Do you want to call the students who come back from Guangzhou to inform them that the nucleic acid test has not come?

Yes Guangzhou, referred to as Guangzhou for short, is the capital and sub-provincial city of Guangdong Province. Nucleic acid detection is a direct virus detection method, which obtains results by "grabbing" the genetic material inside the virus. Students who come back from Guangzhou inform residents that they missed the nucleic acid test, so they can call the residential property to explain the reasons, and the property will contact volunteers to understand the situation.
