Formerly known as Yishen House, it was once hung with the plaque of "Yishen House" written by Emperor Kangxi. It was a place for the master of the house to entertain guests and set up banquets and watch operas. With an area of 685 square meters, it is a mortise-and-tenon building structure. The four walls and beams are painted with purple vine flowers and branches, giving people the feeling of watching the opera under the vine stand.
