I am 63 years of age and deserve much better, and I will definitely be treated much better outside Mainland China.

You are one of those rare older blokes who has built his life outside China, the problem is for many blokes in their 40s and 50s in China, with chinese wives, China is their future, like it or not. As for being treated better, you don't seem to like Central Asia or Saudi Arabia much either, even though I have a friend there in his 40s who reckons he can retire soon on the salaries they pay. Fat chance in China, but then, even as a professor, I guess you know that!!!!
