May I direct your attention to a nice piece of Google-hacking at Stryde-Hax (here and here) which shows evidence of Chinese governmental tomfoolery with regard to the ages of He Kexin and Yang Yilin. The story has also broken (first, maybe) at the New York Times, here.
Didn't we all suspect this all along? My profound sympathy is toward these Chinese girls. Rules are rules, but apparently they are new rules, because I think Nadia Comenici was 14 when she scored her perfect 10.0.
