Introduction to the Mani Palace: The Mani Palace was built in the fourth year of Emperor You of the Northern Song Dynasty (1052). It is the existing palace with the highest historical, artistic and scientific value in Longxing Temple. The hall is in the shape of a cross in plan, with a mountain-like building with mountain flowers facing forward in the middle of the four sides. The main body of the building is full of changes and has clear priorities. It is the only example of the existing Song Dynasty architecture in my country. It was hailed as an isolated example of ancient architecture in the world by Mr. Liang Sicheng, an expert on ancient architecture.
