The Book of Songs? It is the earliest collection of poems in China, including 305 works from the early years of the Western Zhou Dynasty to the mid-Spring and Autumn Period. According to the nature of music, it is divided into three parts: wind and elegance. There are fifteen national styles in Wind, which are mostly written orally by working people: "Ya" is the music of the land of kings, which is divided into "Elegance" and "Xiaoya", and most of them are composed by nobles and literati; Ling is a dance music used in temple fairs, which is divided into three parts: Shang Song, Zhou Song and Lu Song.
therefore
"Guanju" and "Jiaxu" should be based on "wind".
If satisfied, I hope to adopt it.
