China has been called "the country of culture" and "the country of etiquette" since ancient times. When it comes to the Four Books and Five Classics, we always think of an old gentleman with a five-foot pointer who says, "Who cares?" . That's the orthodoxy. Parents educate their children. The role between the educated and the educated often changes. The transformation of roles is a challenge to the traditional way of inheritance. We are always used to oral instruction because it is a tradition. This tradition has been tested by history and is the essence of the past. Suddenly, the teacher became an educated person, and the educated person became a teacher. Perhaps this is a subversion of tradition. Just like hip-hop music, the younger generation is immersed in its passion and randomness, while the elderly think it is absurd, meaningless and unacceptable. Existence is reasonable, and how many people are used to this kind of music and integrated into this kind of hip-hop, which adds many new ways to it. Therefore, in my opinion, the educated become our parents and we become teachers. The role transformation should also be realized slowly. The development and progress of science and technology is an important reason for the role change, I think. Imagine that in the distant ancient times, men plowed the fields and women worked. People have long been accustomed to this way of life, and it should be natural for parents to teach their children. Now, the times are different and the reality is different. Have the ancients seen mobile phones and used microwave ovens? Not to mention high technology. Our ancestors also came into contact with such tools very late, right? They must be surprised to see that the washing machine keeps turning and clean clothes appear soon. At this time, we need to help them and teach them how to use this high technology. In my opinion, the change of people's ideas is also the reason for the change of roles. With the continuous progress of the times, people's ideas have changed with time. Parents always pin their hopes on the next generation and teach their children the wishes that are difficult to achieve. They respect their children's personal development, which will naturally affect their parents' cognitive activities, thinking activities and behavior habits. As children grow up, parents will also be exposed to new things. To some extent, children are teachers and parents are students. Of course, this process is involuntary and active. Between role changes, we should learn good things and recommend things that conform to the trend of the times to our parents. Only in this way, teachers and students are interactive and two-way, and * * * is the driving force of the times to promote social progress. This kind of "feedback" is of great significance to us, our parents and society.
