Li Gao
Princess Dowager Yin (尹太后, personal name unknown) was a princess dowager of the Chinese state Western Liáng. She was the mother of its second duke, Li Xin and the second wife of its founder Li Gao (Prince Wuzhao), who was posthumously honored by Li Xin as a prince, and therefore Lady Yin was honored as a princess dowager even though her husband never carried the princely title while alive.
