Who are the Xinh Mun and how are their names recorded?
The Xinh Mun are one of the 54 ethnic groups recognised in Vietnam, with the self-name Xinh Mun and other names Puoc, Xa, and Pna, and recognised local groups including Xinh, Mun Da, and Xinh Mun Nghet. In the list of 54 ethnic groups, they are recorded at number 33, living mainly in Son La and Lai Chau.
According to the Survey of 53 Ethnic Minorities of 1 April 2019, the Xinh Mun population is 29,503. Previously, according to the 2009 Population and Housing Census, the figure was 23,278. Citing both data points helps readers see how the statistics have changed over time rather than giving a single number.
A clear distinction is needed: Xinh, Mun Da, and Xinh Mun Nghet are local groups within the Xinh Mun ethnic group, not separate ethnic groups. The list of 54 Vietnamese ethnic groups was issued with Decision No. 121-TCTK/PPCD of 2 March 1979 by the General Statistics Office, and this is the classification basis used consistently in state documents.
Where do the Xinh Mun live and what is their settlement history?
The Xinh Mun are concentrated mainly in Son La and Lai Chau, in Vietnam's northern mountainous region. Sources on the community of 54 ethnic groups record that they have long lived in the northwestern part of Vietnam.
The residential areas of ethnic minorities in the northern mountainous region generally have fragmented terrain, difficult transport, and exposure to natural disasters such as flash floods, landslides, and severe cold. This is the general context noted in materials on Vietnam's ethnic communities, and it is also the familiar living condition of many ethnic communities in the northern mountains, including the Xinh Mun.
Like many other ethnic minorities, the Xinh Mun live in communities interwoven with other ethnic groups in the same area. This interweaving is a common feature of northern mountain populations, and it explains why many cultural elements of the Xinh Mun, especially clothing, are close to Thai culture.
What language do the Xinh Mun speak?
Xinh Mun belongs to the Mon-Khmer language group of the Austroasiatic language family. This group is present among many ethnic minorities in Vietnam such as the Khmer, Ba Na, Xo Dang, Co Ho, Mnong, Bru-Van Kieu, Kho Mu, Ta Oi, Co Tu, and others.
One feature emphasised in the sources is that the Xinh Mun are good at Thai. This reflects long and close exchange with the Thai community in the region. In the past, some Xinh Mun knew the Thai script, while today they use the national script. The shift to the national script in education and administration is a general trend among many ethnic minority communities in recent decades.
What livelihoods do the Xinh Mun rely on?
Their main production activity is upland rice cultivation, with a few doing wet-rice farming. This is a fairly common economic feature among northern mountain ethnic groups, where steep terrain and limited water make swidden farming the mainstay.
Besides rice cultivation, the Xinh Mun economy is tied to the forest and forest products. Their common means of transport is a basket carried with a strap across the forehead, a familiar tool in the mountains suited to steep terrain and to carrying produce, firewood, and water in daily life.
In cuisine, the Xinh Mun eat glutinous and ordinary rice, like spicy seasoning, drink ruou can, and have the custom of betel chewing and blackening their teeth. Betel chewing and teeth blackening were once widespread among many Vietnamese ethnic groups, and among the Xinh Mun they are recorded as a cultural practice.
What is notable about Xinh Mun houses and how they are built?
The Xinh Mun live in stilt houses. The roof is vaulted in the shape of a turtle shell. This architectural feature also appears among many Mon-Khmer speaking groups and among the Black Thai: the gable roof is often built in a rounded, turtle-shell curve.
House-building customs among the Xinh Mun are clearly communal: when someone builds a house, the whole village comes to help, so the house is finished in just a few days. They usually build after the harvest. Land selection is done by divination to see whether the land suits the household members.
In the local day-counting system, water days, comprising the 2nd, 6th, 8th, and 9th of the month, are considered suitable for house building, while fire days, the 1st and 7th, are avoided. The maternal uncle plays an important role in the house-raising rite: he erects the main post, on which are hung many objects symbolising the family's prosperity and fullness, such as rice ears, a knife, a chopping board, and symbols of yin and yang. The maternal uncle also lights the first fire on the new house's cooking stove, and that fire is kept burning through the first night.
How are Xinh Mun social relations and marriage organised?
Small, patrilineal families are the norm, but extended families of three generations, or married brothers living together in one house, still persist quite strongly. Households number about 10 to 15 people, and some reach 20 to 30. The Xinh Mun have many surnames, but the two most common are Vi and Lo.
