Yuefu is a special official institution established since the Qin Dynasty, which is responsible for distributing music, training musicians and collecting folk songs. Han Yuefu refers to the poems collected by Yuefu organs in Han Dynasty. These poems were originally circulated among the people and preserved through Yuefu, which was called "Song Poetry" by Han people and "Yuefu" or "Han Yuefu" in Wei and Jin Dynasties. Poems written by later scholars imitating this form are also called "Yuefu Poems".
Han Yuefu is another great collection of ancient folk songs after The Book of Songs. Different from the Book of Songs (also realism), it created a new style of poetic realism. Women's works play an important role in the folk songs of Han Yuefu. It uses popular language to construct works close to life, from miscellaneous words to five words, and uses narrative writing to describe characters in detail, shaping characters with distinctive personality, complete stories and outstanding stories.
The ideological connotation focuses on describing typical details and opening up a new stage in the development of narrative poetry, which is an important stage in the development of China's five-character poetry style. Han Yuefu has a very high position in the history of literature, which can keep pace with The Book of Songs and Songs of the South.
Shang Mo Sang and Peacock Flying Southeast are both folk songs of Han Yuefu, and Peacock Flying Southeast is the longest narrative poem in ancient China. Peacock Flying Southeast and Mulan Poetry are both called "Yuefu Shuangbi". Peacock Flying Southeast in the Han Dynasty, Mulan Poetry in the Northern Dynasty, and Wei Zhuang's Ode to Fu Qin in the Tang Dynasty are also called "Three Wonders of Yuefu".
