Just a few questions

Hi there,

This is a really interesting topic, I enjoyed reading! I have a couple of questions - what do you mean by the term " informal underage marriages". Are there some child marriages that are formal? What does being informal or formal mean in this context? I was also wondering if there are any activists or advocacy groups in China that help teen moms or that seek to educate teenagers on sex? How does intersectionality come to play in all this?
