《三国志·蜀书·刘彭廖李刘魏杨传》
刘备自立为汉中王，将治所迁到成都，需要一位得力将领镇守汉川，大家都认为一定是张飞，张飞心中也认为是自己。
先主为汉中王，迁治成都，当得重将以镇汉川，众论以为必在张飞，飞亦以心自许。
Liu Bei established himself as the King Of Hanzhong and moved his capital to Chengdu. He needed to find an able general to guard the Hanzhong region, and everyone believed that it would have to be Zhang Fei. Zhang Fei himself also believed that it would be him.
