Generally, dynasties in history can maintain relatively abundant martial arts from the early days to the peak of their national strength, but in the Song Dynasty, the population accounted for 35% of the world and the GDP accounted for 75% of the world. From today’s point of view, it is a standard world power, but it seems that it still can’t compete with the Liao country in the north. What caused this rare situation in history?

Full-domain map of northern song dynasty

1. The right to release soldiers by drinking a glass of wine opened up the armed policy of the Song Dynasty, which was different from that of the previous generation.

In the early years of the Northern Song Dynasty, the army could not defeat Liao, or it was impossible to defeat Liao after Zhao Kuangyin’s death. This is mainly because the Northern Song Dynasty and Liao State were fundamentally under two different systems. The difference in system determines the strength of their army.

The Liao army or the military organization of the Khitans did not fight against the Central Plains army until the establishment of the Northern Song Dynasty. Not to mention the early tribal ambush in the Tang Dynasty, there were several records of Qidan troops going south to conquer the Central Plains in the Five Dynasties. In the confrontation with the five dynasties warlords at that time, both sides won and lost. However, the Liao army never occupied an absolute advantage, or gained a great advantage in a certain aspect. There is even an embarrassing record that after the warlord troops surrounded the five dynasties, they were rushed out of the position by their opponents and defeated the whole army.

2. In the Five Dynasties, the Khitans fought against the Central Plains Army.

However, it was also in the Five Dynasties that warlords or local military groups of our time all posed a great threat to centralization. Therefore, the political development of the Five Dynasties gradually developed from the initial late Tang model to the Northern Song model. Militarily, this development path is concentrated in the deployment of local elite soldiers to serve in the imperial army in the capital. The weakness of the border guards after the Northern Song Dynasty was the final result of this evolutionary route.

3. The areas that traditionally produced high-quality soldiers were not in the actual control area of Song Dynasty.

On the other hand, as several border regions with strong fighting in the Tang Dynasty, the Northern Song Dynasty basically didn’t touch any of them. In addition to occupying part of Hedong area, Youzhou and the whole Hetao are not under their actual control. These places are exactly the places that are the easiest to produce high-quality soldiers from the Han Dynasty to the Tang Dynasty. Because the local people have lived on the border between nomadic and farming culture for a long time, they are good at fighting and martial arts, and their folk customs are extremely tough. A large number of defectors from Central Asia and grasslands will also be stationed in the local area. These conditions are beyond the reach of mainland military sources.

The status of soldiers was suppressed to a very low level in Song Dynasty, and they were like slaves.

Since the military base is not good, and the military power and status of generals are not guaranteed, the army naturally cannot have good combat effectiveness. Even if it inherited the imperial army left by Zhao Kuangyin and the remaining Shatuo cavalry at that time, it would soon take the initiative to degenerate under this repressive system.

5. Liao country is also centralized, but it is more like the Federation.

On this basis, the Central Army of Liao State was established, including a large number of cavalry units and corresponding light cavalry forces. There are also many original Qidan aristocratic troops in the local area, which exist in the form of similar private armies. However, these private armies have never become subversive forces to overthrow the legalists, which is the advantage of the Liao federal system. Ordinary local soldiers are also feudal cavalry who depend on land for their livelihood. People with a certain status will have a small number of vassals. In battle, they will form a cavalry unit with the smallest unit.

6. Local autonomy provided Liao with a strong local army.

As for the local troops composed of other ethnic groups, including Han, Xi, Bohai, Mongolian and some Shatuo people, they all have their own infantry and cavalry organizations. The former may rely on cities and villages as units, while the latter may exist as units of cavalry or feudal leaders. When they faced Song Jun, they were often willing to play for Liao. In fact, it is also protecting its own way of life from being eroded by the more northern song dynasty.

These are the reasons why the Northern Song Dynasty could not defeat the Liao army in the founding of the People’s Republic of China. This reason is also accompanied by all the periods when the two dynasties coexisted, even when the Liao regime was wiped out by the Jin Jurchen.

　　The South Korean government will issue a notice on the import and export of strategic materials on the 24th, putting Japan back on the "white list" to enjoy simplified export procedures.

