I Tried to Persuade Cao Cao for 20 Years, but He Didn't Listen to a Word

At the end of the Eastern Han Dynasty, when Chen Gong, the magistrate of Zhongmou County, was escorting the fugitive Cao Cao, he was moved by his enthusiasm to help the Han Dynasty and abandoned his official position. That night, Cao Cao killed eight members of his old friend Lu Boshe's family out of suspicion. He wiped his sword and said, "I would rather teach me to betray the world." Chen Gong was shocked, but did not leave - he said to himself: I want to change him.
