In 367, Murong Ke grew ill. He tried to persuade Murong Ping, Murong Wei, and Murong Wei's older brother Murong Zang (慕容臧) the Prince of Le'an that one of his main responsibilities, as the commander of the armies, should be transferred to Murong Chui the Prince of Wu, his brother, as he saw Murong Chui as a capable general, but after Murong Ke died later that year, Murong Ping declined to do so, and instead gave that post to Murong Wei's younger brother Murong Chong the Prince of Zhongshan. Murong Ping himself assumed the regency and held power in conjunction with Empress Dowager Kezuhun.
