TFBOYS old materials have been turned over, and Christina has become a "social cow". Who is boosting the entertainment "archaeological fever"

　　Recently, the video of Christina years ago was dug up and suddenly turned into a "social cow", which attracted attention. At the same time, the early video of TFBOYS member Karry has also been turned out, and "this child has a stalk since he was a child" has become a topic, while Gaowa Siqin’s ancient early video has brought fire to "sheep placenta theory".

　　This wave of trends, known as "idolize", has provided endless resources for the second creation of major platform users, the topic speculation of marketing numbers, the setting of platform entertainment topics, and so on, just like the popularity of old dramas in recent two years. Old topics are discussed, old terrier is played, and the entertainment "archaeological craze" becomes a new traffic password.

　　Look, how much fun the previous stars had.

　　Recently, a draft clip of Happy Boys 2013 was turned out by netizens, and actor Christina became the focus of attention. At the scene of the program, Christina made a gesture of kneeling on one knee and putting his right hand on his chest to the then player Oho Ou, and shouted: "Tonight, I am God V, but at this moment, you are my God!" Faced with this scene, the contestants on the stage were embarrassed with He Jiong and Wang Han, and the audience broke into shouts. As a guest of "V God" invited by the program, Christina can directly canvass for his favorite players. Because the "Fast Man" final was still broadcast live, how to canvass and what to say could not be rehearsed in advance. Christina’s more dramatic "confession" canvassing may also be improvised on the spot, but it has achieved a very "explosive" effect.

　　Christina plays mature female roles in TV series. She can be so open on the variety stage, showing her other side and making the program full of effects. The moment when this program was very effective, it was cut out by the current netizens alone, and it quickly became a scene of "going out of the sky" in Christina’s career under the trend of "seeking novelty" and playing tricks. Christina’s "black history" is on fire, and Christina also has the titles of "social cow" spokesperson and "the first madman in entertainment" in the competing comments, spitting and pattern imitation of netizens. Some netizens said that Christina’s "magic sound is in my ears and I will never forget it in my life". Some people continue to play tricks, and various lip-synching short videos of "You are my God" appear. Some people imitate the tone of "You are my God" with erhu, guzheng and piano …

　　The reason why Christina’s ancient video can stir up a wave of discussion and imitation is because it coincides with the current popular craze of embarrassing stars to learn to make stalks. The more unexpected, subversive and even outrageous scenes the stars are, the more sought after by netizens. The stars in this scene will quickly become the imitation resources of self-media, marketing numbers and secondary creators, and become their funny objects and funny objects. In order to watch and click, these netizens will actively explore such videos and actively imitate and arrange funny scenes of stars. In this process, the star embarrassed to learn to become a network traffic password.

　　From the netizens’ playing the "sheep placenta theory" in March, we can also see how varied the current entertainment "archaeological fever" is. In 2012, Gaowa Siqin and a star promoted the TV series "Mother, Mother". During the interview, a star suddenly broke the news that Gaowa Siqin had hit the sheep placenta, and asked Gaowa Siqin if the skin had started after hitting the sheep placenta. The embarrassment of this scene and the strangeness of the scene are really rare in star interviews. Ten years later, everyone pays attention to this video again. It is not about who is right and wrong, who has high emotional intelligence and who has high acting skills. Instead, it is completely regarded as the hottest object of online play. "Is this ok?" "Is the skin unfolded?" "From the inside out" has become a buzzword. Millions of clicks of sheep placenta imitation makeup, sheep placenta imitation show, sheep placenta ghost song and so on constitute "sheep placenta science", and netizens, netizens, ghosts and animals, etc.

　　This interview between Gaowa Siqin and a star was played like this, which I believe was unexpected by the parties. At the moment when the media is popular and the entertainment marketing number "eats dry and wipes clean" the entertainment news, I believe that no star dares to show his true nature in this way, and he can no longer provide more imitation resources for entertainment gossip lovers to dig deep and create again. Under the combination of various factors, it has become a trend to "turn over old scores" in idolize and "archaeological" in idolize.

　　Platform topic setting and netizens’ collective carnival

　　The current "archaeological craze" for entertainment of movies, variety shows and star news may be related to the lack of entertainment activities such as the suspension of the draft, the suspension of concerts, the reduction of artists’ activities and the withdrawal of movies. In this wave of craze, we can vaguely see some kind of guidance and setting of entertainment hot topics and entertainment topics. Media platforms and media creators play a certain role in the "archaeological fever" of entertainment, forming some kind of collusion.

　　When this round of "sheep placenta theory" was the most popular, the number of clicks of a makeup imitation video on a single platform quickly exceeded 6 million, and different forms of makeup imitation videos, spit videos and popular science commentary videos blossomed everywhere in the same period of major platforms. The content related to "sheep placenta theory" is even more hot search lists of their respective media platforms, and it has formed a lively situation that "big UP masters imitate stars, small UP masters imitate big UP masters" and "top flow" of each platform cooperates with each other to harvest traffic. In the big explosion of "sheep placenta science", all platforms have achieved a win-win situation of collective momentum and collective harvest traffic. There is an element of network follow-up. A large area of follow-up has revived "old terrier" and "Laogua", but this multi-platform and large-area "resurrection" is related to the hot search topic setting and guidance of the platform, as well as the emphasis on traffic and overweight.

　　Recently, hot search topics such as "Karry sings English songs well" and "Karry’s child has a stalk since he was a child" often appear on a platform. The video of Karry performing in a shopping mall when he was a child was frequently searched, and Karry Jr. was labeled as funny. The video of "Magic Castle" sung by TFBOYS members in their third anniversary concert was also widely circulated. Fans and netizens are delighted with the "archaeology" of TFBOYS. If you look closely, you will find that these nostalgic entertainment topics are frequently searched, which is directly related to the setting and guidance of entertainment topics on a platform "Today of that year". It is understood that the functions of "Today of that year" and searching by time launched by a certain platform last year have become important tools for fans to "turn over old scores" in idolize. The person in charge of the entertainment section of the platform also said that the "archaeological" content of the stars will indeed be pushed recently, and the marketing number of the whole network is sending the stage videos of the stars in the past.

　　On the other hand, the platform is also contributing to the popularity of "archaeological" videos in Christina. The hot search topic "You are my God" has been on the list for 14 hours. "You are my god imitation contest" even stayed on the hot search list of a short video platform for 37 hours, forming a powerful topic effect and traffic harvest. Since the second creation of UP from the media, I am busy creating videos, and the platform is pushing the stream. Netizens are crazy about eating melons, forming a craze.

　　Looking at the whole network, not only the "archaeological craze" for entertainment stars has become a craze, but also the influence of the platform can be seen in the recent "Zhen Xuan craze" and "old drama craze". Behind the "old drama fever" from the media and short video platforms, the long video platform relies on the lagging publicity of exclusive copyright dramas, the new development of old dramas to increase the popularity and capture traffic. For example, the number of Youku users with exclusive copyright in Empresses in the Palace has reached 267 million, and according to the survey, the favorite TV series of users on this platform is Empresses in the Palace. Empresses in the Palace is beautiful, but it contracts "hot search" every day, which may have a lot to do with the marketing and entertainment agenda setting of the platform.

　　The essence of entertainment "archaeological fever" is still a kind of entertainment carnival from the media, in which the platform is boosted and the flow is harvested, which together form a complex situation of collective carnival.

　　On the morning of November 12th, China Men’s Soccer Team conducted the third outdoor training in Shenzhen Universiade Center Stadium. During the training, China Football Association President Song Kai appeared at the training site. It is understood that Song Kai visited the national football team that is preparing for the 36-strong World Cup preliminaries by going to Shenzhen to investigate youth football. After talking with some of the team veterans, Song Kai encouraged the team to "unite as one and play the true spirit of China football".

　　On November 11th, Song Kai, President of China Football Association, appeared in Shenzhen. Accompanied by relevant leaders of Guangdong Sports Management Department and Shenzhen Football Management Department, he went to Shenzhen Youth Football Training Base in Guangming District, Shenzhen to conduct research on the contents of youth training.

　　Song Kai’s visit to Pengcheng also has an important task, that is, to visit the China men’s soccer team who are preparing for the first two rounds of the second stage (Top 36) of the 2026 World Cup preliminaries in Asia. According to the reporter of Beijing Youth Daily, after the investigation of youth training came to an end, Song Kai made a special trip to the resident hotel of the national football team and had an exchange with some old players including captain Wu Xi. In the process of heart-to-heart, Song Kai also expressed China Football Association and his expectation and trust attitude towards the national football team, especially the old players, hoping that these old players who have played in many major competitions for their country can play a leading role. In fact, in the process of internal work exchange, Song Kai has always stressed that the old players are very important to this national team. China must give full play to the mentoring role of the old players when they attack the World Cup.

　　On the morning of the 12th, the national football team went to the auxiliary field of the Universiade Center for outdoor joint training. When the training process was halfway through, Song Kai and his party appeared at the training site. After the training, Song Kai made a speech on the spot for less than 5 minutes. Song Kai encouraged the players that the task of attacking the World Cup is great. The China Football Association and himself will always trust and support the team, hoping that the players can lay down their burdens and unite to play the true spirit of China football. Song Kai also told the team members to pay attention to their health and look forward to the team’s victory in the first round of this World Cup.

