The fifth-century historian Pei Songzhi, who annotated the "Sanguozhi", disagreed with Chen Shou's point of view. He argued that Jiang Wan and Fei Yi did well during their regencies when they refrained from making risky moves that could jeopardise Shu's future and when they successfully countered a Wei invasion and maintained peace within Shu's borders. He also pointed out that readers may find Chen Shou's concluding remarks confusing because Chen Shou did not provide any evidence to support his claim that Jiang Wan and Fei Yi did not put in their best to govern Shu and keep it safe.
