Introduction to Zhouqiao: Zhouqiao, also called Denglong Bridge, was built in 1245. It is a single-hole stone arch bridge that runs north-south and spans the quiet Qi River, forming a typical picture of a water town in the south of the Yangtze River. This stone arch bridge is very small, with 13 steps on the north and south sides. The bridge deck is very gentle, so you can walk across it without paying attention.
