"I don't know how to make a comeback" is the most powerful sentence in the poem, which means that there are still many things to do if possible; Unfortunately, Xiang Yu refused to put down his airs and commit suicide.
This provides a strong basis for the above sentence or two, and it is quite imposing to see the situation of "Jiangdong children" and "stage a comeback" in one go. At the same time, while regretting, criticizing and satirizing, it also shows the truth of "not losing grace", which is also quite positive.
Appreciation of Jiangting Pavilion
This poem discusses the success or failure of the war and puts forward its own hypothetical speculation 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 enough and lacking general bearing.
Imagine three or four sentences, if Xiang Yu returns to Jiangdong and regroups, maybe he can make a comeback. This poem regrets Xiang Yu's anger and suicide, but the main meaning is to criticize him for not being good at grasping opportunities, listening to other people's suggestions, and being good at employing people.
