Disturbing the peace comes from the Anglo-Saxon common law breach of the (King’s) peace[1]. Certainly, it’s a very broad law that I have seen overused and abused by British police (as another disturbing example of police acting badly) but you’ll need a more specific complaint for it or its application to be used in the same breath as the behaviour of China’s government towards its citizens.

People arrested for disturbing the peace in the US won’t disappear or end up in a re-education camp where their organs may be harvested.[2] Hong Kongers are certainly fighting for the right to remain under common law, there’s a clear difference in theory and practice.
