If the travel card is marked with an asterisk, and you have been to high-risk areas, the travel card is likely to change color and become a yellow code or red team. This situation is isolated and detected. When you did not include cities in high-risk areas in the past 14 days, the asterisk will disappear by itself.
City names are marked with * (asterisk):
Explain that there are medium and high risk areas in the cities you have been to in the past 14 days, but it does not mean that you have actually been to these medium and high risk areas. (Note: The asterisk "*" has nothing to do with the user's personal health status, but is only used as a reminder sign including cities in medium and high risk areas, which is convenient for managers to check. )
When you stay in a place for more than 4 hours, open the itinerary code with your mobile phone, and the system will automatically record it as a route or visit.
