Qigong has two manifestations in limbs. One is static action. If you sit. Lying and standing, the other is moving, such as wuqinxi and baduanjin,
Qigong is a very complicated topic; There are different interpretations of religion and medicine, hehe. Being careless is like learning gossip. It's easier to get in than to get out. I have studied it myself for a while, and my advice to you is that there are videos in the basic theory of traditional Chinese medicine and Huangdi Neijing. Three books on acupuncture. Others were at sixes and sevens and took a wrong turn by accident.
