Murong Ping
Murong Ping, while apparently having military abilities, was incompetent and corrupt as a regent. In 368, when four of Former Qin's dukes rebelled against the Former Qin emperor Fu Jiān, they sought help from Former Yan. Many officials, including Murong Jun's brother Murong De the Prince of Fanyang, saw this as a perfect opportunity to conquer Former Qin, but Murong Ping declined to take any actions against Former Qin, so Former Qin forces crushed the four rebel dukes.
