Plot synopsis from Lĩnh Nam Chích Quái
Part A — The Yin King legend and Thôi Lượng’s piety
The Vietnamese Well lies in the Trâu Sơn region of Vũ Ninh district.
During the reign of the third Hùng Vương, the Yin (Shang) dynasty launched an invasion of the southern kingdom, garrisoning troops below Trâu Sơn mountain. Hùng Vương prayed to Lạc Long Quân, who manifested as Đổng Thiên Vương (the Heavenly King of Sóc), rode an iron horse into battle and routed the Yin army. The Yin King died at the foot of the mountain and became sovereign of the underworld. The people built a temple in his honor, but over time it fell to ruin.
From the Zhou through the Qin dynasty, a Vietnamese man named Thôi Lượng served the Qin court as Grand Censor (Ngự sử đại phu). Passing through the area and moved by the temple’s decay, he restored the shrine and inscribed a poem:
Cổ nhân truyền đạo thị Ân Vương / Tuần thú đương niên đáo thử phương / Sơn tú thủy lưu không kiến miếu / Tinh thăng tích tại thượng văn hương / Nhất triều thắng bại vô Ân đức / Vạn tải Uy Linh trấn Việt Thường / Bách tính tùng tư giai phụng tự / Mặc phù quốc tộ vĩnh vô cương.
The poem — a regulated seven-syllable octave pairing “Việt Thường” against “Ân đức” and “Uy Linh” against “quốc tộ” — is among the earliest embedded poems in Vietnamese narrative prose.
Later, the generals Nhâm Ngao and Triệu Đà brought troops south, garrisoned at Trâu Sơn, and had the temple restored and properly venerated.
Part B — Thôi Vỹ: mugwort, the deep well, the underworld palace
The Yin King, grateful for Thôi Lượng’s piety, sent the immortal Ma Cô to find him. Lượng had already died; only his son Thôi Vỹ survived.
During a Lantern Festival, a temple-goer offered a pair of crystal vases. Ma Cô — disguised in tattered robes — picked one up, accidentally dropped and shattered it, and was beaten by the crowd. Thôi Vỹ gave his own coat to pay her debt. Recognizing the son of Grand Censor Thôi, Ma Cô gifted him a bundle of magic mugwort: “Keep this safe. If you see anyone with a tumor, use it to heal them — wealth will follow.”
Vỹ healed his friend, the Daoist practitioner Ứng Huyền, instantly. Huyền then introduced him to Nhâm Ngao, who also suffered from a tumor. Cured, Nhâm Ngao adopted Vỹ, enrolled him in school. Nhâm Ngao’s daughter Phương Dung fell in love with Vỹ. His son Nhâm Phu, jealous, plotted to sacrifice Vỹ to the god Xương Cuồng. Phương Dung smuggled a knife to Vỹ; he tunneled out and fled into the night.
Rushing uphill, Vỹ slipped and plunged into a deep cavern. Inside: a stone altar, stalactites, and a colossal white serpent — golden crest, red mouth, red whiskers, white scales, a hundred fathoms long, a tumor on its neck, golden characters “Ngọc Kinh Tử Xà” inscribed on its forehead. The serpent moved to devour him. Vỹ knelt and offered to heal the tumor. A glowing ember fell from above; Vỹ lit the mugwort and cauterized the growth. The tumor vanished. The serpent coiled before him, inviting Vỹ to climb onto its back, and carried him up to the cave mouth.
Lost on the mountain, Vỹ stumbled upon a walled city with a gate roofed in red tile and a crimson plaque in gold characters: “Yin King City” (殷王城). Within: a pond of five-colored lotus, rows of sophora and willow, jade palaces, golden beds with silver mats, a pair of zither and se. Vỹ tried the strings. Hundreds of golden boys and jade maidens appeared, attending the Yin Queen. She invited him up to the dais, recounted how Thôi Lượng had restored the temple, and hosted a banquet.
