The Prevention and Control Center called and asked what occupation meant

It is for flow adjustment.

The transfer personnel first verify whether the content on the assistance letter is accurate, whether the person is local and at the specific location. If you are in the local area, continue to ask for the transferred person’s basic information (occupation, ID number, current address, workplace, etc.) and the date of arrival. Next, we need to track down the movements and specific times in recent days, who we have contacted, where we have been, people we travel with, people we live with, and all other people we may come into contact with. If the transferred person is not in the local area, his current location must be inquired, and a report will be sent to the Provincial Center for Disease Control and Prevention in a coordinating investigation letter to the local disease control department for co-investigation. If the target of the investigation does not cooperate, the investigation letter will follow the person's trajectory until the person is found and controlled.

Recently, many scammers will pretend to be personnel from the prevention and control center and call them, so pay attention to screening.
