Weather:

One can draw a line horizontally through China to make a north/south split. The Northern half experiences hot, dry summers (over 40C) and fiercely cold winters (minus 20C in parts) whereas the Southern half has suffocating, humid summers (Chongqing, Wuhan, Changsha, Nanning are humid) but rather more pleasant winters compared to the Northern climate.

Pollution is rife in big cities and can cause problems with breathing (if your susceptible to this) but in all fairness, this has reduced in recent years.

Refer to the internet or a bulkier guidebook for area specific weather patterns as this short, general guide cannot possibly cover the massive area of China’s variable and sometimes extreme weather systems.
