It has been 9 days since the trip code, and it still shows the reason.

Travel itinerary code is still displayed after 9 days, which is generally caused by no update. You only need to review it again to update the itinerary, and the update will be delayed for one day.

The travel code stays in the same province and city for more than four hours, and the location of the mobile phone travel code is updated. The communication travel card can be used to inquire about personal travel within the first 14 days at home and abroad, and the cities visited before 14 days are not displayed. If the travel code has been scanned for 14 days, and this field is still displayed, it is usually not updated. You only need to watch it again to update your itinerary.
