A little-noticed species monitoring started, and zoologist Long Yongcheng felt that he had "no regrets in this life".

　　On November 18, 2017, in a conference room of the Forestry Department of Yunnan Province, Long Yongcheng, with gray hair, said with emotion: "All my dreams have blossomed!"

　　On the same day, the "Yunnan Golden Monkey Dynamic Monitoring Project" was announced. This project, involving 8 institutions including Yunnan University, Dali University and related nature reserves, and funded by Southwest Project Center of Alashan SEE Ecological Association, is the first synchronous dynamic monitoring of Yunnan golden monkey population in China.

　　Long Yongcheng, who has been roaming in Yunnan Golden Monkey Kingdom for 30 years, has been calling for a national investigation of Yunnan Golden Monkey. He said that with the reduction of virgin forest area, Yunnan golden monkey is facing the crisis of disappearing. As a national treasure, Yunnan golden monkey, who is also dressed in black and white, has not received the same care and favor as the giant panda. "The giant panda has conducted four national surveys, but the Yunnan golden monkey has not once."

　　In March 2017, Yang Zongliang, a representative of the National People’s Congress, submitted the "Proposal on Strengthening the Protection of Yunnan Golden Monkey" written by scientists such as Long Yongcheng to the Fifth Session of the Twelfth National People’s Congress. The Ministry of Environmental Protection replied that it is necessary to "accelerate the population monitoring and habitat restoration of Yunnan golden monkey".

　　"So far, there are less than 3,000 existing 15 groups of Yunnan golden monkeys. Few people have seen them. Many people still can’t imagine what kind of animal Yunnan golden monkey is. " Long Yongcheng said.

　　They have been missing for more than half a century.

　　And he himself is familiar with this animal.

　　In his eyes, Yunnan golden monkey with white face and red lips has a pair of "the most human-like face in the world" and "the most beautiful natural red lips in the world", which is one of the most beautiful animals on earth.

　　In many ways, Yunnan golden monkeys all behave like human beings. Long Yongcheng saw their "collective lunch break" at close range.

　　One afternoon in April this year, azaleas were in full bloom in Samage forest area of Baima Snow Mountain National Nature Reserve in Yunnan. A few minutes ago, more than 400 Yunnan golden monkeys, which were jumping up and down in the hemlock forest in Yunnan, more than 30 meters high, suddenly quieted down and all entered the lunch break.

　　Long Yongcheng and local monkey guard Yu Zhonghua, who were close at hand, did not dare to make any noise. They sat down on the spot and quietly accompanied the Yunnan golden monkey. They know that Yunnan golden monkey has the habit of taking a lunch break, usually between 12: 00 and 14: 00 every day.

　　Few people have such luck to accompany them. Yunnan golden monkey is a world-class rare animal endemic to China, and its population is extremely rare. It was listed as a national first-class protected species in the 1970s, and it is also an endangered species in the red list of IUCN species. It is only distributed in five counties of Deqin, Weixi, Lanping, Yulong and Yunlong in northwest Yunnan and the alpine primeval forest on the top of the snow-capped mountain in Mangkang County in southeast Tibet, and it is the highest-altitude primate in the world.

　　According to Ma Yuanye, a researcher at Kunming Institute of Zoology, Chinese Academy of Sciences, this mysterious snow mountain spirit first appeared in a report by a Frenchman in 1871, but the content of the report was based on hearsay. In 1890, two Frenchmen captured seven Yunnan golden monkeys in Deqin County, Yunnan Province, and the museum in Paris preserved their skulls and skins. Seven years later, French zoologist Miller Edward made a scientific description of Yunnan golden monkey for the first time based on these specimens.

　　However, in the following more than half a century, the mysterious Yunnan golden monkey lost news.

　　It was not until the 1960s that the Kunming Institute of Zoology, Chinese Academy of Sciences made a continuous scientific investigation of Yunnan golden monkey, which made people know that there were such beautiful, elegant and breathtaking monkeys in the world.

　　However, the Yunnan golden monkey with a "charming smile" is in a worrying living situation. In 2015, the Ministry of Environmental Protection and the Chinese Academy of Sciences jointly published the Red List of Biodiversity in China, which showed that the Yunnan golden monkey population was rare and its distribution area was narrow, belonging to endangered species. In recent years, through the establishment of nature reserves, artificial intervention grouping and other measures, the population of Yunnan golden monkey has steadily increased, but due to overfishing and hunting and habitat loss, the population and habitat of Yunnan golden monkey are still facing serious threats.

　　According to Long Yongcheng, although three national reserves and one provincial reserve have been established for Yunnan golden monkey, there are still some monkeys outside the reserve. For example, there are about 350 monkeys in Laojun Mountain in Lijiang, which are the most endangered among the three gene banks of Yunnan golden monkey, and are completely out of the reserve. There are more than 400 monkeys in Baima Snow Mountain Reserve, which has overflowed the reserve for more than 10 years. These problems need to be solved urgently.

　　Guo Huijun, deputy director of the Forestry Department of Yunnan Province, bluntly said that since the first scientific record of Yunnan golden monkey in 1897, the two geographical distribution and population surveys conducted so far were in the 1990s and 2005, and the scientific data need to be updated urgently.

