46. Bo Y Ethnic Group – A Distinct Identity Among The Ethnic Groups In Vietnam
History
The Bo Y ethnic group is one of the smallest communities among the ethnic groups in Vietnam. Their ancestors are believed to have originated from a branch of the ancient Lac Viet people. Over time, they developed their own identity while maintaining connections to early Vietnamese cultural roots.

The Bo Y people also use various self-names such as Bo Y, Bo Trong, Bo Mai, Lieu, Trong Gia, Ly Lieu, and Di Lieu. Today, the term “Bo Y” generally refers to two groups: the Bo Y (Pu Y) in Ha Giang Province and the Tu Di group in Lao Cai Province. Despite their small population, they have preserved many traditional customs and cultural values.
Language
The Bo Y language belongs to the Tay–Thai branch of the Tai–Kadai language family, mainly used by the Bo Y group in Ha Giang. Meanwhile, the Tu Di subgroup in Lao Cai uses a language from the Sino–Tibetan family, reflecting linguistic diversity within the community.

This dual-language system highlights their historical interactions with different ethnic groups. Today, many Bo Y people can also speak Vietnamese, which supports communication and integration while still maintaining their native languages.
Geographic Distribution
The Bo Y people mainly reside in northern mountainous regions. The Bo Y group in Ha Giang Province lives in several communes of Dong Van and Quan Ba districts. Meanwhile, the Tu Di group is found in parts of Lao Cai Province.

Their settlements are often located near water sources, which support wet-rice cultivation. The surrounding landscape consists of mountains and valleys, shaping both their agricultural practices and daily life.
Religion And Beliefs
The Bo Y people have a unique worldview that divides the universe into three layers. The human world exists in the middle, while the world of gods and spirits lies above, and an underground world exists below.

Their beliefs combine animism and spiritual practices, with rituals conducted to honor deities and maintain harmony between different realms. Before building a house, for example, they perform ceremonies to worship the earth god and pray for safety and prosperity.
Festivals
Festivals of the Bo Y people are closely tied to agricultural cycles and spiritual beliefs. These events often include rituals to pray for good harvests, health, and prosperity.

Community gatherings during festivals strengthen social connections and preserve traditional customs. Offerings, including food and livestock, play an important role in these ceremonies, reflecting both spiritual and economic aspects of their culture.
Costumes
Traditional clothing of the Bo Y people is simple but carefully crafted. Men typically wear indigo-dyed shirts with collars and matching trousers, reflecting practical design for daily work.

Women wear more elaborate outfits, including five-piece shirts decorated with colorful patterns along the edges. In the past, silver jewelry was also used, although it was not very common. These costumes highlight both aesthetic values and cultural identity.
Economic Conditions
The Bo Y people have a long tradition of wet-rice cultivation and are considered skilled farmers. Today, they practice more intensive agriculture, combining rice farming with the cultivation of crops such as maize, cassava, chili, soybean, tea, tobacco, and sugarcane.

Animal husbandry also plays an important role in their economy. Poultry farming, especially raising chickens, is common and supports both daily consumption and ceremonial needs. With improved agricultural practices and government support, their economic conditions have gradually become more stable.
47. La Ha Ethnic Group – A Traditional Community Among The Ethnic Groups In Vietnam
History
The La Ha people are one of the long-established communities in the Northwestern region of Vietnam. They have lived in this area for generations, maintaining their cultural identity despite interactions with other ethnic groups.

They call themselves La Ha, Kla, or Phlao, while other groups refer to them by various names such as Xa Khac, Phlac, or Bu Ha. The La Ha are divided into two main subgroups: La Ha Ung, who practice wet-rice farming, and La Ha Phlao, who focus on upland cultivation.
Language
The La Ha language has been influenced by long-term interaction with neighboring communities. Due to living alongside the Black Thai people, many La Ha individuals are bilingual and commonly use the Thai language in daily communication.

