This is from an ex-pats view, but anyone welcome to chime in.
How do you compare the pros and cons of living in Kunming to other cities?
Chengdu? Qingdao? Xiamen? Nanjing? etc.
Or the big 3 (Beijing, Shanghai, Guangzhou)
And how about versus cities in Japan, Korea, Taiwan, etc?
I would say that Kunming is less snobby than some of the big 3, as well as having cleaner air, and easier access to outdoors and small towns.
It is also less expensive. That said, it is way more boring and isolated.
I guess I would say it is less friendly than the big 3 as far as people being comfortable with foreigners and people being social with strangers on a deeper level (conservative here), but still more friendly in other ways.
Compared to Chengdu, people here are more scared of or deal less with outsiders (including Chinese outsiders), and the ex-pat community is smaller, less jobs, worse food,and it has less resources.
But I would still rate Kunming higher because of superior weather, less sprawl, less air pollution, and a bit more spirit in the people.
The main issues I would warn prospective expats about here would be lack of job opportunities/low pay, ugly architecture (except green lake area etc.), all the normal china issues, and general boredom.
But I would recommend this place to people who really value good weather, manageable level of urban sprawl, slow pace of life, moderate cost of living, and would like to know more about ethnic minorities.
