Where did the score of The Book of Songs come from?

The poem "Cutting Tan" is a Wei folk song, which comes from the Book of Songs. There are 3 chapters and 27 sentences, which mostly reflect the dissatisfaction of the middle and lower classes with the upper rulers. This is a poem that mocks and rebukes the exploiters for eating and drinking for nothing.

The whole poem strongly reflects the resentment of the working people against the rulers at that time, and also realizes the awakening of the class consciousness of the exploited. Disgruntled slaves boldly demanded justice from parasites and vampires, which is one of the most representative poems against exploitation and oppression in the Book of Songs.
