Introduction to the mountain gate: The mountain gate faces south and consists of a Tibetan-style city platform and a Chinese-style verandah. The city platform is a masonry structure with a three-hole arch in front. There is a row of blind windows on the arch and a pheasant saucer built on it. There is a verandah on the city platform, with corridors at the front and back. The corridor has built-in sill windows and sealed walls on both sides. It is five couplets wide and two rooms deep. It has a single-eave glazed tile roof with green glazed tiles on the edges. In the middle is the guardian deity, from left to right. In order, they are the four-sided Dharma protector, the Dharma protector Zhanggruupong, and the Dharma protector Mahakala Mahakala. There is a pair of stone lions in front of the mountain gate, and a five-hole stone bridge to the south. There are waist gates on both sides of the mountain gate and are connected by walls.