Suddenly a long-bearded, pot-bellied man ascended and announced: “On the third of the first month, the northerner Nhâm Ngao was slain by the god Xương Cuồng.”
The Yin Queen dispatched “Lord Dương” to escort Vỹ back to the mortal world. Lord Dương told Vỹ to close his eyes and sit on his shoulders. Within half an hour they reached the summit. Lord Dương turned into a stone goat — still standing, says the tale, behind the Việt Vương temple on Trâu Sơn.
Part C — Ma Cô bestows a bride and the Long Tụy jade
Vỹ returned to Ứng Huyền’s home and recounted everything. On the night of the first of the eighth month, Ma Cô arrived leading a young woman, betrothed her to Vỹ, and presented the Long Tụy jade.
The Long Tụy jade comprised a paired male and female gem, handed down from the Yellow Emperor through the Yin dynasty. During the battle at Trâu Sơn the Yin King wore the jade and died; the gem was buried, yet its radiance still pierced the heavens. During the wars of the Qin, every treasure was burned — but “people read the spirit-energy and knew the precious Long Tụy jade remained in the southern land,” and came from afar seeking it. Now the Yin King used it to repay his debt to Vỹ. Contemporaries offered gold, silver, and silk worth hundreds of thousands in coin. Vỹ grew immensely wealthy.
Later, Ma Cô came to lead the couple away — where, no one knows. The well has since dried up, collapsed into a hollow, its traces hidden on Trâu Sơn. Locals call the site Việt Tỉnh Cương (越井岡 — the Well Ridge of Việt).
Three-layer narrative structure
The tale is a three-layer composite stitched together by a cross-generational grace-repayment chain:
Layer 1 — Indigenous Việt legend. The Hùng Vương – Yin war, Thánh Gióng’s iron horse, the Yin King dying and becoming underworld sovereign, Trâu Sơn as sacred ground. Links to Truyện Đổng Thiên Vương (tale 7) — both recount the Yin King’s death at Trâu Sơn.
Layer 2 — Qin–Triệu historical layer. Thôi Lượng as Qin Grand Censor, Nhâm Ngao and Triệu Đà bringing troops south, Nhâm Ngao killed by the god Xương Cuồng. Links to Truyện Mộc tinh (tale 4) — same god, same victim — and Truyện Kim Quy (tale 13) — Triệu Đà’s destruction of the An Dương Vương kingdom.
Layer 3 — Daoist fantastic layer. Ma Cô immortal (origin: Ge Hong’s Shenxian zhuan, 4th c.), the Long Tụy jade from the Yellow Emperor era, the well-to-otherworld motif (cf. Bùi Hàng truyện, Tang dynasty), the divine white serpent, the stone-goat transformation, the couple “departing to an unknown place” (implied transcendence).
The three layers are bound by the Thôi Lượng – Thôi Vỹ (father–son) pair: Lượng restores the Yin temple (layers 1+2) → Yin King sends Ma Cô in gratitude (layer 3) → Ma Cô gives mugwort (layer 3) → Vỹ heals Nhâm Ngao (layer 2) → Vỹ falls into the well (layer 3) → meets the Yin Queen (layers 1+3) → learns of Nhâm Ngao’s death (layer 2) → receives the Long Tụy jade (layers 1+3).
Two readings — “virtue rewarded” and “royal qi migrates south”
Reading 1: the moral of benevolent living
Trần Đình Hoành (commentary, dotchuoinon.com, 2015) reads the tale as ethical instruction:
Death dissolves all enmity. The Yin King was an enemy in life; in death, the Vietnamese worship him as a god. “Nhất triều thắng bại vô Ân đức” — one turn of victory or defeat, and all debts are settled. Generosity toward the dead enemy, reverence for the divine, compassion for the wretched — that is the way.
Virtue’s transformative power radiates outward. First Vỹ heals a friend (Ứng Huyền), then a foreign overlord (Nhâm Ngao), then the serpent king itself. Even within the enemy’s household, where one son (Nhâm Phu) plots murder, another figure (Phương Dung) protects.
