Introduction to Duanmen: Duanmen is the first gate of the main temple. It was built in the Qing Dynasty. When passing through, "civilians must dismount their sedan chairs and military attachés must dismount their horses." The end door is made of brick. On the top of the mountain, imitation wooden bricks and brackets are placed under the eaves. There is a giant iron lion on the east and west sides of the door. Below the iron lion is a rectangular Xumi-style base with an upper section of two meters. It is powerful and majestic, and its scale is the largest among the iron lions in the whole temple.
