Juqu Mengxun
In 417, Juqu Mengxun tried to lay a trap for Li Xin (who had succeeded Li Gao after Li Gao's death that year) by having his general Juqu Guangzong (沮渠廣宗) pretending to surrender to Western Liang, while Juqu Mengxun lay in wait. However, Li Xin realized the trap and withdrew, and as Juqu Mengxun gave chase, Li Xin defeated him.
