Children, take care of these seven. First, put the used things back. It's a habit. Second, you can't interrupt others. This is respect. Third, you can't swear. This is quality. Fourth, say hello to your elders. First, this is etiquette. Fifth, apologize for your mistakes. This is a responsibility. Sixth, at least one sports hobby. This is health. Seventh, don't take other people's things indiscriminately. This is upbringing. Don't meddle with the children. Take care of these seven.
