The image of Cao Cao in Romance of the Three Kingdoms is defined as a traitor in troubled times. His mouth is very fierce, which is reflected in the banquet before Wang Yun assassinated Dong Zhuo. Cao Cao is a very talented strategist and accomplished in literary creation. Most of his poems show his heroic temperament and ambition. In the romance of the Three Kingdoms, Cao Cao is a veritable big mouth. His big mouth reflects his frivolous spirit, which is beyond our literal understanding. He likes to talk about others behind their backs. From observing the sea, we can realize that its mouth is very big. The old horse crouches, aiming at a thousand miles, and the martyrs are full of courage in their twilight years. ? Cao Cao's sentence means that although I am old, my ambition is higher than the sky and thicker than the earth. This poem not only shows his frivolous spirit, but also leaps his ambition into the hearts of the world. Among the Three Kingdoms, Cao Cao is a worthy opponent. He is a tough guy in troubled times. This tough guy didn't mean to derogate, but actually praised him, indicating that this man is smart and brave. And he knows how to make good use of people. As long as he is a talented person, no matter which school you go to, he will choose to appreciate it. Cao Cao's eloquence is probably the reason for his big mouth. In history, Cao Cao also said that having children should be like Sun Zhongmou, which is also the embodiment of his frivolous mouth. As the master of Wu Dong, Sun Quan is very capable. He has strong leadership skills, and he also has talents like Zhou Yu. Sun Quan showed extraordinary temperament at an early age. When he was a child, he used to be an emissary, sending Liu Biao, which directly shocked Liu Biao. Its initial effect is far stronger than that of old messengers with many experiences. Therefore, this sentence of Cao Cao is really frivolous, and it also reflects his big mouth.
