In 556, Yuwen Tai, after entrusting his heir apparent and Yuwen Xian's older brother Yuwen Jue to Yuwen Xian's cousin Yuwen Hu, died. In spring 557, Yuwen Hu forced Emperor Gong of Western Wei to yield the throne to Yuwen Jue, ending Western Wei and establishing Northern Zhou. Yuwen Jue took the throne (as Emperor Xiaomin) with the alternative title of "Heavenly Prince" ("Tian Wang"), with Yuwen Hu serving as regent. Later that year, Yuwen Jue, trying to seize power from Yuwen Hu, had his plot discovered by Yuwen Hu, and Yuwen Hu deposed and then killed him, replacing him with another older brother of Yuwen Xian's, Yuwen Yu (as Emperor Ming). In 559, Emperor Ming, remembering Yuwen Tai's instruction, put Yuwen Xian in charge of the modern Sichuan and Chongqing region, with his headquarters at Yi Province (roughly modern Chengdu, Sichuan). Yuwen Xian, despite his young age of 15, was said to be a capable governor, paying attention to the people's concerns and to the important matters and making good decisions on legal cases. The people of the region favored him so much that they created monuments for him. Emperor Ming created him the greater title of Duke of Qi.
