?k lets be realistic, its a fact that the chinese are very very strict but this video is going to the extreme. Especially in the part that the olympic diver was not informed about her mother's cancer issue, which was her father's decision not from the chinese federation or something.
Now for the gymnastics, the training is harsh and extreme in every country. I can guarantee that from a personal experience in greece.
We trained a lot in the same hall with gymnasts (little girls mostly 7-10 year olds) and all this barbaric stretching is part of their routine. We would hear screams of pain every now and then, so basically the question should be whether is it worth it to be a gymnast when the competition is so harsh
