During the Wei and Jin periods (220-420), jade carving declined with the chaos brought about by frequent wars. However, the jade cup unearthed in 1956 in Luoyang City of Henan Province was like a lightning bolt through a heavy haze. It was made in the Wei Kingdom of the Three Kingdoms Period.

The jade cup, which is 13 cm high with a caliber of five cm and legs of four cm, was carved from a valuable Hetian Jade, and is white and smooth. It is shaped like a column with a straight cup abdomen. Completely unadorned, the cup still looks elegant and has an air of dignity. It belongs to the Luoyang cultural relic team.

During the Han Dynasty (206BC-AD220), jade ware was moved from noble families into ordinary people's homes. Their shapes assumed a more realistic style, although some parts were still very decorative. After the Han Dynasty, jade ware mainly served as decorations or everyday items. The jade cup reflects this change and therefore holds an important position, not only in the annals of Chinese arts and crafts, but also in the history of material culture.
