Encountered ＂big data killing＂？ Please keep this guide to avoid the ＂pit＂
Can the new "algorithm recommendation" rule block the "big data killing" loophole? Is there a better way to protect personal information? How to avoid the pit of "false planting grass"? In 2022, the theme of the year of consumer rights protection organized by the National Consumers Association is "promoting consumer equity together", and guiding the value concept of "science and technology for goodness" is one of the important contents. On the occasion of "March 15", Guangzhou Daily reporter interviewed Guangdong Consumer Council and its legal adviser to help consumers "avoid the pit".
The new rules of "big data killing" and "algorithm recommendation" are more targeted.
Recently, the Beijing Consumers Association released a survey on the "killing" problem of Internet consumption big data, which showed that among 32 samples of simulated consumption experience conducted on 16 platforms, the prices of new and old accounts were inconsistent in 14 samples. Among them, most of the samples have different final transaction prices because of different discounts or preferential treatments. However, the experience samples of individual online travel and take-away platforms show that new and old users buy the same goods (services) at the same time at different prices, which is suspected of infringing consumers’ legitimate rights and interests.
The survey found that the problem of "killing" big data mainly focuses on online shopping, online travel, take-out and online car rental.
Lawyer Chen Beiyuan, the legal adviser of Guangdong Consumer Council, believes that the Internet platform has mastered a huge amount of data, and it has made an accurate portrait of every consumer and made a "tailor-made" marketing plan based on the consumer’s consumption behavior, consumption habits, payment ability or consumption demand. The good aspect of this "tailor-made" is that it is more conducive to the effective allocation of resources and the provision of personalized consumer products. However, consumers are also easy to fall into the "information cocoon" provided by merchants, so consumers lose the ability to obtain more information, and a series of rights and interests such as informed consent, choice and fair trade rights of consumers are infringed.
If you encounter "big data killing", what are the "new tricks" for consumers to defend their rights? According to Chen Beiyuan, consumers can save evidence in time by taking screenshots or recording videos. If negotiation with the merchants fails, you can complain and report to the consumer association or relevant departments to safeguard your legitimate rights and interests according to law.
In addition, the "Regulations on the Administration of Algorithm Recommendation for Internet Information Services" ("new algorithm recommendation") implemented on March 1 this year is more targeted, which can give specific guidance to the administrative law enforcement of network information departments and other departments. From the consumer’s point of view, when the rights and interests are infringed, there is no doubt that there is an additional channel to complain to the online information department on the basis of consultation with merchants, complaints to consumer organizations, complaints to market supervision departments, and lawsuits to courts. "Now, for the supervision of the Internet, the responsibilities of the network information department are becoming more and more perfect, and complaints can also be made to the network information department in case of related violations of consumer rights." Chen Beiyuan said.
Personal information protection businesses should follow three principles in obtaining personal information.
Many merchants induce individuals to scan the code to provide personal information by giving gifts or coupons. In Chen Beiyuan’s view, this is also illegal. "The law has drawn a line: necessary, reasonable and legitimate, and merchants must follow these three principles when obtaining personal information." Chen Beiyuan pointed out that after the promulgation of the Personal Information Protection Law, all parties have a more powerful "legal weapon" for the protection of personal information.
For example, consumers can appeal for rights protection based on the rights granted to them, including litigation. Consumer organizations can make consumer public interest litigation based on legal empowerment, procuratorial organs can bring relevant public interest litigation, and administrative departments can impose administrative penalties according to legal provisions. "The behavior of market players is standardized, and the degree of protection of consumer rights will be higher."
So how to protect personal information? The Consumer Council of Guangdong Province and Chen Beiyuan gave "four important" suggestions: First, we should pay attention to the protection of our personal information, study the personal information protection law seriously, master the legal requirements, and learn to use legal means to protect personal privacy.
Second, we should develop the habit of "not providing unless necessary", and don’t arbitrarily authorize the provision of personal information for petty gain. When accepting the services of operators, it is necessary to clarify the way, scope, purpose and basis for operators to collect personal information, and not to provide personal information to operators easily unless necessary.
Third, we must protect our personal information. It is not easy to "sun" the content and materials related to personal information on the Internet. For some materials that are easy to leak their own information, such as express delivery and take-away orders, they should be properly handled in time.
