This requires us to provide them with a reasonable diet and take care of their daily lives. Don't let them easily believe in other people's bad intentions and be deceived by others. First of all, we must persuade them patiently. Tell them that it is not that we are reluctant to spend money on them, but that this medicine is really not suitable for them and really has no effect. If it works, we will be willing to spend money to buy it for them, which is also the most direct and effective. Moreover, this is an indirect method. We can tell them some short stories. For example, Lao Wang next door is obsessed with health care products, but his son and daughter-in-law disagree. So he sold the house secretly, and his son and daughter-in-law were very angry. Make a mess of the house. Lao Wang also lived in a welfare home and hasn't been home for a long time. Than go home. So this is a tragedy. I think an old man will feel something after listening to it! Perhaps indirectly, I can stop thinking about buying health care products, but at least I won't buy them myself. I won't do anything out of line. I think this, this approach should be more enlightening.
? Old people are sometimes like children. We can't yell at them. We should be patient and caring, so that they will listen and spend their old age happily.
