Ok, you piqued my interest.
What is chi gung?
Edit, we can create another thread if it is awesome. Don’t want to threadjack.
chi gung translate as "energy exercise", the focus is on moving or feeling chi.
It could be a long serious of movements that would resemble a Tai Chi Chaun form, it could be a serious of short movements done sequentially, it could be just standing in a single or multiple postures.
Tai Chi focuses on chi also, there are some schools that only teach the form but a true tai chi school will also teach push hands, some form of a two person form and possibly a weapon such as sword or fan.
chi gung is mostly practiced for medical reasons; either for practitioners of traditional Chinese medicine to cultivate chi for working on people, or for ill or injured people to promote healing. A TCM practitioner might give some chi gung exercises to a person recovering from the virus to promote healing the lungs. the elderly might practice chi gung to promote longevity.
