What does the green code pop-up window of Xi mean?

It is a pop-up reminder attached to the health code that nucleic acid detection has not been carried out within the specified time. The health code will change from green to red and yellow depending on the situation. People with pop-up reminders need to go to the nucleic acid site for testing as soon as possible within 24 hours. After the test results come out, the pop-up window will automatically close, the code can be scanned and lit normally, and no reminder will pop up.
