When encountering an emergency danger in a public place, the rational use of surrounding objects for defense needs to follow the principles of legality, necessity, and moderation. Here are some suggestions (but please give priority to fleeing danger and seeking help)： --- ###**Basic principles** 1. **Legal risks**: Any defensive behavior must comply with local laws, and excessive injury may constitute an offense. 2. *****: Only use when life and safety are threatened to avoid active attacks. 3. **Clear goals**: Give priority to attacking vulnerable areas (eyes, throat, crotch, etc.) to buy time to escape. --- ###**Defense methods for common items** #### 1. **key** -**Usage**: Hold the key between your fingers (tip outward) to poke the opponent's eyes, throat, or face. -**Note**: To avoid hurting yourself with the key by making a fist, you can use a single long key to have a better effect. #### 2. **Pen/ballpoint pen** -**Usage**: Hold the pen holder tightly and quickly stab the opponent's hand, neck or inner thigh with the tip. -**Advantage**: Strong concealment, can be carried with you. #### 3. **Umbrella/umbrella with long handle** -**Usage**： -**Poke**: Stab the opponent in the abdomen or throat with the tip of an umbrella. -**Block**: Wave the umbrella horizontally to interfere with the opponent's line of sight or hit the joints. -**Pull away**: Spread the umbrella as a shield to block the attack. #### 4. **Backpack/handbag** -**Usage**： -*****: A backpack full of items can hit the opponent's head or body. -**Block**: Hold it in front of you to resist attacks with knives or sticks. -**Throwing**: Throw at the opponent's face to buy time to escape. #### 5. **Belt** -**Usage**: Untie the belt, hold the buckle end in your hand and wave a whip (similar to a soft whip) to attack the face or armed hand. -**Advanced**: Wrap the opponent's arm or neck with a belt (certain skills are required). #### 6. **Hot water/hot drinks** -**Usage**: Splash hot water on the opponent's face (especially eyes) to create an opportunity to escape. #### 7. **Books/magazines** -**Usage**: Roll into a cylinder and hit the opponent's temples, bridge of nose, or throat, or spread out a book to block the opponent's line of sight. #### 8. **Mobile phone** -**Usage**: Hold the phone tightly and hit the opponent's temples, nose bridge, or wrist with the corners and corners (available in an emergency). #### 9. **coin** -**Usage**: Grab a handful of coins and sprinkle them on the opponent's face to interfere with the line of sight, or hold them in your fist to increase the strength of the blow. #### 10. **Perfume/hair spray** -**Usage**: Spray into the opponent's eyes to temporarily blind them (pay attention to downwind use). --- ###**Safety tips** 1. **Priority escape**: The purpose of defense is to buy time to escape, not to subdue the opponent. 2. **Stay calm**: Observe the surrounding environment and look for exports or available items. 3. **Avoid provocation**: Unless it is impossible to avoid, do not actively intensify the conflict. 4. **Post-mortem treatment**: Call the police immediately after exiting the danger, and keep evidence (such as surveillance video). --- ###**Important supplement** -**Prepare in advance**: You can learn basic self-defense techniques (such as breaking free skills, joint countermeasures) on a daily basis. -**Legal boundaries**: Defense must be equal to the degree of infringement, and excessive counterattack may be deemed intentional injury. Please remember: **The best defense is to prevent risks**, such as avoiding walking alone late at night and paying attention to your surroundings. It is recommended to take regular self-defense courses (such as Israeli maga) to improve resilience.