　　It is reported that in order to avoid adding pressure to the national football team, Song Kai will not go to the away game to supervise the first match of the top 36 national football team against Thailand. However, he still plans to go to Shenzhen to watch the key game of the national football team against the South Korean team at home on the 21st of this month to cheer for the national football team.

　　[PConline first evaluation]This year’s DIY hardware market is not very friendly to gamers. First of all, the mining tide at the beginning of the year led to the soaring price of graphics cards. Finally, the mining tide faded and Intel’s so-called 14nm capacity crisis occurred, and the price of CPU began to soar. The price of NVIDIA’s new RTX graphics cards was even more expensive. When the price of Intel CPU soars, we can choose AMD Ryzen processor, which is more affordable, as a substitute. Then, when the price of NVIDIA soars, we naturally hope that AMD can come up with better new products to make us feel refreshed. It’s not, RX 590 is coming.

　　Today, AMD officially released a brand-new RX 590 graphics card. Today, let PConline Jia Xiaobin take you to see if this new graphics card can undertake the sacred task of saving the majority of DIY players.

　　Under normal circumstances, there will be a large section of technical analysis about the product in the first test, but not this time, because the RX 590 will not have too many innovations, and we can summarize it from several aspects.

　　First, the graphics card still adopts Polaris architecture, and the core code is Polaris 30.

　　Second, the number of stream processors for graphics cards is still 2,304, which means that the specifications of RX 590 are the same as those of RX 580, which may not be in line with our cognition. After all, the specifications of AMD graphics cards will be improved compared with those of ~90 models, but this is the reality.

　　Third, the graphics card uses Grofonde’s latest FinFET 12nm, which should be the same technology as the second generation Ruilong. Judging from the performance of the second generation Ruilong,GF’s 12nm process can improve the overclocking ceiling of the core and reduce the power consumption of the same frequency.Let’s see if this is the case in the following test.

　　Fourth, the video memory of the graphics card is 8GB, and the GDDR5 video memory is still used.

　　From the comparison of the following tables, we can see the difference between RX 590 and RX 580 and RX 480 more intuitively.

　　Parameter comments:Because the Polaris 20 core used by RX 580 is already a complete body of Polaris architecture, there is no room for increasing specifications. Therefore, the adoption of Polaris architecture by RX 590 also means parameters such as stream processor and texture unit of graphics card.And RX 580 are exactly the same., but using a better process to Refresh the core, so the improvement of frequency and the change of power consumption have become the biggest differences of RX 590, which are also the focus of this evaluation.

　　This is the same routine as the upgrade of RX 580 compared with RX 480. Simply speaking, RX 590 is a duplicated version of RX 480.The difference is that RX 580 uses the same process as RX 480, but the process is more mature and allows AMD to overclock, while RX 590 uses a brand-new 12nm process, and the frequency progress is also relatively large.

　　To be honest, Xiaobian is still a little disappointed with the parameters of RX 590. Although the frequency of RX 590 is 205MHz higher than that of RX 580, it is about 15%, but when the graphics card specifications are unchanged,With the increase of frequency, the performance of graphics cards will increase less and less.Just like the so-called barrel theory, how much water can be loaded depends on the short board of the barrel.

　　The starting price did not increase, and it remained at the same 1999, which is good.

　　Considering the huge performance gap between GTX 1070 and GTX 1060, it seems impossible for RX 590 to challenge GTX 1070 this time. Is this the case? Don’t worry, the later on-board measurement can solve your doubts.

　　This time, RX 590, like RX 580, is also the first launch, and it is directly released in a non-public version. This time, we also got a non-public version of the sapphire RX 590 Ultra Platinum Aurora Special Edition, which is also the protagonist of this RX 590 evaluation.

　　The appearance of the graphics card is basically the same as that of RX 580 Ultra Platinum Aurora Special Edition, with the ancestral "gas stove" shape, but the graphics card is dominated by light blue color matching and decorated with a little gray, which makes the square graphics card look very energetic and no longer rigid.

　　The video card fan is an LED fan with a diameter of 95mm, and its blades are transparent, which makes it easy to transmit light when starting. At the same time, the video card fan is designed to be detachable, so consumers can replace it themselves when they don’t like light pollution or the fan is faulty.

　　There will be a sapphire RGB belief light at the top of the graphics card, which supports 6 modes.

　　The external power supply of the graphics card is designed as 8+6pin, which is consistent with the RX 580 Ultra Platinum Aurora Edition.

　　The thickness of the graphics card is about 2.2 slots, and it is filled with very dense fins, which is a good material in the mid-range graphics card, which also shows that the heat of the graphics card should be considerable.

　　The graphics card also has a large area of backboard, and the backboard is mainly light blue. The large area of backboard can not only play a protective role, but also assist the graphics card to dissipate heat.

　　The graphics card also has two BIOS, and the mute BIOS is close to the video output interface.The core frequency is 1545MHz consistent with the public version, the video memory frequency is 8000MHz, and the other side is the game BIOS, with the core frequency of 1560MHz and the effective video memory frequency of 8400MHz.

　　The video output interface of the graphics card is designed as 2 HDMI+2 DP+1 DVI.

　　It is not difficult to disassemble the graphics card. Just unscrew all the screws on the back plate with a moderately sized Phillips screwdriver. The heat dissipation material of the graphics card is still good. The part in direct contact with the GPU uses a pure copper base, and the parts in contact with the video memory and power supply are also covered with heat conduction stickers.

　　The graphics card uses 4 heat pipes, 2 8mm and 2 6 mm.

　　Next, look at the PCB board of the graphics card.

　　This is the high-definition codeless recent photo of Polaris 30 core.

　　The core size is about 14 mm * 18 mm.

　　The memory comes from magnesium light, with a single capacity of 1GB, a total of 8.

　　The power supply of the graphics card is designed as 6+1+1, and the fourth generation black diamond inductor and 16K black gold capacitor are used to ensure the stability of the power supply of the core and video memory.

　　The disassembly of the graphics card is here. Let’s carry out the on-board measurement that everyone is most concerned about.

　The platform collocation of graphics card test is very important. The following is the test platform used in the initial evaluation of RX 590.

　　In order to ensure that the CPU and memory of the platform will not become bottlenecks, we all try to use high-standard hardware. Although the i7-8700K is the flagship of the previous generation, it is more than enough to squeeze out the performance of the mid-range graphics card, and the memory of 3200MHz is also luxurious for the mid-range installed configuration.

　　The above is the information displayed by the sapphire RX 590 Ultra Platinum Aurora Special Edition in GPU-Z. Because GPU-Z has not been updated, some information is displayed incorrectly, such as the process or the 14nm process.

　　Because the sapphire RX 590 Ultra Platinum Aurora Special Edition uses mute, the frequency of the graphics card is exactly the same as that of the public version.Therefore, we also use silent BIOS for testing, which can be directly regarded as the performance of RX 590 public version.

　　GTX 1060 uses the public version. There is nothing to say. RX 580 uses ASUS DUAL RX 580 O8G.Because its frequency is 1360MHz, it is very close to the public version, and its performance is about 1~2% different from that of RX 580, which can basically be regarded as RX 580 public version..

　　The GTX 1070 was close to production stop a long time ago, so it was difficult to find this graphics card, and the evaluation room could only find this ASUS DRAGON GTX 1070 TOP8G. It is worth noting that the frequency of this GTX 1070 has reached 1671MHz, and the nominal maximum frequency is 1874MHz (of course, the actual BOOST frequency of the N card is definitely much higher than this), which is 11% higher than that of the public version.It is one of the strongest GTX 1070 non-public versions, and its theoretical performance is 6~8% stronger than that of GTX 1070 public version.Of course, the power consumption of the graphics card will be about 40w higher, so you want to know the performance gap between the RX 590 public version and the GTX 1070 public version in the following test.Properly reduce the performance of GTX 1070 in the test..

　　The situation of RX VEGA 56 is similar. We only found the sapphire RX VEGA 56 ultra-platinum limited edition as the test graphics card, but we used the silent BIOS of the graphics card.The performance is 2~4% better than that of RX VEGA 56 public version.The power consumption is about 30w higher.

　　First, the theoretical test of 3DMark, in addition to the two commonly used tests of FireStrike Extreme and FireStrike Ultra, there is also the Time Spy of DirectX 12 benchmark performance test for game PC launched by 3DMark. At the same time, in order to ensure the beauty of the chart, the name of the graphics card is omitted.

　　Summary of theoretical performance test:In the end, sapphire RX 590 is 12%, 14% and 11% stronger than ASUS RX 580 in the three tests, which is not a big improvement, but the gap is not small.

　　Compared with the GTX 1060 public version, it is 17~22% stronger, and compared with the ASUS DRAGON GTX 1070 TOP8G, it is about 22~28% behind, not to mention the sapphire RX VEGA 56 ultra-platinum limited edition.

　　Simply put, the theoretical performance of RX 590 should be just inserted between GTX 1060 and GTX 1070..

