The city name marked with * (asterisk) indicates that there are medium and high risk areas in the cities you have visited in the past 14 days, but this does not mean that you have actually been to these medium and high risk areas. Although the green travel itinerary with an asterisk will basically not affect travel, we still encourage everyone to minimize unnecessary walking and unnecessary trips to high-risk areas.
Precautions for trip codes:
Communication Big Data Travel Card is a travel inquiry service jointly launched by China Telecom, China Mobile, China Unicom and China ICT Institute, which can provide users with free travel certificates of countries (regions) and domestic cities they have visited in the past 14 days.
In order to facilitate users to inquire and prove the health status of epidemic prevention, the national comprehensive government service platform has now incorporated the information of communication big data travel card into the epidemic prevention health code service.
