Xinning grey fried pork liver originated in some rural areas of Xinning County. In the era of material shortage, villagers have been engaged in manual labor for a long time. Because malnutrition is easy to cause eye diseases, they will fry this dish at home. Old people eat clear fire to improve their eyesight, which has the effect of reducing fire and lowering blood pressure. Later, it was improved on the basis of tradition and introduced as a special dish.
