First, the elderly are usually children who go out to work, and they are alone in the countryside, so it is inconvenient to travel. So I usually have minor illnesses and pains, and generally don't go to big hospitals to see them. Either look at the small clinic near home or go to the drugstore to buy some medicine. And when an "expert" calls himself one day, he says that there is a kind of "Chinese medicine pill" that can treat pain without any side effects, and it can be sent home, and you can continue to buy it after eating. Under the guidance of "experts", the old man naturally agreed to send the medicine home without worrying about the children, so he took the bait. Second, many elderly people, especially those in rural areas, are illiterate and have no idea what is written on the drug packaging. Even if some old people can read, they don't know the difference between regular drug packaging and these fake drugs. So even if you get these drugs, you can't tell the difference between true and false. What determines whether they believe in this medicine depends entirely on the effect after taking it. If it can relieve the symptoms, it will be considered that the medicine is real, and this "expert" is very reliable, even passed on from mouth to mouth among the old people around. Old people who are ineffective because of wrong symptoms don't know how to refute complaints. Their voices can only sink into the sea.

Third, the reason why a liar can cheat success is because he only chooses people with small physical problems to buy. The anti-inflammatory and analgesic drugs are added to the fake drugs, and the pain sensitivity of the elderly decreases in a short period of time after taking them, causing the illusion that the condition is getting better, so they will think that this drug is really effective. After the medicine was used up, the disease recurred and I had to buy it again. Repeatedly, scammers can collect money continuously.

How can the elderly at home, especially in rural areas, avoid being cheated?

I think the most effective way is to tell your child what's wrong with your body in time. Let the children take time to take themselves to the hospital for examination or treatment, and listen to the doctor's advice on what medicine to take. If the children are not at home, what medicine did they buy? You can call your child to ask if these drugs are normal and suitable for your illness. Even if the child doesn't know how to use the medicine, at least he can check it online to see if the medicine is formal and symptomatic.
