Introduction to the Kangxi Twin Bridges: The Kangxi Twin Bridges are located on the lower west side of the old locust tree in the ancient village. They are divided into east and west bridges, about ten meters apart. The East Bridge was built in the ninth year of Kangxi (1670), and the West Bridge was built in the twenty-seventh year of Kangxi (1688), more than 300 years ago. It is very convenient for pedestrians to get up and down. The bridge body is entirely made of bluestone. Although it does not use mortar, it is still strong despite wind, rain, snow and frost. It is praised by experts as "the prototype of a modern overpass".
