We often say that parents play an exemplary role in the family. We don't need to say too much, but we need to do it ourselves. Nowadays, many parents preach more and preach more, but they lead by example less. For example, some parents often watch mobile phones, and then ask their children not to watch mobile phones or TV. The actual effect is very poor, and there is a problem of going to school here. The biggest feature of family education lies in its teaching materials. Its textbook is family life, and we need to tap the educational value of family life, including eating, dressing and children doing their own things. These things are all a kind of education, and sometimes parents do it instead of children. For example, in order to hurry, parents try their best to help their children get dressed. It's called throwing watermelons to catch sesame seeds. In fact, family life itself is education, and parents' example is education. Some parents use school methods, just like teachers teach children, parents preach, and even hold a textbook. In fact, we need to explore the value and function of life.
