Generation gap refers to the differences in ideas and behavior habits when children abandon their parents' original views and gain new ones in the process of going to society. The generation gap is often formed because of great differences in age or times. The world of children is completely different from that of adults. Ignorance will seriously affect children's development. People of different ages live in different circles and come into contact with different things and people, so their ways of thinking and behavior are also different. If this difference is not improved and allowed to expand, an invisible wall will be formed between the two generations, which is easy to misunderstand. This is the psychological generation gap. To paraphrase a modern language is the so-called "generation gap".
