"My parents were hippies, and the story is that they went through a dictionary looking for a beautiful word to name me. They nearly called me Banyan, but flipped a few pages on and reached "China," thankfully. The other reason they liked it is that "china" is Cockney rhyming slang for "mate." People say "my old china," meaning "my old mate," because "china plate" rhymes with "mate."
