Which category of The Book of Songs did Guan Ju and Jia Jian come from (The Book of Songs is divided into three parts: style, elegance and vulgarity, and praise)?

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.