　　A person’s 10 years

　　In the early 1980s, Long Yongcheng, who graduated from Sun Yat-sen University and was assigned to work in Kunming Institute of Zoology, Chinese Academy of Sciences, like other researchers in the institute, had never seen a live Yunnan golden monkey. At that time, "there was no photo of Yunnan golden monkey in the world".

　　Over the past 30 years, researchers from Kunming Institute of Zoology and other related research institutions have struggled and walked alone on the deserted barren hills with heavy bags on their legs, tracking the elves who are hiding from human beings.

　　Among these scientists, the most legendary is Long Yongcheng.

　　In 1987, after retrieving 15 Yunnan golden monkey skeletons from Deqin County alone, Long Yongcheng realized that this unknown peerless treasure was rapidly dying out.

　　At that time, Kunming Institute of Zoology had begun a systematic scientific research on Yunnan golden monkey. Long Yongcheng put forward the topic of investigating the geographical distribution and population number of Yunnan golden monkey, which was supported by the institute.

　　He underestimated the practical difficulties faced by this subject. The journey to find Yunnan golden monkey was so long and arduous that it took him 10 years to finish the project.

　　At first, most local forestry bureaus didn’t know whether there were Yunnan golden monkeys in China. Long Yongcheng, who was "half-hearted", could only ask fellow villagers in rural markets or villages and ask the hunters in the village to be guides.

　　In Deqin, Yunlong, Lijiang and other places in northwest Yunnan, most local people know Yunnan golden monkey. They call this kind of monkey "Daqing monkey", "White monkey" and "Flower monkey", which is different from another kind of monkey with yellow hair and short tail and likes to disturb crops. "This kind of monkey with nose facing the sky never steals crops."

　　However, the Yunnan golden monkey, which never disturbs people, has always been the target of local hunting. People eat their meat and exchange a monkey bone for nearly 100 kilograms of rice; They were made into swaddling clothes with their skins. According to Long Yongcheng’s explanation, "Yunnan golden monkey skin has anti-corrosion effect, and all three children brought up are intact. The swaddling clothes made of sheepskin will be corroded by urine and can only bring up one child. "

　　Monkeys living in the deep forests of steep canyons have a large range of activities and are very difficult to track. If you are lucky, you can see the monkeys waiting day and night on the mountain ridge or the fir tree 30 to 40 meters high in half a month or a month. If you are unlucky, you won’t see each other for a month or two.

　　The most difficult task is to establish a long-term field research base in Baima Snow Mountain Nature Reserve at an altitude of 4,300 meters. The so-called base is just a few simple wooden houses built on the alpine lawn. It is the establishment of this base that has enabled the scientific community to obtain valuable information about four Yunnan golden monkey groups in the region.

　　There is almost no communication and sound transmission between the monkeys in the reserve, and they are all in a state of "isolation". This self-protection makes it difficult for researchers to find them, especially some smaller monkeys.

　　Based on years of experience in finding monkeys in the forest, Long Yongcheng relied on feces to judge and track the whereabouts of monkeys. In Dashangou, northwest Yunnan, it took him 10 years to complete the accurate geographical location investigation and preliminary population estimation of Yunnan golden monkey, which laid an important foundation for later scientific research.

　　"Few people can match his understanding of Yunnan golden monkey." Qian Xiaohua, president of Alashan SEE Ecological Association, said.

　　Many years later, Long Yongcheng was invited to give a speech at the graduation ceremony of his alma mater, saying, "I have only done research and protection of Yunnan golden monkey for more than 30 years. For 10 years, I just searched for Yunnan golden monkey alone in the virgin forest of snowy plateau — — Of course, there is no competition in this kind of work. As long as you can persist, you will always gain something. "

　　Turn excellent hunters into excellent animal protectors.

　　Ten years ago, Zhang Zhimin, a former hunter, worked as a guide for Long Yongcheng to visit the monkeys in Laojun Mountain in Lijiang.

　　Now, he is a local Yunnan golden monkey guard. As long as he sees hunting condoms in the mountains, he can roughly judge who laid these condoms, what animals they were "laid" and what impact they will have on Yunnan golden monkeys.

　　When he was a guide for Long Yongcheng, after breakfast every day, the two of them put the leftovers in plastic bags and walked for more than ten hours in the desolate and low-visibility primitive alpine forest. Many times, I didn’t even have time to stop to eat. I didn’t go back to the camp built with branches until it was dark. I put the food I carried out and brought back back into the pot and cooked it with dinner.

　　After more than five months of inseparable outdoor life, we not only found out the range of activities and approximate population of the two monkeys in Laojun Mountain, but also turned Zhang Zhimin, a "hunter", into a "protector" of Yunnan golden monkey.

　　As an experienced hunter, Zhang Zhimin is familiar with all kinds of "animal paths" and "bird paths" in the mountains. He used the knowledge of hunters to deal with poaching, which made him famous. In order to protect the monkeys, he and the local villagers traveled all over Laojun Mountain. "The trip is enough to circle the earth." Their field tracking and patrol have enabled the monkeys to live a stable life. Today, the number of Yunnan golden monkeys in Laojun Mountain has increased from more than 100 to about 350. In 2013, Zhang Zhimin won the first prize of "Pioneer Award for Natural Environmental Protection" of Ford Motor Environmental Protection Award.

