In this study, a Chinese fansub group - QAF was selected as the research object, and the online observation method was adopted to establish a long-term trusting relationship with the fansub group members. The researcher observed the activities of members in the group, and conducted in-depth interviews with group members to study how they construct their own identity in a virtual community, and how the textual reproduction behavior in fan culture context reflects the characteristics of “affective play”. The research shows that the concept of “affective play” is embodied in the textual reproduction process of the members of the fansub group, and the emotional factor is an important factor that affects the textual reproduction behavior of the members.
