《宋史·列传·卷一百五十七》
安丙杀杨巨源，杨辅恐怕有变乱，写信推举刘甲代替自己，韩胄怀疑杨辅怕事躲避，李壁说 ：孝宗听说吴瞞病了，立即下诏由汪应辰权宣抚使职事，蜀地赖以安定，这是先例。 于是任命刘甲为权宣抚使。
丙杀杨巨源，辅恐召变，以书举刘甲自代，侂胄疑辅避事，璧曰： 孝宗闻吴璘病，亟诏汪应辰权宣抚使职事，蜀赖以安，此故事也。 于是命甲权宣抚使。
When An Bing killed Yang Ju Yuan, Yang Fu was afraid there would be chaos and wrote a letter recommending Liu Jia as his replacement. Han Zhao suspected that Yang Fu was evading because he was afraid of trouble, and Li Bi said: "When Emperor Xiaozong heard that Wu Man was ill, he immediately issued an edict appointing Wang Ying Chen as Acting Minister of Appeasement, and the Sichuan region was stabilized as a result. This is a precedent." Liu Jia was appointed as Acting Minister of Appeasement.
