China is one of the leading countries in wine-making in the world. There are many legends concerning the invention of alcohol. The most popular one is about Du Kang. It is said that Du Kang lost his bamboo tube, which was full of millet, on the tree one day. Fourteen days later he saw the tube by accident, and surprisingly found that the millet had turned into fragrant alcohol. Since then, inspired by this discovery, he began to make the alcohol. And for that reason, his name is often associated with alcohol, which is illustrated in Cao Cao's verses-“What can relieve my worries? Only Dukang.”