　　According to Yonhap News Agency, after the summit meeting between Japan and South Korea last month, relations between the two countries improved. On April 21, local time, the Ministry of Industry, Trade and Resources of the Republic of Korea said that the ROK initiated the process of re-listing Japan in the export white list. Previously, on September 18, 2019, the South Korean government removed Japan from the export white list in response to Japan’s export control to South Korea.

　　Yonhap News Agency reported that it is expected that the return of bilateral economic and trade cooperation between Japan and South Korea will be put on the agenda in an all-round way. At present, the South Korean government first re-added Japan to the export white list, but it will take time for South Korea to return to Japan’s export white list. An official from the Ministry of Industry of the Republic of Korea said that the domestic procedures in Japan are more complicated than those in South Korea, so it takes more time to add South Korea to the white list.

　　The official said that after the ROK first takes measures within its power, it will appeal to the Japanese side to respond. At present, South Korea and Japan are conducting further consultations on export whitelist and other matters.

　　According to a previous report by Japan’s Kyodo News Agency, the two heads of state reached an agreement on the normalization of relations after holding talks on March 16 this year. The Japanese government announced on March 23 that the strengthening measures for export control of three semiconductor-related raw materials to South Korea launched in 2019 have been lifted. On the 16th, the South Korean government announced that it would suspend the lawsuit filed with the World Trade Organization (WTO) for the cancellation of the enhanced measures, and the Japanese government also said on the same day that it would lift the measures.

Directed by Wang Jun and starring Li Bin, Yu Feifei, Mao Child and Fei Long, the love movie about Tangshan earthquake was released nationwide today. Director Wang Jun, as a witness of the earthquake, truly restored a heart-wrenching love affair between life and death in Tangshan earthquake with delicate emotions. After many roadshows all over the country, it gained excellent reputation, set off tears in the audience, and made the audience feel the shocking disaster and the pure love in a special era in laughter and tears, and was praised as "the real Tangshan earthquake movie". Ma Dehua, Li Qinqin, Li Mengnan, Peng Yu, Liu Wei, Wei Qing and many other famous talents joined in, presenting the true feelings and humanity under the ruins to the audience.

Aspect 1: Remembering the past events of the earthquake, the sincere works of the witnesses of the Tangshan earthquake.

Wang Jun, the director of earthquake survivors, once witnessed the earthquake, put three real events in the earthquake on the screen, created the most grounded characters with memories, and truly presented what he saw and felt in the disaster. After 10 years of polishing and 42 years after the earthquake, the wish work will never disappoint the audience. "Wait for me in heaven" not only sincerely reproduces the true appearance of Tangshan earthquake in Tangshan people’s hearts, but also shows Tangshan people’s true protection in the disaster and their strong and brave Tangshan spirit, and revives Tangshan people’s collective memory. It is a movie about Tangshan earthquake recognized by Tangshan people.

Aspect 2: Return to the nostalgic era and experience the tear sadism in an unprecedented disaster.

"Wait for me in heaven" tells the story that the pure and beautiful love in a special era suffered a cruel earthquake and abused the heart to stage a true love guardian that lasted for a lifetime. Subverting the sad impression of traditional disaster films, the film focuses on the earthquake itself, but it does not exaggerate the pain too much, taking the audience back to the 1970s with delicate emotions and vivid details. Sea soul shirts and military cloth bags release nostalgia, allowing you to feel the innocence of a special era. With the slow progress of the camera, whether it’s watching fireflies under the moon or walking in the sea of sunflower flowers at noon, you can "personally" experience a different kind of romance. The life-and-death separation in the ruins makes the audience burst their tears, and at the same time, they feel the precious loyal love in the nostalgic era.

Aspect 3: Many powerful players are playing Li Bin on the same stage, and Yu Feifei’s acting skills are not lost to his predecessors.

