Hou Cheng retrieved fifteen warhorses, carrying a jar of wine to prepare to celebrate with Song Xian and Wei Xu, the wine jar had not yet opened Lü Bu came over, Lü Bu thought of taking advantage of this opportunity to establish military prestige, opened his mouth and said that Hou Cheng violated the prohibition of alcohol, according to military regulations, Song Xian and Wei Xu quickly knelt down to plead, Lü Bu changed his mouth to beat fifty military sticks.

Sun Wu beheaded King Wu's concubine when he was training troops, and the world praised Sun Wu for being good at governing the army, and Lü Bu beat Hou Cheng into a military stick according to military regulations. The same is strict military law, but Lü Bu and Sun Wuzhen can not speak the same day, because the situation of the two is completely different, Lü Bu himself is addicted to drinking, delayed a lot of fighters, his subordinates did not make a mistake because of drinking, Lü Bu suddenly issued a prohibition order is unreasonable.
Lü Bu and these three subordinates did not know each other for a day or two, but the three of them did not admire Lü Bu, and their service to Lü Bu was very much like mixing bowls of rice, far from the step of "the soldier died for the confidant", which laid a hidden danger for Lü Bu to be captured alive and sacrificed to Cao Cao. Lü Bu relied on the Red Rabbit Horse, which was stolen by Hou Cheng, and later tied up by Song Xian and Wei Xu wuhua, and was given to Cao Cao as a "meeting gift", and Cao Cao of course laughed.
Cao Cao "got" Lü Bu and had to consider how to deal with it, Lü Bu tried to impress Cao Cao with his bravery and invincibility, Cao Cao hesitated at that time, so he asked Liu Bei what he thought, Liu Bei mentioned Ding Yuan and Dong Zhuo, at this time Cao Cao ordered Lü Bu to be shown to the public. There was a doubt in this process, how could Cao Cao not know how to deal with Lü Bu? Cao Cao's advantage is that he knows people well, whether Lü Bu can use it, and how to use it, Cao Cao already knows in his heart, even if Cao Cao really can't make up his mind for a while, he doesn't need to ask Liu Bei's opinion, because he has Guo Jia and Xun Yu, which wisdom will not be worse than Liu Bei, and Cao Cao and Liu Bei are not familiar with each other, nor have they established a relationship of trust.
<h1 class="pgc-h-arrow-right" > so why would Cao Cao ask Liu Bei? </h1>
This has to start from why Liu Bei defected to Cao Cao, Liu Bei originally had his own city of Xuzhou, when Liu Bei went south to Huainan to confront Yuan Shu, Lü Bu secretly attacked Xuzhou to succeed, Liu Bei could only settle down in Xiao Pei, and then Lü Bu secretly attacked Xiao Pei, this time Liu Bei was really cornered, had to defect to Cao Cao, it can be said that the reason why Liu Bei sent people here in Cao Cao was all because of Lü Bu, can he not hate Lü Bu?
So Cao Cao probably knew what Liu Bei had in dealing with Lü Bu, but what Cao Cao wanted to know was what Liu Bei would say, and Liu Bei did not grit his teeth and say how Capricious Lü Bu was, but gave an example of the fate of Ding Yuan and Dong Zhuo, and told Cao Cao lü Bu disloyalty with facts. Cao Cao asked very cleverly, Liu Bei replied just right, the evaluation of Lü Bu was in line with the facts and did not directly indicate his attitude, as to how to deal with it or leave it to Cao Cao to decide. If Liu Bei said good things for Lü Bu, it was likely to make Cao Cao suspicious; if Liu Bei said what to do with Lü Bu, this would be tantamount to making decisions for Cao Cao, and it would also cause Cao Cao to be unhappy.
After this, there was the matter of "Qingmei boiling wine on heroes", Cao Cao had a high evaluation of Liu Bei, believing that the heroes of the world could only be counted as himself and Liu Bei, of course, this was not directly related to the words Liu Bei said in the White Gate Tower, but at that time Cao Cao should have thought that Liu Bei was unfathomable!