The virtuous person turns misfortune into fortune. Vỹ falls into the well — seemingly to his death — yet meets the serpent god, heals it, reaches the Yin Queen’s palace. Meanwhile the wicked Nhâm Phu’s own father (Nhâm Ngao) is slain by the god Xương Cuồng.
Reading 2: royal qi (vương khí) transfers south
Read through a political-symbolic lens:
The Long Tụy jade — heirloom of the Yellow Emperor and the Yin dynasty, i.e. the legitimate royal charisma of China itself — lies buried at Trâu Sơn yet its radiance reaches heaven. “People read the spirit-energy and knew the jade remained in the southern land.” Implication: dynastic legitimacy has shifted from North to South.
Yin King City underground is not a hell but a paradise — jade palaces, five-colored lotus, golden beds. The Yin King, though defeated, reigns as a king. Vietnamese earth sustains even northern royal spirits.
Nhâm Ngao is slain by a local god. Northerners on Vietnamese soil must submit to indigenous deities. The Đại Việt Sử Ký Toàn Thư softens this: “offended the local earth spirit and fell ill, had to withdraw.” LNCQ chooses “struck dead” — unambiguous.
Thôi Lượng — “a man of our country” serving as Qin Grand Censor — mirrors Lý Ông Trọng (tale 11) as Qin Prince Consort. Implication: the Qin relied on Vietnamese talent at the highest levels; the Qin too was, in a sense, a Vietnamese dynasty.
The two readings are not mutually exclusive. The tale functions simultaneously as moral instruction (Trần Đình Hoành) and as a political statement about southward qi-migration. Nguyễn Huệ Chi regards LNCQ’s “marvelous-strange” (kì ảo) character as the bridge to the literary truyền kỳ genre exemplified by Nguyễn Dữ’s Truyền kỳ mạn lục — a blend of folkloric mythology and deep political-cultural symbolism.
Geography — Trâu Sơn, Vũ Ninh, Việt Tỉnh cương
Modern location
The Đại Nam Nhất Thống Chí (Nguyễn-dynasty gazetteer), Bắc Ninh province, “Mountains and Rivers” section, records: “Trâu Sơn, also called Vũ Ninh mountain,” and cites the Ming-era An Nam Chí: “Vũ Ninh mountain in Vũ Ninh district has the Tỉnh cương (Well Ridge) and a Stone Serpent called Ngọc Kinh Tử, as well as the tomb of the Việt King.”
A minor localization dispute exists:
(a) Vũ Ninh ward, Bắc Ninh city — local government sources and Vũ Vĩnh Trinh’s Nguyễn-era poem “Trâu Sơn” place the mountain here: a 1+ km ridge of Chùa, Hà Mã, and Kho peaks south of Cổ Mễ village.
(b) Quế Võ district — specialized studies (Lê Mạnh Thát in Thiền uyển tập anh annotations; Bách Việt trùng cửu fieldwork; the Đại Nam Nhất Thống Chí itself, when cross-referenced against Nguyễn-era administrative boundaries) place the core site in the former Quế Dương and Võ Giàng districts, today’s Quế Võ: Châu Phong commune (villages Châu Cầu, Thất Gian) and Ngọc Xá commune (villages Hữu Bằng, Cựu Tự, Kim Sơn, Long Khê). The gazetteer specifies “12 dặm east of Quế Dương district.”
Likely resolution: “Trâu Sơn” names the entire ridge. The core archaeological and cultic site — Việt Tỉnh, the Việt King’s tomb, the Yin King’s temple — lies in Quế Võ. Vũ Ninh ward (Bắc Ninh city) occupies a northwestern spur of the same ridge.
Việt Tỉnh cương
Lê Mạnh Thát explains: “Tỉnh cương is a mound on Trâu mountain. The mound is called ‘Well Mound’ because it contains a well. Beside it was probably a pond, and because it sits near the Việt King’s tomb, it was called Việt Vương trì (Việt King’s Pond).”
