I'm writing a self-introduction and need help with some translation I need to write a brief self-introduction to find a well-fitting host family for a trip to China, but my language ability is very limited (I'm in my second year of learning Mandarin). 

What is a simple way to write "I would like to look around/it would be fun to explore", "I enjoy people watching and am looking forward to learning more about Chinese culture", "I'm shy but I enjoy getting to know people/but I want to make friends", and "I'm half Chinese"? 

I tried looking it up first but didn't have much success. It seems like my own (or google translate's) word-for-word English to Chinese translation might be very awkward and there are some words I just haven't learned yet. I would appreciate any other recommendations for writing a self introduction because I know mine is very awkward.
