Is the air quality inside the subway better than outside? Survey: Not necessarily, generally worse than outdoor.

[Survey] The public pays little attention to the air in the subway.

The subway is becoming a mode of transportation for more and more people. According to the statistics of Beijing Municipal Transportation Commission, in 2017, the proportion of green travel in downtown Beijing reached 72%, and the average daily passenger traffic of rail transit network reached 10.3 million. According to the statistics of Beijing Metro Company, on March 27th this year alone, the daily passenger traffic of 16 operating lines under the jurisdiction of Beijing Metro Company reached 10,008,800 passengers.

What followed was the increase in people’s time on the subway. According to incomplete statistics, Beijing subway passengers spend an average of two hours in the subway every day. Therefore, how the air quality in the subway becomes very important and what adverse effects it may have should be paid enough attention by the public.

Volunteers conducted a questionnaire survey in the subway.

However, the reporter’s random survey found that the public paid little attention to this. Not long ago, Beijing issued the first blue warning of dust this year, and the air quality in the whole city reached the level of heavy pollution. At Guangqumennei Station of Metro Line 7, many people naturally took off their masks after entering the subway station. The reporter interviewed a girl in her twenties at random. She told reporters: "Wearing a mask for a long time feels very oppressive, and there is no way for the air outside to be heavily polluted. When you enter the subway station, you don’t have to wear it. " She believes that there is air conditioning in the subway, which will filter pollutants in the air.

The reporter also asked some subway passengers. Most people think that the air in the subway is better than that outside. Is this really the case? The reporter interviewed Zhao Ang, the director of Panshi Institute of Environment and Energy and the main person in charge of the subway air pollution research project.

[Truth] There are obvious differences between different subway lines.

Panshi Institute of Environment and Energy recently released the information map of "Investigation on the Characteristics of Air PM2.5 Exposure and Coping Behavior of Beijing Subway Commuters". In 2017, they successively conducted a series of surveys and assessments on the differences in air pollution exposure levels of commuters in Beijing subway and the corresponding health impacts.

"We conducted a questionnaire survey on 618 people in the Beijing subway." Zhao Ang said that 76% of the respondents thought the outdoor air quality was worse than that in the subway. But the actual monitoring situation is the opposite. During the investigation in the subway, the daily average concentration of PM2.5 was 154 μ g/m3 in winter heating season and 127 μ g/m3 in non-heating season, while the daily average in outdoor Beijing was 103 μ g/m3 and 69 μ g/m3, respectively.

Through monitoring, experts also found that not only the air quality in the subway is generally worse than that outside, but also the differences between the lines are obvious. "By horizontally comparing the average concentration of PM2.5 in different subway lines, we found that the air quality of Line 13 was the best and Line 8 was the worst within half a year of project monitoring." Zhao Ang said.

According to statistical analysis, Metro Line 2 and Line 13 have the lowest concentration of PM2.5, and Line 8 has the highest concentration of PM2.5. "The monitoring results of this time are similar to those of the subway air monitoring in our’ measuring the air in the corner’ project in 2015." Zhao Ang said that it seems that this situation has not changed.

"If we compare the outdoor air quality of Line 13 and Line 8, we can find that the PM2.5 concentration level of Line 13 is close to the outdoor during the monitoring period of up to 6 months, especially in the non-heating season. This may be related to the long outdoor part of the line, good ventilation and relatively slow speed. "

Zhao Ang told reporters that the concentration of PM2.5 in Line 8 is always higher than that outside, whether in heating season or non-heating season. Similarly, Line 6, with poor air quality, also shows a greater difference from outdoor air quality.

[Response] Over 7 adults are willing to pay for improving the air.

"The actual situation of subway air quality is inconsistent with the cognition of many citizens, which also requires the public to strengthen this awareness." Zhao Ang said that the relationship between knowledge and action is an important field of decision-making science and behavioral science research. "When we analyze the survey data, we see that the respondents understand the inconsistency between air pollution and coping behavior, and also understand that there are many factors that affect the relationship between knowledge and action."

Zhao Ang said that although most people think that air pollution has a noticeable impact on people’s lives, the proportion of people who wear masks when taking the subway is not high. "When taking the subway, the proportion of people who never wear masks is as high as 36%, and only 7% of people always wear masks."

He believes that this inconsistency in cognition and behavior is largely related to people’s ignorance of the reality that the air quality in the subway is worse than that outside. On the other hand, it is also related to people’s judgment on the pollution protection effect of wearing masks. "More than two-thirds of the respondents believe that masks have no obvious protective effect."

