Nanyue, or Nam Việt in Vietnamese was an ancient kingdom founded by the Chinese general Zhao Tuo, whose family continued to rule until 111 BC. Nanyue's geographical expanse covered the modern Chinese subdivisions of Guangdong, Guangxi, Hainan, Hong Kong, Macau, southern Fujian and central to northern Vietnam. Zhao Tuo, then Commander of Nanhai Commandery of the Qin dynasty, established Nanyue in 204 BC after the collapse of the Qin dynasty. At first, it consisted of the commanderies of Nanhai, Guilin, and Xiang.
