Shared office is sought after, and there are huge business opportunities to help office buildings "destock"

  Xinhua News Agency, Chengdu, November 6 (Yang Wenhao, Hu Xu) Shared office is booming under the wave of sharing economy and double innovation. Many shared office enterprises, including SOHO China, have recently set their sights on Chengdu. With a large number of projects landing one after another, the long-term surplus office market in Chengdu has also ushered in a "warm winter".

  WORK+ joint office space located in Tianfu New Valley, Chengdu High-tech Zone, has become one of the hottest shared office projects in Chengdu at present because of cutting-edge and fashionable decoration design and housekeeper-style intimate service. Its two-story space of nearly 8,000 square meters provides more than 800 workstations, which have served more than 50 small and micro enterprises.

  WORK+ is just a microcosm of shared office being sought after in Chengdu. In recent years, Chengdu’s "double innovation" policy has been further promoted, entrepreneurial groups have been growing, and a large number of small and micro enterprises have emerged rapidly. Start-up companies have small teams and insufficient funds, and the shared office with relatively high cost performance has become their first choice.

  The increase in demand immediately leads to the expansion of supply. Many well-known shared office service providers, such as Dream Plus, Chivalrous Island, Sugar Cube Town and Walnut, have settled in various office buildings in Chengdu. The latest entrant is SOHO 3Q shared office project under SOHO China.

  Pan Shiyi, chairman of SOHO China, believes that from the perspective of market acceptance, Chengdu’s main population has been on the same starting line as first-tier cities, and there are huge business opportunities for sharing office.

  According to the data released by Colliers International, a real estate service company, the vacancy rate of Chengdu office market has remained above 30% for a long time due to long-term oversupply. In the third quarter of this year, although two new projects brought a huge supply of nearly 100,000 square meters, the average vacancy rate increased slightly by only 0.1% from the previous month.

  In this regard, Colliers International reported that with the continuous optimization of the economic and investment environment, the upgrading of industrial structure and the expansion of the consumer market in Chengdu, a large number of domestic and foreign enterprises have expanded here, especially the rapid development of science and technology and joint office industries, which has led to a significant increase in the cases of bulk leasing and rent expansion in the Grade A office market.

People’s leaders | be young friends

On the eve of the May 4th Youth Day in 2022, the Supreme Leader visited China Renmin University.

There are two old photos in the quiet exhibition hall of the history exhibition of the National People’s Congress: one is a photo of the supreme leader and college students; The other photo was taken in Zhengding county government guest house, where the supreme leader and college students sat on the bed and had a long talk.

On July 29th, 1984, the Supreme Leader had a discussion with members of the Summer Social Practice Group of China Renmin University in Zhengding County Government Hostel.

The photo records a past event that happened in the summer of 1984 — — The summer social practice mission of China Renmin University went to Zhengding, Hebei Province for investigation, and the supreme leader of Zhengding County Party Committee made a special trip to visit college students by bike.In Zhengding county government guest house dormitory, the supreme leaderTalk with you and share your experience in grass-roots work for two hours.

From the local to the central government, youth has always been the concern of the supreme leader.

Go deep into the youth, "become one with the vast number of young people" and "be a youth friend, not a youth ‘ Officer ’ " "Be the bosom friend of young friends" … … This is what the supreme leader often says and what he does.

Supreme leaders often go among young people and communicate with them on an equal and cordial basis.

On January 17, 2019, the Supreme Leader had a cordial exchange with teachers and students at the State Key Laboratory of Elemental Organic Chemistry of Nankai University in Tianjin.

On January 17, 2019, the Supreme Leader had a cordial exchange with teachers and students at the State Key Laboratory of Elemental Organic Chemistry of Nankai University in Tianjin.

In 2009, he came to Tianjin University to visit the students who stayed in school during the holiday, and said humorously, "I would like to talk with our classmates ‘ Talk big ’ " ; At a symposium in 2015, he used his personal experience as an example to persuade young people not to stay up all night. "There is passion inside, but we should take it easy outside"; In 2018, he shared his reading experience with his classmates in Peking University: "In the process of reading, through continuous re-examination, we can achieve the negation of negation, review the past and learn new things." "This conclusion drawn through our own thinking and understanding will be firm" … …

The supreme leader is also a pen pal of many young people. One reply after another, the paper is short and affectionate.

