In an emergency, if you need to quickly subdue the opponent, the first thing to emphasize is that protecting your own safety and avoiding violence as much as possible are the most important. If you have to take action, here are some suggestions: 1. **Understand the environment**: Quickly observe the surrounding environment and find objects or facilities that can be used, such as tables, chairs, etc., which can be used as barriers or weapons. 2. **Find support**: Maintain a good center of gravity and avoid standing unsteadily so that you can move or react quickly. 3. **Sniper weak points**: Some sensitive areas of the human body such as eyes, throat, abdomen, knees, etc., appropriate attacks on these places can quickly subdue the opponent. 4. **Use control techniques**: If you have the relevant skills, you can try to use control techniques such as joint locks and strangulations to control the opponent. 5. **Use your body weight**: If you are heavier, you can use your center of gravity to suppress the opponent, ensure that you remain stable and suppress the opponent. 6. **Seek help**: If the situation allows, shout for help or find people around to help solve the problem. 7. **Stay calm**: Stay rational, quickly judge the situation, and choose the best response strategy. Remember that buying time and space to escape danger is the best strategy. If possible, try to draw attention to safe escape. In any case, physical confrontation should be the last resort. Personal safety and respect for the lives of others are always the most important.
