"It’s so interesting and happy to celebrate the New Year like this for the first time!" On February 9th, New Year’s Eve, the "1" in Chengdu’s "1+16+N" series of urban cultural activities made a lively appearance in Tianfu New District, Sichuan. Wang Liming, a citizen of Chengdu, was very excited to attend the event. That night, more than 10,000 tourists from all corners of the country gathered around Tianfu International Convention Center Square to experience the taste of Chengdu and have a happy year in Chengdu.

On New Year’s Eve, on the shores of Lake Qinhuang, lanterns are decorated and colorful, and the lively scenes are intertwined with the full popularity to create a strong flavor of the year. The theme of the event is "Walking on the streets of Chengdu, Welcome the New Year with Tianfu Picture Scroll", which is divided into four major activities and eight supporting activities, covering the "Tianfu Picture Scroll", the drone show, the iron flower show of the non-legacy fire dragon, the 1000-family reunion dinner by the lake, and the large-scale light show of "Hua Chong Jin Guan Non-legacy Lantern Festival Carnival".

"Serve, open the table!" As one of the key activities, the "Lakeside Thousand-Year Reunion Dinner" was grandly opened in the shouts of "running the hall". There were 168 square tables with a length of 100 meters lined up and 1008 guests were seated one by one. In addition to the 159 tables reserved by the citizens, the event organizers also invited family representatives who brought warmth and warmth to the city in 2023 to attend the dinner. Among them, there are Zhao Chunyan and his wife, the sign language interpreter Niu Niu and her family who moved the whole network, Wen Jun, the younger brother of Jingdong Express who rescued the paralyzed elderly in the fire, and Chen Xiaofeng, the "Hungry" takeaway who was brave enough.

The main course of each table is a big steamer. Uncover the red cloth on the cage, and the "nine bowls" familiar to Chengdu people appear-salted boiled pork, steamed pork, steamed elbow … There are sausages and bacon on the table that cannot be separated from the New Year’s Eve. The chefs on the sidelines are busy cooking mash and jujube beer for the guests. There was a strong smell of vegetables on the scene, and a warm taste of the year flowed during the dinner. While eating traditional food, the guests enjoyed Sichuan Opera’s programs such as changing face and spitting fire, money board, Niu Jiaoqin, Sichuan Opera puppet show and so on. Children also interact with performers and feel the charm of Chinese traditional culture during traditional festivals.

Another key event, the non-legacy dragon iron flower show, invited the dragon team from Tongliang, Chongqing. This team is led by non-genetic inheritors, dancing nine "fire dragons" with a length of 18 meters each. The most eye-catching key activity is the "Shining Rongcheng UAV Show", which consists of 3,000 UAVs, with a picture span of 800 meters. Customized pictures such as Longteng Sky, Furong Blooming and "Huahua" Happy New Year are very unique in Chengdu.

Relying on the tile roof of Tianfu International Conference Center, Tianfu Digital Long Screen Lighting, one of the four key activities, displayed a "Tianfu Picture Scroll" with a length of 408 meters and a width of 26 meters and a total area of about 11,000 square meters. The theme video "Flowers are heavy in Jinguan City, and thousands of weather are flourishing" was broadcast live.

In addition, the main venue also carried out eight activities, such as "New Year’s Blessing Lantern" and "Dragon Lantern Parade", which made a lively New Year’s Eve.

Traditional skill

10 minutes of non-legacy performance, so practice.

At 23: 15 on February 9, at the Qinhuang Lake, Chongqing Tongliang’s non-legacy fire dragon iron flower show came as scheduled, and the citizens and tourists who had been waiting here for a long time boiled up.

Nine "dragons" stood in rows in the performance area, and two huge "fireball" turned round, fast and bright, as gorgeous as fireworks. At the performance site, two artists stood by the hearth with a diameter of 40 cm and a height of 45 cm. One of them scooped up molten iron and threw it into the air. The other quickly scattered the molten iron with an iron plate, turned it into iron flowers all over the sky and flew into the dragon array … Nine dragons ran, and the 18-meter-long "dragon body" lit up and danced up and down. "Wow!" There were cheers from time to time in the crowd, and the performance attracted the audience to cheer while holding up their mobile phones, and the children were put on their necks by their fathers to get a panoramic view of the wonderful pictures.

Although the performance lasted only 10 minutes, it was very enjoyable and brought the audience the ultimate visual shock.

How did this "dragon" fly into Chengdu New Year’s Eve?

The person in charge of the intangible dragon iron flower show project said: "This year is the Year of the Loong, and the dragon dance project is very festive, and the custom of dragon dance in Tongliang has a long history. After we sent an invitation to each other, we received a positive response."

"I have performed in Chengdu before, but it is the first time to perform for Chengdu citizens on New Year’s Eve. We attach great importance to it." Li Chaoguo, chairman of Chongqing Tongliang Longren Shijia Dragon Lantern Art Co., Ltd. said, "In order to present a wonderful performance to Chengdu citizens, we spent more than 20 days making props and rehearsed for more than 10 days."

"The performance form is very contrasting," said the person in charge of the non-legacy dragon iron flower show project. On the one hand, the molten iron of thousands of degrees Celsius was scattered like a fairy flower after being hit, and on the other hand, the dragon dancers went shirtless in the dead of winter, which made people worry that iron flowers would hurt people. Li Chaoguo explained: "In fact, it is very safe. On the one hand, the molten iron has cooled rapidly when it falls from the air. On the other hand, the craftsman who hits the molten iron will break the iron flower so small that it cannot hurt people. "

Of the nine "dragons" that appeared that night, 110 people participated together. Not only that, Li Chaoguo and his companions also worked hard on the layout. Li Chaoguo introduced that the new "fireball" was used as the guide for the appearance of nine "dragons", that is, two iron baskets were tied with a long rope, which contained burning steel wool, forming a petal-shaped pattern in dancing, and the "dragons" were dispatched with meteors, which was very beautiful. Each "dragon" is 18 meters long and is danced by 10 people. The "Kowloon Dance" is spectacular, and many dragon-shaped arrays such as "Dragon Dance for Nine Days", "Crossing the River" and "Raptors Crossing the River" make the momentum even more majestic.

