　　Recently, Guangzhou police detected a case of using Trojan horse program to remotely control the camera. Criminals taught themselves to crack the technology and randomly invaded the home camera with simple password settings. According to the police, the man invaded more than 500 sets of surveillance cameras, involving private places such as bridal shops, supermarkets’ dressing rooms and family bedrooms, and some surveillance videos were even sold. "Home cameras are far less secure than imagined?" "Why is there a camera in Shangchao dressing room?" Cameras born for "guarding security" have become a dangerous "eye of the storm". How should citizens’ privacy and personal information be protected? In order to find the answer to the question, the reporter made many visits.

　　Home cameras have become "live devices"?

　　Technical experts: the market is mixed, look for reliable manufacturers.

　　Ms. Zhou, a citizen, told reporters that due to busy work, it is "just needed" to remotely monitor the dynamics of babies and nannies at home. She said that she was very worried about some cases of child abuse by nannies, and her lover was also involved in business. Fortunately, there was camera supervision to ensure the quality of babysitting for nannies. There are not a few citizens who have the same needs as Ms. Zhou. The reporter interviewed a number of consumers randomly and found that the purpose of the public to buy home cameras is to look after children, the elderly and pets remotely and pay attention to family situation. Through offline stores and e-commerce platforms, the reporter learned that there are many kinds of home cameras currently on the market, such as 360-degree panoramic smart cameras, 2K high-definition cameras, 5G dual-frequency cameras, etc., to meet the multi-dimensional needs of consumers as much as possible.

　　Ms. Wu, a citizen who has two cats at home, said that it is very convenient to look after her cat remotely on her mobile phone. At the same time, she also has some vigilance: "Because the camera is installed in the bedroom, for privacy reasons, I will immediately remove it as soon as I get home, so as not to photograph myself." Ms. Wu’s vigilance is not unreasonable. Even in the private space where the guard should be put down, people’s every move may become a "commodity" with a clear price tag and flow into the unknown black industrial chain.

　　The reporter learned that since the birth of smart cameras, some lawless elements have sold cracking tools and tutorials on the Internet platform, and they can crack IP addresses and account passwords by paying only a few hundred yuan, turning cameras used to guard privacy into "live broadcast devices".

　　Mr. Liu, a technical expert who works for a well-known monitoring solution service provider, told reporters that "camera attacks do occur from time to time, and most of them are civilian cameras. Because of the low market entry threshold, the shanzhai manufacturers have not guaranteed the technology accumulation of video security. Secondly, the safety awareness of users in the civilian market is not enough, and the router password and camera password are not changed regularly, and the camera firmware is not upgraded regularly. " Some users think that the problem lies in the camera APP. Mr. Liu pointed out that in the case of a Trojan horse in the mobile phone, the camera APP does have the risk of being stolen, but the main reason for video leakage is the camera side.

　　Fortunately, thanks to the improvement of camera safety technology and industry norms, the frequency of similar cases has been greatly reduced compared with previous years. Mr. Liu said: "Big manufacturers have done a good job in this respect. For example, if they use it for the first time, they will be forced to change their passwords and require the use of passwords with high complexity. Users can also encrypt videos, even if hackers obtain videos, they can’t crack them. In addition, the firewall function of the intelligent router can also scan the cameras in the network, which virtually adds a barrier. At the same time, media reports and police strikes have enhanced public safety awareness and also played a deterrent role. "

　　The reporter noted that the legal issues involved in home cameras can not be ignored. It is understood that some citizens did not inform the nanny of the fact that a camera was installed at home in order to "assess the real working level of the nanny". Is this a move suspected of infringing on the nanny’s privacy? The reporter consulted the director of the Network and E-commerce Law Research Association of Guangdong Law Society and the lawyer of Guangdong Zhuoxin Law Firm. Training advice: "It is best to inform and avoid misunderstanding. Citizens have the right to install cameras in their own homes, but it is inappropriate to install them in private spaces such as the nanny’s bedroom or bathroom. It is reasonable and legitimate to install them in nanny workplaces such as living rooms and kitchens, and it will not infringe on the nanny’s privacy. "

　　Public space cameras "everywhere"?

　　Guangzhou local supermarket: the privacy of people entering and leaving has been protected to the maximum extent.

　　Lin Cong, an Internet practitioner, has always been worried and resistant to electronic products such as surveillance cameras. He said: "Once the loopholes in electronic products are exploited by hackers, the consequences are quite terrible, especially in private places such as hotels, dressing rooms and toilets." At the same time, he asked: "Why do merchants install cameras in private places in public spaces?" Previously, a well-known clothing brand was exploded to install a camera above the fitting room, which has triggered public vigilance and industry reflection.

