徐溫
Over the years, Yan and other officials, including Chen Yanqian () and Xu Jie, had also advocated for Xu Wen to replace Xu Zhigao with a biological son, although the historical records did not indicate that they recommended Xu Zhixun specifically. Xu Zhixun himself had also lobbied Xu Wen, but Xu Wen responded, "None of you has much talent as your older brother." However, by 927, by which time Xu Zhixun carried the titles of commander of armed forces (行軍司馬, "Xingjun Sima"), military governor ("Jiedushi") of Zhongyi Circuit (忠義, headquartered in modern Xiangyang, Hubei, but which was then under control of Later Tang), and honorary chancellor (同中書門下平章事, "Tong Zhongshu Menxia Pingzhangshi"), Xu Wen changed his mind. He was planning to head to Guangling to recommend to then-King of Wu, Yang Pu, that Yang Pu claim imperial title, and then assign his two sons to new posts, with Xu Zhixun replacing Xu Zhigao as junior regent. However, as he was set to depart Sheng Prefecture, he became ill, and he instead wrote his petition and sent Xu Zhixun toward Guangling, intending to have Xu Zhixun replace Xu Zhigao after the petition were delivered. Xu Zhigao, hearing this, decided to resign and request to be the military governor of Zhennan Circuit (鎮南, headquartered in modern Nanchang, Jiangxi). However, when Xu Zhixun was still on the way, Xu Wen died, and Xu Zhixun, hearing of Xu Wen's death, immediately returned to Sheng Prefecture to attend to the aftermaths, allowing Xu Zhigao to, for the time being, remain as regent.
