Why does the child’s itinerary card fail to be verified on the adult’s mobile phone?

Data is not logged.

The failure to obtain the trip code may be because the data is not recorded or the network is not good.

Beijing was not filled in during the itinerary verification. This is because people entering and returning to Beijing only filled in non-Beijing areas when filling in the places they visited during the 14 days. The itinerary is not filled in completely and does not match what is shown on the itinerary card. This is due to insufficient accuracy in filling in the places visited in the 14 days.
