But cheap beer there is plenty...Chinese beer will give you a headache and Chinese liquor will make you sick. Overall the cost of living is similar to the USA.
The best part of the job is vacation but the new contract gives less and less. Vacations are denied and often rescinded. Many pilots are forced to work during planned vacations and aren't even allowed to take the vacation they've accumulated.
The commuting schedules are better but after expenses you aren't making as much money and they will fly you very hard in the two weeks per calendar month that you are on duty...as much as 80 hours. There is no sick leave allowed so if you call in sick (even fatigued after flying six hours already) they will take a vacation day from you.
There are so many limitations to vacation that if you don't plan on living almost full time in China don't bother to come.
Pretty much everything else is a sacrifice of lifestyle so don't expect to hear any upside other than the money...which is inarguably very good. But at what cost?
I also don't recommend permanently giving up your job back home because many (yes many) pilots fail out of training after getting on payroll and moving to China...the risks are high. Failures are most often for trivial things that have little to do with your ability as a captain.