　　However, 3DMark can only measure the theoretical performance of the graphics card after all, and how many game frames the graphics card can bring is what we are most concerned about. Let’s measure the game below. There are 6 games we tested, including the latest and most popular 3A masterpieces Assassin’s Creed: Odyssey, Tomb Raider: Shadow and Extreme Racing: Horizon 4, as well as the game Singularity Ashes, which Microsoft used to promote DX12′ s own operation. The test results are very representative.

1. Tomb Raider: Shadow

　　Unconsciously, Laura has been with us for 20 years, and has developed into the 11th generation. Today, she has been able to support all kinds of latest, true and most eye-catching graphics technologies.

2. Extreme Racing: Horizon 4

　　As an old racing game, forza motorsport series is very famous. This series is made by Playground Games. The open world of this series is the biggest highlight different from the original series. It is known as "the best racing game in this century", and its picture quality is exquisite and optimized. Netizens who like racing must not miss it.

3. Assassin’s Creed: Odyssey

　　Assassin’s Creed: Odyssey is the 11th work in the Assassin’s Creed series, which was created by Ubisoft. In the game, players will return to ancient Greece and play a mercenary with Spartan ancestry who was sentenced to death by his family, thus starting an epic journey from a young abandoned man to a legendary hero. The plot design and image quality of the game are very brilliant, and it is a strong competitor for the best game of the year.

4. "Singularity Ash"

　　Microsoft’s personal work to promote DX12 API perfectly supports all the effects of DX12. Benchmark optimization is in place, and it is also very suitable for testing DX12 performance and graphics performance of graphics cards.

5. Strange Squad

　　"Strange Squad" is also a new game that went on the market only at the end of August. The PC started and supported DX12 perfectly, and the Steam list was highly rated.

6. "Whole Territory Blockade"

　　It is also a classic masterpiece created by Ubisoft, which is all the rage. It is said that the second one will come out soon, and then our evaluation room will test the game with the new version.

　　Summary of game evaluation:The improvement of RX 590 compared with RX 580 is obvious. At 1080p, it can generally improve about 7 or 8 frames. In many games, it can be improved from "playable" to "fluent 60 frames", which is not bad. We summarize the performance of five graphics cards in six games under 1080p, and get the following chart.

　　At 1080p, sapphire RX 590 Aurora Special Edition can lead GTX 1060 public edition by about 14% and ASUS DUAL RX 580 O8G by about 13% on the frequency of public edition. However, the RX 590 is still about 25% behind the ASUS DRAGON GTX 1070 TOP8G, and about 35% behind the sapphire RX VEGA 56 ultra-platinum limited edition.

　　When it comes to 2k resolution, because A card has always been willing to allocate video memory, the bandwidth of video memory of A card at the same level will be larger than that of N card. The higher the resolution, the better the performance of A card in comparison, and this time is no exception. At 2K resolution, RX 590 is 20% ahead of GTX 1060, and about 23% behind ASUS DRAGON GTX 1070 TOP8G.

　　Since it is impossible to test the power consumption of a certain hardware separately, the following are all the power consumption of the whole machine, which are three application scenarios. The game is fully loaded with the peak power consumption of the whole machine in the 11》Benchmark process of Tomb Raider 11, and the graphics card is fully loaded with the peak power consumption of the whole machine in the 3DMark stress test.

　　Power consumption has always been the most disadvantage of A card. From the results, A card really can’t reach the excellent energy efficiency ratio as N card, and the gap is not small. The platform power consumption of RX 590 is about 100w higher than that of GTX 1060, and 30~40w higher than that of high-frequency GTX 1070.

　　We mainly look at the new technology to make the new AMD graphics card compare with the old one. From the results, the power consumption of RX 590 with public version frequency is still higher than that of RX 580 with public version frequency, which is about 40 W. Does this mean that GF’s 12nm process is useless?

　　We also found the sapphire RX 580 ultra-platinum limited edition as a comparison. The sapphire RX 580 ultra-platinum limited edition is the highest frequency RX 580, reaching 1450MHz. From the results, the platform power consumption of sapphire RX 580 Ultra Platinum Limited Edition is basically the same as that of sapphire RX 590 Ultra Platinum Aurora Special Edition, and even the RX 590 platform is slightly lower.However, the frequency of the sapphire RX 590 Ultra Platinum Aurora Special Edition is 95MHz higher.

　　That is to say, GF’s 12nm technology can increase the power consumption of graphics cards by about 100MHz.Looking at the new technology in this way is not a gimmick, it is indeed an improvement. In fact, we probably know how much progress GF has made at 12nm from the performance of the second-generation Ruilong compared with the first-generation Ruilong, and the GPU core is larger, which makes it more difficult to improve the frequency. We can only say that the performance of this process is in line with Xiaobian’s expectations, and there is progress, but the improvement is not great.

　　Let’s take a look at the performance of sapphire RX 590 Ultra Platinum Aurora Special Edition in terms of temperature, noise and stability. The test performance of this graphics card is closely related to the design and manufacturing skills of sapphire graphics cards.

3DMARK stress test results:

　　In the 3DMark stress test, 97% passed, and finally the graphics card passed the test with a score of 98.6%, indicating that the stability of the graphics card is no problem. In the stress test, the highest instantaneous frequency of the graphics card is 1514MHz, which does not reach the nominal value of 1545. It may be limited by TDP. Click on the picture to see the specific value.

　　Summarizing the stability performance of the tested graphics cards, the performance of sapphire RX 590 Ultra Platinum Aurora Special Edition is quite good, which reflects the basic skills of sapphire graphics card manufacturing.

Full load temperature test:

　　In fact, the 3DMARK stress test just now also showed this temperature performance.

　　Although the heat dissipation material of the graphics card is very willing, RX 590 is indeed a big fever. Finally, the full-load temperature of the graphics card still reaches 75 C, but this temperature is OK, and the difference of several degrees Celsius will not obviously affect the user experience.

Noise test:

　　The noise of the graphics card is 54 decibels, which belongs to a quiet level, and the noise control of the graphics card is quite good.

About noise:

　　0-20 decibels: very quiet, almost imperceptible; 20-40 decibels: quiet, like whispering; 40-60 decibels: general indoor conversation; 60-70 decibels: noisy: harmful to nerves; 70-90 dB: It is noisy and nerve cells are destroyed. 90-100 decibels: increased noise and hearing loss; 100-120 decibels: unbearable, temporarily deaf after staying for one minute. Above 120 decibels: extremely deaf or totally deaf; About 300 dB or above: 20km of people in Fiona Fang are irreparably deaf.

　　From the above power consumption test, we know that the new technology is really helpful to reduce the power consumption of the graphics card (at the same frequency), so can the new technology greatly improve the overclocked ceiling of the graphics card? Let’s do the overclocking test of the graphics card.

　　We downloaded TRIXX from official website of Sapphire as overclocking software for graphics card, and overclocked the core with a gradient of 50MHz until the graphics card appears abnormal situations such as split screen, blue screen and stuck, and then gradually lowered the frequency at 10MHz. After the core frequency is determined, the memory frequency is properly exceeded in the same way.

　　The process of overclocking omits 10 thousand words, and finally we put the graphics cardThe core frequency has stabilized at 1650MHz.The overclocking amplitude is 6.8%.The actual frequency of video memory has exceeded 2120MHz.The overclocking range is 6%. The overclocking range of this graphics card really surprised me. Let’s take a look at the performance of the graphics card after overclocking.

　　The higher the frequency of the graphics card of the same specification, the smaller the income after overclocking, but the performance of the graphics card is still improved by about 5% after overclocking, and it is still a little far from touching the GTX 1070 ass. The closest one is 3DMark FSU, which is about 8% different from the GTX 1070 public version.

　　The cost of overclocking is also quite high. The power consumption of the graphics card has increased by about 60w. Strangely, the power consumption of the platform game is basically the same as that of the baking machine, but it is the same after repeated tests, probably because the frequency of the graphics card in the game is not stable. In short, players who want to overclock should remember to prepare a high-power power supply with good quality. After all, this wattage is almost catching up with RX VEGA 56.

　　The comprehensive evaluation of RX 590 is here for the time being. I believe that after reading the whole article, everyone will have a more comprehensive understanding of AMD’s new graphics card. Next is your favorite comprehensive performance percentage chart.

　　Finally, we synthesize the game performance of the graphics card at 1080p/2K and the theoretical performance of 3DMark, and get the above chart.The comprehensive performance of RX 590 with public frequency is about 18% ahead of GTX 1060, and about 11% ahead of ASUS DUAL RX 580 O8G which is close to public performance.

　　However, the graphics card is still about 25% behind the ASUS DRAGON GTX 1070 TOP8G, and about 37% behind the sapphire RX VEGA 56 ultra-platinum limited edition. However, these are non-public graphics cards, and the reduction of the non-public edition will bring the corresponding performance increase. Xiao Bian roughly estimated that RX 590 is about 16% behind the GTX 1070 public edition and about 33% behind the RX VEGA 56 public edition. Of course, this is only a rough estimate. Please read it.

I prefer to call it RX 580X rather than RX 590.

