Huan Xuan
Qiao Zong was from Baxi Commandery (巴西, roughly modern Nanchong, Sichuan). By 405, he was a mid-level military commander under the command of Mao Qu (毛璩), the Jin governor of Yi Province (modern Sichuan and Chongqing). In 404, the warlord Huan Xuan had usurped the Jin throne from Emperor An, and Mao had, in response, mobilized his forces to ready to attack Huan Xuan, but Huan Xuan was quickly overthrown by Liu Yu, who restored Emperor An. However, Huan Xuan's nephew Huan Zhen (桓振) occupied the important city of Jiangling (江陵, in modern Jingzhou, Hubei) and continued to resist. Mao therefore continued to advance east, ready to attack Huan Zhen. He divided his forces into two groups, one commanded by his brothers Mao Jin (毛瑾) and Mao Yuan (毛瑗), and one commanded by Qiao Zong and Hou Hui (侯暉).
