A foreign Henan Opera has survived, changed, and localised and established its Taiwan identity from Henan Opera to Taiwan Bangzi for more than sixty years in Taiwan, since it was introduced from China to Taiwan under a historical occasion. This paper examines the localising process from Henan Opera to Taiwan Bangzi in Taiwan from four perspectives: social and cultural background, performers, contents of scripts, and textures of music. The time frame is divided into two periods (1947-1987 and 1987-2013) to discuss the processes separately.
