Wanji Swimming Pool: Intersection of Station Road and Changqing Street,

Rainbow swimming pool: intersection of Furong Street and Jiaotong Road,

Hawaiian Swimming Pool: Shang Zhou Road goes south.

There is also a sluice, which is a clear river upstream. Most people go in summer, and spontaneously it becomes a crowded natural open-air swimming pool.
