Xu Yu made great contributions to Cao Cao in the Battle of Guandu, why did Cao Cao execute him as so

Because Xu You's mouth was open, he always felt that he had made great contributions, often disrespectful to Cao Cao, and talked nonsense, so he was later executed.

First, because after Xu You helped Cao Cao, he drank and had fun every day, and called Cao Cao to call Cao Apu in public, which was very disrespectful to Cao Cao. Second, because Cao Cao was suspicious by nature, Cao Cao felt that Xu You could betray Yuan Shao and betray him, so he executed Xu You.

Because Xu You was disrespectful, he kept calling Cao Cao's name and was very disrespectful to him, so Cao Cao naturally would not let him go.

1.Cao Cao thought that Xu You was a restless person and was afraid that it would be difficult to control. As early as 184 A.D., Xu Yu united with Jizhou Assassin Wang Fen, Peiguo Zhou Jing and others to plot to abolish Emperor Ling of the Han Dynasty and re-establish the Marquis of Hefei as the emperor.

Xu You also persuaded Cao Cao to participate together, but Cao Cao refused.

3.Second, Cao Cao couldn't bear Xu You's arrogance. Xu You decided that most of Cao Cao's elite troops were on the front line of Guandu, and Xuchang in the rear was empty, and suggested that Yuan Shao send an elite army to attack Xuchang.

It is a pity that this reasonable suggestion did not have Yuan Shao's consent. Soon, Xu You's family broke the law and was arrested by the interrogator who stayed in Yecheng, and Xu You was frightened when he knew about it, so he defected to Cao Cao.

Because Xu Yu insulted Cao Cao many times; Xu You was a little arrogant and excessive, he didn't take Cao Cao in his eyes at all, and disrespected Cao Cao many times, which was dissatisfied with Cao Cao.

Because Xu You is a two-faced person, if you don't kill him, maybe one day you will defect to the enemy.

Because Cao Cao was a suspicious person, he felt that Xu You would usurp the throne through such a Fang Qingshu style, so he would kill the other party. Cao Cao felt that he was highly meritorious, that he was too capable, that his ability had surpassed his own, that he would threaten his position, and that he would kill the other party.

Because he was proud of his achievements, he tried to put forward some conditions to Cao Cao that could not be met, and Cao Cao was very cautious, he thought that Xu You's request threatened to fight him, so he killed him with the silver book; The tour includes Cao Cao's personal political stupidity and power schemes, and Xu Yu is excessively conceited and does not recognize the reality.

Because he knew Cao Cao too well and knew a lot of things about Cao Cao, and secondly, he was also relieved because he had already made a high achievement, which had affected Cao Cao's status, and it was also to be able to warn others, so he would kill Qiao Cover.

The main reason is that Lu Yu is a loss because Xu You knows Cao Cao very well, and he also knows a lot of things about Cao Cao's early empty operation, and secondly, because he has threatened Cao Cao's position, and it is also to give others a warning, so he will be killed.
