What if the health code doesn't come out?

The health code can't be loaded, which may be caused by network reasons at first. Users are advised to check the networking status of the mobile phone, disconnect and reconnect the mobile phone network, or directly turn off and restart the mobile phone, which can generally solve the problem.

If the problem cannot be solved, it may be caused by a procedural problem. Users are advised to quit the program and try again, or try again after a while.
