Mandy was born in 1963 in Hong Kong. His father But Fan Chan is famous for his Chinese calligraphy. Mandy immigrated with his parents to Boston in 1976. His passion for martial arts started at the age of 12, when he was inspired by a Bruce Lee movie, Enter the Dragon. Growing up in the streets of Boston’s China Town, he took kung fu lessons and practiced his first kung-fu moves with his mentor like Donnie Yen 甄子丹 (currently he is the number one movie actor in Asia) and John S. (who is Hong Kong secretary of treasury). At school Mandy, as a part of Chinese culture classes, started to take Chinese dancing lessons and thus began his first on-stage experience, which inspired in him a passion for performing.
