郭贡 / Guo Gong (Late Han)
郭贡 / Guo Gong enters the wiki through Hanji 978 as the uncertain military actor whose arrival threatens 鄄城 during 曹操’s 兖州 crisis. The source says he brings several tens of thousands of soldiers, while rumor claims he may cooperate with 吕布 and 张邈.
His source role is not a long biography but a test of 荀彧’s judgment. Xun Yu reads Guo Gong as still undecided rather than already committed to Cao Cao’s enemies, meets him calmly outside the city, and causes him to suspect that Juancheng has more strength or preparation than it appears to have.
