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.

Muong folk singing, particularly thuong rang bo meng and hat dup giao duyen, is a 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.

Festival-goers also witness agricultural rituals accompanied by sacred Cheo Dinh dances and resonant gong beats. Considered an auspicious start to the farming season, the ceremonies reflect hopes for favorable weather, bountiful harvests, and national prosperity. The event also fosters community spirit and cultural appreciation.

Following the rituals, vibrant folk performances and traditional games bring the festival to life. First-time visitor Le Diem Thao from Hanoi praised the well-organised festivities, particularly the interactive folk games such as nem con (throwing cloth balls), di ca kheo (stilt walking), and danh mang (bamboo percussion). Ethnic sports like stick pushing and tug-of-war, alongside modern activities like volleyball, further energised the celebrations.

The 2025 festival saw an expanded programme, including a Muong ethnic costume contest with 40 participants and a gong performance competition among hamlet teams.

Deputy Chairman of the commune People's Committee Bui Minh Tang emphasised that the festival, blending tradition with modern cultural exchanges, has become a key spiritual tourism event.

Thousands of visitors attended, engaging in cultural experiences, exploring local customs, and enjoying OCOP-certified specialties. The event not only promotes cultural preservation but also stimulates tourism and economic growth in the region.