　　Has the camera been abused in public places? To this end, the reporter visited the local business circle. In a senior commercial building in Zhujiang New Town, a technician told the reporter: "The cameras we installed in indoor public areas are not connected to the internet, and the security is still very high compared with the home networked surveillance cameras." He pointed out that the general monitored materials are only deleted after 7-15 days, and Shangchao will not set up cameras in private spaces. The staff of an office building in Tianhe Business Circle also told the reporter, "The camera we set up at the entrance and exit of the restroom in the public area of the venue only faces the entrance and exit seats, and will not directly capture the people entering and leaving." He said that on the basis of ensuring fire safety, the privacy of people entering and leaving has been protected to the maximum extent.

　　In addition, whether it is a private buyer’s shop or an independent clothing store in a shopping mall, they are more cautious about protecting consumers’ privacy. The person in charge of a chain clothing store located in Tianhe business district said that there is no face recognition camera installed in the store, and there is no camera control near the fitting room. "Our camera angle will only face the entrance and exit of the fitting area." Miss Zhang, the manager of an independent fashion shop, told the reporter: "Although our fitting room is curtain-drawn, it is highly direct to the ceiling without leaving gaps, and it is very safe." She introduced that there are only two cameras in the store, and the control angle is diagonal, one from the door to the innermost, and the other from the innermost to the door.

　　Mr. Liu, a technical expert, said: "At present, public security video surveillance has a complete set of information security specifications." However, it is difficult for industry norms to avoid unscrupulous criminals. Previously, a pinhole camera incident in a fitting room in Shenzhen caused concern. After investigation by the police, the camera was not installed in the store, but a man bought pinhole camera equipment online for "seeking excitement" and installed it in the fitting room. The reporter learned that on some internet platforms, there are even many unscrupulous people who use keywords such as "hotel", "fitting room" and "sneak shot" as marketing gimmicks to sell equipment.

　　Baidu, 360 and other companies have launched an "anti-pinhole camera" APP, claiming to help users find cameras that are not easy to detect. In this regard, Mr. Liu said that although the "pinhole camera" APP can play a role, most of them have limitations. This kind of APP can be divided into two types. One is to use a mobile phone camera to find pinhole cameras. "Only cameras with infrared fill light can be found, but cameras without infrared fill light can’t be photographed clearly in a dim environment." The other is to use the mobile phone APP to scan the cameras in the WLAN network. "But some pinhole cameras are not connected to the network or send out hot signals themselves, or they are not connected to the WLAN network where the mobile phone is located. At this time, the APP does not work."

　　Support:

　　This will not be "live" … …

　　1. Try to buy products from big manufacturers. At present, the safety precautions of large manufacturers are in place, and most of them have participated in the construction of safe cities, and their cameras meet the safety requirements of the Ministry of Public Security.

　　2. Don’t use the default password for the camera, and don’t use the password with strong regularity and low complexity like "12345". Modify the password regularly, upgrade the firmware issued by the manufacturer, and regularly kill viruses by reliable means. It is best to encrypt the video to improve the difficulty of being cracked. Once the camera is found to be abnormal, please turn off the monitoring equipment and call the police in time.

　　3. Don’t use a simple password for router WIFI, because the intrusion of the router will also make the camera more vulnerable to intrusion. It’s best to buy an intelligent router with a firewall to prevent hacker attacks and virus invasion and have a safer network environment.

　　4. When installing a home camera, pay attention to avoid areas that are easy to expose privacy, such as bedrooms and bathrooms, and record the angle of initial installation. Once the actual shooting angle of the camera changes, check the account security immediately and take protective measures.

　　5. Pay more attention in hotels, fitting rooms, bathrooms, escalators, buses, subways and other places. At present, the anti-pinhole camera APP sold in the market can’t completely protect privacy. It is best to pay attention to the articles published by the police from time to time, understand the various forms that pinhole can disguise, and be vigilant.

　　Statement:

　　If it has been "live" … …

　　In the face of invincible cameras, how can we protect our own rights and interests? In this regard, Lian Qing lawyer said that the case detected by Guangzhou police this time is very typical. In recent years, similar cases have appeared in many cities. For example, in 2017, Beijing police successfully detected the first criminal chain in China that spread home camera cracking software online and arrested 24 people involved.

　　She analyzed that this is a criminal case, which is suspected of illegally obtaining computer information system data and illegally controlling computer information systems, and belongs to a type of hacking crime. In addition to computer information security, the behavior involved also violated another object, that is, citizens’ personal information, so this behavior is also suspected of constituting a crime of infringing citizens’ personal information. In addition, because the suspect broke the camera involved in the fitting room and family bedroom and sold the video for profit, it may also constitute the crime of making, copying, publishing, selling and spreading obscene articles for profit.

