candenizkusu: I realise Turkish and English are very, very different languages, but you're going to have trouble learning the rules here unless you speak either English or Chinese fluently. The information you want is only available in those languages.
Don't try to do too much, too soon. Apply for your scholarship, learn Chinese. Then, when it's the right time, think about your business. Focus on one thing at a time
I'm not sure what your gf means. You can certainly start a business in Turkey and then open a representative office in Taiwan. But that would be a really, really bad idea.
