The meandering Yellow River, with its indomitable majestic momentum, has shaped the Chinese nation’s national character of self-improvement and is an important foundation for the Chinese nation’s firm cultural self-confidence.

　　General Secretary of the Supreme Leader pointed out that it is necessary to promote the systematic protection of the cultural heritage of the Yellow River and protect the precious heritage left by our ancestors. It is necessary to deeply explore the value of the times contained in the Yellow River culture, tell the story of the Yellow River well, continue the historical context, strengthen cultural self-confidence, and gather spiritual strength for the Chinese dream of realizing the great rejuvenation of the Chinese nation.

　　Following this, the sons and daughters of the Yellow River compose the "Yellow River Chorus" in the new era.

　　Through the dance language, it tells the changes of Hehuang and shows the mother river that nurtures the Chinese culture of "multiple symbiosis, integration and co-construction". On September 5th, the performance season of the original dance poem Hehuang ended successfully in Qinghai Grand Theatre.

　　"There are ten performances and the venue is full." Shi Honggang, the producer of Hehuang, said. In the middle and late October, Hehuang will try to tour in nine provinces along the Yellow River.

　　For thousands of years, it has been rushing. Yellow River culture is an important part of Chinese civilization. In China’s 5,000-year history of civilization, the Yellow River Basin has been the national political, economic and cultural center for more than 3,000 years, which has nurtured Hehuang culture, Heluo culture, Guanzhong culture and Qilu culture, distributed in ancient capitals such as Zhengzhou, Xi ‘an, Luoyang and Kaifeng, and produced the "Four Great Inventions" and classic works such as The Book of Songs, Laozi and Historical Records.

　　In 2023, there were several important "100 years" in the cultural history of the Yellow River:

　　At the international academic conference on the centenary of the discovery of Shuidonggou site in August, Gao Xing, a famous archaeologist, said that this was the beginning of Paleolithic archaeology in China, which corrected the assertion that there was no Paleolithic culture in China.

　　The International Forum on the centenary of the discovery of Hetao Man held in Wushenqi, Erdos City, Inner Mongolia in August pointed out that this place is an ancient post station in the history of human development and an important root vein of human civilization.

　　This year marks the 100th anniversary of the discovery of the Lotus Crane Square Pot, the "swan song of the Bronze Age". On August 25th, the centennial unveiling ceremony of bronze relics unearthed from Zhenggong Tomb in Lijialou was held in Xinzheng, Henan. "The Lotus Crane Square Pot shows the long history and profoundness of Chinese civilization, which is of great significance for strengthening cultural self-confidence and inheriting Chinese context." Ren Wei, director of the Henan Provincial Cultural Relics Bureau, said.

　　Li Qun, director of National Cultural Heritage Administration, said that major projects such as the Chinese civilization tracing project show that Chinese civilization has undergone changes in time, space, dynasty, social nature, etc., but the form of civilization has not broken, and the civilization has a long history. Agriculture, jade, capital construction and other elements of civilization all show a clear inheritance relationship.

　　In early autumn, on the south bank of Huan River, Yin Ruins greeted tourists from all directions. More than 100 years ago, Oracle Bone Inscriptions was found here, and China believed in prehistory for thousands of years.

　　Oracle bones contain context. Oracle Bone Inscriptions laid the foundation for the method, square shape and development framework of Chinese characters, which has evolved for more than 3,000 years without changing its shape, and has become the spiritual bond of Chinese sons and daughters.

　　Song Zhenhao, a member of the Chinese Academy of Social Sciences, said that Oracle Bone Inscriptions’s "supplementing history with classics" is the common cultural memory of the Chinese nation.

　　"In ‘ Yin qi Yuan Wen ’ Oracle Bone Inscriptions Big Data Platform, ‘ Great Oracle Bone Inscriptions ’ In addition to the interactive applet, we are studying the automatic conjugation and auxiliary interpretation of Oracle bones through artificial intelligence. " Liu Yongge, director of the Key Laboratory of Information Processing in Oracle Bone Inscriptions, anyang normal University, said.

