Xun Yu assisted Cao Cao all his life, why did he oppose Cao Cao in the end?

Because of Cao Cao, he completely overthrew the world of the Han Dynasty and established a new dynasty, which made him go against his original intention.

Because Cao Cao wanted to be the emperor at that time, tampering with the Han dynasty, to put it bluntly, he was going to rebel, so he would oppose him.

In fact, he did not oppose Cao Cao, he did it for Cao Cao's good, he didn't want Cao Cao to be emperor too early and make people despise him.

Because Xun Yu was loyal to the Han family and paid attention to honor, Cao Cao's approach later made him disagree, so he had to oppose Cao Cao.

Xun Yu and Cao Cao had a difference in thought, he wanted to restore the Han Dynasty, he didn't want Cao Cao to be the emperor, he felt that Cao Cao's approach to becoming the emperor was very unsafe.

The main thing is that he is very principled, and if this matter touches his bottom line, then he will choose the better side.

Because he didn't want Cao Cao to become a thief who rebelled against the country, the reason why he supported Cao Cao at the beginning was because Cao Cao had been supporting the Han family, but he didn't expect Cao Cao to have wolf ambitions and want to ascend the throne as emperor.

This is because Xun Yu has his own interests and needs, and he knows that it is particularly dangerous to do things by Cao Cao's side, and he is like a tiger, so he chose to oppose Cao Cao in the end.

Because he was a person who defended the Han family, Cao Cao wanted to be emperor, which was not quite in line with his original idea, so he would oppose Cao Cao.

On the issue of whether Cao Cao entered the country and added nine tins, Xun Yu and Cao Cao had a contradiction. This is the collision between Xun Yu's ideals and Cao Cao's ambitions, and it also represents Xun Yu's insistence on his own ethics. Xun Yu was finally deprived of all power by Cao Cao and died under house arrest in the army.

The reason why Xun Yu voted for the Cao family is because in that special troubled era, the Han royal family is weak and unable to save the people from fire and water, which requires a strong man with great talent to maintain social order, therefore, he can only choose Cao Cao as the realizer of his value goals, and his behavior is loyal to the Cao family on the surface, but his heart is actually for "Han Zuo", which can be described as well-intentioned.

Later, Cao Cao's ambitions increased step by step with the expansion of his power, and Cao Cao's heart appeared with the idea of replacing the Han family. Xun Yu, as Cao Cao's closest and most powerful assistant, Xun Yu immediately sensed Cao Cao's heart. This is unacceptable to Xun Yu, and it is natural to oppose it.

Xun Yu formulated a blueprint and military line for Cao Cao's plan to unify the north in terms of strategy, and was praised by Cao Cao for revising his strategic policy many times, including "deeply rooted in the foundation to control the world" and "welcoming the Son of Heaven"; Tactically, in the face of Lu Bu's rebellion and the preservation of the three cities of Yanzhou, he plotted to contain Yuan Shao in Guandu, and made many achievements such as Wan and Ye making light advances to cover his surprise attack on Jingzhou.

Politically, a large number of talents such as Zhong Xuan, Xun You, Chen Qun, Du Xi, Xi Zhicai, and Guo Jia were recommended for Cao Cao. Xun Yu has made many achievements in planning, conspiracy, Kuang Bi, and raising people, and was called "my son's room" by Cao Cao.
