What are the Greek islands in Sansha City, Hainan Province?

There are cliffs and canyons The waters around Xisha Islands are colorful and magnificent: dark blue, light blue, light green and apricot yellow. Fragments, strips, intertwined. Because the seabed is uneven, there are cliffs and canyons, and the sea water is deep and shallow. Seen from the sea, the color is different. There are all kinds of corals on the rocks at the bottom of the sea, some like blooming flowers and some like forked antlers. Sea cucumbers are everywhere, lazily crawling on the seabed.
