Should Liu Beiying fight Sun Quan (should Liu Beiying launch the war of Yiling)

Of course, you shouldn't fight. If Liu Bei doesn't fight, he won't be defeated, which makes the later period of Shu in a critical autumn and makes it impossible for Shu's strength to recover for decades. Quote (Wu Dong can help, but it's impossible to find out), if he didn't fight with Sun Quan, he would probably make peace with Liu Bei after winning Jingzhou, because after the battle of Yiling, Sun Quan took the initiative to negotiate with Liu Bei. It is conceivable that Sun Quan did not dare to fight Liu Bei until the crisis. The failure of the Yiling War is inevitable, because Lu Xun's talent is by no means what you said. You can win if you listen to Huang Quan, just as Battle of Red Cliffs Zhou Yu can defeat Cao Cao without Huang Gai's pretence to reduce the fire. . Another thing to add is that at that time, Liu Bei only dispatched 30 thousand troops at most, while Lu Xun had 40 thousand to 50 thousand troops, so Sun Quan was also very strong and could not be destroyed. At that time, if Cao Wei defeated Liu Bei in Hanzhong, it would be in a dilemma. Hanzhong could only be maintained by generals like Wei Yan. Zhuge Liang is resourceful and indecisive, managing internal affairs and doing logistics. His ability to March and fight is limited, and his strategy is thoughtful, but if he carries it out in person, it will be full of loopholes (the Northern Expedition is a good example). . . At that time, Liu Bei's terror will be unstoppable.
