What can I take instead of a health certificate without an ID card?

If you don't bring your ID card when you apply for a health certificate, the party concerned can show the medical staff an electronic identity to prove their identity, that is, open the Alipay homepage, click the card package at the top, click the certificate at the top inside the card package, click View Electronic Certificate below the ID card in the certificate, and finally hand over the electronic identity in Alipay to the relevant personnel.
