From a realistic point of view, the elderly want to understand the smartphone is too difficult, want to solve this problem, we should take into account the group is still very large, practical development of some policies, is the most appropriate. For example, real-name registration, or community or hospital issued health certificates and so on, these practical considerations of the actual situation of the elderly ways and means, is really a humane method, is the method of respect for the elderly, is really the old man this group in the heart of the method.
During the epidemic, when the home quarantine, this contradiction of the elderly not being able to provide a health code is not very prominent. But after the end of the epidemic, when the elderly can go out with the usual fitness, square dancing, sometimes you need to take the car, sometimes you need to go to the park. In such cases, the elderly will be hindered by the fact that they cannot provide a health code. Obviously some old people are old and really don't know or understand some new things. In this case, the old people are actually very anxious and confused when they are asked for a health code. The old man is the old man, both physically and mentally already and young people can not be compared, in the communication and exchange with the elderly, posture should be lower, the language should be more gentle, the attitude should be better. If the elderly still don't understand what they are being taught, they might as well register their real names! If there is a problem, through the real name is also traceable.
