Does the panda’s "dark circles" turn white? Professor Sichuan Agricultural University reveals the truth.

  Cctv news(Reporter He Chuan) Recently, the "dark circles" of some giant pandas in chengdu research base of giant panda turned white, which attracted the attention of the national panda powder.

  "Dark circles" is the "signboard" of the national treasure giant panda. What causes it to turn white? Can the "dark circles" of giant pandas change back? On January 25th, Yang Guangyou, a professor at the College of Animal Medicine of Sichuan Agricultural University, was interviewed by a reporter and gave detailed answers to the questions that netizens were most concerned about. It is understood that Yang Guangyou is one of the members who participated in the "rescue" of the giant panda "dark circles".

  The "hair loss" of some giant pandas is actually caused by sampling.

  At the end of 2017, careful "Panda Powder" found the recent photos and live videos of "white eyes" of online celebrity giant pandas Qiyi, Qifu, Xiaoya and Yongyong in chengdu research base of giant panda on social media. From a photo published by Sichuan media, it can be clearly seen that the "dark circles" of this giant panda have obviously turned white and their hair has fallen off.

  Chengdu research base of giant panda staff said in an interview with the media that Sichuan’s humid and humid environment is more conducive to bacterial reproduction than other dry areas, and some giant pandas are sensitive in constitution, so mite infection is very easy to occur. The infection caused by the suspected mites is not explosive, but sporadic and not contagious. Currently living in chengdu research base of giant panda, there are no more than 10 giant pandas with eye depilation.

  Yang Guangyou told the reporter: "We have recently paid attention to three giant pandas with serious clinical symptoms ‘ Yongyong ’ 、‘ Qiyi ’ And ‘ Xiaoya ’ Anesthesia was performed, and skin samples around the eyes were scraped and sent to the parasitology laboratory of Sichuan Agricultural University for PCR detection of demodex, and the test results were negative. In order to further these ‘ Mite eye ’ The individual was diagnosed, and the base invited me to have a bedside examination. At present, the test is being repeated. Once the PCR is positive, the base will use the screened effective drugs for treatment. "

  Yang Guangyou said: "According to my observation, the condition of the giant panda in the base is mild, because only the lesions appear around the eyes, and the spirit and appetite are normal, and there is no malnutrition or weight loss, but the giant panda is ‘ National treasure ’ , so the condition was artificially amplified. According to the symptoms and signs, at present, it can only be said that mite infection is suspected. These giant pandas were scraped off due to sampling, and some netizens thought that the hair loss was aggravated, which was actually caused by sampling. "

  "Saving" the giant panda "Black Eyesocket" is in action.

  How do these giant pandas suspected of being infected with mites recover? How long will it take to change back to "dark circles"? These two issues are the most concerned by netizens.

  Yang Guangyou said that if it is diagnosed as mite infection, you don’t have to worry too much. It is just a very common skin disease, and domestic pets and humans have different degrees of infection. "acariasis is one of the common ectoparasitic diseases of giant pandas. The main pathogens are scabies, itchy mites and demodex. Its clinical symptoms are itching, scabbing, depilation and skin thickening. Ivermectin and Serratin have achieved good therapeutic effects on scabies and itch mites. The appearance of the giant panda at the base as claimed by netizens ‘ Mite eye ’ Veterinarians began to investigate the etiology and etiology more than a year ago, focusing on the detection of demodex, fungi and vitamins and trace elements, but the cause has not been identified. " Yang Guangyou said.

  Yang Guangyou said that apart from parasitic infection, there are many reasons that lead to animal body depilation, such as lack of vitamins and trace elements. At present, experts are also looking for possible causes from these aspects, and finding the cause can be targeted for treatment.

