What if it`s as bad as you say she was worked to death in Hangzhou and ended up with double pneumonia.

I have lived in Hangzhou before, and Hangzhou is light years ahead of Hohhot in terms of living standards.

Winters in HH are brutally cold, think Siberia, rather than subtropical south east china cold and damp.

Better not to get into an argument with many of the locals, as they are a tough breed up there.

Hope she will be ok.
