Guo Si
After Dong Zhuo was assassinated in Chang'an in 192, Fan Chou joined a group of Dong Zhuo's followers, led by Li Jue and Guo Si, and seized back control of Chang'an from Wang Yun and Lü Bu. Li Jue and Guo Si then controlled the Han central government and Emperor Xian in the same way Dong Zhuo did. Around this time, they promoted Fan Chou to the rank of a General of the Household (中郎將).
