60昆仑经穴，属火。
别名：上昆仑。
名解：1)昆仑。昆仑，广漠无艮也。昆仑名意指膀胱经的水湿之气在此吸热上行。本穴物质为膀胱经经水的气化之气，性寒湿，由于足少阳、足阳明二经的外散之热作用，寒湿水气吸热后亦上行并充斥于天之天部，穴内的各个层次都有气血物存在，如广漠无艮之状，故名昆仑。上昆仑名意与昆仑同。
2)膀胱经经穴。经，经过也，动而不居也。本穴物质为天部的水湿之气，其运行变化为吸热上行，动而不居，故为膀胱经经穴。
3)本穴属火。属火，指本穴气血运行变化表现出的五行属性。本穴物质原本为天之下部的水湿之气，在本穴的变化为吸热后上行天之天部，表现出火的炎上特征，故其属火。
功能作用：散热化气。

[Name Explanation] "Huang" refers to the diaphragm below the heart. The name Mangmen (Blind Gate) indicates that the fatty substances carried by the Qi and Blood in the Heavenly Level cool and descend here. This acupoint corresponds to Gaohuang (Gallbladder Fat), which is the exit point for fatty substances, whereas this acupoint is the return point for these substances; hence it is named Mangmen (Blind Gate).
[Qi-Blood Characteristics] The Qi-Blood substance is condensed fat.
[Movement Pattern] Fatty substances cool and descend from the Heavenly Level to the Earthly Level.
[Functions and Effects] Accumulates lipids and reduces turbidity.
[Therapeutic Methods] For Cold patterns, apply moxibustion; for Heat patterns, use draining methods.
52 Zhishi (Will Chamber)
Aliases: Jinggong (Essence Palace).
[Acupoint Meaning] Cold-damp water Qi from the Kidney is transported outward to the Bladder Meridian here.
[Name Explanation] 1) Zhishi. "Zhi" refers to the Essence of the Kidney and Kidney Qi. "Shi" refers to the inner room of a house, opposite to the "Tang" (main hall); the Tang is in front, and the Shi is in the back. It also refers to the cold-damp water Qi transported outward from the Kidney within the acupoint. The name Zhishi indicates that cold-damp water Qi from the Kidney is transported outward to the Bladder Meridian here.
2) Jinggong. "Jing" refers to what the Kidney stores, i.e., Kidney Essence-Qi. "Gong" refers to a palace. The name Jinggong indicates that the subtle Qi derived from the gasification of Kidney fluids is transported outward to the Bladder Meridian here. The Qi-Blood substance of this acupoint originates from the gasified Qi of Kidney water. Most of it cools and descends to the Earthly Level, while only a small portion of clear Qi ascends to this acupoint after absorbing heat. Since the substance here is transformed from the subtle Qi of the Kidney, it is named Jinggong (Essence Palace).
[Qi-Blood Characteristics] The Qi-Blood substance is cool and damp water Qi.
[Movement Pattern] A small portion absorbs heat and ascends along the Bladder Meridian; the majority cools and descends to the Earthly Level and flows downward along the Bladder Meridian.
[Functions and Effects] Internally dissipates Heat from the Kidneys; externally lowers warmth on the body surface.
[Therapeutic Methods] For Cold-Damp patterns, perform pricking bloodletting, or use draining followed by tonifying methods, or tonifying combined with moxibustion. For Dry-Heat patterns, use needle-draining to release Qi or aquacupuncture.
53 Baohuang (Fetal Huang)
[Acupoint Meaning] Fatty substances from the Uterus are transported outward to the Bladder Meridian here.
