What does it mean to receive a yellow message?

Receiving this message means that you need to do accounting and testing.

Generally speaking, when the health code is given a yellow code, the prefecture-level city will send a reminder message to the crowd with the yellow code. If you receive the message of nucleic acid testing, if you do the nucleic acid testing as required, the result will be deleted from the yellow code list and will not become yellow code.

The yellow code refers to people who have had time and space overlap with confirmed cases or asymptomatic infected people, and there is a risk of infection. Therefore, the yellow code is a reminder to those who are in danger. If the travel code turns yellow, there is no need to panic excessively.
