First of all, I think there are only two classic health preserving techniques in China, which have a long history and can be described by concepts or names: Wuqinxi and Liuzijue. Comparatively speaking, the six-character formula is authentic and operable, but in terms of influence, it is far less than the later ones such as the Book of Changes and Washing the Marrow. Therefore, the older you get, the stronger you get, and the latecomers come from the top, which is the same from ancient times to the present. Pilates is produced from a broader perspective. For example, in some encyclopedias, we can see that it seems to be a comprehensive product of ancient Greek strength training, yoga and Tai Chi, so it seems more scientific, effective and even better. If the subject could look at this problem from a broader perspective, there would be no feeling that people today are rich and thin. Secondly, we must pay attention to this problem: women are almost the only key force to guide the development of this society and even the world. Women choose and eliminate men through mate selection criteria. Furthermore, the survival of the fittest or an aesthetic result is achieved by feeding offspring, which leads to the effective self-adjustment of men in this society on the basis of reproduction in order to adapt to social aesthetics. When a fitness technology meets the needs of this instinct and instinct, its development is a trend that is almost crushed. Finally, because I don't know much about the problem solver, I want to discuss with him the commercialization of the six-character formula in traditional fitness. Brother Rou Wang Maru, the six-character formula is most like Pilates, or the operation mode is breathing, that is, Pilates inhales and exhales through his nose, while the six-character formula is exhaling and vocalizing. The six-character formula has a limit on the number of times, and one word is six times. Can you arrange different traditional and modern fitness exercises here? Can his breathing frequency and adjustment be effectively related to the so-called sense of qi, an ancient health-keeping term, and can it be defined as a new type in modern fitness? Wait, these are actually the technical core requirements on the basis of commercialization. This is the business opportunity.
