"Big Data Route Map" 通信大数据行程卡, also known to the general public as "Route Code" 行程码, is operated by the Ministry of Industry and Information Technology of China and jointly launched by China Information and Communication Technology Academy, China Telecom, China Mobile and China Unicom. The non-commercial route request service can provide users with confirmation of the provinces (regions) and cities of the country they have visited in the past 14 days, free of charge.
Currently, users of any of the three operators China Telecom, China Mobile and China Unicom can use the service. However, new map users can use the itinerary help service after 14 days.
The information displayed on the "Communication Big Data Route Map" includes: the user's encrypted mobile phone number, the route information update time, the color map, all the countries (regions) that the user has visited in the past 14 days, and the country's cities remaining over 4 hours, as well as cities in medium and high risk areas.
So, what does the asterisk "*" that now appears on route maps mean?
According to the "Big Data Communication Route Map" user manual, the mark "*" in the upper right corner of the visited place indicates that there are currently medium or high risk areas in the city, and does not mean that the user has actually visited these medium and high risk areas. high risk.
It should be noted that the asterisk "*" has nothing to do with the user's personal health condition, but is only used as a hint for medium and high risk areas, which is convenient for management personnel to check.
When a user's route in the last 14 days does not include cities in the medium and high risk areas, the asterisk will disappear by itself.
The asterisk will change depending on the location of the visit determined by the Epidemic Prevention Department. Usually, the asterisk for medium and high risk areas is updated within 24 hours according to the latest information published by local health commissions.
In case of disagreement, it is recommended to contact the relevant epidemic prevention department and determine your own route based on personal travel documents, residence documents, public information, etc.
