yep! east asian countries as a whole don't have the Judeo-Christian belief of impurity or shame associated with faeces or gas. It's a common topic in Japan and Korea, people will literally say stuff in public like "I got mad diarrhea today" and it's completely normal lol.
Ok searched it up... Turns out "inferior to a fart" is a Japanese saying LOL and there are other Japanese fart-centered sayings as well
