鲜卑 / Xianbei
鲜卑 / Xianbei enters the wiki through Hanji 998 as a northern cavalry group joining the anti-公孙瓒 coalition. The episode says several thousand Xianbei riders follow 鲜于辅 south, help welcome 刘和, and coordinate with 乌桓 and 袁绍’s side.
The source uses Xianbei mainly to show that Gongsun Zan’s political failure has widened beyond a narrow Han official dispute. Frontier groups, Liu Yu loyalists, and Yuan Shao’s network all find common cause against him.
