First of all, we should understand that Qigong is a science, not a false superstition, and Qi exists objectively, otherwise it will not be Qigong but gymnastics. Another is to learn theory, learn from others and establish a correct concept of qigong. The most important thing is to succeed in study. No matter what qigong you teach, you must first have experience, otherwise you won't have the enthusiasm to teach qigong. No matter what you practice, I suggest you read Mr. Pang's book (Intelligent Qigong Essentials). When you concentrate on reading, your understanding of Qigong will be greatly sublimated.