　　Previously, the RX 580 high-frequency non-public comparison RX 480 public version has only increased by 13%. Although the RX 590 also adopts the routine of frequency raising, the improvement is more sincere. GF’s 12nm technology can improve the performance of the second generation Ruilong by about 10% compared with the first generation Ruilong, and also improve the performance of RX 590 by about 12% when the power consumption is slightly increased. This 10% improvement is really good in the CPU field, but it is not enough in the graphics card field, not to mention that NVIDIA’s 10-series graphics card has an amazing 70% improvement compared with the 9-series graphics card, even if AMD’s own graphics card is upgraded, such as RX 480 compared with R9 380X.　

　　AMD may also consider this point, and did not give the new graphics card the title of RX 680, but it is the first time that AMD~90 model’s graphics card specifications have not changed ~80 model’s graphics card has not changed. I prefer to call it RX 580X rather than RX 590. (Although RX 580X already exists, it is a RX 580 vest specially supplied by OEM channel.)

Even so, RX 590 is still very competitive in the market.

　　Having said that, the pricing of RX 590 graphics card is more sincere, and most models are still set below 2000 yuan.Considering that even the public version of RX 590 still has a performance gap of at least about 10% compared with the top non-public version of GTX 1060 6GB.That ticket of GTX 1060 priced at 1900 yuan or above has no purchase value, unless your power supply quality is really poor or wattage is low.

　　Most models of RX 590 in the market, such as the sapphire RX 590 Ultra Platinum Aurora Special Edition and Dylan RX 590 Demon, are top-level non-public workmanship. In contrast, many GTX 1060 materials of 1800~2000 yuan are very poor, which makes RX 590 more competitive in the mid-range graphics card market.

　　So is the RX 580 no longer worth buying? Actually, it’s not. Now the price of RX 580 has dropped rapidly. Many beggar versions of RX 580 have dropped to 1599 yuan in JD.COM. Just like GTX 1060, it depends on whether it’s worth buying or not and the actual price.

　　In the face of the GTX 1070 graphics card, which is currently priced at about 3,000 yuan, Xiaobian can only say that the RX 590 is still fragrant.

　　It is reported that AMD’s new graphics card will be put on shelves in JD.COM at 10: 00 on November 16th.And the purchase of RX 580, RX 590 and RX VEGA graphics cards on the same day will send Blizzard game cards worth 210 yuan.Interested netizens can pay attention to a wave.

Write it at the end

　　Although the RX 590 has not improved much this time, AMD’s strategy of running in small steps is quite successful. After all, although high-end graphics cards are the facade, most people buy dessert graphics cards of around 2,000 yuan. Since high-end graphics cards can’t beat them, it is also a smart choice to continue to exert strength in mid-range graphics cards.

　　Many netizens may think that 2060 is coming soon, and it seems useless to produce this graphics card. However, according to the high cost and pricing strategy of this new generation of NVIDIA graphics cards, Xiaobian guessed that the pricing of the new generation of 2060 graphics cards should be around 2500~3500 yuan, which is no longer a competitive product in the pricing range with RX 590. The competitor of RX 590 should be the current GTX 1060 6GB. As for GTX 1070, both performance and price are not in the same range as RX 590.

　　In a word, RX 590 is a graphics card for the market, with few technical highlights. If you have any expectations for the development of A-card, you should wait for the release of 7nm game graphics card NAVI next year, when the process of A-card will be rarely ahead of that of N-card, and AMD may also greatly narrow the gap with NVIDIA by virtue of the double progress of architecture and technology.

Dylan DEVIL RX 590

　　When RX 580 was released last year, Dylan launched the top-end model DEVIL RX 580, and this time is no exception. DEVIL series is commonly known as the devil, which has always represented the top workmanship level of A card and even all graphics cards. The color scheme of red and black and the magic circle have always been the symbol of the devil series.

　　Dylan’s first DEVIL RX 590 looks basically the same as DEVIL RX 580, continuing the relatively dark design style of the devil, and its face value is online. In addition, the frequency of the graphics card will reach 1575MHz, which is the relatively high frequency RX 590.

Asus STRIX RX590 8G GAMING

　　As a card manufacturer, ASUS is naturally indispensable. This STRIX RX590 8G GAMING is the RX 590 model launched by ASUS.

　　I believe everyone is familiar with the appearance of ASUS STRIX graphics card using ancestral radiator. The model released this time is not O8G or T8G, and its performance should be relatively conservative.

　　Covering 11 provinces and cities along the Yangtze River and spanning three major plates, the Yangtze River Economic Belt not only has outstanding ecological status, but also has great development potential.

　　In the past five years, under the strong leadership of the CPC Central Committee, the provinces and cities along the Yangtze River have made historic achievements in "jointly protecting and not developing" and promoting the overall green transformation of economic and social development. The economic development of the Yangtze River Economic Belt is generally stable and the structure is optimized.

　　Break the dilemma

　　Chemical industry is no longer "encircling the river"

　　The total length of the Yangtze River in Changzhou, Jiangsu Province is only 25.8 kilometers, but there are 84 chemical production enterprises, which are very dense.

　　In the Binjiang Chemical Industry Park in Xinbei District, Changzhou City, Gao Xiaoping, a villager from Xinhua Village, said that enterprises have invested and made local residents rich; "Chemical encircling the river" has made residents suffer from environmental pollution.

　　"Crack ‘ Chemical wai Jiang ’ We are duty-bound. " Xu Yawei, secretary of the Party Working Committee of Changzhou Binjiang Economic Development Zone, said that the number of chemical enterprises in the development zone has decreased from 84 in 2019 to 41 by the end of 2020. "Shut down and turn around, the first thing to change is the development concept."

　　Such measures in Changzhou are not uncommon in provinces and cities along the Yangtze River. In the past, petrochemical, steel, smelting and other industries gathered on both sides of the Yangtze River, with a large pollutant emission base, and wastewater, chemical oxygen demand and ammonia nitrogen emissions accounted for 43%, 37% and 43% of the country respectively. To give priority to ecology and green development, we must solve the dilemma of "chemical industry encircling the river".

　　Upstream, the original chemical factory building in Linxiang Industrial Park, Linxiang City, Hunan Province is being transformed into a logistics base. Since 2018, Linxiang Industrial Park has stopped all newly started chemical projects within 1 km of the Yangtze River coastline. By the end of December 2020, nine chemical enterprises had taken the lead in withdrawing according to the plan. In Jiujiang City, Jiangxi Province, 37 small chemical enterprises within 1 km along the Yangtze River, Poyang Lake and Xiuhe River have all closed down at the end of 2019. The chemical industry once contributed nearly one-third of the industrial output value of Yichang City, Hubei Province. In 2017, Yichang formulated a three-year action plan for 134 chemical enterprises along the Yangtze River, and proposed measures such as shutting down a batch, transforming a batch on the spot, relocating a batch to the park, and changing production to a batch. This work is now nearing completion. Hubei Province proposes to complete the customs clearance and relocation of chemical enterprises within 1 km along the Yangtze River by December 31, 2020, and promote the customs clearance and relocation of chemical enterprises within 1-15 km along the Yangtze River by the end of 2022, so as to solve the outstanding problem of "chemical encircling the river" within three years.

　　The banks of the Yangtze River, where machines roared and pipelines formed a network, are now gradually returning to peace. At the same time, new industries are rising and new kinetic energy is surging, and the provinces and cities along the Yangtze River are competing to embark on the road of green development.

　　Seek high-quality development

　　On November 23, 2020, after 10 hours of intense debugging, the 0.18 mm ultra-thin electronic glass production line of Yichang CSG Optoelectronic Glass Co., Ltd. successfully reached the standard for mass production. Guangzhou Automobile Passenger Car Yichang Branch has become a benchmark factory for energy-saving and environment-friendly intelligent manufacturing, which can produce a car every 52 seconds … …

　　After the chemical industry was changed and moved, these alternative industries quickly made up the position. At present, the output value of new materials, biomedicine, electronic information and advanced equipment manufacturing accounts for 41.9% of Yichang’s total industrial output value. According to the Ministry of Ecology and Environment, from January to September 2020, the proportion of days with excellent air quality in Yichang was 88.3%, up 21.3% from the same period in 2019.

　　Tongling City, Anhui Province, named after copper, is prosperous because of copper. With the development of the industry entering the bottleneck period, how to promote industrial upgrading and achieve high-quality development has become a new topic in Tongling.

　　"The industry needs to be transformed and copper foil needs to be developed, but we have no technology. What should we do?" For a while, Jia Jintao, the head of Tongguan Copper Foil Company, was puzzled by product innovation. Yuansheng Jin, head of high-tech department of Tongling Science and Technology Bureau, found that many copper enterprises are facing the same problem of scientific and technological innovation. "From the production of electrolytic copper to the research and development of copper foil and copper plate, improving the added value of products is the key."

　　Tongling Science and Technology Bureau included Tongguan Copper Foil Company in the application guide of key scientific and technological projects, and borrowed money from universities and research institutes. Jia Jintao said, "With the help of experts and professors, the company’s electronic copper foil stress research project has been carried out smoothly, and I am full of confidence in the next development!"

