"Historical Records: Benji" mainly writes about emperors, and almost every emperor has its own chapter. Even Xiang Yu, the overlord of Western Chu, although he did not officially proclaim himself emperor, Sima Qian also gave a comprehensive outline and narration of it, which was brilliant and touching. These representative character stories or historical events, as well as the emperor's courage and strategies, reflect the historical development and evolution of China's feudal society and the trajectory of the rise and fall of dynasties.
