Sima Yu
Xi Zuochi's relationship with his employer became strained after a visit to the capital city, where he met Sima Yu, future Emperor Jianwen of Jin and political rival of Huan Wen. Xi Zuochi was apparently so taken with Sima Yu that Huan Wen felt it best to distance himself from Xi Zuochi, and demoted him to Grand Administrator of Hengyang, in the Xiang river basin far to the south, in present-day Hunan. Xi Zuochi may have suffered a stroke at this time, contributing to his difficulty walking later in life.
