Xu You was greedy for money and betrayed to offer money to the enemy, which has had a very bad impact on Yuan Shao's group, and is even considered by many people to be the culprit of Yuan Shao's failure, but it also depends on who you compare it with, if you compare Xu You with Guo Tu, in a sense, what Xu You does is not a problem.

【Hindering the Emperor】

Guo Tu is a native of Yingchuan, and Xun Yu, Guo Jia and others are fellow countrymen, and he followed Yuan Shao very early, and was one of the first few strategists to follow Yuan Shao. Later, he was sent by Yuan Shao to meet Jizhou Mu Hanfu with Xin Ping, Xun Chen and others, and persuaded him to give up Jizhou.

And this incident is also the only thing in the history of Guo Tu that has a positive impact on Yuan Shao Group. Then Guo Tu's actions pushed the Yuan Group step by step to a desperate situation of failure and even destruction.

In the second year of Xingping (195), Emperor Xian was exiled in Hedong, at this time he persuaded Yuan Shao to welcome the Son of Heaven, and Guo Tu and Chun Yuqiong made a hindrance, they thought that the revival of the Han family was hopeless, and the Son of Heaven was a burden to Yuan Shao, obeying the Son of Heaven would be restricted, and disobedience would be considered disobedience to the emperor's orders.

As a result, Yuan Shao missed this opportunity, and the Son of Heaven was taken away by Cao Cao, and then Cao Cao coerced the Son of Heaven and ordered Yuan Shao to make Yuan Shao half angry. Although it is also recorded in the "Chronicles of the Three Kingdoms" that Guo Tu advised Yuan Shao to welcome the Son of Heaven, the overall possibility is not very high.

And Guo Tu may have been affected by this incident, but Guo Tu had his own way, and soon coaxed Yuan Shao to be happy, and since then he has gone to the road of development and has risen step by step within Yuan Shao Group.

[Sycophant upper position]

Guo Tu's method of ascending to the throne is very simple, that is, obey Yuan Shao's will, Yuan Shao to the east, Guo Tu will never go west, he patted Yuan Shao's sycophants, hugged Yuan Shao's thighs, and finally succeeded in squeezing out the frustration, but also led Yuan Shao to the abyss of failure.

In the fourth year of Jian'an (199), Yuan Shao eliminated Gongsun Zan and basically unified the north, so Yuan Shao prepared a large army to go south to crusade against Cao Cao and take away Emperor Xian. At this time, Fu Zhu advocated a delay in the war and spent more time dragging Cao Cao to death.

When Guo Tu saw this situation, he followed Yuan Shao's intentions and thought that Yuan Shao's soldiers should be sent to eliminate Cao Cao immediately, but Fu Zhu retorted that the danger was too high, Guo Tu didn't think about it, but said that Fu Zhu was too safe.

After Yuan Shao adopted Guo Tu's opinion, Guo Tu took the opportunity to make a small report on the frustrated delegation, which led to the division of most of the frustrated power. Then he was not ready to cross the Yellow River, which offended Yuan Shao, and Yuan Shao gave all the power to Guo Tu, and Guo Tu's status reached its peak at this time.

But the high status does not mean that you can do things.

Then in the decisive battle of Guandu, Wuchao was attacked by Cao Cao, Zhang He and other generals persuaded Yuan Shao to immediately send a large army to rescue, Guo Tu saw that Yuan Shao intended to attack Cao Cao's camp, so he persuaded heavy troops to attack Cao Cao's camp, resulting in the lack of rescue troops in Wuchao, failed to repel Cao Cao, the supplies were all destroyed by Cao Cao, and many generals under Yuan Shao's command were killed.

This is not the most cheating, after Guo Tu saw this result, because of his weak heart, he framed Zhang He and other generals to Yuan Shao, which directly led to the rebellion of Zhang He and others.

[Lead civil strife, lure foreign enemies]

After Yuan Shao's death, Guo Tu took refuge in Yuan Tan and began his new "glory".

First of all, Guo Tu and Xin Ping sowed discord, causing Yuan Tan and Yuan Shang brothers to break up and attack each other. Later, Guo Tu offered Yuan Tan a plan to lure Cao Cao and destroy Yuan Shang, and directly gave Cao Cao a reason and excuse to go north, so that he could easily defeat Yuan Shang and conquer Yecheng.

