Guo Si
Taking advantage of the chaos and massive confusion caused by the civil war between Li Jue and Guo Si, Emperor Xian sneaked out of Chang'an and was rescued by the leader of the White Wave Bandits, Yang Feng. Yang Feng, along with Dong Cheng, Yang Ding and Xu Huang, defeated Guo Si, who had led his troops in pursuit of the emperor. Guo Si returned to Li Jue to make a last-ditch effort to recapture Emperor Xian. Li Jue and Guo Si gained initial success by defeating Yang Ding, but were driven back by Yang Feng and Dong Cheng. Since then, Guo Si returned to Mei County and never took further action to retrieve the emperor, while Li Jue occupied Chang'an.
