Ouyang Zhenhua comprehends life and looks at fame and fortune after passing through the ＂gate of hell＂

　　Ouyang Zhenhua comprehends life and looks at fame and fortune after passing through the "gate of hell"

　　Qinghong picture

　　This year’s hit Hong Kong drama "Friends in a House" recently ended, with a maximum of 32 points of viewing, allowing the audience to see the majesty of the Hong Kong drama of the year, and also making "Rating Lucky General" Ouyang Zhenhua enjoy the taste of "old and red" again. Last night, on the stage of Jiangsu Satellite TV’s celebrity speech reality show "Tell My World", Ouyang Zhenhua had a rare insight into life. He admitted that after going through the gate of hell in 2013, he has regarded fame and fortune more and more lightly, and he hopes that everyone can cherish the time spent with their relatives.　　

　　Realize life

　　Cherish the time of company

　　Morning tea with my mother became a life-long pact.

　　Last night, on the stage of Jiangsu Satellite TV’s "Say My World", Ouyang Zhenhua rarely appeared as a speaker to tell his life insights. In 2012, for Ouyang Zhenhua, there was a sad experience that he did not want to recall. The death of his mother made him feel regret and regret. On the eve of her death, she often invited her son for morning tea, but Ouyang Zhenhua had a lot of scenes to shoot at that time, and he only slept for three hours a day, so he always shirked it. Unexpectedly, the sudden death of his mother made this morning tea with his mother an indefinite agreement. Ouyang Zhenhua said bitterly in the program: "Because I think my mother has always been healthy, I always think she has time. If you don’t see me today, there will be tomorrow, if you don’t see me tomorrow, there will be the day after tomorrow." Willing to tell this story, Ouyang Zhenhua confessed that his mother’s departure was a huge shock to him, "This mistake is made by many people. Many people work hard outside, hoping to earn more money to improve the life of their families and earn more money for their mother, but neglect to accompany their mother. She wants to have dinner with you and you will make excuses because you are too tired. When you have time, you hope to sleep for two more hours, thinking that you will accompany you tomorrow and the day after tomorrow, but you will stay with them." Ouyang Zhenhua uses his own story to make the audience pay more attention to the company of their relatives.

　　Rating lucky general

　　"Friends in a House" Enjoy being a junior

　　Fu Jiang has said for many years, both praise and pressure.

　　Ouyang Zhenhua has created many classic characters, including Chen Xiaosheng in "Senior Sister Tuo Gun", Peng Guodong in "Negotiation Expert", and Gao Yanbo in "Forensic Pioneer", who are nicknamed "Master Milk Killer". This year, a Hong Kong drama starring Ouyang Zhenhua, "Friends of a House", has become a hit again, with a maximum viewership of 32 points. The decline of Hong Kong dramas in recent years has also made the audience see Ouyang Zhenhua’s charm as a "lucky general". "Friends of a House" gathers senior figures such as Roland, Hu Feng, Liu Jiang, etc. At the age of 55, Ouyang Zhenhua is very proud that he has finally enjoyed the happiness of being a junior again. " In other scenes, because of my age, everyone regards me as the boss. But in this scene, I am still a child, Hu Feng, Sister Roland, Teacher Liu Jiang, and they are the boss. "Asked about the change in mentality in this drama, Ouyang Zhenhua did not change his funny nature," It’s very enjoyable, it’s very enjoyable, it doesn’t need to be said that’Ouyang Zhenhua’s failure is also Ouyang Zhenhua’s failure ‘. Putting the responsibility on them, I don’t have so much pressure anymore. "

　　Ouyang Zhenhua was a little shy when he said to the audience, "The lucky general has been saying for many years, and praise is also a kind of pressure. In fact, the lucky general has time to miss!" In Ouyang Zhenhua’s opinion, the success of each drama is not due to one person, "Other actors and staff in other positions have paid for it, not me alone."

　　As for the declining ratings of Hong Kong dramas in recent years, Ouyang Zhenhua believes that there are factors that contribute to the dispersion of audience viewing channels. "There are too many channels to watch TV. Pick up an iPad, pick up a mobile phone to watch, and you can also watch it on a computer. Now there are really fewer people watching TV at home.

　　Stick to TVB

　　Without TVB, there would be no Ouyang Zhenhua

　　Returning to TVB is like returning to your parents’ home. It’s nice to see many familiar faces.

　　In recent years, as the influence of Hong Kong dramas has been weakening, as the cradle of Hong Kong dramas and Hong Kong stars, TVB’s star light has also gradually dimmed, and many leading actors have left one after another, but Ouyang Zhenhua has always chosen to stick to it. For the departure of many colleagues, Ouyang Zhenhua confessed that there are two reasons: "TVB’s salary system has problems" and "there are more opportunities in the mainland, and it is easier to make money." Choosing to stick to it, Ouyang Zhenhua confessed that "without TVB, there would be no me Ouyang Zhenhua." He compared TVB to "my mother’s family". "When I go back to TVB to shoot, it is like returning to my mother’s family and returning to my alma mater. I am very happy to go back and see many familiar faces."

　　At the same time, Ouyang Zhenhua also admitted that filming in the mainland would make more money. He occasionally takes on some mainland dramas, but what he likes is not all money, but the exchange with mainland actors. "Due to different cultures and rhythms, the methods of acting are also different. For example, when acting in ancient costumes, mainland actors are more like ancient costume people than me. They raise their hands and move their feet, and the rhythm of their speech is really ancient costume. I have learned from them. But when acting in fashion dramas, they may not be as good as me. We communicate with each other very well."

