Can I fly when I receive the message of time and space crossing?

Expert's response: It is required to report to the community after receiving the "time-space cross" message, complete the nucleic acid detection twice in three days as soon as possible, and do a good job of self-health monitoring in 14 days. During this period, public transport is not allowed.

The concept of "space-time intersection" is the same as that of "accompanying space-time", which refers to the person who stays with the diagnosed patient for 14 days and * * * stays 10 minutes in the same space-time grid (usually 800 m× 800 m as the detection range). In layman's terms, for example, an infected person has been to a place within 14 days, and the trajectory of your 14 days intersects with him. Whether it is a physical brush or a drift in communication signals, it may be considered as a problem of time and space. Experts said that screening "time-space companions" can find potential risk groups to the greatest extent, and include more people who are "time-space overlapping" and may be infected in key investigations, so as to truly achieve early detection and early prevention and control.
