Crescent School is an important school in the history of modern new poetry, influenced by Tagore's Crescent Collection. Generally speaking, the poetry school is divided into two periods: 1927 period. The early stage started from the spring of 1926, and the main members were Zhu Xiang, Rao Mengkan, Sun Dayu, Liu Hewen Yiduo and Xu Zhimo.
Wen Yiduo put forward the famous thought of "three beauties" in his poetic meter, namely, "the beauty of music (the beauty of syllables), the beauty of painting (the beauty of words) and the beauty of architecture (the symmetry of sections and the neatness of sentences). It was put forward in view of the scattered form of new poetry at that time. This proposition laid the theoretical foundation of the new metrical school and made some contributions to the development of new poetry.
In the later period, the Crescent School put forward the principles of "health" and "dignity", adhered to the position of "pure poetry" which was super-utilitarian, self-expression and aristocratic, and emphasized "purity of essence, thoroughness of technique and rigor of meter". However, the artistic expression and lyricism of poetry are close to modernist schools.
