I don't feel as good as Xilaijian. Although it is rolled from head to toe, it does not conform to the human structure. Don't be embarrassed. It has many kinds of patterns, and it also uses medicine and moxibustion, but people like the machine Xilaijian, and the effect is better than it. Some people have to compare this for a long time. For example, do Xilaijian for three months, and then do Kang Yijian for three months, and try which one is better.
