Have you ever been to China?  china is a hard white substance made from clay. 瓷器

Lol - Catlleya Liu; I see what you did there. I've been to China 5 times, and Taiwan once. Have you ever been to Southern California? 

Seems it never rains in Southern California
Seems I've often heard that kind of talk before
It never rains in California
But girl, don't they warn ya
It pours man it pours.

I've been happy, sad, annoyed, ecstatic... and I've been a teacher, a waiter, an uncle, a friend... but I've never "been china".

Do you mean, have I ever been to China?  Have I ever travelled there, and then travelled home or somewhere else?  No, I haven't been to China.

Where would one start? :)

I have been TO China many times.I was teaching there for the last 3 years.

No, but I'd like to go someday to Great Wall. =D
