Since it is located on the south coast of Liji Town, Wanning City, it is connected to Shimei Bay. Because this is the place where the bird's nest bird and the spring swallow live in the cold, it gets its name. It is also said that the seaside cliff here is shaped like a giant swallow floating in the water, so it gets its name. Nanyan Bay is rich in tourism resources, with towering peaks and cliffs, clear springs and waterfalls, huge caves, white beaches, green trees and green trees, blue sky and blue sea, and abundant aquatic products. In addition, there is an 18-hole golf course invested and constructed by Japanese companies.
