Bo

The Bo were an ancient people of the mountain borderlands of southern Sichuan and Yunnan, remembered for their hanging coffins; Chinese records class them with the Di and Qiang. In the Zhou dynasty they were known as the Pu, a Hundred Pu tribe of the upper Yangtze, and when Qin conquered Ba in 316 BC their lands passed to Qin.

Their language is thought to have belonged to the Kra group, and the cliff faces of their old country still hold coffins hollowed from single logs with bronze drums.

The Bo fortress of Lingxiao on Bowang Mountain in Xingwen was the last Song redoubt against the Mongols, holding out until 1288, more than eleven years after the Song fell. In 1573 Ming armies besieged Lingxiao and Gong County; the Bo were killed or absorbed and vanished from the written record.
