Guo Lu, who had surrendered to the Northern Wei Dynasty in Xuzhou, gathered a crowd to rebel, and many people responded. Li Chong sent Bu Jizhou from Gaoping to pretend to commit a crime and escaped to Guo Lu. Guo Lu took him in and let him do his work. After a few months, Bu Jizhou beheaded Guo Lu's head and sent it. The other thieves fled everywhere.
