The Water-sprinkling Festival happens in the middle of April (the sixth month on the Tai calendar) and lasts from three to five days. It is a favorite festival of the ethnic groups of Dai, Achang, De’ang, Bulang, and Wa. Celebrations include dragon boat racing and water sprinkling. It is believed that the water sprinkle onto someone or even get him or her soaked will bring that person good luck. The tradition of water sprinkling originates from a legend of seven young women who killed a monster that they were forced to marry. They cut its head off with his own hair. However, they had to hold its head by turns because the head would produce flames when it touched the ground. The girls would pour water over the girl who had held the monster’s head for the past year in order to wash the monster’s blood stains from the girl’s clothes.
