No, I’m not sure what this is suppsoed to be representing, but it looks legit. Wiki says it’s “Medicine hawkers” (???) while a Korean site ran through Google translate said it was a demonstration of “construction techniques” (??? again)

If anyone has anything to say about it, they probably know better than me, lmao

Looks like a bunch of taekwondo nerds having a demonstration

is this Gangnam Style?
