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. In 368 as well, the key official Yue Wan, concerned about the growing corrupt practice by noble families of putting commoners into their fiefs—a practice that would mean that those commoners were only responsible to them, not responsible for paying taxes to the empire, leading to the empire's treasury being so lacking that it was unable to pay its officials—petitioned Murong Wei for a reform ending the practice. Murong Wei approved the reform and put Yue in charge of it, and Yue restored over 200,000 people to the tax-paying ranks. The nobles were all resentful of Yue, who died later in 368—and while most historians believed that he died of natural causes, having been already ill previously — the Book of Jin stated that he was poisoned by Murong Ping, who had much to lose from Yue's reform. In 369, the Jin general Huan Wen launched a major attack against Former Yan, defeating every army that Murong Ping sent against him, including the most major one commanded by Murong Zang, advancing to the vicinity of Yecheng, by now Former Yan's capital. In panic, Murong Ping and Murong Wei considered fleeing to the old capital Helong (和龍, in modern Jinzhou, Liaoning). Murong Chui, whose authority had been curtailed by Murong Ping previously, offered to make one last try to resist. Meanwhile, Murong Ping also sent messengers to Former Qin, requesting assistance—offering to cede to Former Qin the Luoyang region, which Murong Ke had captured in 365 if Former Qin would assist. Murong Chui, along with Murong De, were able to deal Huan a major defeat, and Former Qin forces soon arrived and dealt Huan another defeat. Huan would not be able to launch a major attack against Former Yan again. However, Murong Ping and Empress Dowager Kezuhun soon engaged in two damaging decisions. Still resentful of Murong Chui (whose wife was her sister but whom he did not favor), Empress Dowager Kezuhun denied him and his soldiers rewards
