When I was in school, my Japanese teacher told us that in Japan it is actually considered to be somewhat rude if you don't slurp your noodles. I wonder if China is similar in that regard.
The payment system sounds cool. Interesting.
Another great post.
Here in China it is the same. As all over Asia I guess.But I can't see any correlation between being polite and slurping. Well...sometimes it is okay to not understand another culture.
Maybe someday I will make a post about payment system here. Thanks for an idea.
