《新唐书·列传·卷七十四》
受灾的地方，缺乏的只是粮食，其他出产还有，贱卖粮食，买当地各种产品，利用人力，运到丰收地区，或者当地官府自己使用，国家开支不致缺乏；可以多支出粮食，让商人贩卖，分散进入村镇，贫穷的农户，不能上集市，辗转也能得到好处，自然免除了阻隔和饥饿，不需命令。
灾沴之乡，所乏粮耳，它产尚在，贱以出之，易其杂货，因人之力，转于丰处，或官自用，则国计不乏；多出菽粟，恣之粜运，散入村闾，下户力农，不能诣市，转相沾逮，自免阻饥，不待令驱。
In the affected areas, only grain was in shortage and other products were still available. Grain could be sold at low prices to purchase local products and utilize manpower to transport them to areas with bountiful harvests, or they could be used by local government for their own operations. In this way, the deficit in government expenditures could be avoided. Additional grain could be disbursed to allow merchants to sell it, distribute it to villages and towns, and allow poor farmers who could not go to markets to benefit from it indirectly, and thus naturally relieve the obstacles and hunger without the need for explicit instructions.
