When defending yourself in public, the most important thing is to improve your personal safety awareness and take precautions. Here are some suggestions: 1. **Stay alert**: Always pay attention to your surroundings and avoid distracting yourself with your phone or headphones. Know the exits and safe places around you. 2. **Confidence and attitude**: Show a confident attitude and avoid appearing weak or vulnerable. A firm look and clear body language can scare off potential threats. 3. **Use your voice**: When you feel danger, shouting or asking for help can attract the attention of others and scare off attackers. 4. **Learn self-defense skills**: Take formal self-defense courses to master some basic self-defense movements and strategies to improve your ability to deal with emergencies. 5. **Carry self-defense tools**: According to local laws and regulations, consider carrying legal self-defense tools such as anti-wolf spray, whistle, etc., and learn how to use them correctly. 6. **Trust your intuition**: If you feel that a place or situation is unsafe, leave or seek help in time. 7. **Avoid potential dangers**: Try to avoid going to remote or sparsely populated places alone, especially at night. Through the above measures, we can effectively improve our self-protection ability in public places and reduce potential dangers.
