"the social changes in the warring States period, the development of productive forces and the various moral and cultural connotations given to jade by Confucianism made it fashionable for princes and nobles in the warring States period to wear jade. From the current archaeological materials, it can be seen that the variety of jade in the warring States period is richer than that in the Spring and Autumn period. it breaks through the decorative jade and burial jade which are mainly small pieces in the Spring and Autumn period, and presents large-scale jade sulfonate, jade wall, dragon-shaped dress, hook, etc.; the craftsmanship is more fine and exquisite, and most of them are good at the techniques of empty buildings, shallow relief, ingenious conception and unique shape. The decoration is more changeable, with not only grain patterns, moire patterns and other geometric patterns, but also spiral glaze patterns, mosaic patterns and patterns describing natural life. At the same time, the immortal beast shapes in the jade works of the warring States period are full of a tense momentum, which greatly enhances the inner spiritual rhythm and fully shows the Lingyun spirit of various princes in the warring States period who are full of ambition and desire to strive for hegemony.
