The five elements are combined with the five zang-organs and six fu-organs. The jingle is that the liver gives birth to the heart, the heart gives birth to the spleen, the spleen gives birth to the lung, the lung gives birth to the kidney, and the kidney gives birth to the liver. Liver governs spleen, spleen governs kidney, kidney governs heart, heart governs lung, and lung governs liver.

The liver gives birth to the heart, that is, wood makes a fire, such as the liver storing blood to help the heart; If the heart gives birth to spleen, fire gives birth to earth. For example, the yang of the heart can ask the spleen. Spleen gives birth to lung as soil gives birth to gold, such as spleen transporting the essence of Shui Gu, which can benefit lung; Lung and kidney are golden raw water. When the lung qi is clear, the body fluid will drop and nourish the kidney. Kidney generates liver as aquatic wood, such as kidney storing essence and nourishing liver yin and blood.

The theory of five elements has some limitations in explaining the balanced relationship between zang-fu organs. This is because the five zang-organs correspond to the five elements only to extract some characteristics of the five zang-organs, and the five elements can not explain all the phenomena in the world, but only part of the relationship.
