I believe that this Qi Gong was developed by Master Tung Kai Ying in honor of his father who was confined to a wheel chair in his last days. Tung Kai Ying thought that everyone could benefit from this form and has taught it to his students since.  I also heard that Master Tung Hu Ling developed it while in his wheel chair and that his son (TKY) then taught it to his students in honor of his father. 

     When Tung Kai Ying originally introduced it to his students, we were instructed to do each of the nine movements nine times. Later he had his students do movements four times each then in reverse order do each movement four times again. 

A poem by Emilio Gonzales a long time San Francisco Taiji teacher and senior student of Master Tung Kai Ying, is helpful to remember the the sequence to this Qi Gong :

                  Taiji Qi Gong

The Heaven opened and out of the skies
The Fair Lady wove Heaven and Earth.
The Tiger forced the Wild Horse to the knees.
The two strong Winds Crossed the river,
and Pushed the boat back to the shore.
