Did Bo people really become extinct in the Ming Dynasty?

Not extinct, found many people.

Experts discovered the descendants of the Gelao nationality in Xingwen County, Yibin City, Sichuan Province in 2005. The estimated total may exceed 1 ten thousand. It was the Xingwen CPPCC that tapped historical resources and invited some experts in literature and history to make a field trip to Luobiao, Jiu Si, Lingxiao and Gongxian. Experts found in the investigation that there are still quite a few descendants of Gelao nationality living in Xingwen County. Xingwen county is one of the main settlements of Bo people, and is known as the "hometown of burning people".

The above situation has been officially reported.