  Finally, Yang Guangyou said, "If it is diagnosed as mite infection, the base has screened out Isoxazoline (trade name BRAVECTOR, Afoxolaner, etc.) and MilbemycinOxime, and made safety tests. As long as the right medicine is given, the hair will grow back quickly after treatment. ‘ Dark circles ’ Come back, netizens don’t have to worry too much. "

Build the whole ecology of people, cars and homes! Xiaomi 澎湃 OS technology white paper released

[TechWeb] On December 7, 2023, Xiaomi held an OS experience communication meeting with the theme of "Fantasy". Jin Fan, vice president of the mobile phone department of Xiaomi Group, said that once Xiaomi 澎湃 OS was released, it caused a heated discussion and received wide acclaim from the media and users. At the communication meeting, Xiaomi 澎湃 OS R&D team introduced the aesthetic design and experience details of the new system to users in detail, and released a white paper on Xiaomi 澎湃 OS technology to the public, aiming to stimulate more creativity and cooperation by sharing these technological achievements and insights, promote the progress of the whole industry, and jointly build the future of "all people, cars and homes".

Reconfiguration of the bottom layer can fully release the performance of the equipment.

In 13 years, from 100 users to 1.175 billion cumulative users worldwide; From the absence of hardware to the ecological layout of more than 200 categories today-the era of the Internet of Everything, the complexity and huge number of operating system branches involved in equipment, and the barriers to ecological connection caused by different systems and protocols may not be as deep as Xiaomi’s experience. Thus, Xiaomi 澎湃 OS came into being. The project was launched in 2017, aiming at unifying all ecological devices through a set of integrated system framework, achieving the goals of optimal device performance, unified experience among devices and open connection.

The underlying core system of Xiaomi 澎湃 OS is a fusion of Linux and self-developed Xiaomi Vela, with excellent heterogeneous compatibility and precise and powerful system resource management capabilities, so that each device can exert its best performance. The bottom layer of Xiaomi 澎湃 OS supports more than 200 processor platforms and more than 20 common file systems, covering hundreds of equipment categories and thousands of SKUs. It can be flexibly configured, operated and deployed according to hardware-the compatible device RAM is as small as 64KB and as large as 24GB. Based on the principle that different hardware only configures necessary resources, and with the file deduplication and compression of the underlying IO technology stack, Xiaomi’s surging OS is naturally lightweight: on the mobile phone side, the system firmware occupation of Xiaomi’s surging OS can be as low as 8.75GB, which is far lower than that of competing products.

Scheduling is the soul of the system. The core system of Xiaomi 澎湃 OS has finer scheduling ability. By dynamically adjusting thread priority and dynamically evaluating task cycle, it can accurately command hardware and tasks in various complex and high-pressure scenarios, bringing the ultimate performance and power consumption. Using a mobile phone equipped with Xiaomi 澎湃 OS to run large-scale games has a more stable frame rate and lower power consumption performance compared with native Android or other deeply customized OS. On lightweight devices with limited computing power, Xiaomi 澎湃 OS has more obvious performance scheduling advantages: it supports splitting a task into multiple computing units for collaborative computing, which can maximize hardware performance. Not only that, Xiaomi 澎湃 OS has also reconstructed many technical modules such as file system, memory management, network system and graphics subsystem, which can effectively exert the hardware capabilities of various devices with great differences and bring the ultimate single device performance.

Cross-end Zhilian, let the connection enter the next era

Giving full play to single-ended performance is only the foundation. In the era of Internet of Everything, it is necessary to connect devices efficiently, but also to integrate the connected devices into a whole. To this end, Xiaomi 澎湃 OS has developed a cross-end interconnection framework, Xiaomi HyperConnect, on top of the core system to realize the real-time networking of ecological devices. Through the brand-new converged device center, users can see all the devices in the surrounding network and their current status, and realize active and fast device control. No matter at home, on the road or in the company, users can see that the devices connected around them move with the current scene and state.

Xiaomi 澎湃 OS makes all connected devices into a whole, and software and services can choose the most suitable hardware among all devices according to users’ needs. When using tablet and notebook for video conference, you can flexibly switch to the camera angle of the mobile phone; On the way to driving, you can even call the car camera on the mobile phone; When working outside, the tablet can call the mobile phone communication module to surf the Internet. Not only that, the applications currently used by users, the contents in the clipboard and focus notifications can also flow freely among connected devices according to the needs of users.

Active intelligence, so that devices can understand people’s minds and serve people.

