Once you find yourself or your family's one-card health code abnormal, please immediately report your trip to the local village Committee or community for centralized or isolated health monitoring for 14 days. There is no abnormality after isolation, and then apply for decoding.
Health code is a personal two-dimensional code based on actual real data, which is declared by citizens or people who have returned to work online. Generated after background audit. As an individual entering and leaving the local electronic certificate, the QR code can be declared at one time, which is universal in the whole city.
