Health Cloud must have one ID number corresponding to one, and only one mobile phone number can be bound for real-name authentication. You can't use more than one ID card.
Bind the account number of the ID card, and then open the health code, which is your own, and then you can fill in some information and apply for your own health code.
Now the health code is not your own, it should be someone else's account you logged in, not your own ID card.
