Shenzhen notified the quarantine, how to confirm the other party's information?

It doesn't involve money. The telephone number is the landline used by the District CDC, the area code is 0755 or 0086755, and the attribution is Shenzhen, Guangdong Province. District CDC will verify your identity information with you, including your address and ID number, ask if you have ever been to a certain place one day, and tell you that it is a secret contact and needs centralized isolation. You can pack your things and wait for community workers to contact you. According to the amount of information you have, the questions you ask are different. But I will never fill in the information of scanning QR code, and I will never involve financial, money and other information. "I will never ask for any information related to personal finance, such as bank cards, transfers, verification codes and other information."
