According to Records of Rites and Music in the History of Han Dynasty, when Emperor Wudi was in power, there was an organization that collected local ballads, arranged and made music scores, called Yuefu. Later, people called the poems collected and created by this institution Yuefu Poetry, or Yuefu for short. By the Tang Dynasty, although the scores of these poems had long been lost, this form followed, becoming a poetic genre with no strict meter and close to five or seven words.
Expanding Information Poets in the Tang Dynasty wrote Yuefu poems, some of which used old Yuefu poems to express their feelings about current events, such as "Saishangqu" and "Guan Shanyue", while others wrote new poems to reflect real life.
In Song Dynasty, Guo Maoqian collected all Yuefu poems and compiled Yuefu poems, such as Mulan Poetry (Southern and Northern Dynasties).
