Everything you say and do is in the eyes of the child. Be serious and open-minded in front of children, and children will naturally listen.
In daily life, you can tell your child a little story about modesty intentionally or unintentionally.
When children hit a wall in their study or daily life, they can help make suggestions, and at the same time, properly mention the good habit of being serious and open-minded under education.
Over time, children get used to it.
Children have their own way of thinking. Don't think that children can be unreasonable, impatient or rude just because they are not sensible. Treat children equally and they will give you an unexpected future.