"Between the lines, I feel your determination and confidence to strive for the Chinese dream of realizing the great rejuvenation of the Chinese nation." All the students in the 2009 undergraduate league branch of Peking University Institute of Archaeology and Culture read the understanding and recognition from the reply from the supreme leader.

"The peasants have the truest feelings about your efforts and contributions. I have read a lot of materials reflecting the deeds of college student village officials and am happy for your progress and achievements." Zhang Guangxiu, a university student village official, felt affirmation and encouragement from the reply from the Supreme Leader.

"Strive to be a builder of the western region who can be useful and shoulder heavy responsibilities. I support this life choice you have made." The graduates of Karamay Campus of China Shiyou University (Beijing) received recognition and support from the top leader’s reply.

… … … …

"There is no shelf of great leaders at all, and there is no mandarin or cliché. Instead, they communicate with us like big friends." "It gives people the feeling that they are so easy-going and kind" and "very approachable" … … This is the impression left by the supreme leader on many young people.

On May 28th, 2023, the resident college students of Xifangezhuang Village Science and Technology Academy in Yukou Town, Pinggu District, Beijing measured the hardness of tomato fruit in Jingwa Greenhouse Horticultural Demonstration Park in Yukou Town, Pinggu District.

Youth is in the initial stage of life, and it is inevitable that they will be confused and confused during their growth. In the eyes of young people, the supreme leader is a "senior" and a "big friend". He always guides young people to take every step of life with words that they can understand and listen to.

He used the metaphor of "kneading dough" to explain the process of entering society to young people in a simple way: "When flour is kneaded with water and then kneaded, it is easy to disperse. But if you keep rubbing it for thousands of times, it will never spread out again. " The supreme leader used this vivid metaphor to tell young people that only when a person grows up under various tests can he really withstand the pressure of life.

Talking about learning, the Supreme Leader encourages young people to "draw knowledge like a sponge" and practice excellent skills; Speaking of physical fitness, he introduced his sports hobbies and encouraged young people to do well in their studies and make their bodies great; On self-cultivation, he exhorted young people to "button up their lives from the beginning" and cultivate a correct value orientation … … Good words are the mutual understanding between friends, and also the advice and encouragement from the predecessors to the younger generation.

一位曾在1990年和时任福州市委书记最高领袖座谈过的北大学生表示:“我们觉得习书记非常懂得青年人的所思所想。”

“支教多长时间了?”“现在工资水平和县城或者其他地方比怎么样?”“多长时间能回一次家?”……2019年,重庆华溪村中益乡小学操场上,最高领袖细致地问询。听一位乡村教师说上完大学后就回到母校担任老师,已经工作了17个年头,最高领袖为她点赞:“太好了!”“你们做的工作很有意义。”

2023年全国两会期间,“80后”代表魏巧向最高领袖讲述了新时代“新农人”的故事:“我们现在种植了2万多亩水稻,亩产达1100斤……有效带动了周边农民致富。”最高领袖赞誉道:“像魏巧这样的同志到农村去,很好!”

In the Hengqin Campus of the University of Macau, I saw that all the students were full of youthful vigor. The supreme leader quoted two lyrics to talk about patriotic complex: one was "Build our new Great Wall with our flesh and blood" in the national anthem, and the other was "But they took my body away, and you still keep my inner soul" in the Song of Seven Children.

"I can always hear new ideas and be touched." The supreme leader’s personal feelings infected every young person present.

Youth dreams, home and country. Under the care of the supreme leader, every seed of youth has accumulated the power of growth.

"The young people in China in the new era are good and worthy of great responsibility!" "Where is the future? The future is here for you. " The supreme leader’s entrustment to young friends is also the expectation for the future of the motherland: "This loong must have a backbone and hold on, so that she can take off higher."

Based on the current situation, building a well-off society in an all-round way will provide more abundant material conditions and broader application prospects for scientific and technological innovation; Facing the future, scientific and technological innovation will provide stronger development impetus and open up new development space for the next step of building a socialist modern power.

Make more efforts to make the computing industry bigger and stronger, compete for "smart computing" and lead the industrial transformation.

