We can make a scenario to simulate the situation at that time. Then you'll find a lot of interesting things. At that time, Cao Cao's order of persuasion was Gao Shun - Chen Gong - Lü Bu - Zhang Liao. Then we get into the situation.
Cao Cao besieged the city for two months, that is, he could not defeat the city of Pi, besieged the city for two months, the loss of soldiers, grain and grass were a large number, Cao Cao was not too rich at that time, and the siege of the city for these two months was also a kind of suffering for him. It was hard to kill into the city of Xia Pi and capture Lü Bu and his party alive, what did Cao Cao need? It was someone else who praised Cao Cheng xiang's wisdom and divine martial arts, and then Cao Cao himself waved a big hand, and all the generals under Lü Bu surrendered, and then the Banshi returned to the dynasty, and reported to the Emperor of Han, and then the story of Cao Cao's capture of Lü Bu was spread all over the world. Therefore, Cao Cao now belongs to the time when the momentum is at its highest, and it is also the time when he is most proud.

Cao Cao then began to summon the first man, Gao Shun. As a result, Gao Shun was stubborn and stubborn, and in the face of Cao Cao's surrender, he did not say a word. This kind of person is like a stone, you can't do anything with him. Therefore, Cao Cao's arrogance was directly extinguished by Gao Shun's basin of cold water. I guess Gao Shun should have a face that didn't answer and was indifferent at this time. When Cao Cao saw Gao Shun's appearance, he was directly furious and directly killed Gao Shun to vent his anger. Moreover, Gao Shun did not have any acquaintances in the Cao camp, and each of them interceded for him, and poor Gao Shun died tragically.
Then the second person, the old friend Chen Gong, was summoned. In the face of his old friend Chen Gong, Cao Cao's psychology should be full of regret. He regretted what he had done at that time and forced Chen Gong away, and hated Chen Gong for helping Lü Bu not help himself. After Chen Gong told Cao Cao about the aftermath, Cao Cao decided to help Chen Gong take care of his family, and finally executed Chen Gong. After Chen Gong persuaded him to surrender, Cao Cao's psychology should be in a complex mood of regret, discomfort, and sadness.
Then summon a third man, the old rival Lü Bu. Facing this former world's first martial artist, his old rival Lü Bu. Looking at the ugly appearance of him being pressed to the ground and begging for forgiveness, Cao Cao's psychology must have been very proud, "Your boy also has today." Then Cao Cao, a person with a very serious suspicious heart disease, decided that Cao Cao would not surrender Lü Bu, Cao Cao ostensibly asked Liu Bei if he wanted Lü Bu, but in fact he waited for Liu Bei to say no, and then pushed this pot on Liu Bei. Liu Bei sent people to the fence, and naturally could only cooperate with Cao Cao's performance. In this way, Lü Bu died, and then he was still calling Liu Bei a "big ear thief". At this time, Cao Cao killed his confidant Lü Bu and also played Liu Bei for a while, and Cao Cao's psychology should be very cool.
Then there was the fourth person, Zhang Liao. Zhang Liao scolded At Cao Cao, to tell the truth, I am not afraid of you cursing people, I am afraid that you will not say a word like Gao Shun. But Cao Cao was still a little upset, so he took the sword and wanted to cut Zhang Liao. As a result, he was stopped by Guan Yu, and it happened that Cao Cao was in a good mood at this time, so he did not continue to pursue Zhang Liao. Instead, he took off his clothes and draped them on Zhang Liao's body, and let him sit on the seat, and in this way, Zhang Liao was touched by Cao Cao and surrendered.
The order of this surrender is also learned. Although we all say that people who have become big things are moody and angry, after all, they still have some feelings in their psychology!
