China has a catch-all law called "Picking quarrels and provoking trouble". Basically, they can arrest anyone they like with this vague law. Why are you breathing so hard? Are you trying to give me troubles with your breathing? What?! You are arguing with me that you are just breathing normally? Are you trying to pick quarrels? Arrest him!!! Why is there hair on your head? Are you trying to give me troubles with your hair? What?! You are arguing with me that you are born like that?! Are you trying to pick quarrels? Arrest him!!!
