In which specific area are Xiliang, Xiliao, Nanliang and Beiliang in history? Do they have descendants? What nationality are they?

Xiliang, Xiliao, Nanliang and Beiliang are all in the northwest of China!

All of them have descendants, that is, ethnic minorities with Chinese characteristics have become members of the Han nationality, saying that it is either you or their descendants!

The demise of the nation is not that everyone is dead, but that the living habits of future generations have changed. Without the living habits of their ancestors, they don't know who their ancestors are. Generally, they have become Han Chinese.

For example, the ancestors of most people in Kunming, Yunnan are descendants of Kunming, an extinct minority in Yunnan.

There were Han immigrants from the Central Plains in ancient Kunming. These people are a minority, and most local ethnic minorities have studied China culture for a long time. Their descendants have the same living habits as the Han people. They all say that their ancestors came from the Central Plains and he is a Han nationality. There are few actual immigrants, and the Han nationality in China is formed by the integration of numerous ancient ethnic minorities.
