True. I'm sure it's majority Asian-American but I found the cutest ones to be straight Asian. Of course, they were also the hardest to make things work out given the severe language issues.
Interestingly almost all straight Asians in SF are there to learn English.
I think it is unfair to group Chinese English with Japanese English ability. The English ability of mainland Chinese people is terrible (even though they are enthusiastic). Talking to them, even those who are well educated (grad students/professors) is like a game of charades. The problem with China is that most young people (20-30) started learning English at age 13 at school and their parents learnt Russian as a second language.
