If you want to persuade people something against common sense to be existed ,you have to prove it.
Hey, Don't make mistake, I am Chinese, not westerner. I know what Chinese women look like because I was raised by them,and married to them. Generally Chinese woman looks younger than westerners, I know that, but the Gym team is surely beyond that far.
It is hard for women to hind their ages, their faces, skins and manners would tell the secret. So if someone states some women could be recognised 12 when she is 30, according to my experience I say she could not be Chinese. She may be aliens or something else, but not Chinese.
Faking ages by China's olympics athletes is an open secret in China for years, so I dont need to google Bella Caroli to know which side should I trust.
I am not arguing that the age observations are wrong, just that westerners are generally not qualified to make them.I also believe that that government is probably using underage girls just because the younger ones tend to be more nimble and lose some of that as they reach puberty. China cares nothing for anything but gold medals and glory to show the superiority of China and Communism. Communist governments are not capable of not cheating if it enhances their results. Remember the Soviet Union and the other Soviet countries before the fall of the Soviet Empire and the genetically and physically male contestants that competed in the Olympics and other international Games as WOMEN.
