Chinese term for various foreigners living outside the borders of Ancient China
"Four Barbarians" (Chinese: 四夷; pinyin: sìyí) was a term used by subjects of the Zhou and Han dynasties to refer to the four major people groups living outside the borders of Huaxia. Each was named for a cardinal direction: the Dongyi ("Eastern Barbarians"), Nanman ("Southern Barbarians"), Xirong ("Western Barbarians"), and Beidi ("Northern Barbarians"). Ultimately, the four barbarian groups either emigrated away from the Chinese heartland or were partly assimilated through sinicization into Chinese culture during later dynasties. After this early period, "barbarians" to the north and the west would often be designated as "Hu" (胡).
