kong-made film in the past; in 1992, five films starring Chow Xingchi arranged the top five at the box office of the year, three of which were assisted by Wu Mengda; in 2001, he participated in the film again broke the box office record of a Hong Kong-made film in the past, collecting more than 60 million Hong Kong dollars. Over the years, he has cooperated with Chow Xingchi seamlessly and has been dubbed "Gold Green Leaf" by everyone.

　　In a turn of events, Wu Mengda, who is fighting again in this round of rivers and lakes, starred for the first time as the male lead in the groundbreaking new-school comedy "Big Shots". In the film, he played a TV person who was so down that he was drunk all day long. In the process of finding a livelihood, he helped to restore the luster of ancient memories. Stories of little people subverting ordinary lives are not uncommon, and their life comedy is the main theme of this film.

　　"When I was young, I also wanted to be the male lead, but at that time, the male lead was always Chow Yun-fat. I don’t know why I suddenly grew very old after the age of 30, and I didn’t look like playing the male lead, so I had to play the male lead’s father." Looking back at the time of filming, Uncle Da was a model worker, and he had no problem running five plays a day. "I have an average of two plays a month, and more than 20 plays a year. I haven’t slept for the longest six days. I just ran to Leung Chaowei’s side in the morning, went to Chow Yun-fa’s side at noon, changed to Dawn’s side in the afternoon, and returned to Xingzai’s side in the evening. The four heavenly kings all like to play with me, thanks to my mother, who gave me such a cute face."

　　Wu Mengda, an old actor who has played countless supporting roles, laughs that many of the characters can’t even remember himself. "Sometimes I look back at these plays and often say to myself, why was I so cheap back then!" Speaking of his current standards for new films, Wu Mengda said: "Don’t make cameos. There is an old Chinese saying, ‘I would rather be the head of a chicken than the queen of an ox’ means that you would rather be the head of a chick than the tail of a cow. It would have been a good thing to make a cameo in a big play, but I didn’t explain it to the audience. I just took advantage of your fame and had no special significance to the box office. It was just meaningful in publicity. I would rather make some small films and have my own performances. I would basically refuse those cameo roles." "I never cared about whether I was the protagonist or the supporting actor in the play, but one thing, there must be a play," Mr. Wu said frankly.

　　Wu Mengda, who is already a father in his life, believes that he is a good father from a certain perspective, "a good father in terms of taking care of children, but not in terms of time." Because he has been out filming all year round and spends less time with his children, Wu Mengda does not have time to accompany his children to grow up. He also said that if the child likes it, he will not oppose him from entering the entertainment industry. "But the child still needs to grow up, needs to study, and has enough wisdom to judge. This is a very complicated thing." In fact, Wu Mengda’s most wanted role is the father in "Wrong Ride", but he has never had the opportunity. "This father is dumb, has no dialogue, and relies entirely on acting." Wu Mengda laughed and said that because the play was purely tragic, people did not dare to ask him to act.

　　Think small and the world gets bigger; think big and the world gets smaller – for everyone.

Financial Investment Network News (Reporter, Liu Min)On February 21, Autonavi Maps’ integrated travel service platform was officially released at the seminar "Integration of scientific and technological innovation and reality to help build a transportation power". Autonavi Maps is the first batch of Internet platform companies to participate in the demonstration construction of a transportation power. The integrated travel service platform released this time is the result of its participation in the pilot construction of a transportation power.

Autonavi Map builds an integrated travel service platform in an aggregated model. At present, it has access to a full range of urban travel and intercity travel services, including urban travel services such as public transportation, subway, taxi, online car-hailing, walking, and motorcycles, trains, passenger transportation, airplanes, and other intercity travel services, as well as supporting services such as charging and refueling. Users can query real-time traffic information, plan travel routes, use navigation, taxi, shared bicycles, and other services. They can also directly buy train tickets, plane tickets, etc., which greatly improves travel convenience.

In order to promote ecological win-win and promote the integration of digital and real development. Yu Yongfu, chairperson of Autonavi Group, announced that the integrated travel service platform is Autonavi’s No. 1 project in 2023. Autonavi will adhere to the aggregation model, open up map navigation, technical services, platform traffic and other capabilities, and create a new combination with "old masters" who are deeply involved in the transportation industry to build an integrated travel service platform.

Integrated travel service platform released

The integrated travel service platform released by Autonavi Map this time provides users with a one-stop travel entrance, allowing users to optimize their individual travel experience, and provides integrated travel planning for the industry. It is based on Autonavi’s smart transportation and other technical capabilities to achieve global efficiency optimization.

