Guo Si
At the time, Guo Si's jealous wife became suspicious that her husband was having an affair with one of Li Jue's concubines so she decided to prevent her husband from attending Li Jue's banquets. She poisoned the gifts of food that Li Jue had given to them and convinced her husband that he should not be so trusting of Li Jue. Later, Guo Si became very drunk at another one of Li Jue's banquets and suddenly convinced himself that he was poisoned. He ingested liquid feces to force himself to vomit, which greatly offended Li Jue and drove the two leaders to battle. The situation ended up with Li Jue kidnapping Emperor Xian and Guo Si kidnapping the emperor's ministers.
