Zheng Guofeng Wind in Zi Jin is a poem in The Book of Songs, the first collection of poems in ancient China. The author is anonymous. The whole poem consists of three chapters, each with four sentences.
As for the background of this poem, Preface to Mao Poetry says, "It is a thorn in the school, but in troubled times, the school has not cultivated it. "On Confucius and Ying Da": "The state of Zheng declined and failed to repair the school. Scholars scattered, or left or stayed, so those who stayed hated the words of those who left, so they abolished the school by stabbing. These three chapters are all Chen's reproaches. Zhu said in Biography of Poetry, "This is also a dissolute poem. "
