《金史·列传·卷四十七》
汉文帝继承秦、项战争的后果，四海困穷，天子不能具备同色的四匹马，就以敦朴示众，身穿黑粗丝织品，脚穿兽皮鞋，没多久天下富足安定，四方国家都臣服。
汉文帝承秦、项战争之后，四海困穷，天子不能具钧驷，乃示以敦朴，身衣弋绨，足履革舄，未几天下富安，四夷咸服。
Emperor Wen of Han inherited the aftermath of the wars between Qin and Xiang. The four seas were impoverished, and the emperor did not have enough horses of the same color to make up a team of four. He set an example of simplicity by wearing plain black silk and shoes made of animal hide. Soon, the empire became prosperous and stable, and all the neighboring states submitted to him.
