Crescent Lake is located 1 km west of Gaotai County, Zhangye, and is known as "Little Jiangnan". The entire lake is curved and shaped like a crescent, hence the name Crescent Lake. Crescent Lake Park covers a total area of 560 mu, with a water area of 186 mu. Curved, arched, and flat bridges are laid out in an interlaced manner, and pavilions, halls, and terraces complement each other. The path on the shore leads to a secluded place, with weeping willows and winding paths around; the reeds in the lake are swaying, duckweed is exposed, and boats are rowing, creating a Jiangnan scenery.
