Children are being kidnapped. Believe me, if the local Party official came to a house in the West and said 'we're taking your child to athletic school, aren't you happy!' it would be considered kidnap.
I suppose you could whisper in the child's ear 'remember to under perform when you want to come back'.
Now that is ridiculous.
Think of the great shame you would bring on your family and your entire village to know that your family rejected the opportunity to have your child participate in national athletics. Also, you have a nice house and a nice family here and it would be a real shame if some kind of terrible accident happened to them.
Ah, you've changed your mind about your youngest daughter participating. Excellent. She will bring honor and glory upon our great nation."
