《孔子家语·屈节解》
齐国人进攻鲁国，取道单父，单父一些德高望重的人请求说： 麦子已经熟了，现今齐国就要到来，人们来不及收自己家的麦子，请放民出城，让百姓都去收城部附近的麦子。
齐人攻鲁，道由单父，单父之老请曰： 麦已熟矣，今齐寇至，不及人人自收其麦，请放民出，皆获传郭之麦，可以益粮，且不资于寇。 
The people of Qi attacked Lu and took the road through Danfu. Some of the highly respected people in Danfu asked, "The wheat is ripe, and the people of Qi are coming now. The people will not have time to harvest their own wheat. Please let the people out of the city and let them all go to harvest the wheat near the city."