Device interconnection and capability integration are only prerequisites. In order to achieve the ultimate goal of the Internet of Everything era and make devices actively serve people, strong intelligent lighting is needed. Xiaomi 澎湃 OS is equipped with a forward-looking AI subsystem, which supports the most advanced AI technology to land in the system and gives equipment intelligence. This time, the AI subsystem will support two AI highlight applications to land in Xiaomi 澎湃 OS.

Xiaomi HyperMind is the thinking center of Xiaomi’s whole equipment, which brings the device interconnection into the era of "active intelligence" for the first time in the industry, so that devices can truly understand people’s minds and take the initiative to serve people. It turns 820 million devices in more than 200 categories of Xiaomi Ecology into tentacles to perceive the world. It comprehensively uses the four perceptual abilities of environment, vision, hearing and behavior to learn the habits and preferences of different users, and actively implements them after acquisition, adjusting the devices around users to the state of users’ habits. For example, every time the user opens the smart door lock, the lamp in the living room will be turned on. After Xiaomi HyperMind learns this habit and obtains the user’s permission, the lamp can be automatically turned on every time the user opens the door. Xiaomi HyperMind truly solves the problems of complicated logic and high learning cost of traditional device interconnection, so that users can enjoy the convenience brought by device interconnection without understanding complex operation logic and trigger mechanism.

The big model is a hot technology in the field of AI today. Xiaomi 澎湃 OS fully embraces the big model of AI, enabling it to fully apply the system. Xiaoai input assistant allows users to quickly call the text creation ability of the big model of AI in the input method interface, such as generating speeches and summarizing articles. The well-received real-time subtitle function has been upgraded, which can transfer the real-time subtitles of video conferences to notes and intelligently refine the minutes of meetings; After the system photo album is combined with the AI big model, the AI picture searching ability is added. Users can find the desired pictures only by using daily communication sentences without accurate description, and also support the generation of AI photos based on the existing portrait photos in the photo album. The "Xiaomi Creation" App on the tablet adds an AI brush, which can transform the user’s graffiti into beautiful paintings. Not only the system application, but also the three-party application can release more potential after accessing the AI subsystem. In WPS, users can ask questions about the documents they take at hand and quickly understand the meaning; You can also use a sentence instruction to quickly generate PPT.

The extensive application of AI big model needs leading and efficient technical architecture as support. The AI subsystem of Xiaomi 澎湃 OS supports the deployment of large models to the device NPU, which improves the operating efficiency and reduces the power consumption of the device. Based on this, Xiaomi 澎湃 OS was able to support the running of Xiaomi self-developed model on the mobile phone side for the first time. Taking the large image model as an example, compared with the traditional CPU scheme, Xiaomi’s self-developed NPU scheme reduces the model size by 75%, the memory occupation by 75%, and the drawing time from 100 seconds to 5 seconds. The end-side image ability will soon be applied to the "Wen Sheng Tu" function of Xiao AI’s big model version and the "AI Tu Extension" function of album editing. Xiaomi will continue to embrace cutting-edge AI technology and bring users a truly intelligent life.

Global security, guarding every usage scenario of users.

Privacy security is the cornerstone of all experiences, and it is also the experience track for Xiaomi to continue to exert its strength. Xiaomi 澎湃 OS reconstructs the security and privacy architecture for the Internet age. Xiaomi’s self-developed TEE is the underlying foundation of the security subsystem, which is an isolated security operating system running on isolated hardware, specially used to process sensitive information to ensure the security of information. It covers the security functions of many system applications, such as face recognition, privacy password, screen lock password and so on. Not only core devices such as mobile phones, but also AIoT devices are supported. Xiaomi’s self-developed TEE is the first TEEOS in China to obtain the highest certification level EAL5+ certificate from China Network Security Review Technology and Certification Center (CCRC), which is also the highest security level of TEEOS at present.

Xiaomi 澎湃 OS security subsystem not only provides a unified security guarantee for each device, but also designs an interconnected security module for each device. Interconnection needs to ensure that every device in the network is trustworthy. Xiaomi 澎湃 OS allows devices to check each other through an interconnection security module based on TEE, and data transmission between devices is also encrypted end-to-end through TEE, thus ultimately ensuring the security of the whole network.

