How does the community know where you have been?

The community knows where you have been, which may be obtained through the following channels:

1. Big data. In the era of big data, everyone's travel may be recorded. When you use your mobile phone to make phone calls, send text messages, surf the Internet and other activities, the mobile phone will automatically connect to the signal base station. The information of these base stations is held by the three major operators, so you can record your itinerary information.

2. Community registration. If you are a resident of this community, there may be your information in the computer system of the community neighborhood Committee, and you can see some of your whereabouts through big data retrieval.

It should be noted that no organization or individual may view or use other people's travel information without the consent of the parties concerned.
