This type of event happens all the time in China, whether bikini girls or bare torso dudes. They never get arrested, even less prosecuted for it.

Sounds like beta Chinese boys couldn't stand the sight or handsome alpha Foreign males.

I can imagine some nerd type local dude witnessing the parade, "Oh no, they are violating core socialist values!".

Now you will excuse me, I have to remind the cat who is the dominant male at home because I am so insecure and stuff.
