Introduction to the Traceability Bridge: The Traceability Bridge is a three-hole stone bridge, divided into three bridges, one main bridge and two guest bridges, for a total of three roads and nine holes. The railings on both sides of the bridge are combined with elegant rolling curves, and the column heads are engraved with dragon patterns along the entire body, creating an elegant and graceful shape. The three characters "Tuyuan Bridge" are the fonts of Yi Bingshou, a great calligrapher of the Qing Dynasty who was born in Ninghua.
