Ancestor sacrifice is often held after the harvest sacrifice, or combined with the harvest sacrifice, with the purpose of praying for a bumper harvest, prosperous future generations, health and safety, and also with the meaning of thanking and offering new valleys to ancestors. Rites vary slightly from place to place. There are three kinds of performing groups of ancestral sacrifice: the first is the clan of pure kinship groups, such as the "La Lumaan" of the Ami; The second kind is the sacrificial group of kinship group and regional group, such as "Jiaxiyalang" of Saixia nationality; The third kind is kin, for example, the Atayal people take "Gege" as the unit of ancestor worship. Ancestor sacrifice is usually held regularly every month or at the time of sowing sacrifice and harvest sacrifice, and wine and meat are also used to sacrifice ancestors as a prayer when temporary accidents occur. For example, in the early morning of the memorial day, each family of the Dake embedded ethnic group smashed millet and kneaded it into a rice ball, and each parent took the rice ball to the priest's house and wrapped it with a pine leaf and hemp. The priest's house prepared a tree stand or bamboo in advance and tied it with the rice ball. Then, the priest led the way, and the parents followed them with rice balls, and they went to the mountains and trees, and then they tied the rice balls to the branches, and the priests shouted the names of the ethnic groups and sang greetings; After the sacrifice, they returned to the club together and began to feast. The ancestral sacrifice of Saixia nationality takes the regional sacrifice group as the unit, and the parents of the people gather in the priest's house, and a "sacred bag" is hung on the beam of the priest's house as the shrine of the ancestral spirit. On the day of the sacrifice, everyone took a handful of waxy millet to the priest's house and mashed it into a cake. The priest steamed rice as a meal to worship the ancestors' spirits, sang a toast and prayed for protection. After the sacrifice, each family shared the cake and enjoyed it. It was the day when each family began to feast.
Another example is paiwan's "Five-year Sacrifice", which is a complex ancestral sacrifice, held jointly by various aristocratic families. Traditionally, there are one, two, three, five and six years of ancestral ceremonies. One year's sacrifice is a small family sacrifice, and five years' sacrifice is a big sacrifice, and then it is merged into a five-year sacrifice, which is held every five years. Usually held after the harvest of millet or sweet potato. Before the sacrifice, the priest Buri sent people up the mountain to collect bamboo and vines, make bamboo poles for rattan balls and thorn balls, make wine, make cakes, kill pigs and clean up the site. Housewives set up a sacrifice, and invited the ghosts who died suddenly and violently to take a cool rest on the stone bench with green bamboo, so as not to disturb the ancestors' visit again. Then, they set up a sacrifice to worship the ancestors in front of the house, behind the cemetery and other places, and watched the unprecedented rattan ball ceremony with the ancestors. On the sixth day of the Five-Year Festival, there were two activities, namely, a thorn ball contest and a dance. In the thorn ball contest, the leader threw a cane into the air, and the young people each held a bamboo gun to stab it, and the winner was the one who stabbed the most times. The dance is attended by the youth of the whole village, and the biggest person in the village invites the youth of the whole village to have a dinner and dance. These two activities are also the last programs of the adult ceremony. During the ceremony, young people wear thatched knots at their doorsteps and bodies to show that evil spirits are banished. The ceremony is always full of auspicious atmosphere of entertaining the gods and pleasing their ancestors and praying for the blessings. Finally, the priest led the tribe members to hunt in the mountains, and the sacrifice was completed.
The ancestor worship ceremony of the Silaya people in Pingpu is called "Panna Buddha". They believe that ancestral spirits are stored in clay pots called "An Gan Hu", which are generally enshrined on the altars of tribal clubs or homes. The number and decoration vary from tribe to tribe, and there are generally three, with red cloth on the neck and banana leaves in the mouth. Clear water is filled in the tank, and the water is changed once at the beginning of the month or half of the month. Usually, rice cakes, walnuts and animal bones are sacrificed. Sacrificial ceremonies vary from tribe to tribe, usually three times a year: "half-year sacrifice" on June 16 th of the lunar calendar; "Harvest Festival" on August 18th; On September 16th, Zuling's birthday, the ceremony was grand. Three elders each held a Zuling jar, praying for the ancestors to bless the whole family's longevity, and then took the clear water from the jar and sprinkled it on the ground. At that time, all the sacrifices will be rice cakes, pork and millet wine, and they will feast and dance day and night.
The traditional ancestor worship ceremony of Pingpu and Anya people is called "Mabuhanwag", which is traditionally held on July 20-22 in the lunar calendar for three days, with the unmarried teenager "Mada" as the main sacrifice. Teenagers who participated in ancestor worship held a race at dawn, starting from the village and turning back to the ancestral spirit, indicating that they inherited the martial arts of their ancestors, and the winner was awarded a flag by the leader. The next day, the ancestors were formally worshipped. Teenagers bathe their hair, bound by straw ropes, carry long guns, worship their ancestors with glutinous rice balls, banana leaves and thatch, and sing songs to thank their ancestors for their blessings. On the third day, the leader led the crowd out hunting, and the whole village feasted and danced. Teenagers dressed in national costumes went to the leader's house for a feast and paid tribute to the leader and elders. Singing while drinking, dancing, and excitement. An old woman drummed for the festival, and everyone responded and sang songs of praise to the ancestors to comfort the ancestors, and the sacrifice ended.
The sacrificial activities of the Atayal people to celebrate the harvest and reward the ancestors of the gods are called "Malodoan". It is usually held in June after millet harvest and lasts for one month. "Gaga" * * * Priests led the public to go hunting for several times, and the prey obtained for the first time was equally distributed among the members. The rest is reserved for the harvest festival. During hunting, just keep the taboo. If there are casualties or other ominous signs, it means that someone has violated the taboo, and the gods will not allow it. Immediately stop hunting and postpone the harvest festival for one month. Third, the harvest festival will be cancelled automatically.
