Boys play with a smart phone as they visit Wat Pratthat Doi Kongmu during the Poi Sang Long novice monk ordination rituals in northern Thailand's Mae Hong Son, April 1, 2017. Considered as one of the biggest moments in a boy's life, the Poi Sang Long novice monk ordination rituals are held every year by the Shan peoples, also known as the Tai Yai, who mainly dwell in Myanmar and northern Thailand. Aged between 7 and 14 years old, the boys, called "Sang Long" in the Shan language, will undergo a series of ritual procedures during a typical Poi Sang Long that lasts for three to four days: hair-shaving, going on temple pilgrimages, attending a grand parade and visiting family relatives, until they are eventually ordained as novice monks at the temple.