In addition, the research group also found that there is a significant positive correlation between income level and education level and willingness to pay for air purifiers. In this regard, Zhao Ang explained that the higher the education level or income level, the higher the willingness to pay for air purifiers. There is no correlation between these two factors and the willingness to pay for purchasing anti-haze masks.

According to the survey report, among the 618 respondents, 88.2%(545 people) think that increasing the consumption of renewable energy (such as wind power and solar power) is helpful to alleviate the air pollution in Beijing. Among them, 478 people are willing to increase their monthly electricity bill in order to improve the air quality in Beijing.

[Tips] Wearing a mask is the best protection.

"The best way is to wear a mask in the subway." Zhao Ang said, "Because it takes a long time to control air pollution, personally, the most effective means of protection is probably to wear masks often, especially when taking the subway."

Zhao Ang told reporters that cardiovascular disease is one of the main health risks caused by air pollution exposure. Fudan University once asked 30 young college students to do relevant experiments to evaluate the potential cardiovascular health benefits brought by wearing a mask (model: 3M-8210V) that can block PM2.5 fine particles.

The experimental results show that wearing a mask in a short time can improve Heart Rate Variability (HRV) and reduce ambulatory blood pressure and circulating biomarkers, indicating that wearing a mask can alleviate the harm of air pollution to cardiovascular diseases. On the contrary, if you don’t wear a mask, the inhaled particles will increase, which will lead to the decrease of HRV parameters, which is potentially harmful to cardiovascular diseases.

"Of course, this experimental study also has some limitations." Zhao Ang said, for example, due to the small sample size, this study is exploratory in nature; Because the personal exposure to PM2.5 has not been detected, it is inevitable that errors will occur when measuring exposure; The monitoring device is not calibrated by gravity measurement, and some indoor factors, such as human activities, will affect the exposure concentration of individual PM2.5.

"Although there are some limitations, this randomized controlled crossover experiment still provides preliminary evidence that wearing masks can be used as an effective practical tool to protect individual cardiovascular health, thus reducing the harm of air pollution."

CNNIC released the 46th Statistical Report on Internet Development in China.

On September 29th, China Internet Network Information Center (CNNIC) released the 46th Statistical Report on Internet Development in China (hereinafter referred to as the Report). The Report focuses on five aspects: Internet infrastructure, the scale and structure of netizens, the development of Internet applications, the development of Internet government affairs and Internet security, and strives to comprehensively reflect the development of China’s Internet in the first half of 2020 through multi-angle and all-round data display.

Internet inspires great power and helps to win a great victory in the fight against epidemic diseases.

According to the Report, as of June 2020, the number of netizens in China reached 940 million, an increase of 36.25 million compared with March 2020, and the Internet penetration rate reached 67.0%, an increase of 2.5 percentage points compared with March 2020. Wu Tienan, secretary of the Party Committee and deputy director of CNNIC, pointed out that during the epidemic, China’s Internet industry showed great vitality and resilience, which not only played a key role in accurately and effectively preventing and controlling the epidemic, but also made remarkable progress in digital infrastructure, digital economy, digital benefiting the people and digital governance, and became an important force for China to meet new challenges and build a new economy.

Zhang Xiao, deputy director of CNNIC, interpreted the report and summarized the highlights of Internet development in China in the first half of 2020 from eight aspects:

First, the "net" sinks strength, and the "new format" helps to fight the epidemic and stabilize the overall situation.In the first half of the year, online education, online medical care, telecommuting and other application services played a great role in maintaining the normal operation of social economy and stabilizing the basic needs of people’s livelihood. As of June 2020, the number of online education users reached 381 million, accounting for 40.5% of the total netizens; The number of online medical users reached 276 million, accounting for 29.4% of the total netizens; The number of telecommuting users reached 199 million, accounting for 21.2% of the total netizens.

The second is "net" Luo technology, and "new infrastructure" injects vitality expansion.In the first half of the year, the central government intensively deployed to speed up the progress of "new infrastructure" and made positive progress in many important areas: by the end of June 2020, the number of 5G terminal connections had exceeded 66 million, and three basic telecommunications companies had opened more than 400,000 5G base stations. More than 500 industrial Internet platforms with distinctive features and diverse capabilities have been cultivated in the field of industrial Internet. By July 2020, the number of users with assigned IPv6 addresses in China reached 1.442 billion, and the number of active users with IPv6 reached 362 million. The top 100 commercial websites and applications have all supported IPv6 access.

