Meng Jingbi 1, honorary president and scrapping professional committee of Chinese Acupuncture Association, told us how to distinguish the true from the false Xue, because there are dozens in the society and more than 20 provinces in China have done it, and everyone said that it originated from Sibin, Shandong, and China *. It is impossible to determine which product is native to Shandong; Therefore, Professor Zhiming from China and Bian Shi therapists suggested that Bian Shi Arena should be established in time under the supervision of relevant notary departments in order to standardize market behavior. 2. Bian Shi Datanchang: Please provide the certificate of origin, raw materials, products, coarse powder and 200-mesh fine powder, which will be stamped by the notary department and sent to the relevant state departments for testing at their own expense. 3. Stone product challenge: Look at the design, Mohs hardness, specific gravity, wetting degree, stone color, heating speed and heat preservation time, and the audible "rustling" sound when rubbing; 4. Geng Naiguang's New Bian Stone Therapy, first edition, page 28, Sibin Bian Stone is grayish yellow, and Liu, Xu and Wang Bian Stone Therapy and Health Beauty, page 42: Sibin pumice (raw material of Sibin Bian Stone) is produced in the coastal area of Surabaya, Shandong Province (Shandong enterprises declare China people), page 5. Discussion draft on the proposal of detecting Bian Shi in Bian Shi Challenge: detection contents (Bian Shi detection, Bian Shi detection, Bian Shi detection, Bian Shi detection, Bian Shi detection, Bian Shi detection, far infrared, negative ions (detectable by Institute of Remote Sensing, Chinese Academy of Sciences), ultrasonic wave and audible sound. (Dating) (Institute of Archaeology, Chinese Academy of Social Sciences) Thorium, uranium and other harmful radiation and chemical total element analysis (Beijing Geology and Mineral Analysis Center, Ministry of Nuclear Industry), and thorium, uranium and other harmful radiation can also be selected from the Institute of Engineering Health, Ministry of Health; Because there are more than 20 producing areas such as Shandong, Jiangsu, Anhui, Shanxi, Shaanxi, Jiangsu, Guizhou, Guangdong, Fujian and Henan. It is strange that everyone agrees that they are from Shandong. You have to look at the certificate of origin and test materials; 6. I am Meng Jingbi, honorary chairman of Bian Shi and Scraping Committee of Chinese Acupuncture Society, the former leader of Bian Shi (to be established) of Chinese Acupuncture Society. After communicating with other old experts, I have come to the following conclusions: 7. A famous professor of China Society and an expert of Bian Shi therapy declared that Bian Shi is a stone, whether it is true or not. 8. It is difficult for consumers to know how to tell. It is an international practice to ask for a certificate of origin, and then don't buy three-no products. 9. A well-known professor and expert of lithotomy therapy in China Society declared that manufacturers or products are no longer recommended, and only scientific research is conducted, not lithotomy identification, because there is no relevant testing equipment and technicians; If some staff in our hospital recommend manufacturers and products, it is not an organizational act, and our hospital will not bear the possible legal consequences. 10, the contents and achievements of the Bian Shi Challenge Hall are based on the "three principles" of fairness, justice and openness; Consumers choose to buy. Some pharmacies sell it, but it's hard to tell whether it's true or not.
