徐溫
The first historical reference to Xu Zhixun was in 918, when the elder Xu Zhixun, then serving as the junior regent at Wu's capital Guangling (廣陵, in modern Yangzhou, Jiangsu) with Xu Wen stationed at Sheng Prefecture (昇州, in modern Nanjing, Jiangsu), was assassinated by the general Zhu Jin, who then committed suicide. All of Xu Wen's sons, except Xu Zhigao, who was then 30, were then said to be young, so Xu Wen made Xu Zhigao the junior regent, replacing the elder Xu Zhixun. Subsequently, Xu's entrusted official Yan Keqiu suggested replacing Xu Zhigao with Xu Zhixun, but Xu Wen did not do so.
