If not submitted, will the scan health code be yellow?

The scanned health code is not submitted, and the yellow code is not sent. Generally, the yellow code is due to network delay or someone using their own health code. You can modify your registration information, then log out of your account and log back in. Based on real data, the "health code" can be generated by citizens or people who have returned to work through their own online declaration. After background review, the QR code belongs to individuals. As an individual entering and leaving electronic certificate locally, the QR code can be declared at one time, which is universal in the whole city.
