The next day, the Dai language is called "angry day" (empty day); The third day is the first day of the New Year, and it is called "Overlord Horse", which is actually the beginning of a year. People think this day is the most beautiful and auspicious day. In the early morning of the festival, Dai men, women and children put on festive costumes and carried clear water. They first went to the Buddhist temple to bathe the Buddha, and then began to splash water on each other to wish each other luck, happiness and health. People are dancing and shouting "water! Water! Water! " The sound of gongs and drums is soaring, and the water is splashed everywhere. The scene is really spectacular.
