Introduction to the main hall: There is a 1 meter wide and 1.5 meter high stone wall surrounding the main hall. In the center of the south wall is a tall mountain gate with a green glazed tile roof. The two doors are vermilion red, with large golden mushroom-shaped copper nails nailed on the doors. Entering the mountain gate, there is a yurt-style circular building on the west side and a sacred horse stable on the east side. The entire building is symmetrical and harmonious, and can be described as a treasure of architectural art.
