Receiving SMS reminders from the Epidemic Prevention and Control Office indicates that you may have been in contact with a new crown-positive case or passing through a medium- to high-risk area.
Don't panic, report it to your community, avoid going out unnecessarily for the time being, and actively cooperate with the nucleic acid test. If it is verified that you have not been in contact with any of the new crown positive cases or medium to high-risk areas, and the nucleic acid test is negative, then you can go back to your daily life.
