Who killed Guan Yu?

Guan Yu's death, in addition to his personality and the decision-making factors of Shu Han (most of these answers will be mentioned, so I won't go into details here), there is also an invisible factor, that is, the arrangement of things is too perfect, and the extremes meet!

When Soochow attacked Jingzhou, Guan Yu was not unprepared. Instead, he made corresponding arrangements:

Up and down the river, or twenty miles, or thirty miles, choose Gaofu to dispose of a beacon tower, with fifty soldiers guarding each station; If Wu Bing crosses the river, there will be open flames at night and smoke signals during the day. I should call myself. Chengdu also shelved its aid to Jingzhou because Guan Yu built a beacon tower.

Suddenly someone came from Jingzhou and said that Wu Dong proposed to Guan Gong, but Guan Gong refused. Zhuge Liang said: "Jingzhou is in danger! Can make people return Guan Yu "and suddenly explore the horse. It is reported that Guan Yu set more piers on the river, so he was very careful and foolproof. Therefore, Liu Bei was relieved. It can be seen from the above points that both Guan Yu in Jingzhou and Liu Bei in Chengdu have placed their hopes on these beacon towers intentionally or unintentionally. Guan Yu's first reaction when he heard that Jingzhou was ambushed was, why not light a fire on the river?

Ray Dylan, who was guarding Jingzhou, directly deceived the people to open the gate without any decent resistance or even any vigilance. Why is this happening? Pan Zhuo's lack of strength is one of the factors, and the other is that he pinned his hopes on the beacon tower.

Pan Zhuo's rule of Jingzhou itself is not a suitable candidate. At that time, Wang Fu, the marching Sima, had proposed it when he accepted the order to build a beacon tower. However, Guan Yu was rejected by one vote. First, the personnel arrangement has been decided, and frequent changes are not good. Secondly, Zhao Lei, Wang Fu's successor, is also a very important job. In addition to these two points, Guan Yu believes that the beacon tower has been built, and these mistakes in arrangement can be completely made up. When all the beacon towers were built, Guan Yu's worries about the rear completely disappeared.

As Laozi said: Happiness is always dangerous. The seemingly perfect layout actually hides a huge crisis. If you think that some preventive measures can resolve the crisis, then let your guard down. Then disaster is not far away!
