What did Xiang Yu express through Wujiang Pavilion?

This poem, like the poem "Red Cliff", discusses the success or failure of the war and puts forward its own assumptions about the war that has ended in history. In the first sentence, victory or defeat is a common occurrence in military strategists. The second sentence criticized Xiang Yu for not being broad-minded and lacking fearless spirit.

Degree. Imagine three or four sentences, if Xiang Yu returns to Jiangdong and regroups, maybe he can make a comeback. This sentence has some pity for Xiang Yu who committed suicide in anger, but the main meaning is to criticize him for not being good at grasping opportunities and listening to others' construction.

Discussion, not good at employing people. Sima Qian once criticized Xiang Yu's stubbornness of "killing me by heaven is not a crime of war" from the perspective of historians. Du Mu, on the other hand, talks about success or failure from the perspective of a military strategist. Both of them pay attention to personnel, but Sima Qian summed it up.

Learned lessons and emphasized the reasons for failure; Du Mu is an imaginary opportunity, emphasizing that military strategists should have foresight and indomitable will.
