Chairman Mao's "Qinyuanchun." The seventh, eighth and ninth sentences at the end of "Changsha": "To point out the country and inspire the words, the dung soil was used by thousands of households." The word "dung soil" is a noun used as a verb. Chairman Mao regarded the marquis of ten thousand households as less than dirt. This was his revolutionary spirit of contempt for class enemies. The word "dung soil" is not only used appropriately, but also used concisely.
