蜀汉政局与魏延之死

提及魏延之死，多数学者认为系杨仪奉诸葛亮之命，使马岱斩魏延。诚然，魏延之死与诸葛亮、杨仪以及马岱不无关系，然而杀魏延者，尚有费祎。虑及蜀汉国运的费祎，为确保自己能与蒋琬秉承诸葛亮生前的既定方针，顺利掌权蜀汉以求平稳发展，分别翦除对其乃至对蜀汉政局稳定构成威胁的魏延与杨仪。对手既已消亡，费祎终得与蒋琬先后奉行诸葛遗志，萧规曹随经营国家，使弱蜀仍得于三国乱世发展与自保达数十载。

The Political Situation of Shu and the Death of Wei Yan

When mentioned the death of Wei Yan,many scholars believe that Yang Yi obeyed the voice of Zhuge Liang, letting Ma Dai kill Wei Yan.It's true that Yang Yi,Zhuge Liang and Ma Dai are related to the death of Wei Yan,but Fei Yi was also one of the killers.As Fei Yi considered the future of Shu,in order to ensure the established long term policies of Zhuge Liang with Jiang Wan,and the steady development of Shu after getting the power,Fei Yi got rid of Wei and Yangyi, who would threaten him and the stability of the political situation of Shu,respectively.When opponents are eliminated, eventually Fei Yi inherited the commandment of Zhuge Liang with Jiang Wan and governed the state successively,thus weak Shu still can be developed and got self-hold in the turmoil of the Three Kingdoms period.This paper adopts the documentary analysis and transforms the perspective to analyze by literature research,in order to ratiocinate the relationship between Fei Yi and the death of Wei Yan step by step.
