I agree, bigisjiejie. I have no doubt that the Chinese federation knows exactly the date its skaters were born on. It's one thing to be confused about ages in a personal context, but this is a big, powerful, experienced federation with many high level athletes and I have no doubt they know the rules.

I'm willing to believe entering Kexin Zhang and maybe even the 3 pairs entries were errors on behalf of both the Chinese federation and the ISU, but submitting fake ages for figure skaters, as it is currently rumored, is blatant cheating and needs to be addressed and stopped.
