Officially, Cao Cao is indeed a national hero, bustling and peaceful. However, when he is in a high position, his political opponents will naturally attack him; From his death to the Song Dynasty, Cao Cao began to be portrayed as a villain because of the political requirements at that time. In the Ming dynasty, through the collection of novelists' folk stories, an image of a traitor in a formal suit finally appeared, which was passed down from generation to generation.
Putting this sentence in a TV series is a counterattack against the "world" attack in the TV series. If you jump out of the TV series, the meaning will be more obvious. This is the name of Cao Cao in the New Three Kingdoms: since the birth of Cao Cao's novel image, the world has subconsciously combined Cao Cao in reality with Cao Cao in the novel, and the voice of criticism is endless; But no matter what later generations say, Cao Cao is so real and powerful in history, his mistakes are not covered up by criticism, and his achievements are not obliterated by criticism. Heroes are heroes, and Cao Cao is Cao Cao.
