The Wind and Rain Bridge is a unique minority architecture of Dong people, an ethnic group in south-western China. The most famous of these bridges is Chengyang Wind and Rain Bridge. The bridge is a combination of bridge, corridor, veranda and Chinese pavilion. The piers are made of stone, the upper structures are mainly wooden, and the roof is covered with tiles. The bridge has wooden handrails on both sides. No nails or rivets are used. Instead, talented Dong people dove-tailed many pieces of wood. The bridge is located in Chengyang, and serves as the link between two populous villages.