　　In Xiangguqing, a forest area in Samage, Tacheng Town, Weixi County, 120 kilometers away from Shangri-La, there is also a monkey guard team transformed from hunters.

　　The Monkey Guard was established in 1998. In the past 20 years, the team members have walked through the steep mountains and kept company with the monkeys in the ice and snow. "Everyone wears out three pairs of rubber shoes every month." After many hardships, we have mastered the basic activities of monkeys, realized the comprehensive protection and management of monkeys, and regularly fed Yunnan golden monkeys, which greatly increased the number of monkeys.

　　Nowadays, Xiangguqing, a tiny place with less than 100 square kilometers, has been home to nearly 1,000 Yunnan golden monkeys, making it the easiest place to see Yunnan golden monkeys in the world. Domestic and foreign dignitaries, researchers, environmentalists and tourists have come here to watch monkeys, and China wildlife protection has also attracted the attention and attention of the international community.

　　According to the experience of Laojunshan and Xiangguqing, Yunnan has established several routes in Baima Snow Mountain and Tianchi in Yunlong County, and Yunling Provincial Nature Reserve in Lanping County to carry out long-term patrol monitoring of Yunnan golden monkey.

　　"The hunter is a veritable zoologist. The fundamental way to protect wild animals is to turn excellent hunters into excellent animal protectors. " Long Yongcheng said.

　　Protecting Yunnan golden monkey protects more than 5% of the virgin forest in China.

　　In the investigation on Baima Snow Mountain, Long Yongcheng and the guide had to wear all the warm clothes such as duck down clothes, duck down vests and sweaters in the morning, and they were still shivering with cold. They dare not make a fire for fear of disturbing the sleeping monkeys.

　　At 7: 30, the genius lights up. The monkeys gradually wake up, and they begin to move and eat breakfast — — Feeding on the pineapples in the trees.

　　Usnea is a lichen fungus parasitic on the crown of fir, which lives by absorbing the nutrition of fir. Too much pine will affect the growth of fir. The fir forest provides food and shelter for the monkeys, and the monkeys remove excessive pines from the crown of the fir tree.

　　Scientists’ field research found that the hinterland of Hengduan Mountain, where Yunnan golden monkey lives, is the core of global biodiversity hotspots. The protection of Yunnan golden monkey is also the protection of virgin forest: protecting Yunnan golden monkey will protect more than 5% of China’s virgin forest.

　　In recent years, Yunnan has effectively protected Yunnan golden snub-nosed monkey populations and habitats to some extent by expanding protected areas, carrying out the rescue and protection of extremely small populations of wild species, promoting the reform of nature reserve management system, implementing the Yunnan Province Protection Action Plan (2015-2020), relocating residents in the core areas and buffer zones of protected areas, and investing special funds for rescue and protection.

　　Both the captive breeding experiment of Yunnan golden monkey in Kunming Animal Institute in recent 20 years and the field follow-up investigation by researchers show that the annual birth rate of Yunnan golden monkey population can reach more than 10%, sometimes as high as 15%.

　　"As long as there is no abnormal death, the number of monkeys will continue to increase, and small populations will not die out automatically." Long Yongcheng said.

　　At present, although there are fewer and fewer poachers, even sporadic poaching activities are unbearable for Yunnan golden monkeys with a population of less than 3,000.

　　Therefore, scientists including Long Yongcheng believe that the experience of monkey protection in Laojun Mountain in Lijiang and Tacheng Town in Weixi County proves that the whole process of tracking and protection is one of the most effective means to protect Yunnan golden monkey at present.

　　"The meritorious service of the Monkey Guard Team is as great as the research results of animal ecologists." Long Yongcheng said.

　　To this end, the public welfare funds donated by Alashan SEE Ecological Association to the "Yunnan Golden Monkey Dynamic Monitoring Project" are not only used for equipment improvement and capacity building of patrol officers, but also give priority to providing Himalayan bee breeding training, beehives and rare Chinese herbal medicine seedlings for patrol officers’ families, so that these people can diversify their family income sources and make them feel at ease.

　　However, while affirming the achievements of the monkey guard team, some researchers expressed their objection to the "monkey herding" of the Xiangguqing patrol team in Tacheng Town regularly feeding Yunnan golden monkeys, and thought it should be stopped. They are worried that years of special care may weaken the survival ability of Yunnan golden monkey in nature.

　　"This is a thorny problem." Long Yongcheng said that at present, the research on Yunnan golden monkey population is still very limited, and it is difficult to say which protection scheme is the most appropriate without a national survey. "If we don’t grasp the population number, dynamic changes, habitat conditions, threatened factors and protection needs of Yunnan golden monkey as soon as possible, it will be difficult to formulate scientific protection measures."

　　Fortunately, his long-awaited investigation has finally started, and the mystery of Yunnan golden monkey will be more clearly visible.

