（足面也）〔中间〕属足阳明胃经（《灵枢》曰∶足阳明之脉，循胫外廉，下足跗，入
中趾内间。又曰∶两跗之上，脉坚陷者，足阳明病，此胃脉也。《素问》曰∶身重难以行者，胃脉在足故也。
张三锡曰∶冲阳穴，在足跗上五寸陷中，暴厥脉伏者，有此可救，所谓有胃气者是也）。又属足太阴脾经（《素
问》曰∶下部人，足太阴也，以候脾胃之气。注∶胃脉在足跗上冲阳之分，动应于手，以候胃，兼候脾。又曰∶
饮食不下，舌本强；食则呕，冷泄，腹胀；溏泄痢，水闭，病本于脾。冲阳绝，死不治也）。〔内廉〕属足
厥阴肝经（《灵枢》曰∶足厥阴之脉，起于大趾丛毛之际，上循足跗上廉。又曰∶阴中之少阳，肝也，其原出
于太冲。太冲，足大趾上二寸陷者之中也，为输。《素问》曰∶丈夫 疝，妇人少腹痛，目眯 ，疡疮痤痈，
病本于肝。太冲绝，死不治。沈承之曰∶跗上有太冲穴，一名冲阳，又名跗阳，在两跗上大趾次趾本节后二
寸许，寻摸动脉陷中。穴中有脉则生，无脉则死。益由此穴乃足厥阴脉之所注，肝之输也，足阳明脉之所过，
胃之原也。肝为生发之源，胃为五脏之本，以其能冲贯百骸，营养诸经，故谓之冲也。二经相须，未有肝死而
胃独生，胃绝而肝犹在者。故异经而同穴，不必分其孰为肝、孰为胃也。然须诊太溪穴，以参决之。顾英白曰∶
太冲为足厥阴之输穴，冲阳为足阳明之原穴，二穴虽相近，而实则各异。至于胆经之跗阳，又在外踝之上，承
之乃合而为一，此愚之不能解者也。冲阳本属胃，而兼以候脾之绝者，脾与胃相表里，后人何得师心而自用
耶）。〔外廉〕属足少阳胆经（《灵枢》曰∶足少阳之脉，循足跗上，入小趾次趾之间；其支者，别跗上，
入大趾之间。又曰∶足
少阳之别，名曰光明，去踝上五寸，别走厥阴，下络足跗。实则厥，虚则痿 ，坐不能起，取之所别也）。
又属冲脉（《灵枢》曰∶冲脉之别者，斜入踝，出属跗上，入大趾之间，注诸络，以温足胫，此脉之常动者也）。
（足背）〔中间部位〕归属于足阳明胃经（《灵枢》记载：足阳明胃经的经脉，沿着小腿外侧下行至足背，进入第二趾内侧间隙。又说：足背上方，脉搏坚硬下陷的，是足阳明经的病证，这是胃脉的表现。《素问》记载：身体沉重难以行走的，是因为胃脉在足部所致。张三锡说：冲阳穴，位于足背上五寸的凹陷处，突发昏厥且脉搏伏匿者，通过此穴可以救治，这就是所谓“有胃气”的表现）。又归属于足太阴脾经（《素问》记载：下部的人迎脉，对应足太阴经，用以候察脾胃之气。注释：胃脉在足背上的冲阳部位，搏动应于手指，用以候察胃气，同时兼候脾气。又说：饮食不下，舌根强硬；进食则呕吐，冷性泄泻，腹胀；溏泄痢疾，小便闭塞，病本在于脾。如果冲阳脉绝，属于死证，无法治疗）。〔内侧边缘〕归属于足厥阴肝经（《灵枢》记载：足厥阴肝经的经脉，起于大趾丛毛处，向上沿足背内侧缘上行。又说：阴中之少阳，即肝脏，其原穴出于太冲。太冲穴，位于足大趾上二寸的凹陷处，为输穴。《素问》记载：男子疝气，女子少腹疼痛，眼睛眯视，疮疡痤疮痈肿，病本在于肝。如果太冲脉绝，属于死证，无法治疗。沈承之说：足背上有太冲穴，一名冲阳，又名跗阳，位于两足背大趾与次趾本节后约二寸处，寻摸动脉凹陷中。穴中有脉搏跳动则生，无脉搏跳动则死。因为此穴是足厥阴经脉气所注之处，为肝之输穴；也是足阳明经脉气所经过之处，为胃之原穴。肝为生发之源，胃为五脏之本，因为它们能冲贯全身骨骼，营养各条经脉，所以称为“冲”。这两条经脉相互依存，没有肝死而胃独存，或胃绝而肝犹在的情况。所以虽然异经但同穴，不必区分究竟属肝还是属胃。然而必须诊察太溪穴，以参考决断。顾英白说：太冲是足厥阴经的输穴，冲阳是足阳明经的原穴，这两个穴位虽然相近，但实际上各不相同。至于胆经的跗阳穴，又在外踝之上，承接它们合而为一，这是我不能理解的地方。冲阳本属胃经，却兼用来候察脾经的绝症，脾与胃相表里，后人为何要主观臆断、自以为是呢）。〔外侧边缘〕归属于足少阳胆经（《灵枢》记载：足少阳胆经的经脉，沿足背上行，进入小趾与次趾之间；其分支，从足背分出，进入大趾之间。又说：足少阳经的别络，名叫光明，距离外踝上五寸，别走足厥阴经，向下联络足背。实证表现为厥逆，虚证表现为痿软，坐立困难，取用该别络进行治疗）。又归属于冲脉（《灵枢》记载：冲脉的别络，斜入踝部，外出归属足背，进入大趾之间，注入各络脉，以温煦足胫，这是脉气常动的表现）。
(The dorsum of the foot) [The middle part] belongs to the Foot-Yangming Stomach Meridian (Ling Shu states: The meridian of Foot-Yangming runs along the lateral aspect of the lower leg, descends to the dorsum of the foot, and enters the medial space between the second toe. It also states: On the dorsum of the foot, where the pulse is hard and depressed, it indicates a disease of the Foot-Yangming meridian, which is the stomach pulse. Su Wen states: Heaviness of the body and difficulty in walking are due to the stomach pulse being located in the foot. Zhang Sanxi says: Chongyang acupoint (Chongyang, ST42), located in the depression five cun above the dorsum of the foot, can be used for rescue in cases of sudden syncope with a hidden pulse, which is what is meant by "having stomach qi".). It also belongs to the Foot-Taiyin Spleen Meridian (Su Wen states: The human pulse at the lower part corresponds to the Foot-Taiyin, used to observe the qi of the spleen and stomach. Note: The stomach pulse is located at Chongyang on the dorsum of the foot; its movement responds to the hand, used to observe the stomach, and simultaneously observes the spleen. It also states: Inability to eat, stiffness of the tongue root; vomiting after eating, cold diarrhea, abdominal distension; loose stools or dysentery, urinary obstruction; the root of the disease lies in the spleen. If the Chongyang pulse is absent, it is a death case that cannot be treated.). [The medial margin] belongs to the Foot-Jueyin Liver Meridian (Ling Shu states: The meridian of Foot-Jueyin originates from the hair tuft at the big toe, and