New poetry advocated by the crescent school. The "three beauties" put forward by Wen Yiduo, namely "the beauty of music, painting and architecture", laid the theoretical foundation of the new metrical poetry school. To some extent, it has overcome and corrected the shortcomings of rambling vernacular new poetry since the May 4th Movement, and made a unique contribution to the healthy development of modern new poetry in China. Specifically, "the beauty of music" emphasizes "there are scales, levels and rhymes"; "Beauty of painting" emphasizes that the choice of words should be beautiful, vivid and colorful; Every poem can form an independent picture. "Architectural beauty" emphasizes "symmetry of nodes and unity of sentences". Its main purpose is to have beauty in the content and form of poetry.

The May 4th literary revolution initiated a discussion on China's old dramas, criticized the degenerate civilized dramas and translated and introduced European and American dramas.

Pure poetry, the concept of "pure poetry" was put forward by the early symbolist poet Mu Zai 1926- in a letter to Mo Ruo. Mu Tianmu's so-called "pure poetry" includes two aspects. First, poetry and prose have completely different fields. He advocates that "the world of pure expression gives the field of poetry and human life gives prose"; Second, poetry should have a different way of thinking and expression from prose. "Poetry should be implicit, and poetry should be the most taboo to explain." From a deeper perspective, the concept of "pure poetry" put forward by early symbolist poets means a change in the concept of poetry: from emphasizing the expressive function of poetry to expressing self-feelings.
