《资治通鉴·唐纪·唐纪五十三》
近些年来，免除正殿奏事，停止百官轮流奏事，谏官能够奉行的职责，只有在诏诰命令不尽合宜时，献上一本皂封缄的奏章而已。
近年以来，正牙不奏事，庶官罢巡对，谏官能举职者，独诰命有不便则上封事耳。
In recent years, the nullification of court reporting, the suspension of taking turns to report, the duties of the remonstrating official can be enforced, and only when the imperial edict is not appropriate, can a sealed奏章 be presented.
