Hi this is Natalie~
I come from Chengdu (my lovely hometown is famous for panda and spicy food!), then study and work in Hong Kong for several years (so I can speak Cantonese). Before I came to Hong Kong, I studied Business in Sweden for one year with full scholarship.
I major in Cognitive Psychology and now am at the beginning of my research career in neuroscience (it's very interesting to know how our brain works!)
I have several piece of experience of teaching foreign adults/kids Mandarin. I also very much like to learn foreign language and culture. I know a little bit French, but I almost forget everything in Swedish :<
I also work as teaching assistant and give tutorials to undergraduate students at university.
It really depends on your target: written vs. spoken, professional vs. daily, etc. So it's important for you to narrow down your learning object.
It really depends. But from my experience, you can learn very quickly as long as you are exposed to an environment full of your target language.
(I had such experience: I stayed with Swedish friends full day, and was forced to speak Swedish/English full day, then when I met with my Chinese friend, I spoke English to her because I didn't "switch back", lol)
