Chen Shou, the third-century historian who wrote Fei Yi's biography in the "Sanguozhi", praised Fei Yi for being compassionate, generous and charitable towards others. He gave credit to Fei Yi and Jiang Wan for following in Zhuge Liang's footsteps and pointed out that in doing so they managed to secure Shu's borders and maintain peace and harmony within Shu. However, he also criticised them for not putting in their best to govern a small state like Shu and keeping it safe.
