The Sacrifice to the Short Spirits is the most important traditional rite of the Saisiyat tribe, with a smaller ceremony every two years and a large one every 10 years. The festival is held around the 15th day of the 10th lunar month, at the end of the harvest season, and lasts for four days and three nights.
The first day of the festival starts with welcoming of the spirits, when tribal elders offer wine and meat and then, facing to the east, pray to welcome the Short Spirits. The second day is for entertaining the spirits, which is the centerpiece of the entire festival. The tribe's people engage in festivities and dancing to commemorate the Short Spirits. On the last day, rites for sending off the spirits off are performed. At the appropriate time, the tribes throw sheaves of grass and hazelwood sticks toward the east, signifying that the Short Spirits have already departed. After that, the rice wine, pork, and rice cakes that were offered to the spirits are given to the participants, bringing the festival to an end.
