Introduction to Yaodao: At the western end of Yintan Tourist Resort, there is a small island in the sea one kilometer away from the shore, which is called Yaodao. Whenever the tide rises and falls, Yaodao is like a green boat, floating and wandering in the waves, sinking and floating. When tourists look at it, it looks like a flat boat. Whenever the tide is still, Yaodao looks like a dazzling green gem set in the sea.
