王延政
In 940, Wang Xi the Prince of Min was having a major dispute with his younger brother Wang Yanzheng the prefect of Jian Prefecture (建州, in modern Nanping, Fujian) that developed into a military conflict. Wang Xi sent an army to put Jian Prefecture under siege, and Wang Yanzheng sought aid from Wuyue. Despite the advice of the chancellor Lin Ding against such intervention on Wang Yanzheng's behalf, Qian Yuanguan nevertheless sent a 40,000-men army under Yang Renquan and Xue Wanzhong (薛萬忠) to aid Wang Yanzheng. By the time that they reached Jian Prefecture, Wang Yanzheng had already repelled Wang Xi's attack, and he sent the Wuyue army gifts, requesting that they withdraw. Yang and Xue refused and instead pitched camp near the city. In fear, Wang Yanzheng turned around and sought aid from Wang Xi. Wang Xi sent his nephew Wang Jiye (王繼業) to aid Wang Yanzheng and had his army cut off the food supply path of the Wuyue army. Wang Yanzheng then attacked the Wuyue army, defeating them, forcing Yang and Xue to flee. Later in the year, Emperor Gaozu gave Qian Yuanguan the greater titles of generalissimo of all armies (天下兵馬都元帥, "Tianxia Bingma Du Yuanshuai") as well as "Shangshu Ling" (尚書令).