According to Guo Tu's plan, Yuan Tan took advantage of Cao Cao's crusade against Yuan Shang, betrayed Cao Cao, seized territory, and tried in vain to unify the north, but how could Yuan Tan be Cao Cao's opponent, Yuan Tan and Guo Tu were also killed after the city was broken.

【The Worst Strategist】

Guo Tu is the worst strategist in the Three Kingdoms era who can be evaluated as -S in the true sense! The failure of Yuan Shao and the fall of the Yuan Group Guo Tu are quite a credit!

In history, although Xu Yu was the master of the pit, in the final analysis, he also offered Cao Cao a strategy to attack the black nest, but what about Guo Tu?

He first prevented Yuan Shao from welcoming the Son of Heaven, and at that time, he stirred up this matter when Yuan Shao had already said that he was moved, and as a result, a year later, Cao Cao took Emperor Xian away, and his momentum increased greatly, and his power developed rapidly, from Yuan Shao's younger brother to a big man, which directly threatened Yuan Shao's status. If Yuan Shao gets the Son of Heaven in his hands, according to Yuan Shao's strength at that time, even if he can't sweep the world by taking a step back, he will definitely have more than enough self-preservation.

At that time, although Cao Cao was strong, he did not have the righteousness of the Son of Heaven, Cao Cao had been a pastor of Yanzhou for four or five years, and the development of his power was not fast, and the threat to Yuan Shao after that could be said to be relatively limited.

Before the decisive battle of Guandu, Guo Tu obeyed Yuan Shao's intention to lead the army to crusade against Cao Cao and fight a decisive battle with him, and gave up the strategy of frustration and prudence, and the result was the fiasco of the Battle of Guandu, with 70,000 or 80,000 people under Yuan Shao's army killed and many generals killed. Since then, the strength of Yuan Shao's group has been greatly damaged, and it has begun to go downhill, and was finally eliminated by Cao Cao.

And in the performance of the Battle of Wuchao, what Guo Tu did was actually worse than Xu You. Guo Tu first advocated a heavy attack on Cao Cao's camp, and the consequences directly made the rescue of Guandu's troops insufficient, resulting in the failure of the Wuchao defense battle.

In fact, after the defeat of Wuchao, Yuan Shao still had a fight, after all, Yuan Shao still occupied the military advantage, and it was difficult for Cao Cao to swallow Yuan Shao's so many troops in one gulp, but then Guo Tu came again, he framed Zhang He, who was leading a heavy army at that time, and made Zhang He defect, which was too deadly.

Zhang He surrendered with the army and gave Yuan Shao the final blow, and Yuan Shao really couldn't hold on. Therefore, Xu You's rebellion and dedication plan is one of the direct reasons for the failure of Yuan Shao's Guandu, and it can only be one of them, Guo Tu's foolishness, Yuan Shao's incompetence, Zhang He's rebellion at the critical moment and even Cao Jun's outstanding performance are all factors that cannot be ignored at that time, and they are even more critical than Xu You.

However, Guo Tu's scourge of the Yuan family did not stop there, after Yuan Shao's death, Yuan Tan and Yuan Shang's brothers had a share of the infighting, but what was even worse was that Guo Tu proposed that Yuan Tan take refuge in Cao Cao and lure the wolf into the house.

At that time, Cao Cao was originally going to fight Liu Biao at the suggestion of Guo Jia, and he had temporarily let go of the Yuan brothers, and then Guo Tu asked Yuan Tan to send Xin Bi to Cao Cao, and as a result, Cao Cao's belief in the Northern Expedition was strengthened, and Cao Cao was brought back.

From another point of view, Guo Tu first asked Yuan Shao to give up welcoming the Son of Heaven, and then successfully squeezed out the most powerful frustration in Yuan Shao's group, and then in the Battle of Wuchao, he even advocated weakening to support Chun Yuqiong's forces, minimizing the pressure on Cao Cao, and then letting Zhang He and others surrender to the battlefield. After Yuan Shao's death, he induced the Yuan brothers to fight among themselves, so that Yuan Tan surrendered first and then rebelled, helping Cao Cao to get the north more easily.

In a sense, Guo Tu was Cao Cao's biggest "hero" who was able to win the emperor, defeat Yuan Shao, and unify the north.
