《旧唐书·列传·卷四十二》
娑葛知道了此情大怒，举兵入侵，造成严重的边患。在这种情况下，监察御史崔琬劾奏宗楚客等。按原有的制度，大臣中有被御史弹劾的，就要低头弯腰站在朝堂待罪。
旧制，大臣有被御史对仗劾弹者，即俯偻趋出，立于朝堂待罪。
Shege was furious when he learned about this, raised troops to invade, and caused serious border troubles. Under such circumstances, the Supervisory Official Censor Cui Wan impeached Zong Chukuo and others. According to the original system, if a minister was impeached by the censor, he would have to bow his head and bend over and stand in the court to be convicted.