Xiaomi firmly believes that users have the right to know and control their privacy, and the privacy flare function pioneered by Xiaomi has also become the network access standard of the Ministry of Industry and Information Technology. Facing the era of the Internet of Everything, Xiaomi 澎湃 OS has upgraded its rights management ability to the ecological level, and provided functions such as rights management, sensitive internet reminders, sensitive internet records, etc., making the rights acquisition in the internet scene completely transparent to users and highly controllable by users.

The underlying reconstruction, cross-end intelligent, active intelligence, global security and open ecology, Xiaomi 澎湃 OS is undoubtedly the turning point of Xiaomi’s leap. The release of Xiaomi 澎湃 OS is a key step after the upgrade of Xiaomi’s technology strategy, marking the gradual improvement of its map of "people, cars and homes are all ecological". I believe that the launch of Xiaomi 澎湃 OS will definitely bring an unprecedented new experience to Xiaomi eco-users.

There are more intelligent configurations in the BMW iX car.

The interior space of BMW iX adopts Shy Tech stealth technology design concept, with smaller air outlet, larger curved surface screen, and 50% fewer physical buttons than current BMW models. At the same time, BMW iX also adopts hexagonal steering wheel design.

▲ BMW iX interior

There are two display screens in the car, the instrument screen size is 12.3 inches, and the central entertainment screen is 14.9 inches. The pixels per inch of these two screens is above 200ppi. According to the viewing distance in the car, the driver can hardly distinguish the pixels on the screen.

▲ BMW iX central control screen

The eighth generation iDrive system of BMW is built in the car. This system is based on Linux. The UI design is more modern and the operation is more intuitive. At the same time, it is more convenient for the owner to interact with the car by adding a voice assistant that can talk in natural language. For China users, services provided by Tencent and Alibaba will also be added to the system.

In addition, BMW iX also has a brand-new intelligent personal assistant built in. The driver can give the intelligent personal assistant a name he likes and use it as a wake-up word. BMW’s intelligent personal assistant has the ability of natural dialogue and context understanding, and can learn the driving habits of users. Can make better suggestions when performing multiple tasks at the same time.

Through multiple microphones, BMW Intelligent Personal Assistant can also pick up the sound in different areas in the car to distinguish the objects of conversation, and can communicate and operate according to the situation considering the situation of the vehicle and its surrounding environment.

In addition to the built-in BMW’s eighth generation iDrive system, BMW iX can also use mobile phone mapping systems such as Apple CarPlay and Android Auto in the car.

In 2020, 5G technology has been widely popularized in the field of consumer electronics, and many self-owned brand models are also equipped with 5G modules.

Imported/joint venture car companies seem to be relatively conservative about 5G technology, but BMW is still at the forefront. The BMW iX model will be equipped with 5G communication module, which will bring more improvements to people’s travel experience in the fields of entertainment, information, autonomous driving and road safety in the future.

5G will also promote the further application of cloud technology. BMW has transferred a lot of computing power and functions to the BMW cloud, and processed a lot of data and complex tasks through the BMW cloud computing center.

The BMW i4 model released in advance includes two versions, i4 eDrive40 and i4 M50.

▲ Comparison of important parameters of typical luxury brand pure electric coupe

In terms of appearance, BMW i4 is a coupe with short front and rear suspension, thin side beams, frameless doors and streamlined roof.

The front of the car adopts narrow headlights and BMW’s classic "kidney" shape, which has become one of the appearance standards of BMW I series. The i4 M50 can also be equipped with optional M kit, which includes more flamboyant aerodynamic components, larger rims, etc. to make the vehicle look more combative.

▲ BMW i4

As for the power system, i4 adopts BMW’s latest fifth-generation eDrive electric drive system, which integrates the motor, inverter and gearbox, and has the advantages of simple layout and light weight, with an energy density of 2.14kW/kg.

▲ BMW i4 electric drive system

It is worth pointing out that the motor used in the electric drive system is an electrically excited synchronous motor, which has the advantage of maintaining constant torque output in a fairly wide speed range.

The efficient and compact electric drive system gives BMW the opportunity to give excellent power performance to the i4 model. Among them, i4 eDrive40 adopts the rear wheel drive mode, and the peak power of the electric drive system on the rear axle is 250kW (about 340 HP) and the peak torque is 430N?m. It takes only 5.7s to propel this vehicle with a curb weight of 2125kg to accelerate from 0 to 100 km/h.

