For more than one thousand years, Muscle/Tendon Changing and Marrow/Brain Washing Chi Kung have been considered the most effective way to gain health and longevity.

In addition, they have also been used by Chinese Buddhist and Taoist monks as aids in achieving the goal of Buddhahood or enlightenment.

These two exercises are used for Water and Fire (Kan and Lii) training, which produces the harmonious interaction of the body`s Yin and Yang. The theory of the mutual balance of Yin and Yang is at the root of Chinese CHi Kung, and it is valid today as it was when it was created.
