The "three beauties" proposed by Wen Yiduo, namely "the beauty of music, painting and architecture", are the theoretical basis of the new metrical poetry school. To some extent, it overcame and corrected the shortcomings of loose and casual vernacular poetry since the May 4th Movement, and made a unique contribution to the healthy development of modern poetry in China.

Specifically, "musical beauty" emphasizes "musical scale, flatness and rhyme"; "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 "the symmetry of nodes and the uniformity of sentences". Its main purpose is to have beauty in the content and format of poetry.

Extended information:

Wen Yiduo not only has a well-known concern for current affairs and a sense of justice, but also has an unfailing childlike innocence. In artistic creation, he often looks at things in life with childlike curiosity and unique eyes. Therefore, many of his poems are full of youthful childlike interest. Through these images full of childlike interest, people can feel the poet's childlike and romantic imagination.

For example, "the sun" is a common image in Wen Yiduo's poems. In China's classical poetics, "the sun" is generally a symbol of warmth, hope, light or noble personality. However, in his poems, "the sun" has a different meaning. For example, in the three poems Asahi, Sun Yin and Look, "Sun" is creative, and is imagined as "master", "swift sun" and "sleeping silkworm" respectively, full of infinite childlike interest.

The three are between ontology and vehicle, so it is difficult for readers to find an appropriate and appropriate connection point. This metaphor is neither similar in shape nor spiritual in spirit, but it is very harmonious when applied to the whole poetic realm. This is the result of Wen Yiduo's bold creation by getting rid of the stereotyped thinking habits of adults and using childlike naive romantic fantasies.
