1, Introduction:

2. The predecessor of palindrome: the original decoration Yunlei.

Yun Leiwen is the original decorative pattern on bronzes and pottery. The pattern is curved into an arc or a square, and consists of continuous "back" lines. Some do circular continuous composition, referred to as "moire"; Some do continuous square composition, which is simply called "thunder pattern". Yun Leiwen is a general term for both. Yun Leiwen mostly uses ground patterns to set off the theme patterns, some of which appear on the neck or feet of utensils alone, and some techniques of expression such as patting, printing, drawing and painting. On the Guangdong bronze drum, Yun Leiwen, as the main decorative pattern, is often densely distributed around the sun pattern in the center of the drum surface, symbolizing that the sun and clouds and thunder exist in the sky, which is a reflection of the worship of clouds and thunder by southern nationalities.

Yun Leiwen appeared in the late Neolithic period, which may have developed from vortex patterns. Yun Leiwen appeared on bronzes in Shang and Zhou Dynasties and was still used in the Spring and Autumn Period and the Warring States Period. By the late Shang Dynasty, Yun Leiwen was relatively scarce, but Yun Leiwen was still the main decorative pattern on white pottery, hard pottery printed in Shang and Zhou Dynasties and primitive celadon.