The first is the change in appearance. The new X1 adopts the latest family-style design elements, and the front face is changed with sharper line design. The area of the kidney-shaped front grille is further increased, and the headlights adopt the latest styling design, and the lower enclosure is redesigned, equipped with a large-size diversion groove design, which makes the front face of the new X1 look more fierce. The side shape is basically the same as the old model, and the tail adopts the layout of bilateral single exhaust, which makes the overall shape more fashionable and dynamic.

In the interior part, the new car adopts the latest design style, and the new car is replaced by a brand-new electronic bar shape. The car system is equipped with the sixth generation idrive human-computer interaction system, which adds touch function. In addition, the new car’s M multi-function sports steering wheel, double-round cool black instrument panel, electronic shift lever and sports seat with M logo are all made of black high-gloss material, which is more sporty as a whole.

The length of the car is 4616mm, the width of the car body reaches 1845mm, and the wheelbase is 2802mm, which is quite satisfactory. In the same class, the wheelbase of BMW X1 ranks 35th. This size exceeds most models in its class. The actual interior space performance is also very good. From the actual ride experience, the front and rear rows are relatively spacious. The design of skylight also increases the subjective space feeling of front and rear passengers. Among the models of the same price and class, the trunk volume of BMW X1 ranks 16th. The space is relatively regular, without obvious protrusions, and the overall loading capacity is good.

BMW X1M35Li adopts a 2.0 engine, with a maximum horsepower of 301 and a peak torque of 400, matching the wet dual clutch (DCT) gearbox. 2.0 engine with BMW X1 is quite satisfactory in power performance, with weak low torque and can feel hysteresis. The official measured acceleration of BMW X1 is 5.6S, ranking 28th among 250,000-400,000 SUV models.

The active/passive safety configuration of BMW X1 is complete, includingAutomatic parking、Zero tire pressure endurance tire、Automatic parking、Steep slope descent、hill start assist control、knee airbag、HUD head-up display、Anti-lock braking (ABS)、Braking force distribution (EBD/CBC, etc.)、Brake assist (EBA/BAS, etc.)、Traction control (ASR/TCS, etc.)、Active noise reduction、Engine start and stop、Side safety air curtain、Wireless charging of mobile phone、night vision system、LED daytime running lights、Forward reversing radar、Tire pressure monitoring、Steering wheel heating、Body stability control (ESP/DSC, etc.)、Rear reversing radar、Fatigue reminder、Remote parking、Child seat interface、Lane keeping (LKAS)Equal configuration.

Among them,Automatic parkingYou can avoid stepping on the brakes for a long time or needing to pull frequently;Steep slope descentCan safely pass through steep slope road conditions at low speed;knee airbagReduce the injury of the car interior to the occupant’s knees in the secondary collision.

If the above data and participation can’t fully understand BMW X1, then we can give you a more comprehensive reference based on the word-of-mouth information of users who have bought BMW X1 in history. It can be seen that what everyone is most satisfied with BMW X1 is its interior praise, and the spacious space and smooth body are also the points that everyone likes it.

　　After some e-commerce platforms entered the pre-sale period of this year’s "Double Eleven", the biggest express season in one year also kicked off. Beijing Youth Daily reporter recently found that this year’s express delivery company’s "rob people war" not only started as early as last month, but also some outlets opened the daily salary for temporary recruitment of couriers to 500 yuan.

　　Courier company grabs people.

　　Part of the daily salary is 500 yuan

　　"Recruitment of couriers, living nearby is preferred, and the salary can be settled daily. The salary is from 300 yuan to 400 yuan … …” A few days ago, Mr. Zhao, who lives in the East Third Ring Road in Beijing, found a recruitment notice posted on the little brother’s car that sent a courier to his home community. With the approach of "Double Eleven", there are more and more express delivery vehicles with recruitment notices, and some even bid the daily wage of 500 yuan. "I want to send a courier after reading it." Mr. Zhao said that this is much higher than his current job salary.

　　At the rookie direct delivery station in Jiangcun, Hangzhou, the site has been continuously recruiting people. The stationmaster Peng Dengzhong said, "The site intends to supplement 25 capacity, and it has also increased the dispatch fee. The dispatch fee of 3.15 yuan/single plus the subsidy for heavy parts can easily exceed 10,000 yuan. Now 18 people have been recruited, most of them are after 00. "

　　Peng Dengzhong is also using car stickers to recruit workers. The effect is obvious, and the recruitment crowd is very accurate. They are all residents of nearby communities and are familiar with the geographical environment. Gong Yajing, a new courier, said, "The income here is quite stable. I heard that ‘ Double eleven ’ It is the time when the courier makes the most money. The stationmaster said that there are still subsidies. It is almost the end of the year, just to earn more money, so I came. "

　　Not only offline recruitment, Beiqing Daily reporters saw on some local recruitment platforms that the posts for recruiting couriers, sorters and packers have increased recently, and the conditions for opening them are much more generous than in previous years. It is already the basic operation of recruitment for courier companies to type "food, accommodation" and "free car" in recruitment information. Some companies have typed "only delivery without packaging and sorting", and some even clearly marked "only one point is required". In terms of treatment, the posts recruiting couriers online all started with a salary of 9,000 yuan, and some reached an upper limit of 15,000 yuan. And some posts that recruit long-term couriers also play such additional benefits as "two weekends a week", "marriage leave" and "salary can be advanced".

