Fuzhou, Jiangxi
Li Decheng was later made the military governor of Weiwu Circuit (威武, somewhat of an honorary title, as Weiwu was traditionally headquartered in modern Fuzhou, Fujian, then under the control of Wu's southeastern neighbor Min) and put in charge of Fu Prefecture (撫州, in modern Fuzhou, Jiangxi — not the same Fuzhou as Weiwu's traditional headquarter site). While he was at Fu, there was an occasion when the arrogant junior regent Xu Zhixun (Xu Wen's oldest biological son), hearing that Li had many singing girls in his household, demanded that Li give some to him. When Li responded that these singing girls were too old for Xu and that he would try to find younger and more beautiful ones for Xu, Xu responded to Li's messenger, "One day I will kill Li Decheng and take even his wife!" (However, this threat was never carried out, as Xu Zhixun himself was thereafter assassinated by the general Zhu Jin and replaced by his far more civil adoptive brother Xu Zhigao.) At some point (unclear when), another marital connection was made between the two families, as one of Li's daughters married Xu Zhigao's son Xu Jingda.
