It's mandarin. All major comps conduct business there now. China now is what Japan was back in the 80's. i'm kicking myself for not learning mandarin in high school
Definitely. I don't think people realize how frequently Mandarin is used in the business side of fashion. Sure, on the outside people speak English or French, but on the inside it's completely different.
^ You've got a nice advantage by knowing three of the biggest languages! I've met someone from Morocco who speaks Arabic, French, English, and Spanish, and he says that there are plenty of high-fashion stores there. However, French (not Arabic) is the main language for economics/commerce in Morocco.
