In fact, I have become so lazy here, I'd be unemployable back home.

The only problem with that is, it can affect you adversely should you need to work on your return home. If you are fully retired, it is no problem whatsoever, but for a younger bloke, who might have to immerse himself into the cutthroat life of say working in London, he will be buggered.

A investment bank manager in the city, will just think 6 years spent in Baotou teaching english is a waste of time.

For young ones learning Chinese, studying business and trade in China is a must. China is really only any good for older retired fellows like yourself, or the independently wealthy.

Good day,
