Thanks everyone for the replies, it is much appreciated.
I am looking at the lower end of China as I am used to a subtropical climate, living north of Brisbane but south of the tropics. Guangzhou comes to mind or even a bit further west such as Guilin. I apologise if my understanding of regions in China is limited, my only Asian travel so far in my life has been to Hong Kong in 2000.
My English is excellent, both in grammar and vocabulary and I have very little accent because I was born in Britain but travelled to Australia as a youth. I have no degrees, but I have completed all bar 6 months of a BSc with a distinction average and I am also rather astute at body language and facial gesture reading.
I have also home schooled my own children for 5 years as well as tutoring some students at University as well as high school students. Mainly in math and physics.
I am not trying to show a lack humility here, simply answer some of your concerns with as much honesty as I can. I actually find it rather uncomfortable revealing personal details about myself under normal circumstances.
If it makes any difference, I am in my late forties.
Thanks once again. Also, feel free to PM me if you have any other questions.
