In previous years, the drama involved in the case mainly showed the case and the process of solving the case, which may involve many negative factors. Once the start is not good, the angle is wrong, and the interest point deviates, it will become a product of uncertain factors such as showing the criminal process, portraying the criminal psychology, exposing the means of detection, causing social terror and so on.

The network has expanded the concept of suspense theme, and at the same time, suspense theme, whether it is based on cases, or fighting wits and burning brains, has shown a realistic trend of change.

The greatest aesthetic feature of traditional film and television drama series is realistic expression, and cool feeling manufacturing is the symbolic artistic style of online drama. Network dramas use the cultural production mechanism formed by network culture to strengthen the visual expression of our traditional realistic spirit, make the realistic things more visible, and are especially welcomed by young audiences, thus continuing the realistic spirit. At the same time, it enriches the connotation of cool feeling with the spirit of realism, making the consumption of cool feeling less pale and empty. Internet dramas with suspenseful themes such as Hidden Corner and The Wind Rises in Luoyang all have realistic connotation behind them, but the expression form it takes is a new form from the Internet, and this aesthetic fusion formed in the process of two-way travel is also one of the reasons for the emergence of fine products.

During the period from the end of 2021 to the beginning of 2022, there are two works worthy of attention. One is "Opponent", as a network-TV simulcast drama, which takes national security as the theme and interprets a spy war story in a narrative way that conforms to the network aesthetics. The other one is Dui Dui, which can be classified as a drama involved in the crime, and it is also suspenseful. The whole drama is constantly "cool", and it is the first online drama to win the "net logo". As far as the integration mentioned above is concerned, it seems to have a more symbolic significance. In fact, since it is integration, it is not a substitute for each other, but a new life. Just like when Ling Huchong just learned the star-sucking method, there may be some conflicts in the early "two magical powers", but we believe that after a period of adjustment, there will be an effect of 1+1>2, presenting us with a brand-new TV drama (online drama) aesthetics created by contemporary China.

We can take two plays, Illustration of Hunting Crime and Dawn of the River as examples. They are all suspense themes, and there are cases behind them, but the main digging point and theme conception of the two works are not the case itself. Its change has just injected more life connotation and social emotion into the suspense theme, and transformed the TV series involved in the case that we think is difficult to grasp into realistic works.

The Book of Hunting Crimes must sound like a story of police solving crimes, but there is no specific case, but it describes a new screen image of film and television — — Criminals’ portraitist provides a fresh professional type and a fresh screen image from the novelty of characters, and also provides a new angle for suspense subjects.

Jiang Zhao Dawn seems to be a drama involving cheating and killing his wife, but its difference lies in injecting more social connotation and emotional concentration in life. This drama is about how a psychologically depressed woman redeems herself in the face of difficulties. It does not focus on the case itself, but focuses on how ordinary people deal with emotional pressure in social life and family life, how to face difficulties, how to face all kinds of uncertainties, and even the living state, emotional state and psychological state when life is threatened. This is the so-called reality. If there is no reality, there will be no empathy and resonance of the audience, and it will not have such a great impact.

Therefore, these two dramas have broken through the traditional suspense types and traditional stories involving the case, regardless of originality, reality or spiritual expression. They have won praise with innovative techniques and high-quality production.

There are at least two ways to express the realistic content of suspense dramas. One is to weave a story directly from real life and real cases, including some case news, which is similar to what we often say, "take all kinds of things and combine them into one." The other is to tell an ancient history, legend and even a completely overhead suspense story, but this story is full of strong realistic concern. The former case, such as the beginning; In the latter case, for example, The Wind Rises in Luoyang, both the spatial metaphor of urban settlements, such as gods and bad wells, and the process of changing fate from the bottom are full of "reality".

