I would not recommend going to NingXia. You are better off trying other places. Foreigners have very little leverage in places like china as it is. If you work in Ningxia you will have no leverage whatsoever and experience the full brunt of Sino Xenophobia. You want to work overseas so you can enjoy life. You don't want to live with your head down and always be apologetic just for being a foreigner. Getting treated like a doormat brings on depression and a destruction of self worth. I speak from personal experience, having lived and worked there. You can take a look at the "Alan" poster's advice on how the PSB treats foreign people to know that this is a general reflection of how the local Chinese there view everyone. You will not make real friends there. Keep looking.