　　Ouyang Zhenhua admits that the decline of Hong Kong dramas has something to do with the loss of talents, resulting in fewer and fewer authentic Hong Kong dramas. In his opinion, "Authentic Hong Kong dramas should be actors, middle-aged and young, and the audience is very familiar with them. They all have plays, rather than putting a play on one or two male and female protagonists." Ouyang Zhenhua believes that the success of "One Room Friends" is that it has the competitiveness of Hong Kong dramas. "In addition to me, the seniors of the older generation include Sister Roland, Hu Feng, Teacher Liu Jiang, and the new generation of actors. Audiences who can attract three generations of old, middle-aged and young people like to watch them, so the ratings are so high. The Hong Kong dramas that audiences look forward to are like this. Everyone has a play, and this is the authentic Hong Kong drama."

　　Through the gates of hell

　　Slow down and don’t be greedy for money

　　Nowadays, work, life, and rest must be balanced.

　　In 2013, Ouyang Zhenhua encountered a huge crisis in his life. He was sent to the hospital due to acute pneumonia. He was hospitalized for 12 hours and spent more than ten days in the hospital to recover. After passing through the gate of hell, he was also far away from the audience’s sight for a while, and recently the chance of appearing on the screen has also been significantly reduced. Today, Ouyang Zhenhua is quite dismissive of fame and money. "Money is money after all. If you can earn it back and put it there and don’t have time to use it, it’s just a blank piece of paper." Ouyang Zhenhua admitted that he had lived a difficult life, "I have tried it before, I was very poor, I am not afraid of hardship, and I can eat hamburgers every day. I am not greedy for money, I can eat enough and support my family, not every day I have to eat good things." That illness and hospitalization gave Ouyang Zhenhua a new understanding and understanding of life, "In the past, it was all about making money. After getting sick, I felt that I worked hard to earn so much money.

　　Ouyang Zhenhua is now deliberately slowing down the pace of work and will not shoot one movie after another. "I’m not in my twenties, not in my thirties, and it’s useless to shoot so much. If a person is tired, you come back with a lot of work, and it’s pointless to do it when you’re tired." So Ouyang Zhenhua is more willing to spend time enjoying life and feeling those pleasures that were often overlooked before.

　　Drama Bones Tell Drama Classics

　　Enjoy comedy with the most selective partners

　　I don’t mind going the comedy route all the time.

　　Ouyang Zhenhua’s comedic talent has been brought into full play in film and television dramas. He admits that he doesn’t mind taking the comedy route all the time, and he believes that directors and producers will not waste his comedic talent. However, as a famous comedian, Ouyang Zhenhua also "lost his feet" when he starred in "The Legend of Zhong Kui" in the mainland a few years ago. The ratings were very high, but because of its modern way of funny, it was also criticized for being too Internet. In response to these criticisms, Ouyang Zhenhua was very calm, "If you want to find a real Zhong Kui to hunt monsters, you should find someone with a more fierce face. If you want me to play it, you want Zhong Kui to have a little more humor, so they put a lot of elements on the Internet, and even let me wear sunglasses. These adults and children like it when they see it." As for whether he would be scolded or not, Ouyang Zhenhua didn’t care, "What we have in common is that we hope the audience will enjoy it."

　　Due to his popularity and cost-effectiveness, Ouyang Zhenhua is quite competitive in the mainland market, and his performance contracts are also continuous. As for the standard of receiving plays, he said that the most important thing is the partner. "The partner is that you act against him, and he also acts against you. If I really want to see if there is any spark between each other, I will accept it. I will read the script and watch the partner when picking a play. If these two aspects meet my requirements, it doesn’t matter if the money is a little more or less." (Xu Qinghong)

Don’t look at me small, don’t look at me cute, I’m still that fierce ＂little leopard＂ Jaguar E-PACE

The competition in the compact luxury SUV market has gradually become more intense after entering the second half of 2018. In addition to BBA, which took the lead in this market, the XC40 has also been launched recently, which is quite competitive. The significance is to face the current market segment. Of course, the British naturally did not idle, and also launched their own compact luxury SUV model – E-PACE, and this car has also completed the localization process and will be officially launched in China soon.

As the second SUV of the Jaguar family, it is also the only product with a horizontal engine in the current Jaguar product series. Although it is small in size and even a little cute, you can still tell from some family characteristics that this is a Jaguar.

E-PACE was originally defined as the first luxury SUV for young consumers, highlighting a strong sporty atmosphere is the most crucial, which is why E-PACE is said to be the younger brother of F-PACE, but in fact we don’t see much F-PACE shadow on E-PACE. On the contrary, the lines of the whole car are quite sporty, and the details are closer to F-TYPE.

The front face still had a distinct Jaguar family style. Although it looked simple, it was a big mouth grille with rounded corners and rectangles, but the front line of the car showed a downward posture, giving people a feeling that it was ready to explode, just like a leopard who was about to forage for food.

The headlights of the E-PACE have to be said to have the charm of a Jaguar sports car. The new car is equipped with LED light source headlights. Compared with the overseas version, the matrix LED headlights will appear in the domestic version as an option. The headlights of the upright design are derived from the design element of F-TYPE. After using this headlight design, the shape of the front of the car is more in line with the smart visual effect of this "little leopard". It has to be said that Brother G really admires these designers.

