In 951, Guo Wei and his nephew-in-law Chai Rong were station at Weizhou (魏州; today's Linzhang County, Hebei) when the Later Han emperor Liu Chengyou killed their entire families left behind in the capital Bianzhou (汴州; today's Kaifeng, Henan). Guo led his troops to attack the capital, and after the death of Liu Chengyou, declared himself the emperor of the new Later Zhou.
