The health code does not display the trip originally, but the trip code does. If you find that the trip code can't be brushed, check whether the distance from 20 o'clock is more than 4 hours at the first time. If it exceeds, call someone immediately, preferably for more than 3 minutes. If not, try again the next day. 1 day, it is best to have 5 calls, with an interval of 1 hour or 1.5 hours. Before 20: 00 on the same day, the interval between the first call and the last call exceeded 4 hours. Reason why the health code does not display the trip:
1, because this area is the hardest hit area, no health code will be issued.
2. Temporary health codes will not be displayed during closed management.
3. The specific sending time needs to be notified by the local epidemic command.
4. Check your own network. If the network is poor, it cannot be displayed. 5. Check your information, because your information is wrong.
