The sand in Sanyang is black, which makes the sea water near to be dark and has a special flavor. The sea water in the distance is still blue and the scenery is different from usual. There are many beautiful shells and conches on the seashore. There are many different kinds of living shells lying on the rocks, but they can't be pulled out. They are so powerful. Friends who want to collect shells can go here. The last one is the black sand in the conch.
