What is the short message received in Huang Ma?

The short message received by Huang Ma will show that you should stay at home. Guangzhou SMS requires two tests every three days, and two nucleic acid tests must be carried out within three days, and the interval between the two nucleic acid tests must be more than 24 hours. It is particularly important to note that if the test result of 1 is negative, the health code will only turn green for a short time, and it will turn yellow again after 1, prompting the public to conduct the second test as required. If the results of both nucleic acid tests are negative, the health code will officially become a green code.