In addition to their mother tongue, many La Ha people can speak Vietnamese, especially younger generations. Some also understand languages such as H’Mong, Dao, and Muong, reflecting a multilingual environment shaped by interethnic contact.
Geographic Distribution
The La Ha people mainly reside in the Northwestern mountainous region of Vietnam. Historical records indicate that they were already present in this area when Thai groups migrated there between the 11th and 12th centuries.

Their settlements are often located in mountainous and upland areas, where natural conditions support traditional farming practices. These regions are typically remote, contributing to the preservation of their cultural traditions.
Religion And Beliefs
The La Ha people follow animism and believe in the existence of various spirits. They worship many types of “ghosts,” each associated with different aspects of life and nature.

Ancestor worship is also practiced, but it is limited to two generations, mainly parents. The La Ha maintain strict taboos in daily life, especially regarding sacred places such as ghost forests and family altars. These beliefs play an important role in shaping their social behavior and cultural values.
Festivals
Festivals of the La Ha people are closely linked to agricultural cycles and spiritual beliefs. These events often include rituals to honor spirits and ensure favorable conditions for farming.

Community gatherings during festivals provide opportunities for social interaction and cultural expression. Traditional music, food, and rituals are essential elements that help preserve their heritage.

Costumes
Traditional costumes of the La Ha people reflect both practicality and cultural identity. Women often wear shirts with silver buttons, black skirts, and blue waistbands, along with embroidered Pieu scarves. Their hair is typically styled in a bun, especially after marriage.

Men’s clothing is simpler, consisting of indigo-dyed shirts, loose trousers, and headscarves. In the past, women also wore various types of jewelry such as silver earrings, necklaces, and bracelets, adding to their distinctive appearance.
Economic Conditions
The La Ha people mainly rely on upland farming as their primary livelihood. They grow crops such as glutinous rice, maize, cassava, and cotton. Only a small number of households practice wet-rice cultivation alongside upland farming.

In addition to agriculture, fishing and gathering contribute to their income. Weaving was also relatively developed in the late 20th century, with skilled techniques. Today, trading often takes place within villages or at local markets, where agricultural products and handicrafts are exchanged.
48. Cong Ethnic Group – A Lesser-Known Community Within The Ethnic Groups In Vietnam

Their spiritual life is closely connected to agriculture and nature. Rituals are performed to seek protection, ensure good harvests, and maintain harmony between humans and the natural world.
Festivals
Festivals of the Cong people are closely tied to agricultural cycles. Every year, in the third lunar month, villages organize ceremonies before sowing seeds. During this time, symbolic barriers are placed at village entrances to restrict movement and maintain sacred space.

Families also perform rituals in their fields and homes to pray for protection against animals and natural threats. These ceremonies reflect their deep connection to farming and seasonal rhythms.

Religion And Beliefs
The Ngai people believe that humans consist of both body and soul, and that the soul continues to exist after death. This belief shapes their funeral practices, which often include burying personal belongings with the deceased.
They worship a wide range of deities, including ancestors, gods, Buddha, forest spirits, and other supernatural beings. Each type of worship involves different rituals and offerings, reflecting a rich and diverse spiritual life.

In addition to farming, they raise livestock such as buffaloes, pigs, and poultry, and engage in handicrafts and trade. Living in areas with convenient transportation also allows them to participate actively in market and service activities.
53. Ro Mam Ethnic Group – A Small Yet Distinct Community Among The Ethnic Groups In Vietnam
History
The Ro Mam ethnic group is one of the smallest communities among the ethnic groups in Vietnam, with a population slightly larger than only a few groups such as the Brau and O Du. Although their exact origin remains unclear, they have lived in Vietnam for a long time.

Over the years, the Ro Mam have experienced significant changes in settlement and population. Today, they have transitioned to a more stable lifestyle, focusing on economic development while preserving their traditional culture.
Language
The Ro Mam language belongs to the Mon–Khmer group within the Austroasiatic language family. This linguistic classification connects them with several ethnic groups in the Central Highlands and surrounding regions.