　　The reporter of Beiqing Daily noticed that public information showed that the recruitment demand of express sorters in the same city and market platform ranked ninth in the third quarter of 2022, up 69.27% year-on-year.

　　Fight for service during the "Double Eleven" period

　　Forcing the industry to retain people with high salaries.

　　The reporter of Beiqing Daily learned that this year, many express delivery companies strive to improve their terminal service capabilities during the "Double Eleven" period. One of the "sharp weapons" is the promise of "home delivery". For example, during the "Double Eleven" period, Shentong launched on-demand delivery services in 30 cities where online shopping is active, including couriers who will take the initiative to standardize telecommunications with customers and deliver them to the door for users to sign for. Rookie is to increase the intensity of door-to-door delivery through self-operated logistics rookie direct delivery (Dan Bird), joining rookie station and joint Shentong Express. Jingdong Logistics said that through intelligent technology such as five-level address fence, it can guarantee the undifferentiated door-to-door service across the country and reach the fastest time in over 200 cities. SF even announced on September 5th that 50 cities across the country, including Beijing and Shanghai, "failed to deliver the goods and promised to pay".

　　All these measures need more people at the end site to complete. According to statistics, the rookie will increase 100,000 short-term workers in this "Double Eleven". According to the data previously revealed from the rookie, it is expected that this year’s "Double Eleven" express delivery volume will hit a record high. The gap of express delivery practitioners needs to be filled, and the monthly salary of 10,000 yuan is expected to continue throughout the express delivery season.

　　"Looking at the treatment is good. In fact, it is not easy to recruit people." The person in charge of a express delivery station in Chaoyang District said that it has been preparing for the arrival of the peak season since September, and it has been recruited for more than a month, and it has not filled the expected number. In order to recruit people, the person in charge also made efforts internally, promising that the existing courier would give a red envelope reward of 200-300 yuan if he could recommend people to the site, and if the recommended person could work for two months, the recommender could get another red envelope.

　　"There are quite a few people who come to inquire. Many people give up when they listen to the length of work every day. Others left in less than ten days. " The person in charge said that it has not yet entered the real peak season, but the number of express delivery has also increased a lot compared with the beginning of the month. The current state is from 7 am to 7 pm. According to the situation of "Double Eleven" in previous years, it is estimated that I have to work for about 16 hours a day when I am really busy. Not only that, in recent years, the "Double Eleven" front has become longer and longer, and the distribution peak has also been extended, so we can only rely on high salaries to retain people.

　　China Express Association revealed

　　This year’s express season will reach 82 days.

　　The reporter of Beiqing Daily learned that in order to cope with the upcoming peak season of express delivery, China Express Association organized a mobilization meeting for the coordination of express delivery service guarantee on October 25. It was revealed at the meeting that this year’s peak season of express delivery business began in early November and ended on the eve of the Spring Festival in 2023, with a total of 82 days.

　　In terms of the timeliness of express delivery, Zhongtong said that orders delivered during the promotion period will be given priority to collection, transfer and delivery. ZTO Express’s transshipment centers in Ezhou and Jingzhou, Hubei, Hefei, Anhui, Yinchuan, Ningxia and Liuzhou, Guangxi have all been relocated and upgraded, further improving the production capacity of the whole network; Yuantong has introduced payment, performance guarantee, price commitment and customer service guarantee. Shentong predicts that the daily average number of trains will increase by 80% and nearly 500 direct routes will be added; The rookie has an additional storage of more than 4 million square meters in more than 20 cities across the country, including opening an epidemic backup warehouse to support businesses to open warehouses in 7 days.

CCTV News:Entering the era of big data, I believe many people have this experience, not the tourist season, but the ticket price is getting higher and higher; When chatting, I casually mentioned a certain product, and when I turned around, I saw the advertising push of related products on major platforms. In the Internet age, we can quickly find the information we want, but the information and data about ourselves seem to be more easily leaked or illegally used by businesses without our knowledge. The following is a case in which consumers are "killed" by big data.　

Not long ago, an article that questioned the use of algorithms by a take-away platform to "kill cooked food" sparked heated discussion. A member user of the platform pointed out that his delivery fee is often higher than that of non-member users for the same order. What was going on at that time? The reporter contacted Mr. Xiao, the author of this article.

Mr. Xiao:"I often order the same takeaway, and suddenly one day I opened a member and found the delivery fee price.Compared with beforeIt has tripled in one fell swoop. It used to be two yuan or free, and then I tried it for almost an hour from 12 noon to 1: 30 pm that day, and the delivery fee was always higher than usual, which was six yuan at that time, and then suddenly caught my attention. "

Mr. Xiao told reporters that in the following week, when ordering takeout, he often used two mobile phones at the same time to log in to member accounts and non-member accounts for comparative experiments, and found that the difference in delivery fees always existed. So he summarized these observations into an article and published it in his personal WeChat official account.

