Whose story did the word "remain uncorrupted" first come from?

Source: Yuan poem "The Second Rhyme of Wujiang Road": "Two sleeves are breezy, sticks and quinoa go with the moon."

Wei Yuanchu's poem "Sending Yang Jimei": "Making friends is like silk, and the two sleeves are cool and a bunch of poems."

Original source: The poem "Xie Zhuqian" in the Northern Song Dynasty: "The sleeves are full of clear wind and the autumn moon is light, and Tao Qian is all over the chrysanthemum fence."

According to the classic meaning: Ming Yuqian's poem "Seven Wonders Going to Beijing" says: "It's not a short story that the wind blows away."

There is nothing in the sleeve except the breeze. Metaphor is an official incorruptible. It is also a metaphor for poverty. Nowadays, most people are compared to people who are honest and clean, strict with themselves and don't take bribes and pervert the law.
