（《灵枢·周痹篇》 全）
黄帝问于岐伯曰∶周痹之在身也，上下移徙随脉，其上下左右相应，间不容空，愿闻此痛，在血脉之中邪？将在分
肉之间乎？何以致是？其痛之移也，间不及下针，其 痛之时，不及定治，而痛已止矣，何道使然？愿闻其故。（邪，耶
同。肉有分理，故曰分肉。 痛，动而痛也。间不及下针，即不及定治之谓，言移易之速也。 音触。）岐伯答曰∶此众
痹也，非周痹也。黄帝曰∶愿闻众痹。岐伯对曰∶此各在其处，更发更止，更居更起，以右应左，以左应右，非能周也，
更发更休也。（各在其处，谓随聚而发也。不能周遍上下，但或左或右，更发更休，患无定所，故曰众痹。）黄帝曰∶善。
刺之奈何？岐伯对曰∶刺此者，痛虽亦止，必刺其处，勿令复起。（必刺其处，谓刺其原痛之处也。治从其本，故可勿令
复起。）
帝曰∶善。愿闻周痹何如？岐伯对曰∶周痹者，在于血脉之中，随脉以上，随脉以下，不能左右，各当其所。（能上
能下，但随血脉而周遍于身，故曰周痹，非若众痹之左右移易也。）黄帝曰∶刺之奈何？岐伯对曰∶痛从上下者，先刺其
下以过之，后刺其上以脱之；痛从下上者，先刺其上以过之，后刺其下以脱之。（过者，去之之谓。脱者，拔绝之谓。先
刺以过之，去其标也。后刺以脱之，拔其本也。）黄帝曰∶善。此痛安生？何因而有名？岐伯对曰∶风寒湿气客于外，分
肉之间，迫切而为沫，沫得寒则聚，聚则排分肉而分裂也，分裂则痛；（邪气客于肌表，渐入分肉之间，则迫切津液而为
汁沫，沫得寒则聚而不散，故排裂肉理为痛。）痛则神归之，神归之则热，热则痛解，痛解则厥，厥则他痹发，发则如是。
（痛则心注其处，故神归之。神归即气归也，气归则热，热则寒散而痛暂解；然其逆气仍在，故痛虽解而厥未除，则别
有所聚，故或自上而下，或自下而上，他痹发矣，是名周痹，发仍如此。）此内不在脏，而外未发于皮，独居分肉之间，
真气不能周，故命曰周痹。（真气不能周，即气闭不行也，故曰痹者闭也。此节上旧有帝曰善余已得其意矣九字，乃下文
之误复于此者，今删去之。）故刺痹者，必先切循其下之六经，视其虚实，及大络之血结而不通，及虚而脉陷空者而调之，
熨而通之，其螈坚转，引而行之。（下之六经，足六经也。大络之血结者，宜泻之；虚而脉陷空者，宜补之；寒凝而气不
周者，宜熨而通之；其螈坚转者，螈急转筋之谓，当针引其气而行之也。螈音炽。）黄帝曰∶善。余已得其意矣，亦得其
事也。九者，经巽之理，十二经脉阴阳之病也。（意者，病之情也。事者，治之法也。九者，针也。巽者，具也。言其意
其法，在乎九针，而经具其理，凡十二经脉阴阳之病，无不尽于是也。）
《灵枢·周痹篇》（全文）
黄帝向岐伯问道：周痹存在于身体中，疼痛位置上下移动并跟随经脉走向，左右上下相互呼应，中间没有空隙。我想知道这种疼痛是在血脉之中呢？还是在分肉之间？它是如何导致这种情况的？当疼痛转移时，快得来不及下针；当疼痛发作时，快得来不及确定治疗方案，而疼痛就已经停止了。这是什么道理导致的？我希望了解其中的原因。（“邪”同“耶”。肌肉有纹理，所以称为分肉。“痛”指因触动而产生的疼痛。“间不及下针”，即来不及确定治疗方案，意思是疼痛转移速度极快。“音触”。）
岐伯回答说：众痹各自停留在固定的部位，交替发作又停止，交替停留又起身，右侧对应左侧，左侧对应右侧，不能遍及全身，是交替发作、交替休止的。（各自停留在固定部位，是指随着邪气聚集而发作。不能遍及上下，只是或左或右，交替发作又休止，患病部位不定，所以称为众痹。）
岐伯回答说：针刺这种病，虽然疼痛也会停止，但必须针刺其原发部位，不要让它再次复发。（必须针刺其原发部位，即针刺最初疼痛的地方。治疗从根本入手，所以可以防止复发。）
岐伯回答说：周痹位于血脉之中，随经脉向上行，随经脉向下行，不能向左右移动，各自处于其所对应的部位。（能上能下，但随血脉在周身循环，所以称为周痹，不像众痹那样左右移动变化。）
岐伯回答说：疼痛从上往下走的，先针刺下部以截断病势，后针刺上部以去除病根；疼痛从下往上走的，先针刺上部以截断病势，后针刺下部以去除病根。（“过”的意思是去除它。 “脱”的意思是拔除绝断它。先针刺是为了去除标症，后针刺是为了拔除本根。）
