Anus City?
They really should come up with better names for the locales. Or at the very least, teach the actors to pronounce with more accuracy. They keep saying "gong-man" city, which means "anus" city. The "on" sound should be more similar to "own" (guong-man means "palace door").
I think whoever is writing the script put that in there for lols. Next film will probably be set in "cum-stain city" or something.
