Introduction to Lanzhou Holding Bridge: Lanzhou Holding Bridge, also known as Lying Bridge, was one of the "Eight Scenic Spots of Lanzhou" in the past. The bridge body of the Holding Bridge is made of giant wood. It stretches forward from the two banks toward the center of the river, layer by layer, connected jointly, and takes on the shape of a dome. There are arcades on the bridge deck to provide shelter from wind and rain; the railings on both sides are neatly arranged; There are wing pavilions at both ends of the bridge, which look like two fists clenched, hence the name Holding Bridge.
