手太阴肺经的原穴是太渊，作为主穴；手阳明大肠经的络穴是偏历，作为客穴。
手阳明大肠经的原穴是合谷，作为主穴；手太阴肺经的络穴是列缺，作为客穴。
足太阴脾经的原穴是太白，作为主穴；足阳明胃经的络穴是丰隆，作为客穴。
足阳明胃经的原穴是冲阳，作为主穴；足太阴脾经的络穴是公孙，作为客穴。

手太阳小肠经的原穴是腕骨，作为主穴；手少阴心经的络穴是通里，作为客穴。
足少阴肾经的原穴是太溪，作为主穴；足太阳膀胱经的络穴是飞扬，作为客穴。
足太阳膀胱经的原穴是京骨，作为主穴；足少阴肾经的络穴是大钟，作为客穴。
手少阳三焦经的原穴是阳池，作为主穴；手厥阴心包经的络穴是内关，作为客穴。
手厥阴心包经的原穴是太陵，作为主穴；手少阳三焦经的络穴是外关，作为客穴。

《难经》说：三焦之气运行于诸阳经。因此设置一个名称叫“原”。凡是治病，必须根据各经的主穴和客穴进行针刺。所谓“主”，就是原穴。所谓“客”，就是络穴。例如肺经发生病变，可以针刺本经的太渊原穴，再针刺大肠经的偏历络穴。其余经脉依此类推。
中府穴（肺之募穴） 巨阙穴（心之募穴） 期门穴（肝之募穴） 章门穴（脾之募穴） 京门穴（肾之募穴） 日月穴（胆之募穴） 中脘穴（胃之募穴） 天枢穴（大肠之募穴） 关元穴（小肠之募穴） 石门穴（三焦之募穴） 中极穴（膀胱之募穴）。
李东垣说：凡是治疗腹部的募穴，都是因为原气不足，这是从阴引阳的方法。如果是六淫（风、寒、暑、湿、燥、火）客邪侵袭，以及上热下寒、筋骨皮肉血脉的疾病，错误地取用胃经的合穴以及腹部各个募穴，必定会造成危险。
肺俞穴（位于第三椎骨下方） 心俞穴（位于第五椎骨下方） 肝俞穴（位于第九椎骨下方） 脾俞穴（位于第十一椎骨下方） 肾俞穴（位于第十四椎骨下方） 厥阴俞穴（位于第四椎骨下方） 胆俞穴（位于第十椎骨下方） 胃俞穴（位于第十二椎骨下方） 三焦俞穴（位于第十三椎骨下方） 大肠俞穴（位于第十六椎骨下方） 小肠俞穴（位于第十八椎骨下方） 膀胱俞穴（位于第十九椎骨下方）。
李东垣说：来自天外的风寒邪气乘虚侵入人体背部脏腑。人感受天外风邪，有两种说法。邪气中于阳分则流入经络。这种病始于外寒，最终归结为外热。所以治疗风寒邪气，要治疗各脏的背俞穴。（“募”通“膜”，指肌肉之间的膜系，是脏气结聚的地方，所以募穴在阴面。俞犹同输注的“输”，六阴六阳之气由此转输传送，所以俞穴在阳面。）

The *Nan Jing* (Classic of Difficult Issues) states: The Qi of the Sanjiao (Triple Burner) circulates through all Yang meridians. Therefore, a specific designation called "Yuan" (Original) was established. In treating any disease, one must needle according to the Master and Guest points of each respective meridian. The "Master" refers to the Yuan-Source point. The "Guest" refers to the Luo-Connecting point. For example, if there is pathology in the Lung Meridian, one may needle the Yuan-Source point Taiyuan (LU9) of this meridian, and additionally needle the Luo-Connecting point Pianli (LI6) of the Large Intestine Meridian. The remaining meridians follow this pattern.
Zhongfu (LU1, Front-Mu point of the Lung) Jueque (CV14, Front-Mu point of the Heart) Qimen (LR14, Front-Mu point of the Liver) Zhangmen (LR13, Front-Mu point of the Spleen) Jingmen (GB25, Front-Mu point of the Kidney) Riyue (GB24, Front-Mu point of the Gallbladder) Zhongwan (CV12, Front-Mu point of the Stomach) Tianshu (ST25, Front-Mu point of the Large Intestine) Guanyuan (CV4, Front-Mu point of the Small Intestine) Shimen (CV5, Front-Mu point of the Sanjiao/Triple Burner) Zhongji (CV3, Front-Mu point of the Bladder).
Li Dongyuan stated: Whenever treating the Front-Mu points on the abdomen, it is due to a deficiency of Original Qi (Yuan Qi), which constitutes drawing from Yin to guide Yang. If the condition involves pathogenic factors from the Six Excesses (Liu Yin: Wind, Cold, Summerheat, Dampness, Dryness, Fire) or conditions such as upper heat and lower cold, or diseases affecting sinews, bones, skin, flesh, vessels, and blood, erroneously selecting the He-Sea point of the Stomach Meridian or various abdominal Front-Mu points will inevitably lead to danger.

Li Dongyuan stated: Wind-cold pathogens from heaven invade the interior and enter the back organs. Regarding human susceptibility to external wind pathogens, there are two theories. If pathogens strike the Yang aspect, they flow into the meridians. Such diseases begin with external cold and ultimately manifest as external heat. Therefore, when treating wind-cold pathogens, one should treat the Back-Shu points of the respective organs. ("Mu" is interchangeable with "Mo," referring to the membranes between muscles, which are sites where Zang organ Qi gathers; thus, Mu points are on the Yin side. "Shu" is analogous to the transport function; the Qi of the six Yin and six Yang meridians is transported and transmitted through these points; thus, Shu points are on the Yang side.)
