Ruan Ji
The context goes on to say that after Sun Deng refused to talk with Ruan Ji, Xi Kang followed Sun Deng travelling for three years. Since Sima Zhao became generalissimo in 255, Holzman dates Ruan Ji's visit around 257, and Xi Kang's around 258 to 260. Based on the different mountain names, Chan says Ruan Ji visited Sun Deng twice, first around 226-230, and then around 255-263; and dates Xi Kang's travels at around 249–251.
