Quick Answer
LU9 Taiyuan, often remembered as Great Abyss, is a Lung meridian point at the wrist crease. It appears in breath-focused traditions, but breathing trouble, chest symptoms, wrist injury, pulse-area discomfort, numbness, or swelling should keep the page read-only.
Safety Decision
Stop before pressure if the body area is injured, the symptom is severe or unusual, or qualified care should come first.
Continue only as a short, comfortable, education-only routine after reading the locator and stop signs.
LU9 TaiyuanBefore You Try This
This LU9 page is educational and not medical advice. It cannot assess breathing symptoms, chest symptoms, wrist injury, pulse concerns, numbness, swelling, or whether pressure is suitable.
Ask qualified care for breathing trouble, chest symptoms, severe or persistent cough, fever, wrist injury, numbness, swelling, severe pain, medication questions, pregnancy, children, or chronic illness.

Is This the Right Page to Read Now?
This acupoint page fails if the Great Abyss on the wrist crease in the Lung family locator becomes a treatment shortcut, a stronger-pressure target, or a replacement for the named safety stop signs.
Read the wrist and breathing cautions, then compare LU7, sinus guide, PC6, or Safety. Then choose read-only, one brief comfortable contact, a printable card, or a safety stop.
Diagram Notes
The marker highlights LU9 Taiyuan, Great Abyss, on a wrist crease locator view; its landmark cue is "At the wrist crease on the thumb side, near a pulse-sensitive area." Use it with the safety cues rather than treating the marker as clinical precision.
Locator overlay for LU9 Taiyuan, Great Abyss, placed on CC BY 4.0 Servier Medical Art human anatomy base images and paired with a regional landmark view.
How to read the LU9 locator
- Start with the broad area: wrist crease.
- Compare the written landmark: At the wrist crease on the thumb side, near a pulse-sensitive area.
- Use the marker as orientation, then let comfort and the avoid heavy pressure over pulse-sensitive areas caution decide whether to stop.
The Great Abyss locator uses a licensed educational anatomy base for the wrist crease; it is not a clinical locator or personal safety clearance.
Why This Page Gets Extra Attention
Reader Scenario
A reader arrives at LU9 after seeing a short chart and needs to verify the Great Abyss landmark on the wrist crease before doing anything physical.
Common Misread
Do not use LU9 as a breath-focused hand routines shortcut; the locator and caution still decide whether this stays reading-only.
Editorial Call
Great Abyss earns its length only when it separates wrist crease touch, landmark confidence, breath-focused hand routines context, and the reason to stop.
Best Next Choice
Choose whether Great Abyss should stay read-only, allow one brief comfortable wrist crease contact, move to the printable card, or open a safety page.
Use the Great Abyss locator as a neighborhood check for the wrist crease; the written landmark still outranks the marker.
LU9 Taiyuan and the Great Abyss name
LU9 is the standard code for Taiyuan, often translated as Great Abyss. The name belongs to traditional point vocabulary and Lung meridian context. It does not turn the wrist crease into a breathing or chest-symptom page.
Wrist crease location needs pulse-area caution
LU9 sits near the wrist crease and pulse-sensitive tissue. Heavy pressure, sharp pain, numbness, swelling, injury, skin irritation, or discomfort over the pulse area should stop pressure. The locator is broad, not a clinical placement.
Where LU9 fits in breath and sinus pages
LU9 can appear near LU7 and sinus pages because of Lung-family vocabulary. In public content, that relationship stays educational. Breathing trouble, chest symptoms, fever, severe illness, or worsening symptoms leave the point path.
How LU9 relates to LU7 and PC6
LU7 is the thumb-side forearm comparison. PC6 is a Pericardium wrist page linked with nausea and travel context. LU9 sits in the wrist but has different meridian language and pulse-area caution. The reader should not treat all wrist points as interchangeable.
The wrong way to read LU9
The wrong reading is: Lung meridian plus wrist crease means LU9 is relevant for breathing problems. A safer reading is: LU9 is a named point, and actual breathing or chest symptoms belong outside self-pressure browsing.
