The asterisks in the health code generally refer to the green color of the health code but the asterisks in the trip code refer to the presence of medium or high risk areas in the cities that you have traveled through or visited in the past 14 days. "Via" means staying at a place for more than four hours and using a cell phone to open the code, which is automatically recorded as passing through or visiting, but does not actually mean that the medium- or high-risk areas were actually visited.

Health code with an asterisk generally have the following two ways to lift:

1, 14 days after the disappearance of their own: this time is related to the user's own time, and has nothing to do with the risk areas, if the asterisk in the trip card still exists after 14 days, then it is recommended that you can adjust by calling the communication service provider related to the communication trip card.

2. Risk areas: If the risk level of the associated risk area is adjusted to low risk, then the asterisk on the trip card will automatically disappear.