[Name Explanation] "Bao" refers to the membranous sac enclosing the fetus; "Huang" refers to the diaphragm below the heart. The name Baohuang indicates that fatty substances from the Uterus are transported outward to the Bladder Meridian here. The substance of this acupoint comes from the fatty substances in the Uterus, which share the same nature as those transported outward from the diaphragm below the heart; hence it is named Baohuang. (Baohuang corresponds to Pangguangshu (BL 28); their sources of Qi-Blood are the same. Based on the analysis of previous acupoints, one might deduce that the substance here should be dry gaseous matter resulting from the gasification of the Bladder Fu-organ. Why is the substance here fatty? This is because the Qi-Blood substances of both Baohuang and Pangguangshu do not originate solely from the Bladder Fu but also from the Uterus. From the perspective of the human gravity field, the Bladder and the Uterus are at the same level and coordinate height, possessing similar Qi-Blood characteristics and exiting through the same outlet to the Bladder Meridian. However, the Qi-Blood transported from the Uterus contains more lipid components, whereas that from the Bladder contains more damp-water components. Due to different coordinate positions within the human gravity field, the Qi-Blood substances transported outward by Pangguangshu and Baohuang exhibit different characteristics. This explains why the Qi-Blood substance of Baohuang is primarily lipid-based rather than dry gaseous water.)
[Qi-Blood Characteristics] The Qi-Blood substance is fat/lipid.
[Movement Pattern] It cools and descends to the Earthly Level after dissipating heat in this acupoint.
[Functions and Effects] Accumulates lipids and dissipates heat.
[Therapeutic Methods] For Cold-Damp patterns, perform pricking bloodletting, or use draining followed by tonifying methods, or tonifying combined with moxibustion. For Dry-Heat patterns, use needle-draining to release Qi or aquacupuncture.
54 Zhibian (Rank Edge)
[Acupoint Meaning] Damp-watery Qi dissipating from the buttocks is transmitted to the Bladder Meridian here.
[Name Explanation] "Zhi" historically referred to the salary of officials; here it refers to Lung Metal Qi within the acupoint. This acupoint belongs to the Bladder Meridian. In Five Elements theory, Water acts as the official, and its "salary" is Metal Qi. "Bian" means side or edge. The name Zhibian indicates that damp-watery Qi dissipating from the buttocks is transmitted to the Bladder Meridian here. The substance of this acupoint is watery Qi generated from gasification in the muscle layers of the lower back and buttocks. Upon reaching this acupoint, it cools, shrinks, and travels along the Bladder Meridian. The cooled descending Qi supplements the Jing-Water of the Earthly Level of the Bladder Meridian; hence it is named Zhibian.
[Qi-Blood Characteristics] The Qi-Blood substance is watery Qi in the Heavenly Level, with a cool and damp nature.
[Movement Pattern] After dissipating heat and cooling into liquid water, it descends along the Bladder Meridian.
[Functions and Effects] Lowers temperature and generates water.
[Therapeutic Methods] For Cold patterns, use draining followed by tonifying or tonifying combined with moxibustion. For Heat patterns, use draining or aquacupuncture.
55 Heyang (Meeting Yang)
[Acupoint Meaning] Yang-Heat Qi absorbed and ascending from the Bladder Meridian gathers here.
[Name Explanation] "He" means meeting or gathering; "Yang" refers to Yang-Heat Qi. The name Heyang indicates that Yang-Heat Qi absorbed and ascending from the Bladder Meridian gathers here. The substance of this acupoint is formed by the gathering of Yang Qi ascending from the acupoints below the knee on the Bladder Meridian; hence it is named Heyang.
[Qi-Blood Characteristics] The Qi-Blood substance is Yang Qi in the Heavenly Level, with little dampness.
[Movement Pattern] It dissipates heat, cools, contracts, and transmits upward to Weizhong (BL 40).
[Functions and Effects] Dissipates heat and reduces turbidity.
[Therapeutic Methods] For Cold-Damp patterns, use tonifying combined with moxibustion. For Damp-Heat patterns, use needle-draining to release Qi.
56 Chengjin (Supporting Tendon)
Aliases: Shuchang, Zhichang.
[Acupoint Meaning] Ascending Yang Qi of the Bladder Meridian transforms into Wind and moves here.
[Name Explanation] 1) Chengjin. "Cheng" means to bear or support; "Jin" refers to Wind, which is governed by the Liver. The name Chengjin indicates that ascending Yang Qi of the Bladder Meridian transforms into Wind and moves here. The substance of this acupoint is Yang-Heat Qi ascending from the acupoints below the foot on the Bladder Meridian. Upon reaching this acupoint, it assumes a wind-like state; hence it is named Chengjin.
