僰人 Bo people
僰人の子孫はラチ（Lachi, 拉基族）とク（Ku, 谷族）。ラチはタイ・カダイ系、クはロロ・ビルマ系。クは「吊るされた棺」の風習を保存し、今もBoとして知られる。「吊るされた棺」の被葬者のミトコンドリアDNAハプログループは意外なことに北方系のG3a1cで共通している。
Possible descendants
1. Lachi
The Lachi people of Vietnam and China may be descended from the Bo, based on the archaic exonym Labo (喇僰) in Chinese records.[10] The Lachi language belongs to the Kra subgroup of the Kra-Dai language family. Today, the Lachi refer to themselves as qu31 te341, with qu31 meaning 'people' (from Proto-Kra *khraC1 'people').[10]
2. Ku
The Ku of Qiubei County currently speak a Loloish language, and still practice hanging coffin traditions. According to their own records, the Ku people's ancestors had migrated from Yibin, Sichuan province a few centuries ago in order to escape wars.
Varieties
There are three different varieties of Ku.[2] Speakers of each consider themselves to be separate ethnic groups.[1] However, they are officially classified by the Chinese government as ethnic Yi.[3]
Ku (autonym: ku55) is spoken in Bainitang 白泥塘,[4] Shede Township 舍得彝族乡, Qiubei County, Yunnan Province. They are also locally known as the Bo (Chinese: 僰人; pinyin: Bó rén), and continue to build hanging coffins. The
Ku of Bainitang claim that their ancestors had migrated from Yibin, Sichuan.
Another variety of Ku (autonym: ku55) in Wujiazhai 五家寨,[5] Shede Township 舍得彝族乡, Qiubei County, Yunnan Province is unintelligible with Ku of Bainitang 白泥塘.