Li Bin, a powerful acting school, returned to the screen. After Lu Xiaoqian’s "love across time and space", he turned into a young man Wang Xiaotu who returned to the city and staged a 40-year affectionate guardian. With years of solid acting skills, Li Bin interpreted the young people returning home who broke through the taboo of the era and were under great secular pressure. When they shed tears on the ruins, their feelings were rich and their performances made people cry. Ou Hailian, a small town teacher played by Yu Feifei, portrayed the refreshing innocence of girls in special times. In the film, Ou Hailian ignored her father’s opposition in pursuit of true love, and her rebellious and stubborn character showed her role charm and narrowed the distance with the audience. Her precise control of emotions vividly demonstrates the state of life and death in the disaster. In order to achieve better shooting results, Yu Feifei volunteered to fast on the set, which made his body close to the physiological limit many times, and his professional attitude did not lose his predecessors. This time, Li Bin and Yu Feifei joined hands to play life and death lovers, and their acting skills beyond their age were greatly recognized. With the participation of Ma Dehua, Li Qinqin, Li Mengnan, Peng Yu, Liu Wei, Wei Qing and many other actors, the film attracted much attention. Many powerful actors gathered on the screen to revive childhood memories, and many scenes were full of impressions.

Aspect 4: The word-of-mouth of multi-city roadshows was praised, and the students laughed and cried.

In addition to the innocent love story in the Tangshan earthquake, the film also has many emotional lines such as affection, brotherhood and friendship interspersed among them, which has a strong emotional impact. Wang Xiaotu’s "earth-flavored love-seeking tour" attracted the audience to laugh, and it was also very gratifying that Mao’s brother took good care of Xiaotu. In the second half of the film, cruel disasters and unsatisfactory reality are put in front of the audience, which tears people and causes people to think deeply about love and life. In roadshows around the country, the audience was deeply moved by the delicate feelings in the film, and it was hard to hide their tears when they laughed heartily, feeling that the film "A truly grounded disaster romance". At the Tangshan premiere, many survivors of the earthquake embraced the director in tears after watching the movie, thanking him for bringing this "real Tangshan earthquake movie". The film is cruel without losing its warmth, and it is moved by sadness, which makes people cherish the beauty of present life and be grateful for life.

　　The report of the 19th National Congress of the Communist Party of China pointed out that China’s economy has changed from a high-speed growth stage to a high-quality development stage, and it is in the key period of changing the development mode, optimizing the economic structure and transforming the growth momentum. Building a modern economic system is an urgent requirement for crossing the barrier and a strategic goal for China’s development. Crossing the threshold of economic transformation and promoting high-quality development is a brand-new practice of economic work under the new historical conditions. To solve a series of difficult problems, scientific theoretical guidance and the spirit of reform and innovation are urgently needed.

　　Since the 18th National Congress of the Communist Party of China, the CPC Central Committee with the Supreme Leader as the core has persisted in observing the general situation, seeking the overall situation and doing practical things, successfully controlled the overall situation of China’s economic development, and formed Socialism with Chinese characteristics’s economic thought of the Supreme Leader in the new era with the new development concept as the main content in practice, which provided scientific theoretical guidance and practical guidance for promoting high-quality development, mainly embodied in seven "persistences": persisting in strengthening the centralized and unified leadership of the Party over economic work to ensure China’s economic development in the right direction; Adhere to the people-centered development thought, which runs through the overall layout of "five in one" and the coordinated promotion of "four comprehensive" strategic layout; Adhere to the adaptation and grasp the new normal of leading economic development, base on the overall situation and grasp the law; Insist on making the market play a decisive role in resource allocation, give better play to the role of the government, and resolutely remove institutional and institutional obstacles to economic development; Insist on adapting to the main contradictions and changes in China’s economic development, improve macro-control, make a choice according to circumstances, prescribe a correct prescription, and take promoting supply-side structural reform as the main line of economic work; Adhering to the problem-oriented deployment of the new strategy of economic development has a far-reaching impact on China’s economic and social development and reform; Adhere to the correct work strategies and methods, strive for progress steadily, maintain strategic strength, adhere to the bottom line thinking, and move forward step by step.

　　These seven "Persistences" cover the political guarantee, purpose, law understanding, system reform, macro-control, strategic layout and working methods of China’s economic reform and development in the new era. They are a systematic induction and summary of the practice of economic reform and development in the new era, fully embody the inheritance and development of Marxist political economy, dialectical materialism and historical materialism, and are a scientific theoretical summary of the practice of central economic work since the new era, which is a very valuable spiritual wealth of the party and the country.

