From Guanzi herders written by Guan Zhong in the Spring and Autumn Period.

Cang Li Man knows manners. The next sentence is: Only when you have enough food and clothing can you know the honor and disgrace, which comes from Guanzi Herdsmen written by Guan Zhong in the Spring and Autumn Period. Only when people have enough granaries and plenty of food and clothing can they pay attention to etiquette and honor and disgrace. Origin: The granary knows etiquette, food and clothing know honor and disgrace "comes from Guan Zhong who helped Qi Huangong become the first overlord in the Spring and Autumn Period.

In the original text of Guanzi Herdsmen, "granary actually knows etiquette, food and clothing know honor and disgrace". Sima Qian, a historian of the Western Han Dynasty, quoted a sentence from Historical Records and Biographies of Yan Guan: "Ze" was changed to "Er", and there is a saying that "etiquette is known in the warehouse, and honor and disgrace are known in food and clothing".

At present, it is generally believed that "the granary knows etiquette, food and clothing know honor and disgrace" comes from Biography of Historical Records Yan Guan: "The granary knows etiquette, food and clothing know honor and disgrace, and clothes are solid. If the four dimensions don't open, the country will die. Ordering food is like running water, making it popular. " Interpretation is: when the granary is full, you will know the etiquette; Eat and wear warm clothes, and you will know the honor and disgrace; The enjoyment of kings has a certain system, and the six relatives are closely linked; If the ethics of propriety, justice and shame are not publicized, the country will perish. Promulgating laws is like flowing water from the source, and it must conform to the people's hearts.
