Introduction to the Qutan Palace: The Qutan Palace was built in the 26th year of Hongwu in the Ming Dynasty. It is one of the main buildings of the temple. It is located in the middle of the central courtyard, five bays wide and four bays deep, with an area of ​​300 square meters and double eaves. Rest on the top of the mountain. The layout is unique. There are three deep Baoxia rooms on the front eaves, thick walls on the left, right and back sides, and a sandwich wall inside the outer wall to form a circle of secret corridors. This is a common pattern in Tibetan Buddhist temples.
