TL;DR: Classical physiognomy reads moles by where they grow and by colour. The mole section of Thái thanh thần giám (太清神鑑) holds that moles in exposed places are mostly inauspicious and those in hidden places mostly auspicious, and that black as ink or red as cinnabar is good; on the body, a mole in the navel means a noble son, one on the nape means authority, one at mid-waist is a bad sign, and the shoulder has no separate line. Thần tướng toàn biên reads the back, shoulders, neck and belly by shape and puts the heart above appearance. This is a physiognomic convention, not a scientific conclusion.
How are moles defined in physiognomy?
Thái thanh thần giám (太清神鑑), a physiognomy book copied into the Tứ khố toàn thư (Complete Library of the Four Treasuries), opens its mole section, “黑痣部”, in volume 6 with a comparison: “夫黑痣者若山之生林木地之出堆阜”, moles on a person are like trees growing on a mountain or mounds rising from the ground. A mountain of fine substance grows good trees and fouled ground grows ugly mounds; likewise a person of fine substance grows unusual moles that show nobility, and one of turbid substance grows bad moles that show lowliness. The book cites the Han founder Gaozu, who had seventy-two black moles on his left thigh (“漢高祖左股有七十二黑子”), as an imperial omen.
Two layers need separating. Medically, a mole is a benign pigmented lesion of the skin that anyone can have; how many a person has depends on heredity and sun exposure. In physiognomy, each spot is assigned an auspicious or inauspicious meaning; that is the convention of one school, not a statement about real people.
Why do physiognomy books distinguish hidden moles from exposed moles?
The founding principle sits in the same section: “凡黒痣生於顯處者多凶生於隠處之中者多吉”, moles in exposed places are mostly inauspicious and moles in hidden places mostly auspicious, so the book concludes that moles on the face are all unfavourable. The back and belly are usually covered by clothing and so count as hidden; the neck and nape are exposed, but as shown below, the book does not put every mole on the neck in the inauspicious group.
On colour, the book says “黑如墨赤如硃善也”: black as ink or red as cinnabar is good. A reddish tinge means quarrels and disputes (“帶赤色者主口舌鬪競”), a whitish tinge means worry and punishment (“帶白色者主憂刑”), and a yellowish tinge means forgetting and losing things (“帶黄色者主遺忘失脫”). Colour combines with position to form one judgment.
How are moles on the neck and shoulders read?
Thái thanh thần giám has a separate passage on moles of the body, “身體上下黑痣”, and there the neck is not wholly a bad spot. A mole just below the Adam's apple, near the top, is called the heavenly pillar and means being lifted up by others (“咽喉下近上者謂之天柱主得人提擕”); one lower down means death by injury. A mole on the nape is called the source of power and means authority (“項上謂之勢源主有威權之吉”).
Vietnamese folklore has its own saying. Phan Kế Bính records it in Việt Nam phong tục among the physiognomy sayings passed down orally: “A mole on the neck is a hole of buried money, a mole on the hand means borrowing all one's life.”[1] The book only records the saying without explaining it; read literally, it links a neck mole to a place where money is buried and does not call it a sign of losing money.
For the shoulder, the body passage of Thái thanh thần giám has no separate line. The statement “There is a red mole on the shoulder blade. This is an extremely noble sign.” appears in popular Vietnamese physiognomy books such as Xem tướng biết người, not in the mole section of Thái thanh thần giám. Lam Sơn thực lục describes the young Lê Lợi as having “seven moles on his left shoulder”, and says “the discerning knew he was a man of the highest rank”; that is a historical record about one person, not a rule of the physiognomy books.
What do moles on the back and belly mean?
The belly has the most lines in the body passage of Thái thanh thần giám. A mole in the middle of the navel is called the dragon gate and means blessings, wisdom and the birth of a noble son (“臍中謂之龍闗主福智生貴子”); on either side below the navel it means rank and happiness (“臍下兩傍謂之左荒右野主貴而樂”); on either side of the belly's horizontal crease it means a leisurely, refined nature, wealth and joy (“腹横紋兩傍謂之逸堂主性閑雅富貴快樂”). For the back, the passage mentions only the waist: a mole at the very centre of the waist is called the four great seas and means holding office at a frontier post and dying there without returning (“腰當中心謂之四大海主守官邊庭不返而死”). So even in a hidden place, a mole at mid-waist is read as a bad sign.
