《宋史·列传·卷九十五》
吕惠卿说 ：买米百万石，那么可节省东南之地的漕运费用，可用这些钱供给京师。 司马光说 ：东南地区发生钱荒而谷米散乱，如今不和籴粮米而取漕运钱，弃其有余，取其所无，农商都会受到伤害！ 侍讲吴申站起来说 ：司马光的话，是深切中肯之论。 
臣恐异日之青苗，亦犹是也。 帝曰： 坐仓籴米何如？ 坐者皆起，光曰： 不便。 惠卿曰： 籴米百万斛，则省东南之漕，以其钱供京师。 光曰： 东南钱荒而粒米狼戾，今不籴米而漕钱，弃其有余，取其所无，农末皆病矣！ 侍讲吴申起曰： 光言，至论也。 
Lü Huijing said: If we buy a million shi of rice, we can save the southeast's transportation costs, which can be used to supply the capital. Sima Guang said: The southeast is short of money and grain is scattered. Now, if we do not buy grain but take the transportation money, we will abandon surplus and take what we do not have, and both farmers and merchants will be harmed! Wu Shen, the attendant lecturer, stood up and said: Sima Guang's words are heartfelt and impartial.
