（伯未按∶心恶热，肺恶寒，肝恶风，肾恶燥，脾恶湿。胃喜凉，肠喜热，胆喜温。亦不可不知。）
（足手）太阳（膀胱小肠）经，司（寒水火化）之气，手从足化，统称寒水，经行身之后。
（足手）阳明（胃大肠）经，司（燥土燥金）之气，足从手化，统称燥金，经行身之前。
（足手）少阳（胆三焦）经，司（木火相火）之气，足从手化，统称相火，经行身之侧。

（足手）厥阴（肝包络）经，司（风木相火）之气，手从足化，统称风木，分部于软胁。
（伯未按∶十二经之部位，手之三阴，从脏走手，手之三阳，从手走头。足之三阳，从头走足，足之三阴
，从足走腹。又有督脉，起于会阴，循背而
行身之后，所以督率诸阳。任脉起于会阴，循腹而行身之前，所以担任诸阴。冲脉亦起于会阴，夹脐而上散胸
中，当诸气之冲要。一源而三岐，统谓之奇经。）
小肠是心的腑，五行属火。主要功能是将食物转化为津液，向上输送以滋养心血。
胆是肝的腑，五行属木。主要功能是升发清气、降泄浊气，疏通和利导中焦脾胃的功能。
胃是脾的腑，五行属土。主要功能是接受和容纳水谷饮食，将其转化为气和血。
大肠是肺的腑，五行属金。主要功能是传送糟粕，消除和疏导停滞的气机。
膀胱是肾的腑，五行属水。主要功能是护卫体表的皮毛，通畅小便的排泄。
三焦是胞络和命门的腑，兼具水和火的属性。主要功能是运行水液、化生元气，贯通阴经与阳经。
（伯未按语：心厌恶热邪，肺厌恶寒邪，肝厌恶风邪，肾厌恶燥邪，脾厌恶湿邪。胃喜欢凉性环境，肠喜欢热性环境，胆喜欢温性环境。这些知识也是不可不知道的。）
足太阳膀胱经和手太阳小肠经，主管寒与水、火转化的气机，手经随足经变化，统称为寒水之气，经脉循行于身体背部。
足阳明胃经和手阳明大肠经，主管燥、土、燥、金的气机，足经随手经变化，统称为燥金之气，经脉循行于身体前部。
足少阳胆经和手少阳三焦经，主管木与相火的气机，足经随手经变化，统称为相火之气，经脉循行于身体侧面。
足太阴脾经和手太阴肺经，主管湿、土、清、金的气机，手经随足经变化，统称为湿土之气，分布于大腹部。
足少阴肾经和手少阴心经，主管水、阴、君火的气机，足经随手经变化，统称为君火之气，分布于小腹部。
足厥阴肝经和手厥阴心包络经，主管风与木、相火的气机，手经随足经变化，统称为风木之气，分布于软胁部。
（伯未按语：十二经脉的部位分布规律是：手部的三条阴经，从内脏走向手部；手部的三条阳经，从手部走向头部。足部的三条阳经，从头部走向足部；足部的三条阴经，从足部走向腹部。还有督脉，起始于会阴穴，沿背部循行于身体后方，所以能总督统领诸阳经。任脉起始于会阴穴，沿腹部循行于身体前方，所以能担任统领诸阴经。冲脉也起始于会阴穴，夹脐上行散入胸中，处于各种气机运行的关键要道。这三条脉同源而分三路，统称为奇经八脉中的奇经。）
The Small Intestine is the Fu organ of the Heart, belonging to Fire. Its primary function is to transform food into fluids and send them upward to nourish Heart blood.
The Gallbladder is the Fu organ of the Liver, belonging to Wood. Its primary function is to ascend clear Qi and descend turbid Qi, and to dredge and facilitate the middle Jiao (Spleen and Stomach).
The Stomach is the Fu organ of the Spleen, belonging to Earth. Its primary function is to receive and accept water and grain, transforming them into Qi and Blood.
The Large Intestine is the Fu organ of the Lung, belonging to Metal. Its primary function is to transport waste residues and eliminate stagnant Qi.
The Bladder is the Fu organ of the Kidney, belonging to Water. Its primary function is to guard the skin and hair, and to ensure the free flow of urination.
The Sanjiao (Triple Burner) is the Fu organ of the Bao Luo (Pericardium Collateral) and Mingmen (Gate of Life), possessing both Water and Fire attributes. Its primary function is to circulate water and transform Qi, connecting Yin and Yang meridians.
(Bowei's Note: The Heart dislikes Heat, the Lung dislikes Cold, the Liver dislikes Wind, the Kidney dislikes Dryness, and the Spleen dislikes Dampness. The Stomach prefers Coolness, the Intestines prefer Warmth, and the Gallbladder prefers Mildness. These points are also essential to know.)
The Foot-Taiyang (Bladder and Small Intestine) meridians govern the Qi of Cold, Water, and Fire transformation. The Hand meridian follows the Foot meridian's transformation, collectively termed "Cold Water," and these meridians run along the posterior aspect of the body.
The Foot-Yangming (Stomach and Large Intestine) meridians govern the Qi of Dryness, Earth, and Metal. The Foot meridian follows the Hand meridian's transformation, collectively termed "Dry Metal," and these meridians run along the anterior aspect of the body.
The Foot-Shaoyang (Gallbladder and Sanjiao) meridians govern the Qi of Wood and Ministerial Fire. The Foot meridian follows the Hand meridian's transformation, collectively termed "Ministerial Fire," and these meridians run along the lateral aspect of the body.
The Foot-Taiyin (Spleen and Lung) meridians govern the Qi of Dampness, Earth, and Clear Metal. The Hand meridian follows the Foot meridian's transformation, collectively termed "Damp Earth," and are distributed in the greater abdomen.
The Foot-Shaoyin (Kidney and Heart) meridians govern the Qi of Water, Yin, and Sovereign Fire. The Foot meridian follows the Hand meridian's transformation, collectively termed "Sovereign Fire," and are distributed in the lower abdomen.
The Foot-Jueyin (Liver and Pericardium) meridians govern the Qi of Wind, Wood, and Ministerial Fire. The Hand meridian follows the Foot meridian's transformation, collectively termed "Wind-Wood," and are distributed in the soft hypochondrium.
(Bowei's Note: Regarding the distribution of the Twelve Meridians: The Three Hand-Yin meridians travel from the Zang organs to the hands; the Three Hand-Yang meridians travel from the hands to the head. The Three Foot-Yang meridians travel from the head to the feet; the Three Foot-Yin meridians travel from the feet to the abdomen. Additionally, the Du Mai (Governor Vessel) originates at Huiyin (CV1), runs along the back on the posterior aspect of the body, thus governing all Yang meridians. The Ren Mai (Conception Vessel) originates at Huiyin (CV1), runs along the abdomen on the anterior aspect of the body, thus assuming responsibility for all Yin meridians. The Chong Mai (Penetrating Vessel) also originates at Huiyin (CV1), ascends flanking the umbilicus and disperses in the chest, occupying a critical position for the rush of all Qi. Originating from one source but branching into three, they are collectively referred to as the Extraordinary Vessels.)
