Introduction to Yuliang Dam: Yuliang Dam is a short dam built on Lianshui, a tributary of the Xin'an River. The Lianshui, a tributary of the Xin'an River, flows through here. Due to the natural drop of about two meters in the terrain, it is difficult for boats to sail. This caused great inconvenience, so the locals built a rolling dam here according to local conditions. It can not only store water upstream for irrigation and navigation, but also slow down the flow below the dam for flood control.
In order to protect the dam body, boatmen have always been unable to sail beyond the dam. Therefore, the boats coming from the upstream ended when they reached Weiliang Dam. If they wanted to go downstream, they had to transfer boats from here. Therefore, a small town - Weiliang Dam gradually grew up here. ancient town.
