Sima Qian kept the chapter type
本纪 'basic annals' for those who ruled all under heaven.
项羽 never became emperor, but after the fall of Qin he divided the empire among the lords as Hegemon-King of Western Chu, so his annals stand between the First Emperor's and those of
刘邦. The chapter also tells of
鸿门宴 and of his last night at Gaixia, the scene of
霸王别姬.
