The Chi Kung form demonstrated on this DVD was taught to me by Zhang Guang De, professor of the Chi Kung department at Bejing University. Master Zhang cured himself of lung cancer, using this very form. Those of you who saw the Public Television show with Bill Moyers entitled "Healing and the Mind" may remember the long segment in the very first episode of the series devoted to the practice of Chi Kung. Practice these exercises and you will realize why Chi Kung is so highly regarded in China.
