《汉书·志·食货志上》
董仲舒劝说皇上道： 《春秋》不记载其他谷物，而麦和稻子没有成熟就加以记载，以此可见圣人对于五谷最重视麦与稻子。
董仲舒说上曰： 《春秋》它谷不书，至于麦禾不成则书之，以此见圣人于五谷最重麦与禾也。
Dong Zhong Shu advised the Emperor, in "Spring and Autumn" other grains are not recorded, but wheat and rice are recorded before they matured, this shows that the Saint values wheat and rice the most among all five grains.
