Forty-seven Hong Kong democrats and activists were charged on Sunday with conspiracy to commit subversion, in the largest single crackdown on the democratic opposition under a China-imposed national security law.
Sam Cheung, a young activist and a participant in an unofficial primary election last summer, was charged after reporting to a local police station, dressed in a black mask and accompanied by his wife.
"Hong Kongers have a really tough time these days," he told reporters before entering the station. "I hope everyone won't give up on Hong Kong ... (and) fight on."
