The small house that is faintly visible on the sea is the life-saving tower on Taigong Island. When the tide is low, Taigong Island will reveal the sea. It is a very magical island formed by reefs in the sea. When I came to low tide last year, I climbed up and was very fun. Taigong Island in the evening was not completely submerged by the tide, and the life-saving towers on the island were clearly visible, except for nothing, only bare reefs, which were motionless in the sea.
