Introduction to cliff carvings: The two cliff carvings of "Wudang Scenic Spot" and "Wanhai Pingbo" were carved during the Jiaqing period of the Qing Dynasty. At that time, the great pirate Zhang Baozai commanded the "Five Color Gang" troops of 40,000 people and 4 large ships, and dominated the South China Sea under the banner of "anti-Qing and destroying foreign countries" and "robbing the rich and giving to the poor". In the first year of Jiaqing, they took Lantau Island as their nest, went in and out of the Pearl River Estuary, and carved the words "Ten Thousand Seas Ping Bo" and "God's Palace" on Dong'ao Island. Twenty years after Jiaqing, they were conquered by the Qing army and evacuated Dong'ao Island. It is said that before leaving, they buried 18 boxes of treasures near the stone carvings and divided them into "eighteen rows of treasures and eighteen rows of treasures". Will return later. Where the treasure is hidden has always been a mystery.
