2. In the first year of Xingping (194), Cao Cao led an army to pacify Tao and stayed in the East County for garrison, but he conspired with Juck Zhang, the satrap of Zhang Miao and the brother of Zhang Miao, to lead Lu Bu into Yanzhou. For a time, several county chiefs in Yanzhou responded to the uprising, leaving only Juancheng. He once defeated Cao Cao several times, but was finally defeated by Cao Jun's clever use of strategy and tactics, and was forced to flee to Xuzhou with Lu Bu to take refuge in Liu Bei.
3. Cao took it away and finally came to a small county. He was recognized by some jailers, arrested and told Chen Gong, the local county magistrate, that Chen Gong was a man who respected loyal officials very much. He knew that Cao Cao had assassinated Dong Zhuo, who killed all the people in the world, and got into trouble, so he didn't want to hand him over for a reward. He went to visit Cao Cao in prison. As a result, Cao Cao's words influenced him. He felt that Cao Cao was one of the few loyal ministers in the world.
4. On the way to escape from Chang 'an with Cao Cao, Cao Cao killed his father's sworn brother, Lv Boshe's family, and said, "I'd rather teach me to fail the world than the world to fail me." In that case. Chen Gong thought Cao Cao was a narrow-minded adulterer, so he abandoned him and turned to Lu Bu.
5. After Cao Cao came to power, he attacked Yanzhou gentry and killed Yanzhou celebrities Bian Rang and others. Bian Jean is a good friend of Chen Gong and an important figure among Yanzhou gentry. Cao Cao's behavior aroused the dissatisfaction of the whole Yanzhou cremation. Chen Gong, as the leader of Yanzhou cremation, naturally won't let Cao Cao go. Yanzhou cremation united against Cao Cao, welcomed Lu Bu into Yanzhou, and almost destroyed Cao Cao, so Chen Gong and Cao Cao forged a great hatred.
