Crescent school: an important school of poetry in the history of modern new poetry, generally divided into two periods by 1927. The early stage began in the spring of 1926, supplemented by Beijing Morning Post? Poetry magazine is the front, and its main members are Wen Yiduo, Xu Zhimo, Zhu Xiang, Rao Mengkan, Sun Dayu and Liu. They are dissatisfied with the style of "free poets" who ignored the art of poetry after the May 4th Movement, advocate new metrical poetry, advocate "rational emotional control", and oppose the promiscuity and prosaic tendency of poetry. From theory to practice, they made a serious exploration of the new poetic meter. Wen Yiduo put forward the famous thought of "three beauties" in "The Metre of Poetry", that is, "the beauty of music, the beauty of painting and the beauty of architecture". Therefore, the crescent school is also known as the "new metrical poetry school". The crescent school corrected the weakness of the early poetry creation that was too informal, and also made the new poetry enter the period of conscious creation. /kloc-in the spring of 0/927, Hu Shi, Xu Zhimo, Wen Yiduo, Liang Shiqiu and others founded Crescent Bookstore, and the monthly magazine Crescent was founded the following year. The main activities of the "Crescent School" moved to Shanghai, which was later the Crescent School. Its main positions are New Moon and Poetry, which were founded in 1930. The new members are Chen, Fang and Bian. 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. The beauty of music in the "three beauties" means that each section of the new moon poem is different, just like music. Architectural beauty means that the format of poetry is like architecture. The beauty of painting is that every paragraph of a crescent poem can be painted.
