Learning how to use obstacles in your environment for self-defense is an important part of improving your personal safety in dangerous situations that you may encounter on the street. However, it is important to emphasize that the primary goal of self-defense is to protect yourself and avoid escalation of conflicts as much as possible. Here are some suggestions to help you effectively use your surroundings for self-defense when necessary: 1. **Maintain environmental awareness**: - **Observe your surroundings**: Always pay attention to your surroundings, including potential exits, obstacles, crowded areas, etc. - **Identify obstacles**: Be aware of objects around you that may be used as defenses or partitions, such as trash cans, benches, vehicles, railings, etc. 2. **Use space and distance**: - **Create distance**: Use obstacles such as street railings, vehicles or buildings to increase the distance from the opponent and reduce the opponent's attack range. - **Divert the route**: Use obstacles to change the route of travel, avoid direct contact with the opponent, and find a way to escape. 3. **Use objects as barriers**: - **Temporary protection**: Use objects you carry with you (such as bags, umbrellas) as temporary barriers to block the opponent's attack. - **Blocking vision**: Use obstacles to block the opponent's vision, temporarily confuse the opponent, and buy time for escape. 4. **Using height differences in the environment**: - **High position advantage**: If there are high places around, such as steps, pillars, etc., you can use these positions to gain a visual advantage and observe the opponent's movements. - **Low position protection**: When necessary, you can lower the center of gravity and use uneven ground or obstacles for defense. 5. **Flexible use of escape routes**: - **Preset routes**: Familiar with the main escape routes around to ensure that you can evacuate quickly in an emergency. - **Avoid obstacles**: During the escape process, flexibly use obstacles to avoid the opponent's pursuit and ensure your own safety. 6. **Legality and safety**: - **Understand the law**: Before using any items for self-defense, understand local laws and regulations to ensure that the self-defense behavior is within the scope permitted by law. - **Avoid excessive defense**: The purpose of self-defense is to protect yourself and avoid using excessive force to cause unnecessary legal disputes or harm others. 7. **Training and preparation**: - **Self-defense courses**: Take professional self-defense training courses to learn how to effectively use the environment for self-defense in emergency situations. - **Simulation exercises**: Through simulation exercises, familiarize yourself with how to quickly identify and use obstacles for self-defense in different environments. **Important tips**: Although it is important to understand how to use the environment for self-defense, the best self-defense strategy is to avoid dangerous situations. Stay calm and try to defuse conflicts through words or body language, and avoid physical confrontations as much as possible. If the situation gets out of control, prioritize escaping and seeking help.
