It is the official institution established by the imperial court to manage music since the Qin Dynasty. Yuefu Order was established in the Western Han Dynasty in 1 12 BC. It was formally established in the period of Emperor Wu of the Western Han Dynasty, collecting and sorting out Han folk music, arranging and composing music, and singing and playing.
The Han, Wei and Six Dynasties were famous for Yuefu folk songs. Yuefu was originally a music institution established by Emperor Wu of the Han Dynasty, which was used to train musicians, make music scores and collect lyrics, among which a large number of folk songs were collected. Later, Yuefu became a poetic name with musicality. Yuefu poems in Han Dynasty are mainly preserved in seven of the twelve categories of Guo Maoqian's Yuefu poems in Song Dynasty. Among them, there are elegant music, 18 songs of worship, and folk songs mainly include harmony songs, dance songs and miscellaneous songs.
The system of collecting poems has a long history in ancient China, which appeared widely as early as the pre-Qin period and was relatively mature in the Western Zhou Dynasty. The person in charge of collecting poems is the poetry collector. Since the pre-Qin period, "poets" began to undertake the important functions of obtaining folk information and understanding folk facts. They mainly collect and record people's feelings, such as life and customs, and compile them, and present them to the monarch in the form of ballads, so as to understand people's thoughts and provide an important basis for their governance.
