I came to Shiyangxi, south of Xidong Village, Shiyang Town, Taishun County, Zhejiang Province. I saw a special bridge built on the stream of the river. This bridge is not the same as the usual bridge we usually see. It is made of many stones. The stones are not connected to the stones. The passers need to cross the stones one by one. To pass, this bridge is the prototype of the current bridge, known as the "Bridge Bridge." Taishun Liaobu Bridge has a large number of branches and a long history. Among them, the Shishui Biaobu Bridge on the Shiyang River is a two-story dyke bridge. The Liaobu Up and Down Creek Bed has a large area of well-shaped wooden frame framed cobblestone foundation. In order to stabilize the pace, a total of 223 teeth, a total length of 136 meters. Shishuiyubu Bridge is divided into two high and low roads. The high ones are for the shoulders to walk, and the low ones are for the general pedestrians. Because the high trail material is granite and the low trail material is bluestone, it will show a black and white scene in the moonlight. It resembles the piano's black and white keys, so it is called "bridge" by the locals.
