This question is asked backwards. What should be asked is: "Why can't parents always share the same frequency with their children?" Why do you say that? Because parents have been "formatted" by social rules, while children are not, they are in a state of free development. How can this be the same frequency? So the question should not be asked like this.

First of all, parents who want their children to have the same frequency as their parents have a strong desire for control. They want their children to listen to themselves and live and study according to their own plans. However, parents will think that their children are disobedient and ignorant. Whenever their children are a little uncomfortable, the frequency is different. But such parents please think carefully, which adult didn't grow up from children, constantly experience various rules, cut off the edges and corners in various experiences, and gradually become a person who adapts to the "lattice life"? It's unnatural for you to let your child adapt to these squares from the beginning.

Secondly, what is the same frequency? The main thing is thought, whether the thoughts in my mind are the same, not to mention children and parents, even adults and parents may not be able to share the same frequency. Take the education of many families now, young people and old people have very different ideas. Most of the time, they just consider family ties and compromise by obeying filial piety. Children don't know much about the world, so naturally they don't think too much about adults' ideas. There is no problem in saying what they think and doing this.

Thirdly, if you want to share the same frequency, you need the family to create the same frequency conditions. When people have the same cognitive level and experience the same things, it is possible to have the same frequency. However, how many parents are willing to keep studying? The world is changing so fast that children are curious about the world and naturally rush ahead. But what about parents? Many people give up studying. How can this keep up with children's ideas? So I also mentioned at the beginning that the problem is the other way around. Why can't parents share the same frequency with their children?

Therefore, the solution to this problem is that parents should put down their posture, study and experience with their children, and not condescending. Children won't buy it.
