Parents and teachers tell their children some truths and instructions, and children will think in their own minds first, and then choose whether to listen or not, and accept or not.
In the past, when teachers and parents gave orders, children were obedient and respectful. How dare they say "no"? It's very different now. Adults say one, children will probably say two three four five six! Adults say that children can make three or five sentences. Now many teachers and parents come from obedient children. When it's their turn to be qualified to talk about people, they are broken, and they can't control their children if they want to "control".
