How to help parents change the old educational concept in the past?

It is difficult to help parents change their old educational ideas. After all, my parents are quite old now, and their education level may not be very high, and they have been influenced by old ideas for a long time. This concept has been deeply rooted in their minds, and it is difficult to make changes when they are old, but it does not rule out that some parents are more receptive to new ideas, as long as the way is correct:

1, influenced by parents of the same age, accepted the ideas of foreign parents and changed their views.

2, accept the influence of TV, Internet and other media, and guide them to change their ideas.

3. Talk to your parents calmly and change your parents' thoughts with theories and examples.

No matter which way, personally, it is not simple, and it takes many times or even many methods to achieve the goal.