岐伯回答说：风寒湿邪气客居在体表，进入分肉之间，逼迫津液凝结成沫，沫遇到寒气则聚集，聚集后就会排挤分肉使其分裂，分裂就会产生疼痛；（邪气客居在肌表，逐渐进入分肉之间，就会逼迫津液变成汁沫，沫遇到寒气则聚集不散，所以排裂肌肉纹理产生疼痛。）疼痛时精神注意力集中在患处，精神集中则产生热感，热感使疼痛暂时缓解，疼痛缓解后出现气机逆乱，气机逆乱则其他部位的痹证发作，发作时就是这样。（疼痛时心神专注于该处，所以精神归于此。精神归集即气也归集，气归集则生热，热则寒散而疼痛暂时解除；然而逆气仍在，所以虽然疼痛解除但气机未通，则气会在别处聚集，所以或从上到下，或从下到上，其他痹证发作了，这叫做周痹，发作情况依然如此。）这种病内不在脏腑，外未发散于皮肤，独自居于分肉之间，真气不能周流全身，所以命名为周痹。（真气不能周流，就是气机闭塞不通的意思，所以说痹就是闭的意思。这一节上面原有“帝曰善余已得其意矣”九个字，是下文内容的误复在此处，现已删去。）所以针刺痹证，必须先切按循摸下肢的六条经脉，观察其虚实情况，以及大络脉中血液结滞不通的情况，还有虚损导致脉象凹陷空虚的情况并进行调理，用熨法来疏通它们，对于肌肉抽搐、筋脉拘急扭转的情况，通过引导经气来运行它。（下肢的六条经脉，指足部的六条经脉。大络脉中血液结滞的，应当泻法；虚损而脉象凹陷空虚的，应当补法；寒凝导致气机不周的，应当用熨法来疏通；对于肌肉抽搐、筋脉拘急扭转的，“螈”指筋脉紧急扭转，应当用针引导经气使其运行。“螈”读音为chì。）
黄帝说：好。我已经领会了其中的意旨，也掌握了治疗方法。九种针具，具备经络的道理，是十二经脉阴阳病变的治疗依据。（意旨，是指病情的实质。方法，是指治疗的法则。九者，指针具。巽者，具备的意思。意思是说，病情和治疗法则都蕴含在九针之中，而经络具备了相应的原理，凡是十二经脉阴阳的各种疾病，无不包含在其中。）
*Ling Shu: Zhou Bi Chapter* (Full Text)
The Yellow Emperor asked Qibo, "Zhou Bi (General Bi Syndrome) exists in the body; its pain migrates up and down following the meridians, with corresponding reactions on the upper/lower and left/right sides, leaving no gaps. I wish to know: is this pain located within the blood vessels (Xue Mai), or between the muscle layers (Fen Rou)? How does it arise? When the pain shifts, it moves too quickly to insert a needle; when it flares, it changes too rapidly to determine treatment, yet the pain ceases before treatment can be applied. What principle causes this? I wish to understand the reason." ('Xie' is synonymous with 'Ye'. Muscles have grain-like textures, hence called Fen Rou. 'Tong' refers to pain caused by movement/agitation. 'Jian bu ji xia zhen' means there is insufficient time to determine treatment, indicating the speed of migration. Pronunciation: chu.)
Qibo replied, "This is Zhong Bi (Multiple/Clustered Bi Syndrome), not Zhou Bi."
The Yellow Emperor said, "I wish to hear about Zhong Bi."
