The reason for this result is vividly described from beginning to end in the article Xiang Yu's Biography. For example, it is impossible to write that Xiang Yu learned books and swords when he was young, but he has his own reason: "The book is enough to register his surname. The sword is an enemy, not enough to learn, but to learn from ten thousand enemies. " It means that reading and writing can only be used to remember names. Fencing can only deal with one person, and it is not worth learning. Learn the skills of dealing with thousands of people.
What he said shows that he just wants to do it overnight, but he doesn't know how to accumulate his theoretical knowledge and practical experience step by step, so that he has enough experience to deal with various situations in the war. Later, his uncle told him to learn the art of war, but "he didn't learn" and gave up halfway.

Chronicles in Historical Records, centering on emperors of past dynasties, describe the ups and downs of various dynasties and major political events. Although Xiang Yu did not succeed in imperial industry, Sima Qian listed Xiang Yu as the hegemon in this century because he issued decrees in the peasant war in the late Qin Dynasty and the Dingge period in Qin and Han Dynasties, claiming to be the hegemon.
Biography of Xiang Yu vividly and profoundly describes Xiang Yu's life by describing the broad historical scene of the peasant uprising and the dispute between Chu and Han at the end of Qin Dynasty. Xiang Yu is not only a hero who pulled out the mountain with great strength, but also a violent, indecisive man who only knows how to use force but doesn't know what to do. Sima Qian skillfully unified all aspects of contradictions in Xiang Yu's character into this masterpiece. Although there is no lack of profound criticism, it is more sincere regret and sympathy.
In historical records, most of the records in Historical Records are emperors, among which Xiang Yu did not become an emperor. Sima Qian's classification in Historical Records shows his respect for Xiang Yu.
