The Grand Canal in Sui and Tang Dynasties flows through Henan, Anhui and Su Sansheng, and the distance in Anhui is over150km. Yang Di dug the Grand Canal to connect the economic canal to Henan, passed through Huaibei, Suzhou and Sixian in Anhui, and entered the Huaihe River in Xuyi, Jiangsu. The Sui and Tang Grand Canal in Anhui Province has been silted up except for a few sections that are still being rebuilt and used. At present, the only "surviving" site of the Sui and Tang Grand Canal is located in our county, starting from the junction of Tanghe River in the west, crossing Sicheng and reaching He Sui in the northeast, with a total length of about 25 kilometers. The site basically maintains the original appearance of the Tongji Canal of the Sui and Tang Dynasties, and its function has changed, but it can still play the role of irrigation and flood diversion.