　　Theory originates from practice, is refined above practice, and then guides and promotes practice. This is the methodology of our Marxist political party to promote practice and theoretical innovation. To implement Socialism with Chinese characteristics’s economic thoughts of the Supreme Leader in the new era, we should not only learn documents, speeches and original works, but also accurately understand the spiritual essence and theoretical connotation. More importantly, we should use these important thoughts to guide economic practice and turn scientific theories into high-quality development reality.

　　Since the 18th National Congress of the Communist Party of China, many localities and enterprises, under the guidance of the supreme leader Socialism with Chinese characteristics’s economic thought in the new era, have been brave enough to take responsibility, boldly explore and innovate, and strive to solve practical problems, and have achieved remarkable results and accumulated important experience, which is worthy of good summary, publicity and promotion. These successful cases not only prove the correctness of Socialism with Chinese characteristics’s economic thought in the new era by vivid practice, but also provide a vivid learning model for all aspects to solve practical problems and promote high-quality development. Learning and popularizing these successful experiences is conducive to promoting the ability and level of economic work in all aspects and accelerating the economic development on a high-quality track.

　　Under the unified organization of the Central Organization Department, the Office of the Central Committee of Finance and Economics, together with relevant departments, central media, key universities and cadre education and training institutions, carefully selected 26 typical cases of practicing Socialism with Chinese characteristics’s economic thought of the Supreme Leader in the new era, and compiled "Implementing Socialism with Chinese characteristics Thought of the Supreme Leader in the New Era, Overcoming Difficulties in Reform, Development and Stability, Economic Construction", which was used as a teaching material for the theme education activities of "Do not forget your initiative mind, Remember the Mission". The cases selected in this book cover supply-side structural reform, innovation-driven development, rural reform, regional coordinated development, state-owned enterprise reform, commercial system reform, private enterprise development, urban management, "Belt and Road" construction, free trade zone construction, improving business environment, financial services to the real economy, maintaining energy security and other important fields, and the main bodies of the cases include local governments, enterprises, financial institutions, scientific research units and so on. Each case closely follows the real problems, introduces the successful practices of relevant units, and summarizes and refines some universal experience and enlightenment, which has strong practicability and can be used for reference.

　　The outstanding feature of this set of case teaching materials is to reflect the problem orientation, and each case is aimed at the difficult problems with universality in current practice. For example, how to play the role of the government and the market to promote de-capacity, how to promote mixed ownership reform in large state-owned enterprises, how to improve the business environment, attract foreign investment and promote the development of private enterprises, how to make finance better serve the real economy, and so on. The main unit of each case, under the guidance of the supreme leader Socialism with Chinese characteristics’s economic thought in the new era, works creatively in close connection with its own reality, effectively transforming the universal requirements of the CPC Central Committee into concrete practice of high-quality development. By studying, studying and thinking about these specific cases, leading cadres at all levels engaged in economic work will be vividly educated and inspired, so that they can practice Socialism with Chinese characteristics’s economic thought of the Supreme Leader in the new era more effectively in practical work. Leading cadres engaged in other work will also get useful enlightenment by reading this book.

　　It is the initial intention and mission of the Communist Party of China (CPC) people to seek happiness for the people of China and rejuvenation for the Chinese nation. Economic development is the foundation of social progress, people’s happiness and national rejuvenation. Promoting high-quality economic development is the only way to realize the party’s initial mission. In the theme education activities of "Do not forget your initiative mind, Remember Mission", organizing cadres, especially leading cadres engaged in economic work, to learn these cases is conducive to promoting the theme education activities to go deeper and achieve practical results, so as to promote the vivid practice of high-quality economic development and realize the party’s initial intention and mission.

　　Xinhua News Agency, Wuhan, May 13th: From focusing on water quality to focusing on water ecology — — The Yangtze River "big physical examination" hits directly

　　Xinhua News Agency reporter Li Siyuan

　　"This is a lake area, and there is a risk of contracting schistosomiasis. Don’t touch the water with your arms." At 2 o’clock on the afternoon of May 13th, in Dongting Lake, the middle reaches of the Yangtze River, under the reminder of colleagues, Han Tangrui, a post-90s monitor, pulled up the mud collector from the bottom of the water with his body close to the boathouse. The weight of 40 or 50 kilograms of mud collector and sediment made his face red.

