Is it necessary to isolate the green code with stars to Jiande?

According to relevant information, query display is not required. Because the travel itinerary code is green but marked with an asterisk, it means that there are medium and high risk areas in the cities you have been to within 14 days (staying in a place for more than 4 hours), it doesn't mean that you have actually been to these medium and high risk areas. The asterisk on the itinerary card is only a reminder and has nothing to do with personal health. Travel itinerary has a green code with an asterisk. If you are sure that you have never been to a medium-high risk area, you can travel normally without isolation, but it is recommended to hold a 48-hour negative nucleic acid certificate before going out. If you go to a high-risk area, you need to be quarantined 14 days.
