Fake! A small bottle of liquid, mixed with water, is harmless to the body, but it is useless. The headband in wechat is quite like that! In fact, it is a perfect liar organization. They also have a Shenzhen woman who claims to work in Taichung, Taiwan Province. After buying it, she started fooling around and finally ignored you. And this woman basks in the feedback from customers every day, losing 4 kg and 5 kg a day, and basking in her luxurious life. They all call themselves teachers. I think they are all fucking liars. They are a complete chain of deception! Don't be fooled by their customer feedback! It's terrible. I hope the police can participate in the investigation. End this trap mechanism!
