I am not at Tianjin but at another Chinese carrier. The flying is hard work but the pay is huge. Tianjin is a dirty, smelly, cold city and expect 1-2 hour delays on most flights while flying out of there. Schools for kids are expensive and usually out of your own pocket. The medicals are difficult but passable until late 40s then the pass rate decreases exponentially. Training is almost non-existent so come prepared or you won't pass. The culture and flying environment is vastly different from an Asian perspective and a Western mentality. QAR information is sacred here and you can be fined or punished for non-compliance with established flying parameters. Overall China is what you make of it. There are big growth opportunities now but all that can and will change when the Chinese economy takes a downturn. The Chinese FOs you will fly with have very low experience and speak english fairly well and are eager. Housing is about $1500-$2000 per month for a 3 bedroom apartment. Crashpad type living is cheap if you are single. Chinese women are readily available if you are single. If I were a US regional pilot on the 145 I think China is a good option, if you are a current Captain on the E-190 you mght be better staying in your current job. If you are a 320 Captain look elsewhere in China. Best of Luck!!!
