前秦
In 376, the Jin vassal, Former Liang, was attacked by Former Qin. Jin forces, under Huan Chong's command, attempted to relieve the pressure on Former Liang by attacking Former Qin, but Former Liang fell quickly and Huan Chong withdrew his forces. In apprehension of a Former Qin attack, Jin evacuated much of its population north of the Huai River to regions south of the river.
