周叔 / Zhou Shu
周叔 / Zhou Shu enters the wiki through Hanji 155-2 as the Wei-side commander 韩信 asks about before attacking 魏豹. Han Xin’s concern implies that Zhou Shu would have made the campaign more difficult.
When Han Xin learns that Wei Bao has not used Zhou Shu, he treats the Wei command arrangement as weak. The source therefore uses Zhou Shu as an absent counterfactual: not a narrated battlefield actor, but the person whose non-selection exposes Wei Bao’s poor personnel judgment.
