Introduction to Ruyi Lake: The clear water surface that can be seen from afar while standing on the Wangjing Terrace. The fountains in the lake spray out scattered water splashes, hitting the lake surface with a tinkling sound. The water flows slowly along the laminated water wall. Falling, accompanied by the lotus swaying in the wind in the lotus pond, and the clumps of purple amaranth, it shows the beautiful lakeside scenery. In summer, tourists stand on the water-friendly platform in the lake area, looking at the bright moon and listening to the sound of water. It is very of leisure and comfort.
