Niu Sengru
In 846, Emperor Wuzong died and was succeeded by his uncle Emperor Xuānzong. Emperor Xuānzong had long despised Li Deyu's hold on power, and soon thereafter Li Deyu was stripped of his chancellor position. Further, five chancellors whom Emperor Wuzong had exiled — Li Zongmin, Niu Sengru, Cui Gong, Yang Sifu, and Li Jue — were all soon ordered to be moved closer to the capital, with Li Zongmin ordered moved to Chen Prefecture (郴州, in modern Chenzhou, Hunan) to be the military advisor to its prefect, but it was said that Li Zongmin died before he could be moved.
