Yes, it is a liar. Don't believe it, dear. This is a scam. Not a regular company. At present, it is in a state of cancellation and bankruptcy. There is no information about this company at all. Do not believe! Moreover, negative ion health care is deceptive, and its effect on human body is not so great. Not only is negative ion health care deceptive, but all products about negative ions actually contain false ingredients, and their effects on human body are not so great. The concept of negative ion is actually a marketing tool, which will not have such a great impact on the human body, and the effect of health care is not so good. Negative ions are all false propaganda.
