Cao Cao passed by Lu Boshe's house on his way back to his hometown from Dong Zhuo. He killed Lu Boshe's family because he suspected that they were going to plot against him. Luo Guanzhong of the Ming Dynasty processed this period of history in the historical novel "The Romance of the Three Kingdoms", and it also became the source of Cao Cao's famous saying in the novel, "I would rather teach me to betray the people of the world than teach the people of the world to betray me."

"Book of Wei" says that Lü Boxe was an old friend of Cao Cao. When Cao Cao fled from Dong Zhuo, he and several people rode to find Lü Boxe. Lü Boxe happened to be away, so Lü Boxe's son and guests arrived. The enemy attempted to rob Cao Cao and his party, but Cao Cao counterattacked and killed several of them. This is considered self-defense and there is nothing unkind. Extended information
