《三国志·蜀书·刘彭廖李刘魏杨传》
臣往北出兵，想要得到李平的部队相助，以镇守汉中，李平再三推辞，没有前来汉中的想法，反而把五个郡连起来自己做巴州刺史。
臣当北出，欲得平兵以镇汉中，平穷难纵横，无有来意，而求以五郡为巴州刺史。
"When your subject was headed north to engage the enemy, he wished to secure Li Ping's assistance in guarding Hanzhong; but Li Ping repeatedly declined and showed no willingness to come to Hanzhong; instead, he joined together five counties and established himself as Governor of Bazhou."
