Comments of chapter undefined of Transmigration: Lady Chi Woos The Ice cold Professor Jun

I love this story, but there is something a little confusing. They spoke about the one child policy being in effect, and fearing that she wouldn't be able to get a husband if she adopted Mei Mei because she wouldn't be able to have a child with her husband. It was my understanding that second mariages (so to speak) could produce one additional child. And later they keep talking about pressuring them to have more children after almost losing Mei Mei. Is the one child policy in effect in this universe, or not?
