Turning off the main road into the village of Cao Xá Thượng, you pass along village lanes before reaching the three-entrance gateway (tam quan), and beyond it an inner gateway with a loft where a chime (khánh) hangs. Past the gate lies a cluster of low tiled roofs, ridges modeled with dragons and a frame of ironwood (lim) columns darkened with age. In the innermost hall, beneath the altar of the rear sanctuary, there is a well, which the sources call the Ngọc well, the Jade Well.
The place is called Linh Tiên quán, and people in the area know it as chùa Linh Tiên, Linh Tiên Pagoda. It does not belong to the set of four Taoist temples of the old capital. It is a village Taoist temple, known in books and the press as a temple for refining the elixir. On its altars are the Jade Emperor, the Three Pure Ones and Laozi, and beside them the Buddhist Quán Âm (Guanyin) and Confucius. This page tells the legendary layer and the historical layer of the temple, and keeps them apart.

IThe Jade Emperor, the Three Pure Ones and the Three Teachings
According to the Đồng Nai Library, the temple honors the Jade Emperor, the Three Pure Ones and Laozi, the highest figures of the Taoist pantheon, with statues of Confucius and Quán Âm beside them. Dân Việt and Giáo dục và Thời đại also describe a main hall with a set of statues of the Three Pure Ones together with Buddhist and Confucian figures. It is a typical place of worship of the Three Teachings sharing one source (Tam giáo đồng nguyên), very familiar in the villages of northern Vietnam.
Linh Tiên is not one of the four Taoist temples of Thăng Long, the set of four quán of the old capital introduced on the page on Huyền Thiên Temple. It is the temple of a village outside the city, and precisely because it is in a village it has kept more objects than the temples in the city streets.
The Three Pure Ones are the three highest deities of Taoism, Yuanshi Tianzun, Lingbao Tianzun and Daode Tianzun. The third is identified with Laozi, whom Taoism honors as its founder. The Jade Emperor is the king of heaven, who governs the realms. A temple that honors both the Three Pure Ones and the Jade Emperor honors the whole top tier of the Taoist pantheon, unlike temples devoted to a single deity with a particular charge, such as Huyền Thiên Trấn Vũ.
The word alchemy attached to the temple belongs to another branch of Taoism, the art of refining an elixir of long life, known in the past as external alchemy, which used a furnace and water to refine the elixir. Later Taoism moved gradually toward internal alchemy, the refining of qi within the body. The name temple for refining the elixir that the press gives to Linh Tiên refers to this legendary layer of external alchemy.
Three points are often misread. First, Linh Tiên is not one of the four Taoist temples of Thăng Long, even though it is also a Taoist temple in Hanoi. One article online calls it Đan Sơn tứ quán nhất, the first of the four temples of the Đan Sơn area, but the library has not been able to check this against any official source, so it is given only as a name in use, not as a fact.
Second, the common name chùa Linh Tiên does not mean the temple has become a wholly Buddhist pagoda. The statues of the Three Pure Ones and the Jade Emperor are still in the main hall. Third, the idea that Lü Jia practiced here and that the Ngọc well was his alchemical furnace both belong to legend, not to the historical record. The section below keeps those two layers clearly apart.
IILü Jia in legend, the Mạc dynasty in the record
The history of Linh Tiên quán has two layers nearly two thousand years apart, and they need to be read separately.
The legendary layer. According to local people, as recorded by Giáo dục và Thời đại, the temple dates from around 111 BCE and is tied to Lü Jia (Lữ Gia), chancellor of the kingdom of Nanyue, who is said to have come to this area to practice. In the temple hangs a wooden board in Chinese characters, explained as a copy of an earlier stone stele. It tells that in the time of the Triệu dynasty Lü Jia came to this village, saw immortals playing chess and knelt to bow to them, the immortals rose into the sky, and on that account Lü Jia founded Linh Tiên quán. The Đồng Nai Library and Dân Việt both record that the Ngọc well beneath the rear sanctuary is said to have been Lü Jia's alchemical furnace. The date of 111 BCE is a year within the legend, not the year the temple was built, and there is no way to verify it.
The historical layer. What stands today shows that the temple was rebuilt in the Mạc period. Three sources give three different years. The Đồng Nai Library and Dân Việt give 1544, with Princess Mạc Kim Dung and her husband as sponsors. Giáo dục và Thời đại also records the Giáp Thìn year 1544 with the prince consort Mạc Ngọc Liễn and Princess Mạc Kim Dung, and at the same time quotes the researcher Minh Nhương as saying the temple was restored under the Mạc dynasty in 1584, while Chốn Thiêng gives a stele carved in 1586. These may be three stages of one long building campaign, or they may be discrepancies between the sources. The library has not seen the full text of the stele and does not settle the question.
Dân trí and Giáo dục và Thời đại also record a major restoration under King Trần Minh Tông, after the king's daughter, Princess Thái Trưởng, came to the temple to pray for a child, and the villagers made a statue of the king to worship in the front hall. No stele recording this has been found, so the library notes it and does not include it among the main dates.
- Around 111 BCEA date within the legendAccording to local people, the temple dates from this time and is tied to Lü Jia. This is legend, not a building date.
- 1544Major rebuildingAccording to the Đồng Nai Library, Dân Việt and Giáo dục và Thời đại, Princess Mạc Kim Dung and her husband sponsored the rebuilding. Dân Việt records that this rebuilding enlarged the grounds and changed the temple's facing.
- 1584 to 1586Mạc-period architecture and steleGiáo dục và Thời đại quotes the researcher Minh Nhương as saying the temple was restored under the Mạc dynasty in 1584. Chốn Thiêng gives a stele carved in 1586.