Technique boundaries for LU9
This page does not teach acupuncture, moxa, cupping, scraping, pressure dosing, respiratory care, wrist care, or pulse interpretation. It explains naming, broad location, relationships, and stop signs.
Best next page after LU9
Choose LU7 for a forearm Lung-family comparison, the sinus guide for mild nasal context, or PC6 for nausea/travel wrist context. Choose Safety when breathing, chest, fever, wrist, numbness, or pulse-area concerns appear.
Full-page decision frame for LU9
LU9 Taiyuan, Great Abyss, deserves more than a chart label because the reader has to make several separate decisions before touching the wrist crease. The first decision is identity: this is a Lung point, not a general label for every nearby tender place. The second decision is context: breath-focused hand routines is a traditional or wellness reading cue, not a promise that pressure changes a personal condition. The third decision is safety: avoid heavy pressure over pulse-sensitive areas. A full page for Great Abyss therefore has to slow the reader down. It names the point, describes the broad locator, explains why the point appears with certain routines, separates acupressure from professional techniques, and gives a conservative next page. If the reader only wants a quick answer, the safest quick answer is still narrow: read the locator, check the stop signs, and use the point only as education unless the situation is mild and comfortable.
How to verify the wrist crease landmark
LU9 starts with the wrist crease view, but the visual marker is only a region finder. The written landmark carries the real work: At the wrist crease on the thumb side, near a pulse-sensitive area. Use light contact and do not apply heavy pressure over the pulse. This matters for Great Abyss because readers often arrive after seeing a short social post, wrist band, point chart, or routine list. A chart can make the target look cleaner than a real body feels. The reader should first name the broad body area, then compare the landmark with bones, tendons, folds, or soft tissue nearby, then check whether the skin and sensation are normal. If the reader cannot repeat the landmark in plain English, LU9 should remain a reading page. If the body area is painful, numb, swollen, bruised, hot, wounded, recently injured, or hard to interpret, the locator has already done its job by telling the reader to stop.
What breath-focused hand routines means on this page
The phrase breath-focused hand routines explains why LU9 appears in this atlas, but it does not turn Great Abyss into a personal answer. For Taiyuan, the use context is a signpost for reading related pages, not a guarantee, not a ranking, and not a reason to ignore symptoms. A better way to read the phrase is: people commonly encounter this point while researching breath-focused hand routines, so the page should explain the name, locator, safety limits, and nearby choices clearly. That is very different from saying the point handles the concern. If the concern is mild and ordinary, LU9 can be part of a conservative reading path. If the concern is severe, new, persistent, frightening, pregnancy-related, medication-related, child-related, post-surgery, or connected with chronic illness, the breath-focused hand routines phrase becomes less important than the safety path.
How LU9 relates to nearby point pages
Great Abyss should be compared with related pages only one relationship at a time. Useful comparison points include LU7 Lieque (thumb-side forearm), PC6 Neiguan (inner forearm), HT7 Shenmen (wrist crease), TE5 Waiguan (outer forearm). The relationship may come from the same meridian, the same body region, a similar routine page, or a shared beginner question, but those relationships do not make the points interchangeable. LU7 Lieque has its own locator and caution; PC6 Neiguan has another. For LU9, the right comparison question is not "which point is stronger?" but "which page answers my current job?" A culture page explains the name. A printable page preserves memory. A wellness page compares a mild scenario. A safety page interrupts action. Reading those pages in the right order keeps Taiyuan from becoming one more item in a long, unfocused list.
When pairing LU9 with another point makes sense
Pairing LU9 with another point is a reading decision before it is a physical routine. The safest pairing starts on a guide such as Acupressure for Sinus Pressure and Nasal Congestion, where the page can explain why several points appear together and which stop sign controls the whole set. For Great Abyss, pairing is most useful when it clarifies roles: one point may be the main locator to read, another may be a comparison point, and another may be a reason to leave the routine for Safety. Pairing is not useful when it simply adds more body areas because more points sound more complete. Each added point adds a new landmark, new tissue, and a new way to misread discomfort. If the reader cannot explain why LU9 belongs with the next point, the better step is to read one full page and stop.
