The itinerary code is green but has an asterisk, which generally does not affect travel. There is an asterisk on the itinerary code, indicating that the city the user visited in the past 14 days is currently a medium-risk or high-risk area. However, it does not mean that the user has actually visited these medium- and high-risk areas, so the green itinerary code with an asterisk will basically not affect travel.

The communication big data itinerary card uses the "signaling data" of mobile phones to obtain it from the base station location of the user's mobile phone, providing free query services to mobile phone users. Mobile phone users can use the service to query information about all cities and towns they have visited in the past 14 days.
