What's Sima Qian's comment on Li Guang?

Although Sima Qian was dissatisfied with Li Guangdi's experience, he also said, "Don't talk about peaches and plums, think of a way next." To praise him. But it is still a book about good and evil. Li Guang's killing of fallen immortals and Ba's killing are recorded in the history books. Sima Qian did not tamper with history with personal feelings, but tried to be realistic, objective and fair. This further proves that "Historical Records" is the most credible historical book, a veritable "record" and "good history".