Creative technology

3,000 drones shine in Rongcheng

On New Year’s Eve, with the orderly launch of 3,000 drones, the finale program "Shining Rongcheng UAV Show" at the main venue was staged in the long-awaited eyes.

"Every pattern is performed by 3,000 drones. The scale of participating drones is the largest in Southwest China, and the difficulty is unprecedented, reflecting the strong Sichuan characteristics." The person in charge of the drone show project said.

On Hanzhou Road, Tianfu New District, Sichuan, a long team of drones is arranged on the road, flashing colorful lights. With the dispatch and operation of the flight command team, all the unmanned aerial vehicles (UAVs) took off, showing a picture of "Dragon in the sky"-a dragon ball in front, the dragon head flying with the dragon ball, the dragon body, claws and tails dancing slowly and vividly …

Subsequently, the drone team changed rose hibiscus flowers in the air, which attracted applause from the audience. After a short adjustment, buildings and streets gradually appeared in the air, and a picture scroll of the city slowly unfolded. "Park City under Snow Mountain, Happy Chengdu in Fireworks", two rows of words flashed in the night sky, which is exactly the happy home created by Chengdu people. Suddenly, cheers were everywhere.

The phoenix spreads its wings, and the divine bird turns. In the golden gear, the countdown to the Year of the Loong New Year is approaching second by second … New Year’s Eve is spent in such a wonderful experience.

How did the idea of dragon and phoenix dance come into being? How did the design and performance team do it?

According to the person in charge of the UAV show project, after receiving this task, combined with the cultural characteristics of Chengdu, the design team put forward many ideas and integrated Chengdu elements into it. The team of more than 20 people revised more than 10 drafts in one month. "Considering that the maximum power consumption of the drone battery cannot exceed 22 minutes, we have simplified the theme screen."

Liu Cairui, the head of the drone company that undertakes the performance task, said that a small drone is about 45 centimeters long and weighs about one kilogram. When designing complex action programming, the most important thing is the safe distance between drones. In the first picture, "Dragon in the Sky", a series of movements changed greatly and the rhythm was tight. It was rehearsed many times in 3D modeling, and the exact position of each plane was calculated repeatedly, and it was confirmed after assembly many times.

The picture of the giant panda "Huahua" greeting the New Year is also very recognizable. In order to make the audience recognize this as "Huahua" at a glance, the designer specially went to chengdu research base of giant panda to observe "Huahua" and collected a large number of videos of "Huahua" to study its physical features and manners, and finally locked the identification code of "Huahua".(Reporter Zhang Hongxia wrote)

The new car as a whole follows the design of overseas models and has been declared by the Ministry of Industry and Information Technology.

　　The new domestic BMW 5 Series long wheelbase version has been declared by the Ministry of Industry and Information Technology. The new car basically continues the design of overseas models. Compared with the current BMW 5 Series, the front face is more tough and looks dynamic and powerful. The new car will be equipped with a ring-shaped grille and boomerang daytime running lights as the latest design of BMW brand, but the giant "big nostrils" design of BMW 7 series is not used, and the overall shape is relatively restrained.

　　Semi-hidden door handle flush with the door, flat roof antenna make the side of BMW 5 Series look smoother, and the iconic "Hough Corner" of the rear door is integrated with the C-pillar. This idea is reflected in the current BMW 3 Series and 7 Series, and BMW has also added the details of the embossed number "5" on the black plaque, which is self-evident.

　　The obvious change in the tail is the lamp group, which adopts simple horizontal lines, making the visual effect more slender and exquisite, and redesigns the cover to better fit the vehicle shape on the profile. According to the application information, in terms of body size, the length, width and height of the new car are 5175/1900/1520mm and the wheelbase is 3105mm respectively.

The applications on the menu can also be adjusted according to the user’s usage habits and preferences.

　　In terms of power, the new 5-Series fuel version is equipped with a 2.0T inline four-cylinder turbocharged engine and 48V light mixing technology, with a maximum power of 190 kW and a peak torque of 400 Nm. The previously declared 525Li version has a maximum power of 156 kW.

◆ Edit comments

　　Although the appearance and interior of the new 5 Series are not amazing, the latest family design language passed down by it still gives the new car a strong BMW brand atmosphere. At the same time, the new BMW 5 Series is still built on the CLAR platform, which has the strategy of dual-track of oil and electricity. The platform can simultaneously derive the fuel version and pure electric version of the same car. The new BMW 5 Series based on CLAR platform still pursues BMW’s traditional 50:50 front and rear weight ratio, which puts the handling in a very important position.

　　It is worth mentioning that, according to previous information, the domestic current BMW 5 Series will be completely discontinued after November, of which the 5 Series standard wheelbase version (G30) was discontinued in June, the plug-in hybrid version (G38 PHEV) was discontinued in September, and the 5 Series long wheelbase version (G38) will be officially discontinued after November, that is to say, consumers can still buy BMW 5 from December.

Time to market: March 2024

"『N Line version; Ordinary edition "

　　It can be seen that Beijing Hyundai’s new Sonata, which was unveiled at the Guangzhou Auto Show, is basically the same as the overseas version, except for fine-tuning the details and high overall recognition. As an understanding, the Sonata currently sold in China is the tenth generation model, which was launched in July 2020, and will become the eleventh generation model with the domestic launch of the car in the future.

　　It is worth mentioning that the modern Sonata once enjoyed great popularity in the domestic market. As early as 2002, the fifth-generation Sonata opened the door to China, and then the eighth-generation Sonata, which was launched in 2011, reached its climax. At that time, its market performance even lost to competitors such as Magotan and Camry. However, since then, the two generations of products have gradually declined. It has been reported that the 11th Sonata will become the last generation product due to the sluggish market performance. So do you think the new Sonata will be successful this time?

