Mulan Poetry is a collection of folk songs divided into two main parts, ( ) and ( ).

The Mulan Poem is a folk song from the north of China during the Northern and Southern Dynasties, and is taken from a collection of poems compiled by Guo Maoqian in the Song Dynasty. The folk songs in this collection are divided into two main parts, namely, the "Songs of Wu" and the "Songs of Western Songs".

The "Lefu Twins" is a metaphorical name for the "Mulan Poem" and the "Southeast Flight of the Peacock". Mulan Poetry, also known as Mulan Rhetoric, is a folk song of the Northern Dynasties; Southeast Flight of the Peacock, also known as Ancient Poetry for Jiao Zhongqing's Wife, is one of the masterpieces of the ancient Lefu folk songs, and one of the earliest preserved full-length narrative poems.

The Mulan Poem, a folk song of the Northern Dynasties, is also one of the rare and excellent long narrative poems in China's classical poetry, selected from the Collection of Lefu Poems edited by Guo Maoqian of the Song Dynasty. It is more than 300 words long. It is about a young girl, Mulan, who joined the army on her father's behalf, portraying the image of a heroine who went to the frontiers and won many battles without losing her character as a laborer. This artistic image breaks the traditional feudal concept of "women are inferior to men". It is a combination of realism and romanticism. The language of the poem is rich and colorful, ranging from simple and natural colloquialisms to subtle and neat metrical lines. The stanzas are either neat or scattered, of different lengths, and the repetitions of chants and metaphors enhance the musicality and expressive power of the poem.

"Southeast Flight of the Peacock" is the name of a poem in the Han Lefu style, so named because its first line is "Southeast Flight of the Peacock". It was first published in Xu Ling's Jade Terrace New Rhymes in the Chen Dynasty, and is titled Ancient Poem for Jiao Zhongqing's Wife. The poem, with more than 1,700 words, is one of the earliest long narrative poems preserved from ancient China. It is the earliest long narrative poem preserved in ancient China. It is through the marriage tragedy of Jiao Zhongqing and Liu Lanzhi. It powerfully exposes the evils of feudalism and feudal patriarchy, and warmly praises the struggle of Lanzhi and her wife, who would rather die than give in to the evil forces of feudalism in order to be faithful to their love. Southeast Flight of the Peacock is a high artistic achievement, successfully portraying several distinctive characters, through which the theme of anti-feudalism is expressed. The language of the poem is simple and fluent, with strong lyricism in the narrative, and the description is pompous and prose, making it a representative work of the pentameter narrative poems of the time.

These two long narrative poems, with their shocking heroic stories and strong spirit of resistance, as well as deep and broad ideological content and perfect artistic form, have become a pair of jewels radiating strange colors in the treasury of China's poetry, known as the "Jewel of the House of Music," and have been loved by the people of all times