In marriage, bridegroom service is common. In the past, a son had to serve in his wife's family for about 8 to 12 years, or for life if the wife's family had no son. In the wedding rite for bridegroom service, the bride and groom must exchange their names for a new shared name. This shared name is given by the bride's parents and the maternal uncle, sometimes requiring a yin-yang divination to find it. The bride coils her hair upward on the crown of her head, a sign that she is married.
The wedding sequence also has its own features. On the very day of the bridegroom-service wedding, the newlyweds return to the groom's house for 2 or 3 days before moving to the bride's house for the full period of service. The wedding bringing the bride to the groom's house is held after the service period ends, when the couple already has one or several children. The return-greeting ceremony is held a few days or a year later.
Regarding childbirth, pregnant women still go to the fields and forest until the day of birth. The mother gives birth sitting beside the cooking stove, inside the house. The mother-in-law, the husband, or an elderly neighbour assists. The umbilical cord is cut by pulling it out to the child's ankle, tying a knot, pulling out another stretch in the same way, and then cutting. The placenta is placed in a bamboo tube and hung on a tall tree where few people pass. Only when the child is nearly one year old is a ritual specialist invited to perform the naming ceremony.
What does Xinh Mun worship include?
The Xinh Mun worship ancestors of two generations, parents and grandparents. The symbol of the ancestral place of worship is a pig's jawbone, a little betel on a rice basket lid, and a bamboo tube of water. Offerings are made on occasions of new rice, weddings, and new houses.
Ancestor worship, depending on the place, may be handled only by the eldest brother, or jointly by the brothers. The wife's parents are worshipped separately in a small hut beside the house, and the offering rice is cooked outside the house. The annual village worship ceremony is held in high regard.
It is worth noting that the sources clearly state the local variation in assigning worship duties. This shows that even within one ethnic group, ritual practice can differ between localities, and such difference should not be reduced to a single model.
How do Xinh Mun funerals take place?
When someone in the house dies, gunshots inside the house signal the news. At the same time, a son throws the cooking trivet into the ancestral worship place to express a traditional anger. All daily taboos of the family and of the son-in-law are then lifted. People cook rice on the warming stove, lay the rice-cooking pot crosswise to the house, and the son-in-law handles all the cooking.
The Xinh Mun do not use wooden coffins but only wrap the body in matting. Grave land is chosen by throwing an egg over the intended area: wherever the egg breaks, the grave is placed there. The grave house is carefully made, with all things needed to symbolise the dead. The Xinh Mun have no reburial or grave-visiting customs.
Choosing a grave by throwing an egg is a familiar ritual technique among many ethnic groups in the northern mountains and Southeast Asia. Its appearance in Xinh Mun funerals shows the broad exchange of belief patterns in the region rather than an entirely isolated trait.
What are Xinh Mun festivals and artistic activities like?
The Xinh Mun enjoy singing and dancing on festival occasions, right in the house. Boys and girls, men and women, sing in alternating verses quite naturally. Antiphonal singing is a common form of artistic activity among many ethnic groups, and among the Xinh Mun it is tied to festivals and community gatherings.
In addition, the annual village worship ceremony is the most highly regarded ritual occasion in Xinh Mun spiritual life. Village worship is a communal rite of the residential unit, praying for the village's peace and a good harvest. It is tied to the residential unit rather than only to individual families, so it plays a role in community cohesion.
How is Xinh Mun clothing influenced by Thai dress?
Xinh Mun clothing resembles Thai clothing. The Xinh Mun women's outfit, though deeply influenced by Thai dress, still keeps its own way of wrapping the headscarf. This is a clear example that cultural exchange is not one-way: the Xinh Mun adopted many elements from Thai dress while maintaining some distinctive markers.

What should be noted when learning about the Xinh Mun?
The information above is based mainly on materials from the state agency managing ethnic affairs and the list of 54 ethnic groups. This is a systematic source, but like any ethnographic material it describes common features rather than covering every variation in every village.
Some points need to be distinguished correctly. First, Xinh, Mun Da, and Xinh Mun Nghet are local groups, not separate ethnic groups. Second, other names such as Puoc, Xa, and Pna are names that once existed in the records, not self-names. Third, customs such as 8 to 12 years of bridegroom service, or lifelong service if the wife's family has no son, are recorded as past customs and are not necessarily practised intact everywhere today.
When learning about any ethnic group, it is necessary to distinguish clearly between statistical data for each period, descriptions of customs in ethnographic materials, and contemporary practice in each locality. These three layers of information do not replace one another, and differences between them are normal, not a sign that one source is right and another wrong.
