About 10%-12% of us are left-handed, but not in China. Children who are spotted writing with their left hands are forced to change to their right.
As a result, you won't find left-handed people in China. And, not surprisingly, everything there is designed for right handers. So, if you're left handed and planning on visiting the forthcoming Olympic games, don't be surprised if you needs not catered for.
Mind you, what's different there! OK, there are lots of left-handed kitchen and sporting products available online now, but, here in the UK, every time we open a door or a window, go through the Tube gates, or operate a camera (the list is endless) we have to do it the right-handed way.
