Travel code 14 days will be updated. 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. On March 30th, the national government service platform "Epidemic Prevention Health Code" has integrated the relevant information of "Communication Big Data Travel Card", which can show whether the user has been to medium and high risk areas and other travel information in the health code, helping the health code to be "one code pass".
