Normally, the travel code will not change color when you pass through high-risk areas.

Whether you're traveling by highway or by train, you won't be judged as staying in the city for more than four hours, and you won't be recorded as flying over a city.

The "Big Data Itinerary Card" service is a public service provided by the three major telecom carriers that allows users to check the location of their trips, and can be used as a tool to prove that they have traveled. Efforts are being made to expand the reach of the service, but please follow the regulations of local governments, communities, and access points for specific access standards.

The above is about the highway through high-risk areas trip code will not change color of the introduction, under normal circumstances trip code only in a place to stay more than 4 hours will be recorded, and ride through the car is not relevant.

The trip card is able to check one's domestic and international trips within 14 days, accurate to the province or city (stay more than 4 hours) at home, and accurate to the country abroad.

That is to say, the card only records which provinces and cities you have stayed in, not whether you have been near a medium- or high-risk area.

It's only if you've returned from a foreign country within 14 days that you'll be marked with a yellow code, and only if someone has been diagnosed with a new crown or has been in close contact with a confirmed or suspected patient that you'll be marked with an orange code.

Besides that, all your trip codes will be green, no worries.
