For example (it may be a bit inappropriate, but the truth should be like this), before practicing advanced martial arts, you will learn basic kung fu, such as "horse stance just look" and "standing pile". This is a basic course before practicing martial arts, just like the "model" in calligraphy, and the teachers who teach these may have various sects, just like "Yan, Liu and Ou". Regardless of the teaching of any sect, the basic stance and stance form are the same, which means that you can practice these basic martial arts in the Tiger Sect, then practice crane boxing in the Crane Sect, or learn the basics in the Monkey Sect, and then practice tiger boxing in the Tiger Sect (hehe, of course, these boxers have to be open-minded). The quality of basic practice depends on how much effort and mystery the practitioners have made.
In addition, if you want to practice calligraphy or form a genre, it is inevitable to learn more about the strengths of each genre ... If you just want to practice a certain body, then what kind of basic exercises are based on personal likes and dislikes, and there is no substantive difference.
