The mountains on the island have been hollowed out, leaving more than 1360 caves and caves. These caves are all dug down from the upper opening, so the shape of the hill remains intact. The pirate village scenic spot is a scenic spot built on the basis of the pirate base. The caves left by these quarries are very hidden and safe. The great pirate king of the Ming Dynasty once squatted on the island of Snake Island as a camp. The quarry in ancient times was very difficult and dangerous.