　　Lian Qing pointed out that this kind of crime is relatively secret, and ordinary people often don’t even know that they are victims. They mainly rely on the power of public power to investigate and severely punish them.

　　She suggested that from a civil point of view, if a citizen’s right to privacy is violated, the perpetrator can be required to stop the infringement, eliminate the obstruction and compensate for the losses according to relevant laws and regulations. "But the difficulty of such cases lies in how to find and locate these infringers or suspects. If citizens find their private videos or photos spread on the Internet, in addition to reporting the case to the police, they should immediately contact and inform the online platform to remove their private videos or photos, and look for the infringers who upload and spread these private videos or photos. If the platform refuses to be removed, the platform and the infringer can be sued together. " Practice emotional expression.

Recently, the research team of Wang Yanyu of the Institute of Natural Science History of Chinese Academy of Sciences released Game Technology — — The phased results of the research report "New technological population in the process of number and reality integration".

　　In this research report, by reviewing the development history of the game industry and related cutting-edge technologies for nearly half a century, the research team tried to analyze the game technology independently, summarized the definition and connotation of the game technology, and for the first time tried to quantitatively evaluate the contribution rate of the game technology in promoting scientific and technological progress in cutting-edge technologies such as chips, 5G and virtual reality/augmented reality. The full report will be officially released in the middle and late July.

　　Game technology has gone through three stages of development.

　　According to the definition of the research team, "game technology" is a technology cluster that realizes large-scale application in electronic games for the first time, with the main goal of enriching and enhancing people’s interactive experience. Because of its interactive, high simulation, strong immersion, real-time rendering and other characteristics, game technology is gradually being applied to many fields of social economy and has become an important technical support to promote the development of digital and real integration.

　　The report points out that the remarkable interesting nature of video games masks the scientific nature of game technology, so game technology has long been ignored by people.

　　In fact, the development of video games is closely related to cutting-edge technology, and almost every technological wave will reshape the ecological outlook of video games. On the basis of reviewing the growth process of video games in the past half century, the research team summarized the game technology into three different development stages — — The era of science, industry and society.

　　It is reported that from the late 1940s to the early 1950s, video games were born almost at the same time as computer science. At that time, video games, because of their clear rules, strict boundaries and strong gameplay, naturally became an important tool for studying and verifying artificial intelligence. The relationship between electronic games and computer science has been maintained in the laboratory for nearly 20 years, and this stage is the scientific era of game technology.

　　After 1972, the entertainment attribute of video games was gradually released. With the rapid development of the Internet, especially the mobile Internet, electronic games have rapidly grown into the most important digital content industry in the world and become an important part of our daily life, so game technology has entered the industrial era.

　　Based on the huge user base and the extreme pursuit of computing power, image display and network bandwidth, during this period, the game industry became the "invisible traction" and "technology incubator" of many cutting-edge technologies such as chips and 5G high-speed networks, and also accumulated a series of unique technical capabilities.

　　In recent years, with the rapid development of digital economy, game technology has also broken through the traditional game scenes and started to be applied to more and more different fields, such as digital cultural protection, industrial simulation, smart city, film and television creation and so on. Therefore, this period was positioned as a social era by the research team, and game technology began to step out of the game industry, becoming the core tool to promote the digital transformation of different industries, move towards the integration of numbers and reality, and build a digital twin, and began to create greater social and economic value in a wider range.

　　Game technology is also a driving force for other digital industries.

　　In this report, the research team first proposed a cross-disciplinary quantitative evaluation method for the contribution rate of scientific and technological progress, and tried to quantitatively analyze the driving force of game technology to other digital industries and related technical systems.

　　By introducing and measuring variables such as the contribution rate of scientific and technological progress in the industry, the correlation coefficient between game technology knowledge maps and other industrial technology knowledge maps, and combining with the public statistical data of the National Bureau of Statistics, relevant ministries and commissions, and industry associations, the research team initially calculated the contribution rate of game technology to scientific and technological progress in the chip industry, 5G high-speed network industry and virtual reality/augmented reality industry.

　　Among them, in 2020, the contribution rate of game technology to the technological progress of the chip industry will be about 14.9%, especially in the emerging technology field represented by cloud games, which is expected to double the demand for cloud computing power, which is of great significance for China to realize autonomous and controllable graphics computing architecture. For 5G and virtual reality/augmented reality, two important infrastructures recognized by the industry in the era of digital and real integration, the scientific and technological contribution rate of game technology is as high as 46.3% and 71.6%.

　　In fact, video games are born out of computer science research. After more than 50 years of development, digital technology related to video games has become a relatively independent technical system and a digital technology group with many possibilities, and has been gradually applied to more social fields, creating more values and possibilities in scientific and technological innovation, real economy, cultural construction and social welfare.

