Ye Guang Bei--goblet made of black jade
I am lucky enough to see how to make Ye Guang Bei. The best place to see it is Jiu Quan, Chinese Satellite Base. There is a professional factory and the best Ye Guang Bei will be shipped out from there.
In ancient China, when the soldiers would fight against the enemy, they always drank Chinese Bai Jiu (wine made by rice) before they went out for the battle. The goblets they used are Ye Guang Bei. So from Ye Guang Bei, you may learn lots of moving stories.
