It can help alleviate minor problems such as low back and leg pain, and naturally it is not as magical as the publicity effect. The health care industry chain generally works like this. Top people, proficient in customer psychology and advertising, know how to persuade people to be the most effective, write a new set of propaganda methods and marketing tactics, and then open a chain store. They know that their things are used to fool people. In order to avoid being vilified by others, they will not directly publicize it. The second level is the manager. The store manager believes in the authenticity of the marketing strategy in the promotional materials, and actually knows that the product effect and the product itself are unreliable (because he needs to purchase goods, knows the purchase price of goods, and naturally knows the weight of these things), but the store manager is not directly responsible for promoting products, so he will not expose that most products are actually from deception. The third level is the clerk who directly faces the customer. The shop assistants themselves are victims, who work the hardest and earn the least money. He really thinks that his products are effective and he can help customers by doing so. (Discovering that the product is a deceptive shop assistant, or can't stand the condemnation of conscience and change careers; Either you can lie without blinking, and the latter one ends up as a store manager or even opens a chain of his own. The customer is the one who is fooled. Because the clerk really thought what he said was true, everything seemed real. Of course, after a long time, if it doesn't work, customers won't buy it themselves. But there are many people in China, and everyone has a hole, which is also a lot of money. Besides, people always forget the pain in scars. Du Xiang, who was just cheated last year, came out. I saw the publicity this year and thought it was pretty good. Sometimes I know their strategy, but watching the store be fooled, I don't know. I'm here to fool others. I think people are so ignorant that it is good to be happy. Why expose yourself? Alas, in short, the first sentence when entering the beauty shop: I don't want a card, please don't fool me.
