Will the trip code change when I return to Tongliao, Inner Mongolia via Chifeng Expressway on September 18, 2022?

The travel code passing through the epidemic area will not change color. Stay in a city for more than 4 hours before recording the travel code. If the travel time is less than 4 hours, it will not be recorded. The travel code is a code of the travel card for communicating big data, which is also equivalent to the health code. Health codes are based on actual data and can be generated by citizens or people who have returned to work through online declaration and background audit. The application scope of health code covers community management, resumption of business, transportation, starting school, drug purchase registration, supermarkets and shopping malls, which can help communities, enterprises and schools to do key work such as epidemic prevention management and epidemic control. Health code can realize efficient personnel flow management, improve the inspection efficiency of office buildings, shopping malls, subways, railway stations and other crowded places, and avoid excessive personnel contact and gathering.
