In 392, after Zhai Liao's son and successor Zhai Zhao attacked Later Yan's border region, Murong Chui personally led an army against Zhai Zhao's capital Huatai (滑台, in modern Anyang, Henan). Zhai sought aid from Western Yan, but Murong Yong declined to send a relief force, and Murong Chui quickly crossed the Yellow River and captured Huatai, conquering Zhai's Wei state.