　　Han Tangrui comes from the Ecological Environment Monitoring and Scientific Research Center of the Yangtze River Basin Ecological Environment Supervision Administration of the Ministry of Ecology and Environment, and is also a staff member of the pilot monitoring of water ecological assessment in the Yangtze River Basin in the spring of 2023.

　　The picture shows the monitor collecting zooplankton samples. Xinhua News Agency reporter Xiao Yijiu photo

　　In April this year, under the leadership of the Ministry of Ecology and Environment, the pilot monitoring of water ecological assessment in the Yangtze River Basin was launched in the spring of 2023. Monitoring personnel from the Yangtze River Basin Ecological Environment Supervision Administration and other units will comprehensively monitor the water ecology of 331 points in the main stream, key tributaries and key lakes and reservoirs of the Yangtze River from Qinghai to Shanghai within two months to find out the water ecological base of the Yangtze River and make a "big physical examination" for the mother river of the Yangtze River.

　　According to the job requirements, the main task of Han Tangrui and his colleagues is to collect samples of macrobenthic invertebrates and zooplankton. "These creatures are important indicators of the health of water ecology. Macrobenthic invertebrates, although called ‘ Large ’ In fact, they are not big, some species are only a few millimeters in size, but they are very sensitive to changes in environmental conditions such as hydrology, water quality and climate, and are called ‘ Underwater sentry ’ 。” Han Tangrui introduced.

　　The picture shows that the monitoring personnel are measuring the on-site parameters of water ecological environment. Xinhua News Agency reporter Xiao Yijiu photo

　　In recent years, with the continuous promotion of the great protection of the Yangtze River, the ecological environment protection in the Yangtze River Economic Belt has undergone a turning point, and the ecological environment quality has been continuously improved. "The water quality is constantly improving, and the proportion of water quality section of Grade III exceeds 98%, which means that it is necessary to improve the health of the Yangtze River ‘ Portrait ’ In addition to using traditional physical and chemical indicators of water quality, we have to rely on higher-level water ecological monitoring. " Xu Yi, director of the Yangtze River Basin Ecological Environment Supervision Administration, said that China plans to take the lead in establishing a water ecological assessment mechanism in the Yangtze River Basin, and to establish this mechanism, it is necessary to conduct a comprehensive "physical examination" of the Yangtze River.

　　According to reports, in order to more accurately grasp the water ecological status of the Yangtze River and lay the foundation for the water ecological assessment of the Yangtze River Basin, this year, the Yangtze River Basin Ecological Environment Supervision Administration added two indicators, namely river epiphytic algae and lake phytoplankton, to enrich the monitoring dimension.

　　Xu Wei said that from focusing on water quality in the past to focusing on water ecological changes now, carrying out water ecological monitoring as the "big physical examination" of the Yangtze River is itself progress and innovation, which indicates that the main task of ecological environmental protection in the Yangtze River has shifted from water pollution prevention to equal emphasis on water ecological environmental protection and restoration.

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

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

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

Comparison of three products with "5":

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

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

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

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

Introduction of test platform and description of test method

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

Theoretical test scores:

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

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

● Popular game masterpiece test

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

On the Significance of Game Frame Number (FPS)

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

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

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

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

Platform power consumption test:

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

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

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

Summary of PConline evaluation room:

●GTS250 ladder diagram position guide

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

● What is the value of ●GTS250?

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

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

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

●GTS250 upgrade or purchase suggestion.

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

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

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

The film includes 17 concerts. Martha joked about making a sequel.

　　"Pursuing Dreams in Mayday 3DNA" is the first time for these five people to make a movie. There are many clips of their concerts in the film, and the golden songs are endless. A Xin, the lead singer, revealed: "It feels very fresh to make a movie like this. There are almost 17 concerts in it." Because it is a 3D movie, the camera used in shooting is very advanced, and A Xin also "threatened" that the visual effect of this movie would not be lost to.

　　The three stories in the film were not filmed in Beijing. When asked why, bassist Martha immediately joked, "Maybe the director thinks Beijing is too cold, or maybe the sequel will be filmed in Beijing." Just after that, Martha "repented" again. "Everyone knows that I am the most irresponsible person in May."
