Qing'ao Bay is a bay on the east side of Nanao Island. The azure waters and smooth sand make it the most beautiful bay in Nanao Island. The mouth of the bay opens towards the southeast, and the bay itself is very deep. Looking down from above, the bay looks like a giant crescent with the rows of casuarina trees spread along the solitary beach. The waves, white sand, forest belts and new buildings in the forest form a beautiful view of the beach.