The side of the body is simple and smooth, and the roof line further reflects the sports genes of the vehicle. It starts from the A pillar to the roof part, and the transition is very natural, and finally it shrinks rapidly at the rear of the car. The shape of the window is also used in the design of a sports car, which is very dynamic, especially in the position of the tail. The upper half of the car looks very similar to our F-TYPE. The two-section waist line on the side, the front section continues from the upper wing of the fender in a gradually sinking posture to the rear of the B pillar, and the rear section starts to raise from the position of the rear door handle and expands to the sides, allowing the rear fender to become wider and more muscular, with a ready-to-go posture, like a hunting head.

The E-PACE is positioned as a compact SUV with a length, width and height of 4411 * 1900 * 1649mm, and the wheelbase is the same as the overseas version, both 2681mm.

The domestically produced E-PACE is still equipped with 20-inch high-specification wheels, and is paired with Pirelli P ZERO series sports tires, with a specification of 245/45 R20.

The rear line highlights the sense of compactness and sporty feeling. The two sides of the exhaust are very pleasing, after all, this symmetry makes people more comfortable to look at. The large-angled D-pillar and the sharp corner design of the trunk cover are very character, giving people a strong visual impact. The slender strip-shaped tail lights and the LED light band of the width indicator light make it more recognizable. At the same time, the size of the rear window is also narrow and flat, which looks more like a sports car from the rear side.

The interior of the E-PACE, how to say, it feels like a complete replica of F-TYPE. The overseas version of the full LCD screen has not been used in domestic models, and the traditional style of the instrument panel has been retained. The white text on the black background is clear and easy to read. The shape of the barrel is relatively large, and the three-dimensional sense is very strong. From the steering wheel, we can also feel a strong sporty atmosphere. The center console is equipped with a 10-inch color touch screen, with Incontrol system, supports multi-touch, and the familiar physical buttons are matched below, which is full of technology.

In terms of power, the vehicle is equipped with the Ingenium 2.0T engine independently developed by Jaguar, with two high and low power versions, the maximum power is 183kW and 147kW respectively, and the transmission system is matched with a 9-speed automatic gearbox from ZF. The suspension structure is a front McPherson independent suspension and a rear multi-link independent suspension.

G brother summary: As a compact luxury SUV, the biggest highlight of this car is the sports car design, which is why it does not look like the younger brother of F-PACE, but like an elevated F-TYPE, which also makes E-PACE in the future product positioning may have the opportunity to compete with competitors. With a younger and sportier design, E-PACE may really be able to open up a further segment of the compact luxury SUV market.

Unlike the well-known luxury brand BBA, Jaguar’s domestic road has not been very long, and consumers’ recognition of its luxury brand localization is still taking shape. As you can see, the domestic SUV market is fiercely competitive. The listing of Jaguar E-PACE will compete with GLA,,, etc. The future outlook of E-PACE cannot be said to be optimistic or negative at present. After all, the price is still unknown, so it is worth our continued attention.

＂Beidou＂ navigation empowers industrial development to accelerate (new economic direction)

Recently, the "Beidou Travel Application Innovation Plan" initiated by domestic enterprises was launched, and the Beidou innovative application represented by "lane-level navigation" will be popularized nationwide from the current 8 city pilots. It is understood that the plan also includes functions such as dynamic traffic light countdown and equal light status based on Beidou’s core computing power. It is an innovative service launched by Beidou high-precision applications for the public, which will help Beidou in the industrialization of traffic travel scenes.

The latest data shows that the total output value of satellite navigation and location-based service industry in our country has reached about 470 billion yuan; as of January this year, the global cumulative access to intelligent devices of Beidou space-time intelligent services exceeded 1.50 billion units; Beidou high-precision space-time service was called more than 170 billion times a month, and the service covered more than 230 countries and regions around the world; Beidou became the "standard" of smart phones and wearable devices, and Autonavi maps called Beidou satellites for more than 300 billion times a day.

Beidou, which is "easy to use in the sky and good on the ground", has moved from solving the problem of "presence and absence" to a stage of development of "higher accuracy, more credibility and better service".

Scale applications continue to expand

In the northwest region, planting cotton requires high-precision linear film mulching. If the agricultural machine cannot guarantee the linear accuracy of the operation, it will not only affect the quality of the film mulching, resulting in "film cutting" and rework, but also not conducive to the later topping, harvesting and other links. At the same time, it will cause land waste, reduce production, and affect the income of cotton farmers.

Now, with the Beidou navigation agricultural machinery automatic driving system, cotton farmers only need to set the operation width and other data to ensure that the agricultural machinery is accurate and straight operation, on-demand seeds, ridge mulching and other procedures are completed in one go, and the sowing efficiency and quality are greatly improved. "In recent years, the’Huinong Beidou navigation automatic driving system ‘we have built is widely used in tractors, rice transplanters, harvesters, plant protection machines and some specific self-propelled vehicles, covering the whole operation link of plowing, sowing, transplanting, ditching, plant protection, harvesting, flat ground, etc. The operation accuracy can reach 2.5 cm, and the cumulative operation area of the system exceeds 50 million mu." Shen Jun, chief scientist of Beijing Hezhong Sizhuang Technology joint stock company, said.

