The folk songs in The Book of Songs are full of realism, which is recognized by literary historians. It was regarded as one of the Five Classics by the Han people and became a Confucian classic, which enhanced its authority in ancient literature. After the Han and Wei Dynasties, whenever there is a serious tendency of flashy and flowery rhetoric in literary creation, critics will emphasize the fine tradition of The Book of Songs to oppose excessive pursuit of form. Poets and critics pay more and more attention to poetry, and the "sentimental" meaning of poetry is becoming more and more prominent. Regarding Bi Xing, Liu Xie criticized the literati in the Han Dynasty for "being better than daily life, forgetting happiness, learning little and abandoning big, so they thanked Zhou people." For the first time, he clearly distinguished the inferiority of Bi Xing, and thought that poetry creation abandoned the more important Xing, which was far less than the Book of Songs written by Zhou poets. Zhong Rong's evaluation of Zhang Hua's "inspiring the next miracle" is because his poems are "gorgeous in style" and "doing things for Ye Yan". At that time, I said, "The poems between Qi and Liang are colorful and complicated, but they must not be sent, and they often sigh." (Preface to Bamboo Trimming) also emphasizes "prosperity" in order to oppose the "dispute between beauty and beauty" and hope to restore the tradition of "elegance". For example, on the one hand, Li Bai later claimed that "it is not me but who is retro", on the other hand, he emphasized "profound interest"
("Poetry His Ability"); Until the North Korean scholar Xu said that "the five words in Han and Wei Dynasties are more profound than others, which covers people's elegance" (Distinguishing Poetry Style), they are all "auspicious" from the requirements of carrying forward the fine tradition of the Book of Songs.
