This question: First of all, 1, China people believe in ancestors, so the records of ancestors are very strict.

There were not many famous people in ancient times, not to mention their surnames. (Non-nationals are called foreigners or freemen, and when nationals are not in their own country, they are called savages, which also refers to the countryside. People in our country are called China people, and people in China are nobles with surnames. )

Even if Xiang Yu burned so many documents, folk rumors are particularly important, just like a constantly changing book.
