Basically, the purpose of parkour is to quickly run over obstacles and make a leap. Later, I did some very ornamental pretending movements. It makes people feel good to watch. This is the same as lightness skill. In the past, I practiced Lightness Skill mostly to master an escape skill. It's just that some exercises are different from parkour. Parkour practice is on the same level as those who tie sandbags to their legs, jump into deep pits and climb over walls. Therefore, you can see that Chen Shixing, the Taoist priest of Wutangmen, who is known as the successor of light achievement, is not much different from those who practice parkour, and jumping again and again is within the tolerance of ordinary people. Because everything can be said to be a level thing. Some people say that lightness skill can be divided into ceiling lightness skill and site lightness skill, all of which belong to the category of site lightness skill. The so-called field flying skill simply means that you can't leave the ground and step on the clouds. I think we should call all those who can't fly parkour, and those who can jump out of the ordinary people's range light achievement. Because lightness skill is characterized by lightness. China's lightness skill system is relatively comprehensive, with drugs to soak bones and muscles and refine qi. Parkour is only the initial stage of lightness skill, and further study is needed. The key to practicing the legendary Lightness Skill lies in practicing Qi. Only by mastering the methods of practicing qigong can we hope to reach the realm of qigong. However, practicing Qigong is the healthiest and most comfortable.