ascends along the medial margin of the dorsum of the foot. It also states: Shaoyang within Yin is the liver; its Yuan-Source point originates from Taichong. Taichong, located two cun above the big toe in the depression, is the Shu-Stream point. Su Wen states: Hernia in men, lower abdominal pain in women, squinting eyes, sores, acne, and carbuncles; the root of the disease lies in the liver. If the Taichong pulse is absent, it is a death case that cannot be treated. Shen Chengzhi says: There is the Taichong acupoint on the dorsum of the foot, also known as Chongyang or Fuyang, approximately two cun posterior to the metatarsophalangeal joint of the big toe and second toe on the dorsum of both feet, found by palpating the arterial depression in the hollow. If there is a pulse in the acupoint, life is possible; if no pulse, death ensues. This is because this acupoint is where the Qi of the Foot-Jueyin meridian pours in, serving as the Shu point of the liver; and it is where the Qi of the Foot-Yangming meridian passes through, serving as the Yuan-Source point of the stomach. The liver is the source of growth and development, and the stomach is the foundation of the five zang organs. Because they can penetrate the entire skeleton and nourish all meridians, they are called "Chong" (Pulsation/Thrust). These two meridians are mutually dependent; there is no case where the liver dies while the stomach survives alone, nor where the stomach perishes while the liver remains. Therefore, although they are different meridians sharing the same acupoint, there is no need to distinguish whether it belongs to the liver or the stomach. However, one must diagnose the Taixi acupoint to make a reference decision. Gu Yingbai says: Taichong is the Shu-Stream point of the Foot-Jueyin meridian, and Chongyang is the Yuan-Source point of the Foot-Yangming meridian. Although these two acupoints are close, they are actually distinct. As for the Fuyang acupoint of the Gallbladder meridian, it is located above the lateral malleolus, connecting them to form one, which is something I cannot understand. Chongyang originally belongs to the Stomach but is also used to observe the absence of the Spleen pulse; since the spleen and stomach are exterior-interior related, why should later generations act subjectively and arrogantly?). [The lateral margin] belongs to the Foot-Shaoyang Gallbladder Meridian (Ling Shu states: The meridian of Foot-Shaoyang runs along the dorsum of the foot and enters the space between the little toe and the second toe; its branch diverges from the dorsum of the foot and enters the space between the big toe. It also states: The Luo-Connecting vessel of Foot-Shaoyang is named Guangming, five cun above the ankle, diverging to the Jueyin meridian and descending to connect with the dorsum of the foot. Excess conditions manifest as厥逆 (Jue-ni, reversal cold/heat), deficiency conditions manifest as Wei syndrome (flaccidity), inability to sit or rise, and treatment involves selecting the Luo-Connecting point.). It also belongs to the Chong Mai (Penetrating Vessel) (Ling Shu states: The Luo-Connecting vessel of the Chong Mai slants into the ankle, emerges to belong to the dorsum of the foot, enters the space between the big toes, pours into the various collateral vessels to warm the shins of the feet, and this is the normal movement of the vessel qi).
