In a fight or self-defense situation, the weak points of the body are mainly concentrated in the following areas: 1. **Eyes**: The eyes are very sensitive parts of the body, and attacks on the eyes can cause temporary blindness or severe pain. 2. **Throat**: The throat is relatively fragile, and attacks on the throat may cause suffocation or pain. 3. **Temples**: Impacts on the temples may cause loss of consciousness. 4. **Knees**: The knees are important joints that support the body, and attacks on the knees can cause the opponent to lose balance. 5. **Hips**: Attacking the hips can cause severe discomfort to the opponent and affect their ability to move. 6. **Ribs**: Attacking the ribs can affect breathing, which may cause pain and limited function. The goal is to quickly subdue the opponent, generally to achieve the following goals: 1. **Cause pain and interference**: By attacking the above weak points, the opponent is unable to move. 2. **Quickly get out**: In a self-defense situation, the goal is to protect yourself rather than engage in a long-term confrontation. 3. **Seize the opportunity**: At the moment when the opponent loses balance or is in pain, quickly implement follow-up actions, such as escaping or seeking help. It is important to remain calm and rational in any situation, try to avoid conflicts, abide by laws and regulations when taking self-defense measures, and ensure the safety of yourself and others.
