Travel cards are green, representing safety and health. If you go to high-risk areas, the travel card will be displayed in red. The query results show the visited provinces and cities (domestic), countries and regions (international). A * * * is divided into three cards: green, yellow and red, and the rules will be adjusted in real time according to the actual situation.
As long as it's a green code, it's fine. In travel itinerary, the names of cities in high-risk areas will be marked in red, which is only used as a travel reminder and has nothing to do with health status. Please follow the joint prevention and control mechanism of all localities for specific control policies.