Using LU9 inside a short routine
Great Abyss may appear in a mild self-care reading path, but the routine has to stay education-first and stop-first. A short routine around LU9 should have a beginning, a check, and an end. The beginning is the safety review: avoid heavy pressure over pulse-sensitive areas. The check is the locator review: At the wrist crease on the thumb side, near a pulse-sensitive area. The end is a conscious decision to stop, continue reading, or open a related page. If gentle contact is appropriate, it should stay brief, comfortable, and easy to release. The reader should not chase a deep ache, try to create sensation, or keep pressing because a point name sounds important. A routine also should not stack LU9 with every point on the Lung line. The page works best when it turns a vague impulse into one narrow action: read, locate broadly, touch lightly only if low risk is clear, and stop if the body gives any reason to stop.
Acupuncture, moxa, and cupping boundaries for LU9
LU9 can appear in professional acupuncture, moxibustion, or cupping contexts, but this page does not teach those methods. Acupuncture involves needles and belongs with qualified professional practice. Moxibustion involves heat, smoke, fire, burn risk, and pregnancy caution. Cupping involves suction, bruising, skin status, blood-thinner concerns, and injury questions. Those techniques are not stronger home versions of acupressure. For Great Abyss, the public page can explain that the same named point may appear across modalities, but it cannot convert professional technique language into instructions. If a reader came here searching for needling effects, moxa application, cupping placement, or stronger results, the safe answer is to stay in education mode and use qualified care or a licensed practitioner rather than improvising on the wrist crease.
Wrong turns readers make with Great Abyss
A frequent wrong turn is to treat tenderness near LU9 as proof that the point was found. Tenderness can mean pressure is too strong, the tissue is irritated, or the wrong body area is being tested. Another wrong turn is to use breath-focused hand routines as a shortcut around safety. A third is to keep moving across the wrist crease until something feels intense. For Great Abyss, intensity is not the goal. Clarity is the goal. The reader should be able to say: this is the Lung point Taiyuan, the locator is At the wrist crease on the thumb side, near a pulse-sensitive area., the caution is avoid heavy pressure over pulse-sensitive areas, and my next step is either read-only, gentle and brief, a related page, or qualified help. If that sentence cannot be said honestly, the page has not cleared pressure.
When LU9 is not the right next page
LU9 is not the right next page when the reader is trying to decide whether a symptom is serious, whether medicine can be changed, whether pregnancy or child use is safe, or whether an injury can be worked around. It is also not the right page when skin, tendon, pulse-sensitive tissue, numbness, swelling, bruising, or uncertainty is present. In those cases, opening more point pages can create false momentum. The better route is a safety page, a professional conversation, or emergency guidance when warning signs are present. The value of the Great Abyss article remains intact even when the answer is not to press. It still gives language, location context, visual orientation, and relationships. A high-quality point page is allowed to say that the most useful next action is leaving the point page.
How the printable card should depend on this page
The printable LU9 card should be treated as a reminder after this full article, not as the article itself. A card can remember Taiyuan, Great Abyss, the broad wrist crease cue, and the stop signs, but it cannot carry the full context around breath-focused hand routines, related points, source limits, or technique boundaries. For LU9, the card is useful when the reader has already read the landmark and wants a small memory aid. It is not useful when separated from the safety note, used during a high-risk situation, or shared as a quick instruction. If a card and the full page disagree in the reader's mind, the full page wins. If the card makes the action feel too easy, return to the full page or Safety.
Source and visual notes for Great Abyss
The source notes on LU9 have different jobs. Nomenclature and location sources keep LU9 Taiyuan aligned with standard naming and broad locator language. Safety and health-information sources keep the page from becoming personal advice. The visual source identifies the licensed anatomy base used for orientation; it does not prove exact placement on any reader's body. For Great Abyss, that split is important because source lists can look more authoritative than they are. A source can support a name, a boundary, a cultural context, or a visual credit, but it cannot inspect the reader, confirm a symptom, clear an injury, or promise that breath-focused hand routines will improve. The trustworthy reading is modest, traceable, and limited.
