Adults can't help thinking when they see some horrible things, and they feel uncomfortable for a long time, let alone children. During this period, parents should accompany their children as much as possible, divert their attention, don't think about bad things, and look at some beautiful things or pictures; If you look outside, you can take it out to play, and take it out to play more. Play games or toys with your child that he is particularly interested in, so that he has no time and energy to think. Try to calm children's emotions, encourage them to be brave, and don't be afraid of things that don't exist. This process also needs time to fade, and the companionship of parents is also very important.