◆ A new generation of Toyota Camry
Time to market: March 2024

　　According to what we learned at GAC Toyota booth, the new generation Camry will be listed in March 2024 at the earliest. The car is built on TNGA-K platform, and the local design is adjusted for the domestic market. According to different configurations, a total of three exterior shapes are launched, which have distinct style differences and meet different aesthetic needs. It can be seen that the new car is built with the latest design ideas of the brand, but some traditional elements have also been continued, such as the layered front face design and the overall design style of X shape. It can be seen that the differences between the three different versions of the car are mainly concentrated in the front grille of the "big mouth", one is designed for the honeycomb grid, which highlights the sense of movement; The other is designed for diamond elements, which looks more exquisite. Of course, the most sporty XSE models mainly add sports kits on the basis of SE styles to enhance the sports style.

In addition, the sports version is equipped with a unique sports style rim. At the same time, the XSE version adopts a roof design different from the car body to create a suspended visual effect, which can be said to accurately hit the preferences of young users. At the same time, it will also provide a 19-inch rim to further create a sports atmosphere.

　　It is understood that the new Camry will be equipped with a large-size central control screen and a full LCD instrument, which is in line with the current mainstream design. In terms of security configuration, the new Camry will come standard with Toyota Safety Sense 3.0 Zhixing Security Suite.

According to the official introduction, the new car has also made a lot of efforts in handling, vibration filtering, sound insulation and so on, hoping to bring users a more advanced driving feel and lower car cost.

◆ Edit comments

　　We can see that the new generation of Toyota Camry launched three styling designs for different configurations as soon as it came up, which can be compatible with users’ wider aesthetic demands. It can also be said that the new generation of Camry is quite well prepared. For consumers who have been looking forward to its listing for a long time, such sincerity should not disappoint everyone. At the same time, the replacement model has greatly enhanced the competitiveness of Camry, with new highlights in all aspects and strong attraction.

　　However, it is worth noting that in the domestic market, after the new Camry is listed in the future, it will not only have old rivals such as Accord and Teana, but also face the pressure from the price of luxury brands. At the same time, China brands, new forces and other models will also squeeze this part of the market share. Fortunately, even if the design of the replacement Camry is more avant-garde, it is still the same Camry, and its practical and reliable nature remains unchanged, which can still impress many people.

For products suitable for cross-border e-commerce, we should also pay special attention to the treatment methods in off-season and peak season, and the principle of product selection must not be forgotten, such as volume, weight, type and so on. Therefore, the principle is that the parts are small, light and not easy to be damaged.

The pace of modern life is fast, and the mobile phone is dying without electricity. There are many ways to charge mobile phones. What is yours, my friends? Can’t you play without the data cable? Or wireless charging on the tall? Move with the small number. What’s your posture?

1、USB Type-C

The biggest advantage of USB Type-C is that both sides can be plugged in. Xiao Yi is always annoyed that the interface of the mobile phone charger must be inserted according to its interface shape. Every night, she is sleepy and has to wake up before she can plug in the charger. The file transfer speed of USB 3.1 standard interface is also improved. However, at present, many mobile phones using USB Type-C interface adopt USB 2.0 standard. Although the appearance is Type-C, the file transfer speed is the same as before, and the charging speed has not changed.

The charging speed of a mobile phone depends on the charging current limit. Under the voltage of 20V, the upper limit of USB Type-C can reach 100w, but most mobile phones are limited to 18W-24W. USB Type-C can charge quickly, but it is limited in practical use. Even if the charging speed is unchanged from the traditional one, are there some friends ready to move?

2. Wireless charging

The biggest advantage of wireless charging is convenience, just put the mobile phone on it. The disadvantage is that the charging speed is too slow, about 20% slower than the traditional interface charging, and the friends must accurately place the mobile phone on the wireless charging base to charge. The fever of the mobile phone is also obvious when charging wirelessly. In addition, the cost of wireless charging is much higher than that of ordinary chargers. Small move is yearning for this tall, it is really reluctant to give up money.

Fast charging is a great technology developed recently. Little friends may be curious. Although it is fast, what impact will it have on the battery?

If the pro’s mobile phone battery supports fast charging and uses the official charger, then the battery will not be affected by fast charging. However, if friends use fast charging to charge ordinary batteries, it will seriously damage the battery life: fast charging depends on special components on the charger and chips on the mobile phone, and the two must be matched to ensure that current can be injected into the battery quickly and safely.

4. Fast wireless charging

At present, there are not many models that support wireless charging, and even fewer support fast wireless charging, but fast wireless charging technology has both the speed of fast charging and the convenience of wireless charging. Compared with wireless charging, its charging limit can reach 15W, which is three times as fast as that of ordinary wireless charging, and its charging speed is 50% faster. But at present, only a few models on the market have this function.

Little friends are envious of wireless charging, but they are more eager for fast charging. This is not impossible. Small move to popular science, look, the new material is revealed, and the fast charging battery material-graphene.

What are the advantages of graphene?

Graphene will replace silicon and create a brand-new era for the world’s electronic technology! The charging time of graphene mobile phone is only 5 seconds, and the battery is full, which can be used continuously for half a month! The graphene battery only needs to be charged for 10 minutes, and it is possible for an environmentally friendly and energy-saving car to travel 1000 kilometers!

Graphene is a two-dimensional crystal with only one atomic thickness, which is separated from graphite and composed of carbon atoms. Graphene is both the thinnest material and the strongest material, and its breaking strength is 200 times higher than that of the best steel. At the same time, it has good elasticity, and the stretching range can reach 20% of its own size. It is the thinnest and strongest material in nature at present. If a hammock is made of graphene with an area of 1 square meter, its own weight is less than 1 mg, and it can bear a one-kilogram cat. At present, the most potential application of graphene is to become a substitute for silicon, to make ultramicro transistors and to produce future supercomputers. Using graphene instead of silicon, the computer processor will run hundreds of times faster. Think about it, friends. How about this thing instead of the cell phone battery material?

