The statement Left Liver and Right Lung is correct in the field of Chinese medicine, where the liver and lungs do not refer to the entities of the liver and lungs, but rather to the liver qi and lung qi. The full description of this statement is that the liver is born on the left and the lungs are hidden on the right. This is a theory unique to Chinese medicine. The liver is born on the left and the lungs are hidden on the right. Behind it are the ideas of Chinese medicine regarding the philosophy of yin and yang and the five elements. It specifically refers to the process of movement and change of the body’s qi. If a person is facing south, the left side represents east, which means the rise of qi, and the right side represents west, which means the fall of qi. The overall movement of qi is left ascending and right descending. This theory has some guiding significance both in judging the changes of disease mechanism and in choosing the corresponding treatment methods.