It is worthy of recognition that the social consciousness rooted in reality and the deep motivation of audience psychology have injected social hot topics with speculative characteristics and ethical values into suspense dramas, which is also the content charm of suspense dramas. Disappearing Children talks about social phenomena through suspense, and substitutes many social issues such as family education, old-age care and the safety of women living alone into the plot. "Disappeared children" finally returned home safely, and talked about the core theme of "healing and redemption", which reflected that suspense dramas actively led the social fashion of being good, good and upward, and deeply cultivated and polished the value connotation and emotional orientation of suspense dramas on the fertile soil of reality, which triggered the audience’s empathy.

"Reality" is an important core of the online drama series with suspense theme, and this core lies in the fact that "reality" happens around you. Therefore, it will artificially create a sense of being there. When Don’t Talk to Strangers exploded, it became a buzzword, and even a generation’s understanding of society fully showed the strength of "reality" in suspense dramas. However, as teacher Li Jingsheng said, such dramas may "cause social terror". This requires some neutralization and guidance.

These works are more deeply involved in social reality. While affirming the progress of the times and the achievements of social development, they also pay attention to various practical problems. They emphasize social benefits and value orientation, explore people’s living conditions and the complexity of human society with the help of suspense, reflect the style of the times and show cultural charm, which can not only meet the entertainment needs of the audience, but also cultivate their aesthetic taste and produce social influence and cultural value.

It can be seen that the creators of suspense dramas actively follow the trend of realism, pay attention to social reality and people’s living conditions, reveal the essence of life and the characteristics of the times, write a rich and full spiritual world of human beings, and try multiple explorations in the field of themes.

Online drama series can directly reflect the state of young people’s lives at present than TV series. Suspense theme, as one of the themes of this year’s online drama series, has also become a window for us to observe the state and preferences of young audiences.

The popularity of online dramas with suspense themes such as The Beginning, Twinkle, Twinkle, Twinkle, Stars, Dawn in the River, etc. this year shows two characteristics of this generation of young audiences: first, the improvement of aesthetic taste. The coolness of the above-mentioned online dramas is not a realistic coolness, but a brain-burning, curious and intellectual gymnastics, in which besides the improvement of aesthetic taste, there is also an improvement of artistic accomplishment; Secondly, the daily life in the epidemic is relatively poor, which especially needs the stimulation of literature and entertainment. The suspense theme has obvious decompression effect on young audiences. This can be well shown in the series "Coward" and "Meritorious Service" which have not yet been released, such as "Snowy days in Northeast China = the sense of isolation caused by people facing nature = the atmosphere of terror".

The combination of these two features will give birth to a new expression, such as unexpected arrival. Like the previous Under the Sun, it creates a different suspense theme, that is, it uses suspense to express the topic of "women’s growth" in the cloak of urban emotion. Since the first half of my life, "a stay-at-home wife is in trouble" has become a motif with a strong sense of the times. Unexpected arrival is no exception, and it also incorporates "sadomasochism", a network element that highly meets the requirements of "cool feeling" and a strong urban atmosphere. From this, we can see that the younger generation of viewers no longer simply believe in the "silly and sweet" "princess dream". They are aware of the need to strengthen the ability of "fighting monsters and upgrading" while maintaining their dream fantasy, and walk out of the greenhouse in captivity with high morale. If we think about the change of epidemic situation in three years and the popularity of this mystery drama, we may have more new understanding of this generation of young people.

In the past, we used to understand "mainstream audience" as being biased towards middle-aged and elderly people, who used more TV, newspapers and radio. However, from the perspective of consumption power, network communication power and social influence, young people over the age of 18, even between the ages of 16 and 35, are becoming mainstream audience today. Therefore, through the docking and development of suspense themes, we can see that young people are paying attention to social topics, and they are thinking about art, or they are paying some shallow or deep attention to society.

Of course, what supports this turn is its innovation at the whole narrative level, which is not limited to self-operation, spontaneity, autonomy and self-action at the network level. In the narrative innovation and discourse innovation of online drama series, we can clearly see a new trend in the process of network development, that is, the drainage and integration of various media has brought new narrative discourse and produced a new narrative form.

