To the northwest of Pingtan Island and along the more than 500-meter sea surface in the west of Kan'ao Village stands a disc-shaped reef, which holds two tablet-shaped rocks. The combination of these rocks is like a big ship with two sails, riding on the crest of waves. This is the most famous natural scenic spot in Pingtan -- Shipaiyang, also known as the "Double-Sail Rock". Photo provided to China Daily
