《汉书·纪·景帝纪》
原先是官吏多有军功，车驾衣冠以轻便为主。所以特下此禁令。又担心酷吏断狱失于严酷，就向司法部门下达了减笞法、定瞷令。
先是，吏多军功，车、服尚轻，故为设禁，又惟酷吏奉宪失中，乃诏有司减笞法，定棰令。
As many officials used to have military achievements, their carriage and apparel were mainly simple. Therefore, this decree was made specifically. The emperor was also worried that cruel officials were too harsh in making judgments and sent out an order to reduce the application of corporal punishment and establish the order of punishment.
