How long will there be a pop-up window when time and space intersect?

Five minutes. Time-space intersection is a technical term of public security and telecommunications departments. Space-time intersection and space-time accompaniment are the same concept, which means staying in the same space-time grid (800 m× 800 m) with the diagnosed patient within 14 days 10 minutes. If you don't get the message right away, there will be a slight delay and a pop-up window will appear in about 5 minutes.