Final choice after reading LU9
End the Great Abyss page with one of four choices. Choice one is read-only: the reader understands LU9 better but does not touch the wrist crease. Choice two is a brief gentle contact: the situation is mild, the skin and tissue feel normal, the landmark is clear, and the reader can release immediately. Choice three is a related page: the reader needs Acupressure for Sinus Pressure and Nasal Congestion, a name-meaning page, a printable memory aid, or a safety answer before acting. Choice four is qualified care: the concern is personal, severe, persistent, unusual, pregnancy-related, medication-related, child-related, chronic-condition-related, injury-related, or unclear. The page is successful when the reader can choose among those outcomes without relying on a chart alone. LU9 is a named point, but the decision is the real product.
Relationship map after LU9
LU9 should leave the reader with a relationship map, not just a locator. Start with the point itself: Taiyuan, translated here as Great Abyss, sits in the Lung context and uses the wrist crease cue. Then compare neighboring reading paths: LU7 Lieque on the thumb-side forearm; PC6 Neiguan on the inner forearm; HT7 Shenmen on the wrist crease; TE5 Waiguan on the outer forearm; LI4 Hegu on the back of hand. Those pages are not backup targets to press if LU9 feels uncertain; they are separate articles with separate body areas, cautions, and purposes. The broader use-case map is Acupressure for Sinus Pressure and Nasal Congestion. Use those pages only when the concern is mild enough to remain in education and safety navigation. This map is important because many people search for a point by discomfort, then keep adding pages until something feels persuasive. A better habit is to ask which relationship explains the next decision. If the next decision is name meaning, open Culture. If it is a memory aid, open Printable. If it is a combination, open the matching wellness guide. If it is risk, leave LU9 for Safety. The map keeps Great Abyss from becoming a loose claim about breath-focused hand routines.
What the reader can safely take away from LU9
A careful takeaway from LU9 has five parts. First, remember the identity: LU9 Taiyuan, Great Abyss, is a named point, not a universal body button. Second, remember the place: At the wrist crease on the thumb side, near a pulse-sensitive area. Third, remember the caution: avoid heavy pressure over pulse-sensitive areas. Fourth, remember the use-language limit: breath-focused hand routines explains why the point appears in traditional and wellness reading paths, but it cannot decide a personal symptom or promise an outcome. Fifth, remember the next action: read only, use a brief gentle contact only when low-risk context is obvious, compare one related page, or ask qualified care. This takeaway is intentionally practical. It gives the reader something to do with the page without turning the page into medical advice. For Great Abyss, the best result is not that the reader presses more confidently. The best result is that the reader can explain why this point fits, why it does not fit, or why the question belongs outside the atlas today.
What sources support beside the evidence note for LU9
Reader use: for LU9 Taiyuan, the recalled sources support the exact article identity at /acupoints/lu9-taiyuan/, the displayed point name, and the broad locator language used on this page rather than a generic chart. Reader use: for LU9 Taiyuan, the named sources support the page-specific boundary "This LU9 page is educational and not medical advice. It cannot assess breathing symptoms, chest symptoms, wrist injur..." and the article value "A wrist Lung meridian article that explains pulse-area caution before any breath-language relationship." without promising a result. Read these notes as traceability for this one point page; they cannot inspect the reader's skin, medication, pregnancy status, chronic illness, pain pattern, urgency, or whether pressure belongs today.
Questions Readers Usually Ask
Can LU9 help breathing?
This site does not make that claim. Breathing trouble and chest symptoms belong outside acupressure routines.
Can I press LU9 over the wrist pulse?
Avoid heavy pressure or any pressure that feels sharp, numb, swollen, injured, or uncomfortable over pulse-sensitive tissue.
Is LU9 the same as PC6 because both are wrist points?
No. They are different points with different meridian context, related pages, and safety emphasis.