　　At present, Tongling is actively introducing deep processing projects of copper-based new materials, gradually getting rid of the primary processing stage of raw materials, and forming many industrial chains such as "plate, belt, tube, rod, wire, foil and powder". Recently, Tongling has issued a plan to promote the deep integration of copper-based new materials industry with new energy vehicles, electronic information and high-end equipment industries, and increase the added value of products.

　　Changzhou Binjiang Chemical Industry Park shut down the chemical plants within 1 km along the Yangtze River and withdrew the coastline of the Yangtze River, which gave two enterprises of Wuxi Xingda Group a "new life" in the park. Xingda Group is determined to shut down two old factories and invest 3 billion yuan to rebuild new projects in different places in the park. According to the relevant person in charge, the new plant has opened up the upstream and downstream industrial chains, which not only reduces the cost and safety risks, but also reduces the discharge of wastewater and waste gas through new processes. According to estimates, after the completion of the new project, the annual sales of the enterprise will reach 6.5 billion yuan, the annual tax payment will be about 230 million yuan, the average tax revenue per mu will exceed 1 million yuan, and the wastewater emission reduction will exceed 20%.

　　Jiujiang city put an end to "polluted" GDP and fiscal revenue. In recent years, Jiujiang has rejected more than 400 investment projects that have a negative impact on the ecological environment, leaving the development space along the Yangtze River to emerging industries led by port economy and digital economy. On the south bank of the Yangtze River and the west bank of Poyang Lake, a Poyang Lake Ecological Science and Technology City with a planned area of 158.53 square kilometers is emerging, and leading enterprises have settled in. "It turned out that attracting investment from all over the world was only an economic account. Now it is a political account, an ecological account, a social account and a long-term account." Wu Bin, director of the Office of the Leading Group for Open Development along the Yangtze River in Jiujiang, said.

　　Promote synergy

　　Dancing upstream and downstream

　　Every day, Chongqing Minsheng Shipping Company has cargo ships departing from Chongqing Orchard Port, descending along the river, transshipping at Jiangsu Taicang Port and then heading for Shanghai Yangshan Port.

　　At the beginning of 2020, Chongqing Orchard Port, Taicang Port and Shanghai Port opened the "Shanghai-Chongqing Direct Express Line". "On average, it runs every day. Compared with ordinary liners, the overall logistics timeliness has increased by more than 30%." Niu Xiandan, general manager of Chongqing Orchard Port International Logistics Hub Construction and Development Co., Ltd. said that in the future, the mechanism will be innovated to reduce the waiting time for ships to wait for the gate and change ships, and the voyage will be compressed for another two to three days.

　　In Taicang Port and Yangshan Port downstream, the new customs clearance mode has also reduced the transportation time by at least two days. On November 4, 2020, 23.47 tons of red oak board arrived in Taicang Port from Yangshan Port, which is the first time that Yangshan — The first order after the formal operation of Taicang Port’s "linkage loading and unloading" supervision mode marks the comprehensive landing of customs clearance integration between Shanghai and Taiwan.

　　"Taicang Port is an extension of Yangshan Port. After the imported goods are released in Yangshan Port, they can be directly transported to Taicang Port by special barges. The export goods arrive at the wharf of Taicang Port. After the customs declaration is released, they can leave the country directly from Yangshan Port. " Vivi, Deputy Chief of Logistics Management Section of Taicang Customs, said that this mode has solved the problems of customs declaration and second arrival, which can greatly save the logistics cost and customs clearance time of enterprises.

　　The Yangtze River, a water transport artery that runs through the east and west, is a rare golden waterway in the world, and its freight volume ranks first among inland rivers in the world. In the past five years, the provinces and cities along the Yangtze River have made great efforts to promote coordinated development and add color to this golden waterway.

　　Sichuan and Chongqing have innovated the inter-provincial consultation and cooperation mechanism, established the three-level operation mechanism of Sichuan-Chongqing cooperation to promote the construction of the twin-city economic circle in Chengdu-Chongqing area, including the joint meeting of the party and government, the coordination meeting of executive vice-provincial mayors and the joint office, and promoted 31 major projects jointly implemented by Sichuan and Chongqing, with a total investment of about 556.3 billion yuan.

　　Such a mechanism is being promoted in the upper and lower reaches of the Yangtze River. The National Development and Reform Commission, together with 11 provinces and cities along the Yangtze River, established the "1+3" inter-provincial consultation and cooperation mechanism in the Yangtze River Economic Belt, and achieved a number of achievements in joint prevention and control of ecological environment, interconnection of infrastructure, and joint construction and sharing of public services. Three provinces and one city in the lower reaches of the Yangtze River took the lead in establishing a cooperation and coordination mechanism of "three-level operation, unification and separation, pragmatism and high efficiency"; Four provinces and cities of Chongqing, Sichuan, Guizhou and Yunnan in the upper reaches of the Yangtze River signed an agreement to establish an inter-provincial consultation and cooperation mechanism in the upper reaches of the Yangtze River; Jiangxi, Hubei and Hunan provinces in the middle reaches signed an agreement to establish an inter-provincial consultation and cooperation mechanism in the middle reaches of the Yangtze River … …

　　The institutional mechanism has been broken, and the multi-level consultation and cooperation mechanism framework has taken shape. The upstream and downstream of the Yangtze River Economic Belt are working together to develop a new chapter.

　　(Reporter Wang Weijian, Jiang Yunlong, Song Haoxin, Fan Haotian, Shen Zhilin, You Yi, Ju Yunpeng, Wang Dan)

　　Time: May 10th.

　　Agenda: General Secretary of the Supreme Leader inspected and presided over a symposium on promoting the construction of xiong’an new area with high standards and high quality in xiong’an new area, Hebei Province.

　　As xiong’an new area is near, there are more construction sites and more new buildings. Through the window, General Secretary of the Supreme Leader stared at this miraculous new city.

　　This is the third time that the General Secretary has visited Xiong ‘an in six years, and the transportation has changed. It’s my first time here, or by car. That was in February 2017, General Secretary of the Supreme Leader set off from Zhongnanhai, more than 100 kilometers south, and went to a farmland in Anxin County, Hebei Province for on-the-spot inspection. Going again this time, Fuxing has been flying fast for more than 50 minutes, and Xiong’ an has been integrated into the "one-hour traffic circle of the capital".

　　Xiong ‘an’s appearance has changed. In the past, she was a regional short board under the "siphon effect" of Beijing and Tianjin. Next to Baiyangdian Lake, planted with crops, ancestors never thought that they would usher in a once-in-a-lifetime historical opportunity in the new era and become a hot spot for the coordinated development of Beijing-Tianjin-Hebei and a benchmark for high-quality development.

　　It has been brewing for a long time and has been waiting for a long time. Anxin, Xiongxian and Rongcheng are surrounded by Baiyangdian, the "Pearl of North China". The new name of this land, Xiong ‘an, was announced to the world in April the year after the first investigation by the General Secretary. Since then, "Millennium Plan, State Affairs" has been written in history.

　　On the coast of Bohai Sea, on the bank of Taihang Mountain and at the foot of Yanshan Mountain, it is consistent that "the Party Central Committee always gives the greatest hope" in investigation, decision-making, planning, construction, ground breaking and jointing. In the past six years, we have not only witnessed the emergence of the "city of the future" in the new era, but also witnessed the sound of the concept of urban planning and construction advocated by the General Secretary of the Supreme Leader.

　　 　"Bull’s nose" and "spreading pie" are strategic choices.

　　Tracing back to the birth of xiong’an new area, we should start with the capital Beijing.

　　Being too big is one of the "growing pains" in Beijing. When the "ceiling" of "spreading the pie" construction is within reach, pressure and pain points follow. As early as 2014, when investigating in Beijing, the General Secretary of the Supreme Leader compared the image of urban construction and development as "you can’t step on watermelon skin and slide wherever you go". "There should be a top-level design and control, and the limit should be set, beyond which you can’t grow any more".

　　Looking inward, it is difficult to solve the problem; Looking outside, my thoughts suddenly became clear. The general secretary put forward the coordinated development strategy of Beijing-Tianjin-Hebei to relieve the function of Beijing’s non-capital, which was full of vitality.

　　Whether it is "seeking a territory from the overall situation" or "blocking it is better than sparse", the Chinese civilization with a long history has a new vitality in the new era. The general secretary described "relieving the function of Beijing’s non-capital" as "moving a surgical operation" and "breaking the mindset of circling on one acre and three points".

　　Another problem has followed, and it is relieved outward. Where is the bearing place? Not too far, not too close, many factors are weighed and compared, so xiong’an new area came into being.

　　The bearing place is the reason for the birth of the new district and the initial heart of the Millennium plan and national affairs. "To link up with Beijing’s non-capital function transfer, we must keep this initial intention in mind." The general secretary told me.

　　The country is big and the party is big. On the land of more than 9.6 million square kilometers, the decision-making and deployment of the CPC Central Committee is like an armband. In Beijing, Tianjin and Hebei, with a population of more than 100 million and a land area of 216,000 square kilometers, it is a common responsibility and a common future to nurture a new area with unlimited possibilities.

