Liu Zy Jye, or Six Health Sounds, is a traditional health complex. It is based on the regulation of respiration. The Liu Jy Jie complex is based on the regulation and control of the rise and fall of Ki (vital energy) inside the body by performing exercises and uttering six sounds: SCH, HE, HU, SY, CHUI and SI. Exercise strengthens the liver, heart, spleen, kidneys, lungs and Sanjiao (three body cavities in which internal organs are located).