Application is the life infra of Beidou development, and agriculture is the key area of Beidou application. In recent years, Beidou has supported the rapid development of precision agriculture in our country, and the agricultural machinery automatic driving system based on Beidou system has exceeded 100,000 units/sets. This year, the No. 1 document of the Central Committee proposes to support the integrated application of Beidou intelligent monitoring end point and auxiliary driving system.

From transportation to agriculture, forestry, animal husbandry and fishing, from smart ports to power inspections, Beidou provides time and space services like water, electricity, gas and other public services, fully integrated into the infrastructure, deeply empowering all walks of life, and gradually entering thousands of households, generating significant economic and social benefits.

In the bustling business center of Beijing, shared bicycles with Beidou high-precision positioning function are parked in the "electronic fence", which is convenient for users to use and convenient for staff to dispatch and clear in time. "These shared bicycles are equipped with Beidou high-precision positioning modules, which can achieve sub-meter-level (less than 1 meter) positioning accuracy in open scenes." According to Dou Ke, head of hardware research and development of Meituan bicycles, in order to further improve the real-time and accuracy of positioning, they have upgraded the smart lock chip of shared bicycles from 2G to 4G, and equipped with more advanced sensors to make vehicle scheduling more orderly.

Data show that as of the first half of 2022, Beidou has been applied in more than 20 industries (fields). The total application of Beidou products has exceeded 15.50 million units/set. At present, the number of shared bicycles equipped with domestic Beidou high-precision positioning chips has exceeded 5 million, covering more than 450 cities; among the smartphones applying for network access in China, the mobile phone shipments that support Beidou positioning account for more than 98%.

"Today, Beidou has become an important spatiotemporal infrastructure in our country and has also played an important supporting role in the development of the digital economy. The spatiotemporal data generated by Beidou is the’blood ‘of the digital economy, and the massive data accumulated by the digital economy provides a vast world for Beidou applications. The industry and the public application field have created more and more digital application scenarios of Beidou, which has effectively expanded the breadth and depth of Beidou applications." Yu Xiancheng, president of China Satellite Navigation and Positioning Association, said.

Deep integration with emerging technologies

To communicate with each other and play an effective empowering role, data needs to have a unified temporal and spatial benchmark for "alignment". Only with accurate and reliable "space-time labels" can an accurate mapping of the real world and the digital world be achieved, and space-time-based perception, calculation and collaboration can be realized. With the combination of Beidou with artificial intelligence, big data, cloud computing, 5G communication, etc., Beidou applications are also extending to emerging technologies.

"Lane-level navigation" is a typical application of spatiotemporal intelligence, and it is also the product of the deep integration of Beidou and various emerging technologies. "The so-called’lane-level navigation ‘means that users can obtain extremely high-precision positioning provided by mobile navigation applications during driving. On this basis, when drivers need to change lanes, such as near expressway turning intersections or high-speed ramp,’ lane-level navigation ‘will provide more detailed lane-level voice broadcasts and action guidance." Liu Zhenfei, president of Autonavi Maps, introduced.

Chen Jinpei, chief executive of Qianxun Location Network Co., Ltd., said: "Technically, we observe the navigation satellite signal through the National Beidou Ground-based Enhancement System, and calculate the high-precision calculation engine to provide high-precision differential correction data to the end point of the mobile phone. After that, the mobile phone combines the original satellite observation data to complete the algorithm solution and obtain sub-meter positioning accuracy. Finally, the positioning and navigation application combines high-precision positioning maps to provide users with lane-level fine navigation guidance."

The successful application of "lane-level navigation" is inseparable from the all-round upgrade of positioning antennas, positioning algorithms, positioning chips, mobile phone maps and other technical elements. Since 2019, domestic enterprises have carried out joint research in a number of software and hardware fields, and made breakthroughs in reducing the power consumption of positioning antennas, real-time dynamic measurement technology algorithms, and deep adaptation of mainstream chip manufacturers.

In the opinion of Yang Changfeng, chief designer of Beidou satellite navigation system engineering and academician of the Chinese Academy of Engineering, China Beidou in the new era insists on application in development and development in application, and should follow the concept of "financial network, financial data, financial end point, financial service", expand and strengthen the new business model of "Beidou +" and "+ Beidou", vigorously shape the consciousness of the whole industry chain, create an innovative consortium, realize the integrated development of the industry, and strive to be the first in the world to open up the full link of high-precision positioning of mobile phones.

Yu Xiancheng believes that space-time information, positioning and navigation services, as important information infrastructure, can only continue to maintain the leading and integration of technology, promote the development of application services to depth and breadth, and better and more fully empower space-time.

Industrial development ushered in a period of opportunity

At present, the large-scale application of Beidou has entered a critical period, and it is also an opportunity period for the development of the entire Beidou industry. The "2022 China Satellite Navigation and location-based service industry development white paper" shows that in 2021, our country’s industrial core output value including chips, devices, algorithms, etc. directly related to the research and development and application of satellite navigation technology will reach 145.40 billion yuan, and the related output value driven by satellite navigation applications and services will reach 323.60 billion yuan. The number of enterprises and institutions in the field of satellite navigation and location-based service in our country is about 14,000, and the number of employees is over 500,000.

Yu Xiancheng said that the industrial application of Beidou is in a period of major change, and it is necessary to face the competition, find another way, and strive for advantages. By breaking through the key core technologies of the industry, we can promote the cross-integration of Beidou and digital technology, and promote the deep integration of Beidou and the industry.