- 17th and 18th centuriesCarved workGiáo dục và Thời đại records that the temple's dragon-carved palanquin dates from these two centuries, while most of the decoration bears the marks of art from the Revival Lê period to the Nguyễn period.
- 1797The bronze bell is castThe great bell now hangs in the bell loft behind the upper hall. Dân Việt and Giáo dục và Thời đại record that it is about 1.4 meters tall and was cast in the Tây Sơn period, in the Cảnh Thịnh reign.
- 1990National rankingRanked as a national historical and cultural heritage site by Decision No. 34VH/QĐ of 9 January 1990, according to Giáo dục và Thời đại.
IIIIronwood frame, the Ngọc well and the store of printing blocks
Dân trí describes the whole frame of the temple as ironwood (lim), with curved upturned eaves and dragons carved on the roof ridge, and notes that in several hundred years no sign of termites has been seen. Giáo dục và Thời đại records that most of the decoration bears the marks of art from the Revival Lê period to the Nguyễn period, such as a pair of blue stone nghê (guardian beasts), an incense table, a pair of wooden cranes, a carved window panel, and a dragon-carved palanquin made in the 17th and 18th centuries. This is the village architecture of the northern delta, not the look of a Chinese Taoist temple, and it shows that the villagers built their quán in exactly the way they built their communal houses and pagodas.
Directly beneath the innermost altar. Said to have been Lü Jia's alchemical furnace. Giáo dục và Thời đại records that the well is more than ten meters deep with a hidden chamber inside, and villagers say it connects to the Red River. That is what people tell, not the result of a survey.
The statues of the Three Pure Ones, the Jade Emperor and Laozi hold the central places, with Quán Âm and Confucius beside them. This is where the Taoist character of the place is clearest.
Dân trí records that the temple has more than five hundred objects, antiques and reproductions together, among them several dozen woodblocks carved with Buddhist and Taoist scriptures. Only one block remains at the temple today, and the rest are kept by the National Museum of Vietnamese History and the Hanoi Museum.
Hung in the bell loft behind the upper hall, with the Mạc-period stele Tu tạo bi ký (Record of Restoration) standing on a stone turtle below. The temple follows a chime in front, bell behind arrangement, with the chime in the loft of the inner gateway at the front and the bell at the back.
The most striking detail is still the well inside the hall. Very few places of worship in northern Vietnam put a well beneath the very altar of the rear sanctuary. A village well is usually in a courtyard or in front of the communal house, not in the most sacred spot. Placing water at the heart of the hall at Linh Tiên fits the alchemy legend, since alchemy needs clean water, and it also shows that the builders saw the water source as something to be kept hidden and to be worshipped.
The store of printing blocks also says something about the temple's role. A place that kept blocks for printing both Buddhist and Taoist scriptures probably once printed books for people in the area, which means it had a life of study, not only of offerings. The Chinese characters at the top of this page are written by the library after the name Linh Tiên quán and have not been checked against the horizontal boards on site.
IVThe lie of the land and the facing
Everything below is the library's own reading in the manner of traditional feng shui. Only the change of facing in 1544 is a fact, recorded by Dân Việt, and the explanation of why it was made is the library's own.
The temple stands in the middle of the village plain west of Hanoi, with no mountain to lean on. In such places, the traditional reading of land does not look for the dragon vein (long mạch) on the surface but for the water vein under the ground, because groundwater is the only thing that connects a flat piece of land with the qi of the whole region. The Ngọc well, more than ten meters deep and believed by villagers to connect to the great river, is in this reading the node (huyệt) of the temple. To set the altar directly over the node is to set the place of worship exactly where the qi gathers, and this explains why the well lies inside the hall rather than out in the courtyard.
The second point is the change of facing. Dân Việt records that the rebuilding of 1544 turned the temple from facing southwest to facing northeast. In the old way of seeing, southwest and northeast are an opposed pair on the same axis. To face northeast is to turn the back to the southwest and open the front toward the old capital and the Red River. The library does not know why the people of the Mạc period changed the facing, whether for feng shui or because of the village roads, so it gives only the fact and one way of reading it.
Lastly, a place for refining the elixir in legend needs three things, clean water, quiet ground and distance from crowds. The village of Cao Xá Thượng has all three, and that is perhaps why the legend found its way here rather than anywhere else.
VThe Jade Emperor's day and the village festival
Chốn Thiêng records that the temple holds a major rite on the 9th day of the 1st lunar month and that the village festival of Cao Xá Thượng falls on the 13th day of the 2nd lunar month, besides the rites on the first and fifteenth days of each lunar month. The 9th day of the 1st lunar month is the Jade Emperor's day in the Taoist ritual calendar, matching the deity worshipped in the main hall.
| Lunar date | Rite | Meaning |
|---|---|---|
| 9th day of the 1st lunar month | The temple's major rite | Falls on the Jade Emperor's day in the Taoist ritual calendar, the temple's rite at the start of the year |
| 13th day of the 2nd lunar month | Cao Xá Thượng village festival | A festival of the whole village, held by the village festival calendar rather than the Taoist one |
| 1st and 15th days | Regular monthly rites | Villagers come to the temple to offer incense by custom |
The way the ritual calendar falls into two tiers also shows the temple's two roles. The 9th day of the 1st month is a rite of the faith, by the Taoist calendar, turned toward the king of heaven. The 13th day of the 2nd month is a rite of the village, by the village festival calendar, turned toward the community. A village Taoist temple has lived through many centuries precisely by keeping both tiers.

The temple is a place of worship belonging to the village, and its customs are the village's. Visitors are expected to dress modestly, remove hats on entering the halls and speak quietly. The Ngọc well lies directly beneath the altar of the rear sanctuary, and visitors are asked not to lean over its mouth, not to drop anything into it and not to draw water. The printing blocks and wooden statues are antiques, to be looked at, not touched.
