The festival is a traditional custom of the Thai ethnic group in Moc Chau, held on the 15th day of the second lunar month every year. Before the festival, people prepare products associated with their daily life to make offerings.

This is the most important festival of the White Thai people in Muong Sang commune, Moc Chau district, including ritual and festive parts. During the ritual, under the ‘neu’ tree decorated with eye-catching motifs, the shaman will read a prayer to Then (heaven) to show him the suffering of the villagers when there is no rain and beg him to deliver rain for fields and trees to develop. At the end of the prayer, Then will announce that he will give water to the villagers, so that they will have a year of good weather and bumper harvests.

At the festival, the Organizing Committee also held many cultural and art activities and Xoe dances with the participation of a large number of people and tourists.

The organisation of the Rain Praying Festival aims to preserve and promote the unique traditional cultural beauty of the White Thai ethnic group in Moc Chau district. It also contributes to boosting tourism development, attracting more and more tourists to the Moc Chau National Tourist Area.
