1. We should always tell our children some simple truths to make them realize that there are both good people and bad people in society. There is no word "I am a bad person" on the faces of bad people, and there is no image of bad people in movies. To educate young children, if adults are not around, strangers will pick you up, or go to the park with you, or when you go to your parents' house, don't believe what strangers say, don't walk with strangers, and don't eat strangers' food. If you are dragged away by strangers, make a hullabaloo about to your uncles and aunts.

2. Let the children know their home address, parents' names and work units, and repeat them, remember them firmly and be accurate. In addition, tell children what obvious signs are near their home and which buses they can reach. In case of getting lost, it is easier to find their parents and get home safely in time.

3. Tell your child that if a stranger follows you, you should run to the nearest store to ask an adult for help, or you can ask the police for help, or you can just find a family and pretend to shout "Mom and Dad, I'm back" at the door, and the bad guys will scare away.
