《资治通鉴·晋纪·晋纪十八》
李寿于是伪造妹夫任调来信。说李期将要攻取李寿，李寿的部众信以为真。李寿于是率领步、骑兵一万多人由涪地出发，偷袭成都，并许愿用城中财物作为对部众的奖赏。让部将李奕充任前锋。
寿乃诈为妹夫任调书，云期当取寿；其众信之，遂帅步骑万馀人自涪袭成都，许赏以城中财物，以其将李弈为前锋。
Li Shou then forged a letter from his brother-in-law Ren Tiao, saying that Li Qi was planning to attack Li Shou, and Li Shou's followers believed it. Li Shou then led more than 10,000 infantry and cavalry troops from Fudi to attack Chengdu by surprise, promising to reward them with the wealth of the city. He put his subordinate general Li Yi in charge of the vanguard.
