Chu Kai-pong was convicted for wearing a “seditious” t-shirt. A new law has greatly increased the penalties for acts deemed seditious by the courts.

A Hong Kong man was sentenced to 14 months in prison on Thursday, making him the first person to be convicted under a strict new national security law.

Chu Kai-pong, 27, was arrested for wearing a t-shirt reading: “Liberate Hong Kong, revolution of our times.”

The day he chose to wear the shirt was also seen as significant. Not only was the slogan used by anti-government protesters during a wave of demonstrations in 2019. he wore it on June 12, the fifth anniversary of the day demonstrators surrounded the city’s legislative council complex.
