History is an objective fact and there is only one truth. However, the knowledge of recording and studying history often changes, develops and perfects with people's subjective consciousness, and even distorts and fabricates it.

We should look at right and wrong in history from a rational point of view. For thousands of years, China's view of history has always been a winner and a loser. History is always written by winners. No matter what he did before the victory, as long as he finally won the victory, everything he did was right, and what he represented was always just. And the loser, no matter what good or beneficial things he has done before. In the eyes of the winner, everything is for himself, and the loser always represents the unjust side. It is precisely because of this narrow and extreme view of history that we cannot correctly look at the true side of many people and things in history. No matter who or what, it is true and credible that people will put a coffin on him only after he has finished his work or died for several years. The quality of a person or a thing should be proved by practice, and practice is the only criterion for testing truth. This is definitely not your true evaluation with your mouth or books.