CCTV News:This month, the Ministry of Industry and Information Technology and other six departments jointly issued the "Action Plan for High-quality Development of Computing Infrastructure", which clearly stated that the comprehensive supply capacity of computing power will be steadily improved. What is the current development of China’s computing power industry? What are the key points in the next step? Come and see the reporter’s report.

Headquarters CCTV reporter Ning Kun:Now, such a holographic cartoon character beside me can have a simple question-and-answer conversation with you like a personal assistant, and these large models also need a lot of computing resources in training. Hello, what other fields can computing power be used in?

The image of virtual "number wise men" is orange;In addition to intelligent transportation, smart cities, intelligent manufacturing, intelligent mines, high-definition video, virtual reality, augmented reality and other fields, we can also apply computing power to more fields.

The intelligent computing center used in artificial intelligence training has also become the key direction for all parties to build computing infrastructure. Compared with traditional data centers, intelligent computing centers have higher requirements for computing chips, software and high-speed networks. In Zhangjiakou, Hebei Province, a large-scale intelligent computing center was officially put into operation, and finally it can reach 120 billion floating-point operations per second.

Wang Chaoyang, General Manager of R&D Division of Alibaba Cloud Data Center:Take the short-term and medium-term weather forecast model we recently cooperated with our customers as an example. It takes several hours to calculate in the traditional way, but it can be compressed to less than 3 seconds by using intelligent calculation.

According to industry insiders, the demand for intelligent computing in frontier fields such as large-scale model training, remote sensing detection, life sciences and autonomous driving is growing rapidly.

According to the recently issued "Action Plan" goal, by 2025, the proportion of intelligent computing power in China will further increase from the current 20% to 35%, and the growth rate will be faster than the average growth rate. According to incomplete statistics, at present, there are more than 30 cities in China that are building or preparing to build intelligent computing centers.

Zhao Ce, Deputy Director of the Information and Communication Development Department of the Ministry of Industry and Information Technology:Strengthen the monitoring of data center occupancy rate, optimize the layout of computing infrastructure in the country, especially highlight the deployment of intelligent computing power, and support the development of key industries and key fields such as artificial intelligence.

The integration of "East Counting and West Counting" and cost reduction calculation networks has become a trend

According to the latest data, the number of standard racks in use in China’s data centers exceeds 7.6 million, ranking second in the world in terms of total computing power. How to allocate and use the rapidly growing computing power resources more reasonably and efficiently? Continue to read the report.

In a company specializing in film and television production in Zhejiang, there are now more than 30 films that need to be rendered in the later stage every year. This rendering process needs a lot of computing resources, which used to be done by local servers, but because of the shortage of resources, it will also encounter problems such as long rendering cycle or high cost.

Zhang Shiyu, visual effects director of a cultural media company in Zhejiang:In the past, rendering was always done locally. (Now) Through the "computing brain", the computing power of the west (region) was called, which greatly shortened the rendering cycle and saved the overall cost by more than 10%.

The so-called "computing brain" refers to a scheduling system that can cover a large number of computing resources in the country to dynamically allocate computing power in different regions in real time to complete tasks.

Sun Shaoling, Deputy General Manager of China Mobile Cloud Capability Center:Integrating computing network resources all over the country into a supercomputer, so our network is actually more like the bus inside the computer, which requires very high network delay and bandwidth.

Experts said that in the process of future convergence and development of computing networks, it is necessary to fully consider the rational distribution of computing power supply and demand between the eastern and western regions, and at the same time continuously improve the data transmission capacity of the network. According to the recently issued "Action Plan" goal, in terms of carrying capacity, by 2025, the national hub node data center clusters will basically realize direct network transmission not higher than 1.5 times the theoretical delay, and the coverage rate of optical transmission networks in key application sites will reach 80%.

Wang Zhiqin, Vice President of China Information and Communication Research Institute:According to the setting of data center, supercomputing center and intelligent computing center, it may play a good role in the traction of some new types of optical communication products with higher speed (bandwidth), including 400G (Gigabit) and 800G (Gigabit).

In this transaction, a number of well-known institutions provided consulting services for both parties to ensure the smooth progress of cooperation.