Third, the "network" promotes development, and the "new economy" expands domestic demand to help transformation.By June 2020, the number of users of e-commerce live broadcast, short video and online shopping in China had all increased by more than 5% compared with that in March, and the number of users of e-commerce live broadcast had reached 309 million, an increase of 44.3 million compared with that in March 2020, with a scale growth rate of 16.7%, making it the fastest-growing personal Internet application in the first half of the year, providing positive help for promoting the transformation of traditional industries and promoting the upward movement of agricultural products. The number of online retail users reached 749 million, accounting for 79.7% of the total netizens. The market remained the first in the world for seven consecutive years, which provided important support for the formation of a new development pattern.

Fourth, the "net" has temperature, and the "new Huimin" Lipui helps to get rid of poverty.As of June 2020, the number of netizens in China has reached 940 million, equivalent to one-fifth of the global netizens. The Internet penetration rate is 67.0%, which is about 5 percentage points higher than the global average. The digital gap between urban and rural areas has narrowed significantly. The difference in Internet penetration rate between urban and rural areas is 24.1%, which has been reduced to less than 30% for the first time since 2017. As an important means of poverty alleviation, online poverty alleviation has been increasingly understood and participated by netizens.

Fifth, the "net" comes to culture, and the "new communication" storytelling creates a new style.By June 2020, the number of users of online video (including short video) in China reached 888 million, accounting for 94.5% of the total netizens, among which short video has become a new choice for news reporting and a new standard for e-commerce platforms. The number of users of online news is 725 million, accounting for 77.1% of the total netizens. With the help of social networking, short videos and other platforms, online news can improve communication efficiency through visualization and help anti-epidemic propaganda and reporting.

Sixth, the "net" knows the world, and the "new tool" sees the world from a distance.By June 2020, the number of online payment users in China had reached 805 million, an increase of 4.8% compared with March 2020, accounting for 85.7% of the total netizens. The mobile payment market ranked first in the world for three consecutive years, which played an important role in benefiting the people during the epidemic and expanded more application scenarios of "+payment"; Instant messaging has become one of the fastest growing applications during the epidemic, with a user scale of 931 million, an increase of 34.66 million compared with March 2020.

Seventh, the "net" fills the demand, and the "new service" ensures the capacity to supplement the supply.Affected by the epidemic, online channels have provided a new development window for the service industry. Digital services such as online take-out, online education, online car rental, online medical care and so on are booming, with the number of users reaching 409 million, 381 million, 340 million and 276 million respectively, accounting for 43.5%, 40.5%, 36.2% and 29.4% of the total netizens respectively, which not only meets the needs of netizens, but also provides assistance for the digital development of the service industry.

Eighth, "net" talks about governance, and "new governance" pushes legislation for innovation.By June 2020, the number of online government service users in China reached 773 million, accounting for 82.2% of the total netizens. In the first half of the year, the government governance system was continuously improved and its governance capacity was continuously improved.Civil Code of People’s Republic of China (PRC)People’s Republic of China (PRC) Data Security Law (Draft)Gradually promote digital governance with laws to follow; A multi-collaborative governance system around government, platform and society is accelerating; Online government service is becoming more and more mature, and the construction of national government service platform has achieved remarkable results.

Promote "internet plus"Government affairs service,Prevention and control of epidemic situation, resumption of work and production

Wang Yimin, director of the E-government Research Center of the Party School of the Central Committee of the Communist Party of China (National School of Administration) and deputy director of the National E-government Expert Committee, believes that the data in the Report fully reflects the continuous improvement of China’s Internet+government services and the continuous improvement of the digital governance system in the first half of the year. First, the construction of the national government service platform has achieved remarkable results. By June 2020, the registered users of the national government service platform reached 126 million, with a total of 1.002 billion visitors and a total of 5.891 billion views. A five-level online service system of "covering urban and rural areas, linking up and down, and clear hierarchy" has taken shape. Second, grid governance has brought forth new ideas. Urban and rural communities in many provinces and cities have actively carried out epidemic prevention work through digital tools such as community WeChat groups and small programs, which has become a major innovation in grassroots governance. Third, "Internet+government service" has strongly promoted the resumption of work and production after the epidemic. The national government service platform has successively launched "service columns for small and micro enterprises and individual industrial and commercial households" and 15 service topics such as epidemic prevention and control, resumption of work and production, and employment services. At the same time, it has built an "epidemic prevention health information code", which has gathered and supported 623 million pieces of "health code" data shared by all localities and served 600 million people, which has become an important innovation in this big data support for epidemic prevention and control.

The safety experience of netizens in China has been continuously improved, and the network security environment has been further improved.

