Sanjiang County in particular is famous for the stockade villages built by the Dong ethnic minority. The Dong people also erect covered bridges with porches and pavilions which provide shelter even when it rains. The local people call these types of bridges by a beautiful name - 'Wind and Rain' bridges. Of them, the Chengyang Wind and Rain Bridge is the most famous.
Chengyang Wind and Rain Bridge, also called Yongji Bridge or Panlong Bridge, spans the Linxi River of Sanjiang County. Built in 1916, it is 64.4 meters (73.43 yards) long, 3.4 metes (3.72 yards) wide and 10.6 meters (34.78 feet) high. Constructed with wood and stones, the surface of the bridge is paved with wooden boards and both sides are inlayed with railings. On the bridge itself, there are five tower-like kiosks with 'horns' and eaves which resemble the flapping wings of birds.
To one's surprise, the builders of this bridge did not use any nails or rivets. Instead, talented Dong people dove-tailed many pieces of wood. Though several decades old, the bridge is still very sturdy. In a word, it is grand and looks like a brilliant rainbow crossing over the river.