Deqing County, Huzhou, Zhejiang Province, is a beneficiary of the development of the Beidou industry. It focuses on the advantageous industries of "Beidou Dixin", expands and forms industrial clusters such as "Beidou Dixin + artificial intelligence", "Beidou Dixin + general aviation", and gathers 2 provincial key laboratories, 2 provincial new R & D institutions, and 22 provincial high-tech enterprise R & D centers. It has successfully created the business card of "Geographic Information Town" and created considerable economic benefits.

"Promoting the development of the Beidou navigation and location-based service industry is an important means to accelerate the process of economic digital transformation and empower the development of the digital economy," Yu Xiancheng said. During the "14th Five-Year Plan" period, our country will further promote the standardization and ubiquitous development of Beidou, give full play to the role of Beidou as an independent time and space benchmark, and provide ubiquitous precise time and space information services, and truly realize the large-scale and market-oriented development of Beidou application services.

Rewriting our understanding of the early formation history of the Milky Way, scientists obtain the most accurate large sample of star age information to date

On March 24, Beijing time, the international scientific journal Nature published a major achievement in the form of a cover article by researchers at the Max Planck Institute for Astronomy in Germany in collaboration with Dr. Maosheng and Professor Hans-Walter Rix. Based onGuo Shoujing Telescope, a major national scientific and technological infrastructure operated by the National Astronomical Observatory of the Chinese Academy of Sciences(LAMOST) andESA Astrometry Satellite Gaia Telescope(Gaia) sky survey data, researchers have obtained the most accurate large sample of stellar age information to date, clearly reconstructing the formation and evolution of the Milky Way during its infancy and adolescence according to the time series, rewriting people’s understanding of the early formation history of the Milky Way.

The age of a star is one of the most difficult physical quantities to accurately measure in astronomy.

The beautiful and vast Milky Way in the night sky has aroused countless imagination and endless exploration since ancient times. Our Milky Way is an ordinary disk galaxy in countless cosmic islands. Like other similar galaxies, it has integrated hundreds of billions of stars over the past ten billion years. These stars are mainly distributed in the Milky Way’s halo and silver disk, which in turn includes a geometrically relatively thick disk and a relatively thin and more extended disk. However, when did the Milky Way’s halo and Milky Way disk form, and how did they assemble and evolve into today’s colorful galaxy?It has always been a scientific mystery that astronomers urgently need to solve.It is also the main scientific goal of a large-scale astronomical survey program for multiple ground and space telescopes around the world.

LAMOST publishes tens of millions of star spectra, becoming the cornerstone of the digital galaxy. The Gaia satellite launched by ESA provides maps of the positions and movements of 1.40 billion stars. This perfect combination provides astronomers with a unique advantage in tracing the integration and evolution history of the Milky Way. To Dr. Maosheng and Professor Rix based on LAMOST and Gaia data,High-quality data samples containing 250,000 subgiant stars were constructed and their precise ages were obtained.The age of a star is the most difficult physical quantity to accurately determine, and it can also be said to be one of the most difficult physical quantities to accurately measure in the field of astronomy.

Thanks to the LAMOST Milky Way Survey and other international sky surveys, obtaining the ages of large samples of stars has become a reality in the past few years. However, the typical age error of large samples of stars obtained by previous studies is 20% or more, and the star samples that achieve 10% age determination accuracy are very small, and the space and parameter range of the samples are also very limited. Using the LAMOST spectroscopic big data, the atmospheric parameters of 7 million stars were accurately determined in the Lush, and combined with the Gaia data, high-precision stellar luminosity and orbital kinematics parameters were obtained. 250,000 subgiant stars were selected from these 7 million stars, and their precise ages were determined.The average age accuracy of the sample is 7%.The metal element abundance coverage ranges from -2.5 (one-300th of the metal content of the sun) to 0.5 (three times the metal content of the sun), with a space coverage of 30,000 light-years. This is the first time that such a large sample of stars has been obtained within such a vast space and stellar metal abundance range of the Milky Way. It has successfully broken through the limitations of data and taken a landmark step for the study of the history of the formation and evolution of the Milky Way.

[The first "clear picture" of the history of the formation of the Milky Way]

Based on their motional characteristics and chemical DNA (elemental abundance), they divided 250,000 stars into two groups: those characterized by the formation of the Milky Way’s extended thin disk during a relatively dynamically quiet process, and those characterized by the formation of the Milky Way’s halo and thick disk during a dynamically violent turbulent process. The research team found that the ages of these two groups of stars, bounded by about 8 billion years, were equally clearly divided into two distinct groups. That is, in terms of time, the integration and evolution history of the Milky Way is divided into two well-defined stages, the early stage from 13 billion years ago to 8 billion years ago and the late stage from 8 billion years ago to the present. The early stage formed the Milky Way’s thick disk and halo, and the late stage formed the Milky Way’s thin disk.

The ultra-high temporal resolution allowed the research team to obtain a clear picture of the early integration and augmentation of the Milky Way: stars in the Milky Way’s thick disk have been forming since 13 billion years ago, just 800 million years after the Big Bang (corresponding to a cosmological redshift of 7). The oldest thick disk stars are even about 1 billion-2 billion years older than the stars in the Milky Way’s inner halo. The inner halo structure of the Milky Way is thought to be mainly caused by the collision of the Hundred-Handed Giant Enceladus Dwarf Galaxy (GSE) into the Milky Way and were accreted and formed in time. That is,The early thick disk formed 1 billion-2 billion years before the main stellar halo structure we see today, refreshing conventional knowledge of the galaxy’s early formation history.

