Surprisingly expensive compared to many other places and there is a major language barrier for most western folks. You often end up hanging out with other nomads or expats for sanity. It's expensive to drink, and it's not really to make many local friends and very few speak English or any western languages. The internet is the killer for most folks and China is slowly closing down all the VPN connections from the commercial services, so it's getting harder and harder to find a way out for things like Gmail or even Google searches and even when it does work, it's really unpredictable. Some of the hotels and workspaces have always-on VPN connections to Hong Kong for your internet handoff which eliminates the blocking and is a big help, but this is usually at a cost that is passed on to you. I like Shanghai, but I find it very "showy". People want to make it clear if they have money, so you see lots of flashy cars, expensive clothes and "be seen" places. It's also amazing that you can go to a great restaurant and the table next to you will have six people sitting in complete silence because they are all on their phones. As others have said, you need to figure out a way to get Alipay or Wechat pay money on your account so you can pay for things. Even people selling vegetables in the market have a QR code so you can pay them with your phone. Didi is the local uber-like take service, and you can use western credit cards with it on your phone, and it's pretty cheap by western standards. Public transportation is good and cheap, too. Cool place, but not inexpensive unless you are out a way and a serious language barrier and a bit of indifference to customer service or dealing with westerners in general.