　　Nowadays, electronic games are not only the largest and fastest-growing form of entertainment, but also the game technology in the fields of digital environment, digital avatar and digital assets for a long time, which is likely to play a unique role in the coming digital-real integration society. A large number of new scenes of digital and real integration will emerge in various industries. On the occasion of the tide of the meta-universe, games will become the first application field of the meta-universe.

　　The research team’s attempt to re-examine game technology from the perspective of scientific and technological innovation will not only help the whole society to have a more comprehensive understanding of video games and the technical panorama behind them, but also better guide the healthy and sustainable development of related industries, and provide a new perspective for the systematic research of digital technology.

　　学习大国按

　　3日，第四届世界互联网大会在浙江省乌镇开幕。国家主席最高领袖发来贺信，向大会的召开致以热烈的祝贺。对于习主席的贺信，互联网领域大咖怎么看？今天，乌镇会场里的倪弋，为小伙伴们传来了大咖们的声音。

　　互联网正在深入到社会的方方面面，而这次技术革命的影响力可能超过过去一切技术革命的总和。我们正在讨论网络空间深层次问题，尤其现在显得越来越有必要和越来越有意义。

　　未来30年数据将成为生产资料，计算会是生产力，互联网是一种生产关系。如果我们不数据化，不和互联网相连，那么会比过去30年不通电显得更为可怕。

　　未来30年，互联网将不再是互联网公司的互联网，互联网是所有人的互联网。如果说过去20年互联网从无到有，那么未来30年，互联网将“从有到无”，这个“无”是无处不在的“无”，没有人能够离开网络而存在。

　　习主席在贺信中提到，以信息技术为代表的新一轮科技和产业革命正在萌发。事实上，以人工智能、云计算、大数据为代表的新技术已经开始推动各行各业进行深度变革。在新一轮科技和产业革命面前，过去中国企业主要扮演新技术的跟随者，但今天我们希望成为新技术的驱动者和贡献者，与全球合作伙伴一起协同发展。

　　贺信中强调的“开放”令人印象深刻。数字经济的一个重要特征就是开放分享，它的发展将超越过去传统的行业、地域边界。中国的数字经济将进入快车道，这两年来诞生了移动支付、共享单车等独特创新，我们更应当开放分享、心怀全球、协作创新，让各个国家的人们都享受到数字经济的红利。

　　此外，贺信也提到全球互联网治理体系变革进入关键时期，构建网络空间命运共同体日益成为国际社会的广泛共识。今天每一个人、每一家企业或组织，都通过数字技术紧密地联系在一起，都是“网络空间命运共同体”的组成部分。目前这个“命运共同体”中出现的各种新挑战，需要政府、行业合作伙伴以及社会各界一起探索，进行共建与共治。

　　习主席的贺信从战略高度阐释了这次会议的主题——“发展数字经济 促进开放共享——携手共建网络空间命运共同体”。在重申“四项原则，五点主张”提法同时，此次“发展共同推进、安全共同维护、治理共同参与、成果共同分享”的“四个共同”的提法更具体，简明扼要，十分充实。

　　以数字经济为抓手、为推动力，带动全球经济的发展，是我们共同的期待。当前发展数字经济，一个国家很难关起门来自己发展，首要目标就是要携手共建网络空间命运共同体。习主席在贺信中指出，全球互联网治理体系变革进入关键时期，构建网络空间命运共同体日益成为国际社会的广泛共识。 “大家的事由大家商量着办”，互联网发展没有一个国家是旁观者。

　　我们要从构建网络空间命运共同体的高度来进一步贯彻落实党的十九大精神。首先把事情做好，通过发展数字经济和共享经济等，来实现十九大提出的建设网络强国、数字中国、智慧社会等目标，同时也为推动世界各国共同搭乘互联网和数字经济发展的快车创造条件。

　　中国互联网现在已经处于大踏步向前的发展阶段，并且在发展过程中已经取得了许多成就，包括政府、企业、院校和研究机构等在内的中国社会各领域，都已经参与到互联网的发展之中，这正显示出中国正在利用所有可能的机会，竭尽所能地争取在互联网领域取得更大的进步。

　　习主席在给大会的贺信中指出，“中国数字经济发展将进入快车道”，对此我深有体会。随着人工智能等技术的逐步普及和进入实用化，数字经济与实体经济的结合也越趋明显，不仅对消费者产品和服务带来改变，也会对制造端、供给端产生非常大的影响。

　　数字经济与实体经济结合需要 “跨界”，实体经济中的人既需要对数字经济和新的科技有所了解，也要对自己的领域和专业有深刻认识，如此将两者结合，就会擦出很多火花。

　　科技创新则是促进数字经济与实体经济深度融合的关键。未来，传统产业要继续发展、提升效率、甚至在全球范围内拥有竞争力，一定要靠创新，尤其是技术创新。我们现在处在一个伟大的创新时代，人工智能等技术已经开始不断地与各行各业整合，这不仅仅是百度的机会，也是各行业、乃至中国整体经济的巨大发展机会。互联网行业中常讲“生态”这个概念，如今的“网络命运共同体”就是一个最佳的生态，是一个不断创新、相互依存、共同发展的好生态。

