《资治通鉴·汉纪·汉纪五十七》
益州四边地势险阻，中有沃野千里，是天府之地，而益州牧刘璋昏庸儒弱，北边还有张鲁相邻，虽然百姓富庶，官府财力充足，却不知道珍惜，智士贤才都希望有一个圣明的君主。
益州险塞，沃野千里，天府之土；刘璋暗弱，张鲁在北，民殷国富而不知存恤，智能之士思得明君。
Yi prefecture has dangerous topography on all four sides, with thousands of fertile fields in the middle, and is a land of abundance; and the governor of Yi Liu Zhang is muddleheaded and weak, the north still adjacent to Zhang Lu; although the common people are wealthy and the government has sufficient finances, he does not cherish them, and wise and worthy talents all hope for a sagacious ruler.
