Mae Hong Son’s most famous and colourful festival is Poy Sang Long, held over the first weekend of April, which celebrates the ordination into the monkhood, for the duration of the schools’ long vacation, of Thai Yai boys between the ages of 7 and 14. Similar rituals take place in other northern Thai towns at this time, but the Mae Hong Son version is given a unique flavour by its Thai Yai elements. On the first day of the festival, the boys have their heads shaved and are anointed with turmeric and dressed up in the colours of a Thai Yai prince, with traditional accessories: long white socks, plenty of jewellery, a headcloth decorated with fresh flowers, a golden umbrella and heavy face make-up. They are then announced to the guardian spirit of the town and taken around the temples. The second day brings general merry-making and a spectacular parade, headed by a drummer and a richly decorated riderless horse, which is believed to carry the town’s guardian spirit. The boys, still in their finery, are each carried on the shoulders of a chaperone, accompanied by musicians and bearers of traditional offerings. In the evening, the novices tuck into a sumptuous meal, waited on by their parents and relatives, before the ordination ceremony in the temple on the third day.
