This study aims to explore the differences in the ocean writing between writers Syaman Rapongan and Liao Hung-Chi. First, in terms of the depiction of the fishing and seafaring experience of both writers, Syaman's shooting fish while diving and Liao's fishing by boat show the different perspectives in examining the ocean, i.e., the views above and underneath the sea level. The concept of ecosystem conservation can be found in the ocean writing of both; however, Liao discusses this issue based on the reflection on "modernity", whereas Syaman focuses on the Tao people's traditional culture in order to pose a challenge to Han people's "ecosystem conservation." For the depiction of "religious faith," Syaman often writes about the faith in the ocean, good spirits, and evil spirits to express his understanding, and his desire to find the root of Tao culture, while Liao's depiction of the faith upheld by fishermen reveals the imagined mystical, supernatural power that can ensure blessings and prevent misfortunes. For the thematic expansion of ocean writing, Syaman tends to adopt the idea of inheritance, a longitudinal expansion, by portraying old Tao fishermen to show the inheritance and long history of Tao culture, while Liao tends to present the wide spectrum of the fishermen's life, ushering readers into all kinds of stories on the fishermen's brotherhood against the backdrop of the sea and the deck, which is a horizontal expansion. Finally, for the language used in writing, Liao shuffles between different genres of prose, novel and poetry, while Syaman's writing integrates Tao's thoughts and Chinese language, exhibiting a writing feature different from Liao's.
