I lived in Dalian for 5 years. I loved it there and wish I was still there

Anyhow, I don't remember any real problems with the "hello's" but would occasionally get some staring, usually with migrant workers rather than the locals.
I frequently was approached with the "I'd like to speak English with you" but 99.9% of the time it was on campus. I would say sure, while I am walking home but no longer.

The student would always agree but be so 'sad' when I said bye, I live over there and leave
