I can only speak for my region and school.
I get the idea that Inner Mongolia is more laid back than some other areas.
I've been told that there are lots of foreigners in Baotou, but I don't see them. People still sometimes to ask to be photographed with me.
We had lived in Korea once before coming to China, so my wife likes the snow when we get it.
In addition to Korea and Thailand, I'd also worked in Cairo. It wasn't long before Baotou was in my comfort zone.
I'm paid eight months per year at this school, and that makes the pay comparable to Thailand, except that the school provides us with a very nice teacher apartment. My teaching duties are quite light compared to others. I'm required to be present to teach classes but I have no office hours. This almost always keeps my teaching hours at or under 45 hours per month, and this allows me to collect social security - usually. This is a huge help.
At every other place of employment I've ever been at, there's always been an anal orifice to deal with. Here, everybody is nice. No matter how busy people are, there is always time to help me, and they went to great lengths when we first arrived. One example is that when my father-in-law passed away, one manager lent my wife the money for airfare so she could return to Thailand. While I get a refund of a ticket to Thailand twice a year, my wife does not. Another manager lobbied repeatedly to get my wife the ticket refund.
One woman, very high up the food chain, has been especially gracious and along with her colleagues has made me very happy here. I've come to think of her as the most beautiful woman in China. There are three other teachers and an assistant who make large efforts on my behalf as well, and other assistants and teachers who watch after me.
I've been very fortunate in that I might be popular with the students.
The students, almost all women in my department, can be monkey girls. I once had to wrestle a telephone away from one student. She had a death grip on it and drew blood before I got it away from her. Aside from the phone-itis, they are far more polite than what I'm used to and some take it all quite seriously. One of my schools in Thailand had spoiled and stubborn boys who were impossible, even for some Thai teachers, to deal with. I don't miss that at all.
It is the PRC and one is sometimes reminded that one is in a police state. The big difference between China and Korea remains the writing system. Korean writing can be learned an an hour or two. Chinese requires an hour or two per day for months.
When I returned to Bangkok last January, I went bat shit crazy at my old haunts. So, next January or next July might be a good time to call it a day for this part of my life.
I cannot overstate how glad I am that I did the "not sensible" thing by declining a job offer near home and coming to China. I cannot overstate how fortunate I was to wind up here.
Your experience in China will probably be very different.