Vũ Vĩnh Trinh’s poem (Nguyễn dynasty): “越井荒涼幾度秋 / 鄒山遺跡至今留” — “The Vietnamese Well, desolate through how many autumns / Trâu Sơn’s vestiges endure to this day.” Evidence that Việt Tỉnh cương was still a recognizable place-name into the 19th century.
Folk religion — associated cults
Triệu Vũ Đế worship at Quế Võ
The Bắc Ninh Museum records some ten villages worshiping Triệu Đà as village guardian spirit, concentrated in Quế Võ and Từ Sơn. Six villages around Trâu Sơn — Châu Cầu, Thất Gian, Hữu Bằng, Cựu Tự, Kim Sơn, Long Khê — formerly enshrined Triệu Vũ Đế and his consort Lady Trình as principal guardian deities. The Museum preserves copies of village spirit registers filed with EFEO in 1938. Hữu Bằng pagoda (Ngọc Xá) retains a damaged wooden statue of Triệu Vũ Đế. Cựu Tự village has a stone Phi Liêm — a Qin-Han era zoomorphic sculpture.
Cô Tiên temple — the Ma Cô cult
The Đại Nam Nhất Thống Chí notes: “Beside the mountain is the Ma Cô Tiên temple.” The Cô Tiên temple (Châu Cầu village, Châu Phong commune, Quế Võ) still stands. However, surviving investiture decrees (nine documents, earliest Cảnh Hưng 44 = 1783) address not Triệu Vũ Đế but “Celestial Immortal Holy Mother, First Cửu Trùng Princess” — evidence of a Mother Goddess (Đạo Mẫu) cult overlay upon the older Yin King – Ma Cô stratum.
No “Giếng Việt festival”
No festival explicitly named after the tale has been recorded in Bắc Ninh gazetteers or in Địa chí Hà Bắc. The living cult forms are the Triệu Vũ Đế worship at six villages and the Ma Cô veneration at the Cô Tiên temple.
Historical characters — cross-referencing the sources
Thôi Lượng and Thôi Vỹ — purely literary figures
Neither appears in Shiji, Hanshu, Đại Việt Sử Ký Toàn Thư, Việt Sử Lược, or Khâm Định Việt Sử Thông Giám Cương Mục. “Grand Censor of the Qin” is a real office in the Qin–Han bureaucracy, but the individuals have no historical attestation.
Nhâm Ngao (任囂) — attested historical figure
Đại Việt Sử Ký Toàn Thư, Ngoại kỷ vol. I, folios 8a–9b: “Nhâm Ngao was made Commandant of Nanhai, Triệu Đà Magistrate of Long Xuyên… they brought 500,000 convicted soldier-laborers to garrison the Five Passes… Ngao brought a naval force to Tiểu Giang… having offended the local earth spirit he fell ill and had to withdraw.” Comparison: ĐVSKTT neutralizes (“offended the earth spirit”); LNCQ mythologizes (“struck dead by the god Xương Cuồng”).
Ma Cô (麻姑 / Magu) — Daoist immortal
Earliest literary source: Ge Hong’s Shenxian zhuan (4th c. CE). Robert Campany (To Live as Long as Heaven and Earth, UC Press 2002, pp. 259–270) confirms this as the earliest depiction. Magu symbolizes longevity and is associated with the phrase “seas become mulberry fields.” In LNCQ she is localized as the Yin King’s emissary, functioning as matchmaker and jade-bestower — a thorough Vietnamese domestication of a Chinese Daoist figure.
Textual history — transmission and variants
Position within the 22-tale canon
Tale 12 (volume 2), between Lý Ông Trọng truyện (11) and Kim Quy truyện (13). A pivot point: bridging the Hùng Vương era and the Triệu era, between the “heroic transition” cluster and the “state-founding / romance” cluster.
