People breaking the rules should be put to justice, no matter whether they are Chinese, British, French or any other the hundreds of nationalities around the world.
To be truthful to the point: wearing masks in parks is not yet a rule legally speaking, but striking a person does break rules; this is clearly a simple case of drunk and disorderly and should be treated as so.
What I don’t like is the white wash was any non-Chinese are being portrayed on media; it will be pretty dangerous and when foreign internet groups get hold of this as it’s going to explode. And westerners are far more brutal online than Chinese are.
Really, there are already countries threatening to sue China or worse. And netizens want to destroy any support and rally the whole world against them. The term foreigner indicates 194 other countries….. Good luck China; some battles can never be won.