Fourth, we should take the initiative to use legal weapons to safeguard our own rights and interests. If consumers’ personal information rights and interests are infringed, they can call 12345 and 12315 to complain and reflect, or log in to official website of Guangdong Consumer Council to complain about rights protection.
"False Grass Planting" False "Grass Planting Notes" are actually advertisements.
According to "Daren’s Notes on Planting Grass", I went to "punch in", only to find that the goods were not on the right board … … In recent years, some fictional consumption experiences such as "notes on planting grass" and "online celebrity evaluation" mislead consumption and overdraw consumers’ trust. Chen Beiyuan pointed out that in the past, online shopping platforms had "false praise", which made consumers switch to "diaries" and "evaluations" of some consumers, but now these evaluation articles under the banner of consumer experience have also appeared fictional. In his view, if the purpose of such evaluation articles is marketing and shopping guide, it is actually an advertisement.
Therefore, Chen Beiyuan believes that such articles should also abide by the provisions of the advertising law, including no misleading statements and no false propaganda. In addition, online celebrity, who made this kind of evaluation, should also bear the corresponding legal responsibilities. If it constitutes false propaganda and consumer fraud, he may face the legal responsibility of "returning one and losing three".
So how should consumers "avoid the pit"? Chen Beiyuan pointed out that consumers should try to compare in different businesses in different ways and obtain information in a diversified way. "Shop around and get rid of the ‘ Information cocoon room ’ 。”
Chen Beiyuan pointed out that if consumers conduct consumption behavior based on evaluation articles and later find that the goods are not right, consumers can complain or sue the merchants and online celebrity. "online celebrity often tells consumers which brand it is, or tells them the purchase link. Whether it is to provide brands or links, once the goods are not right, consumers can sue online celebrity and the merchants together, and the court will judge whether there is a shopping guide in online celebrity. "
Chen Beiyuan said that for consumers, they can provide evidence such as browsing records and purchase records to the court, and they can also apply to the court for an investigation order and order relevant platforms to provide relevant data. Or the court will allocate the burden of proof, and if the judge thinks that the merchant has this information, he needs to bear the burden of proof. (Guangzhou Daily, all-media reporter He Yingsi)

Hundreds of modified cars gather in Shanghai, and Wuling Hongguang MINI EV wins the post-90s market
As the saying goes, "Be famous as soon as possible" – the Wuling Hongguang MINI EV, which went on sale at the end of July last year, may have perfectly exemplified the meaning.
In August 2020, Wuling Hongguang announced that the MINI EV sold 15,000 in just 20 days.
In January 2021, Wuling Hongguang MINIEV lived up to expectations and attacked Tesla Model 3 all the way with the monthly sales of 37,000 vehicles, standing on the "top of the world" of the electric vehicle market;
Up to now, Wuling Hongguang MINIEV, which has been listed for 200 days, has announced that sales have exceeded 200,000…
Perhaps in the eyes of many people, the "ultra-low value" of less than 40,000 yuan is an important weapon for Wuling Hongguang MINI EV to gain market share, but the electric vehicle market has never lacked low-priced micro-electric vehicles. Why can Wuling reproduce the "explosion"?
In fact, micro-electric vehicles have been equivalent to "old man music" in the minds of consumers for a long time. Due to cost issues, their performance in battery life, quality, and configuration is not outstanding, but at least they can be licensed to solve transportation needs.
However, Wuling Hongguang MINIEV can still provide relatively good product power while achieving cost control. In addition to the production process adhering to the consistent level of Wuling Hongguang, the configuration, high-strength steel, battery thermal management, EPS, ABS, EDB, reversing radar, child seat interface, tire pressure monitoring are also not pulled down, which can be described as "small and complete".
What’s more interesting is that the Founder’s cute exterior design of this mini car leaves a wealth of room for modification, allowing consumers to unleash the personalized needs of this market segment.
On March 4th, the Hongguang MINI EV owner’s ceremony with the theme of "Putting on a Tone, Chaochuang Festival – A Small Paradise for Adults" was held in Shanghai. A total of 100 modified Hongguang MINI EVs showed everyone the chaochuang charm of this small car.
