Free verse came into being in modern times, which is a new form used by poets when they can't express what they want to express well with traditional poetic forms. It is creative, enriches the form of poetry and is conducive to the development of poetry. Whitman, an American poet, is the founder of free verse, and Leaves of Grass is his masterpiece.
After the May 4th Movement, China began to use vernacular writing in his poetry creation, demanding to get rid of the limitations of traditional poetry in rhythm, syllables, paragraphs and verses, and to express richer thoughts and feelings, so the embryonic form of free verse appeared. Hu Shi and others have made many attempts and efforts to get rid of the influence of the old poetry meter. Guo Moruo's Goddess is an anthology of China's free poems, which breaks the shackles of old poems in content and form and shows the spirit of complete rebellion.
Free verse is hardly restricted by any form in writing. The author can describe what he wants at will, express his strong feelings, and fluctuate with the author's intention. However, although excellent free verse is eclectic, it does not mean perfunctory. The so-called "freedom" is often the crystallization of repeated conception and deliberation by poets without "freedom". "Concise and concise, generally neat and rhyming" is a common feature of many free poems.
