1 Internal Skill

2 hard qigong

3 Fitness Qigong

1 internal strength has three functions: keeping healthy and living longer, hitting people is also the most powerful, and medicine is also very powerful.

Hard qigong, mainly hitting people, is definitely not as powerful as internal strength.

3 Fitness Qigong is health preservation, of course, there is no internal strength to maintain longevity.

What I learned is: internal strength.