According to Wuling, at present, the trend rate of Hongguang MINI EV has reached 72%, making it the new energy vehicle with the highest trend rate in China. The trend rate of both appearance and interior is more than 50%. In particular, according to Wuling’s official data, the proportion of users born in the 1990s of Hongguang MINI EV has reached 72%, and the trend of younger generation is very significant; female owners account for more than 60%.
This has also led to a large number of "modified posts" about Hongguang MINI EV on social platforms such as Xiaohongshu and Weibo. Especially on the Xiaohongshu APP, the topic of "Wuling Hongguang MINI EV Renovation" has received tens of millions of views.
This also means that for many owners who prefer Hongguang MINIEV, it is no longer just a car, but a fashion trend item with social attributes through its personality.
In order to further respond to the enthusiasm of the majority of users and fans for the appearance/color, on the day of the owner’s ceremony, Wuling also announced the official cross-border cooperation of WULING × PANTONE UNIVERSE at the event, and jointly released Wuling Spring – white peach powder, avocado green, lemon yellow.
It is reported that PANTONE UNIVERSE is a globally renowned authority specializing in the development and research of colors, and the Wuling brand is the first national car brand to jointly release colors with it.
From the rapid "popularity" of Wuling Hongguang MINI EV, it is not difficult to see that for some limited license cities, unlimited travel, higher traffic efficiency and low price have undoubtedly hit the fundamental "pain point" of consumers buying cars. In addition, Wuling starts with personalization, rich color scheme and modification space have added a bit of unique interest to this car, making it a national scooter suitable for all ages.

The original exposure revealed that Deng Chao was suspected of depression, and his family came forward to confirm that the account was suspended for 23 days. Previously, the new movie lost 3.
Recently, the news of actor Deng Chao’s suspected depression was exposed on the Internet, which attracted widespread public attention. His cousin’s family, Deng Chao, came forward to confirm the news and expressed great concern about Deng Chao’s physical condition. It is understood that Deng Chao has been feeling down recently and has lost contact with his family and friends. The reason why Deng Chao’s cousin made a public statement on the Internet is to use everyone’s strength to help Deng Chao get through this difficult period.
Depression is not uncommon in the entertainment industry. Veterans like Chen Baiqiang and Leslie Cheung, as well as new-generation stars like Qiao Renliang and Coco Lee, have all suffered from depression. They usually look glamorous, but in fact they are miserable because many viewers do not understand the dissatisfaction behind them.
Some netizens noticed that Deng Chao’s social platform has not been updated for 23 days, whether it is work or life. This makes it difficult to connect this Deng Chao with his usual cheerful and cheerful self. Many people got to know Deng Chao’s "Running Man" through this show. He always shows a lively and cheerful personality in the show. Even when he is laughed at by the guests, he always looks optimistic. This also makes him win a lot of fans in the show.. Therefore, it is even more serious that Deng Chao’s cousin is so open about Deng Chao’s suspected depression. Otherwise, the family will not ask the Internet for help. During the summer vacation, Sun Li took his two children on vacation overseas, but Deng Chao did not. Taken together, this may mean that Deng Chao’s recent state is quite bad.
It is difficult for the public to accept the news that Deng Chao is suffering from depression, because Deng Chao has always been a very good character. However, recently, Deng Chao’s wife, Sun Li, updated a post on social media, posting a yoga video dedicated to psychological training, claiming that doing so can improve both mentally and physically over time.. Although she did not explicitly say that this is a practice designed for depression patients, it still brings people to mind depression. Many people suspect that Sun Li hopes to help Deng Chao build confidence through yoga and recover as soon as possible.
It is understood that there is a reason why Deng Chao is suspected of suffering from depression. Recently, he turned into a director and directed his first film "Chinese Ping Pong". However, the film lost 300 million yuan. The production cost of the film was as high as 350 million, but for various reasons, only 100 million of the box office revenue was received. Coupled with the commissions charged by the producers, the film eventually lost 320 million and became one of the most profitable films to date. At first, "Chinese Ping Pong" had a good reputation, but later due to the continuous withdrawal and the change of the release time, the box office only took 100 million. Perhaps, domestic audiences prefer big-scale productions with suspense or ups and downs, and may be a little resistant to movies like "Chinese Ping Pong" that recall the past.
