In the Romance of the Three Kingdoms, we know that Cao Cao was an ancient adulterer, very selfish and cruel, and suspicious. In the fourth episode, Cao Cao said to Chen Gong: "Ning taught me to bear the people of the world, and Hugh taught the people of the world to bear me." After Cao Cao's failed assassination of Dong Zhuo, he was wanted by the whole country, and in desperation, he fled the capital and passed through Mu County on the way to escape, and the soldiers guarding the pass captured Cao Cao and sent him to Chen Gong. Chen Gong admired Cao Cao very much after hearing about him, and when he saw such a loyal person, he admired him and expressed his willingness to follow Cao Gong, Cao Cao was very happy after listening to it, and that night, Chen Gong and Cao Cao packed up and left Mu County.
On the way, Cao Cao arrived at the home of his uncle Lü Bohao, who had planned to spend the night and continue the road the next day. Lü Bohao was very happy that his virtuous nephew could visit, and ordered his family to kill pigs for hospitality, while he went to the town to buy wine. However, Cao Cao was suspicious, and after hearing the sound of sharpening knives outside, he thought that Lü Bohao wanted to kill himself, so he killed Lü Bohao's family by mistake. Later, Cao Cao discovered that the people of Lü Bohao's family were only to kill pigs to entertain Cao Cao, and he killed Lü Bohao's family by mistake, so he left in a hurry. On the way, when he met Lü Bohao buying wine and returning, Cao Cao was very worried that Lü Bohao would accuse himself, so he swung his sword and hacked his uncle Lü Bohao to death. Chen Gong saw this scene and regretted following Cao Cao very much, and thought that Cao Cao was a villain, but Cao Cao replied: "Ning taught me to bear the people of the world, and Hugh taught the people of the world to bear me", and finally Chen Gong left him.
In fact, in the Three Kingdoms, everyone has their own personality, and Cao Cao's personality is named Han Xiang, who is actually a Han thief, a traitor in a chaotic world, no different from Dong Zhuo, but the real history is not like this. In fact, Cao Cao was forced to kill Lü Bohao's family, but to highlight the image that Cao Cao was a traitor, it can only be said that Cao Cao killed Lü Bohao's family unjustly.
In the canonical history, Cao Cao came to Lü Bohao's house to spend the night, when Lü Bohao went to the town to buy wine, and Lü Bohao's family was very enthusiastic about Cao Cao, which made Cao Cao suspicious. In fact, at that time, Lü Bohao's subordinates were very covetous of the horses and finances of Cao Cao and his party, because Cao Cao and others were wanted criminals, and even if they robbed their property, they did not dare to report to the officials, so they prepared to attack. However, Cao Cao heard the sound of sharpening his knife outside and thought that someone was going to kill him, so he first killed Lü Bohao's family.
In this way, Cao Cao killed Lü Bohao's family and beat him up, which was not unjust at all, but Cao Cao and Lü Bohao were only friends, and after Cao Cao succeeded, he built a better mausoleum for Lü Bohao.
