I think that this is a big problem for most parents. Maybe all of us have experienced that after working hard during a long day, we hoped that our children have done their homework alone without parents' help, but they just wanted to play with toys. When you criticized them, they responded with "Why can adults watch videos on their phones, but they have to study. Both parents and children had a long hardworking day. So, if we want to discipline a child, we need to discipline ourselves first. We need to set an example for them to follow. As parents, we always ask teachers to teach our children to be excellent. In fact, during most of the school time, children just gain knowledge from teachers. Their personalities are built at home or in society. Parents are the first teachers for their children. There is a saying that goes 'Phoenixes were born from phoenixes, and rats' children are able to dig holes innately.' If we do everything well, our children can also do everything even better!
