There is a lot of money to be made as a pilot in China, but you have to be very aware of what you're getting into, and I would say it's very debatable whether it's worth leaving a secure job in Europe or the US.
Some issues to consider:
1. The medical is always a concern, not just the initial, but every annual medical, and can easily bring your Chinese career to an early end.
2. Although you may pass the selection simulator, checks after that can be very unique to China (and to the individual instructor) and can cause a lot of difficulty and often absolute failure.
3. It is without a doubt a culture of blame and being a foreign Pilot you will be the first out of the door in case of any incident.
Having said that if you make through the system and are consistently able to pass the medical it can be rewarding.
