Stay in the same place for a long time. Spatio-temporal intersection means that within 14 days, the telephone number of residents and the telephone number of a confirmed patient or asymptomatic infected person stay in the same spatio-temporal grid (the range is 800 m * 800 m) * * for more than 10 minute, and any number stays in this area for more than 30 hours in recent 14 days. The number found is the intersection number of time and space.
