Thanks for clarifying things in relation to other countries.

Apologies, I really didn't make it clear that I was only writing about my own currency - Sterling. When I first came to work in China the exchange rate was almost 15 Yuan to 1. Today it is 9.3. The strength of the currency seems to be impacting on some Chinese exports, and although some of this can be attributed to the global downturn, and reaction to the various product scandals, I just look at how much I have now.
