BC, Zhao Tuo persuaded Minyue, Yelang, Tongshi, and other areas to submit to Nanyue rule, but they were not strictly under Nanyue control. After the Western Han dynasty defeated Nanyue, its territory was divided into the seven commanderies of Nanhai, Cangwu, Yulin, Hepu, Jiaozhi, Jiuzhen, and Rinan. It was traditionally believed that the Qin conquest of the southern regions included the northern half of Vietnam, and that this area was also under Nanyue control. However, scholars have recently stated that the Qin likely never conquered territory in what is now Vietnam, and that Chinese domination there was first accomplished by the Nanyue themselves. Administrative Divisions Zhao Tuo followed the Commandery-County system of the Qin dynasty when organizing the Kingdom of Nanyue. He left Nanhai Commandery and Guilin Commandery intact, then divided Xiang Commandery into the Jiaozhi and Jiuzhen Commanderies. Nanhai comprised most of modern Guangdong Province, and was divided by the Qin into Panyu, Longchuan, Boluo, and Jieyang Counties, to which Zhao Tuo added Zhenyang and Hankuang. Ethnicities The majority of Nanyue's residents probably consisted of mainly Yue peoples. The Han Chinese population consisted of descendants of Qin armies sent to conquer the south, as well as girls who worked as army prostitutes, exiled Qin officials, exiled criminals, merchants and so on. The Yue people were divided into numerous branches, tribes, and clans. The Nanyue lived in north, east, and central Guangdong, as well as a small group in east Guangxi. The Xi'ou lived in most of Guangxi and western Guangdong, with most of the population concentrated along the Xun River region and areas south of the Gui River, both part of the Xi River watershed. Descendants of Yi-Xu-Song, the chieftain killed resisting the Qin armies, acted as self-imposed governors of the Xi'ou clans. At the time of Nanyue's defeat by the Han dynasty, there were several hundred thousand Xi'ou people in Guilin Commandery alone. The Luoyue clans lived in what is now western and southern Guangxi, northern Vietnam, the Leizhou Peninsula, Hainan, and southwest Guizhou. Populations were centered in the Zuo and You watersheds in Guangxi, the Red River Delta in northern Vietnam, and the Pan River watershed in Guizhou. The Chinese name "Luo", which denoted a white horse with a black mane, is said to have been applied to them after the Chinese saw their slash-and-burn method of hillside cultivation.
