Why does Qinhuangdao Health Treasure show abnormal itinerary?

Medium or high risk areas were visited. The city where Qinhuangdao Health Treasure Travel Card is located or passes through is marked with an asterisk, indicating that there are medium-risk or high-risk areas in the cities visited in the past 14 days, but this does not mean that you have actually been to these medium-high risk areas. 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 a visit. When the trip of the past 14 days does not include cities in high-risk areas, the asterisk will disappear by itself.
