Question: What is the cause of death of Fuquan, Prince Yu's father?
Sentence (from "Shunzhi Emperor"): Under his leadership, the Qing Empire conquered most of the territory of the fallen Ming dynasty (1368–1644), chased Ming loyalist regimes deep into the southwestern provinces, and established the basis of Qing rule over China despite highly unpopular policies such as the "hair cutting command" of 1645, which forced Qing subjects to shave their forehead and braid their remaining hair into a queue resembling that of the Manchus.
Relevant evidence: No