Huang Qing, vice chairman of internet society of china, said that in the first half of 2020, China’s network security environment showed a trend of continuous improvement under the continuous crackdown on various network security issues by the National Internet Information Office, the Ministry of Industry and Information Technology and other relevant departments. First, at the policy-making level, People’s Republic of China (PRC) Civil Code, People’s Republic of China (PRC) Data Security Law (Draft) and other relevant laws and regulations have been promulgated one after another, which has promoted the continuous improvement of China’s network security legal system. Second, in terms of infrastructure, China has vigorously promoted the deployment of national top-level domain name resolution nodes, and successively introduced F, I, L, J and K mirror servers to promote the security of network infrastructure. Third, in terms of user safety, the data in the Report shows that Internet users are experiencing increasingly improved network security problems, and the proportion of Internet users who have not encountered any network security problems has kept increasing for five consecutive years. Fourth, in terms of industrial development, the development of China’s network security industry has entered the "fast lane". The existing network security products and services have extended from the basic network security field to different application scenarios such as cloud services, big data, Internet of Things, industrial control, and 5G, achieving comprehensive coverage of basic equipment, basic technologies, security systems, and security services.

Under the background of "new infrastructure", the new format of digital economy helps to enhance the "resilience" of China economy.

Lv Benfu, vice chairman of the National Innovation and Development Strategy Research Association and director of the Network Economy and Knowledge Management Research Center of the University of Chinese Academy of Sciences, believes that under the impact of the COVID-19 epidemic in the first half of the year, China’s economy was forced to stretch its "ligament" and faced new challenges in supply chain, enterprise management and business activities. The new format and mode of digital economy and the rapid development of digital technology have provided important support for enhancing the toughness of China’s economic "ligament" and promoting the formation of new economic growth points. First, digital technologies such as 5G and industrial Internet provide the underlying foundation for the digital economy. With the help of digital technology, large-scale matching algorithm and high-speed network are transmitted to the cloud, which makes information transmission faster and energy dissipation less, and promotes the digital economy to become a "low entropy economy". Second, digital consumption, such as online shopping, has provided new impetus for promoting economic internal circulation. In the first half of the year, the scale of online retail sales has exceeded a quarter of the total retail sales of social consumer goods, and its supporting role for consumption has been further enhanced. According to the data in the Report, new e-commerce models such as fresh e-commerce, agricultural products e-commerce, cross-border e-commerce and second-hand e-commerce have also maintained rapid development, with the user scale reaching 257 million, 248 million, 138 million and 61.43 million respectively, which has played an active role in promoting the upward movement of agricultural products, driving consumption back and promoting the development of idle economy. Third, digital services represented by telecommuting are forming a new service format. As can be found from the Report,The number of users of online education, online medical care and telecommuting reached 381 million, 276 million and 199 million respectively, making it an Internet application with great development potential, and constantly enhancing the economic resilience while promoting innovation in the service industry.

networkPoverty alleviation has achieved remarkable results.To benchmarkrural revitalizationbuildLong-term mechanism

Wang Xiangdong, former director of the Information Research Center of China Academy of Social Sciences, believes that it is very rare for this Report to record China’s remarkable achievements in network poverty alleviation with multi-dimensional data. First, rural areas have achieved network coverage, and the gap between urban and rural areas has narrowed significantly. According to the data in the Report, the Internet penetration rate in rural areas was 52.3% in the first half of the year, which was 6.1 percentage points higher than that in March 2020, and the difference between urban and rural areas was reduced by 6.3 percentage points. Second, the era of "the same network and the same speed" between rural and urban areas is coming. The proportion of fiber-optic access to poor villages in China has increased from less than 70% in 2017 to 98%, and the proportion of broadband access to poor villages in deep poverty areas has increased from 25% to 98%. Third, the effectiveness of online poverty alleviation has been recognized by the majority of netizens. By the end of June 2020, the proportion of netizens who recognized the Internet in "helping the poor", "helping the sales of agricultural products through e-commerce" and "providing more jobs and medical education opportunities for the poor" had increased compared with that in March 2020. Wang Xiangdong also said that in order to consolidate and expand the achievements of poverty alleviation, online poverty alleviation needs to establish a long-term mechanism, and it needs to realize the transformation from helping poverty alleviation within a limited period to helping stable poverty alleviation, from helping absolute poverty to helping relative poverty, from "blood transfusion" to "hematopoiesis" and from helping poverty alleviation to revitalizing industries through online consumption.

46th Statistical Report on Internet Development in China (full text)

Audi, Porsche gave up Le Mans, and Mercedes gave up DTM, all for it.

