CGTN's filming crew has managed to get a peek at the diversified marine lives roaming in the depth of the waters atoll of the Xisha Islands in the South China Sea, Sansha City in southern China's Hainan Province. The vibrant colors and stunning shapes of the species against the blue seawater have just brought us into a quiet and peaceful world we rarely see. China has been strengthening environmental protection in Sansha City, which was established in 2012, to administer islets and reefs in Xisha, Zhongsha and Nansha islet groups as well as waters in the area.
