The trip code through the big data communication to make the trip information, usually after 14 days will eliminate the previous trip records , but if the trip card shows that it has been to the medium-risk areas, it may be after 14 days before the day will be displayed, during the period of time there will be about a day or so of delay, in general, after 15 days no longer show.

The trip code is not recorded for every place you visit, but for the time you are stationed there, and four hours will judge the conditions. If you stay in a city less than four hours, then the system will determine that maybe you just passing through, such as driving or taking the train around just, then this time will not determine that you have been to the city.

The current rules for trip codes

Trip codes are marked with four colors: green, yellow, orange, and red, and the color rules change dynamically. The current rule is: ?

Red color stands for: confirmed or suspected patients with new crown pneumonia (data source: Health Commission);?

The orange card represents: close contacts of confirmed or suspected patients with new crown pneumonia;?

Yellow card represents: returning home from overseas risk countries/areas within 14 days;?

If there is an outbreak in your city and there is an intermediate or high risk area, the travel card will not change color, it will just be represented by a "*".?
