What is the reason why Liu Bei killed Zhang Yu?

The reason is that Changyu mastered a power that threatened Liu Bei's sovereignty, but Zhuge Liang probably didn't realize it, so that Zhuge Liang pleaded for Liu Bei before trying to kill Changyu.

As far as reputation is concerned, this man can be called the first stick of Shu Han, and his predictions are accurate in his life. This is a rather terrible thing. You should know that more than 30 years ago, the three brothers Zhang Jiao started the Pentecostalism in northern Shu and Han Dynasties. In the eyes of ignorant people, such a great god figure is far more convincing than Liu Bei's regime.

As far as ability is concerned, this person is called the second, and no one is called the first. This person has the strongest ability in Shu Han. Throughout the ages, the theory of divination has been strictly controlled in the imperial family. The Eastern Han Dynasty was a period when "divination" prevailed, and mastering its way could completely influence public opinion.

On current affairs, Liu Bei captured Bashu in Liu Zhang. Although he didn't kill him, he left behind more or less many old ministers who cared about Liu Zhang's era. Changyu is really a person who doesn't know how to advance and retreat. Previously, he strongly opposed Liu Bei's entry into Shu. Liu Bei was so mean and insulting many times during his reign in Shu, which made Liu Bei very jealous!

On the family background, the Zhang family in the middle of Shu is a local clan, which is deeply rooted and intertwined. In this regard, Liu Bei has always been the object of both wooing and preventing, and Zhang Yu is an important figure in the Zhang family. With this plot, how to prevent it!

In Liu Bei's eyes, this man is already a mortal. For this reason, Liu Bei did not listen to Zhuge Liang's persuasion, and executed Zhang Yu in the downtown area and suddenly died in the street. This shows how much Liu Bei hates this person!
