What influence did the battle of Guandu have on the direction of the three countries? What is the main impact?

Regarding the role of the battle of Guandu, I personally feel that it is a fatal blow to Yuan Shao, and Yuan Shao's power has never recovered. Once again, it originated from Yuan Shao's previous decision to make Yuan Tan Qingzhou, Neutron Youzhou and his nephew Bing. Sowed the seeds of division. "Biography of the Three Kingdoms Yuan Shaozhuan" records: "After our army was defeated, we fell ill and worried about death for seven years." Hebei was finally destroyed by Cao Cao because it fell apart. Cao Cao finally unified the north.

Later, Yuan Shao sent his troops against Cao Cao's army many times, and they were all defeated without exception. As for the joint operation between Yuan Shao and Cao Cao, although Yuan Shao won, isn't it normal for Yuan Shao, who already has military advantages, to win? Instead, Cao Cao came out to fight Yuan Shao, who had the strength advantage but failed to win the first world war. This in itself shows that there is a gap in the military quality between the two sides.

Liu Bei led Yuan Shao's army to attack Xuchang. As a result, Coss defeated many with fewer. Later, Zhang He led an army to attack Cao Cao's camp, but the result was still not shot down. Zhang He simply defected. Besides, Cao Cao's 5,000 men defeated Chunyu's 10,000-yuan army and Yuan Shao's cavalry.

We might as well assume that if Yuan's fighting capacity can be improved to a higher level, it is that Wen Chou heroically beheaded Cao Cao in World War I, Liu Bei unexpectedly welcomed Xu Chang to offer the emperor to the Han Dynasty, and Han deprived Ren Jun of food, Zhang He broke Guandu but captured Cao Hong alive, and Chun Yu Qiong fought the Wu Dynasty to turn the corner. It can be said that whoever wins a game, Yuan Shao has already won, but history is cruel. Yuan Shao has lost all the local battles, so it is no wonder that the leader became a pessimistic counselor before the war, and Cao Cao was considered a "lean foot soldier" before the war.

So why did Yuan become like this? This is related to Yuan's combat experience. First of all, let's take a look at the main enemies Yuan Shao faced in Hebei: Black Mountain Thief, Kong Rong and Gongsun Zan. Let's start with the black mountain thief. There are many black mountain thieves, but they are completely rabble. Lu Bu, Cheng Lian, Yue Wei and dozens of other athletes rode the sudden appearance of the swallow array, and all of them were beheaded for three or four days a day. Lien Chan defeated the Yan army for more than ten days.

Although Lu Bu is brave, he still has to come three or four times a day to let Lu Bu come and go freely with dozens of riders from his own army. Isn't the fighting capacity and organizational ability of the Black Mountain Army funny? Worse than the Qingzhou army led by Cao Cao in the early days. As for Kong Rong, that's even more of a joke. Liu Bei said that my 3,000 men could defeat the 40,000-50,000 yellow turban insurrectionary army, but Kong Rong could not cope with a North Sea phase. He has a brave soldier like Taishi Ci.

Let's talk about the first point and beat Zhang Chun. Is Zhang Chun very strong? Not strong, because although Zhang Chun joined hands with Wu Huan, in fact, the main components of the army were farmers and rabble. And Gongsun Zan is actually an accomplice. After all, there is a corps commander Meng above him.

Then the Yellow Scarf Army was defeated. What is the fighting capacity of the Yellow Scarf Party? Need I say more? It's scary to look at the figures, which are always hundreds of thousands or even millions. In fact, they are all married and have children, with low fighting capacity and poor organization.

For Cao Cao, the battle of Guandu is really important. After all, he is invincible, and he will quit the stage of competition with others. However, for the history of the Three Kingdoms in the late Han Dynasty, the battle of Guandu was just a battle, and it was not the so-called "laying the foundation for Cao Cao's unification of the north" at all.

In fact, after the battle of Guandu, Yuan Shao quickly put down the rebellion in Hebei and reunited his own strength-

To sum up, the quality of Yuan Shao's army was seriously damaged. Yuan Shao's opponent is not bad, but when he really meets his nemesis, Cao Cao, he finds that he can't win. After all, the correct strategic deployment needs to be completed, and Yuan Shao's military quality obviously can't do this. In the end, Cao only seized the rare opportunity to win.
