It's normal, during the epidemic in order to identify the close-knit people, a lot of people have received a survey called by the Epidemic Prevention and Control Center, as long as you've been to a medium to high-risk area, and then return to your place of residence, or elsewhere, the big data will be fed back to the government, but the big data is only the place you've been and the phone number, and then the Social Control Office will send someone to call you to ask you about your situation.

Generally, you will only be asked to provide information such as your ID number and your specific place of residence if you are in control or if you call to ask about the jurisdiction of your staff. In fact, if you don't feel comfortable, you will report yourself to the community, and you should do the nucleic acid for nucleic acid, and the home quarantine for home quarantine.
