And Diheng is also honored to add impetus to Tianshui's cultural and tourism industry and empower the night economy of this newly emerging internet-famous city with profound cultural heritage. The Hometown of Xuanyuan in Tianshui is located in Qingshui County's new urban area, Tianshui City, Gansu Province. It is a national AAAA-level tourist attraction, a national intangible cultural heritage site, and a landmark cultural area for the inheritance of Chinese civilization in Gansu Province. The Xuanyuan Lake is like "a bright pearl" in the scenic area of the Hometown of Xuanyuan.  

The Xuanyuan Lake water curtain projection project implemented by Diheng in cooperation with its partners combines sound, light, electricity, and fountains. It vividly restores the life and main achievements of Xuanyuan Huangdi (the Yellow Emperor) in the form of projection. Scenes such as hunting, farming, pottery making, cart making, observing the sky, battles, and offering sacrifices to the heaven... Each scene is dreamlike and of great momentum.  

The project selects Diheng's Lyra DU22K model, which has a high brightness of 22,000 lumens. It uses Nichia MCL laser light source and DLP projection technology, with a WUXGA physical resolution. It supports 4K image quality, making the picture more delicate. It has built-in lattice calibration and edge fusion functions, making the project application more flexible. The sudden popularity of Tianshui may not be truly "sudden". With nearly a thousand years of historical accumulation, this city has the capital to become popular. With the support of traditional culture and the rapidly developing online media, the questions now are: how to maintain the "fiery freshness" and how to retain the popularity?  

"Drive the line with a point, and drive the area with the line." Using the "viral point" to boost the cultural and tourism industry, and then using the cultural and tourism industry to drive the urban economy has become an inevitable path. Therefore, breaking through in the cultural and tourism field is the key. And the cultural and tourism night tours featuring light and shadow are precisely the sharp tool to break the deadlock. By combining projections with local characteristics, a new business district with a strong atmosphere can be created at night. For example, rural night tours, cultural and tourism towns, water curtain shows, city wall shows, etc., can all effectively retain tourists at night, and restart the booming daytime economy in the evening.  

Diheng is also constantly researching, developing, and expanding on the product end of projection equipment for cultural and tourism night tours and in the aspect of industry applications. The cultural and tourism models with a brightness range from 10,000 lumens to 32,000 lumens have received widespread acclaim during extensive applications. In order to develop the regional night economy and contribute to China's cultural and tourism industry, Diheng is forging ahead with perseverance.
