Hard Qigong, to put it bluntly, is to tense the muscles to prevent injury, exercise certain parts (such as hands, elbows, knees, legs) of the pain tolerance, to be able to break a certain degree of hard objects and to withstand a certain power to hit the effect. The way to start hard qigong, first practice resistance, is to practice the ability to resist blows, because as the saying goes, "To hit people, first learn to take a beating." Move your body first, then take a steady horse stance, stretch your hands straight forward, and then think about transporting all the qi in your body to a certain body part. The innate qi is innate, without contact with qigong the average ordinary person can not be supplemented through the latter day, can only be to death has been in the consumption of innate yuan qi until there is no, and qigong practitioners cultivate to be able to enter into the level of the innate qi can be collected at will after the level of qigong practitioners can collect the level of innate qi is not a very high level of qigong, but only the beginner's level of qigong, so to say: the damage to this innate qi and the Therefore, there is no intrinsic connection between the damage to this innate qi and the effect of qigong cultivation to a higher realm!

Qigong is a very profound science, once you can seriously practice it, it will be of infinite use! Qi exists in the dantian of the martial arts practitioner and runs through the adjustment of breathing.
