Three Baby Policy, Twenty-three baby policy. Doesn't matter what the official line is. Too many societal factors against having any babies for many Chinese.
The GM of my HK laboratory, he is from Shanghai and has 2 kids, when u have money the one child policy doesnt matter LOL
edit: his kids are of Uni age so this was back in the day.
I know of a country in which state legislators are essentially attempting the same though not capping the number at three...
My mum was born in China and she has 3 siblings so it was clearly not always enforced, I don't think that her parents were particularly affluent either.
Perhaps China is experiencing the same problem that SK. and Japan are: a severely low birthrate despite, in Japan's case, serious incentives for expecting couples.
