China has a ton of problems that aren't readily apparent unless you are feet on the ground. The majority of the culture of china is, "dog eat dog" in that you will be scammed and taken advantage of unless you speak fluent Mandarin.

You will run into problems with excessive Chinese bureaucracy both with the government and services you need. The only way to break through is with a bribe.

Things we take for granted like food and product safety are secondary.

In the first month, I got incredibly sick for a food born parasite (this was from a good grocery store too nonetheless).

Don't ever eat from street vendors (google gutter oil).

You also run the risk of getting physically attacked when relations with America are rough. I heard stories of a guy that got jumped by a group of chinese men after Trump was elected. He didn't even vote for him and the police did not care.

China is the type of place you visit, make a bunch of money, and get out.

In all honesty, you'd be happier living in a 2nd or 3rd tier Benelux or Dach town.
