In Han Dynasty, people called the poems sung by Yuefu "songs", and after Wei and Jin Dynasties, they were also called Yuefu. The name of Yuefu-governed music institution began in Qin Dynasty. During the reign of Emperor Wu of the Han Dynasty, its scale and functions were greatly expanded, and the function of "collecting poems" appeared. "Since the filial piety, Yuefu children have adopted songs, so there is Scott's obituary and Qin Chufeng.
