Introduction to the Thanksgiving Archway: The Thanksgiving Archway is composed of six pillars, five doors, seven domes, and double hanging flower columns. The two characters "Thanksgiving" are written on the central plaque, and "Yun Wen Yun Wu" and "Nai" are written on both sides. What is pure is true.” Because the Yellow River Altar was built in the Ningxia Hui Autonomous Region, the Thanksgiving Arch uses some symbols of Islamic architecture to express the common gratitude of the Hui Han people to the mother river of the Yellow River, and also to imply that the Chinese nation is a big family of fifty-six ethnic groups. Gratitude to the Yellow River, the mother river, is the common aspiration of the Chinese nation: to build a spiritual homeland that is jointly built, shared and shared by the Chinese nation.
