Introduction to the Yinxin Stone House: The Yinxin Stone House is a Chinese-style garden building. During the Taiping Heavenly Kingdom, it was a watchtower in the palace of the Celestial Dynasty. It is about 10 meters high and open on all sides. You can climb the tower to have a panoramic view of the palace. What we see now is that it was rebuilt after destruction and has lost its observation function. In the house are embedded the "Complete Landscape Map of Zijiang Yinxin Stone House" and a stele of gratitude from Emperor Daoguang.
