Booi Aha
Booi Aha (Manchu: ᠪᠣᠣᡳ ᠨᡳᠶᠠᠯᠮᠠ (booi niyalma) for male, ᠪᠣᠣᡳ ᡥᡝᡥᡝ (booi hehe) for female; Chinese transliteration: 包衣阿哈) is a Manchu word literally meaning "household person", referring to hereditarily servile people in the Eight Banner system in 17th-century Qing China. It is often directly translated as "bondservant", although sometimes also simply rendered as the common word, slave, or more specifically within Chinese social and political context as nucai.
