What about Hefei yellow code on April 20, 2022?

Please strictly observe the hygiene at home, don't take buses and subways, don't enter any public places, and take samples and tests nearby on the premise of personal protection.

Three days after the two test results are negative, the negative certificate submitted online can turn into a green code.

During the epidemic, if your health code turns yellow, you need to report it to the community. Even if you don't report it, someone will contact you actively.
