公孙瓒
The "Yingxiong Ji" (英雄記) recorded that Zou Jing once served alongside Gongsun Zan in a battle against barbarians. Once, Zou Jing fell into a trap and was besieged by the barbarians. Gongsun Zan led his troops to attack the barbarians and lifted the siege. Both of them then led their men to attack the barbarians as they were retreating and succeeded in driving them away from the northern border.
