永明中，會稽鍾山有人姓蔡，不知名。山中養鼠數十頭，呼來即來，遣去便去。言語狂易，時謂之「謫仙」。不知所終。
During the Age of Eternal Brilliance (483-493 CE), on Mt. Zhong in Guiji there was a man whose family name was Cai. His given name is unknown. In the mountains he raised several dozen rats. He would call them forward and they would come forward, he would send them away and they would go away. In speech he was deranged. The people of the day called him a ‘Banished Immortal.’ No one knows what happened to him in the end.
