I would have thought that the pound being low is not ideal for UK expats because they get less RMBs for their pension. But if they use RMBs to pay a mortgage in the UK for example, then a low pound is better.

Quite right ,Observer. But I convert RMB into Pounds here in China and then transfer it to my British bank where it's not touched, but I do get some interest. Yes if you have pensions it's best you don't spend your pension in China at the moment. If you can get it sent in pounds and remain in pounds that's okay for now. I get a small military pension and another pension but that never gets to China.
