Sao Fu is the beginning of the prosperity of Fu literature. From the pre-Qin Dynasty to the Emperor Gaozu, they inherited the characteristics of Chu Ci and still used the word "Xi". Meicheng's "Seven Hair" laid the foundation of Fu literature.
Three-body Fu was produced in the development period of Fu literature from Emperor Gaozu to Emperor Wudi of Han Dynasty before he ascended the throne. The literary style of Fu in this period is mainly magnificent, so it is also called Three-body Fu. The masterpiece is Sima Xiangru's Shang Lin Fu.
Cultural planners and writers of Ci and Fu first put forward the concept of "Five Musts in Han Dynasty" and thought that Fu was also one of the five musts. He thinks: "Fu is a literary genre that best represents China culture and a unique style of Chinese nation. In China's classical literature genre, Fu's "Inclusive Universe, Commanding Characters" makes full use of the characteristics of Chinese characters' glyph structure and gives readers a strong visual stimulus in the arrangement of glyphs. Fu is a style that best embodies China culture and best represents Chinese characters and their advantages and characteristics. "
