There is a charm written by the descendants of Chang T‘ien shih (張天師), of Lung hu shan (龍虎山) in Kiang-si; it is believed to be one of the most efficacious of charms for warding off demons and healing sickness.
There is also a charm written by Ling kuan (靈官). It is said that there are seventy-two idols bearing this name, all deified after the death of different individuals who, when living, had a reputation for driving out demons and warding off evil influences.
