1, let the children know that they can't be touched by strange uncles.
When children learn sex education, they will understand that others are not good to her and they are bullied. Therefore, they will avoid it in time when others want to touch it, and will not let criminals take advantage of it.
2. Give them a sense of crisis.
They have a sense of crisis, so they will not go to some small alleys with few people, but will go to places with many people. I will always pay attention to whether there are such people around me. They also don't meet online friends casually and go out to play with strange men during adolescence. They will also go home on time instead of staying up late. After all, people nowadays pay attention to their own safety, not to mention such a small child.
3. You can ask for help in advance.
When someone follows them or invites them to play together again, they will know that this is a sign that the other party is up to something bad, so they can ask people in the society for help or call their parents and ask them when to pick them up.
To sum up, universal sex education is very important. It can make criminals feel a sense of crisis, so as to retreat from difficulties.