It is understood that the platform is the stage result of Autonavi Map’s participation in the pilot construction of a transportation power. In 2021, the pilot work of the special project of building a transportation power comprehensive transportation big data was approved. Among them, Autonavi Map, as a pilot unit, and the Scientific Research Institute of the Ministry of Transport, undertook the pilot task of improving the convenience of comprehensive transportation services, becoming the first batch of Internet platform enterprises to participate in the demonstration construction of a transportation power.

At present, the Autonavi integrated travel service platform has been integrated into a full range of urban and intercity travel services through the aggregation model, including urban travel services such as public transportation, subway, taxi, online car-hailing, walking, and motorcycles, as well as intercity travel services such as trains, passenger transportation, and airplanes, as well as supporting services such as charging and refueling.

Autonavi cooperates with public transportation groups and subway companies in major cities across the country to provide users with real-time public transportation, real-time subway full load rate inquiry and other travel services; Autonavi cooperates with the taxi industry in more than 100 cities to help taxi network integration and online orders; Autonavi and Chihiro jointly launched the "Beidou Travel Application Innovation Plan", calling Beidou satellite daily positioning volume has exceeded 300 billion times, realizing Beidou dominance, and launching next-generation navigation services such as lane-level navigation and traffic light countdown.

In intercity travel, Autonavi cooperates with platforms such as 12306, Ctrip, and Flying Pig to provide users with travel services such as intercity route planning and ticket purchase. In terms of travel supporting services, Autonavi Map cooperates with more than 30,000 gas stations, covering 340 cities across the country. It also cooperates with State Grid, Telegram, etc., to achieve national coverage with more than 110,000 online charging stations.

Adhere to the aggregation model and fully open to the "master"

The construction of the Autonavi map integrated travel service platform requires not only the aggregation of all types of services to facilitate public travel, but also the aggregation of global enterprises to promote the integrated development of the transportation industry.

How the traditional transportation industry can play its strengths in the digital age is the key to promoting the integration of digital and real. Traditional transportation enterprises are like "old masters", with professional capabilities such as transportation organization, vehicle and driver management, and safety production. They are professional in the transportation industry, but they urgently need digital upgrades. Newcomers who are good at using new digital skills are like "new masters" representing new forces in travel.

Yu Yongfu believes that there are three ways to integrate data and reality in the transportation industry: new travel forces use new skills and become new masters; old masters invest a long time in self-learning new skills; the third is that old masters cooperate with enterprises with digital technology to quickly master new skills and form new combinations.

"A better choice for the integration of numbers and reality may be the third way. The old master partners with new skills, and the road to the integration of numbers and reality can go faster and farther," Yu Yongfu said.

Therefore, Autonavi Maps has listed the construction of an integrated travel service platform as the No. 1 project in 2023, adhering to the aggregation model, and opening up map navigation, technical services, and platform traffic capabilities for all types of transportation services and global enterprises.

As early as 2017, Autonavi pioneered an aggregation model in the shared mobility business, partnering with traditional transportation companies, cruise taxi companies, etc., to help them achieve digital upgrades and find new business growth points during the down cycle of the industry.

Autonavi data shows that under the aggregation mode, the ecological partners that provide ride-hailing services have experienced a compound growth rate of more than 100% in the past three years, and the peak order volume of more than 100 cooperative network ride-hailing platforms has exceeded 100,000.

"The success of an integrated travel service platform relies on deep aggregation, and the end result of aggregation must be an integrated travel service." Yu Yongfu mentioned that the integrated travel service platform deeply integrates multiple travel modes, providing users with a one-stop travel entrance, reducing travel thresholds, and at the same time allowing the ecosystem that provides travel services to deeply integrate and drive ecological win-win. This is the important significance of the aggregation model.

Aggregation model helps regional employment and economic development

The high-quality development of transportation requires the construction of a "safe, convenient, efficient, green and economical" transportation system. Through the aggregation model, the development direction of Autonavi has been in line with the development of the industry.

Under the guidance and support of the Beijing Municipal Transportation Commission and the Beijing Municipal Bureau of Ecology and Environment, public transportation groups, subway companies, and Autonavi Maps have participated in the joint construction of Beijing MaaS, becoming the first green travel integrated platform in China to provide "door-to-door" services.

Beijing MaaS is also the first in China to encourage users to travel green with carbon inclusion, and has reached the world’s first green travel carbon trading. As of now, the number of users participating in carbon inclusion on the Beijing MaaS Autonavi platform has exceeded 2.30 million. In 2022, the total carbon emission reduction of green travel on the Beijing MaaS Autonavi platform exceeded 200,000 tons, which is equivalent to the emission reduction of 100,000 fuel vehicles that have been suspended for one year. In addition, the second phase of carbon trading reached 97,600 tons, and all rights and interests were returned to the Beijing MaaS users participating in the green travel carbon inclusion.