Evaluation of old graphics card GTS250: Looking at the progress of 65/40/28 nm

  [PConline evaluation]Recently, the graphics card industry is full of news about GTX780, which is fascinating, but it is not something that ordinary users can consider. Let’s look back at the actual products. A series of old graphics card tests, we have been reflected by many netizens, this time we should test GTS250 at the request of netizens.

  The graphics card is called "GTS250", and familiar netizens know that this is the "mysterious" power of NVIDIA, which has changed from 9800GTX+. The specifications and parameters are just like 9800GTX+, and there is a significant change in memory. At that time, the core of NVIDIA G92 was old.

GTS250 evaluation

  After years of baptism, the high-end old cards many years ago are no different from the performance of general mainstream graphics cards. This time, we use another test method to see the performance differences of GTS250, GTS450 and GTX650. These three graphics cards use three different architectures and three different technologies, which also represent three different eras.

Comparison of three products with "5":

Graphics card comparison

  Although it also had a "5", GTS250 was launched in the mid-to high-end market of 999 yuan at that time, pushing HD4850. Similarly, GTS450 is also used as the mid-end market of 899 yuan, and HD6770/6750 is suppressed within 1,000 yuan. By GTX650, the market it faces has become the mainstream level, and this "5" has been devalued more and more.

  GTS250 uses the "G92" core which has entered dusk at that time (it has been used for three generations). Although the technology is a little old, its performance is still a bit worth seeing. When it comes to GTS450, using the mature Fermi architecture, the most brilliant period is not that it can suppress HD6750, but that the GTX650 introduced later is expensive, which makes GTS450 have a short spring. GTX650 is currently using NVIDIA’s most advanced Kepler architecture, with excellent energy consumption ratio, but the price is still slightly higher.

  If you want to know the positioning of the graphics card at that time, then it is most direct to look at the memory width. Due to the high cost of GDDR5 at that time, GTS250 still used GDDR3 video memory, with 256bit width and 64 texture units, which could not hide its high positioning at that time. As for the current GTX650, except for more stream processors, other parameters are relatively simple.

  This time, we received three graphics cards from Mingxin, which were used to test the performance and power consumption differences of these three graphics cards: GTS250, GTS450 and GTX650. These three graphics cards use the three-generation architecture of Trass, Fermi and Kepler respectively, and the three processes of 65 nm, 40 nm and 28 nm are also models with the word "5" in the middle. What will happen? We’ll leave right away.

  In order to unify the performance of the platform, we use the high-end 3770K platform to ensure that it does not cause system bottleneck, which is more convenient for the performance of the graphics card. We use the latest driver 310.14 beta at present, and add a new game "Subway: The Last Dawn". Of course, the games all choose DX9 or DX10 running mode.

Theoretical test scores:

  Because some graphics cards don’t support DX11, we tested 3DMark Vantage and the new 3DMark, and the results are for reference only.

  Test summary:Judging from the test results, the progress of the three graphics cards is relatively balanced. The score displayed by 3DMark Vantage, GTS450 is twice as high as GTS250, regardless of its accuracy, at least the detected result mainly depends on the graphics card. As for the Cloud Gate scenario of the new 3DMark, it is more about the performance of the platform.

  In order to make it easier for everyone to read, we have simplified the description of the game and compiled a variety of games into a big chart to make the comparison of the results more intuitive.

On the Significance of Game Frame Number (FPS)

  The number of game frames is a standard to reflect whether the game runs smoothly, which can be classified in most cases.No playability:The number of frames is less than 30FPS;;Acceptable:30-50 frames;Smooth operation:50-60 frames;Perfect operation:The number of frames is greater than or equal to 60. That is to say, under normal circumstances, the number of frames is greater than 60, which is of little significance. At this time, you can increase the quality of the game to get more visual effects.

Graphics card test

  Now many new games use DX11 interface, and we adjust most of them to DX9 or DX10 mode. From the test of the game, GTS250 is not as bad as 3DMark Vantage shows. At least GTS450 is not twice ahead of GTS250, and the performance of the three in the game is more like the performance of the new 3DMark.

  In addition, we also see that it is not impossible for GTS250 to play mainstream games in full HD resolution, but there is basically no enjoyment in image quality special effects.

