Harbor introduction: The two ridges are connected by a narrow white beach about 800 meters long and 40 meters wide, forming two harbors, commonly known as "front harbor" and "back harbor". The front port is a natural bathing beach, and the back port can accommodate large ships. When the tide is high, the beach is submerged by the sea water, and the two ridges are naturally separated. When the tide is low, the two ridges merge into one island, showing the magic of the island's natural landscape day after day.