Summary: Which charging method is the best?

Xiao Yi said: It depends on the attitude of friends to the battery. If parents want to extend the battery life, I suggest you choose a traditional charger. If you want to save trouble, you can choose a wireless charger. If you only pursue speed, you can choose fast charging or USB type-C. If you are preparing to buy a new mobile phone and at the same time pursue the best charging experience (if you are not short of money), you can find out which terminal supports it.

　　The demand for transportation has increased, and the flow of people and cars in urban areas has increased significantly; Restaurants and restaurants have resumed one after another, and the passenger flow in major business districts has increased; The number of tourists in popular scenic spots has rebounded, and the cultural tourism market has shown a recovery trend … … During the New Year holiday, the reporter learned that with the acceleration of resumption of work and production in many places, the life service industry resumed in an orderly manner and market consumption continued to pick up.

　　Driven by catering and retail, many key business districts began to be lively. In the Tianhe Road business district in Guangzhou, which is known as the "No.1 business district in South China", the daily average flow of people continues to recover. The reporter learned from Tianhe Road Chamber of Commerce that the number of people in the business circle exceeded 1 million on the day before New Year’s Day, and more than 100 events were held in various shopping malls around creative arts, national culture, fantasy travel and Tianhe fashion, which attracted many consumers’ experiences.

　　While offline consumption is gradually recovering, online consumption continues to be hot. Take catering as an example. According to the data of Meituan, the online transaction volume of dining hall food in China more than doubled compared with last week two days before the holiday, among which the related transaction volume in Jiangsu and Zhejiang increased by over 230%. In the past week, the sales of "New Year’s Day", "New Year’s Day" and "New Year’s Eve" themed dishes on the public comment list increased by 664% from the previous week.

　　The enthusiasm of consumers has also ignited the confidence of businesses. According to the data of Meituan, during the New Year’s Day, the number of take-away merchants offering New Year’s dishes increased by three times compared with the previous week, and the number of New Year’s related dishes increased by five times.

　　The reporter noted that in order to help the consumer market continue to recover, many places have introduced relief measures and consumption promotion arrangements, among which catering, retail and other service industries have become the focus. For example, the Ningxia Department of Commerce said that it should seize the peak consumption season at the end of the year and the beginning of the year and vigorously promote and hold various consumption promotion activities. Focus on automobile, catering, retail and other key industries, intensively and accurately release government coupons, and do a good job in subsidy payment. At present, the major business districts in Ningxia have fully resumed business, and the passenger flow in shopping malls is increasing day by day.

　　The increase in orders and the increase in the consumption of cultural tourism.

　　Consumer markets such as tourism, leisure and entertainment are also warm and harmonious.

　　During the New Year’s Day, many resort hotels in Sanya, Xishuangbanna and Zhangjiakou Chongli welcomed full rooms. Pullman Sunac Resort Xishuangbanna has a total of more than 400 rooms. One week before New Year’s Day, the popular rooms for the holiday have been snapped up. "Compared with previous years, the stay time and consumption items of guests in the hotel have increased significantly this year." The relevant person in charge introduced.

　　A number of data show that during the New Year’s Day, the popularity of transportation, travel and consumption has been rising.

　　According to the data of FlightAI market insight platform, during the New Year’s Day, major airports basically recovered to the same period of last year, and the passenger traffic of TOP10 airport increased by about 20% year-on-year. According to the data of Flying Pig, the number of train tickets during New Year’s Day increased by more than 2.6 times compared with the same period of last month, reaching the peak in the past six months, of which the inter-provincial train ticket bookings accounted for nearly 60%.

　　The signs of recovery in the tourism market are more obvious. According to the data center of the Ministry of Culture and Tourism, during the New Year’s Day holiday in 2023, there were 52,713,400 domestic tourist trips, up 0.44% year-on-year, and the domestic tourism revenue reached 26,517 million yuan, up 4.0% year-on-year.

　　According to Ctrip’s report, compared with less than 40% of users traveling across provinces in 2022, nearly 60% of users choose to travel across provinces during the New Year’s Day holiday this year. According to the data of the US Mission, the popularity of night play has not diminished, and the New Year’s Eve tickets for characteristic blocks and theme parks have increased by more than 10 times from the previous month. On the flying pig platform, during the New Year’s Day, the number of car rental bookings in popular tourist cities increased by more than three times compared with last month; The number of rooms reserved for star-rated hotels and country houses has increased by over 30%.

　　In addition, in terms of leisure and entertainment, with the orderly opening of cinemas across the country, the box office data of New Year’s Day movies is improving. According to the real-time data of Lighthouse Professional Edition, as of 13: 59 on January 2, the total box office of New Year’s Day in 2023 (December 31-January 2) exceeded 500 million yuan.

　　Recently, the Ministry of Culture and Tourism said that for winter tourism, especially holiday tourism such as New Year’s Day and Spring Festival, efforts will be made on both sides of supply and demand to accelerate the recovery of tourism consumption vitality.

　　Beijing Municipal Bureau of Cultural Tourism launched a new brand of "Beijing Micro-vacation" cultural tourism, and jointly released the first batch of six Beijing micro-vacation destination brands with relevant districts; Shanxi, Luoyang, Henan and other places have launched activities such as ticket concessions and ticket reduction and exemption; Hainan held the Happy Festival of Hainan International Tourism Island in 2022 and distributed 10 million yuan of tourist coupons to the whole country … … Many places have come up with "practical measures" to add strength to the recovery of the cultural tourism market.

　　"New vitality" generate’s service industry recovery can be expected

　　Recently, the the State Council executive meeting deployed a package of policies and measures to stabilize the economy, which achieved results, and promoted the foundation of economic consolidation and stability to keep running in a reasonable range. In terms of service consumption, the Standing Committee of the National People’s Congress proposed "promoting the orderly recovery of service consumption in combination with reality."

　　Industry experts believe that with the gradual recovery of production and living order and the effective implementation of relevant measures, service industry consumption is expected to accelerate recovery.

