Why do other areas show that I am a green code, and Beijing Health Bao shows that I have time and space connections?

Which means I'm likely to be marked as a time companion.

If the health code suggests that I have a time-space intersection, it means that I am likely to be marked as a time-space companion. Space-time companion number means that my phone number and confirmation number stay in the same space-time grid (the range is 800 m * 800 m) for more than 14 minutes, and the cumulative stay time of any number in the last 14 days exceeds 30 hours, so the number found out is the space-time companion number.