　　Spread the map, Beijing-Tianjin-Hebei "different petals, but concentric petals." A picture, a chess game, a strong momentum, the power is cooperating, and the future is also cooperating.

　　From a collaborative perspective, go to see the general secretary’s investigation in Xiong’ an. At the construction site of Xiong ‘an Intercity Station and International Trade Center Project, he watched the sand table and boarded the platform. On the construction site in full swing, the headquarters of central enterprises in Beijing and the second-and third-tier subsidiaries are being built.

　　"World vision, international standards, China characteristics, high-point positioning" is a modern new city, but also a new road to the future, branded with the essential features of Chinese modernization.

　　When the general secretary talked about Xiong’ an at the Standing Committee of the Political Bureau of the Communist Party of China Central Committee meeting in February 2018, he described the imprint of a city:

　　"The establishment of the Shenzhen Special Economic Zone in the early days of reform and opening up has created the speed of Shenzhen. Today, 40 years later, we set up xiong’an new area to aim at 2035 and the middle of this century ‘ Two steps ’ The goal of creating ‘ Xiong ‘an Quality ’ It has become a national model in promoting high-quality development. "

　　 　"Fast" and "Slow" are the visions in a blueprint.

　　A thousand-year plan is an extraordinary pen.

　　The second time I went to Xiong’ an was in January 2019. General Secretary of Supreme Leader made an in-depth investigation of xiong’an new area Planning Exhibition Center.

　　This fertile ground for sowing hope, after the thunder two years ago, has been brewing the power that affects the future: planning.

　　Lay the chessboard first, then move it. "I have said many times that planning is the first thing to look at when investigating a city. Planning science is the biggest benefit, planning mistakes are the biggest waste, and planning toss is the biggest taboo."

　　At the beginning of the establishment of the new district, facing the urgent expectation of the outside world for a new city from the flat, where to go? Behind the choice is foresight and determination. General Secretary of the Supreme Leader solemnly warned: "xiong’an new area will be our historical legacy for future generations" and "Plan every inch of land clearly before starting construction, and don’t leave historical regrets".

　　In two years, the plan has been polished repeatedly, and how many times it has been placed on the desk of Zhongnanhai. One foot, one inch, one stroke, one painting, the male who sinks down slowly and steadily.

　　"In the past two years, almost no bricks and tiles have been moved. Now that there is a blueprint, Xiong’ an has shifted from the top-level design stage to the substantive construction stage, and this year may be a hot situation. " The General Secretary’s second trip to Xiong ‘an clearly marked the development rhythm of Xiong ‘an.

　　Fast or slow? In a strategic vision more than 30 years ago, we can see the general secretary’s consistent concept of urban work. Today, we are standing at the source of creating the future. At that time, the supreme leader comrade wrote in the preface of "Fuzhou’s 20-year economic and social development strategy".

　　Time has recorded the rapid development under slow planning. In 2021, when he visited Fuzhou, the general secretary said with emotion: "The current construction is in line with this direction, consistent with our vision at that time, and it has developed better than our vision."

　　"I have never seen such a plan for a city." "I have never seen the above ground, underground, ‘ Cloud ’ On ‘ Tri-cities ’ Integrated planning and construction "… … Slow and steady, and seize the day. Xiong’an new area has taken a development path that no one has taken in human history, and expanded the development space of Chinese modernization.

　　Chinese modernization is a modernization with a huge population. When hundreds of millions of people flood into cities and towns, the concept of intensive land use is bound to run through the planning and design. This survey looked at the construction of Xiong ‘an Intercity Station, and the General Secretary of the Supreme Leader mentioned the traffic problem, which is one of the "big city diseases": "We should work hard to build a three-dimensional comprehensive transportation network, make full use of underground space, and strive to build a city without ‘ Urban disease ’ The city of the future. "

　　From the report of the 19th National Congress of the Communist Party of China, which emphasized "planning from a high starting point and building xiong’an new area with high standards" to "building xiong’an new area with high standards and high quality", Report to the 20th CPC National Congress, who joined the Party, went through the time sequence and drew a blueprint to the end.

　　During this trip, General Secretary of the Supreme Leader continued to emphasize that the high-standard urban planning blueprint should be truly turned into a high-quality realistic picture of urban development.

　　 　"Water" and "City" are harmonious symbiosis in a picture.

　　The general secretary is concerned about Baiyangdian.

　　The first time he went to Xiong ‘an, he went to see Baiyangdian. At the bottom of the nine rivers, water and rhyme are in harmony. The Supreme Leader General Secretary said: "When I was a child, I read the story of Zhang Ga, a soldier, and I was very fascinated here." The second time, the general secretary asked about the recent situation of Baiyangdian in the planning and exhibition center, and he was very concerned.

　　This time, before presiding over the symposium on promoting xiong’an new area’s construction with high standards and high quality, the General Secretary took the time to watch a short video of Baiyangdian. The progress of dredging and connecting hundreds of lakes is in my heart.

　　Water and city, a necessary question for urban development.

　　"At that time, the site was chosen here to protect Baiyangdian, not to damage Baiyangdian. The city and the lake should reflect each other and complement each other. " Setting the city by water, the land by water, the people by water, and the production by water are important dimensions for the development of the Supreme Leader General Secretary.

　　Opening the map of China, the lack of abundant resources in the north and abundant resources in the south is one of the characteristics of water resources distribution in China.

　　The problem of water shortage was felt when I was young. In February 2014, when listening to the report on the coordinated development of Beijing-Tianjin-Hebei, the Supreme Leader General Secretary solemnly warned: "The water shortage problem in North China is already very serious. If we don’t pay attention to protecting the ecological spaces such as forests, lakes and wetlands that conserve water, and continue to overexploit groundwater, the intensity of natural retaliation will be even greater."

　　Water resources, the hard constraint of development.

　　At the beginning of the planning and construction of Xiong ‘an, the General Secretary of the Supreme Leader repeatedly stressed the need to save water and conserve water sources: "The abundant water resources here are good for building the city, but in retrospect, you should not destroy our water source and our ecological wetland. Pay attention to this aspect because of the city. "

　　The relationship between "water" and "city" is a mirror of the relationship between man and nature.

　　Mountains and rivers, forests, fields, lakes, grass and sand, the elements of natural ecology, determine the resource endowment and location conditions of a place, and determine the regional development space and resource and environmental carrying capacity. "How much soup there is?" General Secretary of the Supreme Leader used this simple sentence to explain that planning and development should be based on reality and adapt to local conditions.

　　Xiulin, Green Valley and Dianwan form the ecological space skeleton of xiong’an new area’s starting area. Looking at the "forest", when I went to Xiong ‘an for the second time, the Supreme Leader General Secretary drove through the "Millennium Xiulin" to see the growth of trees. Nowadays, young trees are flourishing. Planting trees before building cities has become a new concept in the construction of new districts.

　　Look at the "city", look up and travel, and the proportion of green transportation in the starting area of the new district accounts for 90%; Building a building, clear green building standards, how much construction waste to reduce and how much energy to save have all become the key to decision-making.

　　At this symposium, General Secretary of the Supreme Leader once again stressed that xiong’an new area should adhere to green and low-carbon development and build itself into a model city with green development.

　　 "New" and "Old" are the pulse inheritance of one article.

　　Mountains and rivers surround the city, and culture builds the city. The "City of the Future" and the Millennium context complement each other. "Culture is the soul of a city."

　　Protection and development, transformation and new construction, tradition and modernity are faced by Xiong ‘an in the construction, and thousands of cities are also experiencing it. Behind the priorities, it is also answering the question of "what road to take" in the largest urbanization process in human history.

　　Old trees don’t move, ancient buildings don’t tear down, and ancient archways don’t move … … In 2018, xiong’an new area launched the special action plan of "Remembering Homesickness".

　　"The city is a science. It has meridians, pulse and texture like the human body. If you don’t treat it scientifically, it will get sick." General Secretary of the Supreme Leader once quoted this sentence by architect Liang Sicheng. History and culture are also the meridian texture of the city.

　　Open the Planning Outline of xiong’an new area, Hebei Province, and "historical and cultural protection" is a separate section. General Secretary of the Supreme Leader clearly pointed out that the construction of xiong’an new area should "persist in protecting and carrying forward the excellent Chinese traditional culture and continue the historical context".

　　"Only by persisting in moving from history to the future and forging ahead from the continuation of national culture, can we do a good job in today’s cause." The wave of urbanization is surging forward, and the balance between "new" and "old" is crucial to the future.

　　The "old" that I care for is the history and civilization that has been passed down for thousands of years;

　　The "new" of positive development is a new format, new model, new growth point and new kinetic energy under the tide of the times.

　　At the symposium on this trip, the General Secretary of the Supreme Leader mentioned the word "new" many times: "We must fully implement the innovation-driven development strategy, promote the frontier policies and measures of reform and opening up in various fields and forward-looking innovation pilot demonstration projects in Xiong’ an, and strive to build new functions, form a new image, develop new industries, gather new talents, and build new mechanisms to make xiong’an new area an innovative highland and a hot spot for entrepreneurship in the new era."

