Why did Yasundo's works appear in a period of numerous ethnic customs?

The works of Asondo Why period are introduced as follows:

"Ode to Ya" is mostly a work of the Western Zhou Dynasty, written by nobles, which embodies the dignity of "Elegant Music".

In the Western Han Dynasty, it was honored as a Confucian classic and was originally called The Book of Songs. The Book of Songs is divided into three parts: style, elegance and ode. "Wind" is a ballad of Zhou Dynasty. Elegant music is the official music of Zhou people, which is divided into harmony and elegance. Ode is a music song used for sacrificial rites in Zhou and aristocratic ancestral temples, which is divided into, and Shang songs.

The Book of Songs is rich in content, reflecting labor and love, war and corvee, oppression and resistance, customs and marriage, ancestor worship and feasting, and even astronomical phenomena, landforms, animals and plants.

Language style of The Book of Songs: The language form of The Book of Songs is vivid and colorful, which can often achieve "twice the result with half the effort" and "full of emotion". However, the language style and national style of Ya and Song are different. Most of the chapters in Ya and Song use a strict four-character case, with few miscellaneous words, while there are many miscellaneous words in the national style. In "Xiaoya" and "National Style", repeated chapters and sentences are often used, but they are rare in the aspect of appealing to both refined and popular tastes.
