Who is the poet who advocates the three beauties of poetry

Wen Yiduo strongly advocated the "three beauties" of new metrical poems in the poetic world, that is, new poems should have "the beauty of music" (syllables), "the beauty of painting" (words) and "the beauty of architecture" (symmetrical sections and neat sentences). He advocates that poetry should not only be innovative in content, but also pay attention to rhetoric and rhyme in form, so it is called "metrical school".
