1. Ask the other party to show relevant certificates or certificates, such as work permit and law enforcement certificate.
2. If the other party claims to be a staff member of the Industrial and Commercial Bureau or other law enforcement agencies, he can call the agency to verify whether his identity and requirements are true.
3. If in doubt, you can consult the local industrial and commercial bureau or relevant institutions to find out whether there are similar requirements or actions.
Please note that if the other party asks you to provide personal information or pay fees without showing any certificates or certificates, it is probably a scam. In this case, please do not easily provide any personal information or pay any fees, but immediately call the police or seek help from relevant institutions.