15 surviving manuscripts
Per Nguyễn Thị Oanh’s doctoral dissertation (ĐHSP Hà Nội, defended 22/10/2005, catalogued at the National Library as LA05.0374.3): 15 manuscripts — 12 at the Institute of Hán Nôm Studies, 2 at the National Library, 1 at the Institute of History. Two key base texts: A.2914 (Institute of Hán Nôm) — used by Nguyễn Thị Oanh (2024); HV.486 (Institute of History) — used by the Việt Nam Hán Văn Tiểu Thuyết Tùng San (Taipei 1992).
Notable variants
- Character names: “Thôi Lượng” (崔量) vs. “Thôi Lạng” (崔亮) — near-homograph confusion. “Nhâm Ngao” (LNCQ, Nguyễn Hữu Vinh ed.) vs. “Nhâm Hiêu” (ĐVSKTT romanization).
- Nhâm Phu: explicit in the Nguyễn Hữu Vinh edition; absent or vague in some other versions.
- Date of Nhâm Ngao’s death: “3rd of the 1st month” (Nguyễn Hữu Vinh) vs. “13th of the 1st month” (Bách Việt trùng cửu citation).
- Serpent’s name: “Ngọc Kinh Tử Xà” (standard) vs. “Vương Kinh Tử” (Bách Việt trùng cửu citation).
Motifs and symbolism — analysis
Well/cave to otherworld
Vỹ falls into the well → reaches an alternate world (the Yin Queen’s palace) → is returned. This is the “entering a cavern and meeting immortals” motif, widespread in East Asian zhiguai and chuanqi. Đoàn Vĩnh Phúc (postface, early Quang Bảo era, 1554) acknowledged that LNCQ tales “resemble the stories of Pei Hang and Bieyi from the Song.” Nguyễn Huệ Chi and Nguyễn Đăng Na classify this as a transitional step from zhiguai to chuanqi — prefiguring Từ Thức tiên hôn lục and Phạm Tử Hư du thiên tào lục in Nguyễn Dữ’s Truyền kỳ mạn lục.
Ngọc Kinh Tử Xà — the serpent as Việt sacred creature
White divine serpent with golden crest, inscribed forehead, body a hundred fathoms — an underworld sovereignty emblem. The Ming-era An Nam Chí independently records a “Stone Serpent called Ngọc Kinh Tử” on Vũ Ninh mountain. This is one of the rarest serpent-as-sacred-creature appearances in Vietnamese Hán-Nôm literature, alongside the Linh Lang serpent and the Dạ Trạch serpent.
Long Tụy jade — royal qi migrates south
Paired male-female gems transmitted from the Yellow Emperor → Yin dynasty → buried at Trâu Sơn, yet radiance pierces the sky → “people read the spirit-energy and know the jade remains in the southern land.” Symbol: dynastic legitimacy has migrated from the Central Plains to Vietnamese soil.
Xương Cuồng — cross-tale linkage
Appears in both Truyện Mộc tinh (tale 4) and Truyện Giếng Việt (tale 12). In tale 4: the chiên đàn tree at Bạch Hạc becomes a demon, demanding human sacrifice on the 30th of the 12th month each year. In tale 12: kills Nhâm Ngao. Đặng Tiến identifies Xương Cuồng as the Tiger God (“Cọp, từ Mộc tinh đến ông Ba Mươi”, diendan.org, 2010). The two tales are editorially interwoven — sharing a single indigenous divine figure who punishes northern interlopers.
Stone goat transformation
Lord Dương (羊 = goat/sheep) petrifies into a stone goat behind the Việt Vương temple. This rationalizes an actual archaeological artifact — a stone animal sculpture of Qin-Han provenance — at the Hữu Bằng – Cựu Tự temple complex. Stone goat veneration is rare in Vietnam; the sculpture likely originates as a funerary or geomantic object that was mythologized by later generations.
Embedded verse
Thôi Lượng’s inscription poem — regulated seven-syllable octave counterposing “Việt Thường” / “Ân đức” and “Uy Linh” / “quốc tộ” — is among the earliest embedded poems in Vietnamese narrative prose. Nguyễn Đăng Na cites this as evidence the tale “already contains a clear authorial dimension,” distinguishing it from purely mythological tales.

