When I went to Guangzhou from other places, I received a control call.

When citizens receive a call from Guangzhou police, a flashing message will be displayed on the screen, which reads: "China Mobile (Guangzhou Public Security) reminds: You have received a call from Guangzhou epidemic prevention and control, please pay attention to answering it." (This short message cannot be tampered with) The public can identify whether it is harassing calls or telecom fraud according to the content of the short message.

What is "tune"? In order to further improve the prevention and control of epidemic situation in COVID-19 and ensure the rapid and efficient implementation of epidemiological investigation measures in Guangzhou, Guangzhou public security organs and municipal and district disease control departments cooperated to carry out epidemiological investigation and resolutely curb the spread of epidemic situation. The so-called "epidemiological investigation", referred to as "epidemiological investigation", refers to the investigation of case exposure, activity trajectory and medical treatment, which can provide basis for judging close contacts, taking isolation measures and delineating disinfection scope.
