Juqu Mengxun
Li Xin was defeated and killed by Juqu Mengxun, and Western Liang's capital Jiuquan (酒泉, in modern Jiuquan, Gansu) fell. Princess Dowager Yin was captured, but she maintained her dignity and did not plead with Juqu Mengxun for her life or mourn her son's death. Juqu Mengxun praised her and had his son Juqu Mujian marry her daughter Li Jingshou.
