Introduction to Guanling Pond: The lakeside is covered with cattail grass, wild ducks roam, and kingfishers sing; carp dive into the bottom of the water, and goldfish float on the surface, like a red carpet. The rippling blue water in Jiutian Garden sets off and complements each other with the native lake upstream, like the eye of the sky, the mirror of the moon, and the home of the stars.
