I got a message from red team, but it didn't turn red.

Verify where you see it sent to you, and then open the health code of the corresponding province to see if it is a red code. The operation method is to open the Alipay health code, with a city name in the upper left corner, and click to switch the corresponding city in the short message (at the beginning or end of a normal short message, which institution sent it, such as the epidemic prevention and control office of a province or city). It's still a green code after switching. You can check whether there are any reasons for the red code mentioned in the short message, such as close contact, inter-provincial travel, and going to medium and high-risk areas. The actual situation also exists and needs attention. You can contact the local prevention and control consultation.
