杜牧 / Du Mu
杜牧 / Du Mu enters the wiki through Hanji 168 part 2 as the later poet cited in the discussion of 项羽’s refusal to cross 乌江. The episode uses his Wujiang poem for the counterfactual that Jiangdong still had talented sons and that renewed struggle might have been possible if Xiang Yu endured shame and crossed.
The host does not fully accept the counterfactual. Du Mu’s line keeps open the strategic possibility of regrouping, but the episode argues that Xiang Yu’s deeper problem was his proud, emotional, low-reflection character. Even if he had crossed, the same failure to diagnose political and strategic causes might have led to the same endpoint.
