Men got married at the age of 21. The groom's relatives engaged in matchmaking. It was necessary to present a gift to the groom's parents or the bride's girlfriends. In some communities, the bride and groom exchanged broken front teeth. Accepting the gift meant agreeing to the marriage. Economic ties were weak, and families easily broke up at the initiative of either side.
Violation of religious prohibitions was considered the most serious of crimes for which there was a fine in the form of rice, meat, skins or wine. Theft, murder, and adultery were considered crimes. In such cases, the custom of revenge was in effect.
The plaintiff and the defendant fought a duel. For his wife’s adultery, the husband took 2 or 3 pigs from the opponent. The Taiwanese worshipped the spirits of the mountains and the sea and sacrificed to them with meat and fish, sprinkling them with water. If a person died in battle the bodily remains were sacrificed to the spirits. The corpse was placed in a small hut, built on the branches of a tree, and shot at with bows or covered with a pile of stones into which a flag was placed.
As we can see, the cult of ancestors, fetishism, and animism was widespread among the tribes. The interpretation of dreams was also popular. The tribal pantheon had paired Deities. We believe that they symbolized both masculine and feminine principles.
The main Deities were Tamagisanchak – the god of rain, and Takarupada – the goddess of thunder, representing beauty and fertility.
Hamo and Pagatao were associated with a solar cult. All tribes believed in good and evil spirits of nature, semi-mythical heroes. The cult of human ancestors and the cult of plant ancestors were widespread. The agricultural cycle was associated with seven holidays accompanied by ritual libations and orgies.
In the 19th century, the funeral rites changed, the body of the deceased being interred without ceremony in an undesignated place. Some tribes preserved legends about the flood, after which the surviving brother and sister became husband and wife and many aborigines descended from them. In folklore, many stories were about shooting at the sun. This plot is reminiscent of the Chinese legend about the archer Yi, the sun and the moon pursuing each other and the immaculate conception, the emergence of agriculture, hunting, fishing, plants and animals.