2) Shuchang. Shuchang refers to Zhichang. The name Shuchang indicates that the Qi-Blood substance of this acupoint shares the same characteristics as that of the Large Intestine Meridian. The substance here is Yang-Heat Qi ascending from the acupoints below the foot on the Bladder Meridian, rich in dampness and warm in nature, sharing the same nature as the Qi-Blood of the Large Intestine Meridian; hence it is named Shuchang.
[Qi-Blood Characteristics] The Qi-Blood substance is Yang-Heat Qi, with a warm nature.
[Movement Pattern] It ascends rapidly along the Bladder Meridian.
[Functions and Effects] Transforms and transports dampness.
[Therapeutic Methods] For Cold patterns, apply moxibustion. For Heat patterns, drain at Heyang (BL 55); needling is contraindicated.
Note: This acupoint is listed as contraindicated for needling in classical texts because the dampness in the lower part of the Bladder Meridian relies on this acupoint for transformation. Needling would stop the movement of Wind and Qi, preventing the transformation of dampness in the lower Bladder Meridian; thus, it is listed as contraindicated.
57 Chengshan (Supporting Mountain)
Aliases: Yufu, Rouzhu, Shangshan, Yuchang, Changshan, Yufushan, Yuzhu, Yuyao.
[Acupoint Meaning] Spleen Earth particles descending with the Jing-Water of the Bladder Meridian solidify here.
[Name Explanation] 1) Chengshan. "Cheng" means to bear or support; "Shan" refers to large piles of earth and stone, indicating that the substance in this acupoint is Spleen Earth. The name Chengshan indicates that Spleen Earth particles descending with the Jing-Water of the Bladder Meridian solidify here. The substance of this acupoint is a mixture of Spleen Earth and water ascending with the Jing-Water of the Bladder Meridian. Upon reaching this acupoint, the water vaporizes, and the dried Spleen Earth particles settle around the acupoint. These settled particles accumulate like a large mountain; hence it is named Chengshan.
2) Yufu. This describes the characteristics of the Qi-Blood in the acupoint from a morphological analogy. The substance here is Spleen Earth washed down by the Jing-Water of the Bladder Meridian, accumulating in the acupoint like the plump muscles of a fish's belly; hence it is named Yufu (Fish Belly). The names Yufushan, Yuchang, and Yuyao have meanings similar to Yufu.
3) Rouzhu. "Rou" refers to Earth governed by the Spleen; "Zhu" means pillar. The name Rouzhu indicates that Spleen Earth substance in the Qi-Blood of the Bladder Meridian accumulates here. The substance here consists of Spleen Earth particles washed down by the Jing-Water, which are dry and accumulate in the acupoint, possessing significant load-bearing capacity; hence it is named Rouzhu. The name Yuzhu has the same meaning as Rouzhu.
4) Shangshan. "Shang" means injury; "Shan" refers to large piles of earth and stone. The name Shangshan indicates that the Yang-Heat Wind Qi ascending on the Bladder Meridian causes significant damage to the solidified Spleen Earth particles in this acupoint. The substance here is dry Spleen Earth particles, while Yang-Heat Wind Qi from the Bladder Meridian passes through this acupoint. If the Spleen Earth particles lack sufficient moisture, they will be blown away and damaged by the ascending Wind Qi; hence it is named Shangshan.
[Qi-Blood Characteristics] The Qi-Blood substance consists of Earthly Level Spleen Earth and Heavenly Level ascending Wind Qi.
[Movement Pattern] Wind Qi ascends along the Bladder Meridian, while Spleen Earth remains fortified around the acupoint.
[Functions and Effects] Transforms and transports dampness; solidifies Spleen Earth.
[Therapeutic Methods] For Cold-Damp patterns, use draining followed by tonifying or tonifying combined with moxibustion. For Wind-Heat patterns, use draining or aquacupuncture.
58 Feiyang (Flying Yang) [Luo-Connecting Point]
Aliases: Jueyang, Jueyin, Jueyang.
