The little white bottle on the knee is fake. Because the little white bottle on his knee came from the program of "Health Exchange of Yaowang", Liu Hongbin painted it on his knee with a little white bottle containing Yaowang Fengtong recipe, and the old patient with rheumatic bone pain who had been ill for decades recovered on the spot, which is a medical miracle. However, Liu Hongbin was soon found wearing nine vests to promote different health products. These health care products, which were hyped up by Liu Jiaoshou, not only had no real efficacy, but some were even found to contain toxic substances such as Sudan red. Liu Hongbin himself is not an expert professor. When the news came out, people's hospitals in Peking University, beijing ditan hospital and Jilin Province, etc. Announced in succession that there was no such person. So the little white knee bottle is fake.
