《资治通鉴·后唐纪·后唐纪二》
后唐帝下命令说： 按朝廷旧例，敕令不下发到各州，各州官吏也不能单独上奏。
敕： 朝廷故事，制敕不下支郡，牧守不专奏陈。
Emperor of Later Tang gave an order that stated: According to the old convention of the imperial court, imperial decrees should not be sent to the prefectures, and the local officials should not submit memorials independently.
