Zhen Qi is known as "True Qi" since it is the final stage in the Theory of Qi Transformations.

Zong Qi or Gathering Qi becomes Zhen Qi thanks to Original Qi

Literally this is the Qi that circulates through the body via the channels and nourishes the internal organs and is the result of a whole process of refinement and transformation of energy.

This process takes place in the Lungs: That is why they are known as being in charge of controlling Qi.

• Food-Qi arrives
• Food-Qi combines with inhaled Oxygen creating Zong Qi.
• Zong Qi is catalyzed by Original Qi forming Zhen Qi.

Zhen Qi takes on two distinct "forms":

• Rong Qi or Nutritive Qi.
• Wei Qi or Defensive Qi.