In any case, Mr. Deng’s cousin’s revelations about his suspected depression are not groundless. Mr. Deng’s career has stabilised in recent years, even if the emotional impact of the loss of new films is not taken into account. However, everything will pass, and the most important thing is to calm down. The public has doubts about Mr. Deng’s illness and hopes that he will recover soon and return to the image of optimistic sunshine in the eyes of people.

Sun Jiadong： Create a ＂China Star＂ for a lifetime
An unforgettable lesson: quality is the life of spaceflight
Dongfeng-2
On March 21, 1962, our country’s first independently developed ballistic missile, "Dongfeng-2", was launched from the Jiuquan Satellite Launch Site. Unexpectedly, the missile lost control soon after takeoff, and finally crashed into the Gobi, only 300 meters away from the launch tower, blasting a large crater with a diameter of 30 meters.
All the test participants were dumbfounded. Lin Jin, the chief missile commander of the "Dongfeng No. 2", circled the crater created by the missile and said in tears, "This crater is mine, I’m going to bury it here."
The fall of Dongfeng-2 (source: video))
Many years later, Sun Jiadong couldn’t let go of the failure.
Sun Jiadong:"It fell, a few hundred meters away from you. I didn’t have the slightest idea in my head that I would come down if I made this thing up? At that time, I was dumbfounded and confused. Especially when you are in the big desert, you are standing in the east, and the launch point is exactly in the west. At that time, the sun has already set, and half of the sky is red."

In order to find out the reason for the failure, in the icy desert, hundreds of people bent over and fumbled inch by inch, looking for the fragments of the missile. Some people couldn’t help but wipe tears while picking it up. For several days, the sand was almost peeled off, and Sun Jiadong and his colleagues found all the fragments and reassembled the missile. Check one by one, and they found the root cause of the failure.
Sun Jiadong:"In the end, I found that a wire was broken, and there was more than a meter left. After an X-ray, it was broken inside. It was in such a few big failures that I realized that quality is life, and quality is everything in aerospace."
Every time he launched, sitting in the command hall, Sun Jiadong loved to hear the word "normal". Behind every "normal" was the high recognition of all astronauts that "quality is life", and they always maintained a strict, careful, meticulous and practical work style.
At 18:05 on October 24, 2007, the Long March 3A carrier rocket carrying our country’s first lunar exploration satellite Chang’e-1 was launched from the No. 3 tower of Xichang Satellite Launch Center. (Source: Shanghai Securities News)
Dongfanghong No. 1 satellite was successfully launched, and he was proud!
Sun Jiadong summed up his career this way: 7 years learning to fly, 9 years building missiles, and 50 years launching satellites. When it comes to several key life choices, he summed it up in one sentence, which is "If the country needs it, I will do it."
On the eve of studying in the Soviet Union in 1951, Sun Jiadong was a Russian translator for the Air Force at that time
In 1957, Sun Jiadong, who was studying in the Soviet Union, listened to Chairperson Mao’s famous words in the auditorium of Moscow University: "The world is yours and ours, but in the final analysis it is yours. You young people are full of vitality and prosperity, like the sun at eight or nine in the morning, and hope rests on you."
When Chairperson Mao spoke for the first time, and Sun Jiadong heard it for the first time, the blood of the young people boiled in an instant. He said, "At that time, he made up his mind to do whatever the country needs you to do."
In 1967, Qian Xuesen personally appointed the 38-year-old Sun Jiadong as the technical director of the "Dongfanghong No. 1". After nine years of missile research, he began to "turn", thus starting the satellite business for his life.
On April 24, 1970, our country’s first man-made earth satellite "Dongfanghong No. 1" was successfully launched, and our country became the fifth country in the world to be able to launch man-made satellites. Sun Jiadong bluntly said that the biggest feeling of the successful launch of "Dongfanghong No. 1" is "proud".
On April 24, 1970, our country’s first artificial earth satellite "Dongfanghong No. 1" was successfully launched.
Sun Jiadong: "After the announcement, we immediately ran to Tiananmen Square, but after we arrived, we couldn’t get in. The crowds were celebrating, and it was a sense of accomplishment. Excited! I’m not a literary person, so I can’t describe it. "
Sun Jiadong, who is 90 years old this year, has personally participated in and witnessed the whole process of China’s aerospace industry from "a blank sheet of paper" to becoming a space power. It was once estimated that the satellites launched under Sun Jiadong’s leadership accounted for one-third of the first 100 satellites launched by China’s aerospace industry. This aircraft has long been integrated with Sun Jiadong’s life experience.

