Simon Cheng, a pro-democracy activist from Hong Kong, experienced detention and mistreatment in China, leading him to seek asylum in Britain. His activism continued in London, where concerns about China's surveillance and harassment of dissidents persist. Recent arrests of men charged with gathering intelligence for Hong Kong underscore the fears of the broader Hong Kong diaspora in Britain. Activists in exile, like Thomas Fung and Mr. Cheng, together with other Hong Kongers in Britain, continue to engage in the pro-democracy movement. Those resettled in Britain face challenges and threats, leading to a community marked by anxiety and caution. Despite the risks, some, like Vivian Wong and Catherine Li, remain vocal in their pro-democracy stance, finding a supportive community in London. The arrests in London have brought renewed hope to activists, as they see it as a critical action taken by the British authorities to address threats to Hong Kong people.
