The one thing that they don't mention is the female children that are abandoned so that the parents can try for a son (due to cultural preference for a son to be the family successor and support the parents in old age). (i.e. not aborted, but born and then abandoned; causing the need for orphanages to take them in)
it is illegal in china to check the sex of an unborn child (of course if you pay enough at private clinics, you can still do it). Public hospitals probably will not dare to do it.
I assume that maybe the abortion is too expensive or the check is. This might only be happening in rural (i.e. poor) areas. I don't know all of the details.
In the example that I saw of one of these orphanages, the girls were all in their teens. Maybe this is a problem of the past (due to newer tech)?
Portable ultrasound machines is the reason. Now it is cheap and easy to determine fetus gender, rather than waiting for the child to be born before you decide to abandon it.