　　Fu Jiaqi, statistician of the Department of Foreign Trade and Economic Cooperation of the National Bureau of Statistics, believes that with the implementation of measures to further optimize the epidemic prevention and control, the series of policies to expand domestic demand and promote consumption have gradually taken effect, the development resilience of the consumer market has continued to emerge, and the consumer demand of residents will continue to be released.

　　"It is expected that there will be obvious recovery growth in the life service industry in 2023. In terms of consumption content, there is a large room for growth in catering and travel. In terms of consumption patterns, more attention is paid to the combination of online and offline consumption. In the consumer group, the youth group is full of consumption vitality and will become the main force for the innovation and development of service consumption. " Tamia Liu, deputy director and researcher of Market Economy Research Institute of the State Council Development Research Center, told reporters.

　　Service enterprises and related industries are also actively exploring ways out. Taking the catering industry as an example, Yang Liu, president of China Cuisine Association, pointed out that fast food enterprises should correctly and objectively understand the current development environment and their own problems, improve efficiency, reduce costs, scientifically and completely establish and continuously improve their own development models, actively try digital means, improve products and services, expand output value, gain more market space and explore better profit models.

Special feature of 1905 film network "I was born to be useful, spin a thousand pieces of silver, all of them come back!."With the impassioned recitation,li pofamous literary pieceInvitation to WineOn the big screen, it turned into an unconstrained visual spectacle, which made people fascinated and shocked.

The new film "Three Wan Li in Chang ‘an" starts from the first Tang poems, and takes the audience back to the bright times when the stars shone thousands of years ago. With the friendship between Gao Shi and Li Bai spanning decades as the axis, it outlines the magnificent group image of the stars in the Tang Dynasty.

The film has a good reputation in the screening stage. As the pioneering work of the "New Culture" series, it is expected to become the next summer animation explosion.

In an exclusive interview with 1905 Film Network, directors Xie Junwei and Zou Jing told us that they hoped to present the Tang Dynasty in an all-round way from the perspectives of scenery, character modeling and etiquette paradigm, and to awaken the cultural genes flowing in the blood with 48 Tang poems and familiar names to convey the romance unique to China people.

"Chang ‘an is an ideal place for poets, and’ Three Wan Li’ is the distance between them and the ideal, and it is also the distance between us and the ideal. Poetry is there, books are there, and Chang ‘an is there. "Three Wan Li in Chang ‘an" is a poem we wrote to the sages, and it is also a spiritual inheritance, "Xie Junwei said.

"Chinese confidant"

As the pioneering work of "New Culture Series" of light-chasing animation, Three Wan Li in Chang ‘an aims to capture shining figures and classic works widely respected in the history of China as creative objects and show the beauty of traditional culture in the form of animation.

The first thing that came to mind was the "Tang Dynasty". "The Tang Dynasty is a self-confident and tolerant dynasty, and Tang poetry is integrated into the blood of everyone. When it comes to Tang poetry, Li Bai will naturally blurt it out," Xie Junwei said.

Everyone knows Li Bai. He is a "Poet Fairy" and "Brewmaster", and he is also a "fallen immortal" who is pure and refined, but these auras also invisibly widen the distance between him and the audience.

The director thought of looking for an "ordinary person" to stare at Li Bai. In this way, another hero — — Gao Shi, a frontier poet, came into being.

"In history, Gao Shi and Li Bai were good friends, and he himself was legendary. Before the age of 50, it was difficult all the way, and it was not until the Anshi Rebellion that he finally achieved great success. It is easier for the audience to bring in his friendship with Li Bai from the perspective of ordinary people. "

Li Bai and Gao Shi, one is a free and wild "fallen immortal" and wrote "oh, how can I gravely bow and scrape to men of high rank and men of high office, who never will suffer being shown an honest-hearted face"; A down-to-earth "worldly person" is determined to "go straight to Chang ‘an and knock on the Tianzi Gate".

The sharp contrast between their personalities and acting styles has become the main source of conflicts in movies and dramas, but behind their different life choices, they all reveal their unremitting pursuit of poetry and ideals.

The two directors interpret their friendship like this: "Li Bai and Gao Shi admire and appreciate each other. When they first met, Gao Shi said that I had never seen such a talented person, such a naive and romantic person, and he admired Li Bai; For Li Bai, after middle-aged sumo wrestling, he said to Gao Shi: The silver saddle shines on a white horse, and it is like a meteor. This poem was written by me according to your appearance twenty years ago, and he is also expressing his appreciation for Gao Shi. "

"Their personalities are so different, but they can be together and become bosom friends. This is the romance of Chinese bosom friends that we want to embody."

One of the externalized forms of this "romance" is the three sumo fights between Gao Shi and Li Bai. Director Zou Jing told us, "The social atmosphere in the Tang Dynasty was very martial, and sumo was a popular form of sports at that time. They have three sumo wrestlers in their lives, from the youthful vigor to the vicissitudes of middle age. The body may have declined but the spirit is still there. We want to create a spiritual transmission that spans time. "

At the scene of the road show, an audience asked the director what kind of feelings besides friendship existed between Li Bai and Gao Shi in the film. The director responded: "In fact, there is no need to define what kind of emotion it is. Li Bai and Gao Shi are very important people to each other, and this state is what we want to express."

"Chang ‘an Three Wan Li"

From the splendid Chang ‘an on the top of the mountain, the beautiful Yangzhou with Erming Moon is Yangzhou, to the Yellow Crane Tower on the first floor of the world, the wonders of the Three Gorges with water and sky, and then to the magnificent scenery of Liangyuan, Tongguan, Songzhou and Jibei. …No wonder some people say that Three Wan Li in Chang ‘an is a vivid Tourism Map of Datang.

In order to create a grand scene of the Tang Dynasty thousands of years ago, the master chose the creative mode of combining data archaeology with field collection. On the one hand, I visited Shaanxi History Museum to observe the sand table map of Chang ‘an City, and referred to a large number of books and ancient paintings to reproduce the prosperous Chang ‘an in the prosperous Tang Dynasty.

