The Dalajiao Island is located in Daya Bay, separated from the Aotou Port by a water. The beach stretches on the island, and colorful shells are scattered among them. There are so many snails, small conch, and scallops. If you pick up the shell along the beach, the experience is very good. The Dalajiao Island was once a military site. After it was changed to civilian use, it became a salt fish acquisition and processing base under the Huiyang Fisheries Bureau. Later, the tourism department opened the Dalajiao Island as a tourist attraction.
