There are many short stories about wine in history. Write one at random and say it in concise language.

In ancient times, in a village in Henan, there was a farmer named Du Kang who had a pile of wheat straw at home. After fermentation in summer, it gives off a faint fragrance and drips liquid. Du Kang took the bowl to pick it up. Halfway through the bowl, an elderly man floated out of it. The elder told him that tomorrow you will take this bowl of water to the entrance of the village, wait for three strangers, and take a drop of blood from them and put it in the bowl, which will be very popular. The next day, Du Kang did it. It took a long time for a scholar to come because there were few pedestrians. Du Kang explained the reason, and the scholar replied generously. A few hours later, another samurai came. Du Kang still stated that the samurai did not hesitate to stab the wrist and drop blood; However, the third one didn't come for a long time, and it was only in Youshi that a madman came. Du Kang jumped on his finger and took a drop of blood. Three drops of blood dripped like a bowl, giving off an attractive fragrance at once. Later, Du Kang used this bowl of drinks as the base wine, mixed with water to make wine, and the business was booming. So this wine is three drops of blood, plus a unitary word. Moreover, when people drink, they are very civilized at first, which is the blood of literati; When you are happy, you will be brave, which is the blood of the samurai; Drinking until the end is nonsense, that is, the blood of a madman is at work.
