The Poy Sang Long Festival in Thailand is a very colourful and culturally important festival of the Buddhists in the northern part of Thailand, i.e. Chiang Mai and Mae Hong Son. This is an annual ordination festival of the Shan (Tai Yai) ethnic community that temporarily makes young boys novice monks to study and train in Buddhism. The three-day festival is called the Festival of the Crystal Sons and is a mixture of Buddhist rites, community merit making, and spectacular pageantry. Tourists who come to northern Thailand during the period of March to mid-April can see the rare combination of both tradition and spectacle, as processions, music, costume, and temple rituals.
Rooted in Shan Buddhist tradition, the Poy Sang Long ordination festival symbolises Prince Siddhartha’s early life before renunciation. Historically practised in Myanmar and northern Thailand, the ritual highlights community merit-making and Shan cultural identity. Families proudly present their sons, believing the ordination brings blessings and a higher status for the whole family.
Poy Sang Long ordination festival means the Festival of the Crystal Sons. It is mainly concentrated on the ordination as a temporary one of Shan boys as novice monks. Families receive merit, communities restore their cultural sense, and children undergo a rite of passage in their transition from boyhood into monkhood. Innate costumes, courtly pageantry, and religious rituals in the temple portray the symbolism of innocence, purity, and renaissance.
The Poy Sang Long Festival dates vary but typically fall between March and mid-April. Each Shan temple or village chooses its own schedule, so multiple ceremonies take place across the northern provinces. Key locations include Chiang Mai, Chiang Rai, Lampang, Pai, and Mae Hong Son, with Mae Hong Son being the heartland of Shan culture.
These rituals are deeply symbolic, intertwining family pride, communal identity, and Buddhist spiritual practice.
Tip: Arrive early in the morning for the best light and access to key ceremonies.
