Introduction to Wanli Bridge: Wanli Bridge is the most famous and oldest bridge on Ling Canal. As the only way to travel between north and south in the past, it was historically known as the "important bridge between Chu and Yue". The Wanli Bridge was built in the first year of Baoli (825 AD) by Li Bo, the Guiguan observer at that time. It was originally a rainbow-style single-arch bridge with only one layer of ax blade stone. There was a Jieguan Pavilion five miles north of the bridge. On the south bank are the article "The Story of the Bridge of Ten Thousand Miles" written by Wu Yu, a talented man from the Ming Dynasty, and the stone tablet "Feeling Home for Thousand Miles".