For example, the circular narrative of "infinite flow" used in The Beginning and Twinkle, Twinkle, Twinkle, Twinkle and Bright Stars was once one of the classic narrative modes of film and television, and the classic film "Run Lola" was used. The classic narrative created on the big screen is used in the online drama collection and recreated according to the audience’s viewing habits, which has created the reputation and traffic of online drama series with suspense theme today. This shows that the success of our online drama series in the whole viewing level is not only the theme, but also the synergy between the competitiveness of the theme and the innovation of narrative discourse, and between the development of online drama series and other online audio-visual products.

From The Longest Day In Chang’an to The Mysteries of the Tang Dynasty, suspense-themed online drama series formed a new narrative form of "history+suspense" during the transformation of historical resources. If The Longest Day In Chang’an, under the surface suspense theme, through the modern adaptation of costume characters, shows his concern for the current real life, as well as his thinking about practical problems and social psychology, it is a narrative exploration of suspense-themed online drama series; Then, the upsurge of "strange aesthetics" set off by "Records of Mysteries in the Tang Dynasty" on the whole network realized the innovative combination of "strange interest" and "ancient meaning" at a deeper internal mechanism level. "Seeing all beings under a strange case", the drama organically integrates anecdotes, strange events and mysterious cases with the historical humanities, folk customs and strange legends of the Tang Dynasty, sews up the narrative gap of suspense texts from the historical depth to output modern values, and the visual effects skills of "emptiness" and "reality" create the modern style of Chinese aesthetics, which well meets the aesthetic needs of the audience for "high intelligence", experience and excitement.

The new narrative discourse and narrative patterns stimulate the innovative vitality of suspense texts, and the drainage and integration of various media help suspense dramas to achieve "expanding the circle" on the basis of "breaking the circle" along the sustainable, multi-level and three-dimensional communication path, and achieve more innovative and energetic high-quality development.

　　On April 3rd, IT House reported that the technology media Android Authority published a blog post yesterday (April 2nd), reporting that after Microsoft recently updated Phone Link, the application once again supported mirroring sensitive notifications (such as double verification code) in Android phones to Windows PC.

　　After the update of Android 15, the system will mark the notification containing the double verification code as "sensitive content" and hide the specific information, only displaying "sensitive notification content has been hidden". This move aims to prevent malicious applications from stealing verification codes, but it makes it impossible for PC-side tools such as Microsoft Phone Link to mirror such notifications.

　　Phone Link originally relied on the notification listener API of Android standard to achieve cross-device synchronization, so its function is limited by the new regulations.

　　To solve this problem, Microsoft applied for Android’s Companion Device Computer Role for Phone Link. This permission is only available to pre-installed applications of equipment manufacturers, default launchers or wearable/computer supporting applications, allowing applications to read sensitive notifications.

　　Note of IT House: Users need to manually authorize on Android devices and agree that Link to Windows "reads all notifications (including contacts, messages and photos)". At present, this function only supports devices pre-installed with Link to Windows such as Xiaomi 15 Ultra and Samsung Galaxy S25 Ultra.

　　If the phone is not pre-installed with Link to Windows, users can restore the function through two temporary schemes: disabling the notification processing service of Android System Intelligence, or manually granting the receive _ sensitive _ notifications permission through ADB command. However, the latter involves the option operation of developers, which is difficult for ordinary users to implement.

　　

　　Peng Jihe is taking care of his injured son.

　　

　　　　Rescue the scene

　　

　　　　The injured couple

　　

　　Zhang Shuiwang, who was slightly injured.

　　-The Futian section of Pingxiang of Shanghai-Kunming Expressway had a car accident yesterday.

　　-Eight people were killed and 18 injured.

　　News tip: At about 0: 15 yesterday, a serial car accident occurred at the 506 public pile of Futian section of Pingxiang of Shanghai-Kunming Expressway. After a sleeper bus rolled over to avoid the truck, it was hit by a big truck. Three people died on the spot, five died after being rescued by the hospital, and 18 passengers were injured to varying degrees.

