What do you mean by low risk with an asterisk?

Low-risk means that your area is low-risk, and the * (asterisk) mark means that the user has been to the current medium-risk or high-risk areas of the city in the previous 14 days, but it does not mean that the user has actually been to these medium-high risk areas.

Expansion: Communication Travel Card, that is, Communication Big Data Travel Card, is a free inquiry service provided by China ICT Institute in conjunction with three basic telecom enterprises, namely China Telecom, China Mobile and China Unicom, through the location of the base station where the user's mobile phone is located. Mobile phone users can query all the city information they have visited in the previous 14 days through this service.

Query result rule

The trip calculation was completed in the background of the operator, and the result was delayed by one day. For example, the travel data calculated on March 5th is before March 4th 14 days (between February 20th and March 4th).

In addition, because the service uses base station data, in order to ensure continuous communication and achieve no blind area coverage, the base station signals at the junction of administrative divisions may cross-cover, resulting in deviation of the results, so it can be adjusted according to other certificates.
