There was a warlock in his service called Zhang Sheng, who claimed to be a master of divination. When Fan Yanguang was humble, he prophesied that he was destined to become a general or minister; once Fan Yanguang became eminent, he believed his words completely. He took him to live in the finest accommodations, wherever he was in command.