Summary of evaluation results
GeForce GTS450 PK GTS250  +19% GeForce GTX650 PK GTS450  +21% GeForce GTX650 PK GTS250 +44%

  To sum up the achievements of the three graphics cards, the performance improvement of each generation is about 20%. We can guess that GTX750 may be 120% of GTX650, and perhaps GTX750 is a GTX650Ti vest (see GTX770 vest GTX680).

Platform power consumption test:

  Before the test, it should be noted that since the independent power consumption of the graphics card cannot be tested, all the power consumption scores in this round of test are the power consumption of the whole machine, and the power consumption tester is used for testing during the test. During the test, we run Tomb Raider 9 benchmark to test the average power consumption of the platform.

Platform power consumption

  Test summary:The technology is more and more sophisticated, the architecture is more and more advanced, and the power consumption is lower and lower. In the previous GTS250, the power consumption of the platform was 238W, while the GTS450 with stronger performance was 225 W. In Kepler’s generation, the power consumption was as low as 158W W.

  Compared with GTS250, GTS450′ s energy consumption progress is mainly achieved through the improvement of technology, and GTX650′ s performance is like this. In addition to the improvement of technology, streamlining general-purpose computing is also one of the means.

  PConline ladder diagram description:From the test, it can be seen that the performance difference between GeFoece GTS250 and GTS450 is about 20%, which is smaller than that of GTS450 and GT640. We define that GTS250 has better performance than GT640, as shown above in the ladder diagram.

● What is the value of ●GTS250?

  Looking back at GTS250, the listing price at that time was $149, which was close to 1,000 yuan at that time. What now? Although there are no new graphics cards, let’s go to the second-hand forum to see the current market.

Second hand price
The picture is intercepted in this forum (the value is also the best in 200 yuan)

  At present, GTS250 is probably worth 250 yuan. In four years, the value has shrunk to 1/4 of that at that time. Once again, we must feel the fall in price speed of IT products. With the performance of GTS250, you can still enjoy the game now. The price in 200 yuan is better than buying a GT630.

●GTS250 upgrade or purchase suggestion.

  At that time, with the GTS250 graphics card, most platforms used Xiaolong quad-core, Kourou E8400, or Kourou quad-core platforms. Compared with the current CPU performance, it is not bad, probably reaching the level of X4 740, and the performance can also be exerted with the current mid-range graphics card.

Upgrade suggestion

   For those friends who are about to retire from GTS250, we suggest to consider GTX650Ti, whose performance is far superior to that of GTS250, and its power consumption is lower than that of GTS250, and its energy consumption ratio is good. As for the friends who want to change to a new platform, according to the consumption level, they should buy the I5 grade at present, and of course they will match the GTX660Ti.

  The improvement of GPU technology and the update of architecture can improve the performance and power consumption of graphics cards, which will be reduced to 1/4 in four years. After four years, is HD7990 worth 2K? In the next issue, we will test the previous God cards, such as GTX295 and HD4870x2, and now the performance is equivalent to what price of graphics cards.

Archaeological research achievements in Xizang | Qiege site is expected to uncover the history of North China people’s migration into Tibet

CCTV News:Today (January 13th) morning, National Cultural Heritage Administration held a report meeting on archaeological discoveries in Xizang, and reported four major archaeological discoveries in Xizang, including Qiege site, Mabulu site, Gebuseru site and Dangxiong cemetery. Among them, Qiege site is a rare site of early prehistoric human activities with clear stratigraphic accumulation in the hinterland of Qinghai-Tibet Plateau, which fills the gap between the hinterland of Qinghai-Tibet Plateau and 8,000 years ago. The blank of prehistoric archaeological culture in 10000 years, and more importantly, a dense distribution area of stone products was found in the site, which is expected to gradually uncover the long history of North China people migrating into Tibet about 10 thousand years ago.

This is a fine stone core, less than two centimeters, with angular surface and "cut marks", which is the effect of pressing and "cutting" with a special tool. This is the small part that has been "cut". It is called a fine stone leaf by archaeologists. Its edge is as sharp as a blade, and its size is only a few millimeters to a few centimeters. It was used by people who cut heat on the Qinghai-Tibet Plateau about 10,000 years ago. It is extremely difficult to "cut" a stone knife. Small fine stone cores and leaves condense the great wisdom of ancient humans on the Qinghai-Tibet Plateau in the Paleolithic Age.

