Huan Wen headed north again in 356 with the hopes of capturing Luoyang. At the time, Luoyang was held by a Jin general turned rebel named Zhou Cheng (周成). Coincidentally, he was attacked by Yao Xiang who by then was an independent warlord himself. When Huan Wen reached Luoyang, he faced Yao Xiang at the Battle of Yi River in which Huan emerged victorious. Yao Xiang fled with his army while Zhou Cheng surrendered Luoyang and himself to Huan Wen. Jin held Luoyang for a decade, but would eventually lose it to Former Yan in 365.
