Murong Xi
After Murong Xi left Longcheng, Feng Ba and his brother Feng Sufu (馮素弗), who had hidden themselves since Murong Xi had previously wanted to have them executed, conspired with their cousin Feng Wani (馮萬泥) to start a rebellion. They did so with the help with the general Zhang Xing (張興) and those who had previously conspired with the general Fu Jin (苻進) in a failed coup attempt earlier that year. Because Feng Ba was friendly with Murong Yun, he persuaded Murong Yun to become their leader, and they quickly captured the palace and closed the city gates. Murong Yun was declared the Heavenly Prince.
