I do have doubts about her age but what can you do ?
I read an article that IOC have requested an investigating on this. But what can they prove ?
She has 2 (even older one) passports, government issues id and birth certificate with same date showing her 16.
I don't think they will allow dental test so clouds will still remain. But she might well be right too ..afterall these Chinese are really small. We have one such at work who really looks like a school kid.
Its just genetic thing. Can't compare with American Girls at all.
