The "Taiwanese Opera" and the "Minnan Xiang Opera" are regarded as the twin sisters, which were interacting in the Japanese colonial period and the early postwar period. Communication between the two operas stopped naturally when military confrontation happened across the Taiwan Strait in 1949, so they developed in their own historical environment and social structure. Since the martial law was lifted in 1987, the Gezai operas across the Taiwan Strait have gradually communicated through the mass media, and the multi-way communication and conversation has slowly started in ecology of theatrical circles, operating strategy, creative thinking, performance space, histrionic landscape, and academic argument. In this paper, we carefully sort out the historical communicating records of the "contemporary" Gezai Operas between Taiwan and China mainland from the "secret contact" between 1949 and 1986, the "conversation expansion" between 1987 and 2000, to the "multi-way dialogue" between 2001 and 2012, and phenomena like reference or influence and feedback occurs accordingly through research approaches such as historical records of the press, works of the predecessors, interviews of the opera troupes, and observation of the performances.
