Site of the Fushan Weir in Sihong

The Site of the Fushan Weir in Sihong is a cultural tourism attraction.

The site of the Fushan Weir is located to the south of Tonghe Village, Sihexiang, Sihong County, with the surviving section now situated on the riverbed of the Huai River. According to the Qing Dynasty’s Guangxu-era *Sihong Combined Chronicles*, in the 11th year of the Tianjian era of the Liang Dynasty (514), Emperor Wu of Liang built the 4.5-kilometer-long Fushan Weir on the Huai River to resist an invasion from the Northern Wei and to flood Shouchun. The *Book of Liang* records that the Fushan Weir project was massive, employing 200,000 workers and taking two years to complete. The weir stretched 9 li in length, with a base width of 140 zhang, a top width of 45 zhang, a height of 20 zhang, and a depth of 19.5 zhang. The remaining section today stretches approximately 300 meters, constructed from compacted yellow earth, and is 15–50 meters wide and about 4 meters high. Excavated artifacts include bronze arrowheads and iron swords. The weir's profile consists of layers of rammed earth, and the surviving remnants are well preserved. The Fushan Weir site holds significant value for the study of ancient hydraulic engineering, warfare, and military infrastructure.
