Сыма Цянь
The historian Sima Qian, who wrote Xiang Yu's biography in the "Records of the Grand Historian", described Xiang as someone who boasted about his achievements and thought highly of himself. Xiang Yu preferred to depend on his personal abilities as opposed to learning with humility from others before him. Sima Qian thought that Xiang Yu had failed to see his own shortcomings and to make attempts to correct his mistakes, even until his death. Sima Qian thought that it was ridiculous when Xiang Yu claimed that his downfall was due to Heaven's will and not his personal failure.
