《史记·八书·平准书》
天子很怜惜他们，下达诏令说： 江南一带火烧野草种田，水灌田地耕作，准许饥民到江淮一带就地取食谋生，想留在那里的人，可以在那里定居。 
天子怜之，诏曰： 江南火耕水耨，令饥民得流就食江淮间，欲留，留处。 
The emperor, feeling pity for them, issued an edict: "It is permitted for the hungry to go to the Jiang-Huai area to seek food and make a living, and those who wish to remain there may settle there."