These stone tools, which surprised archaeologists repeatedly, were unearthed at the Qiege site in Ali, Xizang. According to reports, Paleolithic remains such as fine stone leaves and fine stone cores are often found on the surface of the Qinghai-Tibet Plateau. However, the remains collected on the surface can’t determine the primary strata and dating, and when human activities appeared on the Qinghai-Tibet Plateau has been an important issue for half a century. In 2011, an archaeological team led by Zhang Xiaoling, an associate researcher at the Institute of Vertebrate Paleontology, Chinese Academy of Sciences, began to investigate in Xizang. In 2012, several potential sites were found on the banks of Shiquan River in Gaer County, Ali region. After further investigation and trial excavation, it was determined that Qiege site was of great research value. August & mdash; 2020; In September, the site was officially excavated, and more than 5,000 cultural relics were unearthed in an area of nearly 70 square meters. A long-lost human history on the Qinghai-Tibet Plateau in the Paleolithic Age slowly emerged.

Archaeologists said that nearly 30,000 years ago, the remains of fine stone leaves first appeared in North China, and reached a prosperous period about 15,000 years ago. However, the fine stone leaves and other cultural relics found in Qiege site in Xizang are highly similar to the remains in North China, and the time is relatively late. In which region did ancient humans migrate to the Qinghai-Tibet Plateau? The answer has also become clear.

According to reports, in the whole Paleolithic period, that is, 99% of human history, human beings often migrated and moved because of changes in food and resources. Previously, the archaeological team of Zhang Xiaoling, Institute of Vertebrate Paleontology, Chinese Academy of Sciences, discovered the track of human activities 40,000 years ago at the site of Naqunia in Xizang. The discovery of Qiege site fills a historical gap in the process of human survival and adaptation and the formation of Tibetan population in Qinghai-Tibet Plateau after 40,000 years.

Gao Xing, a researcher at the Institute of Vertebrate Paleontology, Chinese Academy of Sciences:The ancient people, whether their remains or their cultural remains, may not all be preserved, so writing the history of human beings with archaeological materials can only be intermittent. I am afraid this puzzle will never be put together completely, but its big outline will be established.

The Ministry of Education issued the early warning information of the 2022 college entrance examination to remind the majority of candidates to be vigilant and beware of being deceived.

  College entrance examination is a big test in the life of college students, which is related to the vital interests of candidates and has attracted much attention from the society. With the approach of the college entrance examination in 2022, the majority of candidates have entered the final sprint stage, and some lawless elements have also used the college entrance examination to spread false information, create anxiety, cheat and even induce candidates to cheat in the exam. To this end, the Ministry of Education, in conjunction with the Central Network Information Office, the Ministry of Public Security and other departments, combined with some typical cases in recent years, solemnly reminded the majority of candidates and parents to be vigilant and beware of being deceived.

  1. Organizing cheating in the college entrance examination is a serious violation of the law.

  During the college entrance examination, criminals often post "exam-helping" information online, claiming that they can provide exam questions and answers for candidates. As everyone knows, it is a serious crime to organize candidates to cheat in national education examinations such as the college entrance examination, provide candidates with test questions and answers, and sell and use wireless cheating equipment.

  [Case] During the college entrance examination in 2019, He Mohao, a college student, posted an advertisement for "Assisting Exam" on the Internet, and 12 candidates from Guangdong, Shandong and Guizhou paid the "registration fee" to him. He Mohao contacted college students Nie Mouwu and Peng Molin (He Mohao’s classmate) on the Internet, and the three worked together. He Mohao was responsible for contacting and passing the test questions and solving the answers, Nie Mouwu was responsible for solving the problems, and Peng Molin was responsible for sorting out the test questions, cheating for 12 candidates during the college entrance examination. On June 8, the police acted immediately after receiving the clue and arrested He Mohao, Nie Mouwu and Peng Molin on the spot. Three people were sentenced to two to three years and six months in prison for cheating in organizing exams.

