Based on the cell phone number, you can check. The big data of the communication trip card can be searched through my WeChat search "communication trip card" small program query, but also by scanning the WeChat small program QR code query. If a person from a low-risk area stops in a medium- or high-risk area for more than four hours, the status of the BHB and the Communication Big Data Itinerary Card will change, so please plan your trip wisely.

If you are just passing by train, do not get off the train, do not get out of the station, the trip code will not be affected by passing by, if it is at the airport over the station, stopover, transit passengers and crew, such as not out of the terminal isolation and control area will be affected. On the contrary, whether by train or airplane, or self-driving situation, as long as direct contact with the high-risk areas will have an impact, will be the first time to take epidemic prevention measures.
