What is the definition of crescent school?

The pre-crescent school is a group of poets formed by 1926 based on Beijing Morning Post Supplement. It advocates new metrical poetry and "three beauties". Its main members are Wen Yiduo, Xu Zhimo, Zhu Xiang, Rao Mengkan, Sun Dayu, Liu, Yu Zhiyu and others. After the new poetry was basically established, the main task of the Crescent School was to "build an indispensable bridge between the new poetry and the old poetry", and at the same time, the focus of creation shifted from the early vernacular poets' concern for the vernacular, that is, "non-poeticization" to "poetry itself", that is, "making new poetry into poetry". Therefore, the Crescent School put forward the idea of "making the content and form of poetry show the power of beauty". The late Crescent School is the continuation and development of the early Crescent School, with the new poetry column of Crescent Monthly, which was founded by 1928, and Poetry Quarterly, which was founded by 1930, as its main positions. In addition to Xu Zhimo, Rao Mengkan, Lin and other old poets, the basic members of the Crescent School are mainly Central University students Chen and Fang. In the later period, the Crescent School took Xu Zhimo as its main banner. Under the trend that the form of poetry changes from metrical to free development, poetry pays attention to poetic sentiment, returns to the heart, puts forward the principles of "health" and "dignity", adheres to the position of "pure poetry" which is super-utilitarian, self-expression and aristocratic, and emphasizes "purity of essence, thoroughness of techniques and rigor of metrical".
