《农桑辑要·典训·经史法言》
《管子》： 百姓没有不劳而食的门路，必然会务农；百姓务农，田地便会开垦；田地开垦，粮食就会增多；粮食多，国家就会富足。 
《管子》： 民无所游食，则必农；民事农，则田垦；田垦，则粟多；粟多，则国富。 
The Guanzi: The common people have no way to get food without working. They will inevitably work on farming. The common people work on farming, and then the farmland will be reclaimed. When the farmland is reclaimed, there will be more food. When there is more food, the country will be rich.
