In the fifth year of Kaibao, his son Xu Yong was dismissed from his post as magistrate of Luxian County. Xu Yong went to the court to play music and said: I am 75 years old this year, my father Xu Qiong is 99 years old, my elder brother is 81 years old, and my second brother is 79 years old. I want to ask for an official position in a nearby place so that I can go home to serve my father and brother.