The traditional racing bible is being revised, and the international giants’ attention to the event is quietly changing, all because of the big environment.

Self-abandonment of racing giants

There are not many racing giants in the world today. Here are a few that will surely convince the public.

Participated in 1999 and won 13 championships so far. Among them, from the second year of the competition (2000), it won three consecutive championships. In 2004, another five consecutive championships began. In 2010, it was another five consecutive championships.

Has decided to leave the once glorious Le Mans battlefield.

This achievement is quite amazing. By the way, if you mention some details of these ten years, your worship of you may be further deepened. In 2003, EXP Speed 8 won the championship, but it was actually a car in a coat, so strictly speaking, it should have been nine consecutive championships since 2000-this is terrible!

And left, there was only one LMP1 group, I don’t know what it was like.

In addition, R15 TDI Plus, which won the championship in 2010, finished the race with a distance of 5410.713km, creating the longest race distance in the history of the 24-hour Le Mans race, and this record has been maintained to this day.

Now, I have to say goodbye to such a brilliant record, and I have said that I will no longer participate in the Le Mans LMP1 group competition.

This name, it seems, is the same as drawing an equal sign. It is the brand that has won the Le Mans Competition the most times in history, winning the championship for 19 times.

The 917K in 1970 opened the era of Le Mans Competition.

In 2015, he returned to Le Mans and ended the dynasty with 919 Hybrid racing car, and won the championship for three consecutive years. Just after winning this year’s Le Mans championship in June this year, he suddenly announced his withdrawal from the Le Mans competition in LMP1 group.

This year, 919 Hybrid won the championship again in Le Mans Competition, and then suddenly announced the launch of LMP1 group events.

Overnight, he quit one after another, leaving those who had never won the championship alone in the wind.

In recent years, it has dominated the grand prix, making the former giants follow behind them, including Williams, Williams and so on.

Mercedes-has become the ruler today.

However, it is not just announced that it will withdraw, but another influential event in Europe-DTM (German Touring Car Masters). As the most famous touring car race in Germany and even in Europe, DTM represents the highest level of touring car races. In DTM, it is an old-fashioned powerhouse and has been fighting here for more than 20 years.

Quit DTM, stay with two companies, and the future of this event suddenly becomes a mystery.

In 1988, he began to participate in DTM events, won the championship for the first time in 1992, and is now one of the three major DTM teams. After leaving, there will be only two DTM companies, which is also quite unfavorable to the development of DTM. Uncle’s move is not as good as merging into Japan’s Super GT in the future, and the joint venture between the two parties is more exciting.

They all chose formula e.

These three racing giants have left their best fields and where have they gone?

The answer is actually the same: Formula E, FIA electric equation, that is, domain.

A few days ago, when I confirmed my withdrawal from DTM, I confirmed that I would move to Formula E in the future. It is expected that the competition time will start from the 2019/2020 season. In fact, the accumulated experience in the field in recent years will be well used in Formula E events, and focusing on two equations at the same time will not be too complicated for event management.

In fact, I have participated in Formula E race a long time ago, just in the form of cooperation with Abt Schaeffler team. However, it was recently revealed that it will officially enter in the form of an independent team in the 2017/2018 season.

Earlier, it was reported that after leaving Le Mans, it is planned to March in the 2019 season. If so, then the strategic direction will be the same, and the two most important and top-level Formula One competitions on the planet will be launched.

It has also been confirmed that it will participate in the Formula E competition, and the time is 2019/2020 season. This is a decision based on the 2025 strategy. In the future, we will develop civil electric power with Mission E as the blueprint, so as to kick off the model. Obviously, participating in Formula E competition will bring more benefits to the company’s career development.

Why is Formula E so popular?

What else can it be because of? Because of environmental protection.

Germany has announced that it will stop manufacturing and selling internal combustion engines in 2030, which is the most obvious hint for all manufacturers: it’s time to do it well. Not only Germany, but also Denmark, Britain and Sweden have similar policies coming to the fore. Of course, these mainstream European car companies are not so passive, and they are already leading the world in research and development. However, with the promotion of the government and the pace of development, we can go further, such as participating in Formula E.

From the point of view of racing circle, Formula E is getting more and more attention because of environmental protection. Many people you are familiar with have actually participated in this project, such as,,,, and so on. They either set up factories to participate in the competition or provide key technologies.

In a word, Formula E is the most correct event at present, and it will hardly be opposed by any party, because in this era-environmental protection is the greatest.

More Q version of Binguo? The brand-new Wuling Hongguang MINI EV real vehicle exposure, adding a four-door version.

