I was born in Mainland China, but I have been in the States for a a bit over 6 years. I would say I'm reasonably proficient at both languages enough to call them native, and having picked Spanish as an elective, I'm currently looking for someone to consult with when learning Russian. I've been warned that Russian isn't the best language to take on my own, and would certainly appreciate constructive criticism as feedback. If anyone is looking for advice on English or Mandarin, I'll also be more than happy to help you.