　　Ren Fengyun will still be full of vitality, and the Yellow River is ancient and evergreen.

　　On September 8th, the "Harmony of Rivers: 2023 Intangible Cultural Heritage Exhibition Week along the Yellow River Basin and the Grand Canal" was launched in Weifang, Shandong. 183 non-legacy projects and 280 non-genetic inheritors participated in the exhibition along the Yellow River and Kowloon Provinces.

　　"Taishan does not let the soil, so it can become a big one; Rivers and seas do not choose small streams, so they can be deep. "

　　The Yellow River culture is transformed and regenerated in the revolutionary tradition.

　　"Two Bombs and One Satellite" Spirit, Long March Spirit, Yan ‘an Spirit, Luliang Spirit, Taihang Spirit, Hongqi Canal Spirit, Jiao Yulu Spirit, Yimeng Spirit … … A big river bears witness to the majestic power of single spark can start a prairie fire, the Communist Party of China (CPC).

　　"send Kunlun five-color flow, a yellow turbidity through Zhongzhou." It is our common belief that the country is inseparable, the country is inseparable, the nation is inseparable, and civilization is inseparable.

　　The Yellow River has nine bends and eighteen bends, and the last bend before entering the sea is laid in Lankao, Henan.

　　When you walk into Xuchang Village, Guyang Town, lankao county, you will see a striking village sign: a giant pipa made of bricks and tiles. Once a national poverty-stricken village, it has become a well-known musical instrument village.

　　Paulownia lankao has loose wood and is not easy to deform, so it is a good material for making national musical instruments. "Since the 1980s, villagers have taken local materials and started to make musical instruments and open music workshops." Xu Yongshun, a village cadre, said that at present, the annual output of guzheng, pipa, guqin and other musical instruments in the village exceeds 100,000.

　　In 2022, Lankao was rated as "the hometown of China’s national musical instruments", and the output value of the national musical instrument industry in the county reached 3 billion yuan, and tens of thousands of people ate "musical instruments".

　　Paulownia is silent, and the rhyme is around the beam. The "Jiao Tong" planted by Jiao Yulu himself has been graceful. This is Lankao’s "Happy Music", which is a Yellow River cultural sonata to help the world.

　　The Yellow River Basin is rich in cultural resources. According to statistics, there are more than 300,000 immovable cultural relics in 9 provinces and regions of the Yellow River Basin, about 900 national intangible cultural heritage representative projects, more than 2,000 national key cultural relics protection units and more than 7,300 provincial cultural relics protection units.

　　For a long time, these cultural heritages have been relatively scattered and independent, and the system and mechanism of cross-regional and multi-sectoral participation are not perfect. It is difficult to unify the interpretation, systematic protection and comprehensive utilization of the Yellow River culture, and it is urgent to need a "grand blueprint".

　　We only have one Yellow River, and the situation of "fighting alone" in the cultural protection of the Yellow River in various places is undergoing fundamental changes.

　　The "14th Five-Year Plan" outlines the construction of national cultural parks such as the Great Wall, the Grand Canal, the Long March and the Yellow River.

　　The Outline of Ecological Protection and High-quality Development Planning of the Yellow River Basin proposes to systematically protect the cultural heritage of the Yellow River, deeply inherit the cultural genes of the Yellow River, tell the story of the Yellow River in the new era, build a cultural tourism belt of the Yellow River with international influence, and plan to build a national cultural park of the Yellow River.

　　Recently, the Protection Plan for the Construction of the Yellow River National Cultural Park was officially issued. This is a major project to further protect, inherit and carry forward China’s excellent traditional culture after the Great Wall, the Grand Canal and the Long March National Cultural Park, and it is a major measure to promote the ecological protection and high-quality development of the Yellow River Basin.

　　On April 1st, the Yellow River Protection Law was officially implemented. For the first time, China incorporated the promotion and inheritance of water culture into basin legislation, and incorporated cultural attributes into the connotation of the basin, highlighting the root of Chinese traditional culture in which man and nature coexist harmoniously.