　　The passenger car avoided the sudden rollover of the truck.

　　When the reporter rushed to the expressway, the scene was still being cleaned up. High-speed traffic police and Pingxiang public security, fire protection, 120 and other departments are rescuing the wounded. The reporter understands that the cause of the accident was a Zhejiang C08980 sleeper bus from Hunan to Zhejiang, which was caused by avoiding the rollover of a truck in front. A driver on the sleeper car said: "When the incident happened, the car was driving on the highway, and suddenly a truck in front stepped on the brakes, and our driver also stepped on the brakes quickly." At this time, the bus rolled over, and a 2-year-old boy in the car died on the spot in the rollover. "

　　Zhang Shuiwang, the lightest injured passenger, told reporters that at 2 pm on December 12, he and several fellow villagers got on the bus from their hometown of Longche Township, Longshan County, Hunan Province, and prepared to return to Wenzhou, Zhejiang Province. At that time, the sleeper bus in which they were sitting suddenly rolled over. At that time, the passengers in the whole bus were still asleep. When he woke up, the first thing he heard was screaming and crying.

　　The boy was knocked out of the window when he urinated.

　　Passenger Peng Jihe, 31 years old, has been working in Wenzhou with his wife for many years. On December 12th, Peng Jihe deliberately went home to bring his son Peng Zhengquan back to Wenzhou for the New Year. In this car accident, Peng Jihe was injured in many places. His son Peng Zhengquan was sent to the intensive care unit because of a broken head and a broken right foot.

　　According to Peng Jihe, before the incident, he and his 3-year-old son Peng Zhengquan sat in the first row of the sleeper. He woke up because his son had to pee. With the rapid braking sound, the sleeper car he was riding suddenly rolled over. Later, he found that his son was gone. When he saw the broken window and the glass all over the floor, he immediately thought that his son had been knocked out of the car.

　　Later, he endured the pain to see his son. He first found a boy with blood all over his head lying on the ground not far from the bus. At this time, he quickly confirmed from other passengers that the boy was dead. Just as he was about to pick up the boy, he soon found that a few meters in front of the bus, his son was crying for his father.

　　The rollover bus was hit by the truck behind it again.

　　At noon on the 13th, in the north branch of Pingxiang People’s Hospital, the reporter saw some passengers injured in the accident. The injured Zhang Shuiwang said: "When the accident happened, we were all sleeping. Our position at that time was close to the rear of the carriage. After the car rolled over, the glass in the rear trunk was all broken, and it was dark outside. I saw an exit and climbed out of the carriage. " Chen Desheng, a fellow villager of Zhang Shuiwang, told reporters that another terrible thing happened after they climbed out for more than ten minutes. A truck couldn’t dodge, and suddenly rolled over and hit the bus.

　　The reporter learned from the relevant departments that after the bus rolled over for more than ten minutes, the surrounding light was not good. A truck of Fujian F50575 hit the back of the bus and turned to the ground, and the truck driver died on the spot. Passengers sitting on the edge of the sleeper waiting for rescue were injured by trucks, and many people were killed or injured.

　　Husband and wife cheat their families in good faith after being injured

　　According to reports, after the first car accident, many passengers who woke up from their dreams were launching self-help and rescue, but they were knocked down by the big trucks coming from behind. Passengers Zheng Peanut and Li Demei were injured while saving people. For fear of affecting their son’s study in high school, the couple climbed out of the car, held back the pain and called their family, and lied in good faith that they had something urgent in Pingxiang and might travel home for a few days after finishing their work in Pingxiang.

　　The cause of the accident is still under investigation.