[Acupoint Meaning] Qi-Blood of the Bladder Meridian absorbs heat and flies upward here.
[Name Explanation] 1) Feiyang. "Fei" refers to Qi in the Heavenly Level within the acupoint; "Yang" refers to rising and moving upward. The name Feiyang indicates that Qi-Blood of the Bladder Meridian absorbs heat and ascends here. The substance of this acupoint is damp-watery Qi ascending from the acupoints between Fuyang (BL 59) and Zhiyin (BL 67) on the Bladder Meridian. Its change in this acupoint involves further absorption of heat and steaming ascent; hence it is named Feiyang.
2) Jueyang. "Jue" is interchangeable with "Jue," meaning to rise up or dig up; "Yang" refers to Yang Qi. The name Jueyang indicates that Qi-Blood of the Bladder Meridian rises and ascends here. The principle is the same as for Feiyang. The names Jueyin and Jueyang have meanings similar to Jueyang. "Yin" indicates that the Qi-Blood substance ascending in this acupoint is cold-damp water Qi of the Bladder Meridian, not true Yang-Heat Qi.
3) Bladder Meridian Luo-Connecting Point. The Qi-Blood of this acupoint is damp-watery Qi ascending after absorbing heat. It not only ascends along the Bladder Meridian but also diffuses outward to the Shaoyin Kidney Meridian, which is interiorly-exteriorly related to the Bladder Meridian; therefore, it serves as the Luo-Connecting Point of the Bladder Meridian.
[Qi-Blood Characteristics] The Qi-Blood substance is damp-watery Qi in the Heavenly Level, with a warm nature.
[Movement Pattern] The majority ascends along the Bladder Meridian; a small portion branches off to enter the Foot-Shaoyin Kidney Meridian.
[Functions and Effects) Connects the exterior and interior meridians.
[Therapeutic Methods] For Cold patterns, use tonifying. For Heat patterns, use draining.
59 Fuyang (Foot-Yang) [Xi-Cleft Point of Yang Qiao Mai]
Aliases: Fuyang, Fuyang.
[Acupoint Meaning] Yang Qi of the Foot-Shaoyang and Foot-Yangming Meridians drives the Qi-Blood of the Foot-Taiyang Meridian to ascend here.
[Name Explanation] 1) Fuyang. "Fu" refers to the dorsum of the foot; "Yang" refers to Yang Qi. The name Fuyang indicates that Yang Qi of the Foot-Shaoyang and Foot-Yangming Meridians drives the Qi-Blood of the Foot-Taiyang Meridian to ascend here. The Yang Qi ascending from the foot on the Bladder Meridian dissipates heat and transforms into cold-damp watery Qi upon reaching this acupoint. Because it receives heat supplementation from the ascending Yang Qi of the Foot-Shaoyang and Foot-Yangming Meridians, the damp-watery Qi of the Foot-Taiyang Bladder Meridian can continue to ascend. The ascent of damp-watery Qi in this acupoint relies on the Yang Qi ascending from the dorsum of the foot; hence it is named Fuyang. The names Fuyang and Fuyang have the same meaning as Fuyang. (Why do the Qi-Blood of the Foot-Shaoyang and Foot-Yangming Meridians intersect at this acupoint, yet classical texts do not refer to this acupoint as the Meeting of the Three Foot-Yang Meridians? This is because, in the human gravity field, this acupoint is located at a high elevation where muscles protrude. Therefore, the ascending Yang Qi of the Foot-Shaoyang and Foot-Yangming Meridians intersects here. Yang Qi moves upward and outward. However, the Yang Qi of these two meridians ascending to this acupoint is nominal rather than substantial; it is merely deficient Heat Qi, containing much heat but little Qi. Thus, classical texts do not describe this acupoint as the meeting of the three Foot-Yang Meridians.)
