Jishan Hall, also named the 4th hall, was built in the Qing Dynasty by Wu Shutai (1807-1850), the 31st generation of the Wu family, but it was destroyed in the modern era. The name is taken from Zhouyi Xicishangzhuan: “It is good that one inherits the Dao in the natural order of things, but it is in the process of embodying it, that one’s character is formed”. It also makes reference to The Book of Songs: The son who is blessed will be laid in a sweet bed, dressed in a fine robe and he will play with jade.” The word “nongzhang (play with zhang)” makes reference to the idea that the ancients gave zhang to a child to play with in the hope that he would have jade-like virtues in the future. “Zhang 璋” itself refers to the round top of a jadeware object with a square bottom, called gui.

There are two remaining courtyards with a foyer, a front yard, a principal hall and a back yard on the central axis, and two-storey Xiangfang on the left and right of the front courtyard and back courtyard. The two-storey principal hall is two rooms wide.
