Teaching in China, West is not the best

So I will teach in China when it opens up and I want to know where to go. I have heard from other South Africans for your first job it is easier starting in a smaller city. I also heard the west of the country like Tibet and Qinghai province especially west of Chengdu is not cool. I won’t be going to Xinjiang obviously, I don’t want trouble. I think any city with a large muslim population would be best to avoid. The biggest cities I don’t like so can suggest from your experience which places are cool fun relaxed places?
