After Cao Cao broke through Yecheng, Xu You relied on his high merits and repeatedly belittled Cao Cao, and every time he attended, regardless of the occasion, he called Cao Cao by his nickname and said: "Apu, without me, you can't get Jizhou." Cao Cao smiled on the surface and said, "You're right. "But I have a lot of guilt. Once, Xu Yu went out of the east gate of Yecheng and said to the left and right: "This family can't enter this gate without me." Someone reported it to Cao Cao, so Xu Yu was taken into custody and eventually killed.

Xu You is also a more controversial figure in history, many people are very shameful about his betrayal, and even think that Yuan Shao can win the battle of Guandu without Xu You's reason, and some people think that Xu You Huaicai is not met, and Yuan Shao's failure to use his own strategists is self-inflicted.

So what kind of person is Xu You? What level of ability is he?

[Unconvincing proposal]

Xu You has been following Yuan Shao after Yuan Shao left Luoyang, and was an early strategist who took refuge in Yuan Shao, and in the later stage of the decisive battle of Guandu, Xu You proposed to Yuan Shao to divide his troops and send troops to attack Xuchang, but Yuan Shao refused, so he held a grudge.

Now many people think that Xu You's proposal is very reasonable and can be regarded as a breakthrough point to break the deadlock, while Yuan Shao is dazed and incompetent and can't follow the advice, but in fact, Xu You's proposal to divide the troops at that time was not very convincing, and Yuan Shao did not adopt it for a reason.

First of all, Yuan Shao had already done it in the early stage of Guandu, but the effect was very poor, Liu Bei and Han Xun he sent had failed, and at that time, Liu Bei led the headquarters of the troops and horses in the area of Yuzhou, and also defeated Cai Yang, the general sent by Cao Cao, but it did not form much of a storm.

Moreover, Guandu is quite far from Xuchang, Cao Cao was ready to withdraw from Guandu, lure Yuan Shao to go deep and then defeat it, which at least shows that Cao Cao may have prepared more than one defensive line in Guandu, so Yuan Shao sent fewer troops, and the limit of what can basically be done is Liu Bei's, and it is impossible to pose any decent threat to Xuchang.

And if Yuan Shao sent too many troops, it would be basically impossible for the supplies to keep up, and Yuan Shao faced Cao Cao directly, relying on the superiority of troops to suppress it, and sending out soldiers, he would not be able to suppress Cao Cao.

In the end, Yuan Shao didn't need to divide his troops at that time, the situation at that time was already very unfavorable for Cao Cao, Cao Cao couldn't afford a long-term tug-of-war, so as long as Yuan Shao dragged Cao Cao back, he could drag Cao Cao to death, and dividing his troops would add to it.

【Reason for Betrayal】

And Xu You's history was not because Yuan Shao did not listen to his advice to betray Yuan Shao and join Cao Cao, but because his family was interrogated, I am afraid that he was afraid of Yuan Shao's investigation and turned his back.

After Xu You's proposal was vetoed by Yuan Shao, although Xu You was angry, he had no intention of leaving Yuan Shao, and then Xu You was tried and sent to prison directly because of the greed for money and crime in Yecheng's family.

At that time, Xu You's misconduct was not a secret news, Xun Yu once commented that Xu You was "greedy but not cured", and in "Three Kingdoms: Emperor Wu Ji", Xu You was also described as greedy for money, and it reached the point that Yuan Shao was no longer satisfied. These all show that Xu Yu was not a good thing when he was on Yuan Shao's side.

【The turning point of Guandu】

In history, Xu Yu betrayed Yuan Shao and took refuge in Cao Cao, and offered the strategy of attacking Wuchao, which was the turning point of the decisive battle of Guandu, which has very far-reaching significance. Therefore, many people think that without Xu You, the Guandu War is very likely to change, but in fact, Xu You's proposal cannot be said to be very powerful, and the success is mainly due to Yuan Shao's incompetence.

First of all, before Cao Cao attacked Wuchao, something similar had already happened, at Xun You's suggestion, Cao Cao had sent Xu Huang and others to attack Yuan Shao's supply team, and it was a great success, that is to say, Yuan Shao had already suffered a loss, but he obviously failed to take it as a warning.

Secondly, Fu Zhi had warned Yuan Shao earlier that Cao Cao might attack the convoy, and suggested that more generals be sent as guards, but Yuan Shao just didn't listen.

In the end, Zhang He and others saw that Wuchao was attacked, and persuaded Yuan Shao to rescue him, but Yuan Shao sent the army to fight Cao Cao's camp, and only sent a light army to rescue.

And even if Xu You didn't take refuge in Cao Cao, Cao Cao might have attacked Chun Yuqiong, at that time Cao Cao wanted to settle the battle as soon as possible, and had been waiting for the opportunity, and attacking Yuan Shao's grain transport team was definitely a good opportunity, not to mention that Cao Cao and others had already done this once, and they had gained a lot, so Cao Cao had every reason to do it a second time.

Even if Cao Cao didn't expect it, Xun You would most likely mention it.

Of course, none of these can erase the "merits" that Xu You made in this battle, but it is important to understand that Yuan Shao's defeat was not only because of a fire in Wuchao, but because Yan Liang and Wen Chou died in battle, and Liu Bei and Han Xun, who divided their troops, failed, and Yuan Shao himself couldn't defeat Cao Cao's camp, which was accumulated from a series of defeats, and Xu You's matter was just the last straw that crushed the camel's camel, even if there was no Xu You's matter, there were others who would put it on it.

Xu You's betrayal and scheming were one of the direct reasons for Yuan Shao's defeat, but not the root cause. Xu You's betrayal did have a negative impact on Yuan Shao's group, but compared to Yuan Shao, it can only be a small thing, even if in addition to Yuan Shao, there are many guys who have a worse influence than Xu You.

【Limited Talent】

Xu You is not a very talented guy in history, he has also participated in some major events, first Jizhou assassin Wang Fen and others conspired to abolish the establishment, and even once won over Cao Cao, but failed to do anything, after the incident was exposed, Wang Fen committed suicide, Xu You fled.

Then Xu You took refuge in Yuan Shao, and followed Yuan Shao for a long time, in addition to being considered "greedy but not cured" by Xun Yu before the decisive battle of Guandu, he was basically invisible. In the late stage of the decisive battle of Guandu, Xu You finally spoke, and repeated the old tune of suggesting that Yuan Shao divide his troops to attack Xuchang, but his proposal was basically unconvincing, very general, and of little value.

However, the brilliance of Xu You's life was because he was investigated for corruption, so he betrayed his boss Yuan Shao, and surrendered to the enemy, which eventually led to the defeat of the old master.

Corruption and betrayal seem to be stains, and there is nothing to be proud of. But what about Xu Yu? After Yuan Shao's death, he revisited Yecheng, and proudly told others that it was thanks to him Cao Cao that he was able to conquer Yecheng, for fear that others would not know that he was a heartless person who betrayed the master.

However, the timing of Xu You's election was not very good, Cao Cao had already defeated Yuan Shao at that time, and he was the actual first person in the world at that time, and he no longer needed to pay as much attention as he did when dealing with Youheng, so Boss Cao felt that Xu You would go directly to prison after making himself unhappy, and a guy like Xu You who was arrogant and didn't have much talent naturally couldn't get the sympathy and help of others, so Xu You was killed.

It's very much in line with the fate of a traitor.
