What is the theme of the decline of The Book of Songs? Yu Guanying's statement is the most appropriate.

1, Yu Guanying thinks that "this is the complaint of the convict" (The Book of Songs) is the most incisive poem.

2. Every chapter of this poem begins with "Decline, Decline, Hu Bugui". It's dark, it's dark, why don't you go home? The poet then confessed the reason: "Because of the micro-monarch, Hu Lou is exposed in the middle"; "The bow of Weijun is in the mud." It means to work day and night in the dew and mud all year round for the monarch and to support his noble body. In just two chapters and a few words, the inhuman situation of the enslaved people and their resentment against the rulers left a deep impression on the readers.
