Introduction to the former residence: Wang Jinshan's former residence was built in the 19th century. It has an adobe structure and has two floors, two in the front and four in the back. It faces north and south, with a patio in the middle. It is a four-water-pool-style building. The plaque "Former Residence of Wang Jinshan" hangs on the lintel, and two photos of Wang Jinshan are placed on the incense table in the room.
