What do you mean by the same trajectory of the epidemic?

It means to go to the same place with people in danger at the same time. Went to the same place, so it was called the same track. In other words, it is possible to reach high-risk groups.

To understand the trajectory of your own epidemic, you should do personal protection during the trip and don't contact outsiders or things. Foreign vehicles should keep a distance of two to eight meters from strangers or familiar people.

If foreigners have opened a domestic mobile phone number in China, they can use the mobile phone number to check the running track in China 15 days. This method is the same as domestic tourism. If you don't have a cell phone number. If necessary, go to the local government and community for the record. Describe the place of travel and transportation. Issue travel records, including air tickets and plane tickets. Accommodation and other related information. After foreigners enter the system, they can check the movement track through the system when they check into the hotel.