Modern scholarship
Đinh Gia Khánh – Nguyễn Ngọc San (NXB Văn hóa, 1960, 137 pp.): standard Vietnamese translation. Đinh Gia Khánh stressed LNCQ as a high-value indigenous folklore collection, while acknowledging foreign influence in certain tales.
Nguyễn Huệ Chi (Từ điển Văn học Bộ mới, NXB Thế giới, 2004): emphasized LNCQ’s “marvelous-strange” (kì ảo) mode as the bridge to the truyền kỳ genre of Nguyễn Dữ. Noted that Truyện Giếng Việt “was influenced by Chinese tales” (cited on Vietnamese Wikipedia, LNCQ entry).
Nguyễn Đăng Na (textbooks on medieval Vietnamese narrative, NXB Giáo dục): classified LNCQ as “mostly legend-type tales… not yet separated from folk literature, yet inaugurating medieval narrative prose from folk-narrative origins.” Within this framework, Truyện Giếng Việt belongs to the class of tales “already possessing a clear authorial dimension.”
Nguyễn Thị Oanh (NXB KHXH, 2024, 720 pp.; National Book Award Grade B, 8th cycle): most comprehensive monograph to date. Appendix II provides full annotated translation of Việt Tỉnh truyện from manuscript A.2914. Also compares LNCQ with the Japanese Nihon ryōiki (日本霊異記) — East Asian textual parallelism.
Trần Đình Hoành (dotchuoinon.com, 2010–2015): most detailed ethical-philosophical commentary. Reads the tale through Buddhist-Confucian lenses: virtue transforms, grace repays across generations, the goat-chariot echoes the Lotus Sūtra Parable of the Burning House.
Bách Việt trùng cửu (bahviet18.com, 2013–2019): most detailed fieldwork on the Trâu Sơn – Quế Võ temple complex. Valuable findings (investiture decrees, Triệu Vũ Đế statue, Phi Liêm sculpture), but unconventional historical interpretations (equating Triệu Đà with Lưu Bang). Use for fieldwork data; exercise caution with theoretical framework.
Living legacy
Truyện Giếng Việt has no dedicated festival, no stamp series, and little presence in general education. Its legacy survives in three forms:
(1) Place-names. Việt Tỉnh cương is the deepest-rooted toponym explaining a real cluster of sites in Quế Võ, Bắc Ninh. The name “Giếng Việt” persists in Vũ Vĩnh Trinh’s poem, in the Đại Nam Nhất Thống Chí, and in the spirit registers of six villages.
(2) Yin King – Triệu Vũ Đế worship. The tale is the narrative charter explaining the origin of the Yin King cult at Trâu Sơn — a cult attested at least since LNCQ’s composition (14th–15th c.) and possibly much earlier.
(3) Literary-historical milestone. With its three narrative layers, embedded verse, and purposeful fantastic plot, Truyện Giếng Việt is living evidence of the transition from zhiguai to chuanqi in medieval Vietnamese prose. Nguyễn Huệ Chi and Nguyễn Đăng Na both invoke LNCQ — and particularly tales like Giếng Việt and Hà Ô Lôi — to substantiate this thesis.
Usage caveats
-
Thi viện misattribution: Thi viện credits LNCQ to Nguyễn Dữ. This is incorrect. The original compiler is Trần Thế Pháp; Vũ Quỳnh and Kiều Phú edited. Nguyễn Dữ authored Truyền kỳ mạn lục (16th c.).
-
“Nhâm Ngao” vs “Nhâm Hiêu”: same person (任囂). “Nhâm Ngao” is the LNCQ romanization; “Nhâm Hiêu” is the ĐVSKTT romanization. Both are used in scholarship; choose one and note the other.
-
Bách Việt trùng cửu source: strong fieldwork data, unconventional theoretical framework. Use with care.
