On December 27, Xi'an began a new round of nucleic acid testing. In a construction site in Xi'an, 158 workers and 41 managers were "stayed" on the project for closed management.

In order to avoid the risk of infection caused by the gathering of people, after coordination, two nucleic acid detection points were set up on the project site. One provides nucleic acid sampling for “stranded” workers and management personnel, and the other provides nucleic acid sampling for nearby people.
