I think the universities in western China may charge lower tuition fee like Ningxia University, Shaanxi normal University and Lanzhou University. Almost all of the Chinese universities have their own official website on which there are contacts info. I think you can just choose one and contact the school directly to get the procudures to study there. You may also go to the China embassy in your country to enquire about this, you have to apply for the student visa for your study in China from the China Embassy anyway.
