《资治通鉴·宋纪·宋纪十》
到了这时，即使是年长的皇子去藩镇地方担任首领，或者是出身贫民的官员去地方镇守，典签也都独揽大局，接受官员们的报告，传达朝廷的命令，把持着重要的权力，刺史不能独自去行使权力。

By this time, even if it was an older prince who went to a fiefdom to serve as a leader, or an official from a poor background who went to a local town to guard it, the assistant secretary would still monopolize the overall situation, receive reports from officials, and convey imperial edicts. They held important powers, and the prefects could not exercise power independently.
