Taking literature as poetry is a controversial topic in the history of China's poetry. Some people think that it opens up a new field of poetry and enriches the artistic expression of poetry. Deniers think that it confuses the boundary between poetry and prose, and regards prose as poetry "whether it is true or not". Taking prose as poetry is not only a phenomenon of Han Yu's poetry creation, but also a phenomenon of many descendants of Han Yu. "Wen", which takes Wen as poetry, is not limited to the ancient prose advocated by Han Yu, but has extensive extension and expansion; It can be said that writing poetry has an endless history after Han Yu.
Poetry based on literature is an important event in the history of China literati poetry. "Poem by writing" enriches the expression methods of poetry, expands the expression content of poetry, provides beneficial enlightenment for Su Shi's later "Poetry by words" and has a far-reaching impact on the development of China's poetry after the Tang Dynasty. The reason why Su Shi's poems in later generations can be compared with Li Bai's "Flying high in the sky" and Du Fu's "The establishment of Qiao Yue" is that he took prose as poetry and opened up a new realm of "flowing water".
