Introduction to Jiulong Spring: The entire terrain here slopes from west to east. There is an open space of about 2660 square meters in the low-lying area at the east end. There are several clear springs in it, arranged at a certain distance, each with a clear pool. Each pool is connected by small ditches, and at the end there is a small canal that leads the overflowing spring water to the willow forest on the bank of the Tuman River in the east, forming a complete spring scene.
