Together with Mulan's poems, they are called Yuefu poems.

Peacock Flying Southeast in the Han Dynasty and Mulan Poem, a folk song in the Northern Dynasty, are both called "Yuefu Shuangbi". These two poems are long narrative poems, which have profound social and ideological significance and high artistic achievements, and are highly praised by scholars in past dynasties.

Yuefu Shuangbi: The so-called Yuefu Shuangbi, namely Mulan Poetry and Peacock Flying Southeast, are the two most famous representative works of ancient Yuefu folk songs in the Han Dynasty. Mulan poetry, also known as "Mulan Ci", is a folk song of the Northern Dynasties.

Peacock Flying Southeast, also known as "Ancient Poems for Jiao Zhongqing's Wife", is one of the representative works of ancient folk songs in Han Dynasty and the earliest existing long narrative poem. Peacock Flying Southeast is based on a marriage tragedy in Lujiang County (now Anhui Province) during the reign of Emperor Xian of the Eastern Han Dynasty.

Yuefu Shuangbi introduced:

Peacock Flying Southeast was originally a folk song, which may have been polished by later scholars. This story tells the story of a woman named Liu Lanzhi who was beautiful, kind, intelligent and hardworking during the Jian 'an period in the late Han Dynasty. After she married Jiao Zhongqing, the couple respected each other, loved each other and had deep feelings. Unexpectedly, the stubborn mother Jiao looked at her with unhappy eyes, was critical in every way, and bullied her into firing her.

Jiao Zhongqing was forced by her mother's orders, but she had to persuade Lan Zhi to stay away from her family until she tried to take her home in the future. When they broke up, the two vowed never to lose each other. Who knows that after Lan Zhi returned to her mother's house, her flattering brother forced her to remarry the son of the satrap. Jiao Zhongqing rushed to the scene, and the two agreed to "meet under the grave". On the wedding day of the satrap's son, both of them died of double suicide.