Mr. Xiao:"Later, after my article came out, many netizens left messages in the background and met this kind of member ‘fool friends or acquaintances in business’ The situation. For example, a single item and a mouse, I bought it in 100 yuan when I was not a member, but I bought it with a member.The price became 110 yuan. After I open a member, the price is higher than that of a non-member, so what is the significance of my opening a member? "

After the article sparked a heated discussion, the relevant take-out platform contacted Mr. Xiao. In response to his query, the platform gave the reply that the price difference in delivery fee was an error caused by system cache.

Mr. Xiao:"I have tried many times, and this is the case within a week. That cache statement certainly doesn’t make sense.Where is the location cache? In the same place, the difference is between members and non-members. I consulted some technical friends, and it is true that the error of this cache is within five meters, but it is impossible to cause such a big error. "

Mr. Xiao’s doubts finally failed to get a clear answer. However, his experience has brought the topic of "killing" big data into the public’s field of vision again. So what is behind the "killing" phenomenon of big data?

360-degree accurate portrait The platform collects a lot of personal data.

According to experts, the most critical step in killing big data is to be very familiar with customers, and thus provide differentiated choices. This has already existed in some previous business models, and there are few negative comments.

Pei Wei, Associate Professor, Beihang University School of Law:"As far as big data killing itself is concerned, it is actually differentiated pricing behind it. For example, in insurance, different people may guarantee the amount or amount of money, or the compulsory period of insurance will be different. Therefore, if we simply use differentiated pricing, it does not necessarily constitute a negative thing. What we are disgusted with is differential pricing without a legitimate basis. "　

According to China Consumers Association, consumers are interested in big data.“The core of the problem is the application of algorithm technology on the Internet platform, which is embodied in recommendation algorithm, price algorithm, evaluation algorithm, ranking algorithm, probability algorithm and traffic algorithm.

Jian Chen, Director of Complaints Department of China Consumers Association:"For example, when a consumer buys goods or services, the platform will form some personalized recommendations for him according to some browsed pages of the consumer or some preferences of the consumer, including his whereabouts. In fact, the operator may have made some accurate personal data portraits of consumers. According to this portrait, the relevant goods and services are only recommended to him, so his right to know is very flawed. "

How is the Internet platform "familiar" with every user? The answer is through user portraits. Behind the accurate user portrait is a large amount of personal data accumulated by the platform.

Liang Zheng, Vice President of Tsinghua University Institute of Artificial Intelligence International Governance.: "With my data, you finally made such a portrayal of me. Is this accurate? If it is too accurate, people will worry about being manipulated. After a little in-depth discussion, I will find that what I care about is its own discriminatory pricing, or is my information reflected behind it improperly collected and used? "

"APP eavesdropping" technology can be realized, but the cost is high.　Low efficiency and high legal risk.

User portraits based on big data can let merchants find out whether you like spicy food or sour food, and rank restaurants that are more in line with your taste through algorithms. User data is often collected by the Internet platform through one mobile APP. In the process of dealing with these APPs, there are also problems that worry everyone, such as the phenomenon of "APP eavesdropping" that we often hear. So does "app eavesdropping" exist?

The APP Governance Working Group consists of a group of cyber security legal and technical experts from the National Information Security Standardization Technical Committee, China Consumers Association, internet society of china and China Cyberspace Security Association.

Technical experts first demonstrated to us whether the APP can eavesdrop technically and what might happen if it eavesdrops through a simulated "APP eavesdropping test program" developed by them.

"We will now enter this test. If we make a speech like this, what happens when the hand is released? The recording actually continues. In fact, we can remove this hint, and the whole process of the test is two minutes. "

Two minutes later, we can see that a 120-second speech was generated in the test program. After the technicians export the voice data, after checking, it is confirmed that "eavesdropping" can be realized when the test program is placed in the foreground.

In addition, after a comparative experiment, the technician told us that the recording can continue for a period of time when the test program is back to the background or the mobile phone is locked, but it will terminate automatically. Just different mobile phone operating systems, the duration of continuous recording under lock screen is slightly different.

Then, is the technically achievable "eavesdropping" method abused in the APP on the market?

Expert of APP Governance Working Group He Yanzhe:"When we actually do this kind of detection of eavesdropping, we found that we haven’t found any APP that has this eavesdropping behavior after uploading voice information."

According to experts from the APP Governance Working Group, although it is technically possible to sneak shots and sneak recordings, this method is costly, inefficient and has high legal risks.

Experts from the APP Governance Working Group said that at present, both the industry standard and the technical level are further strengthening the transparency of calling sensitive rights such as mobile phone microphones, so as to let mobile phone users know.

Expert of APP Governance Working Group He Yanzhe:"Now we see that there are some mobile phone operating systems that have realized real-time prompts for the use of microphones. We call it a recording indicator, which means that when you want to call this microphone, there is a status bar, a red dot or a reminder. "

Accurate platform recommendation is the result of multi-channel aggregation accumulated all the year round.

