What kind of office work do you belong to in the same building as the confirmed patient?

Brief introduction of "Time Companion":

"Space-time companion" has no unified explanation and no fixed name. There are different opinions in different places, and the aliases are "intersection of time and space" and "coincidence of time and space". Not all people who appear at the same time will be identified as "time and space companions." To meet this condition, we need to judge from the following two aspects.

1. Both sides appear in the same space, with a distance of 800 m * 800 m; There are also requirements for the stay time, 10 minutes or more.

2. The confirmed patient has been to that place within 14 days, which is a coincidence of time and space. Such a situation will also be recognized as a "time companion"

If you receive a short message and are judged as a "time companion", you should stop outdoor activities immediately. Report to local epidemic prevention personnel and receive nucleic acid testing at home.
