It is not annoying to send travel codes every day.

Travel code, that is, communication big data travel card, is a free inquiry service provided by China ICT Institute in conjunction with China Telecom, China Mobile and China Unicom for Chinese mobile phone users by using communication big data. Mobile phone users can query all the city information they have visited in the previous 14 days through this service.

The epidemic situation is still very serious. The importance of a full schedule today is self-evident. It can record the distance you have traveled. By analyzing the trip code, judge whether you have passed through a high-risk area to show other colors.
