How big is the generation gap?

3-5 years old. "Generation gap" refers to the differences in ideas, values and cultural concepts between people of different ages. People in China often say: "There is a generation gap at the age of three, but there is a gap at the age of five." It is because with the development of the times, the educational methods and contents are constantly changing. Two people with a difference of 3-5 years receive different education, which leads to their differences in knowledge structure and way of thinking, and this difference has caused a generation gap.
