西秦
In 428, when Qifu Chipan died and was succeeded by Qifu Mumo, Juqu Mengxun made a major attack on Western Qin. Qifu Mumo sent back his general Juqu Chengdu (沮渠成都), whom Qifu Chipan captured in 422, to seek peace, and they entered into a peace agreement. However, just several months later, Juqu Mengxun renewed his attacks on Western Qin.
