As a foreigner who lives in Shanghai for almost 8 years, the list would be a bit different:
1) pollution - Since the Disneyland has opened, things are improved. But above the regular days, it is depressing when finally the weekend came and you can't leave the 4 walls.
2) overpopulation - I don't mean the large population, but the overpopulation. There is no space for cars, yet everybody is buying, sometimes a two lane road becomes barely one, because one lane is completely blocked by parking cars and bikes going randomly. Parks are small and spare in the city. There is barely playground for children only expensive indoor ones.
3) People.. I know I know, but it drives me mad, you can only queue up like once in a year when nobody will come to the front to you. I can't count how many times I've seen that cars just blocking the ambulance in rush for no reason.
When you stop with your car because the road is blocked, it's guaranteed sby from the back will try to overtake you either from left or right. My friend had a light accident with a motorcyclist (50%-50%), he brought him the hospital and paid everything. Few months later he was dragged to the court and was charged for 28K RMB (~$4K) (including the bills he paid in the hospital, fortunately he kept the cc receipts, the repair of the bike cost like a new one etc. even if it is mostly paid by the insurance, very depressing to see this amount of fraud). And so on..
Of course you can meet nice and good people, but still the daily routine will be different (also gave up counting how many times i was almost hit by a car or motor).
4) The first green is like 4 hours driving. And not easy drive but bloody fight. Have to be fully alert, people even overtake you on the shoulder of the road + I can't recall I ever could drive without seeing accidents, see barrels or other things on the road.
5) internet - after 7-8pm it is basically cut, so overloaded, no website loads that is not hosted in the country. You have to use some kind of vpn for everything! ... your gray hair is granted. No form of video-chat works beside wechat. Skype though exists, in the current year, was really painful communicating with my parents.. as my experience goes only works during working hours or on mobile net. In this year when i go home, I started to consider it as an offline zone.
.. sorry to be honest, no pun intended. It is how it is (My wife is Chinese so Im halfway there also :)... and things are improving with time, just way too slowly, Except 2. and 4. that can't be really fixed. (can't imagine anytime soon that it will be a dream destination..)
