From 20: 30 on 202118, the city name of the medium-high risk area is no longer marked in red on the travel card, but is marked in brackets after the city name. Precautions are only used as travel tips and have nothing to do with health status.
Extended data:
The communication big data travel card takes whether the user stays in the local area for 4 hours as the main criterion. For this time, Beijing only designated the risk area to a specific building, but the specific reason why the word "Beijing" turned red is not clear, let alone the further relevant requirements of the higher authorities.
In this epidemic in 2020, the communication big data travel card played a very positive role and achieved the purpose of dynamically monitoring personal travel. However, in reality, the division of risk areas is becoming more and more detailed, and the standard of communication big data travel cards is still generally administrative units such as prefecture-level cities, with a large delineation range and a slightly backward monitoring method. There is still room for further improvement and refinement in the future.
