When did the jade culture in China begin?

Jade culture has accompanied Chinese civilization for thousands of years, which can be traced back to the Shang and Zhou Dynasties. At that time, the jade culture in China has been developing with civilization, which has entrusted us with too much feelings and wisdom.

The source of the work begins with the negative line, and the source of the device is born. The jade carving process started with simple yinxian, and gradually developed into double yinxian, yangxian, Tiqi, bas-relief and high relief ... from a small yinxian, many letters were reflected.

Rest. From jade cutting tools and jade processing techniques to ancient people's understanding of aesthetics, specific cultural background of the times and so on. Just like the Shang and Zhou jade articles, with the height of Wang Yu and Li Yu, they show distinctive and unique mysterious patterns and unique shapes, which have unique artistic charm.

Shang dynasty, this dynasty has its own unique integrity and domineering. Therefore, the performance of the negative line is straightforward and tough, and the curves are mostly connected by straight lines. Such as the typical word "minister", the construction method is rough and powerful. Jade wares in the early Shang Dynasty were represented by straight lines and thin pieces of jade. Late jades have symbolic and decorative features, such as three-dimensional figures and circular bird and beast carvings, which emphasize outstanding features and omit trivial details. At this time, most of the important details on jade will be engraved with double hook negative line or positive line, which can only be completed through four processes: hooking, cutting, squeezing and pressing.

Double hook yinxian means that two single yinxian lines are far apart.

Closely parallel and juxtaposed, decorated with patterns in the form of double lines, eye-catching but not monotonous. The characteristics of thick double hook yinxian are wide line mouth, deep groove, rough and bold shape, vigorous and powerful. Thin double hook negative thread is characterized by narrow thread opening, shallow groove, slender and ethereal shape, elegant and beautiful. In the late period, hidden and convex lines were developed on the basis of double hook lines, which enriched the carving techniques in the late Shang Dynasty.

The jade carving technology in the early Western Zhou Dynasty was basically the same as that in the Shang Dynasty. After the mid-Western Zhou Dynasty, it showed its own carving characteristics. On the technique of online carving, it was popular to use double hook yin carving to express patterns, and jade articles were smaller and smoother. Single shadow line, simple lines and strong knife method. Double negative lines, complex lines, curved corners, both rigid and flexible.

The original vertical shear yinxian gradually became vertical on one side and oblique on the other, and some developed into double hook vertical yinxian to express the three-dimensional sense and layering. Different from the stubborn lines in Shang Dynasty's Jin Jian, the double-yin-line hook-back method in the Western Zhou Dynasty is multi-arc, with a large slope and curved patterns. For example, the double hook is perpendicular to the negative line, instead of pressing the ground on both sides, one side presses the ground and the other side keeps the negative line, making the circle flexible. Graphic ornamentation basically developed into patterning, and the tortuous curves showed a unique sense of rhythm, which changed the aesthetic humor of Shang Dynasty.
