1. Be strict with yourself, restrain your behavior, don't go to bars and other places that are difficult to get in and out, and avoid getting drunk and coming home late occasionally. 2. A threesome can be a teacher, that is to say, girls should make friends when they go out, avoid damaging friends, and avoid misguided victims. 3. Pay attention to your privacy and don't easily expose your personal information such as your address and contact information to strangers or institutions. 4. Learn more about or prepare some emergency help methods, such as finding someone to accompany you late, remembering the phone number of the community security guard, and preparing some emergency protective equipment at home. 5. Make a satisfactory boyfriend. After all, it is not safe for a girl to be away from home for a long time. If you have a boyfriend, you can guard at any time to improve your sense of security and avoid unexpected situations. 6. Keep in touch with parents, family or friends at any time. Think about it. If something happens to you suddenly, your family will be the most anxious people and you will not be contacted. Only your family will always care about you and show up when you need them most.
