How to persuade my father not to buy those advertised "magic drugs" and not to spend a lot of money on them?

As soon as you listened, I knew you were a child. First of all, you have your own problems, at least lack of communication. First of all, you should tell your father that it's not that you won't treat him, as long as it is symptomatic and effective, you firmly support it. Second, you can tell your father that as long as it promotes sales, 90% are fake. Fake drugs generally have no drug batch number, which is a "national medicine quasi-word". Moreover, health care products are used as medicines, but health care products cannot be used for treatment, and there are some fake batch numbers from other manufacturers. What's more, at first, a group of people came to sell it, and they gave you a course of medicine for free, which was really useful and gave you a physical examination for free. The examination results also show that your condition has improved, and everyone has paid for it. At this time, the medicine is not necessarily true. There are many such scams. Of course, it is not excluded that some regular manufacturers do community marketing. After all, don't buy or sell under uncertain circumstances. Then tell him the harm of counterfeit drugs: counterfeit drugs can not only cure diseases, but also delay the illness, and may miss the opportunity of treatment and aggravate the illness. In addition, drugs should not be eaten indiscriminately, which is a three-point poison. Long-term drug use will increase drug resistance, dependence and toxin deposition in the body. Take it as directed by the doctor. You don't have to listen to anyone, but you must listen to the doctor if you want to cure the disease! If the patient can cure the disease by buying medicine himself, what's the use of the hospital, and the pharmaceutical factory can fix it.
