TL;DR: The Mang are one of Vietnam's 54 ethnic groups, self-named Mang, living mainly in the Nặm Ban area of Sìn Hồ district, Lai Châu province. Their language belongs to the Mon-Khmer group within the Austroasiatic family, and many Mang also speak Thai. Their spiritual life centers on house spirits, village spirits and Dam spirits (ancestors and lineages), along with a cycle of agricultural rituals such as the swidden sowing ceremony, rice soul offerings, the rice mother rite and the New Rice festival after the October lunar harvest.
Who are the Mang and where do they live?
The Mang are one of Vietnam's 54 ethnic groups, self-named Mang. Other recorded names include Mang U, Xá Mảng, Nieng O, Xá Bá O and Xá Cang Lai. The Mang now live mainly in Lai Châu province, concentrated in the Nặm Ban area (also recorded as Dum Bai) in Nặm Ban commune, Sìn Hồ district, long regarded as the "homeland" of this ethnic group.
According to the official list of Vietnam's ethnic groups, the Mang have two recorded local subgroups, Mảng Gứng and Mảng Hệ. These are subgroups of the same ethnic group, not separate peoples.
Population figures differ across sources and dates. The 2009 Population and Housing Census recorded about 3,700 Mang. The Survey of 53 Ethnic Minorities of 1 April 2019 gave 4,650. The gap reflects different survey dates and collection methods, not a substantive contradiction.
Origins and place among Vietnam's peoples
Legends and stories still told in the Nặm Ban area indicate the Mang are one of the indigenous groups of the northwest. This is a claim recorded in introductory materials about the Mang, based on local legends rather than firmly established archaeological or linguistic conclusions.
In the list of 54 ethnic groups, the Mang rank 44th, alongside groups such as the Chut, Cờ Lao and Bo Y. Their recorded area of residence is Lai Châu province.
Which language group does Mang belong to?
Mang belongs to the Mon-Khmer group within the Austroasiatic family. This group is spread widely across mainland Southeast Asia and includes many peoples in Vietnam such as the Khmer, Ba Na, Xơ Đăng, Cơ Ho, Mnong, Khơ Mú and Bru-Van Kieu.
A notable feature is that many Mang speak Thai, reflecting long contact and multi-directional relations with Thai communities living in the same area. Historically, the traditional social organization of the Mang was once dominated by Thai social organization, though the village (muy) structure was maintained according to traditional custom.
Mang in the linguistic picture of the northwest
The coexistence of Mang and Thai in the northwest shows how complex the region's linguistic picture is. A community may use its mother tongue within the family and lineage while using Thai for inter-community communication. This is common in many mountainous areas of Vietnam where ethnic groups live intermingled.
What is traditional Mang production like?
The Mang are swidden farmers, living by shifting cultivation. Choosing and marking swidden plots is done after Tet. Around March to April, people clear grass, let it dry and burn it. In May to June they burn the plot and sow seed. Tools include axes, knives and dibble sticks.
According to introductory materials, upland rice yields are often low because of poor soil, secondary forest, precarious livelihoods and year-round food shortages. In recent years some Mang have taken up hoe cultivation and some places have built terraced fields, making rice yields more stable.
Animal husbandry and handicrafts are not strongly developed. The Mang raise buffalo, cattle, goats, chickens and pigs. Gathering and hunting in all four seasons remain important economic activities. Some Mang woven products such as bem, cot and gui baskets are favored by other ethnic groups in the region.
Meals and clothing
The Mang eat two meals a day, at midday and in the evening. Maize is the staple, usually mixed with cassava or a little rice and steamed. Boiled young cassava leaves with salt are eaten almost year-round. The Mang enjoy smoking pipe tobacco and drinking white liquor.
