Why are young people not having children nowadays?

Let me tell you a secret: it's not that they can't afford to have kids, but that they don't dare to entrust their children to this system.
You think it's a money issue? You're wrong.
Families earning 30k yuan a month still don't dare to have children because they've calculated a figure: from kindergarten to university graduation, excluding tuition fees, just the extra costs to prevent their children from being eliminated by the system—tutoring classes, interest classes, school district housing, relationship fees—is an endless pit.
