Introduction to the waterfowl pond: The waterfowl pond is located in the southeast of Yinchu Lake, covering an area of ​​2,000 square meters. It was originally planned to raise ornamental waterfowl, but was not implemented later. There are two small islands in the pool. Because of the peonies and azaleas planted on the islands, they were once called Peony Island and Azalea Island. On the east bank of the pool is a hexagonal bamboo pavilion, named Tianqu Pavilion, with an area of ​​9 square meters.
