The recent appearance of new poetry not only broke the poetic style of seven words and five languages, but also overthrew the shackles of various informal, flat and unlimited tunes and music. No matter what the topic is, do what you should do (Hu Shi's New Poetics). This proposition became the classic theory of vernacular poetry creation later.
Free verse is born out of the shackles of old-style poetry, striving for liberation in style, syllable and language, showing new characteristics:
The first is to get rid of the stereotyped classical Chinese and add poems to the vernacular. Secondly, in terms of syllable rhythm, we should get rid of the rigid shackles of old-style poetry meter and parallel prose allusion, and pay attention to natural music instead of sticking to rhyme (My Opinion on New Poetry by Kang). In addition, in style, I intend to pursue a kind of unrestrained free expression. Poems are not bound by meter and rhyme, and they pour out their thoughts without scruple. They are neither branched nor rhymed, even if the branches are randomly arranged according to the content of the works, thus forming the main characteristics of the artistic form of free verse. Another notable feature is that the theme of spiritual imprisonment and bondage of various old traditional ideas against feudal autocracy contains more meaning of longing for freedom and personality independence. There are also some works in free verse that praise the significance of labor, praise the fine quality of working people and express their yearning for an ideal society and a bright future.
