TL;DR: This article explains the common Vietnamese custom of the ground-breaking ceremony for building a house: choosing a date compatible with the householder's age, preparing offerings (chicken, sticky rice, incense, fruit), arranging the altar, reciting the prayer text, burning joss paper, and then the householder making the first digs before workers excavate the foundation. It also mentions the roof-raising ceremony (thượng lương) and distinguishes these from the village's spring ground-breaking rite. This is a reference custom that may vary by region and family; the ceremony is not a substitute for proper technical design and construction.
How to Conduct the Groundbreaking Ceremony for Building a House Correctly
What is the groundbreaking ceremony for building a house?
Động thổ (groundbreaking, or commencement of construction) is an important ritual in the life cycle of every Vietnamese family, marking the moment construction of a new home begins. People in the past believed that asking permission from the thổ công (land deity) and the spirits who govern the land would help the project go smoothly and keep the household at peace. However, this is a widespread custom meant for reference, not a mandatory rule; each region and each family may have its own variations. This article gathers the most common way of conducting the ceremony, and you should combine it with local tradition and the advice of experienced people.
The steps of the groundbreaking ceremony for building a house, in the order given in this article.
| Step | Main action | Items | Timing |
|---|---|---|---|
| 1 | Recite the prayer text | Incense | In front of the offering tray |
| 2 | Burn votive paper and scatter rice and salt | Votive paper, rice, salt | When the incense has burned about two thirds, roughly 15 to 20 minutes |
| 3 | Groundbreaking | Shovel, hoe or hammer | At the spot where the foundation is planned |
| 4 | Finish and tidy up | After the incense has burned out |
What needs to be prepared before the groundbreaking ceremony?
How should an auspicious date and time for the groundbreaking ceremony be chosen?
In folk belief, one should choose a good day and a good month, avoiding days that clash with the age of the head of the household. You can ask a feng shui master or someone well versed in the lunar calendar, or look it up yourself in a perpetual calendar to choose an Hoàng đạo (auspicious) day and hour that does not fall under major inauspicious stars, trùng tang (unlucky repetition of mourning days) and so on. Choosing the date and time is only for reference, and you should not worry too much if a perfect day cannot be found.
What does the groundbreaking offering include?
The groundbreaking offering tray usually includes:
- A five-fruit tray (seasonal, five different kinds of fruit may be used)
- Fresh flowers (usually chrysanthemums, roses, gladioli)
- Betel and areca (3 betel leaves, 3 areca nuts, or 1 pair of betel and areca)
- Plain rice wine, beer, bottled water (1 bottle or 1 glass of each)
- Rice and salt (a small bowl of each)
- Votive paper money (including paper money, paper clothes, paper hats and so on)
- One boiled rooster (or roast pork, bánh chưng, depending on circumstances)
- Sweets and cigarettes (if the head of the household smokes)
- Sweet soup and cigarettes (can be added if desired)
- A tam sinh set (if the family holds a large ceremony, pork, eggs, shrimp and so on may be used)
- A shovel, hoe or hammer (the tool for the head of the household to break ground)
How should the groundbreaking offering tray be arranged?
The offering tray is set out in a clean place, usually facing the front of the house or where the foundation will be laid. Arrange the offerings on a table or mat in this order:
- Incense, flowers and lamps (candles) on the outer side, near the person praying.
- The five-fruit tray, betel and areca, rice and salt, and votive paper on the inner side.
- Wine, beer and water in front of the tray.
- The boiled chicken or savory offerings in the central position.
Note: if you burn votive paper, incense or candles, place them in an open area, away from flammable objects, and always have someone watching over them.
How is the groundbreaking ceremony carried out?
Step 1: Recite the prayer text
The head of the household (or a representative) lights incense, stands before the offering tray and reverently recites the prayer text. The content of the prayer usually covers the main points: respectfully informing the various deities, the thổ công and the spirits who govern the land; stating clearly the full name of the head of the household, the address, and the date and time of the groundbreaking; expressing sincerity and asking permission to begin construction; and praying for protection so that the project goes smoothly and the family stays well. You can find common prayer texts in books or on reputable websites, or compose your own words of prayer: sincerity is what matters. After reciting, bow three times.
Step 2: Burn votive paper and scatter rice and salt
After the prayer is finished (about 15 to 20 minutes, when the incense has burned about two thirds), the head of the household takes the votive paper to a safe place to burn it, away from houses and dry trees. Before burning, a little rice and salt can be scattered around the plot of land, meaning to drive away evil influences and wish for good fortune. Scattering rice and salt is not obligatory and depends on local custom.
Step 3: Groundbreaking (the first shovel of earth)
The head of the household holds a shovel, hoe or hammer and personally digs or strikes a few times into the ground at the spot where the foundation is planned. This action symbolizes the official start of construction. If you cannot do it yourself, you can ask someone whose age is compatible with the head of the household to do it instead. After that, the workers can begin construction.
Step 4: Finish and tidy up
After the groundbreaking, the head of the household waits for the incense to burn out, then tidies up the offerings. Offerings such as fruit, cakes and sweets can be given away or shared with children, and should not be thrown away. Once the votive paper has finished burning, the ashes should be collected and cleaned up.
What important notes are there for the groundbreaking ceremony?
- Fire and explosion safety: When burning votive paper, lighting incense or candles, place them far from flammable materials, have someone watch over them, and prepare water or a fire extinguisher. Do not burn too much votive paper at once.
- Respect for the surroundings: Do not litter and do not make noise that disturbs the neighbors.
- Adapt to the region: People in the north usually offer a boiled rooster, while people in the south may use roast pork or bánh tét. Some places also offer sticky rice and sweet soup. Ask relatives and neighbors to get it right.
- Do not be excessively superstitious: The offering ceremony is spiritual in nature and cannot absolutely guarantee good luck or safety. The most important thing is technically sound building design and compliance with the law.
Is the roof-raising ceremony (thượng lương) part of building a house?
Yes. Cất nóc (roof raising) is the ceremony of placing the main ridge beam at the top of the house, held after the frame has been erected and before moving into the new home. Song Mai and Quỳnh Trang tuyển soạn (2006) record that the homeowner asked someone to look at the date and choose the hour so that the building work would be lucky and peaceful; at the chosen date and time, the main ridge beam of the roof was placed on top of the roof frame.
According to Song Mai and Quỳnh Trang tuyển soạn (2006), a piece of red cloth was attached to the ridge beam, inscribed with the date of the ceremony and the words "Khương Thái công tại thử" (Jiang Taigong is here). Some families used a bagua talisman instead of that red cloth. At the same time, a ceremony was held to report to the ancestors; when it was over, firecrackers were set off. The use of the red cloth, the words of Khương Thái công or the bagua talisman is a folk notion meant to ward off evil spirits, and the sound of firecrackers both expressed joy and was meant to drive away evil spirits, rather than being anything verified.
How does a village's spring groundbreaking ceremony differ from the groundbreaking ceremony for building a house?
These are two different ceremonies. The groundbreaking ceremony for building a house is performed by the head of the household on their own plot of land; the spring groundbreaking ceremony is a ceremony of the whole village, opening the year's first breaking of the soil.
According to Toan Ánh (2001), in the spring groundbreaking ceremony the chief officiant, wearing a blue robe, hoed a few strokes, then took a clod of earth and placed it on the altar to present it to the Thổ thần (earth deity). Only after the ceremony were the villagers allowed to touch the soil. Also according to Toan Ánh (2001), any household in mourning during the three days of Tết had to keep the body laid out and wait until the ceremony was over before digging the grave.
Why must a date compatible with the homeowner's age be chosen before breaking ground?
Because, according to the recorded custom, building a house is regarded as a major undertaking, so people chose a date compatible with the homeowner's age and only then held the groundbreaking ceremony. In Tục thờ cúng của người Việt (2001), Bùi Xuân Mỹ writes: "after choosing a date compatible with the homeowner's age, people hold the groundbreaking ceremony (worshipping the earth deity) to ask permission to build a house on that plot of land". In other words, according to the author, the step of choosing a date by age came first, and then came the offering to the earth deity to ask permission to build on that plot. This is how folk custom understands it, not a rule binding on every family.
Also in Tục thờ cúng của người Việt (2001), Bùi Xuân Mỹ notes that the groundbreaking ceremony in earlier times required a tam sinh offering; today the ritual has become simpler, though chicken, sticky rice, incense and fruit are still indispensable. After the ceremony, the homeowner themself took a hoe and struck the first blows, regarded as presenting to the Thổ thần the request to break ground; only after that were the workers allowed to dig the foundation. This description matches the sequence of steps above, differing only in emphasizing that the homeowner hoes first before the workers dig the foundation.
Should one believe that skipping the groundbreaking ceremony brings bad luck?
One should not assert that. The books that record this custom only reflect that people in the past held the ritual in high regard, because they believed building work was bound up with the lives of those who would later live in the house; as for what consequences skipping the ceremony might bring, those books give no guarantee at all. You can regard the offering ceremony as a customary practice that sets the mind at ease, while the safety of the project depends on design, construction and compliance with building regulations.
