Interracial marriage has increasingly gained visibility on Chinese social media platforms, especially African-Chinese marriage which has been popularly represented, sparking heated discussions publically. However, although several studies have touched upon interracial marriage with analyses through political and geographical lenses, few studies investigated the media representations and mediated comments towards African-Chinese marriage in China as it has become a hot topic on Chinese social media platforms recently. To fill this niche, this study explores how African-Chinese marriage is represented on Chinese social media through mediated public comments, and what ideological implication of represented subjectivity of male and female in African-Chinese marriage. Through feminist critical discourse analysis and intersectional perspective, it found that ambivalent masculinity and constant femininity are constructed in African-Chinese marriage through comments where Chinese males are predominantly represented as positive figures, while African men are greatly dehumanised and criticised. As for women, although public attitudes are distinctive towards Chinese and African women, they, sharing the collective identity of females, are restricted in the traditional conception of gender dichotomy. Finally, the social contextualisation of such representations and potential ideological implications will be generally discussed.
