I just flew a trip with a chap who fairly recently returned from a three year stint as a 73 skipper in China. If I was 15 years younger and single it sounded doable but some very strange procedures to get comfortable with. All comms were in Chinese, the Captain did all take offs and landings but the local FO did all radio work and inputs to the MCP after takeoff and until established on the approach. Massive leap of faith but he survived. There was a lady who was the company liaison for all expat crews and he said she was brilliant. The Chief Pilot spoke no English and smoked like a freight train so smoking on the flight deck was the norm. I was enthralled with tales of the Orient for our several day trip. Good luck with your choice.
