The most shameless example of Cao Cao is that after killing Lu Boshe's family, knowing that it was a manslaughter and not regretting at all, he could still say in front of Chen Gong, "I would rather bear the consequences of the world." Teach the people of the world to bear me down." But although this sentence was very shameless, it highlighted the cruelty and blackness of Cao Cao's heart. Cao Cao cannot be called thick-skinned, but rather ruthless and vicious. His level of thick-skinned is completely different from that of Liu Bei.

Liu Bei relied entirely on his thick skin to survive. Since he started his army, Liu Bei has relied on Tao Qian, Lu Bu, Cao Cao, Yuan Shao, and Liu Biao to eat and drink shamelessly. Liu Bei's tears should be the most valuable in history. He can cry to Jingzhou and build his morale. How precious these tears are. But Liu Bei cries anyway. He can always seize the weakest point in human nature and start crying bitterly. This shows that he is good at observing human nature and can be regarded as a master in recognizing people. He knows what kind of people cry has an effect on and when. Effect, crying can get twice the result with half the effort. Take crying and Liu Bei's eating and drinking as an example. You can know that Liu Bei's face is dozens of times thicker than Cao Cao's, but his heart is not as dark as Cao Cao's.

It’s no wonder that when Qingmei was making wine, a person with the thickest skin in the world at that time, and a person with the darkest heart in the world at that time, met each other. You can’t do anything to me, and I can’t do anything to you. Looking around the world at that time Among the princes, such as Yuan Shao, Liu Zhang, Liu Biao and others, who can be the opponent of these two people? That's why Cao Cao said while making green plum wine: "The only heroes in the world are your envoy and Cao Er.
