Li Fengji
As Li Yan was chronically ill and Li Fengji tended to him, Li Fengji studied the medical books of the time and became knowledgeable in medicine. After Li Fengji passed the imperial examinations, the general Fan Xichao (范希朝) invited him to serve as a scribe on his staff when Fan served as the military governor ("Jiedushi") of Zhenwu Circuit (振武, headquartered in modern Hohhot, Inner Mongolia). Fan subsequently recommended Li Fengji to then-reigning Emperor Dezong (Emperor Suzong's grandson), and Li Fengji was made a "Zuo Shiyi" (左拾遺), a low-level consultant at the examination bureau of government (門下省, "Menxia Sheng"). He was later promoted to "Zuo Bujue" (左補闕), also consultant at the examination bureau, and then made an imperial censor with the title "Shiyushi" (侍御史). He later served as the deputy emissary on a mission to Tufan.
