In 918, Wu, which was then ruled by Yang Wo's brother and successor Yang Longyan, launched a major attack, commanded by the general Liu Xin (), on Tan Quanbo the military governor of Baisheng Circuit (百勝, headquartered in modern Ganzhou, Jiangxi), who was ruling the circuit in independence but whose nominal allegiance had vacillated between Wu and Later Liang. Tan sought aid from Min, as well as Wuyue and Chu. Min forces advanced to Yudu (雩都, in modern Ganzhou) to try to aid Tan, while Wuyue and Chu also sent troops. After Liu then defeated Chu troops, Min and Wuyue forces also withdrew. Subsequently, Liu captured Tan's capital Qian Prefecture (), allowing Wu to directly take over Baisheng Circuit.
