In any case, the priority is to avoid physical conflicts and resolve conflicts through communication or seeking help. If necessary for self-defense, the following are some balance-breaking techniques based on the principle of self-defense, but please remember: **Only for emergency self-defense, and must comply with laws and ethics**. --- ###**Core principle: Using mechanics and reaction** 1. **Destroy the center of gravity** -**Combination of push and pull**: Suddenly push the opponent's chest/shoulders forward, and then quickly pull back (using the reaction force of the opponent's resistance). -**Leg sweeping cooperation**: While pushing and pulling, use your feet to sweep laterally behind the opponent's knees or ankles (move quickly to avoid being caught by the leg). 2. **Principle of leverage** -**Wrist control**: If the opponent grabs you, quickly twist his wrist or elbow joint (rotate to the outside) to force his body to tilt. -**Shoulder pressure**: Use your forearm to press down on the opponent's shoulder from the side, and at the same time use your other hand to push the hip in reverse to form a rotating torque. 3. **Dynamic imbalance** -**Feint**: Pretending to move to one side, when the opponent's center of gravity shifts, suddenly reverse force (such as pretending to rush right, actually pulling left). -**Ground assistance**: If it is on slippery/uneven ground, the environment can be used to induce the opponent to step on the air. --- ###**Precautions** -**Legal risks**: Even in self-defense, excessive counterattack may lead to legal liability. Give priority to escape or call for help. -**Training necessary**: Untrained techniques may fail. It is recommended to learn formal self-defense techniques (such as Brazilian jiu-jitsu and aikido). -**Target selection**: Attacking joints (knees, ankles) or center of gravity support points (waist) is more effective than blind boxing. --- Please always take safety as your primary goal, call the police immediately after the conflict and keep evidence. True self-defense is to avoid injury, not to defeat the opponent.