Traditional dress is still preserved, though many now dress like the Thai or Kinh. A distinctive feature of Mang women's dress is a wrap draped around the body, cut from coarse white cloth with a row of red thread embroidered down the middle. The head is left bare, hair tied in a topknot with a tasseled cord, and legs wrapped in leggings. Mang women's dress also includes a white scarf embroidered with thread borders at the waist and chest. When worn, the woman leaves the white bodice and necklace visible. The skirt is dark indigo with a red border at the hem.
Housing and transport
The Mang live in stilt houses made of mixed wood with simple techniques. The common means of transport is the gui basket, carried with a strap across the forehead and a yoke behind the neck. This carrying style is also found among many other peoples in Vietnam and worldwide.
How is Mang society traditionally organized?
The head of traditional Mang social organization is the Pogia. Together with a council of lineage heads, he directs all cultural, religious and social activities in the village. Later this organization was broken up and came under Thai social organization. The village (muy) structure, however, was maintained according to traditional custom.
Each village has a headman who oversees tax collection and corvee labor. A village usually has one large lineage, and lineage heads together with a council of elders run social and religious activities according to custom. The Mang have five main lineages, each taking an animal as its totem.
What are the worship customs of the Mang?
The Mang belief system is rich and plays an important role in spiritual life. The Mang believe in many kinds of spirits, among which the house spirit holds a particularly important place. The house spirit is worshipped at Tet or when someone in the household is ill. Besides the house spirit, the Mang also worship the Dam spirit, meaning ancestors and lineage.
Heaven is conceived as the supreme creator. There is also a legend of human origin following the gourd motif, a motif common in the legends of many peoples in Vietnam and Southeast Asia.
The four-tiered cosmos
The Mang conceive of the universe as having four tiers. Above the sky is the world of creator deities. On earth is the world of humans and spirits. Below the ground is the world of ugly dwarfs. Under the water is the world of dragons. This conception shows a clearly structured cosmology, layered vertically from high to low.
Agricultural rituals and offerings
Every year villagers also worship the village spirit and house spirit to pray for peace. Notably, the Mang have a series of agricultural rituals, including the swidden sowing ceremony, rice soul offering, rice mother offering and post-harvest offering. These are tied closely to the swidden farming cycle, reflecting the central role of rice and farming in community life.
How do the Mang celebrate festivals and Tet?
Besides Lunar New Year, the Mang celebrate the New Rice festival after the October lunar harvest. This is an important occasion for the community to give thanks and pray for the next crop. The new house celebration is a joyful day for the whole village, with many complex rituals expressing ethnic identity.
House-building ritual
Although Mang houses are considered temporary, from choosing land, leveling the site and erecting posts to roofing, a diviner must be consulted for an auspicious date and hour before building begins. This shows the role of spiritual factors in decisions about dwelling and community life.
How do Mang funerals work?
Mang funerals involve many complex rites, from laying out the body to burial. In the past coffins were mainly made of bark or joined bamboo. Later people used hollowed tree trunks or wooden plank coffins.
What are Mang folk arts and games?
The Mang folk song "xoong" is widely known and loved. Historical tales and stories about the group's history are usually told by elders. At festivals, children play shuttlecock and spinning tops. In some places young people play con throwing.

What to note when researching the Mang
Most introductory materials about the Mang on state agency portals are compiled from the same origin or have similar content. Readers may therefore find nearly identical passages across many pages. This does not mean the information has been independently verified many times; it reflects the same source being cited repeatedly.
On population figures, differences between survey dates are normal. Readers should note the date and source when citing, rather than treating a single number as correct for all times.
On local subgroups, Mảng Gứng and Mảng Hệ are two subgroups of the same Mang ethnic group, not two separate peoples. In Vietnam's official list, the Mang are a single group with two recorded local subgroups.
On spiritual life, Mang worship practices such as house spirit and village spirit offerings, the swidden sowing ceremony, rice soul offering and rice mother offering are described in the materials as cultural practices tied to the farming cycle and community organization. Readers can approach these practices as ethnic culture, while noting that they are traditional religious rituals.
