The origin of Tujia nationality?

There are different opinions about the origin of Tujia nationality. One is that Tujia people are descendants of Ba people. One is that some barbarians moved from Guizhou to Xiangxi in ancient times; Even the descendants of white craftsmen who moved from Jiangxi to Xiangxi at the end of the Tang Dynasty and the beginning of the Five Dynasties (about 9 10), some people think that they are descendants of Han border guards and indigenous women. According to Fudan University's spot check on Tujia paternal genes, Altai is the most paternal lineage of Tujia, accounting for about 28% (roughly Xiongnu and Xianbei). Followed by Baiyue 25%; Tibet, Japan and Myanmar are the main sources of Tujia language and culture, ranking third among the three sources, accounting for 2 1% (Qiang); In addition, there are 14% Han people, 7% Miao people and 5% Indo-European people (it should be the intermediary and Yue people in Wuhu). According to historical records (Tujia only appeared in historical records at the end of the Tang Dynasty), linguistic research (Altai component in Tujia language), paternal genetic results and Tujia epic records, it can be roughly known that Tujia was formed after the integration of Wuhu and Baiyue ethnic groups, and a mixed-race ethnic group with both Altai and Baiyue cultural components was basically formed at the end of the Tang Dynasty. Nevertheless, Tujia nationality is still a Tibetan-Burmese nationality, and Tibetan-Burmese culture is the core of Biji culture, and it lives in harmony with He, Myanmar (Burmese), Tibetan, Yi, Manipur, Karen, Rakhine, Jingpo (Kachin), Bai, Hani, Lisu, Yi, Naxi and Qiang.
