In the early Han Dynasty, Yuefu did not exist. When Emperor Wu of the Han Dynasty arrived in Liu Che, he rebuilt Yuefu when he held a ceremony in the suburbs. Its duty is to collect folk songs or literati's poems for music, so as to prepare for the court's performance at sacrifices or banquets. The poems it collected were later called "Yuefu Poetry" or "Yuefu Poetry" for short.
Qin Yuefu is not called Han Yuefu.
