Every family has at least two children from where I grown up, even the official of the village. More like the case of speeding. You are not allowed, but you can get away with it, if the police are not there or feel it is better for him to not give you a ticket.
even a lot of Chinese are surprised when I talk about this with them. So be careful about the media's report. (they report what they think it is true, but might not)
The same cops that would flush some weed down the toilet so you don't get thrown in jail or not give people drunk and disorderly tickets would be akin to a hospital's staff not registering a child so the family could try for a boy.
It also helps bolster the war on women narrative. Here's one think tank that propagates the sex-selective abortion in China: [1]
Here's a mainstream article which gives a weak strawman argument then concludes there must be widespread sex-selective abortion in China: [ 2 ]
And this article goes even farther out on the line, saying the Chinese women were "forced" to abort their daughters, not using evidence to verify the theory, but using a piece of artwork by a French artist to propagate the idea visually: [3]
All of these stories must be critically considered in light of the new evidence by the Kennedy-Yaojiang paper. (and obviously we must also critically consider Kenney-Yaojiang).
