Summary Anthropologist Roger M. Keesing suggests that avoiding traditional thinking patterns in contemporary anthropology is necessary. Studying not only fading or faded human social lifestyles but also on-going events are equally requisite; furthermore, to encounter problems, resolving them practically is also indispensable. It's worthwhile to apply this perspective to cultural studies. Since culture is a presence of the accumulation and evolution of human lifestyles, it's essential to explore the authentic meaning of it by the same practical attitude. From the perspective of Han linguistics, during the early years of immigration and reclamation of Taiwan, the culture mainly inherited from the China Han ethnic group. Later, merged with the culture of exotically colonial and socially demanding immigrants and then the rejuvenating native tribes and the recent Southeast Asian immigrants, Taiwanese culture has been transformed and fused into a multicultural appearance, which also manifests the embracing and respectful traits of Taiwanese society. Therefore, this paper adopts this principle of contemporary anthropology to explore the current situation of the cultural practice in Taiwanese design industry. Meanwhile, through the author's long-term, practical experience of wedding card design and by the application of the KJ method, this paper exhibits the cultural notions of Taiwanese wedding card design. Also, with the approach of cultural practicality, the author brings up three concepts that are worth considering for modern cultural design workers, which are enhancing the ample profundity of design by cultural practicality, establishing the adequate joint of indigenous studies and academic research, and forming the essential confidence of design culture in the post martial law times. Hoping that Taiwan will attain the foreseeable economic prosperity in the near future by the practice of cultural practicality.
