How to isolate time and space in Dongying and Xicheng

Persons with yellow health codes and those with time and space risks who have received text message reminders from the Municipal Public Security Bureau and the Municipal Center for Disease Control and Prevention should report to the community immediately and undergo 2 nucleic acid tests within 3 days. The detection interval should be more than 4 hours.

Time and space companion means that my phone number and the confirmed number stay in the same time and space grid (range is 800M*800M) for more than 10 minutes, and the cumulative stay time of either party's number in the last 14 days For more than 30 hours, the number detected is a time-space accompanying number. My green health code will turn into a warning yellow code, and I will be marked as a "time and space companion" by the system. For example, if an infected person has been to a certain place within 14 days, and your trajectory in the past 14 days has intersected with him, whether it is a physical passing by him or a drift in communication signals, he may be identified as a "time and space companion." .
