Abstract: Most of us hold the misunderstanding of the Records of the Grand Historian that Sima Qian was full of admiration for General Li Guang while kind of critical of General Wei Qing. Reading and studying the Records of the Grand Historian in detail may lead to the conclusion that Sima Qian didn't write in a discriminatory way out of family background but depicted Wei Qing's image elaborately, sparing no efforts to portray his heroic contributions and achievements. On the contrary, he is critical of Li Guang's narrow-mindedness. This is a reflection of Sima Qian's spirit of true history.
