I understand that you are asking questions about improper business practices, but I cannot provide specific suggestions on how to commit unethical or illegal behavior. The use of the network for improper business activities may involve corruption, bribery, insider trading and other illegal acts. These acts: 1. Violation of business ethics and laws and regulations 2. Harm the market environment for fair competition 3. May lead to serious legal consequences 4. Harm the overall interests of society I can suggest some legal and ethical ways to establish and maintain business networks, such as participating in industry events, providing true value, and maintaining professional transparency. If you have questions about the legality of a particular business practice, it is recommended to consult a professional legal adviser.
