There is an interesting legend. According to legend, wine was invented and made by Du Kang. So how did he create wine, and why did he name this drink wine? The story goes like this: One day, Du Kang wanted to develop something that could be drunk, but he couldn't figure out how to make it. When he went to bed at night, he had a strange dream. He dreamed that an old man with white hair and a childish face came to him. He said to him: "You use water as the source and grain as the material. Then on the ninth day when the grain is soaked in water, find three people. Each person takes a drop of blood and adds it to it. That's it." After saying this, the old man disappeared. . When Du Kang woke up, he made it as the old man said. He went to the roadside to look for the three people at You hour (5 to 7 o'clock) on the ninth day. After a while, a scholar came, who was gentle, humble and polite. Du Kang hurriedly stepped forward to explain his purpose. Unexpectedly, the scholar readily agreed, cut his finger and dropped a drop of blood into the bucket. After the scholar left, another group of people came, and the leader He was a mighty and heroic general. Du Kang stepped forward to explain his intention. The general also rolled up his arms and sleeves to support Du Kang. He also cut his finger and dripped a drop of blood into the bucket. By this time, the unitary hour was almost over (in today's terms, it was about to come). It was seven o'clock) But Du Kang hadn't found the third person yet. He was a little anxious. Then he thought, wouldn't it be okay as long as he was a human being? So he found an unrelated and stupid beggar in the village, held him down, and A drop of blood dripped into the bucket after pricking his finger. The beggar suddenly screamed in pain and became dizzy at other times. With these three drops of blood, Du Kang finally made it, but he was worried again, what should he name it? When he thought about it, there were three people's blood in this drink, and it was dripped at Youshi, so he just wrote it as "wine". How to pronounce it? This was made on the ninth day, so let’s use the same pronunciation as wine (nine). This is the legend about the origin of wine.
