In a conflict, it is the wisest choice to give priority to one's own safety and try to resolve the conflict through communication or leaving the scene as much as possible. If you have to defend yourself as a last resort, the following are some techniques based on human mechanics and defense principles. ** Only for knowledge sharing and should not be used for active attacks.**： --- ### **1. Destroy the core principle of the center of gravity** -**Center of gravity position**: The center of gravity of the human body is located near the belly button, and any movement that deviates from the support surface (the range of standing with both feet) can cause imbalance. -**Destruction of triangular support**: When the opponent is carrying weight on one foot or with both legs together (such as standing still or stepping momentarily), it is more likely to be pushed/pulled out of balance. --- ### **2. Practical skills (need to be combined with scene judgment)** ####**Push/pull class** -**Lateral thrust**: When the opponent steps or rushes forward, quickly push laterally to the side of the body (such as shoulders or hips), rather than pushing hard from the front. -**Pull-down imbalance**: Grab the opponent's wrist or collar and suddenly force downwards (in line with their own center of gravity sinking), forcing them to lean forward. ####**Lower limb destruction** -**Leg sweep (low-risk version)**: Use the ankle hook to sweep the inside of the opponent's ankle (non-vigorous kick), suitable for when the opponent is load-bearing on one foot. -**Step on the instep**: Quickly step on the instep of the opponent's front foot and push forward, which can restrict movement and destroy balance. ####**Joint control** -**Wrist lever**: Twist the opponent's wrist to the outside (such as the direction of “twisting a towel”), forcing the opponent's body to turn sideways out of balance. -**Elbow suppression**: Control the opponent's elbow to push in the opposite direction, so that it is forced to adjust its posture and cause the center of gravity to shift. ####**Clothing/environmental use** -**Collar/cuff control**: Suddenly pull the opponent's clothing and move with his footsteps to change the direction of his force. -**Environmental leverage**: Lead the opponent to the edge of obstacles such as walls and steps, and use the terrain to limit its support surface. --- ### **3. Precautions** -**Timing and speed**: Actions need to be quick and decisive to avoid dogfights. -**Self-stability**: Keep your knees slightly bent and lower your center of gravity to avoid being leveraged by the opponent. -**Law and Ethics**: Excessive use may cause serious injury to the other party, and the risk of liability is extremely high. --- ### **4. Safer alternative** -**Keep your distance**: Use your forearm to build a barrier and move sideways to avoid head-on conflicts. -**Deterrent posture**: Yell loudly to attract attention from the surroundings, while posing in a defensive posture (such as palms forward). -**Escape priority**: When the opponent's attention is distracted, quickly get out of contact. --- **Important note**: The above skills need to be practiced repeatedly under professional guidance in order to be used safely. True self-defense ability comes from preventive awareness, calm judgment and legal means. If conditions permit, it is recommended to learn self-defense or martial arts (such as Brazilian jiu-jitsu, Aikido, etc.) through formal channels.
