I realize this question isn’t about an obscure topic from 200+ years ago, but it’s history and I’m curious.
I’m not very familiar with the One Child Policy besides what I’ve heard in pop culture references. In the US it’s common to have children in a second marriage if the couple is still young and want children, even if one of the individuals has a kid from the previous marriage. How would this have worked out in China during their One Child Policy? Would they be allowed to have another child since it would be one child for the other individual?
The One Child Policy was not a static thing, and the specifics of the policy varied by region. In the case of remarriage though, all the regions had pretty similar policies. (I'm assuming you're asking about the older period, per the 20 year rule.) Previous to the end of the One Child Policy, if, between the couple, only one child carried over from a previous marriage, then they could have another. That is, if a remarried couple have a total of less than 2 living children, another live birth is permitted.
In some regions, this was only permitted if the existing child was assigned female at birth. In other regions, it was permitted regardless of biological sex.
There were the usual exceptions for this for certain Chinese minorities where the total number of pre-existing children can be 2. In the case that one spouse was Han and the other a minority, the exception applied if the Han spouse was marrying into the minority township or village.
