Bo people
The language of the Bo people of Gong County, Sichuan is unknown, but I suspect it may have been a Kra language. The Bo (Ku) of Bainitang, Qiubei County today speak a Northern Loloish language.
Pig:
'pig 猪': máng máng 牤牤 or alternatively niōng niōng (Huang & Li 2006:25)
Jianshan m̥uŋ⁴²
Vandu (Vietnam) m̥oŋ⁵⁵
Xinfa ɑ³³ȵuŋ⁵³
Bigong ŋo³¹
Only Red Gelao dialects have a final nasal. Xinfa Red Gelao, which is similar to Hongfeng Red Gelao, has a form (ɑ³³ȵuŋ⁵³) similar to the residual Bo form.
Cai-Long languages have *li. The Tibeto-Burman form *pwak is unrelated.

'meat 肉': gà gà 尬尬 (Huang & Li 2006:25)
