Chai Jin
Yan Qing makes many contributions, chief of which is the sabotage on the rebel force of Fang La after infiltrating it with Chai Jin, who insinuated himself into Fang's confidence disguised as a businessman. As the surviving heroes return to Dongjing for rewards, Yan Qing senses that hostile forces in the court would cause them harm. He slips away one night amid the return trip, leaving a poem for Song Jiang saying that he does not covet glory. Legend has it that he finds Li Shishi and they live together in anonymity for the rest of their lives.
