Yuan Xi (onyomi: En Ki) was Yuan Shao's second son and Zhenji's first husband. Little is known about him, however due to his rather displeasing looks he was looked down upon by his father in comparison to his younger brother, Yuan Shang and his elder brother, Yuan Tan. After Cao Cao conquered Yuan Shang's territory, Yuan Xi, together with his younger brother fled to Liaodong to seek refuge. The ruler there, Gongsun Kang, instead had the two killed and sent their heads to Cao Cao.
