and the person's own name (ex. Aho Bbujji Jjiha Lomusse). Aho is the name of a tribe, Bbuji is the name of a clan, Jjiha is the father's name, and Lomusse is a personal name. The name therefore means Lomusse the son of Jjiha of the Bbujji clan of the Aho tribe. Within the clan he would just be called Lomusse and within the tribe he would be called Jjiha Lomusse. This system can also be seen in the names of Nanzhao's rulers: Xinuluo Luosheng Shengluopi Piluoge Geluofeng Fengjiayi Yimouxun Xungequan Quanfengyou – sought to imitate Chinese practices and only went by Fengyou; broke tradition and named his son Shilong Shilong Longshun Shunhuazhen This is a tradition closely tied to Tibeto-Burman traditions and suggests that the rulers of Nanzhao were not Tai people. Culture Gender Descent and inheritance in Yi society was traditionally patrilineal and men were generally considered superior to women. Men practiced polygamy and levirate marriage. Women were excluded from oral genealogies. In certain locales, Yi women still lag behind men in terms of primary education and very few Yi women become educational instructors or political leaders. Yi women noticeably drank and smoked more than Han Chinese women. Slavery Traditional Yi society was divided into four castes, the aristocratic nuohuo/nzymo Black Yi, the commoner qunuo/quho White Yi, the ajia/mgajie, and the xiaxi/gaxy. The Black Yi made up around 7 per cent of the population while the White Yi made up 50 per cent of the population. The two castes did not intermarry and the Black Yi were always considered of higher status than the White Yi, even if the White Yi was wealthier or owned more slaves. The White and Black Yi also lived in separate villages. The Black Yi did not farm, which was traditionally done by White Yi and slaves. Black Yi were responsible only for administration and military activities. The White Yi were not technically slaves but lived as indentured servants to the Black Yi. The Ajia made up 33 per cent of the population. They were owned by both the Black and White Yi and worked as indentured laborers lower than the White Yi. The Xiaxi were the lowest caste. They were slaves who lived with their owners' livestock and had no rights. They could be beaten, sold, and killed for sport. Membership of all four castes was through patrilineal descent.