▲ BMW i4

The i4 M50 adopts four-wheel drive mode, and the front and rear electric drive systems work together. The peak power of the electric four-wheel drive system is 400kW (about 544 HP), and the peak torque reaches an astonishing 795N?m. With such abundant power, it takes only 3.9 seconds for this vehicle with a curb weight of 2290kg to complete the 0~100km/h acceleration.

In terms of batteries, BMW said that the high-voltage lithium battery used in i4 has a higher technical content than the battery of i3 model, so the energy density has increased by about 20%. At present, both i4 eDrive40 and i4 M50 models are equipped with a lithium battery with a capacity of 83.9kWh (usable capacity is 80.7kWh).

▲ BMW i4 battery pack

In order to keep the battery in its best working condition as much as possible, BMW designed an efficient temperature control system for i4. This system is integrated with the battery pack, which can be heated when it is cold and cooled when it is hot, so that the temperature of each position of the battery pack is as stable and consistent as possible.

With the help of the temperature control system, the battery of i4 can not only support the powerful power output of the electric drive system, but also give the i4 model considerable cruising range.

Under the working condition of WLTP, the energy consumption of i4 eDrive40 is 16~20kWh/100km, and its comprehensive cruising range is 590km;. The energy consumption of i4 M50 is 19~24kWh/100km, and its comprehensive cruising range is 510km.

▲ Charging BMW i4

On this basis, BMW also designed a "Combined Charging Unit" for the i4 model, which gave the i4 the ability to charge quickly.

For example, when using fast-filling piles, i4 supports charging power up to 200kW. Assuming that only 10% of the battery energy is available when the vehicle starts charging, people can get about 164km(i4 eDrive40) or 140km(i4 M50) cruising range in just 10 minutes at this power.

If people are not in such a hurry, it’s ok to wait for a while, because the charging speed of i4 in fast charging mode is very fast, and the charging time from 10% to 80% is only 31 minutes (the same is true for i4 eDrive40 and i4 M50).

In terms of intelligent cockpit, BMW i4 adopts a dual screen design with a 12.3-inch display and a 14.9-inch central control screen, which, like BMW iX, can provide quite a lot of information and a quite shocking sensory experience. Moreover, the double screen adopts the design of curved screen and inclines to the driver’s seat at a certain angle, which is the implementation of BMW’s consistent concept of "driver first".

▲ BMW i4 interior

On this basis, i4 is also equipped with a head-up display system to further enhance the visual experience of drivers and passengers. For example, during driving, the display screen will display information such as map, current position, route planning, etc., while the head-up display system will display tips such as vehicle speed, steering tips, lane change recommendations, etc., so that drivers can see intuitive and concise route guidance information without taking their eyes off the road.

On the center console, the i4 model did not keep too many physical buttons, but integrated the functions corresponding to the buttons into the touch screen. The car also adopts BMW’s eighth generation iDrive system, and its interface and functions are basically the same as BMW iX.

At the same time, i4′ s car system integrates Apple CarPlay and Android Auto mapping system, which has a high tolerance for smart devices such as mobile phones and tablets, and can truly realize end-to-end ecological integration. Users can also customize the car system of i4 through the My BMW App application. In the future, i4′ s car system will also support OTA upgrade. With the blessing of 5G communication technology, OTA upgrade will be very fast.

▲ BMW i4 seat

In terms of intelligent driving, the i4 model has SAE L2-class automatic driving capability, with up to about 40 driving assistance functions. Among them, the functions of forward collision warning, speed limit warning and lane departure warning are standard in the whole department, and the optional functions include adaptive cruise with automatic (adjustable) speed limit assistance, road monitoring, steering and lane keeping assistance, traffic light recognition (only available in Germany) and so on.

It is worth pointing out that the adaptive cruise function of i4 can not only adjust the vehicle speed according to the speed of the preceding vehicle and the set distance, but also adjust the vehicle speed according to the road speed limit. The system will call the road speed limit information provided by the navigation system to ensure that the vehicle will not exceed the speed limit, and at the same time let the vehicle drive safely in the lane through the lane departure warning/avoidance function.