He is the youngest "two bombs and one star" father and the oldest chief designer of satellite engineering. In 2004, our country officially launched the lunar exploration project, and Sun Jiadong, who is 75 years old, once again took up the role of chief designer of the project. Many people do not understand why Sun Jiadong, who has already achieved success, still accepts this risky job. If he fails, his brilliant aerospace career may be overshadowed. Sun Jiadong still said "If the country needs it, I will do it."
Chang’e-1 successfully hit the moon
In 2007, when the signal of the "Chang’e-1" satellite’s successful orbit around the moon was sent back to the command center, people cheered, hugged, and shook hands to celebrate, but Sun Jiadong walked to a secluded corner alone, turned around, pulled out a handkerchief, and wiped the tears from the corners of his eyes.
Sun Jiadong: "I am so excited that I was born in the hot land of China, and I am fortunate to be able to engage in the development of the aerospace industry. This sense of achievement is truly something that I will never forget in my life. So some people asked me, you have built so many satellites, which one do you feel most excited about? I told them that it is difficult to distinguish, and every time there is something difficult to do. "

Sun Jiadong is left-handed and learned to write with his right hand for school. When he was young, he had the skill of playing table tennis with both arches. At work, he also has a set of tricks of "reverse thinking", often with unexpected and impressive ideas and ideas. Ouyang Ziyuan, an academician of the Chinese Academy of Sciences and the first chief scientist of China’s lunar exploration project, commented that "Mr. Sun is a’master ‘who is good at simplifying complex problems."

The youngest "two bombs and one star" father: Honor goes to the collective
In 2009, on his 80th birthday, Sun Jiadong received a letter signed by 98-year-old Qian Xuesen. In the letter, Qian Xuesen said, "You are a young man whom I admired very much. I heard that you are celebrating your 80th birthday this year. I would like to express my heartfelt congratulations to you! You are an outstanding scientist who grew up in the development of China’s aerospace industry and a witness to China’s aerospace industry…"

The vast universe adds another ＂China star＂, let us remember this group of lovely Shanghai astronauts when looking at the starry sky
From today, there is another Chinese satellite in the vast space. In the early morning of November 15, the fourth star of our country’s second-generation polar-orbiting meteorological satellite Fengyun-3 was successfully launched in Taiyuan. And this star, like the other 15 Fengyun meteorological satellites launched by our country, embodies the glory and dream of Shanghai astronauts.
?
Compared with its three "older brothers", Fengyun-3D satellite can be said to have undergone a reborn change. A variety of payloads have been upgraded, and infrared hyperspectral atmospheric detectors, hyperspectral greenhouse gas monitors, and wide-angle aurora imagers have been added, thus gradually meeting the growing new needs of atmospheric detection accuracy, greenhouse gas monitoring capabilities, and comprehensive space environment detection capabilities in the meteorological field. At the Shanghai Academy of Aerospace Technology, the reporter heard the story behind this brand new "China Star".
?
Busy as if obsessed
The Fengyun-3 D-star is loaded with a total of 10 payloads. Compared with the C-star, the D-star has added 4 payloads, and there are 2 that have improved performance and upgraded. Many people think that the Fengyun-3 D-star is a mature model, but the indicator of the 6 new payloads is to reach the international advanced level. The technical status is complex and the development progress is extremely tight.
?
"The high-precision 250-meter split window of the medium-resolution spectral imager is the first in the world, the signal-to-noise ratio of the hyperspectral greenhouse gas monitor in the same spectral range is twice as high as that of GOSAT, the infrared hyperspectral atmospheric detector is consistent with the CrIS index, and the wide-angle aurora imager and ionospheric photometer are both developed for the first time in our country…" Li Yefei, the general director of Fengyun No. 3, used a series of first conveys the extraordinary "origin" of the D star.
?
The six new loads all start from the plan, go through the initial prototype development, and then go through the normal development. The determination of each technical status has to go through countless technical coordination. In the project implementation stage, each load has to sign the interface data sheet, and each load has mandatory inspection points, calibration tests, and ring mold tests.
