The Tianlou is said to have been built during the reign of Qianlong in the Qing Dynasty. From the distant hill, it looks like an Eight-Diagrams structure, and from the nearest, it looks like a circular building. The whole building has three floors. The bottom wall, nearly two meters thick, is quite spectacular. There are two gates around the house. The name of the triangular pond "Sanyuan pond" behind the building is clear and visible.
