If parents want to educate their children correctly, they must first set an example. Parents are children's first teachers, and their words and deeds will have a very far-reaching impact on children. This kind of parents lose their temper at will in public, never consider their children's feelings, punish their children in public, and don't take into account the ideas of people around them, so they can't set a good example for their children.
As an adult, you should keep your emotions stable, especially as a parent, and you should not lose your temper with your children at will. Judging from the behavior of parents kicking their children away, this parent must be a very grumpy person in life. Grumpy emotions will also infect their children invisibly, or make them as grumpy as their parents, or make them introverted and inferior, which is not conducive to their healthy development in the long run.
Parents should go deep into their children's world and treat them equally, instead of trying to control their thoughts and behaviors with their parents' authority. Otherwise, it will only pull the distance between children and parents farther and farther. Only by truly becoming their friends will children be willing to open their hearts in front of you and communicate with them in depth. When educating children, we should give priority to encouragement and praise, rather than beating, cursing and criticizing at will.
