Cao Cao is a very complicated man. Sometimes he is open-minded, sometimes petty, sometimes gentle and tolerant, and sometimes murderous and ruthless. He has the tender side of a man, and he also likes to flirt with women outside. It is difficult to sum up him in one sentence or one word. Comparing the historical Cao Cao with the Romance of the Three Kingdoms, first of all, he is not as cunning as shown in the Romance of the Three Kingdoms. The Romance of the Three Kingdoms praises Liu and suppresses Cao. Cao Cao likes to use tactics. When he writes about the Romance of the Three Kingdoms, it makes people feel that it is all a conspiracy. . Cao Cao wrote an article "The Turtle Sushou", which contains these two sentences: The old man is in trouble, and his ambition is thousands of miles. In his old age, the martyr is full of ambition. The poem is very talented and ambitious. From the poem, we can feel that he is not a completely treacherous person as written in the Romance of the Three Kingdoms.
