Poi Sangken is the major festival of the Tai Phakes. It is similar to Songkran which is celebrated in Thailand. It marks the beginning of new year in the Tai calendar. It is celebrated for three days. Basically, it starts from 13 or 14 April every year. In this festival, people throw water on each other which signifies washing away the sins of one another. They also cleanse Buddha images and statues from household shrines as well as from monasteries by gently pouring water over them.
