"Do you want to live in Switzerland?"
Translation:Bạn có muốn sống ở Thuỵ Sĩ không?
There's a standard orthography to the placement of tones. I don't know the rules but I've never seen -uy with the tone on the y. I think the y operates as the exit phone and thus the tone marker should be displayed on the core phone. Sorry, I don't know the correct terminology!
