Through the sorting and interpretation of the original text of Huangdi Neijing,it is known that there are two sets of channels.The 12 channels are originally derived from the 12 Zangfu organs of the innate body,and the main body nutrient qi circulation flows into the 12 Zangfu organs.The 11 meridians are originally derived from the number of the acquired yin and yang of the heaven and earth,'six in heaven and five in earth'.They are mainly derived from the intake of odor and transform it into nutrient qi,defensive qi,blood,qi and spirit in the lung and spleen,which are used to irrigate and nourish the body tissue.Since the spleen and stomach are centered and control the extremities and feet,the 11 meridians all originate from the hand,foot,wrist and ankle,and the five-shu points originate from below the elbow and knee.The spleen and stomach are the land,so the five elements of yin and yang,wood,fire,earth,gold and water are in the spleen.Channels are not only the channels for the passage and transmission of the acquired nutrient qi,defensive qi,and spirit,but also the channels for evil qi to invade the human body.Shaoyang triple energizer's ministerial fire generates spleen and stomach earth and controls the spleen and stomach yang qi.Therefore,the four limbs are the origin of all yang,and the 11 meridians start from the limbs and feet of the origin of all yang.Its essence is Shaoyang triple energizer,which is'the root of the twelve regular meridians'and'the twelve regular meridians are all derived from the origin of the vitality'.
