《宋书·本纪·卷二》
先前各州郡送来的秀才、孝廉，多是滥竽充数。刘裕上书天子，请求遵循旧制，用考试的办法加以甄别。
先是，诸州郡所遣秀才、孝廉，多非其人，公表天子，申明旧制，依旧策试。
Previously, most of the filial and incorruptible officials sent by the states and prefectures were pretenders. Liu Yu sent a memorial to the emperor, requesting to follow the old system and use examinations to differentiate them.
