ABSTRACT Building on a feminist critical discourse analysis, this study reveals the mechanism of the continuous reproduction of hegemonic masculinity in a Chinese manosphere, Hupu, the biggest sports fandom platform in China. As an ideological foundation on Hupu, hegemonic masculinity directs misogynistic practices (e.g. sexualization of women and misogynistic lexicon development) and shapes an imagined community of toxic brotherhood. In turn, the misogynistic practices and this community of brotherhood also reproduce hegemonic masculinity, ensuring a cycle of the maintenance of a toxic manosphere. We further consider the socio-political context in contemporary China to criticize how state power, platform affordances, and hegemonic masculinity are intertwined and jeopardize Chinese feminism both online and offline.
