I read on a nother site that he actually has 31. If you look at the 4th picture down you'll see on his right thumb a small nodule. That is another very under developed digit.

The boy looks pretty old. Why there were no pictures at his birth?

And, why do this things only happens in China?

If it ain't broke don't fix.

He has fourteen fingers. Cause fingers are on your hands. And he has 30 phalanges, which are fingers and toes. It's anatomy and common sense. Learn it.
