The Jiyang Lake Ecological Park is located in the south of Zhangjiagang City, very close to the city center. The water area of the center of Jiyang Lake is vast. It is an artificial lake excavated by means of concentrated soil borrowing. This not only saves the cultivated land along the line, but also protects the surrounding environment. It also expands the scale of the city, improves the living environment, and inherits the ancient cum. Yanghu culture played an important role.
