Guo Si
After Dong Zhuo was assassinated in Chang'an in 192, Li Jue, Guo Si, Zhang Ji and other former followers of Dong Zhuo requested amnesty from Wang Yun, who replaced Dong Zhuo as the new head of the central government. However, Wang Yun refused and wanted to have all of them executed. Heeding Jia Xu's advice, Li Jue, Guo Si, Zhang Ji and Dong Zhuo's former followers led their troops to attack Chang'an and succeeded in driving away Lü Bu and seizing control of the central government. Zhang Ji was then appointed as General Who Guards the East () and ordered to station at a military garrison in Hongnong Commandery (). He was also enfeoffed as the Marquis of Pingyang ().
