Triton Island

Zhongjian Island is located at the southern end of the Xisha Islands in Sansha City, Hainan Province, China. It is 50 kilometers southwest of Huaguang Reef in the northeast, 90 kilometers away from Jinqing Island, the main island of Yongle, and 178 kilometers away from Yongxing Island, the main island of Xisha. Chinese fishermen are commonly known as Luodao or Banluzhi, and it is now called the Zhongjian warship in memory of 1946. Some say it belongs to the Yongle Islands, and some say it belongs to the isolated islands of Xisha. With an altitude of more than 2 meters, the land area has been reduced from 1.5 square kilometers to 1.2 square kilometers due to wind and waves. High tides of typhoons often flood most of the island. At high tide, Zhongjian Island is only the size of two football fields, or 0.014 square kilometers, about one percent of that at low tide. The reef is large, about 7.5 square kilometers. The island is a gray-sand island developed on the top of the reef, surrounded by sand embankments, and there are residual shallow lagoons inside.