　　习主席在贺信中指出，要推动互联网、大数据、人工智能和实体经济深度融合，发展数字经济、共享经济，培育新增长点、形成新动能。这给实体经济乃至整个经济体系的现代化指明了方向。

　　当前数字经济和实体经济、线上和线下、国内市场和国际市场都紧密融合，零售行业甚至整个经济都进入“无界时代”。作为互联网企业，京东与16万企业紧密合作，在大数据、人工智能、智慧物流等方面具有独特优势，可帮助实体企业打造涵盖研发、生产、流通到售后的“品质供应链”，为企业插上数字“翅膀”，为社会提供高品质商品，为供给侧改革贡献力量。

　　习主席提出“网络空间命运共同体”的理念，非常具有全局性和前瞻性，准确地把握了互联网的快速发展为中国和全球带来的全新机遇和挑战，同时为人类抓住机遇，应对挑战提供了全新的思路和解决方案。

　　我非常认同习主席的判断和观点。随着中国数字经济进入快车道，处于高速发展时期，从全球角度看，互联网已经进入了大安全时代，跨国界的网络攻击无处不在，网络犯罪呈现日益多样化。我们更应该居安思危，紧紧围绕着建立网络空间命运共同体，迎接大安全时代的挑战。

　　——360集团创始人兼CEO 周鸿祎

　　Beijing, December 3, 2017

1905 movie network news On November 17, the hardcore action film released a special feature and stills of "Explosion-Proof Police". The film is directed by the producer, story and general director, and directed by Zhang Jiahui.,,, starring, starring, starring, friendship performances, and special guest appearances. It will be released nationwide on December 8. Zhang Jiahui once again starred as a police officer after many years. The play portrays a good police officer who sticks to the bottom line even if he is physically and mentally exhausted. Outside the play, he and Chan Weiting support each other and pass on the salary.

The movie "Burst Point" tells the story of anti-narcotics chief inspector Li Zhenbang (Zhang Jiahui, played) and undercover police officer Jiang Ming (Chan Weiting, played) secretly executing a plan to hunt down drug dealers. Helpless to encounter danger, Jiang Ming is forced to walk the edge of black and white and gradually lose control. In order to stick to the bottom line, former teammates have each other’s murderous intentions.

"Working Brain" Good people are not easy to do, Zhang Jiahui interprets the "explosion-proof police" who stick to the bottom line without anything

In the "Explosion Point" "Explosion-proof Police" Zhang Jiahui special, Zhang Jiahui plays Li Zhenbang, the chief inspector of anti-narcotics, who abides by the law and is honest and reliable. Even if his family is unhappy and his relatives are alienated due to his long-term obsessive work, Li Zhenbang, the "working brain", still never stops on the road of anti-narcotics. He is not afraid of being injured in a hail of bullets, and he is not afraid of being coerced by his life-threatening partner in a tense confrontation. He is also not cowardly when he fights criminals with his life in a river of blood. In the battle between good and evil, everyone turns into an "urban violent person" to "explode" to fight violence. Only "working brain" Li Zhenbang sticks to the bottom line of a good person and never crosses the line.

Zhang Jiahui interpreted the title of the film "Burst Point", and he admitted that "Burst Point" is more suitable for good people, just like Officer Bang as an ordinary person, he is like a "explosion-proof police", "Burst Point" is a critical point for him to insist on himself in the crime city, but not too much, but not the world. He always has principles against no principles, and has a bottom line against no bottom line. If he can control "Burst", he is still the "working brain" of Officer Bang himself; if he can’t control "Burst", he may also incarnate into "urban ruffians" and turn his friends into enemies. So when temptation, conspiracy, and desperation surged, Officer Bang had no way to avoid it, and had to struggle on the edge of the "breaking point" of justice and reason with "shackles". Could he still choose to stick to himself, stick to his principles, and be the "explosion-proof police"?

Like father and son, Zhang Jiahui and Chen Weiting support each other inside and outside the play to move forward together

The movie "Burst Point" is the first collaboration between Zhang Jiahui and Chan Weiting. In the movie, Zhang Jiahui plays the police officer Bang and Chen Weiting plays Jiang Ming, one is the "explosion-proof police" who adheres to principles, and the other is the "Hong Kong crazy attack" undercover police officer. They are partners who fight side by side. They are brothers who share life and death. They are also like fathers and sons who are warm because of the lack of family unity, but they seem to eventually turn friends into enemies. The relationship between the two becomes a mystery, which makes the audience call "above". The confusion of the relationship within the play did not affect the congeniality of the two people outside the play. As a senior actor who has been working for many years, Cheung Ka Fai is very keen to share and exchange experiences on the set, hoping to bring more experience to the young actor Chan Weiting who returns to the Hong Kong film market. Whether it is a fierce explosion scene or a fist-to-meat action scene, the two give each other their backs, fully trust each other, and hope to shoulder the responsibility of acting together.

