In addition, this light quantum therapeutic instrument actually uses light similar to infrared rays to promote local blood circulation and achieve certain anti-inflammatory effect. The cost is extremely low, and the price is more than ten times the cost. The main sales channel of this profiteering product is marketing. To put it bluntly, it is brainwashing, grasping the key points of low cognitive level, lack of affection, lack of care and spiritual emptiness of the elderly, launching a family offensive, giving pseudoscience lectures and controlling their thoughts. The salespeople who sold out the quantum therapeutic instrument are a group of extremely despicable social scum. In the face of money, their shameless degree is unimaginable. They will make your mother feel closer than her own children, so any advice you give your mother may be in vain, because you are no match for shameless people, and your mother will even put in a good word for liars.
I suggest you call the Food and Drug Administration and call the police directly. It may not work, but you have to scare them.
