Parents must promise to reward their children, otherwise the children will steal their parents' money to satisfy their wishes. Parents should give their children some rewards appropriately, so that children can understand that they should learn to work hard. If parents don't reward children, children can't understand their parents' behavior. Parents must set a good example for their children. Some parents like to do petty theft in the supermarket, which will have a great influence on their children. Children will feel that this behavior is correct and will behave like this to their parents.
