ZHANG GUOLAO (Chang Kuo Lao)
Known by his honorific as the Elder Zhang Guolao, this Immortal, like Lu Dongbin, is a master of alchemy, long a Taoist study, as well as a fabled necromancer able to “cross to the other side” and raise the dead.
He is often portrayed riding a white donkey, a mount he can transform into any size. He carries a curious object known as the pao pei, or fish-head drum, and long castanets, musical instruments that figure in his arcane rituals.
