Due to the prevalence of modern commerce and mainstream culture, many indigenous cultures around the world are rapidly diminishing. These cultures, with their unique primitiveness distinct from modern culture, often attract tourists. This study integrates the indigenous Yami culture of Lanyu Island, Taiwan Region, into innovative designs from the perspective of tourists’ understanding of the local culture. In this way, tourists can experience the harmonious coexistence of the Yami tribe and nature, while these culturally rich products foster deeper experiential and emotional resonance. This study employs the Mandala thinking method for concept expansion and the Osborn checklist method for the analysis and transformation of design elements. Subsequently, designers were invited to conduct on-site travel experiences, leading to the creation of a series of Yami cultural products. Through the evaluation and validation of cultural product assessment indicators, functional commercialized products were ultimately produced. This study aims to establish a design process for cultural products through this design case. It seeks to help users recall their Lanyu Island travel experiences and appreciate the often-overlooked cultural beauty, thereby raising awareness of cultural preservation.

This paper explores the narratives of the chinese woman novelist Shao-Lin chu’s trilogy to see how the problem of female sexuality and resistance to parental wedlock tragedy becomes a traumatic *** traumatic symptoms in the narratives are taken as Peircean signs for tracing the negative influences of traumatic experiences on the formation of personal identity and the associated depressive *** scenes portrayed in chu’s traumatic narratives of female and male sexuality are implications and representations of how sexuality is conceptualized and confined by the traumatic events while backgrounded with regulations and restrictions of a traditional *** stories of chu’s female narrators reveal the persistent and resisting feminine *** paper adopts the concept of feminist narrative to analyze the traumatic and sexual events in chu’s *** decoding and re-encoding of resistance and sexuality in the traumatic narratives prove that the narratological textual analysis and semiotic reading strategy together offer a solid approach to the discovery of the persistent traumatic impacts of the secret veiled in the narratives and reveal the probable strength of compassion that has its roots derived from deplorable trauma but later transforms itself to stimulate a positive reconstruction of the traumatic survivors’identity.
