The criticism of ancient Chinese novels seems to be complicated and messy, but as long as they are sorted out, they can be broken into pieces. Among them, the “based on scriptures” argument around the function and value of the novel can form its own pedigree. On the one hand, in response to some Taoists' theories about novels such as “exoticism” and “vulgarity”, novel critics often use the Six Classics, which is “emotional moral education” to defend the relationship between men and women in novels as “Confucian classics” and “elegance”. On the other hand, in response to certain accusations of the “fiction and absurdity” based on the historian's “faithfulness” principle, novel critics often “refer to the classics” to refute, emphasizing that the narratives of novels are reasonable. In the end, in order to adjust the difference between the stubborn “jing” (classics) and “non-jing” (non-classics), critics of ancient novels often followed the “Yin and Yang” or “opposite mutual formation” originated from Book of Changes and other classical thinking and deduced that the “coexistence of the direct and indirect” was a series of dialectical discourses, such as “elegant and vulgar appreciation” and “solemnity and humor”.
