《宋史·列传·卷一百五十二》
殿中侍御史刘光祖因为指责带御器械吴端，被改任太府少卿，彭龟年上疏乞求恢复他的职位，并写信给宰相说： 祖宗时曾改换官员的差遣及任职以增强台谏官的勇气，没有听说调换台谏官以维护宠臣私利的。 彭龟年兼任魏王府教授，升为国子监丞。
殿中侍御史刘光祖以论带御器械吴端，徙太府少卿，龟年上疏乞复其位，贻书宰相云： 祖宗尝改易差除以伸台谏之气，不闻改易台谏以伸幸臣之私。 兼魏王府教授，迁国子监丞。
Liu Guangzu, the palace attendant and commander, was demoted to the position of Minister of State Treasury for accusing Wu Duan of carrying royal weapons. Peng Guinian submitted a memorial asking for his reinstatement and wrote to the prime minister saying: “The ancestors had made changes to officials’ duties and appointments to strengthen the courage of censorial officials, but there had never been any demotion of remonstrating officials in order to preserve the favor of powerful ministers.” Peng Guinian concurrently served as professor of Wei王府 and was promoted to Minister of the Imperial College.