The development of ecological partners in the aggregation model has also created new job opportunities and contributed to the economic development of various regions.

In Shenzhen, CCCC Travel, funded by the National Connecting Transport Alliance, has driven the digital transformation of road passenger transport enterprises. In August 2022, CCCC Travel orders increased by nearly 240% year-on-year, resulting in several new job opportunities.

In Beijing, Autonavi’s Beijing Taxi, a network integration platform in partnership with the Beijing Taxi Association, has helped drivers increase their income by 20% after going live for half a year.

In Jinan, in 2021, Timely Car will land its headquarters in Jinan to help the local headquarters develop economically. In order to provide large-scale online car-hailing services, Timely Car will purchase 20,000 new energy vehicles in 2022, bringing growth momentum to local automobile industry chain enterprises.

Similar stories of traditional travel companies leveraging digital technology to create win-win situations have emerged across the country. The aggregation model not only provides a catalyst for regional economic growth and creates new opportunities for regional employment, but also drives the industry into a positive cycle of service capacity upgrading.

According to the Hangzhou online car-hailing service quality evaluation organized by the Hangzhou Municipal Transportation Bureau, in the fourth quarter of 2022, the top three online car-hailing platforms with average monthly orders 100,000 above are all ecological partners that provide taxi services in the aggregation ecosystem.

Gesture-based user interfaces, if well designed, may be better than traditional button-based operations, especially on larger screens. Google introduced gesture-based navigation in 9.0 Pie as an alternative to traditional navigation bars. And in the latest Pixel 3 and Pixel 3 XL, Google went a step further and made gesture navigation its default and only option, which means that Android’s traditional three-key navigation method has disappeared completely.

On the Pixel 3 and Pixel 3 XL, users won’t be able to disable gesture navigation and opt for the familiar three-button scheme. Importantly, the decision also reflects Google’s overall Android plans for the future. In a response to a user’s question on Twitter, Google’s official @madebygoogle account tweeted: "The Pixel 3 introduces a new model that will represent the way navigation is done on all future Android phones."

This means that gesture-based navigation will become an integral part of Android in the future, not just on Pixel devices. Of course, given the open nature of the Android operating system, Google is unlikely to make it the only option.

That being said, many manufacturers, such as Samsung, OnePlus, Xiaomi, and Huawei, have started rolling out their own gesture-based navigation features with varying degrees of success. Looking to the future, we will definitely see more Android phone manufacturers offering gesture-based interfaces. We just hope that most Android UIs will still have the option to switch back to traditional button-based navigation.

Recently, citizen Xiao Zhang received a brand power bank presented by a cooperative enterprise, but the power bank clearly marked with a capacitance of 10,000 mAh charged the mobile phone once and then ran out of power. Recently, a reporter from Beijing Youth Daily found that many personalized power banks customized for enterprises online are counterfeit products, not only in the name of big brands in the market, but also falsely marked battery capacity. After dismantling these "counterfeit products" power banks, the batteries inside are rusty, and even some power banks use cement batteries.

The "big-name" power bank network sells for less than 20 yuan.

Like Xiao Zhang’s partner companies, many companies would choose to give customers power banks as gifts, and there were also many stores selling customizable and lettering "brand" power banks online. Through the introduction of these sellers, it can be seen that these power banks are called customized power banks because they can print text and patterns, and because the actual capacitance of these power banks can be customized.

In an online store labeled Shenzhen, there are 10 different styles of power banks on sale, many of which are used by some companies as gifts.

In this store, the reporter of Beiqing Daily chose a "Xiaomi mobile power bank" priced at 12 yuan and sold more than 100 times a month. The capacity in the product introduction is 10,400 mAh. From the pictures uploaded by the seller, the shape of the power bank sold is the same as that of the Xiaomi brand. The pictures of the product details used are also the product introduction of the Xiaomi power bank.

After clicking on the purchase button, a reporter from Beiqing Daily saw that options for capacity and logo customization appeared on the purchase page. Optional capacities ranged from 1,800 mAh to 4,800 mAh. Depending on the capacitor selected, the actual price would also vary, ranging from 12 yuan to 19.2 yuan.

In addition, buyers can also buy the packaging and wire corresponding to the selected power bank separately, the price is 12 yuan per set. If you order a large number of packaged power banks, the price of each set is 19 yuan.

After the reporter of Beiqing Daily chose to buy four more mainstream "brand" power banks in the store, he was told by the owner that the power banks photographed were "not for sale, but at least 100 for sale". After many negotiations, the owner agreed to increase the price and sell them separately.