?
"Sometimes it’s like being obsessed with something all day long. If you say you go to work overtime, you go to work overtime, and if you say you go to work at home, you leave. We really don’t understand." Zhao Qichang, the chief designer of Fengyun No. 3 D star payload, missed the first enrollment of his three-year-old son while working overtime. Faced with his family’s complaints, he can only make up for his "sins" by doing more housework and smiling more.
?
It cannot be looked down upon abroad
With so many new payloads facing such a short development cycle, the progress of the whole satellite is facing challenges, and the progress of the infrared hyperspectral atmospheric detector and the medium resolution spectral imager is particularly tight. "In the first half of 2015, we had to go to the payload unit every day to follow the production, and over time, this batch of designers and the payload unit designers also established a special friendship." Zhao Qichang recalled this period of time deeply.
?
The biggest feature of the Fengyun-3 D satellite data is the global broadcast. Scientists in the global meteorological field are using the Fengyun-3 data, and any problems will be exposed in front of people all over the world. Therefore, the user’s product quality and data quality requirements for the D satellite can be described as "abnormal", from data preprocessing to data application are unmatched by other satellite users, which requires the team to also have data processing capabilities and cannot be underestimated by foreign countries.
?
The Shanghai Aerospace Technology Team started from the original code of the data to analyze, calculate the sensitivity, signal to noise ratio, calibration accuracy, stability, linearity of the instrument, etc., and compare, discuss, negotiate, and finally agree with the user and the load undertaking unit. Users also often praise the Fengyun team as a generalist, not only understanding machines, heat, light, electricity, magnetism, and mechanisms, but also data processing, which is really amazing. However, these are all completed under the condition that the Fengyun team is understaffed. With such a limited number of people, it is really not easy to be both "father" and "mother". But when the satellite is operating stably in orbit, the payload data plays a role in the national economy and people’s livelihood, and international colleagues talk about the evaluation of Fengyun-3’s significant contribution to the world’s numerical weather forecasting, all the ups and downs in the process are nothing.

Overcoming micro-vibration difficulties
Fengyun-3 D satellite is loaded with more than ten loads and more than ten moving parts at the same time. The abnormally complex vibration environment leads to an abnormally prominent contradiction in the dynamic compatibility of the star. If you don’t pay attention, the wish of one-star multi-function will not only not be realized, but multiple loads will interfere with each other. In particular, the loaded interferometric infrared hyperspectral detector is the first application on our country’s low-orbit remote sensing satellite. It has the advantages of high spatial resolution and high spectral resolution. Even small vibrations greatly reduce its performance.
?
"In order to solve the dynamic compatibility problem of multi-load coexistence, provide an ultra-quiet working environment for sensitive load detectors, and improve the accuracy of infrared hyperspectral load detection, we developed a micro-vibration monitoring and suppression system, and applied the’liquid damping vibration isolation ‘technology on domestic remote sensing satellites for the first time to achieve resonant peak and high-frequency vibration suppression." Liu Xingtian, the general development unit of Fengyun Satellite, Shanghai Aerospace 509 Institute, is also a direct participant in the research of micro-vibration monitoring and suppression technology, and has a fresh memory of the process of micro-vibration research.
?
After the research and demonstration of the on-board dynamic spectrum characteristics, the potential mutual interference between the loads was effectively avoided. At the same time, the development of the relaxed "liquid damping vibration isolation" technology can not only effectively control the magnification at the resonance peak, but also attenuate the high-frequency vibration by more than 90%, overcoming the technical problems of traditional passive vibration reduction. At the same time, the research team repeatedly carried out a series of comparison tests, parameter adjustment one by one, and test verification one by one, finally ensuring the harmonious coexistence of multiple loads in orbit and ensuring the imaging performance of the satellite.
?
As a new generation polar-orbiting meteorological satellite in our country, since the launch of Fengyun-3 in 2008, its satellite remote sensing data has provided an important basis for national and local government decision-making. It has played an important role in the meteorological service guarantee of major events such as the "Belt and Road Initiative" International Cooperation Summit Forum, the 13th National Games, the 9th BRICS Leaders’ Meeting, and the 19th National Congress of the Communist Party of China.
