Xu Wen
Throughout the years, many of Xu's advisors, including Yan, Chen Yanqian (), and Xu Jie, had long advocated having Xu Wen replace Xu Zhigao as junior regent with one of his biological sons, and the oldest surviving among them, Xu Zhixun (younger), also had long requested to replace Xu Zhigao. Xu Wen did not have the heart to do so due to Xu Zhigao's diligence and filial piety. In 927, however, Xu Wen made up his mind to do so, so he prepared to head to Jiangdu (i.e., Yang Prefecture) to pay homage to Yang Pu and persuade Yang Pu to claim imperial title, and then carry out the replacement. As he was about to depart Jinling, however, he grew ill, so he wrote a petition urging Yang Pu to take imperial title and had the younger Xu Zhixun prepare to deliver it to Jiangdu, and then remain there to take Xu Zhigao's place. When Xu Zhigao heard this, he knew he could not resist his father, so drafted a petition asking to be made the military governor of Zhennan. However, before the younger Xu Zhixun could arrive at Jiangdu, Xu Wen died, forcing the younger Xu Zhixun to immediately return to Jinling, and Xu Zhigao remained as regent. Yang Pu posthumously created Xu Wen the Prince of Qi. After Xu Zhigao eventually seized the Wu throne and established Southern Tang, while he changed his name to Li Bian, he honored Xu Wen as Emperor Wu with the temple name of Yizu.