　　The reporter learned from the relevant departments of Pingxiang City that after the incident, many departments in Pingxiang City quickly rescued them. Eight people were killed and 18 passengers were injured in the serial car accident. At present, the injured passengers have been sent to the hospital for treatment, and their emotions are stable. On the morning of December 13th, leaders of Pingxiang Municipal Committee visited the injured in the hospital and asked relevant departments to properly handle the aftermath. It is also known that at 8 am yesterday, the Futian section of Pingxiang of Shanghai-Kunming Expressway resumed traffic, and the cause of the accident is still under investigation.

　　[Report from the press conference of the State Council Office] 　

　　Guangming Daily, Beijing, July 22nd, by Guangming Daily reporter Yuan Yufei

　　On July 22nd, the State Council held a press conference on the traceability of Covid-19. Xu Nanping, Vice Minister of Science and Technology, Ceng Yixin, Deputy Director of the National Health and Wellness Commission, Wang Chen, Vice President of China Academy of Engineering, Dean of Peking Union Medical College and Director of the National Respiratory Medicine Center, Liang Wannian, Chinese leader of the China-World Health Organization joint research group on Covid-19 traceability, Yuan Zhiming, director of Wuhan National Biosafety Laboratory of Chinese Academy of Sciences and researcher of Wuhan Institute of Virology, and other authoritative experts actively responded to the hot issues of the traceability of the new coronavirus concerned by Chinese and foreign media.

　　Q: Is the report on global traceability in Covid-19 released by the World Health Organization on March 30th authoritative?

　　Ceng Yixin:The problem of virus traceability is a complex scientific problem. Since the outbreak of the epidemic, every responsible country and every responsible scientist is eager to find out the source of Covid-19. This is of great significance to prevent similar epidemics from happening again.

　　On March 30th this year, the World Health Organization officially released the joint research report "Global Traceability Research in Covid-19: Part of China" convened by WHO, and the global traceability research made a good start.

　　Governments, scientists and the media all over the world are very concerned about this report. Since its release a few months ago, more and more scientific evidence shows that this report is valuable, authoritative and can stand the test of science and history. The conclusion of the report is scientific, and the process of production always adheres to scientific principles.

　　This traceability research report is the China part of the global traceability research. The expert group draws the following conclusions: Coronavirus, which is closely related to Covid-19, has the highest homology with Covid-19 in terms of sequence, but these viruses are still not enough to prove that they are the direct ancestors of Covid-19, and there is still a certain gap. Combined with the research results of clinical epidemiology, animal and environmental detection, the joint expert group finally determined several possibilities for the virus to appear: the first one is "possible to relatively possible", and zoonosis directly overflows, that is, it directly overflows from animal hosts to people. The second is "more likely to be very likely", which is introduced through an intermediate host. Generally speaking, the natural host of the virus is an animal, and then it transits to people through the intermediate host. The third is "possibility", which is introduced through the cold chain. In some sporadic epidemics in various places last year, it was found that cold chain transmission may introduce viruses. The last one is the introduction of "extremely unlikely" in the laboratory.

　　In the next stage, the traceability work should be carried out under the overall coordination of WHO, and on the basis of the first stage of research, excellent experts from many countries should be organized to carry out in-depth work, scientists should be the mainstay, exchanges and cooperation should be strengthened, and the traceability work in Covid-19 should be carried out on a scientific track.

　　Q: Is Covid-19 naturally produced or caused by human factors?

　　Ceng Yixin:I really want to talk about my views on the second phase of the virus traceability plan released by WHO on July 15th. To tell you the truth, I was very surprised. Because in this plan, the hypothesis that "China violated laboratory regulations and caused virus leakage" is one of the research focuses. From this point, I can feel the disrespect for common sense and arrogant attitude towards science revealed in this plan. It is impossible for us to accept such a traceability plan.

　　What is the purpose of traceability? It is to find out the source of the virus and then take effective measures to prevent similar epidemics from happening again. Therefore, we must promote this work in accordance with scientific principles and rules. This is the attitude of the China Municipal Government.

