The Luminous Cup(夜光杯 Yeguangbei)

Yeguangbei (literally, the night-glittering cup) is a special jade product of Jiuquan, Gansu Province.

Since very ancient times, the QilianMountains of Gansu have produced a beautiful jade of brilliant white, green, black and yellow colors. Local artisans grind and polish it into wine cups either of a pure color or of mixed colors.

They are of various forms, wine cups with stems, flat-bottomed cups, and cups with cut designs, all marked by a simple and elegant taste. They are all the more cherished because they stand sudden contact with extreme heat or cold.

Legend says that King Mu (c.10th century B.C.) of the Zhou Dynasty once drank with this cup and found it glittering snowwhite in the moonlight. It was then named the “night-glittering cup”. It became more famous after the Tnag Dynasty poet Wang Han sang of it in the following lines:

Grape wine in luminous cups shine.

As we raise them to lips the pipa strikes up fast.

Laugh not if we fall drunk on the battlefield.

Tell us how many ever returned from the war.

Jiuquan has today a well-established factory specializing in the making of such “luminous cups”. Nowadays visitors to the town, apart from seeing JiayuguanPass, the western end of the Great Wall, all wish to make a tour of this factory buying a few cups as a souvenir.
