Bai Juyi. "When articles are written, songs and poems are written in things" comes from Nine Books with Yuan Dynasty written by Bai Juyi, a poet in Tang Dynasty, which is the program of "New Yuefu Movement". It is not only an ancient maxim, but also a concentrated summary of the sense of historical mission endowed by scholars of past dynasties. Among them, "he" means "should", and the whole sentence means: articles should be written for the times, and poems should be written for practical things. It emphasizes the close connection between literary works and social reality, reflects real life, and also reflects the author's concern and sense of responsibility for society.
Bai Juyi put forward the idea that "articles should be written in time and songs and poems should be written for things" in the middle Tang Dynasty. At that time, social contradictions became increasingly acute, politics was dark, and people's lives were difficult. Therefore, Bai Juyi advocated that "articles should be written in time and poems should be written". He hoped to expose social problems through literature and called for reform. He advocates that literature should be close to reality and serve the society.
