In November 2021, the Hong Kong law on censorship was changed. It is not clear whether Revolution of Our Times (Shi Dai Ge Ming ) (by Kiwi Chow) is allowed or banned. Chow's movie's name is the later half of the Tong's slogan (liberate Hong Kong; revolution of our times) without former half, without the words of "liberate Hong Kong".
The rules say that Hong Kong "category III" movies cannot be shown to people under 18 years old.
