慕容沖
Murong Hong was soon assassinated, however, and Murong Chong became the leader of the Xianbei rebels who would eventually be known as Western Yan. He put Chang'an under a siege and demanded that Fu Jiān deliver Murong Wei to him. Meanwhile, Murong Wei and his cousin Murong Su (慕容肅) organized the Xianbei men within Chang'an, preparing to start an uprising to join Murong Chong. In early 385, Murong Wei invited Fu Jiān to his house, under the pretense that his son was getting married, ready to assassinate Fu Jiān at the feast. Fu Jiān agreed to attend, but could not go due to rain, and news of the conspiracy leaked. Fu Jiān summoned Murong Wei and Murong Su to the palace. Murong Su suggested that they refuse and immediately start the uprising. Murong Wei refused, and both went to the palace. Fu Jiān questioned them about their conspiracy, and Murong Wei still tried to deny, but Murong Su, with proud words, admitted, and Fu Jiān executed them, as well as all remaining Xianbei people in the city.
