Brief introduction to the modeling and use of ancient jade articles in China.

Jade is a flat round jade with a hole in the middle, which is one of the traditional jade ritual vessels in China. Among the oblate jades with holes in the middle, those with small side width and aperture are called walls, while those with narrow side and large aperture are called rings. Zhou Li was written at the end of the Warring States Period, and six kinds of jade articles, such as Bi, Yan, Gui, Zhang, Hu and Huang, were collectively referred to as "six vessels" or "six vessels".

Emerald jade has a wide range of applications, which is not only a sign of power level, but also a gift or token in social activities.
