Liu Zi Jue, also known as "Six Healing Sounds Qigong," is a traditional Chinese qigong practice that involves a series of six breathing exercises, each associated with a different sound and organ of the body.

The six sounds are "Xu" (pronounced "shh"), "He" (pronounced "huh"), "Hu" (pronounced "who"), "Si" (pronounced "suh"), "Chui" (pronounced "chway"), and "Xi" (pronounced "she"). Each sound is associated with a different organ of the body, such as the lungs, kidneys, liver, heart, spleen, and triple warmer (a concept in Chinese medicine related to the body's metabolic processes).

The practice of Liu Zi Jue involves breathing in a specific way while making the sound associated with each organ. The movements are simple and gentle, and can be performed while standing, sitting, or lying down. The practice aims to promote the flow of qi (vital energy) through the body, improve organ function, and enhance overall health and well-being.

Liu Zi Jue is a popular qigong practice that has been used in China for centuries as a form of preventive and therapeutic healthcare. It is considered a gentle and accessible practice that can be practiced by people of all ages and fitness levels.
