The message sent by 100 10 has appeared at the epidemic scene. What happened?

After receiving the text message, you can still travel, but you need to do nucleic acid testing twice within 72 hours according to the requirements of the text message. During the period, on the premise of personal protection, travel simply (avoid taking public transport and go to crowded places). Friends who have done a nucleic acid test these two days will meet the requirements if they do it again every 24 hours. The results of two nucleic acid tests are normal, and you can return to your normal life.
