2. Not checked in other provinces: that is, the health code was not checked in other provinces.
3. Health code One is to report personal health, and the other is to master personal action track. For example, through the color of the health code, you can quickly identify whether a person has passed through provinces and cities with serious epidemics and whether he has directly or indirectly contacted infected people. Then through big data analysis, people who may be infected can be directly targeted and found. At the same time, every time the code is scanned to obtain the relevant health code, personal travel information will also be obtained by big data. If it shows that other provinces have not checked, it means the present stage (that is, 65438).