After further investigation, Xiang Maosheng et al. also found that although the formation of the thick disk lasted for about 5 billion years from 13 billion years ago to 8 billion years ago, the metal content increased by 30 times. However, although the cycle lasted for 5 billion years, most of the thick disk stars formed in a concentrated explosion about 11 billion years ago. At the same time, they found that the merger of the dwarf galaxy GSE and the early Milky Way occurred about 11 billion years ago, which is 1 billion years earlier than previously thought. The two ages are highly consistent, which the research team believes is no accident, but strongly suggests that the star formation activity of the thick disk was significantly stimulated by the GSE impact event.

The gas that formed the thick disk stars was exhausted about 8 billion years ago, and the formation of the thick disk stopped. Around the same time, new gas began to gather from around the Milky Way into a thinner disk to form the Milky Way’s thin disk stars. The thin disk formation process continues to this day. At this point, a precise image of the formation and evolution of the early Milky Way on a timeline is presented, Nature journalThe reviewers’ evaluation of this result is the first to provide such a clear picture of the history of the galaxy’s formation.The Milky Way, as a representative of ordinary galaxies, is a key laboratory for our study of the formation and evolution of ordinary galaxies in the universe, which can help astronomers trace the fascinating stories that have taken place from the very early universe to today.

Gamblers ＂disguise＂ late-night theft, video surveillance restored

　　CCTV News: Not long ago, a mobile phone store in Kaili City, Guizhou Province, welcomed an unusual person in the early morning. This person was wearing a long white dress and carried an umbrella throughout the store. He looked rather strange. So what was the purpose of this person coming to the store? Surveillance video recorded the whole process.

　　Surveillance video from the store showed that at 1:26 a.m. that day, a person with long hair and a white dress appeared in the mobile phone store. Inexplicably, the person had been holding an umbrella after entering the mobile phone store.

　　The umbrella that opened the whole time completely blocked the face of the mysterious visitor. After the shutter door in the store was closed again, she took out a flashlight and began to observe around the store. So what did the visitor want to do when he came to the mobile phone store late at night with such an image?

　　After carefully observing the store for a long time, the person in the picture walks to the mobile phone counter, then she puts on the gloves she has prepared, and begins to put the mobile phone inside the counter into her own bag.

　　He didn’t panic when he committed the crime, only stole expensive mobile phones

　　The suspect was well-prepared and showed no sign of panic during the crime. At 1:46, the suspect, who had been in the store for a full 20 minutes, finally left the mobile phone store. It took nearly half an hour for the alarm device in the store to go off. The police rushed to the mobile phone store immediately after receiving the alarm.

　　After retrieving the surveillance video in the store, the police learned about the suspect’s crime process. But the crime scene was already in chaos, and the mobile phone counter was empty.

　　After the suspect entered the mobile phone store, he stayed in the store for nearly 20 minutes, but why didn’t the alarm device on the rolling shutter door go off?

　　The police investigation found that the power switch key of the alarm device was only available to the female clerk of the mobile phone store, and the female clerk happened to be on duty that night. Could the suspect in the video be the female clerk?

　　Umbrellas stand out, suspicious figures captured in video

　　Through investigation, the suspicion of burglary by the female clerk was ruled out. The police speculated that the alleged offender must have taken some method to destroy the alarm device of the rolling shutter door. So what was the identity of the suspect who hid behind the umbrella, and did she have other accomplices? Through the striking umbrella, the investigators successfully found the suspect wandering around the crime scene, and the case also took an unexpected turn.

　　The police retrieved surveillance video from the intersection near the crime scene and soon found the suspect’s figure.

　　The suspect did not take any means of transportation after the crime, but left the scene on foot with an umbrella. But what the police did not expect was that the suspect disappeared completely after turning at this intersection.

　　The cunning suspect walked all the way into the shantytown transformation area without surveillance probes in the middle of the night. The investigators had to gather all the surveillance video around the crime scene, but the suspect in a long dress never appeared in the surveillance video again.

　　The suspect couldn’t have disappeared out of thin air, but where did she go? If the police found the route she came from, could they follow the trail? After investigation, the police found that the suspect’s earliest appearance was still at this intersection.

　　The suspect arrived at the intersection near the crime scene an hour before the crime, so what was he doing when he showed up early?

　　The suspect wandered around the intersection for two full laps, and in these few wandering videos, the careful investigators made an unusual discovery.

　　From the appearance, the suspect is obviously dressed as a woman, so apart from his feet, what other characteristics of the suspect make the investigators suspicious?

　　So is it possible that the suspect is a man in disguise, and is the investigator’s judgment accurate?

　　The police conducted repeated research and judgment based on the surveillance video at the crime scene, and more doubts gradually emerged on the suspect.

　　Investigators analyzed that although the suspect was wearing a long dress, he was wearing a wig and his posture did not resemble that of a woman. Coupled with the suspect’s series of daring actions in the middle of the night, the police’s questions were gradually answered.

　　Dress up as a woman to confuse the investigation

　　Based on the analysis of a large number of details, the police suspected that the suspect was probably a man who disguised himself as a woman to hide his true identity and divert the attention of the investigation. Following this line of thinking, the police soon discovered something.

