Bamian Hall in Huangshan village, Yiwu, originally called Zhensheng Hall, was completed in 1813 after 18 years' of construction work. There are eight halls, seven courtyards, eight flagpoles and eight gateways around its external wall, hence the name Bamian (eight-faced) Hall.

The architecture is that of a typical Qing Dynasty (1644-1911) residential building in the area south of the Yangtze River, which combines the functions of an ancestral hall and residential dwellings. It is situated in the southwest, faces the northeast, and covers 2,908 square meters.

The main building and affiliated buildings of the hall are composed around one central axis and two transverse axes, forming a unique layout. Halls, gardens, lobbies, and saloons are distributed along the central axis. They are places where the Chen family held sacrifices, gatherings and various ceremonies. Two three-way courtyards on the north and south sides of the transverse axis contained housing for the Chen family.

The designer located the garden in the front of the whole complex, which is different from the traditional way in Chinese architecture. The layout of the complex is like two rectangles, with the bigger one enclosing the smaller one. It was built with high-quality materials and is full of exquisite sculptures in both the actual structure and the decorations, such as a domed arch, doors and windows, beams and pillars.

It is also famous for stone, brick and wood carvings, and shows the rich cultural connotation, skillful carving techniques, high artistic value and craft value of the architecture.
