Why did I stay at home for 15 days, and Beijing Health Code didn't?

You should be asking "Why didn't I have a health code in Beijing 15 days"? Because people who punch in for fifteen days will not have a health code until after twelve o'clock on the fifteenth night.

The reason why the QR code of Beijing Health Code is not displayed:

1. It may be a network problem. Try changing the network.

Maybe there is something wrong with the system. Try to wait for the system to repair.
