This article delves into the dynamics of online fandom in China through the lens of LinaBell, a pink fox character introduced as a mascot by Shanghai Disneyland in September 2021. Unlike traditional Disney characters, LinaBell lacks an official backstory or media presence. Yet she has rapidly gained immense popularity among Chinese Disney fans, largely through social media platforms like Weibo. Our study centers on the LinaBell Super Topic Community on Weibo, consisting of over 543,000 members known as “LinaBell’s moms.” Employing qualitative content analysis of posts and comments, this research examines fans’ creative work, including videos, fanfiction, and memes around LinaBell, in order to understand the collective dynamics of Chinese online fandom. Our findings revealed two main themes: the collective personification of LinaBell through fan work, and the formation of a parakin bond with the character. The findings highlight the transformative role of social media in contemporary Chinese fandom as well as unveil a diverse landscape of participation, creativity, and community in Chinese culture through the prism of platforms like Weibo.
