Turn this on its head.
Imagine you are the girl in question, and you've worked your ass off to get to be the at the Olympics. And your dream comes true and you win.
And then everyone else turns around and says your a cheat based on your nationality and the fact that you have improved a lot (something that British experts have said is possible and common at her age).
Is that right? Is it fair that we immediately cry foul?
The Olympics is about sport not politics. And unless we can prove that an individual athlete is cheating, we have to give the benefit of the doubt; not simply be frankly rather racist in saying "oh well what do you expect from the Chinese?". Innocent until proven guilty is a bit of a corner stone of our precious democracy, and yet here are people being judge and jury based on no evidence.
If you look at a lot of other athletes from around the world, its fair to say that many from nations around the world have had pushy parents and had no childhood as they were all busy training from an early age too. Its part of becoming the best in the world unfortunately.
Not to forget that you are talking about the most populous nation on earth. Just to represent their country, they have to beat more people than anyone else. It doesn't take a genius to work out that breeds a culture where an obsession with training is going to go to its very extreme.
China definitely does have its issues with human rights, and I don't want to take away from that. However, I'm a little cautious on this particular subject. Why? Partly because there is just such a culture of achieving and pushing to achieve which is very much at odds with our British way of fitting in and not standing out. It doesn't necessarily make it wrong - more than we struggle to understand it. And partly, because I feel it just as unsporting to fall into the trap of accusing anyone of cheating because of our dislike of a country's politics rather than credit an individual for performance.
Unless you encourage the ideals of sportsmanship and democratic ideals, why would the population of any country with a questionable culture of ethics see it as a better way and a culture to be appaulded, and be of significant enough value to them to adopt instead?
