Yuliang Dam is located in Yuliang County, Shexian County, Anhui Province. It is the oldest and largest ancient dam in the upper reaches of Xin'an River. It is the most well-known water conservancy project in ancient Huizhou and is called the Dujiangyan of Huizhou. Yuliang, once a brilliant Huizhou businessman, arrived at Qiantang. Xiayangzhou must start from here. Hu Xueyan, the place where Huizhou businessmen began their dreams, went to the commercial road from here. Nowadays, the winding blue stone streets of Yuliang Village and the rows of old houses on both sides testify to the prosperity of the Huizhou merchants in the past.
