Wen Yiduo's "three beauties of poetics" are "beauty of music, beauty of painting and beauty of architecture". "Musical beauty" emphasizes "there are scales, levels and rhymes"; The Beauty of Painting emphasizes that the choice of words should be rich, 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.
Wen Yiduo's thought of "three beauties" of new poetry laid the theoretical foundation of the new metrical poetry school, overcame and corrected the cultural tendency of loose vernacular poetry and prose to a certain extent, and the poetic theory of "three beauties" better embodied Wen Yiduo's purpose of establishing the artistic form standardization of China's new poetry.
