There is a legend about Treasure Island: a big pirate named Wu Ping in the Ming Dynasty, active in Fujian and Guangdong coasts all year round, looted a lot of gold and silver treasures, and the property was rich and enemy country. After Qi Jiguang swept Pingxuan, Wu Ping was chased to Treasure Island, put gold and silver in 18 large cans, hidden in 18 places on the island, here became a veritable "Treasure Island". However, the specific hiding place of this treasure is unknown so far, even if there is a cracking folk song: I go north and south, east and west hide the crust. The water can't flood, the water can't flood three feet.
