The Yongle Islands are an island group in the western part of the Xisha Islands in China. Located about 40 nautical miles southwest of Yongxing Island, they are also known as the western island group and the western eight islands. They are mainly composed of Ganquan Island, Coral Island, Senping Shoal, Jinqing Island, Chenhang Island, Guangjin Island, Jin Yin Island, Zhongjian Island, Huaguang Reef, Panshi Yu, North Reef and other islands, reefs and shoals. The first six are all on the same huge arc-shaped reef flat, known as Yongle Atoll. There are 13 large and small islands on Yongle Atoll. Outside Yongle Atoll, there are two more islands: Zhongjian Island is an island with a relatively large land area in the Yongle Islands and is located at the western end of the Xisha Islands; the island on Panshi Yu Atoll is Panshi Yu. Each island is surrounded by sandbanks. The middle is low and flat. There are freshwater wells. Some are sweet and drinkable, and some can be used but not drinkable. There are trees such as Tournefortia argentea, Casuarina equisetifolia, and coconut trees. There are many passages between the islands and reefs of the Yongle Islands leading to the sea, such as Laocumen, Quanfumen, Yinyumen, Shiyumen, Jinqingmen, Ganquanmen, etc. There are also many reefs such as Lingyang Reef. Therefore, the Yongle Islands are an atoll with more islands among the South China Sea Islands and also the main island group of the Xisha Islands.
