Taoist Tai Chi is an exercise form of t'ai chi ch'uan which is taught in more than 25 countries by the non-profit  International Taoist Tai Chi Society and associated national Taoist Tai Chi societies. It is a modified form of Yang-style t'ai chi ch'uan developed by Taoist monk Moy Lin-shin in Toronto, Canada. Moy incorporated principles of Lok Hup Ba Fa and other internal arts to increase the health benefits of practising the form.
