In Hong Kong on Tuesday, Claudia Mo, Jeremy Tam, Kwok Ka-ki and Gary Fan were released from prison after spending more than four years there. They are among 47 activists arrested in 2021 for their roles in an unofficial primary election under the Beijing-imposed National Security Law. Marco Werman speaks with Kris Cheng, a reporter from Hong Kong currently based in London, about the significance of this release and what is left of the Hong Kong’s pro-democracy movement.
