Abstract
This research examines the knowledge constructed in political ironic discourses, which is associated with different models of practicing self-censorship, taking a case study of the 2017 Hong Kong Chief Executive Election via social media Weibo. Critical discourse analysis, the verbal irony principle and semi-structured interviews were employed to compare participants from mainland China and Hong Kong, including opinion leaders and casual users. This research suggests a three-stage analytical framework that clearly emphasizes the act of rhetorical discourse and the practice of self-censorship. As such, it reveals citizens’ intrinsic motivation related to self-efficacy, resistance or empowerment. This research argues that dissidents’ shared knowledge and ideology are structurally represented in the ‘binary opposition’ mode of rhetorical discourse, concerning the discursive construction of Hong Kong identity. The proliferation of rhetorical discourse, evolving shoulder to shoulder with Internet self-censorship, results from the complexity of politics, history and digital technology development within China.
