When people reach a certain age, there will always be some organ problems, which will inevitably bring inconvenience and pain to the elderly, so they are always worried that small problems will develop into big problems and affect their life span. Those swindlers captured the psychology of the old people. On the one hand, they talk about minor illnesses that may lead to serious diseases and even cancer. On the other hand, they exaggerate the efficacy of a drug, and even regard health care products as a panacea for all diseases. No matter whether the old people ask them if this medicine can cure a disease, they will give a positive answer, so as to attract business and cheat money. However, most elderly people know little about medical knowledge and lack awareness of prevention. Therefore, some scammers think that as long as they don't "eat dead" drugs, there will be no problem, and they can boldly brag and deceive people. Many elderly people spend a lot of money to buy a bunch of medicines, some of which are ordinary health care products, which can't cure the disease at all. To make matters worse, some of them are fake medicines.
