Someone asked: If Sun Quan had not killed Guan Yu, but had sent Guan Yu alive to Cao Cao, what would Cao Cao have done?

I believe that this question is a difficult question for cao cao and for us to make up. Because Cao Cao really liked Guan Yu, and Guan Yu's threat to Cao Cao was really big, the flooded Seventh Army threatened Huaxia not to say, the white horse siege force beheaded Yan Liang was also a technical pressure, and Cao Cao's feelings for Guan Yu were both love and hate.
The reason why Sun Quan gave Guan Yu's head to Cao Cao was actually to divert the contradiction and try to spread Liu Bei's hatred for himself to the two people. But Cao Cao was not a fool, and naturally could see through Sun Quan's tricks, so he not only asked people to carve a fragrant wood body, but also brought hundreds of officials to bury Guan Yu with the courtesy of princes.
When Sun Quan saw it, he did not dare to resist the thunder alone, and quickly buried Guan Yu's torso with the courtesy of the princes.
In this way, Guan Yu's head was buried in Luoyang, his torso was buried in Dangyang, and his crown was buried in Chengdu.
"Rest your head on Luoyang, lie down in the sun, and return to your hometown."
Later, Liu Bei did spill his resentment on Sun Quan, and his practical toes were also thought of, and there was a master of unjust debts, and Guan Yu's lost Jingzhou was occupied by Eastern Wu, of course, looking for Sun Quan to settle accounts. Sun Quan was also unambiguous, "pounced" on Cao Pi's knees and declared himself a vassal, thus avoiding a two-end battle.
Back to the question, if Sun Quan had not killed Guan Yu, but had given the living to Cao Cao, what would Cao Cao have done?
In fact, in front of Cao Cao, there are only four choices:
The first was to release Guan Yu and let him return to Liu Bei; the second was to simply kill Guan Yu to alleviate the threat he was facing; the third was not to let go and not kill good food and drink, and waited for him, and put under house arrest; the fourth, how to send it back, kicked the ball to Sun Quan.
Looking at the first option first, there are many people who think that Cao Cao will release Guan Yu and let Guan Yu go back to involve the energy of Eastern Wu and reap the benefits of the fisherman himself, I personally think it cannot. Because Cao Cao had received Guan Yu once before, because of His Talent, he would rather let him go than kill him, but Cao Cao paid a great price for it.
In 219 AD, Guan Yu launched the Battle of Xiangfan, yu Ban Pound and other Cao Wei generals came to support, but guan Yu defeated, beheaded Pound, captured alive in Ban, and severely damaged Cao Wei. And Cao Cao had just touched a nose of ash in Hanzhong, if it were not for Sun Quan's sneak attack on Jingzhou, I really don't know if Cao Cao would become the second Yuan Shao. Cao Cao had suffered such a big loss, how could he still send Guan Yu's bomb back to Liu Bei, Boss Cao weighed the pros and cons and should not fall twice in the same pit.
If Cao Cao had put Guan Yu back and Guan Yu had not died, Liu Bei might not have had red eyes with Sun Quan, plus Zhuge Liang had tried his best to unite with the Shu state of Wu to unite against Cao. Guan Yu was frustrated and lost Jingzhou, and may be replaced by Liu Bei, in case the Shu state does not fight with the State of Wu under reason, then Cao Cao will not make any money, so I think Cao Cao will not let Guan Yu go back.
Then the second possibility, killing Guan Yu, I think is too impossible!
Because Cao Cao may have been subjected to wild retaliation from Liu Bei, especially liu Bei's battle of Hanzhong had just been won, and morale was high. The red-eyed Liu Bei may have directly responded to Zhuge Liang's call, and the shame of Jingzhou would be counted after the autumn and united against Cao Cao. Liu Bei was directly allin, and Cao Cao really had the possibility of not being able to resist.
For Sun Quan, Liu Bei was very happy to see Cao Cao in order to avenge himself, and it would not be unpleasant to cooperate with Liu Bei in battle to divide Cao Wei and make steady profits. In addition, Cao Cao also likes Guan Yu, so I think Cao Cao will not kill Guan Yu directly, although Guan Yu is a great threat to himself, Sun Quan kicked the ball to him, Cao Cao will definitely analyze the stakes.
So is it possible to put Guan Yu under house arrest in the third way?
If Cao Cao left Guan Yu behind, eating and drinking well, the only purpose should be to see if he could grind it and let Guan Yu surrender for my use. But Guan Erye Yi Bo Yuntian is famous, Taoyuan Sanjieyi one head hit the ground, if Cao Cao could win over, he succeeded a few years ago, so Cao Cao should not make any more investment.
However, Cao Cao took Guan Yu in his hand as a weight to negotiate with Liu Bei, and perhaps this was a good choice. Asking the State of Shu to cooperate with him in annihilating the State of Wu and then Guan Yu returning you, plus the State of Wu capturing Jingzhou, Liu Bei may have really agreed to Cao Cao's request. If Cao Wei and Shu Han jointly divided Jiangdong equally, the strongest and weakest forces divided the medium forces equally, and it was Cao Cao who benefited the most. But this is a dangerous move, there is a risk of playing smashing, in case Guan Yu in order not to give Liu Bei a hindrance to commit suicide and martyrdom, that is worse than Cao Cao personally killed Guan Yu, it will make Liu Bei uncomfortable, the battle of Wei Shu is inevitable.
So in the end, I still think that Cao Cao will send Guan Yu back untouched, whether Guan Yu dies or lives, that is something that Sun Quan has to consider. Kill Guan Yu Liu Bei and play with your life, do not kill Guan Yu, in case Liu Bei comes back to take your Jingzhou is also troublesome. Shu Han's thunder let Sun Quan go to the point, cao Cao watched the fire from the other side of the shore how not to hurt his own vitality, and even to take advantage of it.
Cao Cao can make the best choice, but he is bitter second master, of course, he released the bold words "Tiger girl can marry a dog", and he did not expect that he had become a tiger in a cage, and let people send it as a gift.
?
I think that if that were the case, Guan Yu might not wait until Cao Cao sent someone else, and he would have committed suicide...