The forward collision warning/avoidance function of BMW i4 has also been upgraded. BMW said that i4′ s sensing system can accurately identify vehicles in static or moving state, as well as pedestrians and cyclists. With a more efficient sensing system, i4 can better avoid collisions.

In addition, parking distance assistance and reversing camera are also standard in the whole system, and optional functions include reversing collision warning and panoramic 3D image display.

Among traditional car companies, BMW’s intelligent process can not be underestimated. In the fields of autonomous driving and intelligent cockpit, BMW already has a large number of core technologies, which is pressing for new forces to build cars step by step.

At the same time, BMW’s electrification transformation is also the fastest in the industry. As early as 2014, BMW has mass-produced two models, i3 and i8, laying the foundation for future models. Nowadays, a large wave of pure electric products are put on the market, which shows BMW’s determination in the field of intelligence and electrification.

Big data | Shanghainese dominate the Spring Festival file. Female audiences dominate the box office 100%


1905 movie network news The film market in the Year of the Dog got off to a good start, with a box office of 5.6 billion yuan, making it the strongest Spring Festival file in the history of film in the Mainland! Up to now, the total box office of six new films released in the Spring Festival of the Year of the Dog has exceeded 7.6 billion yuan.


On the first day of New Year’s Day, the mainland film market was in full swing, attracting 1.3 billion yuan in one fell swoop, which not only set a new record for last year’s Spring Festival file, but also created a single-day box office record in the global market, which shocked the world.


China audience who love movies, you are the best!


On the first day of the Lunar New Year, six new films, "Great Achievements", jointly pushed the box office of the Spring Festival to a new high of 5.699 billion yuan, a sharp increase of 76% over the same period last year; The total number of people watching movies reached 143 million, up 58% over the same period of the Year of the Rooster. The total number of screenings also exceeded the 2.3 million mark.


In which city do people love to walk into the cinema during the Spring Festival? Do you know who is the real leader who dominates the box office, men or women? Today, through a set of big data, we will reveal the unique taste of watching movies in various cities and the box office trend of six new films in the Spring Festival.


Not convinced? It turns out that the favorite movie in the country is the taste of Shanghainese Imperial Capital, which is a bit fascinating.


Most people choose to go back to their hometown for the Spring Festival, and the box office generated under such objective conditions seems to better represent the taste of watching movies in a region.


This year, Guangdong surpassed Jiangsu and became the new overlord of box office in provinces and cities during the Spring Festival. Judging from the performance of the city, we should praise the people of Shanghai. You are not mistaken, Magic Capital once again dominates this time, defending the city that loves to watch movies during the Spring Festival in China.


The Spring Festival in the Year of the Dog is a happy event for Shanghai. Two football teams in the same city remained unbeaten in the AFC Champions League — — Shanghai has two consecutive victories in Shanghai and two consecutive victories in Shanghai Shenhua. Of course, the people of Modu not only love watching football, but also watching movies. During the Spring Festival holiday, the Shanghai audience easily contributed 210 million yuan to the box office, which was 62% higher than that in the same period of the Year of the Rooster. It was easy to crush Beijing, Chongqing, Chengdu and Guangzhou again, and they properly took the top spot in the Spring Festival file of the Year of the Dog, showing their domineering. Just ask the people of the whole country, are you convinced?


But the most curious thing is, who is contributing to the box office of Journey to the West, Nineteen Generations of Ancestors and Catch the Demon 2, which are only 4.7 points, 4.9 points and 5.3 points respectively?


OMG, the greatest contributor to Nineteenth Generation of Ancestors turned out to be Beijing. Although Beijingers love to listen to the music, for movies, the taste of Imperial Capital is really a little fascinating.


Shanghainese’s favorite movies are Detective Chinatown 2 and Operation Red Sea, but Magic Capital is also the biggest ticket warehouse for Catch the Demon 2 and Journey to the West. This taste range, I can only say that the people of Modu are tolerant of movies.


Have you pierced your heart? Women are the box office leaders, and the main force of watching movies is under 30 years old.


