How can I receive SMS notification if I haven't been to key places?

If you haven't been to a key place, report to the community, neighborhood Committee, unit or hotel where you live before receiving the SMS notice. Put on a mask and immediately go to the nearest nucleic acid testing institution (you can check it in Chengdu Guanwei) for nucleic acid testing. Don't take public transport on the way. Don't go out and stay at home until you get a negative result.