The movie "Burst Point" will be released on December 8.

Recently, my friends in Guiyang discovered a novel phenomenon: when they were painting Nezha 2, they noticed an IMAX-GT hall. Many people say that this is the first time they have heard of this type of cinema.

IMAX-GT(IMAX Grand Theater) is an extended version of IMAX technology, which aims to provide viewers with a more shocking viewing experience. Compared with traditional IMAX, IMAX-GT has the following remarkable features:

The screen is larger, covering almost the entire audience’s field of vision, bringing a more immersive viewing experience. The sound effect is stronger, equipped with a higher-end sound system, the sound transmission is more accurate and the coverage is wider, especially in the low-frequency part. In addition, IMAX-GT supports more accurate 3D technology, and with stronger image quality optimization, viewers can get clearer and more realistic effects when watching 3D movies. The ambient light in the cinema has also been optimized to improve the image contrast and color saturation.

The biggest advantage of IMAX-GT is its visual effect. The combination of the huge screen size and high-resolution images makes each frame very delicate, especially in action scenes or movies with rich visual effects, the audience can feel unprecedented visual impact. The sound system is also one of the highlights, and the accuracy and layering of sound effects far exceed that of traditional cinemas. The bass is deep and powerful, and the high frequency is clear and not harsh, giving people an immersive feeling, especially suitable for action movies or science fiction movies. Due to the panoramic display and detailed sound effects, the audience’s immersion is greatly enhanced. Even sitting in the back row of the cinema, you can still feel the layering of pictures and sounds, as if you were in the world of movies. It is also very powerful in the presentation of 3D movies, with clearer pictures, fuller colors and lower eye fatigue, which is especially important for watching 3D movies for a long time.

At present, IMAX-GT cinemas have been set up in some cities in China, such as china national film museum Cinema in Beijing, Wanda Studios in Dongguan, Wanda Studios in Harbin, Dadu Laser in Kunming and Transboundary Studios in Guiyang. Some netizens were surprised that Guiyang has IMAX-GT, and some even joked: "The prejudice in people’s minds is a mountain, but it can’t be blamed. Why is Guizhou a mountain!" Others said that there was such a good thing in Guiyang, but the publicity was not in place, otherwise everyone would have known when Nezha 2 was popular at the box office.

Dear friends, would you like to choose IMAX-GT cinema for better viewing effect? Is there an IMAX-GT cinema in your city?

In the sea area south of Zhuhai, Guangdong, a silver-gray triangular device fluctuates with the waves. It is 27 meters high, weighs about 6,000 tons, and has a plane area of over 3,500 square meters, which is equivalent to the size of about 8 basketball courts.

This is the world’s first megawatt floating wave power generation device "Nankun" independently developed by China, with an average daily power generation of 10,000 kWh, which can meet the daily electricity demand of about 1,500 households.

Wave energy is mainly the energy generated by the periodic movement of seawater along the horizontal direction caused by the action of wind. In the ocean, a huge wave can throw 13 tons of rock 20 meters high, with amazing energy. It is estimated that the global ocean wave energy can reach 2 billion to 3 billion kilowatts, which is close to or even more than 100 Three Gorges hydropower stations.

"Many islands are far away from the land power grid, mainly relying on diesel engines for power supply, with high power generation costs and great environmental protection pressure. China has a long coastline, a large marine land area and abundant wave energy resources, which can effectively reduce the proportion of island diesel power generation. " Liang Xiaobing, deputy chief engineer of Guangdong Electric Power Research Institute of China Southern Power Grid, said that the wave power generation device is equivalent to installing a "mobile charging treasure" for the remote island reef.

It is not easy to make the turbulent waves become a "helper" for power generation. Among them, there are two hurdles that are the hardest to cross.

First, improve energy conversion efficiency. Wave energy is converted into electric energy through three stages: the capture device absorbs wave energy, which is converted into mechanical energy through the transmission device, and then converted into electric energy through the generator set. The energy loss is high, so the capacity of the previous device is several hundred kilowatts.

Wang Wei, a technical expert from Guangdong Power Grid, said that Nankun adopted a triangular design in appearance to absorb as many waves as possible while maintaining stability. What’s more, Nankun also adopts adaptive wave power generation technology, automatically adjusts the generator set according to the wave size, and realizes "all staff are on duty when the wave is big" and "shift rest" when the wave is small, turning the original big and small waves into continuous, stable and smooth current, and the energy capture efficiency is about 28%, reaching the international leading position.

