How to get the health code of the elderly? How can I get a health code without a smartphone?

If the elderly don't have a smart phone, they can ask their family or friends to download and register the health code, and then print out a screenshot of the QR code of the health code for the elderly to carry with them. In addition, you can also go to the community or hospitals and other institutions to ask the staff to help register the health code and provide the paper health code.
