Taiwan Bangzi originally came from Henan province in China. Within the evolution in Taiwan society, it reveals a strong tendency of localisation in the past ten years. This paper will examine three contemporary operas from three perspectives: content of scripts, stage-performing methods and music, in order to demonstrate the ongoing and strengthening process of localisation and crossover of Taiwan Bangzi in this decade. The intention and evidence of localisation in Taiwan Bangzi can be found through the analysis in this paper from three aspects and a comparison in figures and music examples.