　　In Xiong ‘an people’s eyes, the past urban development model was industrialization driving urbanization, while Xiong ‘an was urbanization driving industrialization and informatization.

　　During this inspection, General Secretary of the Supreme Leader arrived in Xiong ‘an, got off the high-speed train and first looked at Xiong ‘an Station and its Zangang area. The "urban blank space" in front of us has unlimited potential. The general secretary said: "The Zangang area should be built into a high-end high-tech industrial cluster, so that visitors from all walks of life can feel the new modern atmosphere of xiong’an new area as soon as they arrive in Xiong ‘an".

　　The new atmosphere of modernization, where is "new"?

　　China has entered a new stage of development. The new development concept is integrated into the blood and bones of Xiong’ an construction.

　　"First of all, the new district should be forward-looking and leading in the concept of planning and construction." Smart, green and innovative, these bright business cards tell the new story after the new development concept "settled in Xiong’ an".

　　History and future meet here.

　　"Jiangshan has been a good guest since ancient times. Who is the Taihang for misty rain?" This eternal question on the tower of Guxiong Prefecture has passed through long years.

　　 "Seeing things" and "seeing people" are the initial intentions of people’s cities.

　　"City, so Shengmin also." A city has not only reinforced concrete, but also wind and rain, flowers and birds singing, and homes to live in.

　　This time in Xiong ‘an, General Secretary of the Supreme Leader went to Rongdong District, the first centralized built-up area in the new district: "I have been worried about the relocated people, and I am very pleased to see that everyone has a good life. To build a good xiong’an new area, it is important to link up living and working in peace and contentment, so that the people can live steadily, live safely and have a head start. "

　　The city of the future is the city of the people.

　　Xiong’ an has builders, relocated people, entrepreneurs, and "aborigines" who have turned farmers into citizens. As the sun rises and sets, they grow up with Xiong ‘an. The general secretary clearly pointed out: "We are not building a beautiful new city, but just building a new city for the people to live a better life."

　　"Serving the people wholeheartedly and providing fine urban management and good public services for the people are the focus of urban work, and we can’t see things but people." In December 2015, at the Central City Work Conference, the General Secretary of the Supreme Leader deeply thought about the initial heart of the city.

　　"The concept of making people’s lives more comfortable is integrated into the blood of urban planning and construction and reflected in every detail."

　　Governing the city, under the "embroidery" effort.

　　"It is necessary to promptly perceive the worries, worries and worries of community residents and solve them one by one". "Vegetable basket", "rice bag" and "fruit plate", when working in the local area, the General Secretary of the Supreme Leader put these "small things" of people’s livelihood on his desk as major events.

　　The essence of modernization is human modernization.

　　For the people, rely on the people and benefit the people. The "Xiong ‘an Scene" of Chinese modernization takes the people as the center and explores a new path to build a modern city with new development concepts. Foreign media commented that Xiong ‘an is a tangible and vivid model of Chinese modernization.

　　For thousands of years, China, a rural area, is experiencing the most magnificent changes of human society in the 21st century in the eyes of western scholars, as well as the largest and fastest urbanization process in the world history since the reform and opening up.

　　New cities, new explorations and new roads are full of thank you sir, with historical patience and infinite vitality.

　　In just 6 years, I went to Xiong’ an three times. Millennium plans and national events are often in the deep concern of the Supreme Leader’s General Secretary.

　　In just six years, xiong’an new area has gone from scratch, from blueprint to real scene, a future city without "urban diseases", a "people’s city" suitable for business and living in a new era, and a high-level and modern city is springing up.

　　This is another miracle written on the land of China in the new era.

　　 　For some time, the drought in many places in China has developed rapidly, superimposed with high temperature and heat damage, which has adversely affected the production and life of many people. A few days ago, the Ministry of Agriculture and Rural Affairs, the Ministry of Water Resources, the Emergency Management Department and the China Meteorological Bureau jointly issued an urgent notice, demanding that the relevant areas do their best to prevent and reduce disasters, go all out to win the battle against high temperature, heat, drought and harvest of autumn grain, and clearly put forward that we should do everything possible to broaden drought-resistant water sources, strengthen the scientific dispatching management of water sources such as rivers, lakes and reservoirs, and strive to ensure the demand for agricultural irrigation water.

　　 　"Thirst" cannot be delayed, and ensuring people’s water use is the top priority. Allowing rural residents to drink "safe water" and "safe water" for a long time is the basic premise of getting rid of poverty, an important content of realizing rural revitalization, and the proper meaning of protecting farmers’ rights and interests. In addition, as the saying goes: "Spring drought is not a drought, and autumn drought is halved." To prevent the autumn grain from decreasing production, we must do our best to fight drought and win the battle of autumn grain harvest.

　　 　Earlier, the person in charge of the relevant departments of the Ministry of Water Resources said that the drinking water safety situation of rural people in drought-stricken areas had been comprehensively explored, so as not to miss one household or one person. It is an urgent and important task to solve the drinking water difficulties of urban and rural residents and let the people drink "safe water" and "safe water".

　　 　According to the news from all sides, many places have also acted quickly. From water storage and water conservation, to water replenishment, to water supply by turns and emergency water supply in sections and districts, in order to ensure the people’s water use. In addition, from opening up new water sources, to time-sharing water supply, and then to pulling water to deliver water, relevant local departments have also introduced targeted measures according to local conditions to minimize the impact of drought.

　　 　Some implement artificial precipitation enhancement to "quench thirst" for the land; Some are "well organized" to fight drought, and "big wells, small wells, deep wells and old wells are together"; Others mobilize scientific and technical personnel to show their strength at critical moments. For example, agricultural technicians help growers to use water sources such as wells, rivers, ponds and canals to replenish water for irrigation, timely topdressing panicle fertilizer, and strengthen pest control and monitoring. Drought resistance and bumper harvest, proper measures and comprehensive efforts can achieve great results.

　　 　It should also be noted that it is difficult to achieve the expected results by individual strength alone in dealing with this drought. Farmers everywhere took action spontaneously, and their spirit was commendable. However, it is necessary to unite the group to fight drought, especially the relevant departments should organize capable personnel, mobilize the forces of all parties, and form a huge and sustained joint force to maximize the effectiveness of drought relief. In this process, we must also fight drought scientifically, spend money on the cutting edge and use our strength in critical areas.

　　 　Drought resistance is not a matter of one department, but needs multi-department linkage. The emergency notice issued by the 4 departments this time reflects this point. The water conservancy department should strengthen the scientific dispatching management of rivers, lakes, reservoirs and other water sources, the emergency department should preset emergency response forces and materials and equipment for flood control and drought relief, the meteorological department should dispatch operational aircraft to the severely drought-stricken areas in time, and the agricultural and rural departments should further improve the technical guidance for fighting disasters and harvesting crops. While completing their own work, they should also hold hands with each other and strengthen linkage to better cope with this round of drought.

　　 　China is a country with frequent floods and droughts, and has accumulated rich experience in the long-term drought relief process. However, in the face of this rare serious drought, we must not be the slightest bit careless. It should be admitted that it is not easy to do a good job in drought early warning and strengthen risk management, but it does not mean that human beings can only do nothing. We should vigorously fill shortcomings, plug loopholes, and improve drought resistance, optimize drought resistance means with the greatest strength, and introduce advanced technology to effectively reduce the harm caused by drought.

　　 　Strengthening the prevention and control of natural disasters is related to the national economy and people’s livelihood, and to everyone’s life safety. Drought is the command. We should not only make strategic preparations for "fighting against severe drought and long drought", but also try our best to refresh more effective "fighting methods" in tactics, improve the drought-fighting effect and fully protect the national economy and people’s livelihood.

In 2014, China’s first doctor group outside the system was established. Subsequently, various forms of doctor groups such as outside the system, inside the system and online have emerged. According to incomplete statistics, there are 160 famous doctor groups on the list, which shows the vitality of the development of doctor groups. Doctor group is a new thing in the process of promoting the construction of healthy China and deepening the reform of medical and health system in China. From today, we will launch a special report on "Visiting Doctor Group", focusing on the development status of doctor group, hoping to attract everyone’s attention.

The doctor group provides one-stop and continuous service, which is completely different from the doctor’s "going to the hole" and "flying knife"

Ms. Shen, 61, discovered atrial fibrillation in 1999. She has undergone three operations and her condition has not been alleviated. She learned that Hartrim Cardiologist Group can do one-stop hybridization surgery, so she found Liu Xingpeng, an expert of the group. Liu Xingpeng organized a team of experts in the group to carefully analyze Ms. Shen’s condition, worked out a feasible surgical plan, and performed surgery in October 2016. Since then, Ms. Shen has bid farewell to atrial fibrillation that has plagued her for 17 years.

Ms. Shen had the operation in Hebei Yanda Hospital. Liu Xingpeng is a cardiologist at Beijing Chaoyang Hospital and one of the co-founders of Hartrim Cardiologists Group. Yanda Hospital is the second practice place of Liu Xingpeng and one of the cooperative hospitals of the Group.

