Is it legal to contact me to answer the phone when reporting the Chongming market supervision?

When reporting, the market supervision and management department will try its best to protect the personal information and safety of the reporter, and usually will not ask the reporter to provide personal contact information. However, if the market supervision and management department needs to further verify the report information, it can contact the reporter for investigation and certification, and then the reporter needs to provide legal contact information. At the same time, the reporter can choose to report anonymously, which can protect personal information and security.
