Thousands of loyal souls forged a turning point, and the army made a long march of a thousand li into the Dabie Mountains. Starting from August 7, 1947, after the victory of the Battle of Southwest Shandong, the army led by Liu Bocheng and Deng Xiaoping, without taking a rest, quickly shook off several routes of the Kuomintang troops that were about to encircle them. They advanced rapidly southward in three columns and made a long march of a thousand li into the Dabie Mountains.  

As time passes and the times change, the smoke of gunpowder on the battlefield has gradually dissipated with the passage of time. However, when we look back on history, the heroic deeds of the army led by Liu Bocheng and Deng Xiaoping on the land of Yuzhou still make our hearts surge with excitement. The "River Crossing Spirit" is deeply ingrained in the blood of this red land, igniting the fighting spirit of future generations and also inspiring the passion of Diheng China's partners. On the occasion of the 73rd birthday of our motherland, Diheng China's partners used Diheng's ace product DU6100 in the 6,000-lumen range to cooperate with the memorial halls to create light and shadow exhibition items. With the two "halls" (the Memorial Hall of the Army Led by Liu Bocheng and Deng Xiaoping Crossing the Huai River and the Memorial Hall of the Army Led by Liu Bocheng and Deng Xiaoping Crossing the Yellow River) acting in unison, we commemorate and experience the eventful years when the army led by Liu Bocheng and Deng Xiaoping advanced into the Dabie Mountains through light and shadow, presenting a gift for the National Day. High-quality products are Diheng China's most sincere commitment to the market and its partners. Diheng's DU6100 has a built-in edge masking function, which can be used to project images on screens of special shapes (such as curved screens or spherical screens). This technology makes the projection methods more diverse. Different designs can be made according to the projection theme and the style of the venue to create more creative imaging, meeting the various scene requirements of the memorial hall. The Memorial Hall of the Army Led by Liu Bocheng and Deng Xiaoping Crossing the Huai River is located on the banks of the Huai River in Xixian County, Xinyang City, Henan Province, a national 3A-level red tourism scenic spot. It is a venue that integrates cultural display, ecological landscape, and leisure and recreation, where red commemorations blend with the history of Xixian County.  

The theme of the interior exhibition layout of the memorial hall is "A Red Cultural Journey Through Time and Space". Closely following the revolutionary history of Xixian County, the combination of sound, light and electricity is used to recreate the historical chapters of the army led by Liu Bocheng and Deng Xiaoping making a thousand-li leap forward, forcing their way across the Huai River, and advancing into the Dabie Mountains. The optoelectronic display device used is the Diheng DU6100. The misty walls surrounded by clouds and mists, the water curtain projected through the magic flow screen, the continuous images and the intense sounds of gunfire and explosions immerse people in the scene, giving them a feeling of being personally on the scene. It seems to enable people to travel back to that historical moment in the present time and space, and witness the heroic feat of forcing their way across the Huai River with their own eyes.

The design team of the Memorial Hall of the Army Led by Liu Bocheng and Deng Xiaoping Crossing the Yellow River has gained an in-depth understanding of the immortal feats achieved by the army led by Liu Bocheng and Deng Xiaoping when they forced a crossing of the Yellow River. With a practical and realistic scientific attitude and superb design skills, they have used Diheng's DU6100 digital multimedia, as well as sound, light and electricity technologies to upgrade the exhibition layout of the memorial hall to a high standard. They have presented a magnificent "Memorial Hall of the Army Led by Liu Bocheng and Deng Xiaoping Crossing the Yellow River" on the land of northern Henan Province, which has a long history and rich cultural heritage. This vividly reproduces the moving scene of the army led by Liu Bocheng and Deng Xiaoping forcing a crossing of the Yellow River, as well as the deep affectionate bond between the people in the old revolutionary base areas and the People's Liberation Army soldiers during the war years.  

The completion of one memorial hall after another has given rise to the era of Diheng DU6100 as the king of projectors. Now, it has fulfilled its historical mission as the king of its generation and withdrawn from the market. The newly iterated product, Diheng DU6200, will take over and complete the future mission. Diheng DU6200 inherits the consistent aesthetic characteristics of Diheng projectors. The meticulous craftsmanship of Diheng is reflected in every corner of the machine. The body of the machine is lighter than its previous generation, DU6100 (weighing only 7.7KG), and it is easier to install. The body can perfectly blend into different scenes and integrate with the environment, making the audience's viewing experience more realistic. At the same time, DU6200 supports 4K input, and its color processing is more vivid and bright. It enjoys a multi-lens configuration, and one machine can switch different scenes and provide different visual experiences, covering all aspects. As important resources carrying the magnificent revolutionary history of the Communist Party of China, the arduous struggle history, and the moving hero history, red resources contain the lofty ideals and firm beliefs of Chinese Communists. They are an important part of the socialist core value system and a vivid teaching material for the education of world outlook, outlook on life, and values.

Whether in commemorative exhibition halls, cultural and tourism night tours, light and shadow restaurants and other scenarios, the new generation of DU6200 can easily handle them, and it will continue to carry forward the glory of the previous generation. As a national brand, Diheng China will always uphold a positive and innovative attitude, explore new application fields, and contribute to the development of the light, shadow and physical display industry.
