Introduction to Yuanyang Lake: Yuanyang Lake in Pigeon Nest Park was originally a tidal flat with low-lying terrain and was abandoned all year round. Later, due to the construction of sea dams, a small, calm lake was formed and named Yuanyang Lake. There is a small island in the lake called Lover's Island. The island is lush with trees and full of romance. Every summer, many young men and women in love go on dates here.
