The OP is a young, very young actually, woman who claims to be American. I found her on QQ and if the pictures she has posted really are her she appears to be early to mid 20's and Chinese though it's of course possible she is some other sort of Asian. I wrote to some teachers I know at GDOU, who have been there for years, and they say they don't know who she is. I agree that trusting anyone at GDOU is a tad foolhardy but this whole thing smells fishy to me for some reason.
