"In the years before Emperor Qianwu of the Great Zhou dynasty ascended to the throne, my ancestors from the Su Family had already been serving by his side. Emperor Qianwu was brave and good at fighting, and he was surrounded by talented people. Back then, a Taoist with the surname Wang and the given name Xu, who had great skills and was capable of devising strategies without omission, was the one Emperor Qianwu trusted and relied on the most."