　　So far, none of the staff and graduate students of Wuhan Institute of Virology has been infected with COVID-19. Wuhan Institute of Virology has not carried out research on the gain function of coronavirus, and there is no so-called artificial virus. So where did the virus leak due to violation of laboratory regulations come from? Therefore, this formulation violates both common sense and scientific laws. More importantly, the WHO expert group personally visited Wuhan Virus Institute, and reached the conclusion that the virus is extremely unlikely to be leaked from the laboratory. They are all very authoritative and experienced experts in various fields carefully selected by WHO. So we should respect their conclusions.

　　Yuan Zhiming:The Wuhan Institute of Virology has repeatedly responded to the rumors about the leakage of virus laboratories. Covid-19 originated from nature, which has become a general consensus in academic circles. I want to emphasize that before December 30, 2019, Wuhan Institute of Virology had not contacted, preserved or studied Covid-19. Wuhan Virus Research Institute has never designed, manufactured or leaked Covid-19.

　　Facing the sudden outbreak of COVID-19, Wuhan Institute of Virology quickly identified novel coronavirus with the advantages of platform, technology and talents accumulated for a long time, isolated the virus strain, determined the whole genome sequence, and submitted the whole genome sequence to the United Nations World Health Organization on January 12, 2020. These important research results have provided a foundation for the global antiviral drug screening and vaccine research, and also won time for the global fight against the epidemic.

　　Q: Is the original data of early communication in Wuhan public?

　　Yuan Zhiming:The structure and content of the database of Wuhan Institute of Virology are still in the process of continuous improvement. At present, the database is shared within Wuhan Institute of Virology. After analyzing and systematically sorting out some original data in the database, the staff will publish the research results in the form of papers, and display and retrieve them in the database in a visual way. After analyzing and sorting out the original data of scientific research, it will be published in the form of papers, and then the database will be made public. This is the practice of scientific and technological circles, and the Institute of Virology will strictly follow the rules of scientific and technological circles to display and share our scientific data.

　　Wuhan Institute of Virology has always insisted on the timely sharing of scientific research information, and we released the whole genome sequence to the World Health Organization in time. As early as February 3, 2020, Shi Zhengli’s research team published a research paper in Nature, proposing that Covid-19 came from nature. After we found that several drugs have antiviral activity at the cellular level, we published the research results in international magazines on February 4. At the same time, Wuhan Virus Research Institute also actively participated in the international video and audio conference held by the World Health Organization, and timely shared our research results in animal model establishment, antiviral drug screening, inactivated vaccine development in COVID-19, etc.

　　Q: What do you think about the possibility of virus spread caused by trade in cold chain products?

　　Wang Chen:The role of cold chain in the spread of infectious diseases is a new phenomenon. From Beijing Xinfadi epidemic situation and Qingdao epidemic situation, we can see such a close relationship, that is, the patients have been exposed to the cold chain, and no other possible virus sources have been found outside the cold chain.

　　In the detection of virus nucleic acid, cold chain goods nucleic acid detection is positive. Especially in the Qingdao epidemic, not only the virus nucleic acid positive was detected on the surface of cold chain items, but also the virus was isolated and cultured, which confirmed that there was a live virus on the surface of cold chain items. Combining these two points, the chain of evidence is gradually complete.

　　In the process of further virus traceability, we especially suggest that the cold chain should be regarded as a key traceability clue. At present, under the background of international trade, people and goods exchange frequently all over the world, and people in the cold chain environment — The spread of things has increased the complexity, which is particularly worthy of investigation and research.

　　Guangming Daily (July 23, 2021, 09 edition)

　　Science and Technology Daily, Beijing, October 17 (Reporter Gu Gang) Many mammals spend the cold season by hibernating. The lower the body temperature of hibernating animals, the more energy consumption can be reduced. But this is not all good. A recent study by the Veterinary University in Vienna, Austria, found that lower temperature tends to increase telomere contraction, which may accelerate cell death. To avoid this result, animals need to consume a lot of energy to repair cells.