It is said that women hold up half the sky, but on the issue of the right to speak in movies, women are the absolute leader. Even Operation Red Sea’s male-oriented movies, which are about military action, have a female audience, which is surprising.


According to the cat’s eye statistics, the proportion of female audience in Tang Tan 2, Catch the Demon 2, Operation Red Sea’s Journey to the West to the Daughter’s Country, Bears Appear and Metamorphosis, and Nineteenth Generation of Ancestors is all female, without exception.


Among them, Operation Red Sea is the film with the largest proportion of men among the six new films, but it is only 46.7%. Interestingly, the proportion of men in Operation Red Sea’s first-tier cities is actually slightly higher than that of women, but in the second, third and fourth-tier cities, women win completely.


The movies with the smallest proportion of men are "The Metamorphosis of Bears" and "Catch the Demon 2", with only 34.4% and 37.6% respectively.


Oh, male audience, please come on!


Judging from the distribution of age groups, the main force of watching movies in the Spring Festival stalls is 20-29 years old. Is it hard?


Among them, the audience of "Tang Detective 2" is the youngest, with nearly 30% of the audience coming from the age of 20-24, and the movie that is watched the least at this age is "The Metamorphosis of Bears".


The audience aged 25-29 is the most stable audience, and the proportion of this age group in the six films is between 22% and 27.5%, with little difference.


The most popular movies for older audiences are Operation Red Sea’s Nineteenth Generation of Ancestors and Catch the Demon 2, with audiences over 40 accounting for more than 10% of these three films.


Super inspirational! Operation Red Sea’s box office counter-attack narrowly beat "Tang Tan 2" as the king.


The box office trend of the six new films in this year’s Spring Festival file can be described as ups and downs and unpredictable.


On February 16th, the first day of the Lunar New Year, "Catch the Demon 2" broke 500 million yuan to win the single-day box office, taking the first place, and will be dismounted to sit on the throne of the single-day box office champion in mainland film history. At the same time, "Catch the Demon 2" also created ten records in China film history, such as pre-sale box office, single-day person-times, and the fastest break of 500 million.


Subsequently, "Catch the Demon 2" set a new record for domestic movies to break 1 billion at the fastest time (85 hours). However, the good times didn’t last long. "Catch the Demon 2" opened higher and went lower, and the box office fell all the way. Only two days later, it was completely overtaken by Chinatown Detective Case 2 on the third day of the New Year’s Eve.


In the end, "Tang Tan 2" not only became the first movie in the mainland to break 300 million yuan in a single day for four consecutive days, but also won the box office championship in the Spring Festival of the Year of the Dog.

But the most noteworthy thing is Operation Red Sea, which, despite a bad start, only earned 129 million yuan at the box office on the first day of its release, ranking fourth. However, on the second day of New Year’s Day, Operation Red Sea became the only film with a negative trend, and on the same day, it surpassed Journey to the West’s Daughter Country and rose to the third place in the single-day box office. On the fourth day of the Lunar New Year’s Day, the film counterattacked "Catch the Demon 2" and rose to the second place.


In the end, Operation Red Sea, by virtue of word-of-mouth fermentation, embarked on an inspirational road of "opening low and going high". The film not only won the third place in the Spring Festival with a box office of 1.19 billion, but also became the only one of the six new films whose box office went up all the way.


After the Spring Festival holiday, Operation Red Sea has been the top box office champion for three consecutive days, which is gratifying.


Throughout the Spring Festival of the Year of the Dog, Tang Case 2, Catch the Demon 2, Operation Red Sea, Journey to the West, The Metamorphosis of Bears, and Nineteenth Generation of Ancestors took in 1.886 billion yuan, 1.698 billion yuan, 1.19 billion yuan, 613 million yuan, 411 million yuan and 86.76 million yuan respectively during the six-day holiday.


Chinatown Detective 2, with a box office of nearly 1.9 billion yuan, successfully broke the single box office record of the Spring Festival file (1.5 billion yuan) and became the champion of the Spring Festival file in the Year of the Dog.


The movie with the highest attendance rate was won by Operation Red Sea, which won the first place with a slight advantage of 0.04%, beating Tang Detective 2. Catch the Demon 2, Bears Appear and Metamorphosis, Journey to the West, Daughter Country and Nineteenth Generation of Ancestors are ranked three to six.


