Do you receive the news of the intersection of time and space twice a day?

No, I won't receive the message of intersection of time and space twice a day, only 1 time. Space-time crossing "means that the mobile phone number and the mobile phone number of COVID-19 positive cases stay in the same signal grid (usually 800 m× 800 m) for more than a certain time. As long as there is an intersection with the trajectory of positive cases, whether it is a physical pass or a cell phone signal from the same communication base station, it will be considered as "intersection of time and space".
