Introduction to Yandu Reed Marsh: Located on the southern shore of Nanhai Lake, there is a vast wetland system, which is a precious ecological resource and landscape resource in the South China Sea. Groups of wild geese return every spring, so there are several buildings in the scenic area. The set of wooden rafts guides tourists into the depths of the wetland, which not only satisfies people's desire to explore the wetland, but also effectively protects the wetland resources.
