Do a LOT of research. Then get a medical. Realistically allow a year for training, then another year or two as a flight instructor building experience for low wages. Then you might have a shot at an airline job. Depending on where you go, it could take 3 - 20 years to get a command, then as long as it takes to build the command time required in China. One thing I can GUARANTEE: In aviation whatever you think is going to happen, won't!
