In 912, the Wu (i.e., Hongnong, which was now referred to in historical accounts as Wu, as Yang Wo's brother and successor Yang Longyan, while initially carrying the title of Prince of Hongnong as well, later took on the title of Prince of Wu, which Yang Xingmi had carried at the time of his death) general Chen Zhang () attacked Yue Prefecture, capturing Wan, who was then the prefect of Yue. When Ma sent Yang Dingzhen () to try to recapture Yue, the Wu forces headed toward Jingnan instead. To prevent Ma from aiding Jingnan, the Wu general Liu Xin (), who governed Wei's old territory of Fǔ Prefecture and its surroundings, stationed himself at Ji Prefecture to pressure Ma. Subsequently, though, after Chen was unable to capture Jiangling, he withdrew. In 913, apparently in response, Yao, who carried the title of military governor of Ningyuan by that point despite Chu's loss of Ningyuan, attacked E Prefecture, but when the Wu general Lü Shizao () responded, Yao withdrew.