　　Researchers have found that during hibernation, mammals with lower body temperature can reduce their physical exertion by more than 90%. In the absence of food, reducing energy consumption is very beneficial to the survival of animals. However, animal hibernation at low temperature can cause problems such as telomere contraction. In the experiment of forest Dormouse and garden Dormouse, it was found that Dormouse wintering at higher body temperature has longer telomeres, but it also consumes more energy. Researcher Julia Novak explained: "This seems to be a compromise between maintaining complete telomeres and cell survival, and minimizing energy consumption by hibernating at low body temperature."

　　The researchers also found that there are significant differences in telomere shortening between forest Dormouse and garden Dormouse when they hibernate at different temperatures. They were put into hibernation at 3℃ and 14℃ respectively in the laboratory. Dormouse consumes more energy at 14℃ than at 3℃, while chromosome telomeres are much better at 14℃. This new understanding supports the widely accepted hypothesis that hibernation also has a price.

　　Novak believes: "Deep hibernation is related to the cost at the cellular level, that is to say, the recovery of telomere length after shortening must be at the expense of animal physical consumption. Previous scientific assumptions may overestimate the benefits of deep hibernation in animals that can reduce physical exertion. "

　　Although hibernation has many advantages, the research also found that it has related problems. Due to the decline of immune function, slow response and increased oxidative stress, frequent awakening of animals from hibernation will also lead to a rapid reduction of energy reserves, and the up-regulation of metabolism is related to the production of reactive oxygen compounds, which will lead to a faster shortening of telomeres.

　　The length of telomeres is usually used as a sign of aging, which shortens after each somatic cell division. If its length cannot be recovered, the cell will eventually die. During hibernation, telomere recovery is destroyed.

　　This study is also of great significance to human medicine. Studies have shown that chronic human stress will accelerate telomere shortening. On the contrary, lifestyle changes will slow down telomere shortening, which will have a positive impact on the aging process of cells and the whole organism.

　　　　　　 CCTV News:To pay attention to the recent subtle changes between Russia and Ukraine. A year ago, on November 25th last year, three Ukrainian military ships forcibly broke into the Kerch Strait and entered the Russian closed waters. At that time, the Kerch conflict triggered diplomatic friction between Russia and Ukraine, which Russia regarded as a "serious provocation" and detained all the crew and ships, while Uzbekistan identified the Russian ships as "attacking first" and insisted that the navigation was "peaceful" and "legal". At present, the "Kerch conflict" between Russia and Ukraine has been deadlocked for a year, and now it has finally ushered in a peaceful result.

　　　　　　 Russian-Ukrainian President telephoned to discuss issues such as the transfer of ships by Russia.

　　　　　　 On the 25th local time, the Russian Kremlin issued a statement saying that Russian President Vladimir Putin had a telephone conversation with Ukrainian President Zelensky on the same day at the invitation of Uzbekistan. The two sides discussed the handover of three Ukrainian naval vessels detained in the Kerch Strait conflict last year, and held consultations on natural gas transmission and other issues. The Kremlin said that the leaders of the two countries indicated that they would continue to maintain communication at all levels.

　　　　　　 The four telephone conversations between Russian and Ukrainian presidents are expected to pick up.

　　　　　　 In fact, since Zelensky was elected president of Ukraine in April this year, Russia and Ukraine have actually started to actively and tentatively improve their relations. In July, Putin and Zelensky spoke by phone for the first time; Since then, the two men have talked again in August and September respectively, and this time yesterday was the fourth telephone conversation since Ukrainian President Zelensky took office; The warming of this relationship continues. In September, Russia and Ukraine exchanged people who had been detained before; On the 18th of this month, Russia also returned the Ukrainian ship that was detained a year ago, which means that the Kerch Strait conflict has basically come to an end.

　　　　　　 The fourth call between Russian and Ukrainian presidents focused on three issues.

