公孫淵
Having inflicted a disgrace on the imperial armies, Gongsun Yuan had gone too far to turn back. In a series of contradictory actions that bear the hallmark of panic, Gongsun Yuan memorialised the Wei court in hope of getting a pardon on one hand, while formally declaring independence on the other by assuming the title King of Yan. He also assigned an era name for his reign, Shaohan (), meaning "Succeeding Han". This was problematic for his peace efforts for two reasons: first, proclaiming era names was a practice usually reserved for emperors, showing his intention to claim the imperial position; secondly, the era name itself implied that Wei's succession of the Han dynasty was somehow illegitimate. As king, he tried to entice the Xianbei into attacking Cao Wei by conferring the rank of chanyu to one of its chiefs, but the Xianbei had not recovered from the death of Kebineng: the chieftains were too preoccupied with internal disputes to launch a large-scale attack on Wei.
