Personality: "I would rather be negative than negative". It can be seen from this sentence of Cao Cao that he is an extreme egoist. Of course, it is not surprising that he has such a character in the war-torn era, but how many people can really be negative? In fact, Bian Xiao thinks that Cao Cao is more real than Liu Bei's "benevolence" and Sun Quan's "forbearance".
He is very talented and has many shortcomings. He never hides them. No matter what future generations say, he dares to act boldly, understand the situation and know the people's hearts. A "hold the emperor to make the princes" accounts for "human harmony". He is not Dong Zhuo. Dong Zhuo also praised the emperor, but he didn't have Cao Cao's ambition. He called himself the emperor's father, which made everyone angry.
For example, Yu Xun and Guo Jia came to Cao Cao from Yuan Shao when Cao Cao didn't have much strength. It can be seen that he has a strong personality charm in addition to being thirsty for talents. I think it is more appropriate to evaluate Cao Cao with "a minister who has the ability to manage the world and a treacherous man in troubled times".
