How to change from yellow code to green code when passing through Linyi

Although you passed a high-risk area and the health code turned yellow, the nucleic acid test was negative, indicating that you were not infected. COVID-19, the health code naturally turns green.

Health code plays an important role in epidemic prevention and control and production recovery, which is conducive to efficient personnel management. Maintaining green code can avoid unnecessary troubles.
