First of all, it is for the need for survival. In the primitive society, in the process of fighting against nature, in order to protect themselves and avoid the damage of beasts, we often wear the beast skin, corners and other things on their heads, arms, wrists, or feet. It is to confuse each other as a prey to confuse each other. On the other hand, these beast skin is a weapon for defense or attack. As for those small gravels, small animal bones or animal teeth hanging on the neck, waist, or on the wrist, in addition to the earliest unconscious decorative behavior of human beings, its real role is probably for counting or notes.

Secondly, it is a symbol of power. In a very rude primitive society, humans need to ask for food from nature and overcome the fierce beasts, which undoubtedly require courage and strength. From the perspective of primitive people, the reason why beasts are full of strength, its sharp minions, hard bones, and beautiful fur must play an important role. Therefore, after the human beings capture these beasts, they can eat their bones, teeth, etc. into their bodies, thinking that they can draw the power of the beasts so that they can defeat the fierce beast with it. It seems that from these primitive jewelry, the primitives have received some spiritual comfort and strength.

On the other hand, the more a person wears like this and the "jewelry", the more likely he will wear more and more valuable jewelry. In fact, these brave people often like to use some bright and eye -catching, easy -to -recognize body decorations, such as beautiful feathers, beasts' teeth, rare shells, and even valuable "beautiful stones" (jade "(jade). To show and show off your strength and authority. In "On the Art", Pricanov said: "These things were first worn only as brave, dexterous and powerful marks, but later. It was because they were brave, dexterous and powerful, so they started to cause The feeling of aesthetics is into the scope of the decoration. "

Third, it is a totem worship. The sun, moon, stars, and storms, these are originally ordinary natural phenomena; but from the perspective of primitive people, these things have some magical power. The primitive people get along with nature, and they are accompanied by the sun, the moon, the stars, the river, and the flying beasts. They worship the substances given to them to survive by these natures. Over time, this material is deeply printed in their minds and has become a totem with magical power. The right of them regarded it as their ancestors or protecting God, or worshiped the blood relatives of the Ben clan and the tribe. At the beginning, in order to allow these totems to protect themselves, human beings assimilated themselves to these totems. Slowly, people incorporated these totems into their jewelry, and made their jewelry into the image or shape of these totems, such as the sun, the full moon, and the full moon; wait.

Fourth, as a amulet. Engels pointed out: "In ancient times, people still did not know their physical structure at all, and affected by the scenery of the dream, they produced a concept: their thinking and feeling were not their physical activities, but a unique one, but a unique ones. , Activities in the soul of the body when they die in this body. "The primitive people believe that everything has a soul, and the soul is divided into good and evil. The disaster and disease are evil spirits. In order to prevent those evil spirits from approaching, at the same time, they can be protected by good spirits, and they use ropes to wear shells, small gravel, feather, animal teeth, leaves and fruits. They believe that these things have a kind of thing. The supernatural power that people can't see the eyes can be blessed with it, and evil will be driven away. These things that reduce protection and exorcism were later on the human body in the shape of a certain decoration, which became a specialized jewelry. Moreover, this custom and meaning have been retained, and the jewelry has also been given more beautiful sustenance and mysterious colors by humans.
