He joined the National Revolutionary Army and after the Communist victory moved to Taiwan.
He continued to work for the army, which assigned him to be an actor in educational films.
In 1956 the authorities asked him to join the government-owned Central Motion Picture Corporation (CMPC), where he started a career as a professional actor.
Miao was not particularly successful at CMPC and moved to the privately owned Union Film Company.
By the end of his career, he had starred in more than 100 such films and had become a recognizable name in the field.
