1. Communication and negotiation: First of all, you can communicate with the security guard, explain your actions and intentions, and express your respect for the regulations of the community. In communication, you can ask the specific reasons and basis of the security guard's blocking, find the crux of the problem, and try to reach an understanding.
2. Understand the regulations: If the security guard's blocking behavior is based on the relevant regulations or policies of the community, then you can carefully understand these regulations or policies to ensure that your behavior meets the requirements. If you find that your behavior violates the regulations, you can stop and apologize.
3. Seek help: If communication with security guards fails to reach a consensus, you can try to seek help from property management companies, owners' committees and other relevant departments. They will provide more professional guidance and mediation to help solve problems.
4. Legal channels: If the above methods fail to solve the problem, you can consider protecting your rights and interests through legal channels. You can consult a lawyer to understand relevant laws and regulations and take corresponding legal actions.
