The biggest change of jade in the Western Zhou Dynasty is the variety of jade. The practical or impractical jade articles that prevailed from the Neolithic Age to the Shang Dynasty have gradually disappeared by this time; In the jade ritual vessels made by imitating actual combat weapons, at least in the Central Plains, jade knives and jade qi are not seen. Fishing songs and Yuqi have entered a period of decline, which is manifested in the fact that not only the number is small, but also the shape of utensils is developing towards miniaturization. Most of them have been reduced from tens of centimeters in the past to about 10 cm, and their uses have become symbolic, mainly for collecting treasures and goods; Jade Cong is a kind of ritual vessel. A large number of jade Cong were found in the seat of the Western Zhou Dynasty royal family, especially in Joo Won?, Shaanxi. Jade has tended to be miniaturized, and jade yellow and jade pots (that is, realistic jade and tiger vessels) have suddenly increased. Jade Gui first appeared in the Jade Group, but Jade Zhang has not seen the real thing. In this issue of Yu Pei, a major change is to break through the habit of focusing only on a single person in the past and develop into a group with certain specifications. Its form is composed of several jade yellow and many tube beads of different colors, hanging from the chest to the legs and feet, giving people a dazzling and magnificent freshness.

At this time, in addition to a few plastic upright lifelike human objects, there are still many human-dragon recombiners, squatting on the ground, with several dragons all over them, or wearing them as organs or accessories, and looking sideways or individuals from the right. Its system is peculiar and full of the times. Although there are a considerable number of realistic animal-shaped jade articles, there are fewer varieties than those in Shang Dynasty, that is, from dozens to dozens in Shang Dynasty, including cattle, sheep, pigs, rabbits, birds, tigers, deer, turtles, cicadas, silkworms, fish and mantis. Non-realistic birds and beasts, the phoenix that began to appear in the Neolithic period, reappeared after being interrupted by Xia and Shang Dynasties, and suddenly increased. In this issue of Phoenix-shaped works, there is a wooden club-shaped crown on the top of the head, which stands upright or bends forward, with a hooked mouth, wide eyes and a tail sticking up from the back to the top of the head. The shape of the dragon has also undergone great development and changes. In addition to some bottle-shaped horns and bipedal dragons between Yin and Shang dynasties, there are two or more new apetalous dragons with long tongues crossing each other. The sudden increase of these birds and beasts and the more abnormal mystery show that people at that time changed from worshipping nature and realistic animals in the early days to worshiping gods.

During the Western Zhou Dynasty, in addition to many traditional jade articles, some new jade articles appeared, including a group of jade articles and a jade mask specially used for burying the dead. The jade mask is made of several pieces of jade similar to the facial features, sewn on the cloth according to the size and shape of the face. Some are specially made, and some seem to be modified or merged from other jade articles. The number of pieces in each set is different, each piece is flat, and there are holes in the corners to facilitate sewing. When in use, all decorative parts face the face of the deceased. Tuanyu can make a beautiful jade sound and control people's moving pace according to certain rules, also known as jingle, knot and step. According to the known unearthed cultural relics, more than 10 sets have been found, all of which are owned by princes and nobles. In addition to the above steps, his use also means that he is in a high position and respects morality. He is a "gentleman" with "aboveboard" character, and he beautifies his clothes.

Most jade articles in the Western Zhou Dynasty have ornamentation and patterns. Look at its decorative patterns, quite distinctive, slightly different from previous issues. * * * is divided into two types: first, the decorative patterns are relatively simplified, which is manifested in the fact that a few negative lines are often used to represent the main patterns needed on a jade article, which has a special aesthetic feeling and a "finishing touch" effect. The so-called simplicity and elegance refers to this; Second, the layout of decorative patterns is dense, which is characterized by that when people or elephants are born, their eyebrows, feathers and claws are all concrete and meticulous, and their shapes are as close as the feelings of objects.

Another feature of the decorative patterns on jade articles in the Western Zhou Dynasty is simplicity and complexity. At first glance, it is similar to that in the Yin and Shang Dynasties, with a single negative line and a double hook. But on closer examination, the expression of engraving is different. For example, the single shadow line is often decorated with oblique weight, and the two sides of the line have different shades, showing a slope shape, similar to a diagonal knife. If it is a double hook line, the thickness of the double hook line is different. Thin words are similar to those of Shang dynasty, which seems to be carved with a vertical knife, and there is no sense of depth on both sides. Thick words, like the shape expressed by the single negative line mentioned above, are also decorated with oblique vertical frames.

The eye shape of people or elephants in jade articles in the Western Zhou Dynasty is similar to that in Shang Dynasty, especially in Yin and Shang Dynasties, and the word "minister" is also commonly used, but the corner of the eye of the word "minister" has an extension line on both sides of the eye pattern of this device. In addition, the decorative patterns of jade articles in the Western Zhou Dynasty are mainly dragon patterns and phoenix patterns, which pay attention to the mystery and grandeur of the decorative patterns, abstract deformation and smooth lines.
