Introduction to Longquan Pool: There is a cedar forest in the southwest of Daming Lake. Among the dense shade, there are five pure pools arranged meandering from west to east. The easternmost pool reaches directly to the lake shore. The clear spring water overflows from the west pool and flows eastward into the other four in turn. The pool is injected into the lake from the East Pool; the bank of the pool is made of natural stones. At the connection between the pools, flat bridges, lying water arch bridges, Tingbu bridges across the water and natural rolling dams are built for tourists to enjoy. For playing in the water, there is a small island in the pool. The island is full of fragrance of flowers, simple and natural scenery, and has the beauty of spring forest. Therefore, the spring water here is drawn from Wulongtan, so it is named "Longquan Pool".