Qibo answered, "Zhong Bi resides in specific locations, alternating between flare-ups and cessation, staying and rising again. The right corresponds to the left, and the left to the right. It cannot circulate throughout the entire body but alternates in occurrence and rest." (Residing in specific locations means it flares where pathogens gather. It cannot circulate fully up and down, only appearing on the left or right, alternating in flare-up and rest, with unpredictable sites, thus called Zhong Bi.)
The Yellow Emperor said, "Excellent. How should it needled?"
Qibo replied, "When needling this condition, although the pain may cease, one must definitely needle the original site to prevent recurrence." (Needling the original site means targeting the initial location of pain. Treating from the root prevents recurrence.)
The Yellow Emperor said, "Excellent. I wish to know what Zhou Bi is like."
Qibo replied, "Zhou Bi lies within the blood vessels, moving upward along the meridians and downward along the meridians, without lateral movement, each occurring at its respective position." (Capable of moving up and down, circulating through the body via the blood vessels, hence called Zhou Bi, unlike Zhong Bi which shifts laterally.)
The Yellow Emperor said, "How should it be needled?"
Qibo replied, "If the pain moves from top to bottom, first needle the lower part to intercept the pathogenic factor, then needle the upper part to eliminate the root cause. If the pain moves from bottom to top, first needle the upper part to intercept the pathogenic factor, then needle the lower part to eliminate the root cause." ('Guo' means to remove/pass through. 'Tuo' means to extract/cut off completely. Needling first removes the branch/symptom; needling second extracts the root/cause.)
The Yellow Emperor said, "Excellent. How is this pain generated? Why is it named so?"
Qibo replied, "Wind-Cold-Dampness pathogens lodge externally, between the muscle layers, pressing the fluids into foam. When the foam encounters cold, it aggregates; aggregation pushes against the muscle layers causing separation, and separation results in pain." (Pathogens lodging in the muscle surface gradually enter the Fen Rou, pressing body fluids into juice-foam. This foam aggregates due to cold and does not dissipate, thus splitting the muscle texture and causing pain.) When pain occurs, the spirit (Shen) focuses on the affected area; focus generates heat; heat resolves the pain temporarily; after resolution, Qi rebellion (Jue) occurs; Qi rebellion triggers other Bi syndromes elsewhere, manifesting as described above. (When in pain, the mind concentrates on the site, so Shen returns there. Shen returning implies Qi returning; Qi returning generates heat, dispersing cold and temporarily relieving pain. However, rebellious Qi remains, so even if pain resolves, Qi obstruction persists, leading to accumulation elsewhere. Thus, Bi syndromes may occur from top-to-bottom or bottom-to-top, termed Zhou Bi, with such manifestations.) This pathology is internally not in the Zang-Fu organs, nor externally manifested in the skin, but resides solely between the muscle layers. Since the True Qi (Zhen Qi) cannot circulate freely, it is named Zhou Bi. (True Qi failing to circulate indicates Qi blockage; hence Bi means closure. The phrase 'The Emperor said: Excellent, I have grasped its meaning' previously found here is a duplication error from the following text and has been deleted.) Therefore, when needling Bi syndromes, one must first palpate the six meridians of the lower limbs, assess their deficiency or excess, examine large collaterals for blood stasis and obstruction, and identify areas of deficiency where pulses are sunken and empty, then regulate them. Use moxibustion/warming therapy to unblock them. For muscle twitching and tendon contraction/torsion, guide the Qi to promote circulation." (The six meridians below refer to the Foot meridians. Blood stasis in large collaterals requires draining; deficiency with sunken pulses requires tonifying; Cold stagnation with Qi obstruction requires warming/unblocking therapy. 'Chong' refers to acute tendon contraction/torsion, requiring needle guidance to move Qi. Pronunciation: chi.)
The Yellow Emperor said, "Excellent. I have grasped the intent and mastered the methods. The nine needles embody the principles of the meridians and are the basis for treating diseases of Yin and Yang in the twelve primary meridians." (Intent refers to the nature of the disease. Method refers to the therapeutic approach. 'Nine' refers to the nine needles. 'Xun' means complete/equipped. This means that both the understanding of the disease and the therapeutic methods reside in the nine needles, which encompass the principles of the meridians, covering all diseases of Yin and Yang in the twelve primary meridians.)
