2, the article is combined with the times, and songs and poems are combined for things. From the book of Nine Yuan written by Bai Juyi, a writer in the Tang Dynasty.
3. The first paragraph of Yuan Jiushu is a preface, which briefly explains the writing purpose and background. In the second and third paragraphs, starting from the genesis of poetry, I put forward my own views on what is the essence of poetry. The fourth to seventh paragraphs list writers and works in the history of literature, describe the general situation of the development and changes of poetry in past dynasties with very concise sentences, and clarify the fine tradition of reflecting reality since the Book of Songs. In the remaining paragraph 12, Bai Juyi talked about his painstaking poetry creation after becoming an official and the great influence of his works. When summing up his creative experience, he focused on the relationship between literary creation and reality and came to the conclusion that "articles are written in time, songs and poems are written in things". This essay is straightforward, eloquent, revealing thoughts and feelings, and the language is unpretentious.