"What the people need, Wuling will build", which is the spiritual characteristic of Wuling, and is also the recognition and expectation of consumers for Wuling.

Under the influence of consumption upgrading and market demand change, the A00-class electric vehicle market is no longer the fiery trend of previous years. Even Hongguang MINI EV, which has been in the leading position for a long time, now its sales volume has plummeted. In order to enhance the competitiveness and expand the market boundary, the official launched a brand-new fourth-generation Hongguang MINI EV. The new car not only has a brand-new appearance, but also adds a more practical four-door version. Recently, some netizens photographed the real car map of the brand-new Hongguang MINI EV, and it seems that the official listing date will not be too far away.

The new fourth-generation Hongguang MINI EV is available in three-door and four-door versions. The real car exposed this time is a four-door version, which is longer than the current body size and the overall shape is more rounded and lovely. Specifically, the front part of the new car adopts a design similar to Wuling Binguo, with a rounded nose and a slightly concave closed grille. The headlights on the left and right sides are enlarged in size, and the oval shape has changed into a bubble-like rounded shape. The annular LED strip and blackened headlights are used in the lamp cavity, which is more smart and fashionable.

The charging interface is still set in the center of the front of the car. The side of the car body has a rounded shape and soft lines. It is equipped with traditional door handles, and macaroon color matching with brand-new two-color wheels enhances the fashionable and lovely attributes. In the rear part, the shape of the taillights echoes the headlights, the rear compartment cover becomes larger, and the whole tailgate is smoother, which is unified with the overall style.

In terms of size, the length, width and height of the new Hongguang MINI EV are 3256/1510/1578mm and the wheelbase is 2190 mm. The three-door version and the four-door version are the same size. In contrast, the length, width and height of the current Hongguang MINI EV are 3064/1493/1614mm, and the wheelbase is 2010 mm. The length and width of the new car are improved, the wheelbase is increased by 180mm, and the height is reduced by 36 mm..

The interior part basically continues the design of the current model, equipped with double large-size floating LCD screens, with double-width multi-function steering wheel and knob shift. On this basis, the air conditioning outlet under the central control panel is decorated with oval chrome, the air outlets at both ends of the center console are changed to round, and the door panel lining has also been adjusted in color matching.

According to the declaration information disclosed by the Ministry of Industry and Information Technology, the new car comes standard with a single motor drive, with a maximum power of 30kW, which is consistent with the 2024 Wuling Hongguang MINIEV Youth Edition and Advanced Edition. Matching it is a 16.2kWh lithium iron phosphate battery pack, with a CLTC cruising range of 205km and a maximum speed of 100 km/h.

When the overall performance of the whole mini-electric vehicle market declined, the sales volume of Hongguang MINI EV was dragged down. Although the subsequent introduction of Wuling Binguo filled the sales vacancy to a certain extent, the two models were not of the same level after all, and people expected to see a cheaper and more practical mini-car, rather than a small car above the mini-car. Now the brand-new Hongguang MINI EV has entered the market with a new attitude, and we will wait and see whether it can return to the peak.

Let Mobile Photography Say Farewell to "Digital Taste" —— The Story Behind Xiaomi × Leica Image Quality Experience Improvement Project

Let Mobile Photography Say Goodbye to "Digital Taste"

—— The story behind Xiaomi × Leica Image Quality Experience Improvement Project

□ Our reporter Peng Xie

"Is it correct to make the night scene as bright as the day? At night, is there at least a’ night sense’? " This is a question raised by Lei Jun, founder, chairman and CEO of Xiaomi Company in Weibo. In fact, it is not difficult to brighten the night scene for the current mobile image photography equipment, but it is not easy to restore the "night feeling" seen by the eyes.

In the eyes of the industry, "lighting up the night scene" is the inevitable result of some mobile phone manufacturers’ over-reliance on computational photography and post-optimization, with the aim of lowering the threshold for taking a "good" photo. These so-called "good" photos are brighter than the colors seen by the eyes, brighter than the real light, and the details are still clear when magnified several times. But in the eyes of photographers and enthusiasts, there is an unreal "digital taste".

Say goodbye to the taste of digital and return to the real world of light and shadow, which is what users expect from the image experience. In July, 2022, Xiaomi Company announced the strategic cooperation with Leica, the leading brand in the global imaging field, to realize the original Leica image experience on the mobile phone, form Xiaomi’s unique image quality style, and redefine "good photos". Behind it, it is Xiaomi people’s diligent pursuit of image quality style and the ultimate exploration of digitizing style.

