But these are only written in books. In Romance of the Three Kingdoms, Zhou Yu was annoyed by Zhuge Liang, but not in real life. In order to make Zhuge Liang shine infinitely, Luo Guanzhong wrote Zhou Yu as a narrow-minded person. After all, without comparison, he can't highlight Zhuge Liang's ingenuity.
Historically, Zhou Yu actually died because of the attack of a hidden disease, and he died in his prime. In the past, it was said that the death of Zhou Yu Sun Ce was related to Daqiao Xiaoqiao. Because Cao Cao liked wives and wanted Daqiao Xiaoqiao, Zhou Sunyuce died early. Later, he said in his book that Zhou Yu was angry with Zhuge Liang.
But it's really not. You can imagine how Liu Bei, Zhou Yu's contemporary, commented on Zhou Yu's tolerance. Jiang Gan said that Zhou Yu was generous. How could such a person be sad? Besides, winning or losing is a common occurrence for military strategists. If it is really so easy to make people feel sad, then Cao Cao and Liu Bei may really defeat the invincible hand in the world. After all, it is enough to piss off the enemy. Zhuge Liang's empty plan can piss off a senior general of the enemy. You don't have to fight this battle at all, just grieve over it.
Zhou Yu was in excellent health before. In a war, he was shot by an arrow because he was brave, and buried a hidden disease. Coupled with Zhou Yu's overwork, Zhou Yu died on his way home to find Sun Quan. Of course, it does not rule out that it is because of Sun Quan's political persecution. After all, there were many people spying on Zhou Yu's position at that time.
