There are also comments in the book, but the author's complaints have nothing to do with the overall situation. It turned out that Sima Qian had been troubled by Li Ling and worked harder to write books. He felt that he was in ruins, and there was only one way to express his frustration. He quoted Wang Xia's words to Han Fei's sages in Ren An Shu and Historical Records Biography Preface, which were written only after (vigorous/angry). He is a cynical writer himself. The impermanence of heaven and the impermanence of the world made him cry: he sympathized with others and complained. This adds to the charm of his book. Later, people who wrote papers respected historical records.
One reason is here.
