Sima Fu
In the meantime, Chen Tai, Deng Ai, Sima Fu and other Wei officers led reinforcements to Didao to save Wang Jing. Chen Tai led his troops to the hills southeast of Didao, where they lit more fires and beat their war drums loudly to let the Wei forces in Didao know that reinforcements were on the way. As a result, the Wei forces in Didao experienced a surge in morale, and the Shu forces were taken by surprise. At the same time, Chen Tai also spread false news that they were planning to cut off the Shu army's retreat route. When Jiang Wei heard about it, he became fearful so on 11 November 255 he withdrew all the Shu forces and retreated to Zhongti (鐘堤; south of present-day Lintao County, Gansu).
