Fu, often translated "rhapsody" or "poetic exposition", is a form of Chinese rhymed prose that was the dominant literary form in China during the Han dynasty. Fu are intermediary pieces between poetry and prose in which a place, object, feeling, or other subject is described and rhapsodized in exhaustive detail and from as many angles as possible. They were not sung like songs, but were recited or chanted. The distinguishing characteristics of fu include alternating rhyme and prose, varying line lengths, close alliteration, onomatopoeia, loose parallelism, and extensive cataloging of their topics. Classical fu composers tended to use as wide a vocabulary as possible in their compositions, and therefore fu often contain rare and archaic Chinese words and characters.

The Wen Xuan, usually translated Selections of Refined Literature, is one of the earliest and most important anthologies of Chinese poetry and literature, and is one of the world's oldest literary anthologies to be arranged by topic. It is a selection of what were judged to be the best poetic and prose pieces from the late Warring States period to the early Liang dynasty, excluding the Chinese Classics and philosophical texts. The Wen Xuan preserves most of the greatest fu rhapsody and shi poetry pieces from the Qin and Han dynasties, and for much of pre-modern history was one of the primary sources of literary knowledge for educated Chinese.
