When returning to Beijing, the nucleic acid must be done within 72 hours (note that not only the nucleic acid is done within 72 hours, but the most important thing is that the nucleic acid results within 72 hours should be uploaded to Beijing Health Treasure, otherwise the nucleic acid will be done within 72 hours, and a pop-up window will pop up if the results are not uploaded in time).
If you don't leave Beijing that day, you can wait until the next morning for the system to update automatically, and then use Beijing Health Bao for self-examination, and the pop-up window will be automatically lifted. If you do nucleic acid on Beijing Health Treasure, you can check the people who left Beijing that day. You can go to the neighborhood Committee (find a property without a neighborhood Committee) to report your situation. The neighborhood committee or the property will push the information to the CDC in this district and update it at noon 12 every day. At this time, it is normal to ask about Beijing Health Treasure.