  【 Regulations 】 The Criminal Law of People’s Republic of China (PRC) clearly stipulates that it is illegal to organize cheating, sell or use wireless cheating equipment, provide test questions and answers to candidates, or let others take the exam instead of themselves in the national examination prescribed by law. The Interpretation of the Supreme People’s Court and the Supreme People’s Procuratorate on Several Issues Concerning the Application of Laws in Handling Criminal Cases such as Cheating in Organizing Examinations makes it clear that those who cheat in national education examinations such as college entrance examinations and postgraduate examinations will be directly identified as "serious" acts, and will be sentenced to fixed-term imprisonment of not less than three years but not more than seven years and fined.

  [Reminder] In recent years, local public security organs, together with the education departments, have continued to maintain a high-pressure crackdown on all kinds of illegal and criminal activities involving exams, with "zero tolerance". The majority of candidates must enhance their legal awareness, refuse to cheat in exams, and don’t try the law.

  Second, taking the test is not a shortcut, but a "desperate situation"

  In order to get their children into an ideal university, some parents try their best to find a "way" for their children and even find a "gunman" to take the exam for their children. As a result, people and money are empty, and the consequences are very serious.

  [Case] In order to let his nephew Xiao Chen, who has poor academic performance, be admitted to the undergraduate course, Li and Xiao Chen’s mother discussed and decided to spend money to find someone to take the exam for Xiao Chen, and promised to give 50,000 yuan for being admitted to "one book". In the end, Liu, a graduate student in a school, promised to take the test for Xiao Chen. Results On the day of the college entrance examination in 2019, Liu was discovered by invigilators on the spot. The police immediately filed an investigation, and the people involved arrived in the case one after another. Li organized candidates to cheat, which constituted the crime of cheating in organizing exams. He was sentenced to three years in prison and fined 30,000 yuan. "Gunner" Liu took the test instead of others, which constituted the crime of taking the test instead; Parents of students who let others take the exam instead of their children also constitute the crime of taking the exam instead. They were sentenced to five months’ criminal detention and fined 4,000 yuan to 10,000 yuan respectively.

  【 Regulations 】 The Criminal Law of People’s Republic of China (PRC) clearly stipulates that it is illegal to "organize cheating" or "substitute others or let others take the exam instead of themselves" in the national examination prescribed by law. Moreover, the crime of substituting for examination is a typical opposite crime. The criminal law punishes both the examinee and the gunman, and the conviction and legal punishment are the same.

  [Reminder] Parents who help their children cheat are not loving their children, but harming them. In the end, they will have to bear legal responsibility. Liu, a graduate student, acts as ‘ for tens of thousands of yuan of substitute exam fees; Gunner ’ , ruined his bright future. The majority of candidates and parents should fully understand the harm and legal consequences of taking the test, and take the test in good faith, otherwise they will suffer the consequences.

  Third, I am lucky to bring my mobile phone, and cheating in the exam will ruin my future.

  Nowadays, the use of smart phones is very common, and some candidates often use smart phones to search questions, translate and other functions to assist learning and improve efficiency. However, if you cheat with your mobile phone in the exam, you have miscalculated your abacus, and you are smarter than you are.

  [Case] During the college entrance examination in 2021, a candidate illegally carried a mobile phone to avoid the entrance security check and brought the mobile phone into the examination room. During the examination, the student used his mobile phone to sneak shots of the test questions and sent them to the off-site for answers, which was seized on the spot. According to the Measures for Handling Violations in National Education Examinations, the student was punished with disqualification, and all his grades were invalid, and he was stopped from taking national education examinations.

  [Regulations] The college entrance examination is a national education examination prescribed by law. The Measures for Handling Violation of National Education Examination clearly stipulates that anyone who uses communication equipment during the examination shall be deemed as cheating in the examination, and his scores in all subjects registered for the examination at that time shall be invalid. The Education Law of the People’s Republic of China clearly stipulates that candidates who carry or use cheating equipment and materials in national education examinations, if the circumstances are serious, shall be ordered by the education administrative department to stop taking the relevant national education examinations for more than one year and less than three years; If it constitutes a violation of public security administration, it shall be punished by the public security organ according to law; If a crime is constituted, criminal responsibility shall be investigated according to law.

  [Reminder] In order to prevent and crack down on cheating on mobile phones in national education examinations and further strengthen the comprehensive management of the examination environment, in 2022, the Ministry of Education, the Ministry of Public Security and the Ministry of Industry and Information Technology jointly deployed local education, public security, communications, radio management and other departments to take a number of measures to carry out the special treatment of "cracking down on cheating on mobile phones". The majority of candidates must know the law and abide by the law, take the exam in good faith, and don’t take chances, so as not to ruin their future.