Second, ensure the reliable operation of equipment. The equipment is located in the ocean, so it should not only be able to withstand typhoons, but also prevent seawater. When the wind and waves are extremely heavy, Nankun will start a key-in water mode and dive to a safe depth to resist the typhoon. Up to now, Nankun has successfully withstood the test of typhoons such as Capricorn, Ginkgo biloba and Weipa, and can hold the 5.5-meter-high waves. "’Nankun’ has been designed according to the standards of seaworthy ships and passed the certification of China Classification Society." Wang Wei said.

In addition to wave energy, tidal energy, tidal energy, temperature difference energy and salt difference energy are all available marine green renewable energy. Up to now, the installed capacity of wave energy, tidal energy and tidal energy in China ranks first, second and third respectively in the world, and the marine energy equipment is basically synchronized with the international advanced level, accumulating rich engineering and technical experience, laying a good foundation for realizing large-scale utilization.

The Guiding Opinions on Promoting the Large-scale Utilization of Marine Energy issued this year proposes that the installed capacity of marine energy should reach 400,000 kilowatts by 2030. Support the pilot project construction of marine energy utilization, sum up and popularize the pilot experience, steadily increase the scale of the project, and promote the cost reduction and industrialization development by scale.

The relevant person in charge of the New Energy and Renewable Energy Department of the National Energy Administration said that in the next step, the National Energy Administration will work with relevant departments to solidly promote the survey of marine energy resources in pilot areas and promote them in coastal areas throughout the country in due course; Actively promote the development of offshore wind power and wave energy in the same field, and improve the efficiency of marine resources development; Strengthen policy guidance and institutional guarantee, and accelerate the large-scale utilization of marine energy.

"Every time I see a student playing with a cigarette card, I will confiscate it. This bag is a confiscated cigarette card." On April 25th, a teacher in a primary school in Suzhou reported that some students were playing with "cigarette cards" on the ground recently, and parents were worried that it would affect students’ physical and mental health. To this end, the reporter made a special visit.

The reporter found in a primary school in Sucheng that when going to school in the afternoon, several primary school students gathered on the sidewalk outside the school to play "cigarette cards" together. A student told reporters that the "cigarette card" was cut from the cigarette case, and it only takes a few simple steps to fold it into a "cigarette card" that can be patted and played. The game of "cigarette card" is also very simple. Put the "cigarette card" on the ground, slap the ground with both hands bulging empty palms, and the card will win if it is turned over. When reporters asked where their "cigarette cards" came from, some said they were cut from empty cigarette cases at home, some said they were won, and some said they were bought by their parents online. "Sometimes I will pick up empty cigarette cases on the road." A primary school student said. During the interview, the students said that "cigarette cards" are also graded. The more expensive cigarettes are, the higher the grade of "cigarette cards" is. In the process of playing "cigarette cards", many students know many different brands of cigarettes, and the corresponding prices of various cigarettes are also well understood by students.

Searching for the related words of "cigarette card" on an e-commerce platform, words such as "excellent card", "rare card" and "out of print" appear, including 5 pieces for sale, 10 pieces for sale, 100 pieces and 500 sets, with prices ranging from several yuan to 100 yuan, and the highest monthly sales volume is over 20,000.

"The’ cigarette card’ is folded into a cigarette case, and children are exposed to tobacco prematurely, fearing that it will have an adverse impact on their growth." Ms. Gao, a citizen, told the reporter that when her child was in the fourth grade of primary school, she saw a "cigarette card" in her hand when she picked up her child from school. At first, she thought it was an ordinary card, but she didn’t care. When she got home, she found it was a "cigarette card". The child said it was sent by her classmates and said that there were many people playing "cigarette cards" in the school. She was worried about this.

A primary school teacher in Sucheng said that some students have to practice the "trick" of taking a "cigarette card" in class, and they can take out a "cigarette card" in their clothes pockets and get together to play after class. "I have said many times in the class about playing cigarette cards. When I see a student taking a cigarette card, I will confiscate it and tell the students about the dangers of playing cigarette cards. Now there are far fewer students playing cigarette cards in the class."

