The death of Cao Song, father of the famed warlord Cao Cao, remains one of the most debated and ambiguous episodes in late Eastern Han history.
In Romance of the Three Kingdoms, Cao Cao’s invasion of Xu Province(Xuzhou) is portrayed as a personal quest for vengeance—driven by the tragic murder of his father, Cao Song, and his entire family.