　　The police turned their attention back to the vicinity of the crime scene and found something strange. Shortly after the suspect disappeared, a suspicious man appeared.

　　The man suddenly appeared near the crime scene during a suspicious period of time, holding an umbrella in the weather when it was not raining. Such an unusual coincidence attracted the attention of the police handling the case, and what was even more puzzling was that the man actually changed taxis.

　　What is the purpose of changing taxis in place?

　　Surveillance video showed that the man did not leave immediately after getting out of the first taxi. He waited in place for less than two minutes and immediately switched to another taxi. So why did the man do this, and where did he go after changing taxis?

　　The police analyzed that the man was most likely the suspect wearing a long dress. After integrating relevant case information, the police also had a general description of the suspect.

　　Another mobile phone store was stolen, is it the same person?

　　If the suspect was in Cary, would he reappear? A few days later, the police received another report of a theft at a mobile phone store. All 30 mobile phones in the store were stolen in the early morning. Since there was no surveillance video in the stolen mobile phone store, the police could not immediately determine the time of the crime and the physical characteristics of the suspect. So are the suspects in these two cases the same person?

　　The police retrieved the surveillance video near the storefront where the crime occurred, and checked backwards from the time the shopkeeper left. After more than seven hours of screening, a suspicious man who appeared at the alley entrance entered the police’s field of vision.

　　The police analysis believes that the sneaky man is likely to be the suspect, and the repeated appearance of the man has also made the police handling the case more focused.

　　The same disguise method, find the suspect’s whereabouts

　　The suspect in both cases had the characteristics of wearing a wig and holding an umbrella. Could they be the same person? The police immediately began tracking the suspect’s whereabouts.

　　The suspects in the two cases had the same camouflage characteristics and disappeared in the same location. Faced with the highly overlapping characteristics, the police decided to conduct a combined investigation of the two cases and make every effort to find the suspects’ hiding places.

　　After the two cases were combined, the special task force police were divided into two groups and visited nearly 100 shops near the pryed storefronts in the two jurisdictions overnight to retrieve thousands of social video resources. Investigators worked tirelessly day and night to find the tracks of the suspects.

　　The investigator pushed the surveillance video all the way backwards, and after three days of continuous investigation, the figure that the investigator had been waiting for for a long time finally appeared.

　　The police arrived at the location of the surveillance video overnight, and there was only one residential building in the alley where the suspect appeared. After repeated communication with the landlord, the police retrieved the surveillance video in the building overnight.

　　After questioning the police, it was learned that the alleged offender should be in the house at the moment, and the police decided to immediately arrest the alleged offender.

　　The alleged offender suspect Yang, 47 years old, Kaili. In the face of the sudden appearance of the police, Yang’s performance is extremely calm.

　　Is Yang really an ordinary part-time worker as he said? After the investigator searched the rental house he rented, he made a significant discovery.

　　Search for female products, a few pieces of paper reveal secrets

　　Faced with some items found by the police, Yang said that all the wigs, high heels and other women’s products in the house belonged to his girlfriend, and he had never used them himself. However, the appearance of a few letter signs soon changed Yang’s attitude.

　　The police found that the content written on these sheets of paper was all related to theft, detailing the characteristics of the store where the suspect wanted to steal and the detailed process of planning the crime.

　　In the face of a large number of facts, the alleged offender Yang finally admitted to the fact that he stole two mobile phone stores, so how did he embark on this illegal road?

Alleged offender

Alleged offender

　　It turned out that in 2009 the alleged offender Yang had been jailed for kidnapping, after he served his sentence and was released from prison, Yang’s mother gave him tens of thousands of yuan to let him go to business, but did not expect that in just a few months Yang became addicted to gambling.

　　Yang wanted to double his money by gambling, but not only did gambling fail to make him money, but it also caused him to owe more than 100,000 yuan in gambling debts.

　　Under the pressure of debt collection, the alleged offender Yang finally decided to steal the mobile phone store.

　　Yang successively visited six mobile phone stores in Kaili City. After grasping the characteristics of the store, Yang wrote down the key information on paper and planned the crime in detail.

　　In the process of continuous monitoring, Yang purchased a variety of crime tools one after another, and in order to better disguise himself during the crime, Yang also purchased a large number of women’s products.

　　In this way, after a series of preparations, the alleged offender Yang committed two crimes in a short period of time.

　　At present, the alleged offender Yang has been approved for arrest, and all the stolen mobile phones have been recovered by the police.

＂Adventure Life＂ was well received： variety shows are not only entertainment, but also social care.

　　Douban 9.1 points, the star documentary reality show "Adventure Life" updated in Tencent video every Tuesday is a rare "explosion" in recent domestic variety shows. Although there are stars’ blessings, this program does not have the impetuousness of game variety, nor does it have a cursory tour of travel variety.

　　The audience saw the other side of the star in the program. For example, the hostess Xiao S shed tears in the face of the hunted elephant, and the literary actress showed her early wisdom in the process of pursuing the tornado in spring and summer. The singer Pu Shu showed her sensitivity and casualness in the program. Behind the show, there is also an unconventional team. They have never produced variety shows before, and they are more focused on the creation of documentaries. It is precisely this unconventional operation that has brought a clean stream to the domestic original variety show.

　　Program settings cannot be defined.

