Guo Si
Lü Bu fled to Henei Commandery to join Zhang Yang after his escape. Yuan Shao sent his men to pursue Lü Bu but they were afraid of Lü and did not dare to approach him. Zhang Yang and his subordinates were bribed by Li Jue and Guo Si to kill Lü Bu. When Lü Bu heard about it, he told Zhang Yang, "I'm from the same province as you. If you kill me, you'll become weaker. If you recruit me, you can obtain the same honours and titles as Li Jue and Guo Si." Zhang Yang pretended to agree to help Li Jue and Guo Si kill Lü Bu but he secretly offered refuge to Lü instead. When Li Jue and Guo Si learnt that Zhang Yang had accepted Lü Bu, they became worried so they sent an imperial decree to Henei in Emperor Xian's name, appointing Lü Bu as the Administrator (太守) of Yingchuan Commandery.
