To speak of Cao Cao, there are literary talents and strategies, needless to say, he is a tyrant in a chaotic world. But it is such a tyrant who seems to have a different hobby from others, that is, to like other people's wives. When Cao Cao defeated Lü Bu, Lü Bu's Qin Yilu also surrendered to Cao Cao. Qin Yilu was a general under Lü Bu, and originally had a beautiful wife, Lady Du, but because Yuan Shu admired her very much, he gave his daughter Xu to Qin Yilu, and he stayed with Yuan Shu, while his wife Lady Du stayed in Xia Pi.
When Cao Cao and Liu Bei besieged Lü Bu, Guan Yu once proposed to Cao Cao that he give him Qin Yilu's wife Lady Du after the siege. But the fact is that Cao Cao himself married Lady Du, and abnormally, Guan Yu was uneasy, why was this? Guan Yu actually mentioned Lady Du to Cao Cao many times, saying that it was normal once, but it was difficult for others to pay attention to it. Cao Cao became curious about Lady Du, what kind of beautiful woman this was, so that Guan Yu could not forget it, and as a result, it was indeed a beautiful woman in the world.
Why didn't Cao Cao give Lady Du to Guan Yu and just do it as a human kindness? It should be known that at the time of the Battle of Xia Pi, Cao Cao wanted to absorb Liu Bei and Guan Yu. The absence of Guan Yu's wish just reflected Cao Cao's strategy. Guan Yu always made this request to Cao Cao, and it was reasonable to say that if he wanted to achieve his goal, it would not be better to let Liu Bei come to him and say that it was not better, but Liu Bei did not mention it to Cao Cao. This aroused Cao Cao's curiosity, and he felt that Liu Bei might not know about it. If Liu Bei didn't know it beforehand and gave Lady Du to Guan Yu, wouldn't it seem that he had ulterior motives, so Cao Cao didn't do it.
Guan Yu was uneasy when he saw things turn out like this, not because he was afraid that Liu Bei would think that he wanted to defect to Cao Cao, but because he was afraid that Cao Cao would take this opportunity to get rid of Liu Bei. Guan Yu was robbed of his wife, and there must have been a great resentment in his heart, and he once wanted to assassinate Cao Cao. Guan Yu was afraid that after Cao Cao knew his thoughts, he would put the blame on Liu Bei's body and get rid of Liu Bei. It is not difficult for Cao Cao to see that Liu Bei is not willing to be subordinated, as a talent, of course, if he does not get it, he will get a bad end, so it is very normal for Guan Yu to have such concerns.
Liu Bei is not an idle person, he is very ambitious. After the destruction of the city, he rebelled in Xuzhou the following year, but was soon pacified by Cao Cao. At that time, after Cao Cao included Lady Du in his harem, he also had a son in vain, named Qin Lang. After entering the palace, he gave birth to two sons and a daughter for Cao Cao, which is also considered a consummation.
