Introduction to the rockery: The rockery is located in the south of the west courtyard. There is a four-cornered pavilion built on the mountain, and a cave is built at the foot of the mountain. Visitors can climb the mountain to overlook the distance, and enter the cave to explore, which is full of fun. There are many gardens in the south of the Yangtze River, and their outstanding feature is that many of them contain Taihu stones. Garden rockeries are made of countless Taihu stones that are skillfully assembled and stacked artificially.
