Juqu Mujian
Li Jingshou was the daughter of the Western Liang prince Li Gao and Lady Yin, who was later princess dowager when Li Jingshou's brother Li Xin became prince in 417. When he was subsequently defeated and killed in 420 by the Northern Liang prince Juqu Mengxun, the Western Liang capital Jiuquan (酒泉, in modern Jiuquan, Gansu) fell to Northern Liang, and Princess Dowager Yin and Li Jingshou were captured. However, because Juqu Mengxun admired Princess Dowager Yin's courage (in refusing to plead for her life), he treated her with respect, and married Li Jingshou to his son Juqu Mujian.
