After Juqu Mujian succeeded Juqu Mengxun in 433, Lady Li became princess, but in 437, Juqu Mujian was forced to divorce her and marry Northern Wei's Princess Wuwei, sister to Northern Wei's Emperor Taiwu. Princess Li died soon thereafter, and after Princess Li's death, Princess Dowager Yin had been sent to live in Jiuquan. Before the commander of the garrison there, she feigned disinterest in going to Yiwu (伊吾, in modern Hami Prefecture, Xinjiang), where some of her grandsons had fled. When the guard around her relaxed, she secretly fled and she lived out her years in Yiwu, dying at the age of 74.
