Then the most important thing is to look at the original historical materials rather than the second creation.

First of all, we must understand the basic tools of historical research.

Including basic reference books.

School classification of historical research and so on.

Then read the original.

China, that is, history books, etc.

The second book can only be used as a reference.

You can't treat it as raw material.

Those things in the Ming dynasty and so on can be seen as jokes.

It's basically unbelievable.
