Introduction to Sanfeng Bridge: Sanfeng Bridge is located at the end of Baozhu Village, also known as Long Bridge. It is 37 meters long, 13 couplets, 6 meters wide and 4.5 meters high. Experts prove from the carvings on the beams such as dragons' mouths and phoenix bodies that the bridge was built in the Ming Dynasty and rebuilt in the 18th year of Jiaqing in the Qing Dynasty (1813). The wood of the bridge body is of its original color. It is clean and dust-free, and there are no spiders or insects attached, which is really rare. The entire bridge has a raised beam structure, and the tenons are connected without bolts.