  Fourth, look for the official logo and don’t believe "gossip"

  Every year before the exam, there will be a lot of information about the exam on the internet, and all kinds of information are mixed. In order to attract attention, some individuals or training institutions take the opportunity to register "shanzhai" public accounts and spread "gossip" from unofficial sources to seek benefits.

  [Case] The college entrance examination in 2020 was postponed for one month due to the epidemic. From time to time, there are so-called college entrance examination arrangement information from the media on the Internet. For example, there are false news about "the arrangement of the examination room in a city in 2020" from the media, which misleads the public and causes anxiety among candidates and parents. According to the city’s education bureau, the news is false information.

  【 Regulations 】 According to the Regulations on the Administration of Internet User Account Names and the Regulations on the Administration of Internet User Public Account Information Services of the Central Network Information Office, the Internet user account names registered and used by any institution or individual shall not spread rumors, disrupt social order and undermine social stability; Public account producers and operators shall not maliciously counterfeit, counterfeit or embezzle the public accounts of organizations and others to produce and publish information, and shall not fabricate false information, distort the truth and mislead the public. Those who violate laws and regulations will be severely dealt with according to the law.

  [Reminder] In 2022, the Ministry of Education, together with the Internet, the public security department and a number of Internet companies, will continue to carry out the special action of "lighting the official website logo of the authoritative examination enrollment institution" and "cleaning up the public accounts involved in the Internet examination", so that the majority of candidates and parents can timely, comprehensively and accurately understand the college entrance examination information of authoritative institutions and avoid being deceived. When the majority of candidates and parents search for information about the college entrance examination online, please look for the "official" logo of the authority (such as,) and beware of fake accounts or website scams.

  Five, don’t believe false propaganda, beware of being deceived.

  Exam "guaranteed", double promotion, XX days crash, or exclusive "internal resources", "proposition experts" to teach, to ensure "one-time pass" and so on … … Such slogans and enrollment advertisements often appear in the enrollment propaganda of various examination and training institutions, which makes many parents believe it. In fact, there are violations of laws and regulations such as exaggerating propaganda, fictional teachers, price fraud and false advertisements to varying degrees.

  【 Regulations 】 The Advertising Law of People’s Republic of China (PRC) clearly stipulates that advertisements for education and training shall not contain the following contents: (1) Make an express or implied guarantee commitment to entering a higher school, passing an examination, obtaining a degree or a certificate of qualification, or to the effect of education and training; (two) express or implied that the relevant examination institutions or their staff and examination proposition personnel participate in education and training; (3) Using the names or images of scientific research institutions, academic institutions, educational institutions, trade associations, professionals and beneficiaries for recommendation and certification.

  [Reminder] Candidates and parents should not believe in false advertising, which will not only cause property losses, but also delay valuable review time.

  Sixth, online fraud should be identified, and the answer to the college entrance examination cannot be purchased.

  Every year, criminals peddle so-called "college entrance examination questions" and "top secret answers" on online platforms or communication groups, flaunt seductive information such as "extremely high accuracy" and "default refund", and ask users to pay in advance in the name of "advance deposit". Others send viruses to users’ computers or mobile phones in the name of transmitting "sample test papers" to obtain user information.

  [Case] In March, 2021, Huang entered several chat groups through QQ, falsely claiming that he had channels to buy answers to the college entrance examination, and sold the so-called "answers to the college entrance examination papers" to parents and candidates at a price of 15,000 yuan per subject, defrauding more than 10 people in five provinces, including Anhui, Shandong and Hunan, and defrauding more than 100,000 yuan. At present, Huang has been criminally detained by the police according to law, and the case is under further investigation.

  【 Regulations 】 The Criminal Law of People’s Republic of China (PRC) clearly stipulates that it is illegal to "illegally sell or provide questions and answers to others for the purpose of cheating in the national examinations prescribed by law".

  [Reminder] The college entrance examination questions belong to the national top secret materials, and their storage and transportation have extremely strict management measures. The majority of candidates and parents must polish their eyes, distinguish between true and false, and beware of fraud!
