Introduction to the Longmen of the Eighteen Liantan Lakes: The original names of the Eighteen Liantan Lakes are Longwan Xiyu and Longwan Dagou. The water from the valleys on the western slope of Shangchi collects the Zhongjunzhang mountain stream and flows into this valley, forming the scene of eighteen consecutive pools. The entire valley is 3 kilometers long. The upper section has a gentle and open terrain, a large drainage area and sufficient water sources; the middle section has a steep terrain, with entangled trees and vines, and lush branches; the lower section of the valley is wide and flat, with strange rocks everywhere. The peaks on both sides are tall and steep, the vegetation is lush, and the cliffs, flowing water, pools and waterfalls are connected. Every step of the way makes people forget to leave.
