Daning River Ancient Plank Road Relic Site is located in the Small Three Gorges of Daning River in Wushan County, Chongqing City. The Ancient Plank Road relic site is on the West Bank cliff of the Longmen Gorge. There are numerous stone holes arranged in order. The stone holes of the plank road are mostly square in shape, and are staggered in the shape of the Chinese character "Pin". The upper two holes are inserted with wooden piles to support the wooden boards. The lower holes are inserted with wooden columns to provide diagonal support to create a triangular support frame. In this way, a "plank road" fit for human and animal traffic has been constructed. These scenic views are among the supreme examples of the remaining ancient plank roads in China. They reflect the wisdom and greatness of the ancient people.