On the other hand, they also personally went to Tongguan and Songzhou to collect the wind. Zou Jing recalled, "When we were in Tongguan, we stood on the wall and looked out, and we really understood why Tongguan was easy to defend and difficult to attack; We went to Songzhou and saw its walls and mountains linked together, then we understood the so-called natural barrier of the ancients. Many things have to be visited in person to understand the particularity of its geographical environment. "

Not only that, "Chang ‘an Three Wan Li" is not relaxed in the details of modeling, etiquette and props.According to the director, the crew also specially invited a etiquette guide to help the main creator reproduce all kinds of etiquette among the literati in the Tang Dynasty, such as the representative ceremony of crossing hands, not bumping glasses when touching glasses, the sense of ritual when Li Bai buried Wu Guide, and all kinds of details of "moving, sitting, lying and walking" are well documented.

"We want to present the real Tang Dynasty in detail, not only aesthetically, but also strive to make the audience return to Tang Dynasty at a glance," Xie Junwei said.

In order to restore the style of the Tang Dynasty in an all-round way, the figures in the film also refer to the proportions and shapes of figures in Tang terracotta warriors, murals and ancient paintings, forming a "tang style shape" with a majestic upper body because of its martial arts.

Specific to the two protagonists, Gao Shi has 22 versions, ranging from 8 to 60 years old, and Li Bai also has 15 versions, from youth to old age.

"Li Bai’s middle-aged state is actually the face that we are most familiar with. The inspiration comes from the illustrations next to Tang poetry in primary schools. We first determined that middle-aged Li Bai would use this shape, while Li Bai in his later years wore a plain clothes, like a youth, and returned to the true state."

In addition to the two protagonists, another highlight of the film is Du Fu, a lovely childhood, which is in sharp contrast with the gloomy and sad image of "Poet Saint" in the public impression.

The director said that this familiar and unfamiliar feeling is exactly what they are pursuing. "Is Du Fu a state of compassion from birth?" He was also a naughty and lovely child when he was a child. After he experienced setbacks and experiences, he finally became Du Fu now. This is what we want to express. We want to present these poets and these events to everyone in a more three-dimensional and flesh-and-blood way. "

Childhood du fu

In the director’s view, "Three Wan Li in Chang ‘an" tells the story of Gao Shi and Li Bai’s deep love for each other across time, and it is also a touching chapter in which the stars of the Tang Dynasty rise and fall with the times and realize their life ambitions under the magnificent background of the times.

In a limited time, the master also made famous historical figures such as Wang Wei, He Zhizhang, Zhang Xu, Cui Zongzhi, Wang Changling, Cen Can, Li Yong, Cenfuzi, Dan Qiusheng, Li Guinian, Ge Shuhan, Guo Ziyi, Princess Yuzhen appear in turn, and constructed a vivid picture of all beings in the Tang Dynasty.

"These sages in the movies made their own choices in the face of life setbacks and difficult pressures, which ultimately affected the direction of life. We will encounter the same difficulties they encountered in those years today, and I hope their choices will give the audience strength, which is the core theme of this film, "Zou Jing said.

There are a total of 48 Tang poems in the film, and how to visualize the artistic conception of Tang poems has become a big challenge for the master.

They finally chose Yellow Crane Tower, Jiang Jin Jiu and Yan Ge Xing for presentation, and Jiang Jin Jiu is undoubtedly the most difficult.

Director Zou Jing revealed: "The production cycle of the whole project is three years, and the production time span of" Into the Wine "is close to two years, and one shot has been done for half a year. This poem is particularly rich in emotion, interwoven with Li Bai’s frustration and ambition, grief and heroism, so we decided to present the world in poetry with a surreal expression. "

"Every link of this play is very difficult, from storyboard, design, animation performance, special effects and even dubbing, it is very challenging. It can be said that all our animation imagination and what we have learned are put into this poem."

To reproduce the classics in a visual way, so that poetry can resonate with contemporary audiences across the Millennium, it should also be in harmony with Gao Shi’s finishing line: "Poetry is there, books are there, and Chang ‘an is there."

"This is the origin of our creation, and the spirit of the poets has been handed down into poems." Chang ‘an Three Wan Li "is a work of spiritual inheritance and a poem for the sages."

　　The netizen who wrote "Tianjin Climbing Raiders" took a selfie on the top floor of a building. His behavior was accused of being too dangerous, and the lawyer thought it might be suspected of endangering public order.

　　Recently, some netizens published a "Raiders of Climbing Buildings in Tianjin", which described in detail how to take scenic photos on the rooftops of several high-rise buildings in Tianjin. Once released, the Raiders caused controversy, and some netizens thought that it was too dangerous to enter the roof of unopened high-rise buildings mentioned in the Raiders. Some lawyers said in an interview that shooting on an unopened rooftop may be punished for allegedly endangering public order, which will not only pose a safety risk to themselves but also to others. At the same time, the lawyer reminded that if there is a safety accident, the management or property owner of the building may also be held accountable for management negligence.

　　Netizens wrote "Tianjin Climbing Raiders" on the Internet.

　　Recently, a netizen posted a "Raiders of Climbing Buildings in Tianjin" on Weibo. In the Raiders, the netizen said that he had climbed to the rooftops of high-rise buildings in Tianjin many times to shoot. In the photos posted by the netizen, someone was sitting on the edge of the rooftops of high-rise buildings, which was very dangerous. The strategy of climbing stairs is widely circulated on the Internet.

　　The "Tianjin Climbing Raiders" published by this netizen includes 10 high-rise office buildings or residential quarters in Tianjin, such as Jinzhigu Building and Junlin Building. The raiders include the location of setting up cameras on the rooftop, how to detour upstairs, how to enter the locked rooftop, and how to avoid security suspicion.

