It wasn't Lu Bu who attacked Yanzhou back then, and Liu Bei and Tao Qian estimated that it would be over sooner or later. After Lu Bu took back Xuzhou, he didn't touch a single hair of Liu Bei's family, not only sent it back to Liu Bei's family intact, but also gave Xiaopei to Liu Bei.
Yuan Gate shot a halberd, Liu Bei was besieged by Yuan Shu, Lu Bu sent troops to rescue him as soon as possible, and saved Liu Bei's life at the risk of offending Yuan Shu. Why did Liu Bei want to take revenge and unite with Cao Cao to get him? This Liu Bei is too uninteresting.
Lu Bu took back Xuzhou and did not move Liu Bei's family to set aside Xiaopei for Liu Bei to station, Lu Bu was captured, Liu Bei should have helped Lu Bu intercede, but Liu Bei not only did not help to intercede, but also fanned the flames and let Cao Cao be Lu Bu's father-in-law. caused Cao Cao to be furious and ordered Lu Bu to be executed?
Liu Bei should be regarded as Cao Cao accepted Lu Bu, so that it will be much easier for Liu Bei to beat Cao Cao later, and persuading Cao Cao to kill Lu Bu will make it difficult for Liu Bei to defeat Cao Cao, and it can be seen from Huarong Dao that if Lu Bu accompanies Cao Cao to escape, he will definitely repay his kindness when he meets Liu Bei
