Sansha - Prefecture-level city in Hainan, People's Republic of China

"Sansha City is a prefecture-level city under the Hainan province of the People's Republic of China (PRC), and is the southernmost and least populated prefecture in China, with the smallest land area but the largest maritime territory. The city's seat is located on Yongxing Island in the South China Sea, and administers several island groups, atolls, seamounts and a number of other ungrouped maritime features within the nine-dash line, although the PRC's de facto control over the area varies. The name "Sansha", literally meaning "three sands", refers to the three archipelago districts of Xisha, Zhongsha and Nansha. - Wikipedia"
