In ancient China the whole empire was an agricultural community, so that the grain was not only the subject of production and consumption, but also the means of exchange and distribution (equivalent of money). Government lending of grain was practiced during the Chou dynasty to prevent usury. Besides, during Sui dynasty, the government introduced the system of village granary to store grain against bad years, which embodied the principle of "taking away the surplus to fill the insufficiency". It was carried on and improved through Tang dynasty.