　　"A month of closing the river can lead to Wan Li’s feelings." The culturally confident "Yellow River Chorus" is singing loudly.

　　Big River Mind: and oceans drain the golden river

　　On September 6, more than a thousand representatives from more than 50 countries and regions gathered in Dunhuang. With the theme of "Connecting the World: Cultural Exchange and Mutual Learning of Civilizations", the 6th Silk Road (Dunhuang) International Cultural Expo opened in Dunhuang.

　　Over the past 40 years since its premiere, Silk Road Flower Rain has performed more than 3,800 performances in more than 40 countries and regions, with an audience of more than 5 million people, creating a Guinness World Record for dance drama.

　　Music and dance are the common language of human beings. The United Nations issued stamps reflecting the art of the disabled, and the dance "Thousand Hands Guanyin" by the China Disabled Art Troupe was selected. From Rain on Silk Road to Avalokitesvara with Thousand Hands, the inspiration comes from Dunhuang, Yungang and Longmen. Grottoes art originated from Tianzhu, which has been carried forward in China, has gone over the Taihang Mountains, the Central Plains and the Yangtze River.

　　"Behind the grottoes is a culture with a distinctive open and inclusive temperament." Song Zhiqiang, secretary general of Datong Ancient City Protection and Restoration Research Association, said.

　　Kindness and kindness to neighbors, harmony and all nations. From Yao Shunyu’s abdication system, to the "harmony" of Oracle bones and inscriptions in Xia, Shang and Zhou Dynasties, and then to the concept of "harmony without difference" and "turning an arm into a jade" in the Spring and Autumn Period and the Warring States Period, the Yellow River culture has shaped China and influenced the world with its outstanding peace.

　　　　"Depend! I forgot to bring my mobile power when I went out today! " For today’s smart users, the importance of mobile power is almost flush with the mobile phone itself, and the battery life performance of the mobile phone is particularly important in such an "era". However, aside from these accessories, some mobile phone manufacturers preset a "super power saving" power mode for their mobile phones. In this mode, in addition to some connection functions being disabled, the screen of the mobile phone becomes black and white. Today, we are here to test whether the screen display color is dark or not.

Mythbusters series? AMOLED/IPS screen power consumption test

　　　　I believe many friends have seen it on the Internet or heard it from friends. Setting the screen to a dark or black background can help save electricity, and as mentioned at the beginning, manufacturers will also set some themes to extend battery life, mainly in black and white. This should be a more reliable statement, and the author should be more serious in a responsible attitude. Of course, the greeting in the title is also to add some suspense to the whole article, and the netizens in the province already know the answer before reading the article.

　　　　Of course, as a contrast, our article contains two screen types that occupy the mainstream market, namely AMOLED and IPS. As a screen, the display principles of their two screens are really very different, so let’s start with a little science on screen knowledge at the beginning of the article.

Arranged into a displayed picture by displaying pixels of three primary colors one by one (the picture comes from techeblog).

Liquid crystal screen structure (picture from Kisplay)

　　　　First of all, we should know that at present, all color display devices use the three primary colors of red, blue and green for synthesis, and another key point is the pixel, which is also the key to what we call the clarity of the mobile phone screen and so on. In fact, the IPS screen we are talking about is essentially the same as the TFT screen, both of which belong to the LCD screen, and the IPS panel is superior to the TFT in display characteristics because of the different technologies for controlling the deflection of the LCD, which has become the mainstream screen in the current mobile market (others are TN panel, MVA panel, etc.). Since the structure is the same, I can see from the above picture that it is the backlight that really makes us see the color clearly, which is also the root of the problem of light leakage that many people talk about.

OLED structure (picture from oledw.com)

　　　　On the other hand, AMOLED screens are very different in structure and lighting mode. In fact, OLED technology was rarely applied to civilian-grade products before the smart phone boom, and many AMOLED and Super AMOLED screens from Samsung made people slowly come into contact with OLED technology. Organic light-emitting diodes with dyes in OLED can emit by themselves.Colored light, undertakes the mission of "backlight+filter", which has a huge gap with LCD screen in the use of light.
