How many days does it take to clear the record of the itinerary code?

The itinerary information generated by the itinerary code through big data communication will usually delete the previous itinerary records after 14 days. However, if the itinerary card shows that you have visited a medium-risk area, it may not be displayed until 14 days have passed. , there will be a delay of about one day during this period. Generally speaking, it will no longer be displayed after 15 days.

The itinerary code is not recorded every time you go to a place, but the time you stay in the local area. The conditions will be judged after four hours. If you stay in a certain city for less than four hours, the system will determine that you may have just passed by, such as driving or taking a train, and then it will not determine that you have ever been to this city. ?

The current rules of the stroke code:

The stroke code will be marked in four colors: green, yellow, orange, and red. This color rule changes dynamically. The current rules are:?

The yellow card represents: returning to China from overseas risk countries/regions within 14 days.