I just chatted with my friends about the fitness plan, and in a blink of an eye, online shopping platforms began to recommend fitness products to you; Or search for the bottom materials of the overheated pot on a platform, and many platforms have started to recommend the ingredients of the shabu-shabu and even the pots and pans to you frequently. How is such an accurate personalized recommendation achieved?

Expert of APP Governance Working Group He Yanzhe:"An APP, we say that it can make a 360-degree portrait of a user. This portrait, I believe, is the result of years of accumulation, which is the first; Second, it is the result of convergence of multiple channels. "

According to experts, the accuracy of the portrait is mainly achieved through big data analysis of our purchase records, browsing records, search records, and even downloaded application lists.

Expert of APP Governance Working Group He Yanzhe:"Why do you say that sometimes you feel eavesdropped? Providing this source of big data, it is not the current APP, it may be other apps. You have done some operations, it will aggregate the corresponding information together, and it may also associate your friends and people in the same area. Then they have some actions, and it may also become a direction for it to push advertisements. "

Experts suggest that users can find the microphone permission in the permission settings of the mobile phone operating system and check which apps are currently authorized to use the microphone. According to their own needs, users can turn off the authorization to use the microphone for the APP at any time.

More attention should be paid to the illegal collection of personal information by APP.

When the experts of the APP Governance Working Group tested the APP on the market, they also found many problems, such as the long privacy policy, the difficulty for users to understand and the inability to cancel accounts.　

"Let’s give an example. In the process of testing, we found that this wallpaper APP has a privacy policy of more than 10 thousand words. Then let’s see what it says. I believe that no one will finish reading this privacy policy. Even people like us who read privacy policies every day have a headache. For example, this location information written in this privacy policy. The APP said that I want location information. It said a lot of reasons, but I don’t think this reason has anything to do with wallpaper. "

Pei Wei, Associate Professor, Beihang University School of Law: "Whether the privacy policy really serves users or really protects individuals is actually a broken state. Therefore, what is more worrying in the future is the formalization of this protection. "

The APP Governance Working Group has a WeChat WeChat official account platform for "APP Personal Information Reporting" and a dedicated reporting mailbox. Experts told reporters that the difficulty of account cancellation is another problem with a large number of complaints from users at present.

"Take a look at this APP first. There is an account cancellation function. I click to enter my information, and then I find the following sentence is ‘ There is ink balance in the account. Cannot cancel ’ . After I clicked on it, I found that there were 20 virtual coins, which were given by me when I newly registered, and I didn’t buy them myself. I thought, can I use it? It says 49 ink coins. But I only have 20, that is, I have to make up the money, and I will never be able to divide that number. So I can never cancel it. "

Ding Xiaodong, deputy dean of the Institute of Future Rule of Law of Renmin University of China: "From the research of information law, we often have a term called ‘ Digital branding ’ . In this network society, all the footprints are permanently marked. In our country’s personal information protection law, there is a special provision. We say that from the legal rights and interests, it belongs to an individual’s right to delete. "

Pei Wei, Associate Professor, Beihang University School of Law:"The national standard for information technology security, which involves the personal information security specification, specifically mentions this cancellation. That is to say, when you log off or stop using a certain service, its ways and means should be the same as when you use this service. Then at the same time, the information you are required to provide during the logout process should not be more than the information you use and the identity information you provide when using the App. "　

According to experts, the collection of personal information is only one of the links in the circulation of data elements. Protection of personal information security, data storage, processing and circulation also need attention.

Ding Xiaodong, Vice President of the Institute of Future Rule of Law of China Renmin University:"If the front-end link (data collection) is closed, it will actually have a great impact on the development of artificial intelligence and data industry. Then how to reconcile? I think a very important aspect is that after the collection of personal information, it must be managed in a very strict life cycle. We should have an anonymous mechanism and a fuzzy mechanism. When processing, we may have to adopt some principles of data minimization to process the necessary data. In particular, a very high standard should be adopted in the aspects of storage and circulation and the protection of leakage. "

The security boundary needs to be explored by the users of the regulatory platform.

Nowadays, the convenience brought by technology and the protection of personal information are at the two ends of a swinging balance. What role does the law play in the process of "balancing" this balance?

Ding Xiaodong, Vice President of the Institute of Future Rule of Law of China Renmin University:"Our traditional consumer protection law also includes the application of contract law to standard terms, the application of tort law to infringement issues, and many problems in administrative supervision. All these laws can be invoked to a certain extent. But on the other hand, many problems are caused by new technologies such as personal information and algorithms, so to some extent, there are still some shortcomings, and the legislature is actively following up. The entry into force of our civil code may provide a lot of legal support for the protection of personal information. Then the formulation of the Personal Information Protection Law (draft) and the Data Security Law (draft) will certainly provide a lot of additional protection in the future. "

Nowadays, each of us is producing a lot of information. Experts said that in the current social life driven by algorithms and big data, the law plays more of a role of protection. The delineation of security boundaries needs to be explored by regulators, platforms and users in interaction.

