The Tea-Picking opera of Taiwan is stable among the people and has improved for about a hundred years, from the original Three Characters Tea-Picking Opera to more contemporary pieces. Nowadays, this performing art's artistic connotation is different and better than it was. Throughout the evolutionary process of the Tea-Picking Opera, the "Three Characters Tea-Picking Opera", the "civil and martial pieces in the theater times" and the maturing "Hakka Opera", we can tell the phenomenon of the mixing and coexistence. Besides, whether it is the outdoor thank God drama, modern play in the theater or made for TV media, all of them appear to be known as "Hakka Opera" today, and contain the feature of being multi-artistic. The Tea-Picking Opera is a new type of drama. In recent twenty to thirty years, its artists have been trying to apply more themes and ways to prosper the script and performance, including the culture-crossing (drama-crossing) and the intention altune-crossing and language-crossing. All these new explorations have become the growing power of the Taiwanese Tea-Picking Opera, proving not only that the drama is still in the position of growing and developing, but also that the play of the works from the writers and actors have become the main structure of modern Tea-Picking Opera. This article is entitled "Learn From the History of Tea-Picking Opera: Take the Re-staged Process of "the Big and Small Section" (Marry the Foreign) as an Example." I use the "(Marry the Foreign) the fifth tune" as the origin of the discussion to explore the possibility of learning from the traditional repertory, and then to link the modern script and the traditional ones together. I produce the theory that the Tea-Picking Opera has already built its art-territory and possibility during the process of the exploration.
