Despite that, China has a fertility rate of 0.93, which is among the lowest in the world, and certainly much lower than the US (1.6).

So it doesn't seem that that cultural difference boosts the fertility rate all that much.

china destroyed its fertility rate with the one-child policy. so that is not comparable.

That's an easy answer, but it doesn't explain why nearby/culturally related countries like South Korea and Taiwan have similar or even lower fertility rates, despite never having a one child policy.

And of course China's fertility rate now is even lower than it was at any point when the one child policy was in effect.
