It is a style that emphasizes literary talent and rhythm and has the nature of poetry and prose. Its main characteristics are: "scenery-oriented, scenery to convey feelings." The one that first appeared in hundred schools of thought's essays is called "short fu"; The "Sao Style" represented by Qu Yuan is the transition from poetry to fu, and the fu at this time is called "Sao Fu"; The style of Fu was formally established in the Han Dynasty, which is called "Ci Fu". After Wei and Jin Dynasties, it developed in the direction of parallel prose, which was called "parallel prose". In the Tang dynasty, another parallel body was transferred to the legal body, which was called "fa fu"; Prose Fu from Tang Dynasty to Song Dynasty is called "Wen Fu". Such as Tu Mu's Epang Palace Fu.
It originated from The Book of Songs. In the history of China literature, Fu, as a unique style, has always been attached importance by scholars, especially Han Fu, which greatly expanded the expression space of China literature in terms of subject matter, genre, expression technique and aesthetic form. Therefore, since the Selected Works, Fu's creation has often been placed in the first place in the collection of literati. However, what is Fu, that is, which style can be called Fu, which style can't be called Fu, and what is Fu, that is, whether Fu belongs to poetry or prose or another style, is still a question that needs to be considered.
