Introduction to theme activities: Every year, theme activities such as "I'm a Mud Maniac" and "Mud Sliding Season" are held here. Students from colleges and universities inside and outside the island, overseas guests, and fishermen and farmers form teams to participate. A series of activities allow people to get close to the sea mud, feel the good ecological environment of Xiushan Island and the unique health and beauty effects of sea mud, and fully enjoy the health and happiness that sea mud gives us.
