What is the development and formation process of the Chinese Poetry Society?

The Chinese Poetry Society has branches in many areas, and its members are widely distributed. For example, Guanju in Shanghai, dialect in Beiping, Shilun in Shandong, Liu Wen in Guangdong, Zang Yunyuan and Linlin in Tokyo. Wang Yaping, the president of Beiping Branch, described the bankruptcy of northern rural areas and the hunger and cold life of urban workers in his poems, which was called "the song of life" by Pu Feng. The Wind in December is a collection of poems, consisting of 26 consecutive poems, which shows the anti-Japanese struggle of Peiping students and the "December 29th Movement". Although rough, it shouted "the roar that shocked the ancient city." Liu Wen of Guangzhou Branch created Song of Bricklayer and Song of Stone Carver, which showed the life of working people and had the characteristics of folk songs. Facing the reality, describing the life of the lower class and praising the national salvation movement are the main contents of the creation of poets in China Poetry Society. They think that their poems are "the powerful anger of poets from personal lyricism to the voice of the times", which was born as the opposite of crescent school and modernism. Cang Kejia, who has similar views and higher artistic level than them, had a great influence on the poetry in 1930s.