　　Some netizens found that the rooftops in some photos lack protective measures and belong to areas that are not open to the outside world. Therefore, it is not only a security risk but also a suspicion of breaking the law to enter the rooftops in this way. Some people are worried that going in and out of the building at will affect the work and life of people in the building.

　　Photographer: I haven’t thought about it if it is illegal.

　　On the 26th, the reporter of Beiqing Daily contacted Mr. Ma, the author of "Tianjin Building Climbing Strategy". He admitted to the reporter of Beiqing Daily that this strategy was made by him, and he had personally climbed all the buildings mentioned in the article. He said that a few years ago, he climbed a building with a senior who loved photography by chance, and he has since enjoyed climbing the building to shoot landscape photography.

　　After accumulating more than one year’s experience in climbing stairs, Mr. Ma summed up his works and experiences and posted them on the Internet. He claimed that the original intention of climbing the stairs was to let more people enjoy the beautiful scenery of Tianjin.

　　In response to questions from netizens, Mr. Ma said that at the beginning of the raiders, he reminded everyone to pay attention to safety and not to do dangerous actions. "I don’t go to dangerous places, such as climbing over the guardrail of Tiantai. I’m not so dead. I will be careful not to influence others when shooting. If people think I have influenced them, I will leave. But to be honest, I really haven’t thought about whether it is illegal. "

　　However, Mr. Ma’s strategy still met with some netizens’ doubts. In a strategy, Mr. Ma said that in order to enter the rooftop, he broke a lock leading to the roof, and then "I heard that the lock on the roof was welded". Some netizens believe that this practice has destroyed other people’s property, and there are security risks.

　　Claiming to have been in a dangerous situation

　　Despite this, Mr. Ma admitted that he had encountered dangerous situations in the process of boarding the rooftop.

　　He mentioned that when he climbed the roof of Chifeng Bridge Community Building, he needed to climb a ladder 3 meters high to go to the roof. "After I went up, I found that the ladder was not strong. When I stood in the middle of the ladder, I hesitated. Is it better to go up or go down?" I was a little weak at the time, but I thought I had come here, so I’d better go up and shoot. "

　　In addition, Mr. Ma told the reporter of Beiqing Daily that sometimes there is a strong wind on the rooftop, and he will always stand in the fence and dare not turn it out.

　　He recalled that at the earliest time, he went to the rooftop of King’s Landing Building to shoot. At that time, many people besides him also filmed on the rooftop. With the increase of people, the security guards will not let people go to the rooftop, and the building has installed a monitor on the rooftop. "If you want to take photos in King’s Landing Building, you can only book a hotel room under the rooftop, so you can still take photos of the corresponding landscape and there is no security risk."

　　For some photos that look dangerous in the Raiders, Mr. Ma said that those "photos that seem to make people’s legs soft" were not taken at risk. "In fact, the place where I am standing is not dangerous, and there is a fence in that position, but if I tilt the camera slightly, I can’t see the guardrail." He said that sometimes when there is a guardrail in the photo, he will PS the guardrail, "it becomes the effect in the photo."

　　Lawyer: Behavior that disturbs public order will be punished.

　　Han Xiao, a lawyer of Beijing Kangda Law Firm, told the reporter of Beiqing Daily that according to Chinese laws, if the act of shooting on the rooftop like Mr. Ma causes the consequences of disturbing public order and endangering public safety, it can be characterized as illegal and punished accordingly.

　　"There is no protective measures to climb to the rooftop to shoot, and the probability of danger is very high. Once an accident is caused, not only is there no guarantee for your own life safety, but there is also a great chance to endanger public safety. If serious consequences occur, they can even be detained. "

　　He reminded the photographer that shooting on the rooftop should be approved by the owner or manager of the building. If the building is damaged during shooting, the owner of the building has the right to ask the photographer for compensation.

　　If the climber has the behavior of breaking the door, it should be analyzed according to the degree of property loss. If the loss is large, he can be punished by administrative detention. If the loss exceeds 5,000 yuan, he may be suspected of intentionally damaging public and private property and will be investigated for criminal responsibility.

　　Han Xiao said that according to the Tort Liability Law, managers of hotels, shopping malls, banks, stations, entertainment places and other public places or organizers of mass activities should bear tort liability if they fail to fulfill their security obligations and cause damage to others.

　　Therefore, once the photographer has an accident when shooting on the rooftop, if it can be proved that the manager or property owner of the building has failed to fulfill his security obligations and there is management negligence, he will bear part of the civil liability caused by it.

BYD’s fifth-generation DM technology is "digging" out for fuel consumption.

technical background

Motor advantage

strong

The instantaneous output peak torque at low speed is large. If the engine is used for high torque output, its related technologies are basically monopolized by relevant manufacturers in Europe and America.

fast

The motor torque adjustment is 20 times faster than that of the engine. At present, there is no gearbox to adjust the conversion torque in the electric drive on the market, and the electric control cycle is only 5ms, while the intake, compression, work, exhaust and power output of the engine take 100ms in one cycle.

So it’s more direct

accurate

Compared with the oil truck, the resolver identification accuracy is 300 times higher, the former is 0.02 degrees, while the latter is 7.5 degrees. Such applications as the ESP function of the chassis system are basically mastered by Bosch.

(B) the advantages of the engine

Steady-state high-efficiency kinetic energy output, that is, the steady-state high-efficiency generator engine and the series mode function in the middle and low speed state, and the steady-state high-efficiency driving in the high-speed cruise stage, while if the speed changes frequently in the middle speed driving, the excess engine energy is recovered by means of motor parallel speed increase or motor charging.

The core of the optimal architecture selection of BYD’s power system (pay attention to the non-planetary gear architecture) lies in how to give full play to the electric driving power and how to dispatch the engine power, as shown in the following figure.

(3) Comparison between PHEV and HEV

The fuel consumption is low. After all, for DM, the engine is only an aid. In most cases, it is only used to generate electricity for extended range when commuting. With high-power motor driving, the driving experience will be much better. At the same time, it has a large battery support and has the function of external discharge.

