What is prose? There are two concepts: broad sense and narrow sense. Prose in a broad sense refers to all articles that do not rhyme in ancient times. However, there was no such name as "prose" in ancient times; The name "Prose" came into being during the May 4th Movement. In modern times, prose in a broad sense includes all narrative, argumentative and lyrical styles except poetry, novel, drama and film and television literature. For example, Qin Mu said in "Generalized Prose Field" that "all short essays that do not belong to other literary genres but have literary flavor belong to the category of prose". In this way, there is a classification of lyric prose, narrative prose and argumentative prose. Prose in a narrow sense refers to lyric prose. This is because with the development of style, the communication characteristics, biographical literature and reportage in narrative prose have all developed into independent styles, each of which has become a category; Argumentative essay has a special name-prose, which is also separated from prose, leaving only lyric prose, that is, narrow prose.
