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.
