What if the elderly don't have a smart phone health code?

If the elderly don't have smart phones, they can ask their families or caregivers to help them download and register health codes. If family members or caregivers can't operate, they can go to the local community health service center or government departments for consultation, and they will provide corresponding help and guidance. In addition, the elderly can also use paper health codes and need to apply to community health service centers or government departments.