Batteries are rusty
Disassembly sparks fly out

After getting the four power banks purchased, the reporter of Beiqing Daily compared the "Xiaomi Power Bank" purchased with the power bank sold by Xiaomi official, and disassembled the two power banks.

If you don’t look carefully at the appearance, there is basically no difference between "counterfeit products Xiaomi" and the real "Xiaomi". After careful comparison, it is found that the shell of the "counterfeit products Xiaomi" power bank feels rougher than the real "Xiaomi" power bank. The MI mark of "counterfeit products Xiaomi" can see obvious imprints, but the MI mark of the real "Xiaomi" has no imprints. The capacity mark of the tail power bank of "counterfeit products Xiaomi" is darker in color, and it does not feel like the real "Xiaomi" has a raised feeling. The URL of "Xiaomi" written on the back of "counterfeit products Xiaomi" is "xiaomi.com", while the URL written on the back of the real "Xiaomi" is "mi.com".

When a reporter from Beiqing Daily disassembled the two power banks, he found that "counterfeit products Xiaomi" are very easy to disassemble, and the internal components of the power bank can be pulled out by prying open the plastic cover at the top. The real "Xiaomi" has a closed part fixed by screws after prying open the plastic cover at the top. All the screws at the top and bottom must be removed before the internal components of the power bank can be pulled out.

After removing the shell, the circuit boards and batteries of the two power banks were completely different. The circuit boards of the "counterfeit products Xiaomi" were simple and the workmanship was rough. The batteries were wrapped in blue plastic.

After disassembling the plastic outside the batteries of the two power banks, it was found that there were obvious rust marks on the batteries of "counterfeit products Xiaomi".

During the dismantling process, sparks could be seen flying out of the battery anode of "counterfeit products Xiaomi" when it came into contact with metal items such as scissors.

Cement batteries are sold online for 0.24 yuan each.

In addition to the "counterfeit products Xiaomi" power bank, the reporter of Beiqing Daily also dismantled another common polymer lithium battery ultra-thin power bank, which mostly appears in the gifts issued by enterprises. Similarly, the workmanship of this counterfeit products ultra-thin power bank is also very rough, it is easy to be pried open, the circuit board is simple, and the packaging of the battery is only an extremely thin metal film. After the metal film is broken, the liquid overflows, and the taste is very pungent.

As early as 2015, Jiangxi Province had destroyed a power bank counterfeiting den, and the seized "counterfeit products" power bank contained 6 batteries, of which 4 were counterfeit filled with cement.

In various forums and Tieba, some netizens also discovered the "tricks" of inferior power banks, and some netizens disassembled the cement batteries in the power banks. From the disassembly pictures provided by netizens, the reporter of Beiqing Daily saw that some of the cement batteries were filled with sand, while others were filled with cement columns.

In some online shopping platforms, Beiqing Daily reporters found by searching for cement batteries that the price of pure cement core batteries is as low as 0.24 yuan each, starting at 100, and wholesale prices will be lower in large quantities. Some businesses selling cement batteries have power bank components and power banks working in progress.

At the same time, the Beiqing Daily reporter also found that many manufacturers have purchased 18650 batteries used in power banks online at a price of 1 yuan each, with a sales price of about 4 yuan. The price of genuine brand-new columnar 18650 batteries is around 10 yuan.

Low-quality batteries are dangerous
Easily cause fire

What exactly is a customized low-priced power bank battery sold online? The seller of the online store said, "The battery in the power bank he sells is a real battery, a product A battery, not a cement battery used for heavy charging, but a small capacitor, so there will be no short circuit, and long-distance transportation will not catch fire and explode."

Industry insiders told Beiqing Daily reporters that the batteries used in the power banks sold on the market are columnar 18650 batteries and flake polymer lithium batteries similar to mobile phone batteries, while some of the power banks made by "small workshops" use real batteries bought by Beiqing Daily reporters, but the power content is very small, and some use real batteries and fake "cement batteries" for mixed charging.

Generally, if a real battery is used, several batteries are connected together. If it is mixed and assembled, the cement battery will not be connected to the real battery. "The cement battery is placed separately and cannot be powered on when connected together."

The industry insider also said that most of the batteries in "small workshops" are made by the workshop itself or purchased from the outside world, and the safety cannot be guaranteed. If there is a problem with the columnar 18650 battery, it may cause a fire, "because the power content is small, although it will not explode, there will be flames in severe cases." And polymer lithium batteries, if the packaging is not good enough, once the electrolyte in the battery leaks, it will chemically react with the air, which will affect the human respiratory system, and ingestion will endanger the health.
