Don't buy them. These are all health care projects that health care companies pay so-called experts to do. In these projects, the first few hundred callers will get free experience clothes. In fact, this is a lie. When you call in, your illness will get worse. Those who answer the phone are well-trained salesmen, and those who cheat are middle-aged and elderly people. The so-called ammonia sugar drugstore bought health care products, and the effect will be hehe.
