In street conflicts, the core of using the environment for self-defense is to quickly create obstacles, distance and buy time to get out. The following are suggestions for operability, which need to be flexibly responded to in accordance with the actual situation： --- ###**1. Priority observation and prediction** 1. **Scan the environment**: Quickly look around and pay attention to fixed objects (lamp posts/railings/walls), movable objects (trash cans/bicycles/road cones), terrain (steps/vehicles/shop entrances), etc. 2. **Predict the line of movement**: If you cannot escape, choose an obstacle that can force the opponent to detour or change the angle of attack, such as： -**Avoiding around the column**: Use cylinders such as street lights and telephone poles to circle around the attacker and destroy its straight-line pursuit. -**Corner restriction**: Retreat to the right-angle wall, forcing the opponent to approach only from one side, reducing the risk of being besieged. --- ###**2. Application of obstacle classification** #### **A. Fixed obstacles** -**Guardrail/green belt**: Cross or detour horizontally to interfere with the opponent's balance. -**Glass windows/shops**: Close to storefronts with surveillance or flow of people, call for help loudly and slap the glass to attract attention. -**Vehicle**： -Use the front/rear of the car as a bunker to move around the car to maintain obstacles. -If the car is not locked, you can quickly enter and lock the door to call the police (pay attention to legal risks). #### **B. Throwing/moving objects** -**Trash can/roadblock**: Tear down and create stumbling obstacles, or grab the cover plate as a shield to block. -**Sand/gravel**: Grab and raise to the opponent's face (non-fatal but can buy time to get out). -**Bicycle/motorcycle**: Tear down the roadblock, or hold the frame horizontally in front of the body (keep your distance). #### **C. Terrain utilization** -**Steps/slopes**: Occupy a high place and defend with your legs, or induce the opponent to be unbalanced. -**Narrow alleys/passages**: When retreating, use your belongings (backpack/jacket) to wave horizontally to limit the opponent's approach. --- ###**Three, the key principles** 1. **Keep moving**: Avoid being forced into a dead end and always retreat to an open or monitored area. 2. **Make a sound**: Kick over the metal trash can and hit the wall with hard objects to attract the attention of the outside world. 3. **Legal red line**： -Use only defensive methods that are equivalent to the threat (such as the opponent's bare hands, avoid using knives). -Give priority to “passive obstacles” (such as avoiding around pillars) rather than actively and aggressively using items. --- ###**Four, psychological preparation** -**Calm observation**: Quickly assess the stability and availability of obstacles (such as glass doors that may shatter and hurt people, you need to be cautious). -**Bluffing**: Raise your mobile phone to pretend to shoot/call the police, which may deter the opponent. --- ###**Attachment: Response to high-risk scenarios** -**Multi-person siege**: With your back against a wall or vehicle, protect your head with a backpack/jacket, focusing on the defense of fragile parts such as the liver and ribs. -**Armed threat**: Immediately find a sturdy bunker (such as a stone pier/vehicle engine compartment) and keep the obstacle between yourself and the attacker. --- **Final reminder**: The core of self-defense is to get out of danger, not to defeat the opponent. Even if you successfully use obstacles to control the situation, you need to seize the opportunity to escape and call the police. Environmental sensitivity can be cultivated daily by observing the location of emergency exits and security facilities in public places.