　　Rejected by many stars

　　As the producer of the documentary "The Train on the Way Home" and "A Hard Work", Zhao Qi, the general director of "Adventure Life" and his studio have been making documentaries before, and it is actually a coincidence that they contacted the project of "Adventure Life". Aya, the host, wanted to do a unique variety show and find Zhao Qi’s team. After repeated discussions, the two sides came up with the planning scheme of Adventure Life. When the plan was shown to Tencent, I also encountered the question "What kind of program is this?". After all, according to the original setting, Aya just made 10 trips with 10 star friends on the show.

　　According to the operating experience of past travel reality shows, flowers and teenagers, for example, focus on showing the relationship between stars when they travel overseas, while Fast Forward launches a game reality show overseas with the nature of competition, but Adventure Life does not travel or compete, and no one can imagine what form it will be. "Including when communicating with artists, many artists wondered what we were going to do, and some people refused our invitation because of this uncertainty." Zhao Qi revealed that the guests invited by the current program are actually very adventurous and willing to make such an attempt under the premise of uncertain program form.

　　"We believe that people will start to change at a certain moment because of a special opportunity. This change may be because you went to a certain place, or because you met someone. In our view, this change is a kind of life ‘ Adventure ’ 。” Zhao Qi said that based on this presupposition, the film crew also prepared various experiences for artists, such as chasing tornadoes in the United States, climbing mountains, watching elephants in Africa, and experiencing music therapy in hospice care institutions. To sum up, it is "don’t go to tourist attractions, communicate and communicate with local people as much as possible". This arrangement also had a wonderful chemical reaction with artists. For example, Pu Shu, who is sensitive and introverted, repeatedly refused to shoot, but opened himself after riding a motorcycle, and the contrast between before and after also revealed his true personality.

　　Documentary team shooting

　　Present the artist’s true feelings

　　Adventure Life includes 10 artists and 10 destinations in advance, and each journey is also estimated to be an overseas trip of 6 to 7 days. According to the configuration of conventional variety shows, this is a large variety team that needs 100 people. However, Zhao Qi revealed that the filming still continued the configuration of the documentary film crew, and with the photographer team, there were more than 20 people.

　　In terms of shooting methods, the team also insists on adopting the documentary mode of small machine and small team. Compared with the habit of shooting dozens of cameras in variety shows and often clearing the field, the shooting of Adventure Life is still "small and beautiful" in the form of workshops. "The documentary team hopes to reduce the involvement of the camera as much as possible. Even when shooting outside, we will not let the camera follow too close, so as to make the artist’s state more relaxed and natural." Zhao Qi said that according to the experience of documentary shooting, if the artist can finally ignore the existence of the lens, it will be considered as a qualified shooting effect.

　　When communicating with the artists’ team, the film crew will also ask the artists to reduce the number of staff accompanying them when shooting overseas as much as possible, and at the same time require a shooting cycle of at least 6 to 7 days. "The smaller the number of artists, the more likely an artist is to step out of his comfort zone. If he returns to his small circle as soon as he finishes filming, it is actually difficult to really form a close relationship with the shooting team." Zhao Qi revealed that if the team protection is relatively weakened, artists will have a stronger dependence on the film crew and their presentation in the film will be more realistic. A shooting cycle of about a week also helps to accelerate the establishment of trust between artists and the film crew. "It is obviously difficult to really experience the so-called life and there will be no special feelings when you leave by plane just for two or three days like a general variety show."

　　Focus on social public sphere

　　Want to touch the audience

　　In the title of "Adventure Life", there is such a passage, "The earth, 510 million square kilometers; Humans, 7.04 billion. When we stare at the world, the world stares at us. When we met them, we also met ourselves. Only starting is the beginning of everything. " The audience "Sister Dog Flower" said that it was this passage that made her feel that this program was different, "Haruki Murakami said, ‘ This happens from time to time in my life, and something happens. The light of that moment is like a flare, which vividly illuminates the surrounding scenery that is usually invisible to the naked eye. ’ When I watched Adventure Life, my feelings were nothing more than this. "

　　"This program shows the three-dimensional sense of the world and the multifaceted nature of human nature. The guests of the program are trying new explorations and feeling new adventures every moment, and as an audience, the same is true." For Zhao Qi, this kind of program feedback is exactly what he pursues. "We always think that variety shows are entertainment, but there are other possibilities besides entertainment." In his view, as an extremely important social resource, stars’ leading participation in activities will naturally generate attraction. "Wouldn’t it be better if we used this attraction to focus on social public areas and attract people’s attention to those areas with more social significance and value?"

　　He made such an attempt in "Adventure Life", in which the singer Mao was not easy to participate, and the program group arranged for Mao to go to a hospice care institution in Taiwan Province to experience the help of music therapy to dementia patients and severely disabled people. "We have all heard of hospice care, but few people know what kind of institution this is and how the old people live in it. After the broadcast of this program, I believe that many young people can learn about this institution, perhaps because of this program to start contact with hospice care. " Zhao Qi said that the film crew doesn’t set specific goals, but they are more concerned about touching the audience through the artist’s experience, which may help the society pay attention to related topics.

　　"We are really not a traditional variety show team, but this is not our disadvantage and shortcoming." Zhao Qi bluntly said that as a documentary team, they have their own image creation methods that they are good at, and they have more cultural expectations different from variety shows, which is also the root of the completely different features of Adventure Life. "This may be the insistence of a documentary, but someone has to do this kind of thing." (Reporter Li Xiazhi)