Call up the user’s favorite "Leica flavor"

For more than 100 years, Leica cameras have formed a unique "Leica flavor" by virtue of exquisite optical engineering design and powerful manufacturing technology. After a year-long in-depth communication with Leica, Xiaomi explored the key elements of "Leica flavor"-three-dimensional tone, telepresence color and soft and realistic details.

But this is far from enough. The real "Leica taste" is not counted by Leica, nor by Xiaomi, but by users.

The project team spent a lot of time and energy to screen out a group of professional photographers and enthusiasts who are familiar with Leica and agree with Xiaomi, conduct in-depth interviews, and define the Leica style in the eyes of users through the comparison and selection of a large number of proofs. The process of deep communication with users is like building a city of light and shadow, brick by brick, interlocking and striving for perfection, just to make professional photography simpler and images more realistic.

In this process, the project team made a new discovery-on the basis of ensuring authenticity and naturalness, many users also like the samples with fuller and sharper colors compared with the original Leica samples. Therefore, the project team decided to develop two styles of "Leica Classic" and "Leica Vivid" simultaneously. The former perfectly reproduces the imaging style of Leica camera, abandons the effect of forcibly brightening the traditional mobile phone image, makes the darkness dark, and the color is full of "German flavor"; On the basis of maintaining accurate restraint, the latter moderately brightens and adjusts the saturation of the picture, showing bright and sharp tones and vivid and full colors.

After the dual-style route was clear, the project team and Leica reached a consensus, and the raw images of Leica M series cameras were used as input, and intelligent processing was carried out through machine learning algorithm. Dynamic brightening technology, deepAWB technology, extreme image quality technology and efficient computing technology were innovatively used to create a material library for hundreds of subdivided scenes such as portraits, blue sky, sunset, green plants and flowers, and all the materials were disassembled according to the dimensions of exposure, contrast, color and noise.

The quality of images is not only a standard, but also a promise to users. In the technical adjustment, the project team chose the most difficult and least tricky way-brand-new pipeline and parameter design, and distinguished "Leica Classic" and "Leica Vivid" from the bottom parameters. It is several orders of magnitude more difficult to do this than to adjust the surface parameters, and it also brings huge workload to the later adaptation, but only in this way can "Leica Classic" and "Leica Vivid" truly achieve their own wonderful.

Taking the birthday cake as an example, Leica Classic adopts neutral white balance to make the picture and color more calm and objective. "Leica Vivid" uses white balance parameters that are more suitable for human eyes and emotions to enhance the sense of atmosphere and make the picture warmer, "equivalent to adding a warm filter to the picture".

Let the public take good photos at will.

Optical problems must be solved in an optical way. In the cooperation between Xiaomi and Leica, the two sides have a consensus that excessive use of computational photography due to insufficient optical quality will cause irreversible damage to the picture, which is tantamount to quenching thirst by drinking poison. This means that Xiaomi is going to change or even subvert the aesthetic habits that the public has long cultivated by "computational photography" and "post-optimization". Photographer Huang Cao questioned: "It takes a lot of courage and determination. Will there really be mobile phone manufacturers who dare to do this?"

In June, 2022, Xiaomi invited 25 professional photographers, including Huangcao, to attend a closed-door communication meeting, and took out the unreleased 12s Ultra engineering machine for trial use. The purpose was to let everyone judge whether this mobile phone was "Leica" or not.

After taking a few photos with Xiaomi 12s Ultra engineering machine, the weeds feel that the texture is completely different from that taken with a mobile phone. Li Yue, the product manager of Xiaomi Camera Department, was surprised by a car photo taken by a photographer. "It’s better than I expected!" He said.

At this closed meeting, Xiaomi collected some opinions and suggestions from photographers, including the problem of "white balance adjustment of multi-focus switching" put forward by weeds-when shooting the sea with a short-focus lens of a mobile phone and a small boat in the sea with a telephoto lens, the color of the sea surface will be deviated due to different focal lengths. For ordinary users, this is a subtle difference that needs careful comparison to find, but for photographers, it is an unavoidable problem.

Li Yue and his colleagues believe that these 25 photographers are heavy users of Leica, and the problems they found may not be the most sensitive and concerned by ordinary users, but they are very critical to the image quality and Leica style, and have a "high priority". Although it is difficult to change, they are willing to face the difficulties. "Our goal is to let the public take good photos and get the best photography experience, so the first thing we have to do is to tell everyone what a good photo is." They said.

Subsequently, according to the photographer’s opinion, the project team set up a special group such as "multi-camera consistency" to focus on tackling key problems, from camera adaptation to chip debugging, and make all-round improvement. When Xiaomi 12s Ultra was officially released, Huangcao was pleasantly surprised to find that Xiaomi had solved almost all the problems mentioned at the press conference. "In addition to the rapid improvement, Xiaomi’s emphasis on photographers’ ideas is also very touching." He said.

