In my opinion, the so-called "historical facts" we see now are just an imperfect appearance, just as Plato put forward in the Republic that reality is an ideal mirror image, but it is not perfect. It is impossible for us to obtain complete historical facts. Because it is always lost, and many historical materials are second-hand, they have been processed by other historians or parties. I agree with Edward? Carl's point of view, historical facts are important materials, and the key to the problem lies in how to explain historical facts. Different people will have different opinions from different angles, but the most important thing is to be based on facts, even if the facts are not perfect. We should abandon personal prejudice (such as class and country) as much as possible when dealing with historical facts, but it does not mean engaging in national nihilism and historical nihilism. No matter how you think about it, you must have your own national and ethnic norms (you can't blindly attack some historical facts because of the interests of the country and the nation, you must be brave enough to admit your mistakes and look at the problem dialectically). It's best to study Ma Zhe's historical materialism, which is of great help for you to correctly understand historical facts.
