Japanese, Chinese (Mandarin) ,Korean, or Taiwanese ?

you know ive actually notice that(japanese ppl are more keen on the idea of just speaking japanese,not that im gonna say all japanese dont wanna learn another language or dont speak other languages cause im pretty sure they do.)and many chinese and koreans that ive seen or known(speak more than just there native language many just chinese and koreans.) but back to the real question..umm since iam bilingual i would not mind learning a few more(japanese,chinese,korean.) XD heard it was pretty hard but im up for the challenge.

Mandarin , due work improvement skills

I'd pick Japanese

Sort of lucky since my parents spoke both Vietnamese and Japanese to me, so I understand them both fluently. I do lack when it comes to Japanese, honorifics and such but eh, I get by.

Although Mandarin is the official language of China, unless you're working in government (why would you want to?), Cantonese is far more beneficial day-to-day since in most populated areas they speak it.

No clue about the other two.
Speak Vietnamese, any shop with owners who are Vietnamese always give you sweet deals. #1 pirates YEAHHHHHH!!

i would take japanese, korean or Chinese

why limit yourself when you can learn everything?
I'd say all