2) Xi-Cleft Point of the Yang Qiao Mai. "Xi" means pore or crevice. The substance of this acupoint is composed of Yang Qi ascending from the three Foot-Yang Meridians, and its Qi-Blood nature is similar to that of the Yang Qiao Mai. However, since the Yang Qi ascending to the Bladder Meridian here is relatively cold and damp, even with the driving force of the Yang Qi from the Foot-Shaoyang and Foot-Yangming Meridians, the amount of Yang Qi transported upward from this acupoint is small, resembling output from a pore; hence it is named the Xi-Cleft Point of the Yang Qiao Mai.
[Qi-Blood Characteristics] The Qi-Blood substance is Yang-Heat Qi.
[Movement Pattern] It transmits upward along the Bladder Meridian to Feiyang (BL 58).
[Functions and Effects] Absorbs heat and transforms dampness.
[Therapeutic Methods] For Cold patterns, use tonifying combined with moxibustion. For Heat patterns, use needle-draining to release Qi.
60 Kunlun (Jing-River Point, Belongs to Fire)
Alias: Shang Kunlun.
[Acupoint Meaning] Damp-watery Qi of the Bladder Meridian absorbs heat and ascends here.
[Name Explanation] 1) Kunlun. Kunlun means vast and boundless. The name Kunlun indicates that damp-watery Qi of the Bladder Meridian absorbs heat and ascends here. The substance of this acupoint is the gasified Qi of the Jing-Water of the Bladder Meridian, with a cold-damp nature. Due to the external dissipating heat of the Foot-Shaoyang and Foot-Yangming Meridians, the cold-damp watery Qi absorbs heat, ascends, and fills the upper Heavenly Level. Qi-Blood substances exist at all levels within the acupoint, resembling a vast and boundless expanse; hence it is named Kunlun. The name Shang Kunlun has the same meaning as Kunlun.
2) Bladder Meridian Jing-River Point. "Jing" means passing through, moving without staying. The substance of this acupoint is damp-watery Qi in the Heavenly Level. Its movement and change involve absorbing heat and ascending, moving without staying; therefore, it is the Jing-River Point of the Bladder Meridian.
3) This acupoint belongs to Fire. "Belongs to Fire" refers to the Five Elements attribute manifested by the movement and change of Qi-Blood in this acupoint. The substance of this acupoint originally was damp-watery Qi in the lower part of the Heaven. Its change in this acupoint involves absorbing heat and ascending to the upper Heavenly Level, manifesting the flaming-upward characteristic of Fire; hence it belongs to Fire.
[Qi-Blood Characteristics] The Qi-Blood substance is damp-watery Qi in the Heavenly Level.
[Movement Pattern] After absorbing heat, it ascends along the Bladder Meridian to the upper Heavenly Level.
[Functions and Effects] Dissipates heat and transforms into Qi.
[Therapeutic Methods] For Cold-Damp patterns, perform pricking bloodletting, or use draining followed by tonifying, or tonifying combined with moxibustion. For Wind-Heat patterns, use needle-draining to release Qi or aquacupuncture.
61 Pucan (Servant Bowing)
Aliases: Anxie, Anye, Anbang.
[Acupoint Meaning] A small portion of damp-watery Qi of the Bladder Meridian absorbs heat and ascends here.
[Name Explanation] 1) Pucan. Pucan means servants bowing. The name Pucan indicates that a small portion of damp-watery Qi of the Bladder Meridian absorbs heat and ascends here. This acupoint belongs to the Bladder Meridian, and the substance within is cold-damp watery Qi, with Water as the master and Fire as the servant. The hot Qi transmitted from outside can only vaporize and ascend a small portion of the damp-watery Qi to the Heaven. Relative to the cold-damp watery Qi in this acupoint, the hot Qi from outside is like a servant; hence it is named Pucan.
2) Anxie. "An" means stable or calm; "Xie" means pathogenic factor. The name Anxie indicates that the Hot Qi within the acupoint is weak in power. The substance of this acupoint is cold-damp watery Qi. The hot Qi transmitted from outside into the acupoint is considered pathogenic Qi (Xie). However, the hot Qi transmitted from outside is insufficient to change the cold-damp nature of the Qi-Blood within the acupoint; hence it is named Anxie. The names Anye and Anbang have the same meaning as Anxie.
