The Lachi people of Vietnam and China may be descended from the Bo, based on the archaic exonym Labo (喇僰) in Chinese records. 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').
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.
There are three different varieties of Ku. Speakers of each consider themselves to be separate ethnic groups. However, they are officially classified by the Chinese government as ethnic Yi.
Ku (autonym: ku55) is spoken in Bainitang 白泥塘, 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, Shede Township 舍得彝族乡, Qiubei County, Yunnan Province is unintelligible with Ku of Bainitang 白泥塘.
