According to the person in charge of Tianjin Yeung Yi Holographic Health Management Service Co., Ltd., compared with the traditional Bian Shi products, "Magnetic Bian Shi" is almost harsh in material selection and processing technology. All products are authentic dark brown "Sibin Pumice", and there are no stones of other colors. The appearance is more beautiful, and the feel is more delicate and smooth. By then, consumers who get new products will shine at the moment and feel the brand Bian Shi of Yeung Yi. "Magnetic Bianshi" is not only unique in appearance and technology, but also takes the lead in combining the dual functions of far infrared and magnetic therapy in Bianshi industry, and the health care effect is better when Bianshi is applied. At the same time, the relevant person in charge of Bian Shi, the brand of Yang Yi, also said: Now there are illegal vendors selling the so-called Bian Shi recommended by Teacher Yang Yi on the Internet, and even claiming that "one fake will pay 100 yuan, and one fake will pay 10,000 yuan", but according to their understanding, most of the low-priced Bian Shi sold by these illegal vendors is not pumice from Sibin, but made of marble, fishbone and even obsidian.
