Water-Splashing Festival is not only the first Buddhist festival at the beginning of a new year but also the most important festival of the Dai, De-ang and A-chang nationalities.

All people of the village will take a bath and change into new clothes, they then go worship Buddha in the first morning of the Water Splashing Festival. Dragon boat racing and other performances such as peacock dance are held on the first day followed by the characteristic water-splashing event on the second day. The last day is usually for the young people to play games as a way of expressing their love for each other.

People assemble in the Buddhist temple, building sand towers. Then everybody will sit around the tower and listen to the chanting of the Buddhist scriptures. Then again a Buddhist statue will be carried out into the yard and splashed by all women in the village, which is so-called bathing for the Buddha.

After such religious rite, all young people will go out of the temple and splash water on each other for pleasure. All present are involved in the activity.
