Hou Jing
It is not known when Hou Jing was born, but it was known that he was from Huaishuo Garrison (懷朔鎮) -- one of the garrisons that Northern Wei established on the northern border to defend against Rouran attacks. He appeared to be ethnically Chinese, but the matter of his ethnicity is not conclusive. When he was young, he was one of a group of friends who associated with Gao Huan, who often spent time in the countryside, seeking to correct injustice.
