If I were at home in the UK I'd repair the blades myself but I don't want
to retool for China. Ceiling fan replaceable blades are easy enough to purchase in UK.

Wake up and smell the coffee Blodwyn. You're NOT in the UK......This is CHINA!

Stop complaining and go buy a new fan. It's Autumn now so they're probably on sale. You could possibly pick one up in your little hick town for about RMB20.
