That year, Juqu Mengxun became fearful and angry when he heard that the Jin general Liu Yu had destroyed Later Qin and seized its territory, probably in fear that Liu Yu would next advance against his state. When his official Liu Xiang (劉祥) was making a report to him with a smile, Juqu Mengxun angrily stated, "How do you dare to smile upon hearing that Liu Yu had entered Hangu Pass!" and beheaded Liu Xiang. (This is despite Juqu Mengxun having made an overture in 415 agreeing to submit to Jin as a vassal.) His fears appeared to subside after Liu Yu left former Later Qin territory late in 417, and dissipate completely when the Xia emperor Helian Bobo crushed troops under Liu Yu's son Liu Yizhen (劉義真) in 418.
