Lots of little businessmen in China who need to learn some English but do not have the time to attend English Centres. It can't be done without effort of course.

Yep, that's certainly a good option for foeigners who can teach with Chinese spouses. As for me, I have reached retirement age and do not need nor wish to continue teaching. Teaching 16x 40/45 minute classes at a senior high school in a county aided by a Chinese teaching assistant for 5,000/5,500 RMB/month plus air fare allowance and travel allowance preparing just one oral lesson/week is perhaps the least effortless way to make money teaching English in China. It's a good way for older westerners with offshore investments and superannuated pensions due from western employers to last out financially until the pension years arrive.
That said, I've been let down rather badly by one of my pension providers from the UK, and that pension is now 4 months in arrears. I'll be checking at my Chinese bank shortly, and if no funds have arrived to date, I'll lodge an official complaint, with a view to getting the problem sorted once and for all.
