Not in Harbin, but what happened to the message sent by the general manager of Harbin epidemic prevention?

You may have had direct or indirect contact with infected people in COVID-19 recently, and there is a certain risk of infection. Every citizen has identity information which is recorded in the computer system. As long as your mobile phone has Internet, you will receive all kinds of information. It is everyone's responsibility to prevent epidemics. Even if you don't receive a text message, you should do a nucleic acid test every day or every other day.
