《宋史·列传·卷一百四十八》
李椿统计大农每年需米一百七十万斛，而省仓观有米仅够一二个月的支用，就感叹地说： 这真是所谓的国将不国了。 于是竭力请求每年储备二百万斛粮食作为一年的储蓄。
椿会大农岁用米百七十万斛，而省仓见米仅支一二月，叹曰： 真所谓国非其国矣。 力请岁储二百万斛为一年之蓄。
Li Chun calculated that the Ministry of Agriculture needed 1.7 million bushels of rice each year, but the provincial granaries only had enough rice to last for one or two months. He sighed and said, “This is truly what is meant by a country that is about to collapse.” He therefore made every effort to store two million bushels of grain each year for a one-year reserve.
