Fuzhou, Jiangxi
As of 909, Xu was also carrying the title of deputy commander of the Huainan army (行軍副使, "Xingjun Fushi") when he, believing that Jinling was a key location to control the Yangtze River with a fleet, gave himself the additional title of prefect of Sheng Prefecture (昇州, i.e., Jinling) but sent Xu Zhigao there to actually take command of the fleet there. Later that year, when Wei Quanfeng the prefect of Fu Prefecture (撫州, in modern Fuzhou, Jiangxi), who had nominally submitted to both Hongnong and Later Liang, rose against Hongnong and claimed the title of military governor of Zhennan, Xu, at Yan's recommendation, sent Zhou Ben against Wei. Subsequently, Zhou defeated and captured Wei, allowing Hongnong to take Fu Prefecture under actual control.