Thần tướng toàn biên discusses the back, shoulders, neck and belly in its seventh method of observation, “七取腰圆背厚”, but by shape, not by moles: a thick, broad back and a round, firm waist are good; it dislikes a spine sunk into a groove, a thin back with drooping shoulders, and raised shoulders with a thin neck (“最嫌背脊成坑，背薄肩垂，肩昂颈削”); the belly should have a pouch like a gourd (“腹宜有囊如葫芦”). The book quotes “背负三山如护甲，脐深纳李腹垂箕，如此之相必大贵”: a back as if carrying three mountains, like wearing armour, a navel deep enough to hold a plum, a belly hanging like a winnowing basket, such a person is bound to be greatly noble.
How do the physiognomy books differ?
What they share is treating moles and body shape alike as signs for reading fortune. They differ in what each book looks at.
| Book | How it reads | Focus |
|---|---|---|
| Thái thanh thần giám (太清神鑑), section 黑痣部 | Exposed mostly inauspicious, hidden mostly auspicious; black as ink, red as cinnabar is good; lists moles spot by spot on the head and face, hands and feet, body | Principle, colour, position |
| Thần tướng toàn biên (traditionally attributed to Trần Đoàn, revised by Viên Trung Triệt) | Seventh method reads the waist, back, shoulders, neck and belly by shape; ninth method puts the heart above appearance | Shape and heart |
| Việt Nam phong tục (Phan Kế Bính, 1915) | Records folk sayings: a mole on the neck is a hole of buried money, a mole on the hand means borrowing all one's life | Folk sayings |
| Tướng mệnh khảo luận (Vũ Tài Lục) | Quotes old verses, stressing that one must add, subtract, weigh and balance | Methodology |
Vũ Tài Lục's Tướng mệnh khảo luận quotes the verse “Tướng vô quyết pháp bất khả loạn ngôn” and explains: one cannot call a person fine from a single point, nor call them ill-fated because of a single flaw; one must know how to add, subtract, weigh and balance.[2]
Why does physiognomy weight the heart more heavily than moles?
Thần tướng toàn biên opens with ten methods of observation (“十观”), and the ninth, on voice and heart (“九取声音与心田”), says that someone of plain appearance with a good heart will in the end be rich and honoured, while someone of imposing appearance with a treacherous heart, even if rich and honoured, will soon be poor (“若相貌堂堂，心事奸险，纵然富贵，不日贫穷”). The book goes on to quote: “有相无心相从心灭，有心无相相从心生”.
Phan Kế Bính in Việt Nam phong tục likewise quotes the physiognomy book of Ma Y to the same effect: “Hữu tâm vô tướng, tướng tùy tâm sinh; hữu tướng vô tâm, tướng tùy tâm diệt”, meaning that with a good heart but no good features, the features arise from the heart, and with good features but no good heart, the features vanish with the heart. He reads it as valuing the heart above appearance and calls it “a most reasonable saying”.[1] Side by side, the two passages show that within the physiognomic tradition itself, a mole is only a minor sign, ranked below the reading of the heart.
Nhật Nguyệt's suggestions for reading mole tables
Nhật Nguyệt's suggestion:
- Treat a mole as a prompt to reflect on how you deal with people, not as a verdict on your fate. The physiognomy books themselves say one must add, subtract, weigh and balance, so a single mole decides nothing.
- When reading a mole table, ask right away: which book is this line from, and does the book really say so? If the source is unclear, treat it as folklore, not as a record.
- For moles on the skin, what matters is medical monitoring: a mole that changes colour, grows quickly, bleeds, itches, or has an irregular border should be checked by a dermatologist. This is general medical advice and has nothing to do with physiognomy.
- To go deeper, read the 黑痣部 section of Thái thanh thần giám and the seventh and ninth methods of Thần tướng toàn biên directly, rather than a summary table.
