The first point is to tell children not to associate with strangers and not to listen to strangers easily. This is very important, because most people have moved to cities now, and in the urban environment, neighbors rarely know each other. The people here are very complicated and don't know anyone, so there are often many strangers.
Something went wrong in this case. The child was taken away by a stranger. I don't know if I can find it. Therefore, children must be warned to know how to protect themselves, not to communicate with strangers, and not to talk to strangers, because no one knows whether they have an evil heart. If they want to hurt their children, and the children are so small and particularly vulnerable to being deceived, it will be very dangerous.
Secondly, children should be warned not to play in dangerous places. There are many kinds of dangerous places, such as under houses that are prone to collapse, or places with high gaps and water. Especially near the water, many children especially like to play with water. When they walk together, they are brave. One of them may suggest going to the water's edge to play, and he also said that those who don't go to the water's edge are cowards, and then all these children will go down, which is very dangerous at this time.
In addition, children should be told to ask others for help when they are in danger, not to do it themselves, and to ask the police uncle or others for help when they are held hostage by strangers. They can make a hullabaloo about to attract others' attention, or run to tell the traffic police on duty, or go to the police station to call the police.
When you are outside, you must also go together and spend more time with your friends. It is easy for dangerous people to target children when they are alone.
