Held biennially on the seventh and eighth days of the Lunar New Year, the Coi communal house festival in Vu Binh commune, Lac Son district, honours Hoang Ba Quoc Mau, her sons - King Cun and King Hai - along with local deities who contributed to agricultural and social development. Beyond its spiritual significance, the festival offers visitors an immersive experience of Muong ethnic culture.

A showcase of traditional Muong attire at the Dinh Coi Festival aims to introduce and promote Muong cultural identity to visitors.

festival highlight, attracting large crowds. Renowned Muong folk artist Bui Van
Chinh expressed pride in preserving and showcasing this cultural heritage,
noting the growing enthusiasm of both locals and tourists.

spiritual tourism event.

customs, and enjoying OCOP-certified specialties. The event not only promotes

The Muong group is one of the largest ethnic minorities in Vietnam, primarily found in Hoa Binh province. The Muong people in Hoa Binh boast a rich and diverse cultural treasure that reflects the unique identity of this ethnic group. Accounting for over 63% of the province's population, they have created and preserved numerous distinctive cultural values, contributing to their unique identity. Their cultural heritage is an invaluable asset, at the heart of their national identity, and represents a vibrant spiritual life that must be preserved and promoted in today’s modern world.
For generations, the ethnic communities of Hoa Binh province, particularly the Muong people, have preserved vibrant festivals deeply intertwined with the region’s geography, nature, and social traditions. These celebrations enrich Hoa Binh’s spiritual life and cultural identity, reflecting both folk beliefs and the intermingling of ethnic customs. Many of these festivals have endured the test of time, passed down through generations and continuing to thrive today. Among them, the Khai Ha (Going Down to the Field) festival stands out as one of the most significant events of the Muong ethnic group.
Muong calendar, known as sach doi, is an ancient folk knowledge system developed through observations of the movement of the pleiades star. This unique calendar consists of 12 bamboo sticks, each representing a lunar month. Specific days within each month are marked with distinct symbols, guiding locals in determining auspicious and inauspicious days for important activities.
Authorities and residents of Chieng Chau commune, Mai Chau district, are making efforts to preserve and promote the historical value of a centuries-old gold apple tree (scientifically known as diospyros decandra lour), which has been recognised as a national heritage tree.
Hoa Binh is home to two types of Dong Son drums: Heger I and Heger II. These drums date back from the 4th century BC to the 5th century AD.
Mo is a term referring to a profession and cultural heritage which integrates folk beliefs with folk culture and arts. Practiced at funerals and religious rituals by the Muong ethnic people, it aims to provide spiritual comfort during significant life events such as illness and death.
