Depends on where you will be flying.
Most airports will be ILs and probably Radar too.
Generally long runways.
ATC is not bad - totally inefficient and generally illogical but in my 5 years I have not seen a TCAS RA or event that could become a near miss. One thing to beware of when the wx turns nasty - they have a habit of closing airports or airways and letting you fend for yourself to some divert field you have never been to before.
ATC English not the best at provincial airports or even major airports but you will get used to it. Major airports always have the supervisor close by to take over when you have an issue or emergency (as a colleague did in pek and it was well handled by ATC)
China is getting better but is now western europe or US standard, but it is better than average for the region.