The fifth generation DM technology

Three major architectures

Power architecture based on electricity

Plug-in special high-efficiency engine: the engine with the highest mass production thermal efficiency of 46.06% in the world, and the improvement measures include

The world’s highest ultra-high compression ratio is 16. For the problems such as knocking and thermal management that may be caused by this, measures have been taken.

In order to improve the oxygen content of intake air, a high tumble port is adopted, and the combustion efficiency is improved by oxygen-enriched environment.

The EGR system is newly designed, and the middle urging is changed to the front urging.

The shape and inner wall of the combustion chamber are specially optimized.

Intelligent EFI system (mentioned again later)

The cylinder block and the cylinder head are cooled separately, and the energy consumption of the engine cooling and cooling system itself is reduced.

An intelligent variable lubrication system is designed to reduce engine friction loss.

Optimization of engine intelligent start-stop strategy

In the process of conventional engine starting, the instantaneous current will be very large when starting with a small battery of 12V, so the engine speed can only be raised in a certain period during the process of pulling the engine; Using high-voltage power electric drive to start can reduce the current and pull up the engine speed more quickly, and also avoid the resonance chattering problem that may be caused by the motor pulling up the engine;

At the same time, in the process of quickly pulling up the engine speed, the rapid power output of the engine itself is ensured by excessive fuel injection.

The energy loss can be reduced by 16%.

Extreme control optimization of system efficiency

By using the power battery as the energy reservoir, the engine can maintain a more efficient working condition as much as possible, and make full use of the driving advantage mainly based on electricity.

EHS electric hybrid system

electrical machinery

Segmented magnetic steel & ultra-thin silicon steel sheet to reduce magnetic loss and eddy current loss.

The double mechanical pumps in the motor cooling system are upgraded to the double pump coupling-rotor oil throwing technology, that is, one mechanical pump and one electronic pump, and the latter is started and stopped as needed, so the cooling process is more detailed.

clutch

The transmission efficiency between the motor and the wheel end is improved, which is transmitted by two gears and bearings. The previous generation adopted cone bearing, which has high strength but low efficiency, so it was upgraded to ball+column bearing and high efficiency clutch.

The motor speed is 16,000 rpm (132 kW, 316N.m) in the previous generation, and now it is 18,000 rpm (120 kW, 210 N.m); And the volume, power and torque of the motor are all reduced, but the power is not weakened, and the output of the wheel end is only amplified by a larger gear ratio.

The comprehensive working condition efficiency is improved by 5%

Insert-mix special blade battery

The energy density increased by 15.9%, the discharge rate increased by 33%, and the energy recovery increased by 20.3%. Because the battery capacity is large, the weight of the vehicle is bound to increase, which puts forward higher requirements for energy consumption. Therefore, part of the solution is made by improving the energy recovery rate, making a small motor mention and weight.

Charging and discharging experience upgrade

The slow charging power is upgraded from 3.3kw to 6.6kw.

DC fast charge for 21 minutes.

The external discharge is increased from 3.3kw to 6kw to meet the needs of more outdoor vehicles.

12V Ferrous lithium phosphate starter battery.

Status decline, especially in the process of vehicle starting, which was originally powered by 12V battery and transferred to electric drive.

The weight dropped from 12kg to 2.2kg

The small battery will have the same life cycle as the whole vehicle, so there is no need to change it frequently, and there is no need for the small battery to be dead.

When the small battery loses power, the power battery will charge it; If the power of the large battery is not enough, it will start the engine stomach power battery to replenish power. So don’t be surprised to see the car parked there and no one suddenly started in the future.

The small battery has its own independent BMS, which is used to communicate with the power battery.

Full temperature range vehicle

Active air intake grille, under the condition of low temperature, when the engine needs to be warmed up, the air intake grille is closed, and the water temperature rises faster; In hot weather, open the air intake grille to exchange heat and improve the heat dissipation in the front cabin; Close the air intake grille at high speed to reduce wind resistance.

Battery thermal management system

The battery direct cooling technology is adopted, and the battery is directly blown by the cooling capacity of air conditioner.

The temperature equalization technology is improved, and the shape of the cold plate flow channel is optimized to make the effective area better. The active temperature equalization technology is used, and the control valve is arranged at the cooling port, which is actively opened when the temperature needs to be lowered, so that the temperature equalization is improved by 45%, the battery activity can be kept in the optimal temperature area better and faster, and the energy consumption is saved by 34%.

The application of pulse self-heating technology, that is, heating through high-frequency charging and discharging between batteries, improves the heating speed by 60%.

Cabin thermal management, through intelligent switch internal and external circulation, actively control the compressor, blower and internal and external circulation switch according to the temperature, light and position (such as tunnel environment) inside and outside the vehicle.

Seven-in-one power domain control, through the improvement of chip and communication speed, strengthens the integration of all components, improves the power density of electric drive system, and improves 18.3%.

Wind resistance of the whole vehicle is 0.26Cd.

Low wind resistance rim

Low drag caliper

The integrated flat chassis, which has been extensively evaluated on the Internet, is no longer an oil-to-electricity structure. The layout and technology of the whole car chassis have been improved a lot, and of course the comfort has also been significantly improved.

Electronic and electrical architecture

Combined with different scenes and different parts of vehicles (such as oil, machinery, electricity, liquid, heat, etc.), the intelligent switching of vehicle modes, intelligent power distribution and intelligent voltage adjustment are carried out through historical massive data and AI technology.

The AI energy consumption mode of the vehicle system will intelligently adjust the power consumption or oil consumption strategy according to the congestion situation and road conditions during the navigation of Gaode map.

Recently, Ms. Bian from Shanghai bought 10 Jin of peanuts online for 6.81 yuan in the live broadcast room. After receiving it, she found only 10. Ms. Bian said in an interview with @ Litchi News that at the time of live broadcast, the merchant said that 10 Jin of peanuts were guaranteed not to be bad. Now the store has been cancelled, and the delivery phone can’t get through. I can’t contact the merchant myself and feel cheated.
