In 918, Liu Xin put Qian Prefecture (虔州, in modern Ganzhou, Jiangxi), which was then ruled by the warlord Tan Quanbo, whose territory was wedged between Wu, Chu, and the territories of the Later Liang vassals Liu Yan and Wang Shenzhi the Prince of Min, under siege. Tan sought aid from three states which were Later Liang vassals — Wuyue, Min, and Chu. In response, Wuyue's prince Qian Liu sent his son Qian Chuanqiu () to attack Wu's Xin Prefecture (信州, in modern Shangrao, Jiangxi); Ma sent his officer Zhang Keqiu () to advance to Gutting (古亭, in modern Ganzhou); and Wang sent an army to advance to Yudu (雩都, in modern Ganzhou), all seeking to aid Tan. The Wuyue forces, however, were repelled by Xin's prefect Zhou Ben. Subsequently, Liu sent part of his army to repel the Chu army. When the Wuyue and Min forces heard that the Chu army had been repelled, they withdrew, leaving Tan without external aid.
