Evaluation: Xiang Yu's sorrow is more than his stupidity. Fools abandon history books. Feather was young, and his uncle advised him to learn. Feather was crazy: I can do it, why do I need history books? Feather has broken into this world with divine power, but how can she keep it? Two fools can't think Those who don't read history books and think little, the more useless their brains are, the more they walk with military advisers and don't know the tricks of the Chinese yin. The deeper they get, the more they don't know the defeat, the more beautiful they stay, and the more they don't know how to protect them. This is sad, but also a waste of talent. Three fools don't know how to advance and retreat. However, Jiangdong died underground, but he didn't know the way to advance and retreat. He doesn't know whether to win or fail. He is guarding the surface, not knowing the depth. How can he not fall into someone else's trap? It was because of the rise of Chu Song that he died, and the long knife was broken and the relatives were separated, and Jiangdong was close and self-sufficient. Can such a generation become heroes? If you are mediocre, don't enjoy the glory.
