You might say that Liu Bei threw a bucket, but Liu Bei threw it into the crowd. He did it only to buy people's hearts. Speaking of Liu Bei, let's look at Cao Cao again. The book says that Cao Cao is ugly and short. On one occasion, the Xiongnu emissary came to visit, and Cao Cao knew that the Xiongnu said it was a visit, but it was actually a visit. If he thinks the big fellow is not bad, he will attack on a large scale. Cao Cao looked in the mirror and felt ugly, so he found a counselor to replace him and be his own guard. After the meeting, Cao Cao still didn't trust to send someone to ask. The spies came back and told Cao Cao that the emissary said that the master of Wei was handsome, but the guards around him were brave.
