i would seriously keep myself away from Hainan and all its subsidiaries ,a very popular recruitment agency a while ago stopped accepting application for Hainan NTR captain due to the high failure rate during training but it is up to you.
If you go to China make sure to reduce to the minimum the chance to have any problem during training and applying for a type you are not familiar with to me is not the best option.
I know that money is good but trust me that's for a reason.
Try other airlines, maybe less money but better working environments
Again it is just a suggestion.
cheers