Liang Zheng, Vice President of Tsinghua University Institute of Artificial Intelligence International Governance: "From the perspective of laws and regulations, it should be the bottom, and then we draw some red lines, which cannot affect public safety. Even some business models like the digital economy are iterative very quickly, and we can’t wait until the law is enacted. For each problem, there can be corresponding technical solutions to deal with it. It is not unsolvable. The key is that we should make the rules clear. "

Why do I like movies, but I can’t get into graduate school?

　　Catch up with the holidays, it is rare to have a rest, and always get together with friends and relatives. China’s wine culture has a long history. At the dinner table, there is a lot of money, and you come and go, which not only brings closer feelings, but also enlivens the atmosphere. Recalling the past, talking about the future, drinking a little wine, feeling high, talking more, blushing cheeks, and racing heartbeat are all normal physiological reactions. But some people have poor self-control, and excessive drinking will lead to sudden arrhythmia and palpitation. What’s more, sudden death occurred during drinking, and the happy event turned into a funeral. This sudden arrhythmia often happens after drinking alcohol on holidays, hence the name "holiday heart syndrome". Seeing that the National Day is coming, let’s take it easy.

　　Philosophers say well that nothing can be separated from the three logical thinking processes of "what", "why" and "how to do it" Today, according to this logic, let’s take a look at what "holiday heart syndrome" is all about.

　　Heart events on holidays are 6-8 times as high as usual.

　　"Holiday Heart Syndrome" was first named by an American cardiologist Ettinger in 1978, and then gradually improved, forming such a concept: acute heart injury syndrome with arrhythmia as the main feature, which appeared during holidays. It can be seen that this disease is closely related to drinking, and often appears after drinking and having fun during holidays or winter leisure, not only in patients with original heart disease, but also among people without a history of heart disease.

　　Let’s look at its main clinical manifestations. Atrial fibrillation is the most common, and patients will feel that the heart beats very quickly and irregularly. Others such as atrial flutter, junctional tachycardia, ventricular premature beats, atrial premature beats, atrial escape, paroxysmal atrial tachycardia and ventricular tachycardia can all occur. Mild people may have chest tightness, shortness of breath, atypical chest pain symptoms, palpitations, and severe people may have dizziness or syncope. More serious, heart failure and sudden death may occur.

　　The most terrible thing is that because of its atypical symptoms, "Holiday Heart Syndrome" is easily misdiagnosed as coronary heart disease and viral myocarditis. The high misdiagnosis rate has brought some difficulties to clinical diagnosis and treatment. Therefore, early diagnosis and timely treatment are particularly important.

　　There are many cardiac events in holidays, which can reach 6 ~ 8 times as much as usual. Tracing the cause, this syndrome has nothing to do with a long history of heart disease, and the root of it lies in drinking. Excessive drinking of wine, beer or spirits will delay the conduction time of myocardium due to alcohol and its metabolites, leading to reentry, or stimulate the release of norepinephrine from myocardium, thus changing the refractory period of myocardium. The acute damage of heart caused by alcohol (mechanical function or hemodynamic and electrophysiological changes) has been confirmed by many scholars. These factors will make excessive drinkers prone to rapid arrhythmia, resulting in premature beats, paroxysmal tachycardia, and even atrial flutter or atrial fibrillation and other abnormal heartbeat rhythms.

　　No matter how happy you are, you can only drink and save your life.

　　During holidays, how to protect your heart while releasing happiness and avoid accidents?

　　First of all, don’t be too tired before holidays. Especially the empty nesters, who are immersed in the joy of family reunion and are in a state of excitement and busyness, are prone to high blood pressure, dizziness, chest tightness and poor sleep. Look out! These may be the precursors of "holiday heart syndrome". Different from the elderly, young people take a break before holidays, work overtime continuously and have a bad rest. There are also some young people who work and rest irregularly every day during holidays. They don’t sleep until three or four o’clock in the evening, even they don’t rest all night, and they sleep until noon during the day. This situation is more likely to cause heart damage. Therefore, it is suggested that the old man and mother should not be too tired or too excited before the festival and control their emotions; Young people should arrange their work and leisure reasonably, and don’t stay up too much.

　　Secondly, establish a scientific and reasonable outlook on life. In modern society, the pace of life is fast, and many people usually lack exercise. During holidays, gathering with relatives and friends is easy to overeat and drink too much, which leads to excessive physical load. It is suggested that everyone should persist in exercising, enhance their physical fitness and establish good living habits. Don’t wait until there is something wrong with your body before thinking about exercising.

　　Third, drink in moderation, just a little. During the holidays, relatives and friends get together, and "a thousand cups of wine are few" and "a deep feeling is boring". Excessive drinking has become the norm at the party. But it is precisely excessive drinking that may bring the load to the heart and body to exceed the limit. It is recommended that you drink a little to avoid acute myocardial injury.

　　What should I do if "Holiday Heart Syndrome" suddenly happens?

　　1. Stop drinking and rest to prevent further symptoms from aggravating, causing serious arrhythmia or heart failure.

　　2. Go to the nearest hospital in time and give intravenous infusion to promote the timely discharge of alcohol and reduce the damage to the heart.

　　After hospital treatment, especially 6-12 hours after stopping drinking, arrhythmia signs can disappear, heartbeat rhythm and frequency return to normal, and the general prognosis is good.
