This essay paper is about how 'relaxation' plays a special role. Unlike Stanislavsky system only takes it as a muscle relaxation, in Taiwan relaxation seems to mean a core value of acting. One of the reasons for this comes from Wu J. J.'s teaching, which is based on his psychology background and experience in the States. At that time people who worked in performing art looked for their own body language and training, in comparison with the western style. Therefore, the meaning of 'relaxation' comes to a spiritual resemblance. This paper is going to take the introduction to Tai-chi as an example to interpret the highlight of 'relaxation' and its special meanings in the acting training of Taiwan. Therefore 'relaxation' carries complicated meanings, so the performers in Taiwan have ambiguious understanding towards the idea of 'right now and right here' and 'why moves'.
