Museums provide the encounter fields for different cultures and play important roles in comprehending the communications of inter-regional cultures. The narrative space in museums often implies many potential growth paths of diverse ethnic cultures. If the museum was though of as the audience thinking about its own existing space, then exhibitions could be the mechanism of encoding cultures, and the audience could be the decoders for understanding. This article is aimed to explore the significance of local Taiwan visitors' responses to three Oceania related exhibitions of National Museum of Natural Science (NMNS), Taichung, Taiwan. These exhibitions are the ”Vaka Moana: Voyages of the Ancestors”, ”Cape Impressions: Journey to New Guinea by Max and Nin-sheng Liu” and ”Oceania Gallery”, thus highlighting the patterns of the reconstructed Oceania culture in NMNS. Through both quantitative analyses of demographic characteristics and qualitative approaches of written messages, interview feedbacks, and observations, etc, this paper attempts to group together the networking, interleaving dialogs between the museum and the visitors, and then discuss the dynamic relationship between cultural objects, performances, and peoples, thereby expressing the significance of cross-cultural differences and meaning spatially and temporally. Numerous written and oral responses from visitors indicate that the material cultures of the Pacific Islands is not only a kind of aesthetic artworks, but also a symbol of carrier experienced countless time and space alternatively. In other words, the Pacific Islands reconstructed in the visitors' thinking is not only a geo-cultural entity, but also a mixed entity of historical knowledge and reasoning as well as a myth agency of politics. Hence, Pan-social or cross-cultural elements are not created simply by the Museum way to guide visitors to see the exhibitions, but depend heavily upon practical reorganization of each visitor in the Museum space.
