How do you say "to do" When asking a kid what he wants to do when he grows up?

Question

The classic question (at least when speaking english) is to ask a child what he wants "to do" when he grows up. Now this "to do" is very vague - and, in a lot of instances, doesn't actually mean "do" (So much as "Be") I'm interested, in Chinese, how is this classic question asked? Is it "你长到以后想干什么啊？“ or is there a more natural way to say this?

Answer 1

你想当什么？你当成人想做什么工作？

Answer 2

“你长大以后想做/干什么？” is perfectly fine. “干” is just a little more colloquial than “做”.