Of course, after the Spring Festival holiday, it failed to stop the people from watching movies. As of press time, the box office of Tang Case 2, Catch the Demon 2, Operation Red Sea, Journey to the West’s Daughter Country, Bears’ Appearances and Metamorphosis and Nineteen Generations of Ancestors have reached 2.48 billion, 1.95 billion, 1.87 billion, 660 million, 500 million and 110 million respectively.

I cann’t accept it! There is no doubt that the young people in the town will continue to make waves during the Spring Festival and become a blessed land for domestic films.


In 2015, third-and fourth-tier cities began to rise, forming a new force that cannot be underestimated in the film market, and "small town youth" has also become the hottest new term in the film circle.


2016 was a year of rapid development in third-and fourth-tier cities. At that time, the box office of the Spring Festival in fourth-tier cities increased by as much as 131.4%. Last year, the box office of the Spring Festival in first-tier cities showed negative growth, while the box office in second-tier cities only increased by 1 million, but the growth in fourth-tier cities still exceeded 13%, reaching 145 million.


At that time, all kinds of news such as "domestic movies depend on the faces of young people in small towns" emerged one after another.


By 2018, "young people in small towns" have more right to speak, and the mainland film market not only still depends on the face of "young people in small towns", but this situation is becoming more and more prominent.


In the Spring Festival of 2018, the total box office showed a blowout trend, and the box office of cities at all levels also increased accordingly. However, in terms of growth rate, third-tier and fourth-tier cities increased by 83% and 80% respectively, and the legendary swordsman.


Judging from the box office data of the Spring Festival in the past five years from 2014 to 2018, the box office proportion of first-and second-tier cities continued to decline, in contrast to the steady and rapid growth of the box office proportion of third-and fourth-tier cities.


What is even more impressive is that the enthusiasm of young people in small towns for watching movies has been rising year after year, especially in fourth-tier cities. The number of people watching movies in the Spring Festival file has surged by 44.2 million in five years, with an exposure of 406%, beating the first, second, third and third tier cities. The number of people in first-tier cities increased the slowest, only 149%.


The upsurge of cinema construction is also sinking, and it continues to expand rapidly to the fourth and fifth tier cities. Whether it is the addition of cinemas or the number of new screens, the growth rate of fourth-and fifth-tier cities is considerable.


Most importantly, compared with first-and second-tier cities, young people in small towns are more enthusiastic about domestic films, which is an absolute blessing for domestic films.


In 2015, the box office of domestic films contributed by first-tier cities was 4.7% less than that of imported films, but the box office of domestic films contributed by fourth-and fifth-tier cities was completely superior to that of imported films, which was 2% and 4.4% higher than that of imported films respectively.


In 2017, the box office of domestic films in first-tier cities lost to imported films again, accounting for only 46.2%, while the box office of domestic films in fourth-and fifth-tier cities remained firm, reaching 61.9%.


Young people in small towns can be described as die-hard fans of domestic films.


From the box office comparison of cities at all levels in the Spring Festival of 2018, it is not difficult to see that the fourth-and fifth-tier cities are more in pursuit of "Detective Chinatown 2" and "Catch the Demon 2". It is precisely because of the contribution of young people in the town that these two films were able to win the box office crown and runner-up in the Spring Festival of the Year of the Dog.


Operation Red Sea, on the other hand, was "defeated" at the box office in the third, fourth and fifth tier cities, which led to the film’s third place in the Spring Festival file.


You know, in 2015, it won the box office of 540 million yuan in one fell swoop and became the biggest dark horse in the film market. At that time, the young people in the towns along the 345 th line jointly contributed more than 60% of the box office. However, in the Spring Festival of 2018, Operation Red Sea, a movie with the same theme, accounted for only 50.4% of the box office in the third, fourth and fifth tier cities.


The young people who win the town win the world! Facing the increasingly saturated first-and second-tier movie markets, young people in small towns have undoubtedly become a new growth point of Chinese movie box office and an important ticket warehouse of domestic movie box office, which should not be underestimated.
