What is the intersection of time and space?

Time-space intersection means that my phone number and the number of the diagnosed person stay in the same time-space grid (the range is 800 m * 800 m) * * for more than 14 minutes, and the cumulative stay time of any number in recent 14 days exceeds 30 hours, and the found number is a time-space companion number.

My green health code will turn into a yellow code with warning nature, and will be marked as "time companion" by the system. For example, the infected person has been to a certain place within 14 days, and the trajectory of you 14 days intersects with him. Whether it is a physical passing or a drift in communication signals, it may be considered as a "time companion."

Post-processing method after receiving prompt information marked as "space-time companion"

First, immediately take the initiative to contact the community, unit or hotel, inform the news in time, and implement epidemic prevention and control measures such as nucleic acid detection as required, and do a good job in personal protection.

If you have symptoms such as fever, dry cough, stuffy nose, runny nose, fatigue, sore throat, and decreased sense of smell (taste), you should go to a medical institution in time and inform the doctor.
