What contribution did Hu Shi make to China's modern poetry?

"The great liberation of poetic style" is a theoretical proposition put forward by Hu Shi in the preface of his Trial Collection. In his opinion, if we want to make real vernacular poems and make full use of vernacular words, vernacular grammar and vernacular natural syllables, we must make vernacular poems of different lengths. The great liberation of poetic style is to break all the shackles that bound freedom in the past. Say whatever you say. Only in this way can we have real vernacular poems and express the literary possibility of vernacular Chinese.

19 17 years, Hu Shi published eight vernacular poems in the 6th issue of New Youth Volume 2, which is the earliest new poem in China. The trial collection published by 1920 is the earliest new poetry collection. Under the influence of Hu Shi, other literary revolutions in Teamin Between also published new poems. China's new poetry movement was launched, and China's new poetry was born.
