Next move…thoughts on China?

Currently exploring next options. Currently at a decent school that also is considered a hardship post, so package is healthy. I have 3 dependents and considering next moves. One thought is China, as I hear packages and cost of living are quite good (obviously this depends on lifestyle). However, I’ve heard from people that expat families often struggle and I’m wondering why.

Any and all advice is greatly appreciated. I get that it depends on schools and cities, just looking for overall thoughts. Worth considering or look elsewhere?

Thanks in advance.
