This is a exercise, I’m not sure I want to call it qigong, and some branches call it Yang Taiji’s version of “Baduajin”, however I find it is more like Dao Yin.
Both teachers who have taught this to me were both from Taiwan. One did it as a warm-up before Taiji. The other used it at the end of class after Hsing-yi practice.
It was written in both Chen Yanlin’s book. Also the book “Tao of Tai Chi Chuan” by Jou Tung Hwa wrote about calling it a Qigong.
This website discusses it, translation of Chen Yanlin’s book:
Video samples of the exercises:
“This is a Tai Chi Qigong that I learned from Jou, Tsung Hwa and Shih, Tzu Guo. It was apparently first published in a book by Yearning K. Chen around 1930 and had been part of the Yang family secret teachings for many years. Currently available books by Jou, Tsung Hwa (Tai Chi Chuan: the Tao of Rejuvination) and by Stuart Olson (Cultivating the Ch’i) discuss this exercise in detail. This video is humbly offered to suppliment class work and provide a reference for students to review at home.
Inhale through the nose, exhale from the mouth. This set can be done with Natural Breathing or Reverse Breathing (when properly learned). When done with Reverse Breathing the sounds “Heng” and “Haa” can be added to inhaling and exhaling respectively.”
Another person from Taiwan writes:
“I also learned it in a Yang style school in Taiwan, called neigong, with some clear differences to the the last vid. Stuart Olson’s translation I don’t like much, personal thing.
We stand on shoulder wide apart feet and breath from the dantian to the mingmen and back, with contraction while inhaling and big belly while exhaling (reverse breathing).
I like it very much, does engergize in a relaxed way, one of my 3 part warm-up for Yang style training days:
stretching, breathing, stepping (+ standing).”
Those expert advice, give us some clues to work with.
Two other video variations forund on Youtube:
The first two videos closely resemble the version I have learned. This is one of my favorites:
