Folk Taboos for Groundbreaking, House Construction, and Housewarming

What are the folk taboos for ground-breaking, house-building and house-warming?

In Vietnamese culture, a house is not only a shelter but also a home, a place where vital energy gathers and where people connect with their ancestors and with the land. For this reason, the rituals from ground-breaking and construction to house-warming are all treated with respect, and they come with a rich system of folk taboos. This article looks in depth at the common beliefs and practices, helping you understand their cultural meaning and apply them sensibly.

What is the meaning of ground-breaking, house-building and house-warming?

Ground-breaking is the ritual of asking permission from the deities and the local earth spirit for the plot of land that is to be dug up and built on. People in the past believed that every stretch of land has a deity in charge of it, and that digging without permission would bring misfortune. Building a house is the process of creating a living space, and it needs to be in harmony with feng shui so as to bring health and prosperity to the householder. House-warming, also called the ceremony of entering a new home, marks the moment of officially moving to a new place; it is when the deities and ancestors are invited to take up residence there, and so it too has its own set of rules.

What are the taboos about choosing days and hours?

Choosing an auspicious day and month is the first important step. Vietnamese people usually avoid bad days such as Tam Nương days (the 5th, 14th and 23rd of the lunar month), Nguyệt Kỵ days (the 5th, 14th and 23rd), Sát Chủ days, Thập Bại days, or days that clash with the householder's age according to the sixty-year cycle. Conversely, one should choose a Hoàng Đạo day, a day with auspicious stars such as the Thiên Hỷ star or the Nguyệt Đức star, or one of the major festivals of the year. The hour of ground-breaking should also avoid bad hours such as the Tý hour (11pm to 1am), when yin energy is strong, or the Mùi hour (1pm to 3pm) in folk belief. The choosing of dates is usually entrusted to a feng shui master or someone well versed in the lunar calendar, but you can also look it up yourself based on the principle of picking a day whose heavenly stem and earthly branch do not clash with your age.

What are the taboos about the orientation and position of a house?

The orientation of a house is seen as the factor that decides its fortune. People avoid building a house in an orientation that clashes with the householder's destiny, for example someone with a Kim destiny should not build a house facing South (fire overcomes metal). In addition, one should avoid bad configurations such as a house directly facing a three-way or four-way junction, a house that a main road runs straight into (the "knife edge" configuration), or a house blocked at the front door by an electricity pole or a large tree. When digging the foundations, people avoid striking strange objects such as graves, the roots of old trees, or unusually large rocks, because these are believed to be the dwelling places of deities or spirits. If such a thing is found, a ceremony must be held to ask permission to move it before work continues.

What are the required rituals and the objects to be avoided?

The ground-breaking ceremony: Before digging the foundations, the householder prepares a tray of offerings that includes a boiled cockerel, glutinous rice, wine, betel and areca, votive paper, incense and flowers. The offerings are placed at the corner of the plot where the house is to be built, and the householder (the principal male) lights incense and asks the local earth spirit for permission, then strikes the ground three times with a hoe in an auspicious direction. The person who performs the ground-breaking should not be someone in mourning, a pregnant woman, or someone who has just recovered from illness, since such people are considered to carry yin energy or to be vulnerable to spiritual forces.

During construction: Avoid letting strangers, people in mourning, or pregnant women onto the site on important days such as pouring the roof, placing the beam, or raising the roof ridge. In particular, when pouring the concrete roof, people avoid letting a pregnant woman come near, for fear of affecting the unborn child and the durability of the work. Materials such as bricks, stones and steel must not be thrown about carelessly, and blood or dirty substances must absolutely be kept away from the foundations. It is also taboo to let a mirror break or a knife or scissors fall onto the foundations, because these can create hostile energy.

The house-warming ceremony: Once the house is finished, before moving the furniture in, the householder must hold the house-warming ceremony. The offering tray usually includes the three sacrificial offerings (pork, chicken, eggs or shrimp), glutinous rice, sweet soup, wine, fruit and votive paper. The householder lights incense and asks the deities, the local earth spirit and the ancestors to come and reside in the new place. The taboos of house-warming include:

• Do not enter an empty house: You must bring in some essential items such as a fire, a rice pot, rice, salt, water and a new broom. This symbolises abundance and the sweeping away of bad energy. Entering an empty house with nothing brings bad luck.
• The first visitor: The first person to step into the new house matters greatly. You should choose someone whose age is compatible, who is cheerful and successful, to be the first visitor and bring good luck. Avoid people whose age clashes, people in mourning, or people who have just been quarrelling.
• Do not sweep the house right after entering: After the house-warming ceremony, sweeping is avoided for the first three days for fear of sweeping prosperity away. If tidying is needed, only sweep from the outside inwards and gather the rubbish together without throwing it out.
• Avoid borrowing or repaying debt on the first day: Borrowing money or repaying debt on the day of house-warming is considered a bad omen, signalling scarcity in the future.
• Do not move in broken old belongings: Old or broken furniture, or items carrying bad energy such as broken mirrors or photographs of the deceased (except the ancestral altar), should not be brought into the new house.

What are the beliefs about age and destiny when building a house?

The householder's age plays an important role. People avoid building a house in a year when their age falls under Kim Lâu (even-numbered ages such as 26, 28, 30, 32 and so on), Hoang Ốc (ages such as 12, 14, 15, 18, 21, 23, 27, 29, 30, 32, 34, 36, 39, 42, 44, 45, 47, 49, 51, 53, 54, 56, 60 and so on), or Tam Tai (ages that meet the tam tai misfortune according to the three-combination groups). If it cannot be postponed, one may borrow another person's age, usually someone older who has good fortune and does not fall under the above misfortunes, to stand in and perform the ground-breaking and house-warming ceremonies. However, borrowing an age requires the consent of the person whose age is borrowed and must be carried out with the proper ritual.

What are the other taboos during construction?

• Avoid building a house in the 7th lunar month (the month of wandering souls), because people believe that wandering spirits easily disturb the work.
• Do not build a house on rainy, stormy or thundery days, because construction is difficult and accidents are likely, and it also symbolises instability.
• For pouring the roof and raising the roof ridge: Avoid letting pregnant women or people in mourning witness it. People believe that if this happens, the house will easily run into problems or the householder will meet with misfortune.
• When digging a well or a pond: Avoid digging in the Southeast (the direction of the God of Wealth), because it may affect prosperity.
• Avoid building a toilet in the centre of the house, because this is the main energy zone and easily defiles the deities.
• Do not use wood that has been struck by lightning or infested with termites, or wood from old trees struck by lightning, because it carries bad energy.

How can these be resolved, and what are the exceptions?

If one has accidentally broken these taboos, people usually look for ways to resolve them, such as:

• Holding a ceremony to apologise to the deities and the local earth spirit, then drawing a fortune stick or asking a feng shui master how to resolve it.
• Hanging a bagua mirror, or feng shui items such as a pixiu, a three-legged toad, or a string of five-emperor coins, to guard against bad directions.
• If one's age falls under Kim Lâu or Hoang Ốc, one may borrow another person's age, or wait until the following year.
• If the house-warming falls on a bad day, one may hold a thank-offering ceremony and ask to change the date, or perform a simpler ritual and then make additional offerings.

However, these taboos are not absolute. In modern society, many families still keep the rituals as a way of respecting tradition, while at the same time relying on science and technology to ensure construction quality and workplace safety. The taboos should be seen as an aspect of spiritual culture that gives people faith and peace of mind when starting an important undertaking, rather than something to worry about excessively or to take to superstitious extremes.

Conclusion

Folk taboos for ground-breaking, house-building and house-warming are an important part of the spiritual life of Vietnamese people. Understanding these rules clearly not only helps you avoid unlucky things but also shows respect for tradition, for the land and for ancestors. However, a balanced view is needed, combining the spiritual element with practical science, so that every building is not only physically solid but also spiritually at peace.
