Can parents read their children's text messages privately?

Parents are guardians of their children and have the obligation and responsibility to protect them. Children also have their own right to privacy, which is inviolable. There is a reasonable side to checking children's privacy out of guardianship obligations and responsibilities. Because of lack of social experience when I was a child, I was easily injured. This is the gap between love and law! There is still affection between the two people. The most important thing is how parents can handle their children's privacy wisely, without hurting their self-esteem or dereliction of duty, and play a guardianship role. If the child's rebellion is due to lack of wisdom, it will not be worth the loss.
