Dr Paul Lam explain what is Qi. It is the life energy inside a person. Qi comes from the combination of three things: the air breathed in through the lungs, essential Qi from the kidney, and the Qi absorbed from food and water through the digestive system. Qi circulates throughout the body, performing many functions to maintain good health. The stronger Qi you have, the healthier and stronger you are. The ultimate purpose of tai chi is to cultivate stronger and healthier Qi.