"It truly reflects the patient-centered and gathered many experts in cardiac surgery. As a patient, I simply can’t invite so many well-known experts. " What Ms. Shen is talking about is the characteristic of Hartrim Cardiologist Group-multidisciplinary expert group collaborative diagnosis and treatment mode, that is, a group of relatively fixed experts from more than two disciplines discuss a patient’s organ or system diseases in a normal way, form a diagnosis and treatment plan, and execute it by members of the corresponding disciplines.

"Unlike the consultation with administrative departments in public hospitals, this is a multidisciplinary expert group collaboration initiated on the initiative according to the needs of patients, which is completely considered for patients and does not involve the interests of departments." Fan Rui, CEO of Hartrim Cardiologist Group, said. The hybrid surgery mentioned by Ms. Shen is a new type of surgery developed by the group, which can enable multiple specialist teams to cooperate and provide patients with various necessary surgical treatments during one operation, thus reducing the pain of patients undergoing multiple operations.

Doctors of the doctors’ group practice in Yanda Hospital, which is not the so-called "flying knife". In 2015, the doctor group cooperated with Hebei Yanda Hospital at the beginning of its establishment, and in 2016, the "1+N" cooperation mode was launched, that is, doctors from large 3A hospitals in the group went to the cooperative hospital full-time to be responsible for the daily diagnosis and treatment of the cardiac department, and many experts in the group fully supported it. Tan Chen, the chief physician from the Army General Hospital, has been stationed in Yanda Hospital full-time since March 2016, and led a cardiac ward. With the support of many experts such as Mei Ju, a professor of cardiothoracic surgery at Shanghai Xinhua Hospital, more than 400 cardiac operations were completed in the first year of its opening. There is another model "N+1", that is, there are many experts in the system to help the same hospital collectively. "1" refers to the leader of the cardiac discipline of the cooperative medical institution itself.

"We not only helped cooperative institutions in terms of discipline development, but also set up a team of follow-up nurses. Follow-up nurses are mainly responsible for supervising patients to take medicine, reminding them to review regularly, follow-up and other services. The general consultation needs of patients can be met by asking the follow-up nurse, and doctors can be found through the follow-up nurse when treatment is needed. The group provides one-stop and continuous services, which is completely different from the doctor’s’ walking the hole’. " Fan Rui said.

In the form of a company, the doctor group absorbs doctors with high technical level to practice in a managed and organized way, and is strong and powerful.

In addition to Yanda Hospital, Hartrum Cardiologist Group also cooperates with five hospitals, and the experts of the group make house calls or provide technical assistance in the cooperative hospitals with the advantage of "N" to jointly build a cardiology discipline.

In May 2015, Liu Xingpeng and other seven first-line cardiologists from six top-three hospitals in Beijing jointly established Hartrum Heart Rate Specialist Group, which is the first specialist group in the field of heart disease in China. In 2017, it was renamed Hartrim Cardiologist Group. The services mainly include arrhythmia, coronary heart disease, heart failure, structural heart disease and other diseases, and there are four sub-professional expert teams and nurse teams to provide diagnosis and treatment and technical output services for cooperative hospitals. Due to the multi-disciplinary cooperation of heart disease and the characteristic hybrid surgery, the group’s diagnosis and treatment volume and business income have soared year after year.

The Donglei Brain Doctor Group, which was established in the same year as Hartrem, was initiated by Song Donglei, an expert in neurosurgery at Huashan Hospital affiliated to Fudan University, and is also a specialist doctor group. The group has very high requirements for doctors’ professional skills and academic level. Most of the group experts and cooperative experts have overseas study and study backgrounds, focusing on the diagnosis and treatment of brain neurological diseases. The founders and experts of Donglei Brain Doctor Group are mostly full-time doctors who leave the system. When cooperating with the hospital, the full-time doctors of the group need to sign a labor contract with the hospital and register the cooperative hospital as the practice place; If it is an identity within the system, it is enough to carry out multi-point practice filing.

The reporter found that these doctor groups are all in the form of companies, attracting doctors with higher technical level to practice in a managed and organized manner. They combine with each other with their technological advantages to obtain technical value returns in the market.

In June 2016, the practice license of medical institutions in the outpatient department of Shenzhen Bode Jialian Doctor Group was officially approved. Nearly 300 contracted experts of the doctor group can carry out disease diagnosis and treatment in the outpatient department, and the clinical disciplines cover 26 specialties, including gastrointestinal surgery, hepatobiliary surgery, congenital heart disease, asthma and chronic obstructive pulmonary disease.

Chuanpai Doctor Group is a specialist group specializing in the field of pain medicine. At present, it has purchased a second-class hospital of integrated traditional Chinese and western medicine and named it "Chuanpai Medical Prescription Museum".

There is also a kind of doctor group, which belongs to the management service type and is similar to the doctor broker, such as Everyone Medical Association and Zhongyu Doctor Group. This kind of doctor group is positioned as a doctor’s agent company, which is mainly responsible for providing management services related to doctors’ practice, such as establishing an information exchange platform, helping doctors choose contracted hospitals, centralized negotiation, and risk response.

In the management service doctor group, there are also some Internet doctor groups such as Xingxiangyuan. This kind of doctor group mainly relies on the Internet platform to become a professional assistant and multi-point practice platform for doctors, and relies on the Internet to achieve accurate matching between doctors and patients offline. On the one hand, it provides consulting, brand communication, customer development, service operation, payment system, legal risk control and other services for the doctor team; on the other hand, it serves as an information release and integration platform for doctors and patients and acts as an intermediary.

Doctors are not affiliated resources of public hospitals, but common resources of the whole society.

Most of the founders of doctors’ groups are already big-name doctors. Why should we start a doctor’s group? Huo Yong, the co-founder of Peking University First Hospital and director of the Department of Cardiology, said that the doctor group is an organizational form that adapts to the transformation of the social system, and it is more compact and efficient, which is convenient for doctors to better safeguard public health. "The situation that doctors only belong to hospitals will definitely change, and doctors should be freelancers." He said that it is a common phenomenon for doctors to go out from hospitals and form a doctor group to partner, sign contracts and engage in practice, but it has just started in China.

Huo Yong has been a cardiovascular doctor for 35 years. In the course of practicing medicine, he found that the interventional therapy technology of coronary heart disease in China is becoming more and more mature, but the mortality rate of coronary heart disease is also rising. Therefore, interventional therapy alone is not enough, and we must consider it as a whole and pay more attention to primary, secondary, tertiary or even zero prevention. "Through the organization of doctors’ groups, more hospitals, especially primary hospitals, will be promoted to join, and industry standards and standardized procedures for cardiovascular treatment will be established." He believes that the demand for cardiovascular treatment in county hospitals is the most urgent. Because the regional population is relatively stable, the concept of tertiary cardiovascular prevention can be well practiced and people’s health level can be improved.

It is one of the main reasons for the establishment of most doctor groups to better rely on technology to obtain sunshine income. "I founded the People’s Medical Association with the aim of establishing a mutual aid platform for multi-point practice. I am also a doctor in Fuwai Hospital of China Academy of Medical Sciences. I also have to go out for outpatient service and have surgery. Under the premise of not affecting my job, I will make the platform bigger and help doctors use their own technology to treat more people, especially grassroots people, so that they can enjoy quality medical services at home. " Hongtaosun, the founder of the All-China Medical Association, said that the profit of the All-China Medical Association is very thin, but the income of doctors who go out for an operation is very considerable, which greatly improves the income level.

The All-China Medical Association is the first doctor group within the system in China. Some experts have commented that it not only created a precedent for doctors to start businesses within the system, but also opened a door across the system for deepening medical reform. Hongtaosun said that Dr. China’s personal brand has not been established, and it is still difficult to practice completely freely outside the system. The best business model is to practice more within the system.

Nowadays, there are more and more doctor groups inside and outside the system, led by doctors, capitalists and pharmaceutical companies. After many investigations, Miao Yanqing, a researcher at the Health Development Research Center of the National Health Planning Commission, roughly counted that the number of well-known doctor groups in the country has reached 160, and a few doctor groups have just been established and are not known to the industry.

Miao Yanqing believes that the increasingly relaxed policy has created a good environment for the emergence of doctor groups. From 2009 to 2017, China has successively issued a number of policies to support and encourage the rational flow of medical personnel between different medical institutions, and gradually realize the goal of "one registration and regional effectiveness". In particular, "Healthy China 2030" Planning Outline clearly puts forward "actively exploring doctors’ free practice, individual doctors signing services with medical institutions or forming doctors’ groups".

"At present, a single mode of medical service supply is difficult to meet people’s diversified needs. From the aspects of medical platform, doctor’s practice mode, people’s choice of medical treatment, medical insurance, etc., the doctor group has promoted the transformation of medical services from a centralized supply mode to meeting diversified medical service needs, and explored new formats for building diversified medical service supply. " Miao Yanqing said.

Cai Jiangnan, director of the Center for Health Management and Policy of China Europe International Business School, believes that the problem of doctors has been the bottleneck of medical reform for many years. Doctors’ groups touch on a series of institutional issues such as graded diagnosis and treatment, doctors’ employment treatment, etc., which are likely to become the breakthrough of medical reform and should be supported and cared for. "Doctors are not affiliated resources of public hospitals, but common resources of the whole society, which should be well utilized."
