《汉书·传·贾谊传》
所以那些处于应被大声谴责呵斥的地位的人，听到谴责呵斥就穿上丧服，盘水加剑，到请罪的房间去请罪，皇上不叫人捆绑起来牵着走。
故其在大谴大何之域者，闻谴何则白冠氂缨，盘水加剑，造请室而请罪耳，上不执缚系引而行也。
Therefore, those who were in a position to be loudly condemned and reprimanded, would put on funeral clothes, carry water and swords, and go to the room of confession to plead guilty. The emperor would not allow people to tie them up and lead them away.
