The building can be from the south of the mountain. This is a four-storey building. It is facing north and south. The lower floor is a stone platform. There is a patio. There are arch coupon gates on both sides of the north and south. It is a passage for pedestrians in the old times. The south gate is written on the book "Gulumen", and the north gate is titled "Guimen". The word is as big as a bucket, which is Zhu Ying's handwriting.
