I have worked in small town Taiwan for 3 years, small towns in South Korea for 2 years, 6 months in another second tier city in China but none of that was as extreme as the isolation you will experience in Baicheng. There are NO social outlets in Baicheng unless you can speak Chinese. I tried to be good friends with the other foreign teachers but it was a struggle due to their own personal issues, as they could have been a good outlet. Unless you are content with your own company for long periods of time I recommend nobody ever goes to Baicheng. It's a long way to anywhere including Changchun.
