Introduction to Laihe Island: Laihe Island is located in a retention dam built in the early days of Tianjiagou. After years of treatment, the silt has flattened the gullies in the dam. In summer and autumn, reeds are swaying here, blue waves are rippling, and teal ducks and wild cranes are seen here. Rare birds such as ducks and mandarin ducks were playing among them, and the desolation of the past was completely different from the barren mountains and rivers, so it was named "Laihe Island".
