Wang Yanzheng
In 940, Wuyue's southern neighbor Min was in civil war, as its emperor Wang Yanxi (also known as Wang Xi) and Wang Yanxi's younger brother Wang Yanzheng the prefect of Jian Prefecture (建州, in modern Nanping, Fujian) were battling each other, and Wang Yanxi's generals Pan Shikui () and Wu Xingzhen () were putting Jian under siege. Wang Yanzheng sought aid from Qian Yuanguan. Despite advice by the chancellor Lin Ding against doing so, Qian Yuanguan launched an army commanded by Yang and Xue Wanzhong () to aid Wang Yanzheng. (At that time, Yang carried the title of military governor ("Jiedushi") of Ningguo Circuit (寧國, headquartered in modern Xuancheng, Anhui — an honorary title as Ningguo was then the territory of Wuyue's northern neighbor Wu) and chancellor (同中書門下平章事, "Tong Zhongshu Menxia Pingzhangshi").) Before they could arrive, however, Wang Yanzheng had already defeated Wang Yanxi's army himself and therefore asked the Wuyue army to withdraw, offering it gifts for doing so. Yang refused, and set up camp near Jian. Wang Yanzheng, in fear, turned to Wang Yanxi and asked "him" for aid. Wang Yanxi sent his nephew Wang Jiye () to aid Wang Yanzheng and also sent another army to cut off the Wuyue army's supply route. With torrential rains arriving and the food supply running low for the Wuyue army, Wang Yanzheng attacked it and defeated it, forcing Yang to withdraw.
