The health code is marked with an asterisk, which means that there are high-risk areas in the city, but it doesn't mean that you have been to high-risk areas.
Travel card asterisks generally disappear.
When you did not include cities in high-risk areas in the past 14 days, the asterisk will disappear by itself.
Travel card asterisk marks the update time. The asterisk marks will change according to the identification of high-risk areas in cities by epidemic prevention departments, and the data will be updated according to the latest information released by local health and wellness committees. There will be a certain time difference in data update, and synchronization will generally be completed within 24 hours.