"Playing’ cigarette cards’ is not conducive to students’ physical and mental health. We will tell them about the negative effects of playing’ cigarette cards’, help them establish correct values, and call on the society to pay attention to students’ growth environment." Wu Changhu, director of the Academic Affairs Office of Suzhou Jiuxiao Education Group, said that the harm of indulging in "cigarette cards" can not be ignored, which will distract children’s attention, make them unable to concentrate on their studies, affect their studies, and may also lead to children’s psychological comparison. Moreover, the "cigarette card" is related to cigarettes, which will make children exposed to tobacco prematurely and have a negative impact on their physical and mental health. Teachers and parents should strengthen education and guidance for students, make them realize the harm of indulging in "cigarette cards", and stop those who play "cigarette cards" in time to guide students away from bad games and reduce their chances of exposure to tobacco. At the same time, we should communicate effectively with students to understand the reasons why they are interested in "cigarette cards", and then provide healthier and more educational games or activities according to their needs. In addition, a home-school cooperation mechanism should be established to jointly pay attention to children’s growth and create a healthy and harmonious growth environment for them.

　　CCTV News:The vast ocean is becoming a lush blue pasture. Advancing deeper and farther into the sea can make the blue granary more full. It is very important to strengthen the marine fishery germplasm resources for building the whole industrial chain of modern marine pasture.

　　In the morning of October, 2023, a harvest at sea was going on, and Jinghai 001, the largest deep-sea intelligent cage in Asia, was lifting the net to collect fish.

　　The growth of the catch has exceeded expectations, and the excitement of buyers is self-evident, and the mystery of harvest comes from this "deep-sea fish pond" far from the coastline.

　　It takes about four or five hours to reach the core area of Bohai Bay by boat from Nanhuangcheng Island, where Jinghai 001 is located.

　　The cage is 68 meters long and 68 meters wide, and its area is equivalent to the size of 11 standard basketball courts. It can hold 70,000 cubic meters of seawater and raise 1,000 tons of fish at a time.

　　The huge and sturdy cage provides an incomparable growth environment for deep-sea fish, and intelligence makes every fish from the deep sea have exclusive identity information.

　　On the blue sea, there are not only intelligent "deep-sea fish ponds", but also "mobile marine pastures" in more distant waters.

　　This "Big Mac at Sea" is the world’s first 100,000-ton intelligent fishery large-scale aquaculture ship, and the most important "resident" on board is the large yellow croaker, which ranks first among the "four major seafood".

　　There are 15 breeding cabins like this on the Guoxin No.1 engineering ship. This "Big Mac" at sea has a displacement of nearly 130,000 tons. To achieve "balance of payments", it naturally needs the same amazing water supply. It can find the freshest and most suitable seawater for large yellow croaker in the far-reaching waters 100 nautical miles offshore.

　　Brand-new breeding mode needs to be equipped with brand-new automation equipment. As soon as the "Fandianer" arrived, the feeding system was automatically turned on, and the large yellow croakers lurking in the cabin got up in droves to feed. Such a scene was staged in the morning and evening.

　　Seeding, feeding, changing water, catching, processing and transporting … … The intelligence of the whole process makes this huge marine ranch become a giant offshore fishery factory at the same time.

　　Relying on the pioneering "on-board cabin culture" mode, Guoxin No.1 aquaculture ship can supply 3,700 tons of high-quality fish and 650 tons of high-quality protein every year. At harvest time, the large yellow croaker in the cabin will be directly transported to the dormancy pool through the fish suction pump and conveyor belt, where it will be quickly cooled, dormant and fresh.

　　Live fish are caught, frozen in ice slurry and transported by cold chain. These high-quality fish can be sent to consumers’ tables in the first time.

　　High-quality animal protein makes the food from the sea not only exclusive to coastal residents, but the fishing season of three or four months every year makes the huge market demand face the gap of wild aquatic products supply. As an important supplement, aquaculture contributes 80% to the market.

　　In the past 32 years, China’s aquaculture output ranked first in the world, and about 40% of the global aquaculture products came from China. However, the proportion of marine fish is not high in such a huge aquaculture output in China.

　　The vast ocean is becoming a lush blue pasture. Advancing deeper and farther into the sea can make the blue granary more full, and expanding the marine fishery germplasm resources is also very important for building the whole industrial chain of modern marine pasture.

　　The National Marine Fishery Biological Germplasm Resource Bank is the largest investment, the largest preservation scale and the most advanced facilities in China, and has collected and preserved more than 140,000 samples of various marine fishery biological resources.

　　As the "chip" of marine granary, excellent aquatic germplasm is the foundation of modern fishery development. In this germplasm resource bank, all kinds of precious marine fishery biological germplasm resources can be safely preserved. At the same time, new breeding technology has created more abundant possibilities for the sustainable development of aquaculture.

　　Up to now, 283 new aquatic products have been approved by the state, and more new technologies have also made breakthroughs and innovations.

　　At present, the contribution rate of agricultural science and technology progress in China has reached 62.4%, and the contribution rate of improved varieties to agricultural production has reached more than 45%. Deeper and farther waters are becoming the blue ocean for cultivating fishery "chips". The pace of advancing to the far-reaching sea is accelerating the birth of new quality productivity.
