Hello, in fact, kung fu that can be used for actual combat and health preservation can be seen everywhere. However, actual combat requires hard work, and health care costs more money. This money is generally spent on health care. For example, people who used to practice iron sand palm spent a lot of money on medicine, a pot of medicine for promoting blood circulation and removing blood stasis, and used it to wash their hands after practice, so it wouldn't hurt their health. Otherwise, how can we say that the poor can't do martial arts, but they can't afford to keep in good health? Many people have practiced in actual combat, but they have no financial conditions to support them. This is why some people say that domestic boxing needs as much as the day after tomorrow, which is why many people give up kung fu and switch to modern fighting, because modern fighting is quick and scientific in training and diet. If it is not for professional purposes, this kind of exercise is good, of course, money is indispensable.
