The purpose of this study is to explore traditional culture and history thinking based on American theorist Richard Schechner's environmental theatre. The performance of Gua utilizes general and specific definition of environmental theatre, Chinese myth and history stories and the performance theories of Tai-Chi and Tai-Ko to integrate eastern traditional culture with eastern performance theories. The aim of Gua is to make the theatre artists to discover the value and meaning of tradition and culture and then to deliver traditional value and meaning to theatre audience throughout the Gua production. Based on the concepts of Tai-Chi and the Five Elements, Gua was intended to expand the general education of integrated eastern and western cultures through the format of environmental theatre and the performance training of Tai-Chi and Tai-Ko. There are three parts. The first part is the definition and format of environmental theatre, the second is the traditional culture and hi story thinking of Gua, and the third part is the performance theories and meaning of Gua.
