Question: Who is Sima You's paternal grandfather?
Sentence (from "Sima Zhao"): Towards the end of the campaign, he had himself created the Duke of Jin and accepted the Nine bestowments—a step that put him closer to usurpation of the throne—although he never actually ascended the throne, having further styled himself the King of Jin in 264, and then died in 265.
