《汉书·传·谷永杜邺传》
古时候稻谷不丰收就减少饭食，灾祸屡屡发生就减少服饰，凶年不修建房屋，这是英明君王的制度啊。《诗经》中说： 百姓有悲伤的事，伏地爬行来赈救他们。 
古者谷不登亏膳，灾屡至损服，凶年不堲涂，明王之制也《诗》云： 凡民有丧，扶服救之。 
In ancient times, when the rice harvest was poor, people ate less; when disasters occurred repeatedly, they wore less clothing; and in bad years, they did not build houses. This was the system of wise kings. The Book of Poetry says: When the people are sorrowful, the king bows down to relieve them.
