Ji-Shan-Tang
“Ji-Shan-Tang” (Jishan Mansion) was built by the brother of Zheng Guanying. Its main hall on the 2nd floor is smaller than that of “Yu-Qing-Tang” (Yuqing Mansion). Rooms are located on its two sides. It is said that some descendants of the Zheng family had lived here, having been responsible for rental and management affairs of the house.