　　　　　　 In addition to ending the one-year stalemate, the fourth conversation between Russian and Ukrainian presidents also discussed two other important topics, namely, the "Normandy model" involving foreign affairs and internal affairs and the "natural gas bill". On the 25th local time, the Kremlin said that a four-nation summit of "Normandy Model" including Russia, Ukraine, Germany and France will be held in Paris, France on December 9th, and Russian President Vladimir Putin will confirm his attendance in Paris. The Normandy Model was founded in June 2014. On the occasion of commemorating the 70th anniversary of Normandy landing, France invited Russian, German and Ukrainian leaders to hold the first consultation on the situation in Ukraine in Normandy. So, what did the four-nation summit meet in early December? How to talk about? Can it be a good medicine to solve the Ukrainian problem?

　　　　　　 The leaders of Russia and De Fauw will gather in Paris next month.

　　　　　　 On the 18th of this month, according to the website of Kegong, Russian President Vladimir Putin and French President Macron held a telephone conversation that day. The content of the conversation was "mainly concerned about the situation in Ukraine and the preparations for the four-party talks in Normandy". Earlier, Germany confirmed that German Chancellor Angela Merkel would attend, and the Ukrainian President’s Office also confirmed the meeting date. Not surprisingly, the leaders of Russia, Germany, France and Ukraine will gather in Paris. If this summit is successfully held, it will be restarted after the interruption of the second "Normandy Model" summit in 2016.

　　　　　　 After a lapse of three years, the "Normandy Model" was restarted, and it was widely believed that Russia and Ukraine might engage in a confrontation over the future of the Minsk Agreement. Earlier, the leaders of Russia and France said in a telephone conversation that the talks should contribute to the rapid and full implementation of the Minsk Agreement. Putin stressed that "Kiev should first ensure that the law recognizing the special status of Donbass comes into effect." Russian Foreign Minister Lavrov also said that the conditions are ripe for the summit meeting of the four countries, but the outside world should not "expect too much". Moscow still hopes that Paris and Berlin can persuade Ukraine to accept the indisputable Minsk Agreement.

　　　　　　 In April 2014, a large-scale conflict broke out between Ukrainian government forces and civilian armed forces in the Donbass region of eastern Ukraine (including Donetsk and Luhansk States). Under the mediation of the international community, the two parties to the conflict reached a ceasefire agreement in Minsk in September 2014 and February 2015, namely the Minsk Agreement. According to the analysis, at the end of this year, the Minsk Agreement is about to expire, and Russia and Ukraine have been in intensive contact recently — — The exchange of detainees and the return of ships are also regarded as goodwill released by Russia before the "Normandy Model" summit. However, Ukraine has always taken a firm attitude towards the Donbass region, and it is still uncertain whether the "Normandy model" can become a good medicine for the situation in Ukraine.

　　　　　　 Russia and Ukraine may reach an agreement on the "big natural gas bill"

　　　　　　 As the Minsk Agreement is about to expire at the end of the year, there is also a "natural gas contract" related to Ukraine’s people’s livelihood, and this issue has also become the focus of the Russian-Ukrainian president’s telephone discussion.

　　　　　　 The "Beixi -2" natural gas pipeline project aims to lay a natural gas pipeline from Russia to Germany via the bottom of the Baltic Sea, and transport Russia’s rich natural gas resources to Germany first, and then transfer them to other European countries via the German trunk pipeline. At present, Russia mainly transports natural gas to Europe by land, via Ukraine, Poland and other Eastern European countries. However, this contract will expire on December 31 this year, and the renewal negotiations between Russia and Ukraine have not yet made any progress. Once the "Beixi -2" natural gas pipeline is officially put into operation, it means that Russia can stably supply natural gas to Europe even without the cooperation of Ukraine. However, it seems that Russia and Ukraine have reached an agreement on the "natural gas bill". According to Sputnik news agency & radio’s report yesterday (25th), Ukraine is going to sign a long-term contract with Gazprom to transfer natural gas before the end of this year, and the newly established Ukrainian natural gas transportation system operator will obtain the business license and qualification appraisal.
