We all know that at the end of the Eastern Han Dynasty, after countless wars, countless ingenious schemes, and deception, the three big men who led these three countries were: Sun Quan in Jiangdong, Liu Bei in Shu, and Cao Cao in the north.
However, Cao Cao, the strongest of the three forces, immediately started the idea of the south after unifying the north, thus igniting the battle of Chibi. However, under the blows of Sun Liu's union, he was defeated back to the north. After that, Liu Bei used Jingzhou as his base and marched to Shuzhong with the intention of capturing Yizhou, and finally, with the assistance of Pang Tong and others, successfully occupied Yizhou, established the Shu Han regime, and established himself as emperor, while Guan Yu remained in Jingzhou.
During the Three Kingdoms period, Jingzhou was the belly of the world and a very important strategic place. Such a place is naturally also a place where soldiers must fight. Although Cao Cao was defeated at Chibi, he also created something that he felt was very valuable, that is, to leave a gap in the seemingly airtight alliance between Sun Liu and let the wind blow in, and this gap was the ownership of Jingzhou, he knew that Liu Bei occupied Jingjing, Sun Quan was definitely unhappy, and Liu Bei ostensibly said that he did not want to return at all, and after a long time, the two alliances would be useless, and war would be inevitable.
Sure enough, Sun Quan eventually fought for Jingzhou by force and killed Guan Yu. Sun Liu's alliance also completely collapsed with the loss of Jingzhou, causing Sun Liu's two families to turn against each other, and Liu Bei was so angry that he raised troops to fight against Sun Quan.
In fact, if you think about it carefully, there is a big problem here, what kind of role is Sun Quan, doesn't he know the brotherhood between Guan Yu and Liu Bei? If you kill Guan Yu, it will inevitably make Liu Bei more angry, isn't this self-inflicted? Originally, using force to seize Jingzhou was already a big blow to Liu Bei, and killing Guan Yu again could simply make Liu Bei crazy? Didn't Sun Quan push himself into a fire pit by doing this? It should be known that the "reason" for Liu Bei to launch the Battle of Yiling was to avenge his brother Guan Yu. Then why didn't Sun Quan simply let Guan Yu go at the beginning and sell his personal feelings to Liu Bei, so that although Jingzhou did not lose anyone, it could also be regarded as letting Liu Bei, who had always been benevolent and righteous, calm his anger?
Think about it again, everyone is not stupid, since ancient times in the face of imperial power struggles and national wars, any brotherhood is false, Liu Bei can share happiness and hardships with you when he is in trouble, and once he gains power, he may not be able to share wealth with you. Sun Quan was not stupid, he clearly realized this, even if Guan Yu was really released, Liu Bei would also raise troops to take Jingzhou, which also gave Liu Bei a terrible general, so that Liu Bei Fang had an extra chance of winning, so he simply killed Guan Yu to eliminate the troubles.
So suppose Guan Yu was really released by Sun Quan, what would Liu Bei do? Everyone is very aware that the strategic position of Jingzhou during the Three Kingdoms period is very important, without him, liu Bei wants to enter the Central Plains to dominate the world, Guan Yu made such a big mistake, not to kill can not serve the public. But if he was really killed by himself, he would also make Liu Bei, who has always been serious in the eyes of everyone, immediately bear the charge of ruthlessness and injustice. Therefore, in the end, Xiaobian believes that the more compromised approach is to let Guan Yu dai sin and make meritorious contributions to the crime, to take Back Jingzhou, which should be the reason why Sun Quan resolutely killed Guan Yu.
The competition between the three countries is definitely an IQ contest, and every action done by any party cannot be regarded as an individual's behavior, but should be considered as an overall consideration. It is precisely because of this that the Three Kingdoms era can be described as a variety of intrigues, which enriched this history of singing and weeping.
