The form discussion studies Liang Zongdai and Ye Gongchao respectively introduced and spreaded the French imagism and British and American formalism. The Poem special issue in the literature and art supplement of Ta kung Pao Newspaper and New Poetry organized twice discussions in poetic forms. The pure poetry school introduced that the modernists introduced the western and ancient pure poetry theories: from Baudelaire, Mallarme, Vale'ry, H. Read, A. Bremond to J.M. Murray, and the basic idea and difference of pure poetry. Besides, a lot of modem poets became greatly interested in pursuit heat of the pure poetry in late Tang and Nan Song dynasties, studying the development and variation of pure poetry. Music theory argues that modernists make introduction and reform on the western and Chinese music theory. He Qifang and Bian Zhilin continue the topic to the contemporary time, and put forward the theoretical frames in Chinese poetry. Rhyme and rhythm theory make researches on the introduction and reform of French symbolism and British and American modernists' rhyme and rhythm theory, making studies on the Chinese new form poetry and its thyme and rhythm theory.