In addition to their native language, many Ro Mam people can communicate in Vietnamese and other local languages. This multilingual ability reflects both integration and cultural interaction.
Geographic Distribution
Historically, the Ro Mam lived in multiple villages across Kon Tum Province, often alongside the Giarai people. However, due to various historical changes, their population has significantly decreased.

Today, they mainly reside in a single village in Mo Rai Commune, Sa Thay District, Kon Tum Province, near the Vietnam–Cambodia border. This concentrated settlement makes their community both unique and vulnerable.
Religion And Beliefs
The Ro Mam people believe that all things possess a spirit, reflecting a strong animistic worldview. Among these beliefs, the rice spirit holds a particularly important role in their spiritual life.

They perform rituals throughout the agricultural cycle, from clearing fields to harvesting rice. These ceremonies express their respect for nature and their hope for prosperity and protection.
Festivals
The most important festival of the Ro Mam people takes place after the harvest season. This is a major community event that includes rituals, celebrations, and social activities.

Following the new rice festival, weddings and ceremonies for the deceased are often organized. Festivals play a central role in maintaining cultural continuity and strengthening community bonds.

Costumes
Traditional costumes of the Ro Mam people are simple yet distinctive. Men typically wear white loincloths, while women wear skirts made from undyed fabric and sometimes go topless or wear simple tops.

Accessories such as earrings made of wood or ivory are common. Cultural practices like tooth filing during adulthood also reflect their traditional identity.
Economic Conditions
The Ro Mam people primarily rely on agriculture, with sticky rice as their main crop, along with maize and cassava. Farming remains the backbone of their livelihood.

54. O Du Ethnic Group – A Distinct Community Within The Ethnic Groups In Vietnam
History
The O Du ethnic group is one of the smallest communities among the ethnic groups in Vietnam, with a long history in the north-central region. Historical records show that they have lived for generations in what are now Tuong Duong and Ky Son districts of Nghe An Province.

They call themselves “O Du” or “I Du” and are also known as “Tay Hat.” Despite their small population, the O Du have maintained their cultural identity through close community ties and traditional practices passed down over time.
Language
The O Du language belongs to the Mon-Khmer group within the Austroasiatic language family. However, due to their small population and close interaction with neighboring groups, their native language is less commonly used in daily life.

Today, most O Du people communicate using Khmu or Thai languages. This linguistic shift reflects both cultural exchange and the influence of surrounding ethnic communities in the region.
Geographic Distribution
The O Du people are mainly concentrated in Tuong Duong District, Nghe An Province. This mountainous area provides the natural environment in which they have lived and adapted for many generations.

Their settlements are often located near other ethnic groups, leading to strong cultural interaction. This proximity has shaped many aspects of their daily life, including language, customs, and social organization.
Religion And Beliefs
The O Du people believe that every person has a soul that continues to exist after death. When someone passes away, their soul becomes a spirit, with one part remaining in the home and another residing in the cemetery.

Ancestor worship plays an important role in their spiritual life. Rituals are performed to honor the deceased and maintain a connection between the living and the spiritual world. These beliefs guide many aspects of family and community traditions.
Festivals
The O Du celebrate major traditional festivals such as the Lunar New Year and the New Rice Festival. These occasions bring the community together to express gratitude and strengthen social bonds.

One of their most important events is the thunder-welcoming festival. During this ceremony, villagers gather to make offerings to the heavens, often including livestock such as buffaloes, cows, and pigs. The ritual reflects their deep connection with nature and agricultural life.
Costumes
Today, traditional O Du clothing is rarely seen. Most men and women wear garments similar to those of the Thai and Vietnamese people in the region.

In the past, their costumes had distinct features, but over time, these have gradually disappeared. The change reflects both modernization and the strong cultural influence of neighboring groups.
Economic Conditions
The O Du people mainly rely on agriculture and animal husbandry for their livelihoods. Farming remains the primary source of income, supported by raising livestock and poultry.

They also produce household items from bamboo and rattan and engage in simple weaving activities. Although economic conditions are still developing, access to electricity and clean water has improved, helping to enhance their quality of life.