Thanks to the efforts of the project team, Xiaomi 13 Ultra, the latest flagship of humanities imaging specialty released in 2023, was officially defined as a "fantastic historical work" by Leica, and the praise rate of the self-operated flagship store in JD.COM was over 99%. It is Xiaomi people’s persistent pursuit of "quality" to take users as the center and take user satisfaction as the goal, so that users can take pictures of the most beautiful scenery at will. Saying goodbye to "digital taste" and returning to "optical taste" is Xiaomi’s pursuit of moving images and the definition of "good photos", which has been verified in Xiaomi 13 Ultra.

The cooperation was praised by the German team

Xiaomi joined hands with Leica, which promoted the deep cooperation and mutual appreciation of engineers from two different countries. It is precisely because Xiaomi and Leica attach equal importance to the user’s experience and actual needs, pay more attention to quality from the user’s point of view, and pay more attention to aesthetics and humanistic feelings, so the cooperation between the two sides will be so efficient and successful.

In the cooperation, the dedication and seriousness of Leica engineers left a deep impression on Xiaomi engineers.

At the beginning of the cooperation, Xiaomi sent a Xiaomi 11 Ultra mobile phone to Florian, a Leica camera expert, and happened to meet Florian on vacation. Unexpectedly, in the first week after he came back from vacation, he sent a 128-page image quality evaluation report PPT-the result of his vacation with his mobile phone.

Before each meeting with Xiaomi, Leica engineers will communicate relevant information, reports or target maps internally. After the meeting, they will hold another round of resumption and planning meeting. Minutes of each meeting are very detailed and can be issued immediately after the meeting; Reports and materials used in the meeting will also be sent out before 24: 00 on time.

Every time the Xiaomi project team puts forward a product functional requirement, the Leica team will "ask three questions"-do users really need it? What benefits does this have for users? How to improve the effect of taking pictures? "Treating every question of users with caution and echoing everything is also a tacit understanding that we complement each other with the Leica team." An engineer of the Xiaomi team said.

In cooperation, collision is inevitable. According to Li Yue’s recollection, the project has to complete Leica certification for more than 200 sub-items including basic scenes and special scenes. For the Xiaomi team who is good at "grabbing time", so many projects should have "priority" to ensure that the most important problems are solved in the shortest time. But in the eyes of German engineers, every project is equally important and should go hand in hand.

In order to convince German engineers, Li Yue took advantage of the convenience of living in the same community with them, and took a walk with Leica engineer Florian at the weekend, explaining why he should give priority while walking. Walking for more than two hours, German engineers told Li Yue a message from all dimensions-NO (No), which made Li Yue unable to refute.

To Li Yue’s surprise, as soon as he started work on Monday, the German team produced a report of more than 200 pages, analyzed the importance of each certification project, and determined the problems and objectives to be solved in each project. The two sides discussed the report from morning till late at night, and finally determined the "priority" of each project. Strict management and strict requirements in research and development are the consensus of the two teams. Only by being strict and sincere can we be worthy of making friends with users.

It is said that people with the same gas field will attract each other, and the engineer culture respected by Xiaomi has made the German team find a full sense of belonging. The dedication of Xiaomi’s team won the respect and recognition of German engineers, and also changed their working methods imperceptibly.

For example, in Xiaomi Science and Technology Park, the two sides often have to discuss for most of the meeting, which often delays eating. As a result, the Leica team quickly developed the habit of bringing their own energy bars and chocolates to the meeting. For another example, at the beginning of the cooperation, Leica HR agreed that they should not work more than 7 hours a day, but after arriving in Xiaomi, they unconsciously adapted to Xiaomi’s working mode and even blurred the "concept" of vacation, and they would also do shooting tests and reports on weekends. "No one asked them to do this. I think this is a kind of like-mindedness." Li Yue said.

Youth is fleeting, but style lasts forever.

Leica is far more beautiful than it looks at first sight. It is durable, and you can look at it again-this is Leica’s confidence.

Clearly know and insist on what to do and what not to do, without losing focus and being disturbed by noise-this is Xiaomi’s certainty.

Simpler and purer, Xiaomi’s understanding of a good photo has also become Xiaomi’s unique image quality style through excellent lens and precise interactive solidification, making future moving images more "millet flavor". This cooperation between Xiaomi and Leica has been well received, which is a model of the perfect combination of innovation and quality of Xiaomi.
