慕容垂
In 378, Murong Chui participated in the campaign commanded by Fu Jiān's son Fu Pi against Jin's key city of Xiangyang. In 382, when Fu Jiān wanted to launch a major campaign to destroy Jin and unite China, most officials, including Fu Jiān's brother Fu Rong, who succeeded Wang as prime minister after Wang's death in 375, opposed, but Murong Chui and Yao Chang urged the campaign, and Fu Jiān launched his campaign in fall 383. However, Former Qin forces, commanded by Fu Rong, was defeated by Jin forces at the Battle of Fei River despite great numerical superiority; Fu Rong was killed, and almost the entire army collapsed—although the forces under Murong Chui's command remained intact, and Fu Jiān, who suffered an arrow wound during the defeat, fled to Murong Chui. Murong Chui's son Murong Bao and brother Murong De both tried to persuade Murong Chui to kill Fu Jiān while he had the power to, but Murong Chui instead returned his forces to Fu Jiān's command and returned to Luoyang with Fu Jiān. However, under suggestion by his son Murong Nong, he planned a rebellion to rebuild Yan.
