Shen Wansan's former residence Shen Hall has three parts. The front is the water wall door and the river, which are specially for the family to dock ships and wash clothes. It is a special building in Jiangnan Water Township; the middle is the wall door building, tea hall, and main hall. It is a place to pick up and drop off guests and handle weddings and funerals and discussions. The back is the lobby building, the small hall building and the back hall house, which is the place of living. The whole hall is a typical "front hall and back hall" architectural pattern. The front and back buildings are connected by the cross-street building and the aisle pavilion, forming a circular walk-horse building, which is rare for similar buildings.
