FYI, the preferred term is Asian, not Oriental as Oriental describes rugs, not people.
Back on topic. This is pretty nitpicky, but I can't stand it when movies and shows that have a modern submarine, and show bubbles coming from its propellers. This just doesn't happen with modern submarines, possibly even old WWI & II subs. Those little bubbles are the results of what's called cavitation and sub drivers hate that. This is because those little bubbles will pop before too long and the noise from the bubbles popping can be heard on modern passive sonars, and if there's one thing that sub drivers hate more than anything else is noise coming from their boats.
