Abstract Since Chen Yu-Hui published ‘The Family of Sea Goddess’ in 2004, it has been highly valued by the literature academic community. However, there are still some questions unsolved. For example, why did the author arrange a foreigner getting involved into a whole family story? What was the purpose? Furthermore, if Ling-zi, Ching-zi and the author are the main shaft of the book, why does Ling-zi and Ching-zi’s leaving a failure and determines their miserable life while the author’s leaving and coming back successful? What is the key point? Upon the unsolved questions above, the writer thought it is necessary to discuss and analyze deeply this book again from its subjectivity. This essay will discuss from Ling-zi, Ching-zi and the author’s leaving, then how the subjectivity was established. Subject establishment is the only chance to prevent one’s destiny being duplicated. Through writing the family history, the author had the chance to review where she came from and reestablished her subjectivity. After reviewing the family story, the author was able to see the helplessness of her close relatives with a total new angle. In the meanwhile, she was able to put herself into the right ‘position’ with more deeply understanding.
